+1 Notes on the Free Translation Project
+***************************************
+
+Free software is going international! The Free Translation Project is
+a way to get maintainers of free software, translators, and users all
+together, so that free software will gradually become able to speak many
+languages. A few packages already provide translations for their
+messages.
+
+ If you found this `ABOUT-NLS' file inside a distribution, you may
+assume that the distributed package does use GNU `gettext' internally,
+itself available at your nearest GNU archive site. But you do _not_
+need to install GNU `gettext' prior to configuring, installing or using
+this package with messages translated.
+
+ Installers will find here some useful hints. These notes also
+explain how users should proceed for getting the programs to use the
+available translations. They tell how people wanting to contribute and
+work on translations can contact the appropriate team.
+
+ When reporting bugs in the `intl/' directory or bugs which may be
+related to internationalization, you should tell about the version of
+`gettext' which is used. The information can be found in the
+`intl/VERSION' file, in internationalized packages.
+
+1.1 Quick configuration advice
+==============================
+
+If you want to exploit the full power of internationalization, you
+should configure it using
+
+ ./configure --with-included-gettext
+
+to force usage of internationalizing routines provided within this
+package, despite the existence of internationalizing capabilities in the
+operating system where this package is being installed. So far, only
+the `gettext' implementation in the GNU C library version 2 provides as
+many features (such as locale alias, message inheritance, automatic
+charset conversion or plural form handling) as the implementation here.
+It is also not possible to offer this additional functionality on top
+of a `catgets' implementation. Future versions of GNU `gettext' will
+very likely convey even more functionality. So it might be a good idea
+to change to GNU `gettext' as soon as possible.
+
+ So you need _not_ provide this option if you are using GNU libc 2 or
+you have installed a recent copy of the GNU gettext package with the
+included `libintl'.
+
+1.2 INSTALL Matters
+===================
+
+Some packages are "localizable" when properly installed; the programs
+they contain can be made to speak your own native language. Most such
+packages use GNU `gettext'. Other packages have their own ways to
+internationalization, predating GNU `gettext'.
+
+ By default, this package will be installed to allow translation of
+messages. It will automatically detect whether the system already
+provides the GNU `gettext' functions. If not, the included GNU
+`gettext' library will be used. This library is wholly contained
+within this package, usually in the `intl/' subdirectory, so prior
+installation of the GNU `gettext' package is _not_ required.
+Installers may use special options at configuration time for changing
+the default behaviour. The commands:
+
+ ./configure --with-included-gettext
+ ./configure --disable-nls
+
+will, respectively, bypass any pre-existing `gettext' to use the
+internationalizing routines provided within this package, or else,
+_totally_ disable translation of messages.
+
+ When you already have GNU `gettext' installed on your system and run
+configure without an option for your new package, `configure' will
+probably detect the previously built and installed `libintl.a' file and
+will decide to use this. This might not be desirable. You should use
+the more recent version of the GNU `gettext' library. I.e. if the file
+`intl/VERSION' shows that the library which comes with this package is
+more recent, you should use
+
+ ./configure --with-included-gettext
+
+to prevent auto-detection.
+
+ The configuration process will not test for the `catgets' function
+and therefore it will not be used. The reason is that even an
+emulation of `gettext' on top of `catgets' could not provide all the
+extensions of the GNU `gettext' library.
+
+ Internationalized packages usually have many `po/LL.po' files, where
+LL gives an ISO 639 two-letter code identifying the language. Unless
+translations have been forbidden at `configure' time by using the
+`--disable-nls' switch, all available translations are installed
+together with the package. However, the environment variable `LINGUAS'
+may be set, prior to configuration, to limit the installed set.
+`LINGUAS' should then contain a space separated list of two-letter
+codes, stating which languages are allowed.
+
+1.3 Using This Package
+======================
+
+As a user, if your language has been installed for this package, you
+only have to set the `LANG' environment variable to the appropriate
+`LL_CC' combination. If you happen to have the `LC_ALL' or some other
+`LC_xxx' environment variables set, you should unset them before
+setting `LANG', otherwise the setting of `LANG' will not have the
+desired effect. Here `LL' is an ISO 639 two-letter language code, and
+`CC' is an ISO 3166 two-letter country code. For example, let's
+suppose that you speak German and live in Germany. At the shell
+prompt, merely execute `setenv LANG de_DE' (in `csh'),
+`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
+This can be done from your `.login' or `.profile' file, once and for
+all.
+
+ You might think that the country code specification is redundant.
+But in fact, some languages have dialects in different countries. For
+example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The
+country code serves to distinguish the dialects.
+
+ The locale naming convention of `LL_CC', with `LL' denoting the
+language and `CC' denoting the country, is the one use on systems based
+on GNU libc. On other systems, some variations of this scheme are
+used, such as `LL' or `LL_CC.ENCODING'. You can get the list of
+locales supported by your system for your language by running the
+command `locale -a | grep '^LL''.
+
+ Not all programs have translations for all languages. By default, an
+English message is shown in place of a nonexistent translation. If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG'
+for the purpose of message handling, but you still need to have `LANG'
+set to the primary language; this is required by other parts of the
+system libraries. For example, some Swedish users who would rather
+read translations in German than English for when Swedish is not
+available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
+
+ Special advice for Norwegian users: The language code for Norwegian
+bokma*l changed from `no' to `nb' recently (in 2003). During the
+transition period, while some message catalogs for this language are
+installed under `nb' and some older ones under `no', it's recommended
+for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and
+older translations are used.
+
+ In the `LANGUAGE' environment variable, but not in the `LANG'
+environment variable, `LL_CC' combinations can be abbreviated as `LL'
+to denote the language's main dialect. For example, `de' is equivalent
+to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
+(Portuguese as spoken in Portugal) in this context.
+
+1.4 Translating Teams
+=====================
+
+For the Free Translation Project to be a success, we need interested
+people who like their own language and write it well, and who are also
+able to synergize with other translators speaking the same language.
+Each translation team has its own mailing list. The up-to-date list of
+teams can be found at the Free Translation Project's homepage,
+`http://translationproject.org/', in the "Teams" area.
+
+ If you'd like to volunteer to _work_ at translating messages, you
+should become a member of the translating team for your own language.
+The subscribing address is _not_ the same as the list itself, it has
+`-request' appended. For example, speakers of Swedish can send a
+message to `sv-request@li.org', having this message body:
+
+ subscribe
+
+ Keep in mind that team members are expected to participate
+_actively_ in translations, or at solving translational difficulties,
+rather than merely lurking around. If your team does not exist yet and
+you want to start one, or if you are unsure about what to do or how to
+get started, please write to `coordinator@translationproject.org' to
+reach the coordinator for all translator teams.
+
+ The English team is special. It works at improving and uniformizing
+the terminology in use. Proven linguistic skills are praised more than
+programming skills, here.
+
+1.5 Available Packages
+======================
+
+Languages are not equally supported in all packages. The following
+matrix shows the current state of internationalization, as of May 2010.
+The matrix shows, in regard of each package, for which languages PO
+files have been submitted to translation coordination, with a
+translation percentage of at least 50%.

+
+ Some counters in the preceding matrix are higher than the number of
+visible blocks let us expect. This is because a few extra PO files are
+used for implementing regional variants of languages, or language
+dialects.
+
+ For a PO file in the matrix above to be effective, the package to
+which it applies should also have been internationalized and
+distributed as such by its maintainer. There might be an observable
+lag between the mere existence a PO file and its wide availability in a
+distribution.
+
+ If May 2010 seems to be old, you may fetch a more recent copy of
+this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date
+matrix with full percentage details can be found at
+`http://translationproject.org/extra/matrix.html'.
+
+1.6 Using `gettext' in new packages
+===================================
+
+If you are writing a freely available program and want to
+internationalize it you are welcome to use GNU `gettext' in your
+package. Of course you have to respect the GNU Library General Public
+License which covers the use of the GNU `gettext' library. This means
+in particular that even non-free programs can use `libintl' as a shared
+library, whereas only free software can use `libintl' as a static
+library or use modified versions of `libintl'.
+
+ Once the sources are changed appropriately and the setup can handle
+the use of `gettext' the only thing missing are the translations. The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project. Therefore the information given above
+applies also for every other Free Software Project. Contact
+`coordinator@translationproject.org' to make the `.pot' files available
+to the translation teams.

+Authors of GNU Bison.
+
+Bison was written primarily by Robert Corbett.
+
+Richard Stallman made it Yacc-compatible.
+
+Wilfred Hansen of Carnegie Mellon University added multicharacter
+string literals and other features (Bison 1.25, 1995).
+
+Akim Demaille rewrote the parser in Bison, and changed the back end to
+use M4 (1.50, 2002).
+
+Paul Hilfinger added GLR support (Bison 1.50, 2002).
+
+Joel E. Denny contributed canonical-LR support, and invented and added
+IELR and LAC (Lookahead Correction) support (Bison 2.5, 2011).
+
+Paolo Bonzini contributed Java support (Bison 2.4, 2008).
+
+Alex Rozenman added named reference support (Bison 2.5, 2011).
+
+Paul Eggert fixed a million portability issues, arbitrary limitations,
+and nasty bugs.

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ api.prefix: also rename YYDEBUG.
+ The testsuite in master has shown weird errors for the "Mulitple
+ Parsers" tests: the caller of p5.parse() received some apparently
+ random value, while tracing p5.parse() showed that the function was
+ consistently returning 0.
+
+ It happens when mixing several parser headers, some generated without
+ %debug, others with. In particular the C++ parser was generated with
+ %debug, i.e., with:
+
+ #ifndef YYDEBUG
+ # define YYDEBUG 1
+ #endif
+
+ and compiled separatedly. Yet, its header was included after the one
+ of another parser, this time without %debug, i.e., with
+
+ #ifndef YYDEBUG
+ # define YYDEBUG 0
+ #endif
+
+ in its header. As a result, the parser was compiled with YYDEBUG set,
+ but its header was used without. Since the layout of the objects are
+ then completely different, boom.
+
+ Therefore, do not change the value of YYDEBUG. Rather, use it as a
+ default value for <API.PREFIX>DEBUG.

+ do not ignore errors like ENOSPC,EIO when writing to stdout
+ Standard output was never explicitly closed, so we could not
+ detect failure. Thus, bison would ignore the errors of writing
+ to a full file system and getting an I/O error on write, but only
+ for standard output, e.g., for --print-localedir, --print-datadir,
+ --help and some verbose output.
+ Now, "bison --print-datadir > /dev/full" reports the write failure:
+ bison: write error: No space left on device
+ Before, it would exit 0 with no diagnostic, implying success.
+ This is not an issue for "--output=-" or the other FILE-accepting
+ command-line options, because unlike most other GNU programs,
+ an output file argument of "-" is treated as the literal "./-",
+ rather than standard output.
+ * bootstrap.conf (gnulib_modules): Add closeout.

+ Don't use IF_LINT in Bison sources.
+ It creates unnecessary differences between the sources that Bison
+ maintainers build and test (given that maintainers normally
+ configure with --enable-gcc-warnings) and the sources that Bison

+ * src/scan-gram.l, src/scan-skel.l: Replace uses of IF_LINT with

+
+ doc: clean up naming of various Bison files.
+ The Bison manual's names for various files associated with a Bison
+ parser has devolved into inconsistency. This patch makes the
+ naming consistent for the most important files. First, it chooses
+ "grammar file" over "input file". The former appears to be more
+ traditional in the Bison manual, and Bison has other input
+ files (skeletons). Second, it chooses "parser implementation
+ file" over names like "parser file", "parser source file", "parser
+ source code file", and "parser output file". The new name makes
+ it clearer where Bison generates the main parser implementation,
+ and it is easily distinguishable from "parser header file".
+ * doc/bison.texinfo: Implement throughout.

+
+ doc: document experimental features better.
+ * doc/bison.texinfo (Introduction): Say that IELR(1) and canonical
+ LR(1) are experimental. Mention Java. Normally experimental
+ features probably shouldn't be mentioned in the introduction.
+ However, if Bison's limitations to LALR(1), C, and C++ are so
+ important that they should be mentioned here, then it's important
+ to point out that Bison is beginning to escape those limitations.
+ Moreover, these particular experimental features have very little
+ chance of being removed.

+
+ Do not allow identifiers that start with a dash.
+ This cleans up our previous fixes for a bug whereby Bison
+ discarded `.field' in `$-1.field'. The previous fixes were less
+ restrictive about where a dash could appear in an identifier, but
+ the restrictions were hard to explain. That bug was reported and
+ this final fix was originally suggested by Paul Hilfinger. This
+ also fixes a remaining bug reported by Paul Eggert whereby Bison
+ parses `%token ID -123' as `%token ID - 123' and handles `-' as an
+ identifier. Now, `-' cannot be an identifier. Discussed in
+ threads beginning at
+ <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>,
+ <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00004.html>.
+ * NEWS (2.5): Update entry describing the dash extension to
+ grammar symbol names. Also, move that entry before the named
+ references entry because the latter mentions the former.
+ * doc/bison.texinfo (Symbol): Update documentation for symbol
+ names. As suggested by Paul Eggert, mention the effect of periods
+ and dashes on named references.
+ (Decl Summary): Update documentation for unquoted %define values,

+
+ Improve error messages for `$' or `@' followed by `.' or `-'.
+ Previously, for this special case of an invalid reference, the
+ usual "symbol not found in production:" was printed. However,
+ because the symbol name was parsed as the empty string, that
+ message was followed immediately by a newline instead of a symbol
+ name. In reality, this is a syntax error, so the reference is
+ invalid regardless of the symbols actually appearing in the
+ production. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00012.html>.
+ * src/scan-code.l (parse_ref): Report the above case as a syntax
+ error. Other than that, continue to handle this case like any
+ other invalid reference that Bison manages to parse because
+ "possibly meant" messages can still be helpful to the user.
+ * tests/named-refs.at ($ or @ followed by . or -): New test group.

+ * data/yacc.c: Rename %define variable parse.lac.es-capacity to

+ (YYSTACK_USE_ALLOCA): Ignore it if LAC requested.
+ (YYSTACK_ALLOC, YYSTACK_FREE, YYSTACK_ALLOC_MAXIMUM): Define if
+ LAC requested.
+ (YYCOPY_NEEDED): New cpp macro.
+ (YYCOPY): Define if LAC requested.
+ (yy_lac_stack_realloc): New function implementing stack
+ reallocations. Use YYMAXDEPTH for maximum stack size given that
+ the stack should never need to grow larger than the main state
+ stack needs to grow without LAC.
+ (YY_LAC_ESTABLISH): Update yy_lac invocation.
+ (yy_lac): Add arguments for exploratory stack memory data
+ recorded in the main parser. Invoke yy_lac_stack_realloc when
+ reallocation is necessary.
+ (yysyntax_error): Add the same new arguments and pass them to
+ yy_lac.
+ (yypstate_delete): Free yyes if necessary.
+ (yyesa, yyes, yyes_capacity): #define these to yypstate members
+ in the case of push parsing.
+ (yyparse, yypush_parse): Initialize yyes and yyes_capacity.
+ Update yysyntax_error invocations. At yyreturn, free yyes if
+ necessary.
+ * src/parse-gram.y: %define parse.lac full.

+
+2010-12-11 Joel E. Denny <joeldenny@joeldenny.org>
+
+ parse.lac: implement as %define variable.
+ LAC = lookahead correction. See discussion at
+ <http://lists.gnu.org/archive/html/bison-patches/2009-09/msg00034.html>.
+ However, one point there must be corrected: because of %nonassoc,
+ LAC is *not* always redundant for lr.type=canonical-lr.
+ * data/yacc.c: Accept values of "none" (default) or "full" for
+ parse.lac. Accept %define parse.lac.es-capacity to specify
+ capacity of LAC's temporary exploratory stack. It defaults to 20
+ and, for now, will not grow dynamically.
+ (b4_lac_flag, b4_lac_if): New m4 macros. Evaluate as true for
+ parse.lac!=none.
+ (YYBACKUP): Invoke YY_LAC_DISCARD.
+ (YY_LAC_ESTABLISH, YY_LAC_DISCARD): New cpp macros that invoke
+ yy_lac and track when it needs to be invoked
+ (yy_lac): New function that, given the current stack, determines
+ whether a token can eventually be shifted. Return status mimics
+ yyparse return status.
+ (yysyntax_error): Change yystate argument to yyssp so stack top
+ can be passed to yy_lac. If LAC is requested, build expected
+ token list by invoking yy_lac for every token instead of just
+ checking the current state for lookaheads. Return 2 if yy_lac
+ exhausts memory.
+ (yyparse, yypush_parse): Use local variable yy_lac_established and
+ cpp macros YY_LAC_ESTABLISH and YY_LAC_DISCARD to implement LAC.
+ Update yysyntax_error invocation. Add yyexhaustedlab code if LAC
+ is requested.
+ * tests/conflicts.at (%nonassoc and eof): Extend to check the
+ effect of each of -Dlr.type=canonical-lr and -Dparse.lac=full.
+ (%error-verbose and consistent errors): Likewise.
+ (LAC: %nonassoc requires splitting canonical LR states): New test
+ group demonstrating how LAC can fix canonical LR.

+ manipulation in user semantic actions" wasn't adjusted for that
+ difference.
+ * data/lalr1.cc (yy::parser::parse): Translate yychar before
+ every use of yytoken, and add comments explaining this approach.
+ * tests/conflicts.at (%error-verbose and consistent errors):
+ Extend to test yychar manipulation with lalr1.cc.
+
+2010-11-07 Joel E. Denny <joeldenny@joeldenny.org>
+
+ yysyntax_error: fix for consistent error with lookahead.
+ * NEWS (2.5): Document.
+ * data/yacc.c (yysyntax_error): In a verbose syntax error
+ message while in a consistent state with a default action (which
+ must be an error action given that yysyntax_error is being
+ invoked), continue to drop the expected token list, but don't
+ drop the unexpected token unless there actually is no lookahead.
+ Moreover, handle that internally instead of returning 1 to tell

+ Fix portability problem on OpenBSD 4.7.
+
+ Jim Meyering reported this in
+ <http://lists.gnu.org/archive/html/bug-bison/2010-10/msg00007.html>.
+ * data/yacc.c: Use EXIT_SUCCESS as a witness for stdlib.h,
+ not _STDLIB_H. EXIT_SUCCESS has been defined by the standard
+ for quite some time.
+ * src/parse-gram.c, src/parse-gram.h: Regenerate.
+ * tests/regression.at: Tamper with the renamed witness.
+
+ Adjust to recent changes to gnulib bootstrap.
+
+ * .cvsignore, build-aux/.cvsignore, doc/.cvsignore, etc/.cvsignore:
+ * examples/calc++/.cvsignore, lib/.cvsignore, m4/.cvsignore:
+ * po/.cvsignore, runtime-po/.cvsignore, src/.cvsignore:
+ * tests/.cvsignore: Remove; I don't use CVS to maintain Bison
+ anymore and don't know of anybody else who does. If someone needs
+ these files, they can resurrect them.
+ * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore:
+ * m4/.gitignore, po/.gitignore, runtime-po/.gitignore:
+ Omit leading '/', since bootstrap omits it.
+ Adjust file names to match current contents better.
+ * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook
+ installed just for us.
+ * bootstrap.conf (excluded_files): Don't exclude codeset.m4,
+ glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
+ needed somehow. Don't have time to look into why.
+ (gnulib_modules): Change malloc to malloc-gnu. Do we really assume
+ the GNU malloc behavior, where malloc (0) != NULL unless we're
+ out of storage? If not, we can omit malloc-gnu; but for now I left
+ it in to be safe.
+ (vc_ignore): Remove.
+ * README-hacking: Renamed from HACKING, since gnulib bootstrap now
+ uses that convention.

+ scan_skel. As a result, broken-pipe messages from M4 were seen
+ on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
+ failure in the test suite. The problem was that, on platforms
+ where the default disposition for SIGPIPE is ignore instead of
+ terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
+ then reported it. However, there's some sort of race condition,
+ because the new test group occasionally succeeded.
+ Reported by Albert Chin at
+ <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
+
+ There were also problems with the test suite livelocking on
+ Tru64 5.1b. Reported by Didier Godefroy at
+ <http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
+ Switching to create_pipe_bidi suggested by Akim Demaille.
+
+ To attempt to solve both of these problems, switch to gnulib's
+ create_pipe_bidi and register M4 process as a slave. Along the
+ way, clean up file name conflict handling, which was affected by
+ the broken-pipe problem before the switch.

+
+ Fix handling of yychar manipulation in user semantic actions.
+ The problem was that yacc.c didn't always update the yychar
+ translation afterwards. However, other skeletons appear to be
+ fine. glr.c appears to already translate yychar before every
+ use. lalr1.cc does not define yychar and does not document its
+ replacement, yyla, for users. It does provide yyclearin, but
+ that does not manipulate yyla and thus requires no translation
+ update. In lalr1.java, yychar is out of scope during semantic
+ actions.
+ * NEWS (2.5): Document.
+ * data/yacc.c (YYBACKUP): Don't bother translating yychar into
+ yytoken here.
+ (yyparse, yypush_parse): Instead, translate before every use of
+ yytoken, and add comments explaining this approach.
+ * tests/actions.at (Destroying lookahead assigned by semantic
+ action): New test group checking that translation happens before
+ lookahead destructor calls at parser return. Previously,
+ incorrect destructors were called.
+ * tests/conflicts.at (%error-verbose and consistent
+ errors): New test group checking that translation happens at
+ syntax error detection before the associated verbose error
+ message and the associated lookahead destructor calls. While
+ the destructor call is fixed by this patch, the verbose error
+ message is currently incorrect due to another bug (see
+ comments in test group), so this is an expected failure for now.

+ (yyis_table_ninf): Rename to...

+ appears that this check is always performed before this function
+ is invoked, and so adding the check here is probably redundant.
+ However, the code may evolve after this subtlety is forgotten.
+ Also, update for rename to yytable_value_is_error. Because that

+ * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
+ For a \0 and similar escape sequences meaning the null
+ character, report an invalid escape sequence instead of an
+ invalid null character because the latter does not actually
+ appear in the user's input.
+ In all escape sequence complaints, don't escape the initial
+ backslash, and don't quote when the sequence appears at the end
+ of the complaint line unless there's whitespace that quotearg
+ won't escape.
+ Consistently say "invalid" not "unrecognized".
+ Consistently prefer "empty character literal" over "extra

+ sequences; that is, consistently discard those sequences.

+ * src/output.c (prepare_symbols): When writing yytname muscles, where
+ symbol names will be encoded in C-string literals, tell quotearg to
+ escape trigraphs. This used to be the default in gnulib.
+ * tests/regression.at (Token definitions): Because of the change in
+ gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
+ escapes trigraphs in symbol names. Thus, yytname no longer has
+ trigraphs unnecessarily doubly escaped. Update test case output.
+ Extend test case to be sure Bison's own error messages will no longer
+ have trigraphs in symbol names unnecessarily escaped once.

+
+ Improve handling of multiple S/R conflicts in the same state and of S/R
+ conflicts involving multiple reductions.
+ * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
+ set for a state here or Bison will abort if it is reassigned on a
+ later conflicted reduction in the same state.
+ Similarly, don't finalize and assign the solved conflicts report here
+ or it will be lost if it is reassigned on a later conflicted reduction
+ in the same state.
+ (set_conflicts): Instead, assign them both here after all S/R conflicts
+ in the state have been fully examined.
+ * src/print.c (shift_set): Rename to...
+ (no_reduce_set): ... this.
+ (print_reductions): Update for rename, and add %nonassoc error action
+ tokens to no_reduce_set so that, when printing the first remaining
+ reduction on an error action token, the reduction is enclosed in
+ brackets.
+ (print_results): Update for rename.
+ * tests/conflicts.at (Solved conflicts report for multiple reductions
+ in a state): New test case.
+ (%nonassoc error actions for multiple reductions in a state): New test
+ case.
+
+ * src/main.c (main): Don't depend on C99 features.

+
+ * build-aux/.cvsignore: Add compile.

+
+2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * bootstrap (slurp): Create target directories that don't exist.
+ Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
+
+2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * LR0.c (new_itemsets): Fix wording in comments: say item index rather

+ * closure.c (closure): Likewise.
+ * state.h (reductions): Comment sorting of rules.
+ (state): Comment sorting of items.
+
+2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix C++ test cases after recent Gnulib changes. Discussed starting at
+ <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
+ * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
+ definition in order to avoid Gnulib headers since we don't use config.h
+ here.
+ * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
+ rather than AT_DATA so that config.h is included.
+
+2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
+ instead of fprintf. Guard these functions with #if YYDEBUG instead of
+ #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
+ and so that YYFPRINTF is guaranteed to be defined here.
+
+2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
+ with...

+ Again, it's not used yet, but it will be.
+ * src/muscle_tab.h: Likewise.
+
+ Improve some comments in parser table construction.
+ * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
+ (generate_states): Don't mention ruleset, which is internal to closure.
+ * src/closure.c (closure): Explain sorting of core and itemset, which
+ is required for this function to behave correctly.
+ * src/closure.h (closure): Mention sorting.
+
+2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/lalr.c (state_lookahead_tokens_count): For code readability,
+ move the check for disabled transitions to an aver since conflict
+ resolution hasn't happened yet.
+
+ * src/lalr.c (state_lookahead_tokens_count): Remove the check that
+ labels a state as inconsistent just because it has error transitions.
+ The original form of this check appeared in revision 1.1 of lalr.c,
+ which was committed on 1991-12-21. Now (at least), changing the
+ consistency label on such a state appears to have no useful effect in
+ any of the places it is examined, which I enumerate below. The key
+ point to understanding each item in this enumeration is that a state
+ with an error transition is labelled consistent in the first place only
+ if it has no rules, so the check cannot matter for states that have
+ rules. (1) Labelling a state as inconsistent will cause set_conflicts
+ to try to identify its conflicts, and a state must have *rules* to have
+ conflicts. (2) Labelling a state as inconsistent will affect how
+ action_row sets the default *rule* for the state. (3) Labelling a
+ state as inconsistent will cause build_relations to add lookback edges
+ to *rules* in that state.
+ * src/state.h (struct state): Word the comment for member consistent
+ more carefully.

+ must later be reported as invalid.
+ * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New

+ Undo my 2007-02-07 change, switching back to the c-strcase module
+ introduced in the 2007-02-03 change. Bruno Haible reported that
+ the 2007-02-07 change would be dangerous in Turkish if we add a
+ language whose name contains "i", since "i" is not lowercase "I"
+ in Turkish.
+ * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
+ * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,

+ (yypstate_new): Return NULL if malloc does.
+ * src/reader.c (packgram): Move translation of rule actions from the
+ beginning of packgram to...
+ (check_and_convert_grammar): ... here right before packgram is invoked

+ * src/getargs.c: Revert 2007-02-03 change, as follows.
+ Don't include c-strcase.h.
+ (language_argmatch): Use strcasecmp rather than c_strcasecmp.
+ strcasecmp has "unspecified behavior" outside the POSIX locale,
+ but it works fine in practice if at least one argument is ASCII,
+ as is the case in Bison.
+
+2007-02-07 Paolo Bonzini <bonzini@gnu.org>

+ to the instance of Stack used by parse(). Reported by Paul Eggert.
+
+2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
+
+ * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really

+
+ Clean up.
+ * src/scan-skel.l (at_directive_perform): Add at_directive_argc and

+ (fail_for_at_directive_too_many_args,
+ fail_for_at_directive_too_few_args): Add at_directive_name argument.
+ (at_directive_name): Remove as at_directive_argv[0] will be used for

+ (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
+ for the directive name.
+ (at_directive_argc, at_directive_argv): Make these local within

+
+2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * ChangeLog: For changes in doc/bison.texinfo, consistently reference
+ node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
+ Summary" not "Directives".
+ * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
+ %code entry in "Decl Summary" rather than the one in "Table of Symbols"
+ since the former is now the more complete one.
+ (Prologue Alternatives): Likewise and do the same for %defines.
+ (Table of Symbols): Add summary of %code, add summary of %define, and
+ move full %code documentation to...
+ (Decl Summary): ... here for consistency with other entries in these
+ sections.
+ Move %define entry in order to keep this list alphabetized.
+ Reword %define entry a little to put less emphasis on the skeleton
+ concept, which most users shouldn't have to think about.

+
+ Clean up %define and %code implementation in M4 some. Most
+ importantly, rename all related macros to be in the b4_percent_define

+ * data/bison.m4 (b4_check_user_names): Check for special
+ "SKELETON-NAMESPACE(name)" macros instead of using two nested
+ m4_foreach loops.
+ (b4_get_percent_define, b4_get_percent_code): Rename to...
+ (b4_percent_define_get, b4_percent_code_get): ... these.
+ Extend documentation with examples.
+ For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

+ Use m4_indir so that %define variable names and %code qualifiers can

+ * data/c++.m4: Use b4_percent_define_default rather than

+ * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,

+ * src/output.c (prepare): Remove muscle insertion of the prologues.
+ (output): Remove freeing of pre_prologue_obstack and
+ post_prologue_obstack.
+ * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
+ than prologue_augment for prologue parsing so you don't need prologue
+ obstacks.
+ (grammar_declaration): For %union RHS, use `braceless' instead of
+ "{...}" so that braces are already stripped and code is escaped with

+
+2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Instead of having skeletons declare all valid %define variables and
+ %code qualifiers, provide macros that retrieve the associated values
+ and build these lists automatically. Thus Bison will now warn when a
+ variable or qualifier is not used by the skeleton in the current
+ invocation regardless of whether it might sometimes be used by that
+ skeleton in other invocations. Also, move all %define value macros to
+ the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
+ form, which is replaced by %code.
+ * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
+ (b4_check_user_names): ... this, and change the series of valid name
+ arguments to a single list argument for names used in the skeleton
+ similar to the existing list argument for names used in the grammar.
+ Warn instead of complaining.
+ (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
+ values and %code code, to format %code code properly, and to build
+ lists of all %define variables and %code qualifiers used in the
+ skeleton: b4_skeleton_percent_define_variables and
+ b4_skeleton_percent_code_qualifiers.
+ (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
+ Remove, and...
+ (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
+ the skeleton names lists can finish building first. In place of
+ b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
+ expect the lists b4_user_percent_define_variables and
+ b4_user_percent_code_qualifiers.
+ * data/c++.m4: Where setting default values for b4_parser_class_name,
+ b4_location_type, b4_filename_type, b4_namespace, and
+ b4_define_location_comparison, update their names to the
+ b4_percent_define_ namespace.
+ * data/glr.c: Don't use b4_check_percent_define_variables and
+ b4_check_percent_code_qualifiers. Use b4_get_percent_code.
+ * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
+ (b4_parser_class_name, b4_namespace): Define these using
+ b4_get_percent_define for parser_class_name and namespace.
+ * data/location.cc: Use b4_get_percent_define.
+ * data/push.c: Don't use b4_check_percent_define_variables and
+ b4_check_percent_code_qualifiers. Use b4_get_percent_code.
+ * data/yacc.c: Likewise, and don't call m4_exit in
+ b4_use_push_for_pull_if or m4_wrap code will never execute.
+ * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
+ Rename to...
+ (muscle_grow_user_name_list): ... this for consistency with the
+ terminology used in bison.m4.
+ * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
+ %define variable names, and rename muscle used_percent_define_variables
+ to user_percent_define_variables.
+ (grammar_declaration): Rename muscle used_percent_code_qualifiers to
+ user_percent_code_qualifiers.
+ (content): Remove.
+ (content.opt): Replace content RHS with STRING RHS so %define "NAME"
+ {CODE} form is no longer accepted.
+ * tests/input.at (Reject bad %code qualifiers): Rename to...
+ (Reject unused %code qualifiers): ... this, and update test output.
+ (%define error): Update test output.
+
+2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Check for unrecognized %define variables similar to checking for

+ * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
+ generalizes...
+ (b4_check_percent_code_qualifiers): ... this, which now wraps it.
+ (b4_check_percent_define_variables): New, also wraps it.
+ * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
+ variables using b4_check_percent_define_variables.
+ * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
+ all those exercised in the test suite and all those listed in the

+ * data/push.c, data/yacc.c: Declare no valid %define variables.
+ * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,

+2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Provide warn_at, complain_at, and fatal_at function callbacks to the

+ the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
+ @fatal_at(...@) directives.
+ (b4_check_percent_code_qualifiers): Rewrite to expect locations for

+2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
+ unreliable -- especially when they're hidden inside another macro.
+ * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,

+ * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
+ data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with

+ * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
+ an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
+ pushed and popped by m4sugar, should be first on the stack.
+
+ Provide warn, complain, and fatal function callbacks to the skeletons.
+ This provides more flexibility than m4_fatal, improves the error

+ starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
+ * data/bison.m4 (b4_error): New, invoked by...
+ (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
+ skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
+ directives. Because these M4 macros might be called when the current
+ diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
+ the previous removal of uses of m4_divert, which caused trouble.
+ (b4_check_percent_code_qualifiers): Use b4_complain instead of
+ m4_fatal to report unrecognized %code qualifiers.
+ * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++

+ * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
+ are replaced by b4_percent_code_provides and b4_percent_code_requires,
+ which are skeleton-specific.
+ (b4_check_percent_code_qualifiers): New. A skeleton can use this to
+ declare what %code qualifiers it supports and to complain if any other
+ qualifiers were used in the grammar.
+ * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
+ and b4_user_code([b4_percent_code_provides]) in place of
+ b4_user_requires and b4_user_provides.
+ * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
+ Add b4_user_code([b4_percent_code_top]) and
+ b4_user_code([b4_percent_code]).
+ Invoke b4_check_percent_code_qualifiers.
+ * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
+ PERCENT_REQUIRES): Remove.
+ (grammar_declaration): Remove RHS's for %code-top, %provides, and
+ %requires. Rewrite the %code RHS as the unqualified form defining the
+ muscle b4_percent_code. Add another RHS for the qualified %code form,
+ which defines muscles of the form b4_percent_code_QUALIFIER and the
+ b4_used_percent_code_qualifiers muscle.
+ * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
+ PERCENT_REQUIRES): Remove.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use

+2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Use the new code_props interface for destructors and printers.
+ * src/symtab.h (symbol, semantic_type): Remove destructor_location and

+ default_tagless_printer_set): Use code_props in arguments and return

+ (symbol_destructor_location_get, symbol_printer_location_get): Remove
+ since the locations are now contained in the return of
+ symbol_destructor_get and symbol_printer_get.
+ * src/output.c (symbol_destructors_output, symbol_printers_output):
+ Replace with...
+ (symbol_code_props_output): ... this to eliminate duplicate code.

+ of these to code_props.
+ (symbol_new, semantic_type_new, symbol_destructor_set,

+ (symbol_print): Use SYMBOL_CODE_PRINT.
+
+2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Use the new code_props interface for rule actions.
+ * src/symlist.h (symbol_list): Replace action, action_location, and

+
+2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Use the new code_props interface in parse-gram.y.
+ * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
+ Update all uses of translate_* functions to use the new code_props
+ interface and to use gram_scanner_last_string_free and
+ code_scanner_last_string_free where possible.
+ (grammar_declaration): symbol_list_destructor_set and
+ symbol_list_printer_set now perform the translation, so don't do it
+ here. Use gram_scanner_last_string_free where possible.
+ * src/scan-code.h, src/scan-code.l (translate_symbol_action,
+ translate_code): Remove, no longer used.
+ * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
+ symbol_list_printer_set): Perform code translation here rather than
+ depending on the caller to do so.
+
+ * src/symlist.h (struct symbol_list): Correct some documentation typos.
+ * src/scan-gram.h (gram_last_string): Remove declaration.
+ * src/scan-gram.l (last_string): Declare it static.
+
+2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Encapsulate code properties and related functionality for the various
+ destructors, printers, and actions into a code_props structure and
+ interface. This patch merely implements code_props in scan-code.h and
+ scan-code.l. Future patches will rewrite other modules to use it.
+ Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
+ * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
+ consistently initialize const structs that have an empty location
+ field.
+ * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
+ to ensure consistency.
+ * src/scan-code.h (code_props): New structure.
+ (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
+ function, macro, and const global variable for initializing a
+ code_props with no code.
+ (code_props_plain_init, code_props_symbol_action_init,
+ code_props_rule_action_init, code_props_translate_code): The rest of
+ the new code_props functional interface. Among other things, the init
+ functions set the code_props kind field so that
+ code_props_translate_code will know whether to behave like
+ translate_symbol_action, translate_rule_action, or translate_code.
+ These old translate functions must remain until all other modules are
+ updated to use the new code_props interface.
+ (code_scanner_last_string_free): New function similar to
+ gram_scanner_last_string_free.
+ (code_scanner_free): Add documentation.
+ * src/scan-code.l: Implement the new interface.
+ (code_lex): Make it static, add a code_props* argument, and remove the
+ rule argument.
+ (last_string): New static global similar to the one in scan-gram.l.
+ (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
+ instead of rule.
+ (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
+ code_props since Bison may one day use this information for destructors
+ and printers.
+ (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
+ (handle_action_dollar): Use symbol_list_n_get and set used flag
+ directly since symbol_list_n_used_set is removed.
+ (translate_action): Add a code_props* argument and remove the rule,
+ action, and location arguments. Pass the code_props* on to code_lex.
+ (translate_rule_action, translate_symbol_action, translate_code):
+ Rewrite as wrappers around the new code_props interface.
+ * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
+ it would eventually need to break the encapsulation of code_props.
+
+2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * etc/.cvsignore: New.
+
+2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Add maintainer-push-check to run maintainer-check using push parsing in
+ place of pull parsing where available.
+ * Makefile.am (maintainer-push-check): New.
+ * data/bison.m4 (b4_use_push_for_pull_if): New.
+ * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
+ appropriately based on their existing values.
+ (yypush_parse): Don't print push-parser-specific diagnostics if push
+ parsing is being used in place of pull parsing.
+ * data/yacc.c: If push parsing should replace pull parsing, redirect to
+ push.c.
+ * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
+ variable, and insert b4_use_push_for_pull_flag into muscles.
+ * tests/Makefile.am (maintainer-push-check): New.
+
+2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
+ (whether successful or failed) so that yypush_parse can be invoked
+ again to start a new parse using the same yypstate.
+ * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
+ check multiple yypull_parse invocations on the same yypstate. For pull
+ mode, extend to check multiple yyparse invocations.
+ (Exploding the Stack Size with Alloca): Extend to try with
+ %push-pull-parser.
+ (Exploding the Stack Size with Malloc): Likewise.
+
+ * tests/calc.at (Simple LALR Calculator): Don't specify
+ %skeleton "push.c" since %push-pull-parser implies that now.
+ * tests/headers.at (export YYLTYPE): Don't check for the push
+ declarations. Otherwise, this test case can't be used to see if push
+ mode can truly emulate pull mode.
+ * tests/input.at (Torturing the Scanner): Likewise.
+ * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
+ (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
+ AT_YACC_IF, which now includes the case of push mode since %skeleton
+ need not be used for push mode. This will be more intuitive once
+ push.c is renamed to yacc.c.
+
+2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ For push mode, convert yyparse from a macro to a function, invoke yylex
+ instead of passing a yylexp argument to yypull_parse, and don't
+ generate yypull_parse or yyparse unless %push-pull-parser is declared.
+ Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
+ * data/bison.m4 (b4_pull_if): New.
+ * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
+ * data/push.c: Improve M4 quoting a little.
+ (b4_generate_macro_args, b4_parenthesize): Remove.
+ (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
+ any time a pull parser is requested.
+ Don't #define this as a wrapper around yypull_parse. Instead, when
+ both push and pull are requested, make it a function that does that
+ same thing.
+ (yypull_parse): If there's a b4_prefix, #define this to
+ b4_prefix[pull_parse] when both push and pull are requested.
+ Don't define this as a function unless both push and pull are
+ requested.
+ Remove the yylexp argument and hard-code yylex invocation instead.
+ * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
+ %push-parser.
+ * src/getargs.c (pull_parser): New global initialized to true.
+ * getargs.h (pull_parser): extern it.
+ * src/output.c (prepare): Insert pull_flag muscle.
+ * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
+ (prologue_declaration): Set both push_parser and pull_parser = true for
+ %push-pull-parser. Set push_parser = true and pull_parser = false for
+ %push-parser.
+ * src/scan-gram.l: Don't accept %push_parser as an alternative to
+ %push-parser since there's no backward-compatibility concern here.
+ Scan %push-pull-parser.
+ * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
+ instead of %push-parser.
+ * tests/headers.at (export YYLTYPE): Make yylex static, and don't
+ prototype it in the module that calls yyparse.
+ * tests/input.at (Torturing the Scanner): Likewise.
+ * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
+
+2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Update etc/bench.pl. Optimize push mode a little (the yyn change
+ deserves most of the credit).
+ * Makefile.am (SUBDIRS): Add etc subdirectory.
+ * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
+ * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
+ yytoken, yyval, and yyloc declarations to...
+ (yyparse or yypush_parse): ... here to improve performance. For
+ yypush_parse invocations after the first, be sure to assign yyn its old
+ value again.
+ (yypstate_new): Don't bother initializing the yyresult field since the
+ initial value isn't used.
+ (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
+ remove the #define that, in push mode, set it to yyps->NAME.
+ * etc/Makefile.am: New.
+ * etc/bench.pl: Remove and build it instead from...
+ * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
+ "tests/bison" from the build directory by default rather than just
+ invoking "bison" from $PATH.
+ (calc_grammar): Update push parser code: don't declare yylval globally,
+ don't define yyparse_wrapper, and don't #define yyparse.
+ (bench_grammar): Update to check all working combinations of yacc.c,
+ push.c, impure, pure, pull, and push.
+
+2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ For push mode, add pull wrappers around yypush_parse.
+ * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
+ (yypull_parse): New function wrapping yypush_parse.
+ (yyparse): New #define wrapping yypull_parse.
+ * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
+ is declared.
+ * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
+ prototype yylex in the module that calls yyparse, and don't prototype
+ yyparse there. Otherwise, the yyparse expansion won't compile.
+ * tests/input.at (Torturing the Scanner): Likewise.
+
+2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Enable push parsers to operate in impure mode. Thus, %push-parser no
+ longer implies %pure-parser. The point of this change is to move
+ towards being able to test the push parser code by running the entire
+ test suite as if %push-parser had been declared.
+ * data/push.c (yypush_parse): For impure mode, remove the
+ yypushed_char, yypushed_val, and yypushed_loc arguments.
+ Instead, declare these as local variables initialized to the global
+ yychar, yylval, and yylloc.
+ For the first yypush_parse invocation only, restore the initial values
+ of these global variables when it's time to read a token since they
+ have been overwritten.
+ * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
+ %push-parser.
+ * tests/calc.at (Simple LALR(1) Calculator): Always declare
+ %pure-parser along with %push-parser since this test case was designed
+ for pure push parsers.
+ * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
+ (AT_YACC_OR_PUSH_IF): New.
+ (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
+ add a note that it's still wrong for some cases (as it has been for a
+ while).
+ (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
+ %push-parser no longer implies %pure-parser.
+
+2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Remove some unnecessary differences between the pull parser code and
+ the push parser code. This patch enables yynerrs in push mode.
+ * data/push.c: Reformat M4 a little.
+ (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
+ (b4_declare_scanner_communication_variables): Don't omit yynerrs just
+ because push mode is on. Instead, if pure mode is on, move yynerrs
+ to...
+ (b4_declare_parser_state_variables): ... here.
+ (yynerrs, yyerror_range): For push mode, #define each NAME in this list
+ to yyps->NAME so it can be used in yypush_parse.
+ (yypush_parse): Don't omit uses of yynerrs in push mode.
+
+2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix bug such that the first pushed token's value and location are
+ sometimes overwritten (sometimes by %initial-action) before being used.
+ * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
+ yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
+ For the first yypush_parse invocation, initialize yychar to YYEMPTY to
+ more closely mimic the pull parser logic.
+ Don't copy the pushed token to yychar, yylval, and yylloc until it's
+ time to read a token, which is after any initialization of yylval and
+ yylloc.
+ (gottoken): Rename label to...
+ (yyread_pushed_token): ... for clarity and to avoid infringing on the
+ user namespace.
+
+2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Rearrange initialization of the parser state variables so that the
+ skeleton doesn't have to have a copy for pull mode and another for push
+ mode. This patch also fixes at least a bug such that yylloc was not
+ initialized (with b4_location_initial_line and
+ b4_location_initial_column) upon calling yypush_parse. However, that
+ initialization now overwrites the first token's location;
+ %initial-action assigning @$ already did the same thing, and both bugs
+ will be fixed in a later patch.
+ * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
+ (b4_declare_parser_state_variables): Remove initialization of yytoken,
+ yyss, yyvs, yyls, and yystacksize.
+ (yypstate_new): Remove initialization of some yypstate fields: yystate,
+ yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
+ yylsp.
+ (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
+ yyps->NAME so it can be used in yypush_parse.
+ (yyparse or yypush_parse): For yypush_parse, don't print the
+ "Starting parse" diagnostic for invocations after the first.
+ Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
+ yypush_parse, only do it for the first invocation.
+ Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
+ initialization to occur in yypush_parse but only on the first
+ invocation.
+
+2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/push.c: Add CPP guards around push parser declarations in both
+ the header and the code file.
+ In the code file, move the push parser declarations to the same place
+ they appear in the header file.
+ Clean up the M4 some, especially the inconsistent underquoting in
+ some b4_c_function_def and b4_c_function_decl uses.
+
+2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Encapsulate the push parser state variables into an M4 macro so the
+ push skeleton doesn't have to list them again for pull mode's yyparse.
+ For push mode, remove yypush_parse's local equivalents of these
+ variables to eliminate unnecessary copying between the two sets at
+ run-time. This patch also fixes at least a bug related to multiple
+ %initial-action invocations in push mode.
+ * data/push.c (b4_declare_parser_variables): Rename to...
+ (b4_declare_scanner_communication_variables): ... this for clarity and
+ update both uses.
+ (b4_declare_yyparse_variables): Remove and move its contents to the one
+ spot where it was invoked.
+ (b4_declare_parser_state_variables): New macro containing the parser
+ state variables required by push mode.
+ (struct yypstate): Replace all fields but yynew with
+ b4_declare_parser_state_variables.
+ (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
+ yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
+ each NAME in this list to yyps->NAME so it can be used in yypush_parse.
+ (yyparse or yypush_parse): For yyparse in pull mode, replace local
+ parser state variable declarations with
+ b4_declare_parser_state_variables.
+ Don't initialize parser state variables when calling yypush_parse since
+ yypstate_new already does that.
+ Invoke the user's initial action only upon the first yypush_parse
+ invocation.
+ Remove all code that copies between the local parser state variables
+ and the yypstate.

+ since it no longer has the same name as the existing argument.

+
+ * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
+ `bison ', use m4_index instead of m4_substr since chopping up a string
+ containing M4-special characters causes problems here.
+
+ Fix a couple of bugs related to special characters in user-specified
+ file names, and make it easier for skeletons to compute output file
+ names with the same file name prefix as Bison-computed output file
+ names.
+ * data/glr.cc, data/push.c, data/yacc.c: In @output, use
+ b4_parser_file_name and b4_spec_defines_file instead of
+ @output_parser_name@ and @output_header_name@, which are now redundant.
+ * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
+ b4_parser_file_name, b4_spec_defines_file, and the new
+ @basename(FILENAME@) instead of @output_parser_name@ and
+ @output_header_name@, which inappropriately escaped the file names as

+ * src/files.c (all_but_ext): Remove static qualifier.
+ (compute_output_file_names): Move `free (all_but_ext)' to...

+ characters are escaped properly.
+ * src/output.c (prepare): Define muscle file_name_all_but_ext as
+ all_but_ext.
+ For pkgdatadir muscle, maintain previous functionality by using
+ MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
+ is that b4_pkgdatadir is used inside m4_include in the skeletons, so
+ digraphs would never be expanded. Hopefully no one has M4-special
+ characters in his Bison installation path.
+ * src/scan-skel.l: Don't parse @output_header_name@ and
+ @output_parser_name@ anymore since they're now redundant.
+ In @output, use decode_at_digraphs.

+
+ Split the default %destructor/%printer into two kinds: <*> and <!>.
+ Discussed starting at

+ * NEWS (2.3a+): Mention.
+ * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the
+ previous change today related to mid-rules.
+ (Table of Symbols): Remove %symbol-default and add <*> and <!>.
+ * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): Remove.
+ (TYPE_TAG_ANY): Add as <*>.
+ (TYPE_TAG_NONE): Add as <!>.
+ (generic_symlist_item): Remove RHS for %symbol-default and add RHS's
+ for <*> and <!>.
+ * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove.
+ (TYPE_TAG_ANY, TYPE_TAG_NONE): Add.
+ * src/symlist.c (symbol_list_default_new): Split into tagged and
+ tagless versions.
+ (symbol_list_destructor_set, symbol_list_printer_set): Split
+ SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and
+ SYMLIST_DEFAULT_TAGLESS.
+ * src/symlist.h: Update symbol_list_default*_new prototypes.
+ (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
+ SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
+ * src/symtab.c (default_destructor, default_destructor_location,
+ default_printer, default_printer_location): Split each into tagged and
+ tagless versions.
+ (symbol_destructor_get, symbol_destructor_location_get,
+ symbol_printer_get, symbol_printer_location_get): Implement tagged
+ default and tagless default cases.
+ (default_destructor_set, default_printer_set): Split each into tagged
+ and tagless versions.
+ * src/symtab.h: Update prototypes.
+ * tests/actions.at (Default %printer and %destructor): Rename to...

+
+2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>

+
+ Warn about unset midrule $$ if the corresponding $n is used.
+ * src/reader.c (symbol_should_be_used): Check midrule parent rule for
+ $n usage.
+ (packgram): Before invoking grammar_rule_check on any rule, make sure

+ Otherwise, checking that a midrule's $$ is set will not always work
+ properly because the midrule check must forward-reference the midrule's
+ parent rule.
+ * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
+ warning.
+
+2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>

+
+2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Similar to the recently removed %before-header, add %code-top as the
+ alternative to the pre-prologue. Mentioned at

+ sticks with the automake default in generating dependencies.
+
+2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
+

+
+ 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap (symlink_to_gnulib): New function.
+ (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
+ to copies-of-gnulib.
+ (cp_mark_as_generated, slurp, gnulib_files):
+ Avoid making a copy if it's the same as the old version.
+ (gnulib_files): Add support for this variable (used by Bison).
+
+2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/getargs.c (usage): Rework to use conventions similar to
+ coreutils, to make translation a bit easier and the code a bit
+ smaller. Problem reported by Tim Van Holder.
+
+2006-09-15 Paul Eggert <eggert@cs.ucla.edu>

+ * src/Makefile.am (DEFS): Remove, since configmake does this for us.
+ (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
+ * src/system.h: Include inttypes.h unconditionally, now that we
+ use the inttypes module. Don't bother to include stdint.h, since

+ * src/main.c: Likewise.
+ * src/output.c: Likewise.

+
+
+ Port to GCC 2.95. First two problems reported by Michael Deutschmann in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
+
+ * src/parse-gram.y (symbol_declaration): Don't put statements
+ before declarations; it's not portable to C89.
+ * src/scan-code.l (handle_action_at): Likewise.
+
+ * src/scan-code.l: Always initialize braces_level; the old code
+ left it uninitialized and therefore had undefined behavior.
+
+ Don't attempt to redefine 'assert', since it runs afoul of
+ systems where standard headers (mistakenly) include <assert.h>.
+ Instead, define and use our own alternative, called 'aver'.
+ * src/reader.c: Don't include assert.h, since we no longer
+ use assert.
+ * src/scan-code.l: Likewise.
+ * src/system.h (assert): Remove, replacing with....
+ (aver): New function, taking a bool arg. All uses changed.
+ * src/tables.c (pack_vector): Ensure that aver arg is bool,

+ * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
+ list of removed lines from the traces observed.
+ (AT_CHECK_CALC_LALR): Added push parser tests.
+
+2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Version 2.3a.
+ * configure.ac (AC_INIT): Likewise.
+
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
+ "#define YYSTYPE int" that caused "make maintainer-check" to fail
+ due to header ordering dependencies. I don't know why the #define
+ was there.
+
+ Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
+ runtime cost when YYDEBUG is not defined, and so that some tests
+ that used to fail now work. Problem and initial suggestion by
+ Paolo Bonzini.
+ * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
+ * data/glr.cc (b4_parser_class_name):
+ Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.

+ (debug_stream, set_debug_stream, debug_level, set_debug_level):
+ Define only if YYDEBUG.
+ * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
+ set_debug_level.
+ * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
+ * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
+ AT_CHECK_CALC_GLR_CC that are working now.
+
+2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
+ We don't need them in glr.cc, and glr.c defines them.
+ Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
+ assumes that defining it to anything is the same as defining
+ it to 1. Problem reported by Paolo Bonzini.
+
+2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
+
+ * data/c.m4 (b4_null, b4_case): Define.

+
+ * data/glr.c (b4_shared_declarations): Put start-header first,

+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
+ that depend on location.hh after, not before, Bison decls, since
+ we now include location.hh after the first user prologue.
+
+ * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
+ Sander Brandenburg in

+ Also, fix minor white space and comment issues.
+ (Prologue): Mention that it's better to define feature-test macros

+
+ * README-cvs: Fix typo: "&" should be "&&". Problem reported

+ * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
+ * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):

+ * src/symtab.c, src/symtab.h: Extend with a table that associates
+ semantic types with their %destructor's and %printer's.
+ (semantic_type_from_uniqstr, semantic_type_get,

+ composing the public interface of that table.
+ (symbol_destructor_get, symbol_destructor_location_get,

+ * tests/actions.at (Per-type %printer and %destructor): New test case.
+ * tests/input.at (Default %printer and %destructor redeclared):

+
+ Require default %destructor/%printer to be declared using

+ new per-type %destructor/%printer. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
+ * NEWS (2.3+): Add %symbol-default to example.
+ * bison.texinfo (Freeing Discarded Symbols): Likewise.
+ (Table of Symbols): Add entry for %symbol-default.
+ * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
+ (generic_symlist, generic_symlist_item): New nonterminals for creating
+ a list in which each item is a symbol, semantic type, or

+ (grammar_declaration): Use generic_symlist in %destructor and %printer
+ declarations instead of symbols.1 or an empty list.
+ (symbol_declaration, precedence_declaration, symbols.1): Update actions
+ for changes to symbol_list.

+ * src/symlist.c, src/symlist.h: Extend such that a list node may
+ represent a semantic type or a %symbol-default in addition to just an
+ ordinary symbol. Add switched functions for setting %destructor's and
+ %printer's.
+ * tests/actions.at, tests/input.at: Add %symbol-default to all default
+ %destructor/%printer declarations.
+
+2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Whether the default %destructor/%printer applies to a particular symbol
+ isn't a question of whether the user *declares* that symbol (in %token,
+ for example). It's a question of whether the user by any means
+ *defines* the symbol at all (by simply using a char token, for
+ example). $end is defined by Bison whereas any other token with token
+ number 0 is defined by the user. The error token is always defined by
+ Bison regardless of whether the user declares it with %token, but we
+ may one day let the user define error as a nonterminal instead.
+ * NEWS (2.3+): Say "user-defined" instead of "user-declared".
+ * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
+ the meaning of "user-defined".
+ * tests/actions.at (Default %printer and %destructor for user-declared
+ end token): Rename to...
+ (Default %printer and %destructor for user-defined end token): ...
+ this.
+
+ * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
+ computation of whether to apply the default, don't maintain a list of
+ every Bison-defined symbol. Instead, just check for a first character
+ of '$', which a user symbol cannot have, and check for the error token.
+
+2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't apply the default %destructor or %printer to the error token,
+ $undefined, or $accept. This change fits the general rule that the
+ default %destructor and %printer are only for user-declared symbols,
+ and it solves several difficulties that are described in the new test
+ cases listed below.
+ * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
+ * tests/actions.at (Default %printer and %destructor are not for error
+ or $undefined, Default %printer and %destructor are not for $accept):
+ New test cases.
+
+2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Allow %start after the first rule.
+ * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
+ when parsing the first rule.
+ (check_and_convert_grammar): Search for it here after all grammar
+ declarations have been parsed. Skip midrules, which have dummy LHS
+ nonterminals.
+ * src/symtab.c (symbol_is_dummy): New function.
+ * src/symtab.h (symbol_is_dummy): Declare it.
+ * tests/input.at (%start after first rule): New test.
+
+2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Redo some of the previous commit: add back the ability to use
+ non-aliased/undeclared string literals since it might be useful to
+ those declaring %token-table.
+ * src/reader.c (check_and_convert_grammar): Undo changes in previous
+ commit: don't worry about complaints from symbols_pack.
+ * src/symtab.c (symbol_new, symbol_class_set,
+ symbol_check_alias_consistency): Undo changes in previous commit: count
+ each string literal as a new symbol and token, assign it a symbol
+ number, and don't complain about non-aliased string literals.
+ (symbols_pack): Since symbol_make_alias still does not decrement symbol
+ and token counts but does still set aliased tokens to the same number,
+ symbol_pack_processor now leaves empty slots in the symbols array.
+ Remove those slots.
+ * tests/regression.at (Undeclared string literal): Remove test case
+ added in previous commit since non-aliased string literals are allowed
+ again.
+ (Characters Escapes, Web2c Actions): Undo changes in previous commit:
+ remove unnecessary string literal declarations.
+ * tests/sets.at (Firsts): Likewise.
+
+2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't allow an undeclared string literal, but allow a string literal to
+ be used before its declaration.
+ * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
+ symbols_pack complained.
+ * src/symtab.c (symbol_new): Don't count a string literal as a new
+ symbol.
+ (symbol_class_set): Don't count a string literal as a new token, and
+ don't assign it a symbol number since symbol_make_alias does that.
+ (symbol_make_alias): It's not necessary to decrement the symbol and
+ token counts anymore. Don't assume that an alias declaration occurs
+ before any uses of the identifier or string, and thus don't assert that
+ one of them has the highest symbol number so far.
+ (symbol_check_alias_consistency): Complain if there's a string literal
+ that wasn't declared as an alias.
+ (symbols_pack): Bail if symbol_check_alias_consistency failed since
+ symbol_pack asserts that every token has been assigned a symbol number
+ although undeclared string literals have not.
+ * tests/regression.at (String alias declared after use, Undeclared
+ string literal): New test cases.
+ (Characters Escapes, Web2c Actions): Declare string literals as

+ * tests/sets.at (Firsts): Likewise.

+2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ In the grammar scanner, STRING_FINISH unclosed constructs and return
+ them to the parser in order to improve error messages.
+ * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,

+ * tests/input.at (Unclosed constructs): New test case.
+ * tests/regression.at (Invalid inputs): Update now that unclosed %{ is

+
+ * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
+ unused global.
+
+2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Handle string aliases for character tokens correctly.
+ * src/symtab.c (symbol_user_token_number_set): If the token has an
+ alias, check and set its alias's user token number instead of its own,
+ which is set to indicate the alias. Previously, every occurrence of
+ the character token in the grammar overwrote that alias indicator with
+ the character code.
+ * tests/input.at (String aliases for character tokens): New test.
+
+2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
+
+2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
+ to prevent failures when building on older platforms.
+ Check for autopoint failure.
+ Set XGETTEXT_OPTIONS to values that check for C format strings,
+ so that translators are warned about them (this also helps
+ prevent core dumps).
+
+ * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
+ function, since it simplifies our code a bit.
+
+ * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
+ rather than -W, so we don't get bogus warnings about sign comparisons.
+ Add -Wpointer-arith, since that warning is useful (it reports code
+ that does not conform to C89 and that some compilers reject).
+ * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
+ since it's no longer needed.
+
+2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up scanners a bit.
+ * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
+ definitions so gcc won't warn when obstack_for_string is unused.
+ * src/scan-code.l: config.h and system.h are already #include'd by
+ scan-code-c.c, so get rid of them here.
+ * src/scan-gram.l: Likewise.
+ * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
+ definitions rather than duplicating the rest of it.
+ * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
+
+2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Suppress signed/unsigned comparison warnings for yycheck.
+ * data/c.m4 (b4_safest_int_type): New macro.
+ * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
+ a signed int type, cast it to b4_safest_int_type first.
+ * data/yacc.c: Likewise.
+ (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
+ also overwritten.
+
+2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
+
+ * doc/bison.texinfo: Fix some typos.
+
+2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
+
+ * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
+ po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
+
+ * bootstrap (gnulib_tool): Stop using --assume-autoconf;
+ the latest gnulib does this a different way.
+ (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
+ translation was patched, so stop omitting it.
+
+2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Enable declaration of default %printer/%destructor. Make the parser
+ use these for all user-declared grammar symbols for which the user does
+ not declare a specific %printer/%destructor. Thus, the parser uses it
+ for token 0 if the user declares it but not if Bison generates it as
+ $end. Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,

+ * NEWS (2.3+): Mention.
+ * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
+ declare a %destructor for a mid-rule's semantic value. It's just
+ impossible to declare one specific to it.
+ (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
+ code. Describe default %destructor form.
+ * src/parse-gram.y (grammar_declaration): Parse default
+ %printer/%destructor declarations.
+ * src/output.c (symbol_destructors_output): Use symbol_destructor_get
+ and symbol_destructor_location_get rather than accessing the destructor
+ and destructor_location members of struct symbol.
+ (symbol_printers_output): Likewise but for %printer's.
+ * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
+ again.
+ * src/symtab.c (default_destructor, default_destructor_location,
+ default_printer, default_printer_location): New static global
+ variables to record the default %destructor and %printer.
+ (symbol_destructor_get, symbol_destructor_location_get,
+ symbol_printer_get, symbol_printer_location_get): New functions to
+ compute the appropriate %destructor and %printer for a symbol.
+ (default_destructor_set, default_printer_set): New functions to set the
+ default %destructor and %printer.
+ * src/symtab.h: Prototype all those new functions.
+ * tests/actions.at (Default %printer and %destructor): New test to
+ check that the right %printer and %destructor are called, that they're
+ not called for $end, and that $$ and @$ work correctly.
+ (Default %printer and %destructor for user-declared end token): New
+ test to check that the default %printer and %destructor are called for
+ a user-declared end token.
+ * tests/input.at (Default %printer and %destructor redeclared, Unused
+ values with default %destructor): New tests to check related grammar
+ warnings and errors.
+
+2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up handling of %destructor for the end token (token 0).
+ Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
+ and
+ <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
+
+ Make the skeletons consistent in how they pop the end token and invoke
+ its %destructor.
+ * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
+ state, which has token number 0, since this would invoke the
+ %destructor for the end token.
+ * data/lalr1.cc (yy::parser::parse): Don't check for the final state
+ until after shifting the end token, or else it won't be popped.
+ * data/yacc.c (yyparse): Likewise.
+
+ * data/glr.c (yyparse): Clear the lookahead after shifting it even when
+ it's the end token. Upon termination, destroy an unshifted lookahead
+ even when it's the end token.
+ * data/lalr1.cc (yy::parser::parse): Likewise.
+ * data/yacc.c (yyparse): Likewise.
+
+ * src/reader.c (packgram): Don't check rule 0. This suppresses unused
+ value warnings for the end token when the user gives the end token a
+ %destructor.
+
+ * tests/actions.at (Printers and Destructors): Test all the above.
+
+2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ Update to latest gnulib and gettext versions.
+ * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
+ Add fopen-safer.
+ (gnulib_files): Add m4/warning.m4. Don't worry about files
+ overwritten by autopoint.
+ Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
+ Suppress "id", "ms", "tr" translations for now, since gettext 0.15
+ rejects them.
+ Don't use autoreconf; instead, invoke autopoint etc. by hand,
+ so that we can remove the intl files at a better time.
+ (intl_files_to_remove): Remove aclocal.m4, since it gets
+ rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
+ m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
+ m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
+ Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
+ Remove datarootdir hack; no longer needed.
+ * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
+ (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
+ * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
+ strdup.h.
+ * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
+ * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
+
+2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap: Adjust to today's change to gnulib-tool by invoking
+ it with --assume-autoconf='latest-stable'.
+
+2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at

+ YYSTYPE' and `{'.
+ * src/muscle_tab.h (muscle_grow): Replace the header comments with
+ those from muscle_tab.c since the old ones are misleading.
+
+2006-07-13 Akim Demaille <akim@epita.fr>
+
+ Support %define "KEY" {VALUE}.

+
+2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'

+ compiler reported by Hung Nguyen in
+ <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.

+
+2006-07-09 Akim Demaille <akim@lrde.epita.fr>

+
+2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"

+ (yy_stack_print): Don't assume that yytype_int16 promotes to int;
+ this was never guaranteed, and now that we're using gnulib stdint,

+
+2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_basename): Simplify a bit, since we don't

+ anyway).
+
+ Adjust to Autoconf 2.60 and today's gnulib.
+ * bootstrap (gnulib_modules): Add stdint.
+ Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
+ no longer copies it.
+ (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
+ since stdint needs the former and wcwidth (which is now required
+ by mbswidth) needs the latter.
+ Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
+ work around a compatibility glitch between gettext 0.14.6 and
+ Autoconf 2.60.
+ * configure.ac (AC_PREREQ): Require Autoconf 2.60.
+ Do not check for uintptr_t, since new stdint module does the right

+
+ Don't miss %merge result type warnings just because the LHS types are

+ * src/reader.c (get_merge_function): Don't set the merger type yet.

+ Don't mistake the type of $$ in a midrule to be that of its parent

+ * src/reader.c (grammar_current_rule_end): Don't invoke
+ grammar_rule_check yet since not all symbol declarations may have been
+ parsed yet.
+ (grammar_midrule_action): Likewise.
+ Don't record whether the midrule's $$ has been used yet since actions
+ haven't been translated yet.
+ Record the midrule's parent rule and its RHS index within the parent
+ rule.
+ (grammar_current_rule_action_append): Don't translate the action yet
+ since not all symbol declarations may have been parsed yet and, thus,
+ warnings about types for $$, $n, @$, and @n can't be reported yet.
+ (packgram): Translate the action and invoke grammar_rule_check now that
+ all symbol declarations have been parsed.
+ * src/scan-code.l (handle_action_dollar): Now that this is invoked
+ after parsing the entire grammar file, the symbol list here in the case
+ of a midrule is actually the midrule's empty RHS, so reference its
+ parent rule's RHS where necessary.
+ On the other hand, now that you can already know it's a midrule, you
+ aren't forced to think $$ has the same type as its parent rule's $$.
+ (handle_action_at): In the case of a midrule, reference the parent rule
+ where necessary.
+ * src/symlist.c (symbol_list_new): Initialize new midrule-related
+ members.
+ (symbol_list_length): Now that this is invoked after all rules have
+ been parsed, a NULL symbol (rather than a NULL symbol list node)
+ terminates a rule. symbol_list_print already does this correctly.
+ * src/symlist.h (symbol_list.midrule_parent_rule,
+ symbol_list.midrule_parent_rhs_index): New members so that midrules can
+ remember their relationships with their parents.
+ * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
+ fixed by the above patch.
+ (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
+ implementing...
+ (Unused values): ... this old test case and...

+2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix bug that mistakes braced code in a declaration in the rules section
+ to be a rule action. Mentioned at

+ * src/scan-gram.l: Move midrule action detection from the start of the

+ action. For readability, use $2 and @2 rather than the equivalent
+ global variables.
+ * tests/regression.at (Braced code in declaration in rules section):
+ New test to catch the error fixed by the above patch.
+
+ Work on code readability some.
+ * src/scan-code.l (current_rule): Get rid of this misleading and
+ redundant declaration: it's actually extern'ed in reader.h.
+ (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
+ translate_action): Add a rule argument and use it instead of the global
+ current_rule.
+ (translate_rule_action): This already receives current_rule through an
+ argument, so pass it on to translate_action instead of assigning
+ current_rule to current_rule.
+ (translate_symbol_action, translate_code): Pass rule = NULL to

+
+2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Between Bison releases, manually append `+' to the previous Bison
+ release number, and use that as a signal to automatically print the
+ ChangeLog's CVS Id keyword from --version. Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
+ * ChangeLog: Add Id header.
+ * configure.ac (AC_INIT): Append `+' to `2.3'.
+ * src/.cvsignore: Add revision.c.
+ * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
+ (BUILT_SOURCES): Add revision.c.
+ (revision.c): New target rule. This file defines a new global variable
+ named revision. It initializes it with either the Id from ChangeLog
+ or, if VERSION doesn't contain `+', with the empty string.
+ * src/getargs.c (version): Print the value of revision.

+
+ * data/glr.c (YYRECOVERING): Define to be a function-like macro
+ with no arguments, not as an object-like macro. This is for
+ compatibility with data/yacc.c. Problem reported by John P. Hartmann in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.

+
+2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
+ shell, not within 'make', so that 'make' by an ordinary builder
+ (using GNU make) does not worry about configuring gzip. This also
+ works around a bug reported independently by Keith Thompson and by
+ Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
+ stderr rather than stdout, messing up the build logs.
+
+2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
+ to make sure that YYID will never be unused. This fixes a 'make
+ maintainer-check' failure caused by the recent changes to the 'Trivial
+ grammars' test case, which caused g++ 4.1.0 to complain that YYID was
+ not used.
+ * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
+
+2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
+ state before an empty RHS is always resolved here. Only the location
+ of that state is guaranteed to be resolved, and that's enough. This
+ fixes the remaining bug reported by Derek M. Jones in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+ * tests/glr-regression.at (Uninitialized location when reporting
+ ambiguity): Test the above case.
+ Also, the embedded comments in this test case claim it checks the case
+ of an empty RHS that has inherited the initial location. However, the
+ corresponding LHS was already resolved, so yyresolveLocations didn't
+ actually have reason to modify it. Fix this by forcing
+ nondeterministic operation at the beginning of the parse.
+
+2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_yy_symbol_print_generate):
+ (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
+ 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
+ of the bugs reported today by Derek M Jones in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+ * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
+ defined to be a type name without parens or brackets.
+ (Location Type): Similarly for YYLTYPE.
+ * tests/regression.at (Trivial grammars): Put in a test for this
+ bug that will be caught by 'make maintainer-check' (though not,
+ alas, by 'make check' unless your compiler is picky).
+
+2006-05-19 Paul Eggert <eggert@cs.ucla.edu>

+ M. Jones in
+ <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
+ (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
+ to the user. Reported for yyreportTree by Derek M. Jones later in the
+ same thread.
+ * THANKS: Add Derek M. Jones.
+ Update my email address.
+ Fix typo in Steve Murphy's name.
+
+2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
+ checking against YYLAST that caused the parser to miss a potential
+ alternative in its diagnostic.
+ Problem reported by Maria Jose Moron Fernandez in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.

+
+ * data/yacc.c (yytnamerr): Fix typo: local var should be of type
+ YYSIZE_T, not size_t.

+
+2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_copyright): Put the special exception for Bison

+
+ Apply --prefix to C++ skeletons too: they change the namespace.

+
+2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't leak semantic values for parent RHS when a user action cuts the

+ for leaked parent RHS values.
+ * data/glr.c (yydestroyGLRState): In debugging output, distinguish
+ between an unresolved state (non-empty chain of semantic options) and

+ (yyresolveStates): Document the interface. Move all manipulation of a
+ successfully or unsuccessfully resolved yyGLRState to...
+ (yyresolveValue): ... here so that yyresolveValue always leaves a
+ yyGLRState with consistent data and thus is easier to understand.
+ Remove the yyvalp and yylocp parameters since they are always just
+ taken from the yys parameter. When reporting a discarded merged value
+ in debugging output, note that it is incompletely merged. Document the
+ interface.
+ (yyresolveAction): If resolving any of the RHS states fails, destroy
+ them all rather than leaking them. Thus, as long as user actions are
+ written to clean up the RHS correctly, yyresolveAction always cleans up
+ the RHS of a semantic option. Document the interface.

+
+ During deterministic GLR operation, user actions should be able to

+
+ Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I

+
+ Use unlocked I/O for a minor performance improvement on hosts like
+ GNU/Linux and Solaris that support unlocked I/O. The basic idea
+ is to use the gnlib unlocked-io module, and to prefer putc and
+ puts to printf when either will work (since the latter doesn't
+ come in an unlocked flavor).
+ * bootstrap (gnulib_modules): Add unlocked-io.
+ * data/c.m4 (yysymprint): Prefer puts and putc to printf.

+ * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.

+ All callers changed.
+ * tests/glr-regression-at (make_value): Args are const pointers now,

+
+ * tests/regression.at (Token definitions): Don't rely on
+ AT_PARSER_CHECK for data that contains backslashes. It currently
+ uses 'echo', and 'echo' isn't portable if its argument contains
+ backslashes. Problem found on OpenBSD 3.4. Also, do not assume
+ that the byte '\0xff' is not printable in the C locale; it is,
+ under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
+ not printable, so use '\0x81' to test.
+
+ * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent

+ (alpha, beta, major): Depend on news-date-check.
+ Make the upload commands.

+ (output_skeleton):
+ Indent calls to "error" to pacify "make maintainer-distcheck".
+ * src/print_graph.c: Don't include <obstack.h>, as system.h does this.

+
+2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac: Update version number.
+
+ * Makefile.am (SUBDIRS): Add examples; somehow this got removed
+ accidentally.
+ * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
+ autogenerated by the maintainer.
+ * examples/calc++/.cvsignore: Add *.yy.

+
+ * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
+
+ * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
+ from maintainer-distcheck about casting the argument of 'free'.
+
+ * NEWS: Mention recent yytname changes.
+ * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
+
+ * bootstrap: For translations that have not yet been upgraded to
+ the new runtime-po domain, prime the pump by extracting the
+ relevant strings from the obsolete translations. This code can be
+ removed once the bison-runtime domain has been translated by each
+ team.
+
+ * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
+ now that token names are already quoted.
+
+ Fix problem reported by Anthony Heading.
+ * data/glr.c (YYTOKEN_TABLE): New macro.
+ (yytname): Define if YYTOKEN_TABLE.

+
+ * data/glr.c (yytnamerr): New function.
+ (yyreportSyntaxError): Use it to dequote most string literals.

+ (yyerrlab): Use it to decode most string literals.
+ * doc/bison.texinfo (Decl Summary, Calling Convention):
+ Clarify quoting convention of yytname.

+ changes in the parsers as described above.
+ * tests/regression.at (Token definitions, Web2c Actions):
+ Undo most 2005-04-17 change here, too.
+
+2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix more problems reported by twlevo@xs4all.nl.
+ * tests/cxx-type.at: Don't pipe output of ./types through sed to
+ remove trailing spaces. This loses the exit status of ./types,
+ and isn't needed since ./types shouldn't be emitting trailing
+ spaces.
+ * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
+ as the stack isn't valid in that case.
+
+ * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
+ (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
+ (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
+ Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
+ is used.
+ * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
+ (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
+ (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
+ Likewise.
+
+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
+ overly-picky compilers that reject 'char *foo = "bar";'.
+
+ * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
+ to FILE * parameter, not to stderr. This fixes a typo introduced
+ in the 2005-07-12 change.
+
+ * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
+ warnings from GCC 4.
+
+ * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
+ (yyglrShiftDefer, yysplitStack):
+ Remove unused parameters b4_pure_formals. All uses changed.

+2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ Destructor cleanups and regularization among the three skeletons.
+ * NEWS: Document the behavior changes.
+ * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
+ stack before failing, as the cleanup code will do it for us now.
+ * data/lalr1.cc (yyerrlab): Likewise.
+ * data/glr.c (yyparse): Pop everything off the stack before
+ freeing it, so that destructors get called properly.
+ * data/lalr1.cc (yyreturn): Likewise.
+ * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
+ This is more consistent.
+ * doc/bison.texinfo (Destructor Decl): Mention more reasons
+ why destructors might be called. 1.875 -> 2.1.
+ (Destructor Decl, Decl Summary, Table of Symbols):
+ Some English-language cleanups for %destructor.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
+ Add output line for destructor of start symbol.
+ * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
+ because of that same extra output line.
+
+ * NEWS: Document minor wording changes in diagnostics of
+ Bison-generated parsers.
+ * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
+ Remove unused formals. All uses changed.
+ (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
+ (yyparse): Rename yyoverflowlab to yyexhaustedlab.
+ * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
+ Rename yyoverflowab to yyexhaustedlab.
+ When memory exhaustion occurs during syntax-error reporting,
+ report it separately rather than in a single diagnostic; this
+ eases translation.
+ * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
+ (Memory Exhausted): Renamed from Parser Stack Overflow.
+ Revamp wording slightly to prefer "memory exhaustion".
+ * tests/actions.at: "parser stack overflow" -> "memory exhausted".
+
+ * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
+
+ Add i18n support to the GLR skeleton. Partially fix the C++
+ skeleton; a C++ expert needs to finish this. Remove debugging
+ msgids; there's little point to having them translated, since they
+ can be understood only by someone who can read the
+ (English-language) source code.
+
+ Generate runtime-po/bison-runtime.pot automatically, so that we
+ don't have to worry about garbage getting in that file. We'll
+ make sure after the next official release that old msgids don't
+ get lost. See
+ <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
+
+ * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
+ Now auto-generated.
+ * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
+ Fix typos in explanations of the runtime file.
+ * bootstrap: Change gettext keyword from YYI18N to YY_.
+ Use standard Makefile.in.in in runtime-po, since we'll arrange
+ for backward-compatible bison-runtime.po files in a different way.
+ * data/glr.c (YY_): New macro, from yacc.c.
+ (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
+ Translate messages intended for users.
+ (yyreportSyntaxError): Change "virtual memory" to "memory" to match
+ the wording in the other skeletons. We don't know that the memory
+ is virtual.
+ * data/lalr1.cc (YY_): Renamed from _. All uses changed.
+ Use same method that yacc.c uses.
+ Don't translate debugging messages.
+ (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
+ it doesn't work (yet), and requires C++ expertise to fix.
+ * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
+ Move defn to a more logical place, to be consistent with other
+ skeletons.
+ Don't translate debugging messages.
+ Don't assume line numbers fit in unsigned int; use unsigned long fmts.
+ * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
+ to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
+ * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
+
+ Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
+ void, not int.
+ * tests/glr-regression.at (Badly Collapsed GLR States):
+ Likewise.
+ (Improper handling of embedded actions and dollar(-N) in GLR parsers):
+ yylex should return 0 at EOF rather than aborting.
+
+ Improve tests for stack overflow in GLR parser.
+ Problem reported by twlevo@xs4all.nl.
+ * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
+ All uses removed.
+ (yyStackOverflow): Just longjmp, but with value 2 so that caller
+ can handle the problem.
+ (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
+ (yyparse): New local variable yyresult to record the result.
+ Use result of setjmp to set it, rather than storing itinto
+ struct.
+ (yyDone): Remove label.
+ (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
+ to mimic yacc.c. Do not discard lookahead if it's EOF (possible
+ if YYABORT is used).
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
+ yyparse status; put status > 1 into diagnostic.
+ Check that status==2 works.
+ * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
+ Use exit status 3 for failure to open (which shouldn't happen).
+
+2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/conflicts.at (%nonassoc and eof): Don't exit with status
+ 1 on syntax error; just let yyparse do its thing.
+ * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
+ * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
+ (Exploding the Stack Size with Alloca):
+ (Exploding the Stack Size with Malloc):
+ Expect exit status 2, not 1, since the parser is supposed to blow
+ its stack. Problem reported by twlevo@xs4all.nl.
+
+ * data/glr.c (yyparse): Don't assume that the initial calls
+ to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
+ Print a stack-overflow message and fail instead.
+ Initialize the line-number information before creating the stack,
+ so that the stack-overflow message can report line zero safely.
+
+2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix problems reported by twlevo@xs4all.nl.
+ * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
+ (yyuserMerge): Provide a default case if b4_mergers is empty.
+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
+ * tests/glr-regression.at
+ (Improper handling of embedded actions and dollar(-N) in GLR parsers):
+ Add casts to pacify C++ compilers.
+ * tests/glr-regression.at (Improper merging of GLR delayed action
+ sets): Declare yylex before using it.
+ * tests/Makefile.am (maintainer-check-g++): Fix a stray
+ $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
+ test for valgrind; valgrind is independent of g++.
+ (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
+ for compatibility with POSIX 1003.1-2001 (if running coreutils).
+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
+ Use a destructor, so that we can expand the stack. Change
+ YYSTYPE to char * so that we can free it. Cast result of malloc.
+
+2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
+
+ * data/glr.c (yyuserAction): Fix uninitialized variable that caused
+ a valgrind failure. Problem reported by twlevo@xs4all.nl.

+
+ * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:

+
+2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyFail): Drastically simplify; since the format argument
+ never had any % directives, we can simply pass it to yyerror.
+ (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
+ be modified later, as that is the usual style in glr.c.
+ Problems reported by Paul Hilfinger.
+
+ Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
+ and size overflow errors.
+ * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
+ in case the user prolog sets feature-test macros like _GNU_SOURCE.
+ (YYSIZEMAX): New macro.
+ (yystpcpy): New function, taken from yacc.c.
+ (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
+ (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
+ so that we don't have to maintain their signatures.
+ (yyFail): Check for buffer overflow, by using vsnprintf rather
+ than vsprintf. Allocate a bigger buffer if possible.
+ Report an error if buffer allocation fails.
+ (yyStackOverflow): New function.
+ (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
+ the initialization was successful. It might fail if storage was
+ exhausted.
+ (yyexpandGLRStack): Add more checks for storage allocation failure.
+ Use yyStackOverflow to report failures.
+ (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):

+ Don't assume stack number fits in int.
+ (yysplitStack): Check for storage allocation failure.
+ (yysplitStack, yyprocessOneStack): Add pure_formals, so that we

+ (yyresolveValue): Use yybool for boolean.
+ (yyreportSyntaxError): Check for size-calculation overflow.
+ This code is taken from yacc.c.

+
+ * NEWS: Version 2.0a.
+
+ * src/files.c: Include "stdio-safer.h"; this fixes a typo in
+ the previous change.
+
+ Various maintainer cleanups.
+ * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
+ conftest*, for benefit of CVS commands run at the same time as

+ * config/prev-version.txt: Bump from 1.75 to 2.0.
+
+ * bootstrap: Add stdio-safer, unistd-safer modules.

+ fopen-safer.c, stdio-safer.h, unistd-safer.h.
+ * lib/subpipe.c: Include "unistd-safer.h".

+ (yyoverflowlab): Don't call destructor.
+ (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
+ * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,

+
+ Fix some problems reported by twlevo at xs4all.

+2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,

+
+ (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming

+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
+ that column numbers start at column 0, as per GNU Coding
+ Standards, the others tests, and the doc.
+ (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
+ Adjust to the above change (first column is 0).
+ And adjust the location of the "<error>", now covering the whole
+ line.
+
+2004-10-22 Akim Demaille <akim@epita.fr>
+ and Paul Eggert <eggert@cs.ucla.edu>
+
+ Remove some arbitrary limits on goto numbers and relations.
+ * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit

+ (set_goto_map): ngotos is now unsigned, so test for overflow
+ by seeing whether it wraps around to zero.
+ * src/lalr.h (goto_number): Now size_t, not short int.
+ (GOTO_NUMBER_MAXIMUM): Remove.
+ * src/relation.c (relation_print, traverse, relation_transpose):

+
+2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Language and Grammar): In example, "int" is a

+
+2004-10-11 Akim Demaille <akim@epita.fr>
+
+ * src/symtab.c (symbol_check_alias_consistency): Also check

+
+ * src/parse-gram.y (add_param): Fix the truncation of trailing

+
+2004-10-05 Akim Demaille <akim@epita.fr>
+
+ In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
+ whether the reducion was empty or not. This leaves room to
+ improve the use of YYLLOC_DEFAULT in such a case.
+ lalr1.cc is still experimental, so changing this is acceptable.
+ And finally, there are probably not many users who changed the
+ handling of locations in GLR, so changing is admissible too.
+
+ * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
+ empty reduction, set @$ to an empty location ending the previously
+ stacked symbol.
+ Adjust uses to make sure the code is triggered on empty
+ reductions.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
+ expected output: empty reductions have empty locations.
+
+2004-09-29 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc: Move towards a more standard C++ coding style
+ for templates: Class < T > -> Class<T>.
+
+2004-09-29 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc: Reinstall the former ctor, for sake of

+ Move towards a more standard C++ coding style (i.e., type *var ->
+ type* var).
+
+2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/parse-gram.y (add_param): Rewrite to avoid strchr,
+ since it's less likely to work if NULs are involved in the future.
+
+2004-09-27 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.

+
+ * src/parse-gram.y (add_param): Strip the leading and trailing

+
+ * doc/bison.texinfo (Table of Symbols): Sort.
+
+2004-09-21 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove

+ Suggested by Paul Eggert.
+
+2004-09-20 Akim Demaille <akim@epita.fr>
+
+ Let the initial-action act on the look-ahead, and use it for the
+ "initial push" (corresponding to an hypothetical beginning-of-file).
+ And let lalr1.cc honor %initial-action.
+
+ * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
+ example.
+ * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
+ (Parser::Parser): Remove the ctor that used to initialize it.
+ (Parser::parse): Like in the other skeletons, issue the "starting
+ parse" message before any action.
+ Honor %initial-action.
+ Initialize the stacks with the lookahead.
+ * data/yacc.c: Let $$ and @$ in %initial-action designate the
+ look-ahead.
+ Push them in the stacks.
+ * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
+
+2004-09-20 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (Initial Action Decl): New.
+
+2004-09-20 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
+ clearer criterion to define it.
+ (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
+ When reducing on an empty RHS, use the latest stacked location as
+ location.
+ yylloc is not always available.
+ * data/glr.c: Likewise.
+ Also, honor initial-actions.
+
+2004-09-20 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c (YY_LOCATION_PRINT): New.
+ Define when we know YYLTYPE's structure, i.e., when the default
+ YYLLOC_DEFAULT is used.
+ * data/c.m4 (b4_yysymprint_generate): Use it.
+ * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
+ value of the result.
+ (error_start_): Replace with...
+ (error_range_): this location array.
+ This allows to replace code relying on the implementation of
+ locations by portable code.
+ * data/yacc.c (yylerrsp): Replace with...
+ (yyerror_range): this.
+ Every time a token is popped, update yyerror_range[0], to have an
+ accurate location for the error token.
+ * data/glr.c (YY_LOCATION_PRINT): New.
+ (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
+ deference a pointer.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
+ report the location in %printers.
+
+ * src/scan-skel.l: Instead of abort, report error messages to ease

+
+2004-09-16 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
+ (iterator, const_iterator): these, to be more in the C++ spirit.
+ Also, return reverse iterators so that when displaying the stack
+ we display its bottom first.
+ (Parser::stack_print_, Parser::reduce_print_): Match the messages
+ from yacc.c.
+ We should probably use vector here though.
+
+2004-09-16 Akim Demaille <akim@epita.fr>
+
+ Have more complete shift traces.
+
+ * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
+ to report Shifts instead of ad hoc YYDPRINTF invocations,
+ including for the error token.
+ * data/lalr1.cc (symprint_): Output the location.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
+ output the location within the %printer.
+ Activate GLR tests, at least to make sure they compile properly.
+ They still don't pass though.
+ * tests/calc.at: Adjust expect verbose output, since now "Entering
+ state..." is on a different line than the "Shifting" message.
+
+2004-09-08 Akim Demaille <akim@epita.fr>
+
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
+ Bison directive from the Bison file to the invocation of this
+ macro, so that these directives are passed to
+ AT_BISON_OPTION_PUSHDEFS to get correct help macros.
+ Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
+ Move the AT_SETUP/AT_CLEANUP outside, to report as test title
+ the extra Bison directives instead of the whole series.
+ Change the grammar so that there are recoverable errors, and
+ unrecoverable errors. Now we can have the parser give up before
+ consuming the whole input. As a result we now can observe that
+ the lookahead is freed when needed.
+ Change the parser source to parse argv[1] instead of a hard coded
+ string.
+ Simplify yylex, and give a value and location to EOF.
+ Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
+ passed directives already coded in the file.
+ Add some tests to check the location of "error".
+ For some tests, the C++ parser is correct, and not yacc.c.
+ For other tests, they provide different, but unsatisfying, values,
+ so keep the C++ value so that at least one parser is "correct"
+ according to the test suite.
+ (Actions after errors): Remove, this is subsumed by the
+ AT_CHECK_PRINTER_AND_DESTRUCTOR series.

+
+2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ Adjust to latest gnulib.

+
+2004-06-21 Paul Eggert <eggert@cs.ucla.edu>

+ C++ compiler. (trivial change)
+
+2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ Spent a few hours checking out which prerequisite versions the
+ current sources actually require. I went all the way back to
+ Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
+ a seemingly endless set of combinations of versions more recent
+ than that. The bottom line is that the current sources require
+ fairly recent versions of the build tools, and it'll be some work
+ to change this.
+ * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
+ (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
+ (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
+ Add comments explaining why those particular versions are
+ currently needed.
+
+ * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
+ in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
+ <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
+
+ * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
+ (it fails with a Autoconf-without-aclocal-m4 diagnostic).
+
+2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
+ 0.11.5. Suggested by Bruno Haible.
+ * bootstrap: Remove gettext version checking.
+
+ * doc/bison.texinfo (Decl Summary): Also mention that %union
+ can depend on prerequisite types. Problem reported by Tim
+ Van Holder.
+
+2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * README: Mention GNU m4 1.4 bugs and Akim's patched version.
+ * README-alpha: Don't tell people not to package this.
+
+ * bootstrap: Don't assume $(...) works; use `...` instead.
+ Problem reported by Paul Hilfinger. Also, diagnose non-GNU
+ gettext better.
+
+ * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
+ put into the -d output file, and mention what to do if YYSTYPE is
+ defined as a macro.
+
+2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ Undo change made earlier today: it caused autopoint to not bring
+ in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
+ autopoint's.
+
+ * bootstrap: Check that gettext version matches what's in
+ configure.ac. Warn users to ignore robots.txt ERROR 404.
+ * bootstrap: Undo today's earlier change (logged below).
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
+
+ The gettext version checking is causing more trouble than it's
+ curing; remove it. Problem reported by Paul Hilfinger.
+
+ * bootstrap: Issue a warning that one can expect a message
+ 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
+
+2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ Ensure that the C++ compiler used for testing actually works on a

+
+ * configure.ac (AC_INIT): Update to 1.875e.

+
+ * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
+ -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
+ lalr1.cc runs afoul of the first, and the last two are no longer
+ supported by GCC 3.4.0.
+ * README: Mention GNU m4 1.4 or later; mention m4 patches.
+ * HACKING: Use ./bootstrap, not "make update" to import foreign files.
+
+2004-05-06 Paul Eggert <eggert@cs.ucla.edu>

+
+2004-04-28 Paul Eggert <eggert@twinsun.com>
+
+ Get files from the gnulib and po repositories, instead of relying
+ on them being in our CVS. Upgrade to latest versions of gnulib
+ and Automake.
+
+ * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
+ * bootstrap: Bootstrap from gnulib and po repositories.
+ Much of this code was stolen from GNU diff and GNU tar's bootstrap.
+ * README-cvs: Document these changes. Remove version numbers from
+ mentions of build tools, since they change so often. Mention Flex.
+
+ * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
+ (gl_USE_SYSTEM_EXTENSIONS): Add.
+ (AC_GNU_SOURCE, AC_AIX, AC_MINIX):

+ does this for us.

+ ancient OS, as it gets in the way of latest Autoconf & gnulib.
+ (AC_HEADER_STDC): Remove: we now assume C89 or better.
+ (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
+ Do not check for C89 headers, except for locale.h which is used
+ by the Yacc library and must port to K&R hosts.
+ (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.

+ for us.
+
+ * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
+ (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
+ Define to empty, as gnulib.mk will do the rest for us.
+ ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
+ for us.
+ (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
+ (lib_SOURCES): New symbol, containing only the non-gnulib libs.

+ that invoked YYFILL in separate subexpressions, and YYFILL assigned
+ to a local variable. The C standard says that expressions
+ like (var = f ()) + (var = f ()) have undefined behavior.
+ Another problem was that GCC sometimes issues warnings that
+ yyfill and its parameters are unused.
+
+ * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
+ as possibly unused.
+ (yyfill): New function.
+ (YYFILL): Use it.
+ (yyuserAction): Change type of yynormal to bool, so that it matches
+ the new yyfill signature. Mark it as possibly unused.
+
+
+ Follow up on a bug I reported in February, where a Bison-generated
+ parser can loop. Provide a test case and a fix for yacc.c. I
+ don't have a fix for lalr1.cc or for glr.c, unfortunately.
+ The original bug report is in:
+ <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
+
+ * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
+ macro's size was becoming unwieldy.
+ (yyerrlab): Do not discard an empty lookahead symbol, as this
+ might destroy garbage.
+ (yyerrorlab): New label, with the old contents of YYERROR,
+ plus the following change: pop the stack of rhs corresponding
+ to the production that invoked YYERROR. That is how Yacc
+ behaves, and POSIX requires this behavior.
+ (yyerrlab1): Use YYPOPSTACK instead of its definiens.
+ * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
+ Define 'alarm' to do nothing if unistd.h is not available.
+ Add a new rule "exp: '-' error;" to test the above change to
+ data/yacc.c. Use 'alarm' to abort any test taking longer than
+ 10 seconds, as it's probably looping.
+ (AT_CHECK_CALC): Test recovery from error in new grammar rule.
+ Also, the new yacc.c generates two fewer diagnostics for an
+ existing test.
+
+2003-05-24 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
+ YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
+ This fixes a problem reported by John Bowman when the Compaq/HP
+ Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
+ -ansi -Wall -gall).
+ * data/yacc.c (union yyalloc): Likewise.

+
+ * config/install-sh: Sync from automake 1.7.5.
+
+2003-05-14 Paul Eggert <eggert@twinsun.com>
+
+ * src/parse-gram.y (rules_or_grammar_declaration): Require a
+ semicolon after a grammar declaration, in the interest of possible
+ future changes to the Bison input language.
+ Do not allow a stray semicolon at the start of the grammar.
+ (rhses.1): Allow one or more semicolons after any rule, including

+
+2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
+
+ %parse-param support for lalr1.cc.
+
+ * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
+ b4_cc_constructor_calls, b4_cc_constructor_call,
+ b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4

+ (yy::b4_parser_class_name::b4_parser_class_name): Take extra
+ parse-param arguments.
+ (yy::b4_parser_class_name): Declare instance variables to
+ hold parse-param arguments.
+ * tests/calc.at: s/value/semantic_value/ because value clashes
+ with a member of yy::b4_parser_class_name. Adjust C++ code
+ to handle %parse-param. Enable %parse-param test in C++.
+
+2003-05-12 Paul Eggert <eggert@twinsun.com>
+
+ * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
+ English a bit. Fix fclose typo. Change "const char" to "char
+ const", and use ANSI C rather than K&R for "main". Suggest
+ YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
+ and suggest yy_switch_to_buffer.
+
+2003-05-05 Paul Eggert <eggert@twinsun.com>
+
+ * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
+ C89. This avoids a diagnostic on compilers that define __STDC__
+ to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
+
+2003-05-03 Paul Eggert <eggert@twinsun.com>
+
+ * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
+ Do not overrun array bounds.
+ This should fix a bug reported today by Olatunji Oluwabukunmi in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
+
+2003-04-29 Akim Demaille <akim@epita.fr>
+
+ * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
+ * src/getargs.c, src/getargs.h: here, as bool, not int.
+ (nondeterministic_parser): New.
+ * src/parse-gram.y, src/scan-gram.l: Support
+ %nondeterministic-parser.
+ * src/output.c (prepare): Use nondeterministic_parser instead
+ of glr_parser where appropriate.
+ * src/tables.c (conflict_row, action_row, save_row)
+ (token_actions, token_actions, pack_vector): Ditto.
+
+2003-04-29 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
+
+2003-04-29 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
+ with %pure-parser and %locations to exercise the patch from Yakov
+ Markovitch below.
+
+2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
+
+ * data/yacc.c: (b4_lex_param): Corrected for the case where
+ %lex-param is provided and %pure-parser isn't.
+
+2003-04-27 Paul Eggert <eggert@twinsun.com>
+
+ Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
+ * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
+ if it is not defined.
+ (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
+
+2003-04-26 Paul Eggert <eggert@twinsun.com>
+
+ * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
+ Declare to be of type suitable for the ninf value itself, not of
+ type suitable for the corresponding table, since the latter might
+ be unsigned but the ninf value might be negative. This fixes a
+ bug reported by Alexandre Duret-Lutz in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
+
+ * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
+ invokes it. We shouldn't invoke it twice because it will attempt
+ to put error.o in the archive twice. This fixes a glitch reported
+ by Martin Mokrejs in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
+
+2003-04-21 Paul Eggert <eggert@twinsun.com>
+

+ to gnulib.
+
+2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
+
+ * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
+ Fix obvious typo that results in uncompilable GLR parsers
+ when both %pure-parser and %locations are used. (trivial change)
+
+2003-04-17 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l: Add %option nounput, since we no longer use unput.
+ (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
+ Do not insert the expected token via unput, as this runs afoul
+ of a POSIX-compatibility bug in flex 2.5.31.
+ All uses changed to BEGIN the parent state,
+ since we no longer insert the expected token via unput.
+ * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
+ that is no longer emitted after the above change.
+
+ * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
+ the first one. This change is from Paul Hilfinger, and it fixes
+ regression reported by Werner Lemberg in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
+
+ (resolve_sr_conflict): Don't invoke state_errs_set
+ unless one or more tokens have been explicitly made errors.
+ Otherwise, the above change causes Bison to abort.
+
+ * tests/existing.at (GNU pic Grammar): New test case, taken from
+ Lemberg's email.
+
+2003-03-31 Akim Demaille <akim@epita.fr>

+2003-03-12 Paul Eggert <eggert@twinsun.com>
+
+ * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
+ (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
+ cursor, instead of leaving it undefined. This fixes a bug
+ reported by Tim Van Holder in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
+ * tests/input.at (Torturing the Scanner): Test the scanner on
+ an empty input file, which was Tim Van Holder's test case.
+
+ * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
+ <sys/resource.h> can be included, include sys/time.h and
+ sys/times.h first, if available. This works around the SunOS
+ 4.1.4 porting bug reported by Bruce Becker in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
+
+ * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
+ AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
+ AC_HEADER_SYS_WAIT.
+
+ Merge changes from gnulib. This was prompted because the CVS
+ snapshot didn't build on Solaris 7 due to strnlen problems.
+
+ These changes need to be merged back into gnulib:
+ * lib/hash.c: Include <stdbool.h> unconditionally.
+ * m4/onceonly.m4 (m4_quote): New macro.
+ (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):

+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to

+ cannot be a non terminal.
+
+2003-03-02 Akim Demaille <akim@epita.fr>

+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ Create tests/local.at for Bison generic testing macros.
+
+ * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...

+ * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
+ (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...

+ Ignore the test if CXX is not functional.
+
+2003-03-01 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
+ not loc->end, since loc->end might contain garbage and this leads
+ to undefined behavior on some platforms.
+ (id_loc, token_start): Use (IF_LINTed) initial values that do not
+ depend on *loc, so that the reader doesn't give the the false
+ impression that *loc is initialized.
+ (<INITIAL>"%%"): Do not bother setting code_start, since its value
+ does not survive the return.
+
+2003-03-01 Akim Demaille <akim@epita.fr>
+
+ * src/scan-gram.l (code_start): Always initialize it when entering
+ into yylex, as SC_EPILOGUE is activated *before* the corresponding
+ yylex invocation. An alternative would be making it static, but
+ then it starts with the second %%'s beginning, instead of its end.
+
+2003-02-28 Paul Eggert <eggert@twinsun.com>
+
+ * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work

+ Suggested by Paul Eggert.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (position.hh): Make sure "columns" never pushes

+ Use "last" so that we subtract from Positions, not from unsigned.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (position.hh): New subfile, including the extended

+ With the help of Benoit Perrot.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
+ AT_YACC_IF.
+ Redefine AT_YYERROR_SEES_LOC_IF using it.
+ (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
+ not defined.
+ Don't use the location in yy::Parser::error_ and

+ Activate more lalr1.cc tests.

+ Disable the lalr1.cc tests as currently it doesn't support YYERROR.
+
+2003-02-17 Paul Eggert <eggert@twinsun.com>

+
+ * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
+
+2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
+
+ * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
+ of $1.
+
+ Changes in response to error report by S. Eken: GLR mode does not
+ handle negative $ indices or $ indices in embedded rules correctly.
+ See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
+
+ * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
+ (b4_rhs_location): Ditto.
+ (yyfill): New function to copy from stack tree into array
+ incrementally.
+ (yyuserAction): Modify to allow incremental move of semantic values
+ to rhs array when in GLR mode.
+ Define YYFILL to use in user-defined actions to fill semantic array
+ as needed.
+ Remove dummy use of yystack, as there is now a guaranteed use.
+ (yydoAction): Modify to allow incremental move of semantic values

+2003-01-28 Paul Eggert <eggert@twinsun.com>
+
+ * data/lalr1.cc: Do not use @output_header_name@ unless

+
+2003-01-21 Paul Eggert <eggert@twinsun.com>
+
+ * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
+ we don't need to worry about yyerrlab1 being reported as an
+ "unused label" by non-GCC C compilers. The downside is that if
+ locations are used then a couple of statements are duplicated each
+ time YYERROR is invoked, but the upside is that the warnings
+ should vanish.
+ (yyerrlab1): Move code to YERROR.
+ (yyerrlab2): Remove. Change uses back to yyerrlab1.
+ This reverts some of the 2002-12-27 change.
+
+2003-01-17 Paul Eggert <eggert@twinsun.com>
+
+ * src/output.c (symbol_printers_output): Fix typo that led

+ Quoc Peyrot <chojin@lrde.epita.fr>,
+ Robert Anisko <anisko_r@lrde.epita.fr>
+
+ * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
+ when the stacks contain one element, as the loop would otherwise
+ free the last state, and then use the top state (the one we just
+ popped). This means that the initial elements will not be freed
+ explicitly, as is the case in yacc.c; it is not a problem, as
+ these elements have fake values.
+
+2003-01-11 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS: %expect-violations are now just warnings, reverting

+
+2003-01-06 Paul Eggert <eggert@twinsun.com>

+ * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
+ (EXTRA_SCRIPTS): New var, for yacc.
+
+ * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
+ since GNU C++ (as of 3.2.1) does not allow attributes on labels.
+ Problem reported by Nelson H. F. Beebe.
+
+2003-01-03 Paul Eggert <eggert@twinsun.com>
+
+ * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
+ (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
+ when compiling Bison 1.875's `bitset bset = obstack_alloc
+ (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
+
+ * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
+ ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
+ grow to a huge size with typical invocation.
+
+ * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
+ Use the pattern recommended by Autoconf 2.57, except also protect

+ * src/system.h: Likewise.
+ Portability issues reported by Nelson H. F. Beebe.
+
+ * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
+ All uses changed. Provide a definition in both C and C++.
+ (yytrue, yyfalse): Define even if defined (__cplusplus).
+
+ * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
+ Reported by Nelson H. F. Beebe.

+
+2003-01-02 Paul Eggert <eggert@twinsun.com>

+
+2002-12-30 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
+ Moved here from...
+ (<INITIAL>","): Here. This causes stray "," to be treated
+ more uniformly.
+
+ * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
+ last brace in braced code when not in Yacc mode, for compatibility
+ with Bison 1.35. This resurrects the 2001-12-15 patch to
+ src/reader.c.
+
+ * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
+ yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
+
+2002-12-28 Paul Eggert <eggert@twinsun.com>
+
+ * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be

+
+2002-12-28 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.75f.
+
+ Switch back to the Yacc style of conflict reports, undoing some
+ of the 2002-07-30 change.
+ * doc/bison.texinfo (Understanding): Use Yacc style for
+ conflict reports. Also, use new way of locating rules.
+ * src/conflicts.c (conflict_report):
+ Renamed from conflict_report_yacc, removing the old
+ 'conflict_report'. Translate the entire conflict report at once,
+ so that we don't assume that "," has the same interpretation in
+ all languages.
+ (conflicts_output): Use Yacc-style conflict report for each state,
+ instead of our more-complicated style.
+ (conflicts_print): Use Yacc-style conflict report, except print
+ the input file name when not emulating Yacc.
+ * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
+ Conflicted Reduction, %expect not enough, %expect too much,
+ %expect with reduce conflicts): Switch to Yacc-style conflict reports.
+ * tests/existing.at (GNU Cim Grammar): Likewise.
+ * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
+
+ * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
+ fatal): Don't invoke fflush; it's not needed and it might even be
+ harmful for stdout, as stdout might not be open.
+ * src/reduce.c (reduce_print): Likewise.
+
+2002-12-27 Paul Eggert <eggert@twinsun.com>
+
+ Fix a bug where error locations were not being recorded correctly.
+ This problem was originally reported by Paul Hilfinger in
+ <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
+
+ * data/yacc.c (yyparse): New local var yylerrsp, to record the
+ top of the location stack's error locations.
+ (yyerrlab): Set it. When discarding a token, push its location
+ onto yylerrsp so that we don't lose track of the error's end.
+ (yyerrlab1): Now is only the target of YYERROR, so that we can
+ properly record the location of the action that failed. For GCC
+ 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
+ GCC warning about yyerrlab1 being unused if YYERROR is unused.
+ (yyerrlab2): New label, which yyerrlab now falls through to.
+ Compute the error's location by applying YYLLOC_DEFAULT to
+ the locations of all the symbols that went into the error.
+ * doc/bison.texinfo (Location Default Action): Mention that
+ YYLLOC_DEFAULT is also invoked for syntax errors.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
+ Error locations include the locations of all the tokens that were
+ discarded, not just the last token.
+
+2002-12-26 Paul Eggert <eggert@twinsun.com>
+
+ * src/files.c: Include quote.h.
+ (compute_output_file_names): Warn if we detect conflicting
+ outputs to the same file. This should catch the misunderstanding
+ exemplified by Debian Bug 165349, reported by Bruce Stephens..
+
+ * src/conflicts.c (conflicts_print): If the user specifies
+ "%expect N", report an error if there are any reduce/reduce
+ conflicts. This is what the manual says should happen.
+ This fixes Debian bug 130890, reported by Anthony DeRobertis.
+ * tests/conflicts.at (%expect with reduce conflicts): New test.
+
+ Don't use m4_include on relative file names, as it doesn't work as
+ desired if there happens to be a file with that name under ".".
+
+ * m4sugar/version.m4: Remove; it was included but it wasn't used.
+ * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
+ * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
+ * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
+ * src/output.c (output_skeleton): Use full path names when
+ specifying a file to include; don't rely on include path, as
+ it's unreliable when the working file contains a file with
+ that name.
+
+2002-12-25 Paul Eggert <eggert@twinsun.com>
+
+ Remove obsolete references to bison.simple and bison.hairy.
+ Problem mentioned by Aubin Mahe in
+ <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
+ * data/glr.c: Comment fix.
+ * doc/bison.1: Remove references. Also, mention "yacc".
+
+ * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
+ with -g option.
+
+ * src/parse-gram.y (declaration): Use enum "report_states" rather
+ than its numeric value 1.
+
+ * src/scan-skel.l ("@output ".*\n): Close any old yyout before
+ opening a new one. This fixes Debian bug 165349, reported by
+ Bruce Stephens.
+
+2002-12-24 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.75e.
+
+ * Makefile.maint (cvs-update): Don't assume that the shell
+ supports $(...), as Solaris sh doesn't.
+
+ * src/parse-gram.y (lloc_default): Remove test for empty
+ nonterminals at the end, since it didn't change the result.
+
+2002-12-24 Paul Eggert <eggert@twinsun.com>
+
+ If the user does not define YYSTYPE as a macro, Bison now declares it
+ using typedef instead of defining it as a macro. POSIX requires this.
+ For consistency, YYLTYPE is also declared instead of defined.
+
+ %union directives can now have a tag before the `{', e.g., the
+ directive `%union foo {...}' now generates the C code
+ `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
+ The default union tag is `YYSTYPE', for compatibility with Solaris 9
+ Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
+ instead of `yyltype'.
+
+ `yystype' and `yyltype' are now obsolescent macros instead of being
+ typedefs or tags; they are no longer documented and will be
+ withdrawn in a future release.
+
+ * data/glr.c (b4_location_type): Remove.
+ (YYSTYPE): Renamed from yystype.
+ (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
+ (struct YYLTYPE): Renamed from struct yyltype.
+ (YYLTYPE): Renamed from yyltype.
+ (yyltype, yystype): New (and obsolescent) macros,
+ for backward compatibility.
+ * data/yacc.c: Likewise.
+
+ * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
+ does not specify a union tag. This is for compatibility with
+ Solaris 9 yacc.
+
+ * src/parse-gram.y (add_param): 2nd arg is now char * not char
+ const *, since it is now modified by stripping surrounding { }.
+ (current_braced_code): Remove.
+ (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
+ PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
+ trailing " {...}". Now of type <chars>.
+ (grammar_declaration): Adjust to bundled tokens.
+ (code_content): Remove; stripping is now done by add_param.
+ (print_token_value): Print contents of bundled tokens.
+ (token_name): New function.
+
+ * src/reader.h (braced_code, current_braced_code): Remove.
+ (token_name): New decl.
+
+ * src/scan-gram.l (handle_dollar, handle_at): Now takes int
+ token_type, not braced_code code_kind. All uses changed.
+ (SC_PRE_CODE): New state, for scanning after a keyword that
+ has (or usually has) an immediately-following braced code.
+ (token_type): New local var, to keep track of which token type
+ to return when scanning braced code.
+ (<INITIAL>"%destructor", <INITIAL>"%lex-param",
+ <INITIAL>"%parse-param", <INITIAL>"%printer",
+ <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
+ instead of returning a token type immediately.
+ (<INITIAL>"{"): Set token type.
+ (<SC_BRACED_CODE>"}"): Use it.
+ (handle_action_dollar, handle_action_at): Now returns bool
+ indicating success. Fail if ! current_rule; this prevents a core dump.
+ (handle_symbol_code_dollar, handle_symbol_code_at):
+ Remove; merge body into caller.
+ (handle_dollar, handle_at): Complain in invalid contexts.
+
+ * NEWS, doc/bison.texinfo: Document the above.
+ * NEWS: Fix years and program names in copyright notice.
+
+2002-12-17 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error

+
+2002-12-15 Paul Eggert <eggert@twinsun.com>
+
+ Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
+ GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
+ lookahead symbol, and which sets yychar in parser actions) and it
+ disagreed with the Bison documentation. Bug
+ reported by Andrew Walrond.
+
+ * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
+ as the caller now does that.
+ (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
+ (YYEMPTY): Parenthesize right hand side, since others use it.
+ (yyparse): Don't assume that our generated code is the only code
+ that sets yychar.
+
+2002-12-13 Paul Eggert <eggert@twinsun.com>

+
+2002-12-12 Paul Eggert <eggert@twinsun.com>
+
+ Remove unportable casts and storage allocation tricks.
+ While we're at it, remove almost all casts, since they

+
+ * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
+
+ * src/derives.c (derives_compute): Do not subtract NTOKENS from

+ * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
+
+ * src/derives.c (derives_compute): Do not bother invoking

+ Put "const" consistently after the type it modifies. Mention
+ that C99 supports "inline". Mention that yyerror traditionally

+ (COMMA): Remove.

+
+ * data/yacc.c (yyerrlab1): Move this label down, so that the

+
+ * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
+ "$CC -E foo.h" is allowed, as this doesn't work with the Portland
+ Group compiler. Instead, use "$CC -E bar.c". Include the .h
+ file twice in the grammar, as an extra check.
+
+ * tests/input.at (Torturing the Scanner): Surround the
+ backslash-newline tests with "#if 0", to make it less likely that

+ <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
+
+ * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
+ -o c"; the HP C compiler chatters during compilation.
+ Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
+ * tests/headers.at (export YYLTYPE): Likewise.
+
+ * tests/input.at (Torturing the Scanner): Remove lines containing
+ solitary backslashes, as they tickle a bug in the HP C compiler.
+
+ * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
+ comments, since they're not portable. Use GNU coding style.
+
+2002-11-13 Akim Demaille <akim@epita.fr>
+

+ Use it.
+
+2002-11-12 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.75b.
+
+ * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
+ (yyglrReduce): Return yyok, not 0.
+ This should avoid the enumerated-type warnings reported

+
+ * lib/bbitset.h (BITSET_INLINE): Remove.

+ This fixes one of the bugs reported by Nelson H. F. Beebe in
+ <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
+
+ * Makefile.maint (po-check): Scan .l and .y files instead of the
+ .c and the .h files that they generate. This fixes the bug
+ reported by Tim Van Holder in:
+ <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
+ Look for N_ as well as for _. Try to avoid matching #define for

+
+ * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.

+2002-11-11 Paul Eggert <eggert@twinsun.com>
+
+ Revamp to fix many (but not all) of the C- and M4-related quoting

+ by Jan Hubicka when processing the Bash grammar; see:
+ <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
+
+ Use new @ escapes consistently. Represent brackets with @{ and @}
+ rather than @<:@ and @:>@, since this works a bit better with dumb
+ editors like vi. Represent @ with @@, since @ is now consistently
+ an escape. Use @oline@ and @ofile@ rather than __oline__ and
+ __ofile__, to avoid unexpected expansions. Similarly, use @output
+ rather than #output.
+
+ * data/c.m4 (b4_copyright): Omit file name from comment, since
+ the file name could contain "*/".
+ (b4_synclines_flag): Don't quote the 2nd argument; it should already
+ be quoted. All uses changed.
+
+ * data/glr.c: Use new @ escapes consistently.
+ (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,

+
+ * src/files.c (output_infix): Remove; all uses removed.
+ * src/files.h: Likewise.

+ needed any more.
+ * data/yacc.c: Likewise.
+ * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
+
+ * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
+ * data/yacc.c: Likewise.
+

+ (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.

+ * src/reader.c (prologue_augment, epilogue_set): Likewise.
+
+ * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash

+ (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
+ SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
+ Use new escapes @{ and @} for [ and ].
+
+ * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
+ them with auto vars.
+ Switch to new escape scheme, where @ is the escape character uniformly.
+ Abort if a stray escape character is found. Avoid unbounded input
+ buffer when parsing non-escaped text.
+
+ * tests/input.at (Torturing the Scanner): Add tests that @oline@,

+
+2002-11-09 Paul Eggert <eggert@twinsun.com>
+
+ Fix the test failure due to GCC warnings described in

+ table.
+ (yygetLRActions, yyrecoverParseError): Use them.
+
+ * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
+ counted in the token inserted at end of file. Now takes

+
+ * tests/regression.at (Invalid inputs): Adjust wording in

+
+ * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
+ AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
+ AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))

+ GCC 3.2.
+
+2002-11-07 Paul Eggert <eggert@twinsun.com>
+
+ * src/parse-gram.y (CHARACTER): Remove unused token.
+ All uses removed.
+
+ * src/scan-gram.l: Remove stack option. We no longer use the
+ stack, since the stack was never deeper than 1; instead, use the
+ new auto var c_context to record the stacked value.
+
+ Remove nounput option. At an unexpected end of file, we now unput
+ the minimal input necessary to end cleanly; this simplifies the
+ code.
+
+ Avoid unbounded token sizes where this is easy.
+
+ (unexpected_end_of_file): New function.
+ Use it to systematize the error message on unexpected EOF.
+ (last-string): Now auto, not static.
+ (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
+ (scanner_last_string_free): Remove; not used.

+ SunOS 3.5, and that's too old to worry about now.
+
+ * data/glr.c (struct yyltype): Define members even when not

+ http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
+ http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html

+
+ * data/README: New.
+
+2002-10-21 Paul Eggert <eggert@twinsun.com>

+ * src/getargs.c (usage): Likewise.
+
+ * src/getargs.c (getargs): When there are too few operands, report

+
+ Let nondeterministic skeletons be usable with deterministic
+ tables.
+
+ With the patch, GAWK compiled by GCC without -O2 passes its test
+ suite using a GLR parser driven by LALR tables. It fails with -O2
+ because `struct stat' gives two different answers on my machine:
+ 88 (definition of an auto var) and later 96 (memset on this var).
+ Hence the stack is badly corrumpted. The headers inclusion is to
+ blame: if I move the awk.h inclusion before GLR's system header
+ inclusion, the two struct stat have the same size.

+ * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
+ shamelessly stolen from CVS Autoconf.
+
+2002-02-05 Akim Demaille <akim@epita.fr>
+
+ * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.

+ * src/muscle_tab.c: Adjust.
+
+2002-02-05 Akim Demaille <akim@epita.fr>
+
+ * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
+ which have no values.
+
+2002-02-05 Akim Demaille <akim@epita.fr>
+
+ * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
+ * data/: here.
+
+2002-01-29 Paul Eggert <eggert@twinsun.com>
+
+ * src/bison.simple (YYSIZE_T): Do not define merely because
+ YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
+ On some platforms, <alloca.h> does not declare YYSTD (size_t).
+
+2002-01-27 Akim Demaille <akim@epita.fr>
+
+ Fix `%nonassoc and eof'.
+
+ * src/state.c (errs_dup): Aaaah! The failure was due to bytes
+ which were not properly copied! Replace
+ memcpy (res->errs, src->errs, src->nerrs);
+ with
+ memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
+ !!!
+ * tests/regression.at (%nonassoc and eof): Adjust to newest
+ Autotest: `.' is not in the PATH.
+
+2002-01-27 Akim Demaille <akim@epita.fr>
+
+ * tests/sets.at (AT_EXTRACT_SETS): New.
+ (Nullable): Use it.
+ (Firsts): New.
+
+2002-01-26 Akim Demaille <akim@epita.fr>
+
+ * tests/actions.at, tests/calc.at, tests/headers.at,
+ * tests/torture.at: Adjust to the newest Autotest which no longer
+ forces `.' in the PATH.
+
+2002-01-25 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (%nonassoc and eof): New.
+ Suggested by Robert Anisko.
+
+2002-01-24 Akim Demaille <akim@epita.fr>
+
+ Bison dumps core when trying to complain about broken input files.

+2002-01-21 Paolo Bonzini <bonzini@gnu.org>
+
+ * po/it.po: New.
+
+2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
+
+ * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
+
+2002-01-20 Marc Autret <marc@gnu.org>
+
+ * src/files.c (compute_output_file_names): Fix
+
+2002-01-20 Marc Autret <marc@gnu.org>
+
+ * tests/output.at: New test.
+ * src/files.c (compute_base_names): Don't map extensions when

+ Reported by Evgeny Stambulchik.
+
+2002-01-20 Marc Autret <marc@gnu.org>
+
+ * src/system.h: Need to define __attribute__ away for non-GCC
+ compilers as well (i.e., the vendor C compiler).
+ Suggested by Albert Chin-A-Young.
+
+2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
+
+ * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
+ canonical definition.
+ * src/system.h: Use the canonical definition for PARAMS (avoids
+ a conflict with the macro from lib/hash.h).
+
+2002-01-11 Akim Demaille <akim@epita.fr>
+
+ * configure.in: Use AC_FUNC_STRNLEN.
+ Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
+
+2002-01-09 Akim Demaille <akim@epita.fr>
+
+ * src/files.c, src/files.h (output_infix): New.
+ (tab_extension): Remove.
+ (compute_base_names): Compute the former, drop the latter.
+ * src/output.c (prepare): Insert the muscles `output-infix', and

+ * src/bison.simple, src/bison.hairy: Adjust.
+
+2002-01-09 Akim Demaille <akim@epita.fr>
+
+ * configure.in (WERROR_CFLAGS): Compute it.
+ * src/Makefile.am (CFLAGS): Pass it.

+ * src/files.c: Fix a few warnings.
+ (get_extension_index): Remove, unused.
+
+2002-01-08 Akim Demaille <akim@epita.fr>
+
+ * src/getargs.c (AS_FILE_NAME): New.
+ (getargs): Use it to convert DOSish file names.
+ * src/files.c (base_name): Rename as full_base_name to avoid
+ clashes with `base_name ()'.
+ (filename_split): New.
+ (compute_base_names): N-th rewrite, using filename_split.
+
+2002-01-08 Akim Demaille <akim@epita.fr>
+
+ * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
+ New, stolen from the Fileutils 4.1.
+ * lib/Makefile.am (libbison_a_SOURCES): Adjust.
+ * configure.in: Check for the presence of memrchr, and of its
+ prototype.
+
+2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
+
+ * lib/hash.h (__P): Added definition for this macro.
+ * src/Makefile.am: Add parse-skel.c and scan-skel.c to
+ BUILT_SOURCES, to ensure they are generated first.
+ * src/parse-skel.y: Use YYERROR_VERBOSE instead of
+ %error-verbose to allow bootstrapping with bison 1.30x.
+
+2002-01-06 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (parse_braces): Don't fetch the next char, the
+ convention is to fetch on entry.
+ * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
+ 'switch' without a following semicolon.
+ * tests/regression.at (braces parsing): New.
+
+2002-01-06 Akim Demaille <akim@epita.fr>
+
+ Bison is dead wrong in its RR conflict reports.
+
+ * tests/torture.at (GNU Cim Grammar): New.
+ * src/conflicts.c (count_rr_conflicts): Fix.
+
+2002-01-06 Akim Demaille <akim@epita.fr>
+
+ Creating package.m4 from configure.ac causes too many problems.
+
+ * tests/Makefile.am (package.m4): Create it by hand,
+ AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
+
+2002-01-06 Akim Demaille <akim@epita.fr>
+
+ * src/Makefile.am (bison_SOURCES): Add parse-skel.h and

+
+2002-01-04 Paul Eggert <eggert@twinsun.com>

+
+2002-01-03 Akim Demaille <akim@epita.fr>

+
+2002-01-03 Akim Demaille <akim@epita.fr>
+
+ * src/parse-skel.y (process_skeleton): Don't bind the parser's

+ args.
+
+2002-01-03 Akim Demaille <akim@epita.fr>
+
+ * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
+ The ISO C++ standard is extremely clear about it: stderr is
+ considered a macro, not a regular symbol (see table 94 `Header
+ <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
+ Therefore std:: does not apply to it. It still does with fprintf.
+ Also, s/cstdio.h/cstdio/.
+
+2002-01-03 Akim Demaille <akim@epita.fr>
+
+ * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'

+
+2002-01-02 Akim Demaille <akim@epita.fr>
+
+ Equip the skeleton chain with location tracking, runtime trace,
+ pure parser and scanner.
+
+ * src/parse-skel.y: Request a pure parser, locations, and prefix
+ renaming.
+ (%union): Having several members with the same type does not help
+ type mismatches, simplify.
+ (YYPRINT, yyprint): New.
+ (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
+ (skel_error): this.
+ Handle locations.
+ * src/scan-skel.l: Adjust to these changes.
+ * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
+ (LOCATION_PRINT, skel_control_t): New.
+
+2001-12-30 Akim Demaille <akim@epita.fr>
+
+ * src/parse-skel.y: Get rid of the shift/reduce conflict:
+ replace `gb' with BLANKS.
+ * src/scan-skel.l: Adjust.
+
+2001-12-30 Akim Demaille <akim@epita.fr>
+
+ * src/system.h: We don't need nor want bcopy.
+ Throw away MS-DOS crap: we don't need getpid.
+ * configure.in: We don't need strndup. It was even causing
+ problems: because Flex includes the headers *before* us,
+ _GNU_SOURCE is not defined by config.h, and therefore strndup was
+ not visible.
+ * lib/xstrndup.c: New.
+ * src/scan-skel.l: Use it.
+ Be sure to initialize yylval.muscle member when scanning a MUSCLE.
+ * src/parse-skel.y: Use %directives instead of #defines.
+
+2001-12-30 Akim Demaille <akim@epita.fr>
+
+ * src/skeleton.h: New.
+ * src/output.c (output_parser, output_master_parser): Remove, dead
+ code.
+ * src/output.h (get_lines_number, actions_output, guards_output)
+ (token_definitions_output): Prototype them.
+ * src/parse-skel.y: Add the license notice.
+ Include output.h and skeleton.h.
+ (process_skeleton): Returns void, and takes a single parameter.
+ * src/scan-skel.l: Add the license notice.
+ Include skeleton.h.
+ Don't use %option yylineno: it seems that then Flex imagines
+ REJECT has been used, and therefore it won't reallocate its
+ buffers (which makes no other sense to me than a bug). It results
+ in warnings for `unused: yy_flex_realloc'.
+
+2001-12-30 Robert Anisko <robert.anisko@epita.fr>
+
+ * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)

+ * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
+ (MUSCLE_INSERT_PREFIX): Move from here...
+
+ * src/bison.hairy: Add a section directive. Put braces around muscle
+ names. This parser skeleton is still broken, but Bison should not
+ choke on a bad muscle 'syntax'.
+ * src/bison.simple: Add a section directive. Put braces around muscle
+ names.
+
+ * src/files.h (strsuffix, stringappend): Add declarations.
+ (tab_extension): Add declaration.

+ (token_definitions_output, get_lines_number): No longer static.
+
+ * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.

+ * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
+ parse-skel.y.
+
+ * src/parse-skel.y: New file.
+ * src/scan-skel.l: New file.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ %name-prefix is broken.
+
+ * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
+ Adjust all dependencies.
+ * tests/headers.at (export YYLTYPE): Strengthen this test: use
+ %name-prefix.
+
+ Renaming yylval but not yylloc is not consistent. Now we do.
+
+ * src/bison.simple: Prefix yylloc if used.
+ * doc/bison.texinfo (Decl Summary): Document that.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo: Promote `%long-directive' over

+ Remove all references to fixed-output-files, yacc is enough.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the

+ define YYDEBUG and YYERROR_VERBOSE.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (header_output): Don't forget to export YYLTYPE and

+
+2001-12-29 Akim Demaille <akim@epita.fr>

+ * src/reader.c (symbols_save): Remove.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+

+2001-12-29 Akim Demaille <akim@epita.fr>

+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (Web2c Actions): Blindly move the actual

+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (readgram): Don't add the rule 0 if there were no

+
+2001-12-29 Akim Demaille <akim@epita.fr>
+

+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (readgram): Bind the initial rule's lineno to that

+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ Fix the `GAWK Grammar' failure.
+
+ * src/LR0.c (final_state): Initialize to -1 so that we do compute

+ with the final state because precisely final_state was initialized
+ to 0.
+ * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,

+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',

+
+ * src/output.c: Comment changes.
+
+2001-12-27 Paul Eggert <eggert@twinsun.com>
+
+ * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
+ cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
+ Sparc, as they were causing more porting problems than the
+ (minor) performance improvement was worth.
+
+ Also, catch up with 1.31's YYSTD.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (output_gram): Rely on nritems, not the
+ 0-sentinel. See below.
+ Use -1 as separator, not 0.
+ * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
+ Rely on -1 as separator in yyrhs, instead of 0.
+ * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
+ twice `Now at end of input', therefore there are two lines less to
+ expect.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (Unresolved SR Conflicts):
+ (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
+ below.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+

+ is reached by eoftoken.
+ (insert_start_shifting_state, insert_eof_shifting_state)
+ (insert_accepting_state, augment_automaton): Remove, since now
+ these states are automatically computed from the initial state.
+ (generate_states): Adjust.
+ * src/print.c: When reporting a rule number to the user, subtract
+ 1, so that the axiom rule is rule 0, and the first user rule is 1.
+ * src/reduce.c: Likewise.
+ * src/print_graph.c (print_core): For the time being, just as for
+ the report, depend upon --trace-flags to dump the full set of
+ items.
+ * src/reader.c (readgram): Once the grammar read, insert the rule
+ 0: `$axiom: START-SYMBOL $'.
+ * tests/set.at: Adjust: rule 0 is now displayed, and since the
+ number of the states has changed (the final state is no longer
+ necessarily the last), catch up.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ Try to make the use of the eoftoken valid. Given that its value
+ is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
+ is used instead of > 0 where appropriate, (ii), depend upon nritems
+ instead of the 0-sentinel.
+
+ * src/gram.h, src/gram.c (nritems): New.

+ (packsymbols): No longer hack `tags' to insert `$' by hand.
+ Be sure to preserve the value of the eoftoken.
+ (reader): Make sure eoftoken is defined.
+ Initialize nsyms to 0: now eoftoken is created just like the others.
+ * src/print.c (print_grammar): Don't special case the eof token.
+ * src/regression.at: Adjust: `$' has value 0, not -1, which was a
+ lie anyway, albeit pleasant.

+ Change the grammar so that empty input is invalid.
+ Adjust expectations.
+ When yyungeting, be sure to use a valid yylloc: use last_yylloc.

+
+ * src/nullable.c (set_nullable): Useless rules must be skipped,

+
+ * tests/torture.at (GNU AWK Grammar): New.

+
+ Work around Autotest bugs.
+
+ * src/warshall.c (bitmatrix_print): Don't use `+--+' as table

+ * tests/regression.at: Adjust some tests.
+ * src/print_graph.c (print_core): Complete the set of items via
+ closure. The next-to-final and final states are still unsatisfying,

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+

+ state number.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ Now that states have a complete set of members, the linked list of

+
+ * src/state.h (shifts): Remove the `next' member.
+ * src/LR0.c (first_state, last_state): Remove.
+ Adjust the callers.
+ (augment_automaton): Don't look for the shifts that must be added
+ a shift on EOF: it is those of the state we looked for! But now,

+ merely by its id: its number.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (augment_automaton): Better variable locality.
+ Remove an impossible branch: if there is a state corresponding to

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+

+ * tests/regression.at (Rule Line Numbers): Adjust.
+
+2001-12-10 Akim Demaille <akim@epita.fr>

+ Better locality of the variables.
+ When looking if the start_symbol is shifted from the initial

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/getargs.h: Don't declare `spec_name_prefix' and

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ Now that states have a complete set of members, the linked list of

+2001-12-05 Akim Demaille <akim@epita.fr>
+
+ New experimental feature: if --verbose --trace output all the

+
+2001-12-05 Akim Demaille <akim@epita.fr>
+
+ * src/lalr.c (transpose): Free the memory allocated to the

+
+2001-12-05 Akim Demaille <akim@epita.fr>
+
+ Because useless nonterminals are now kept alive (instead of being

+
+ * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
+ static.
+ * src/LR0.c (allocate_itemsets): The memory allocated to

+ given state.
+ Deobfuscate, i.e., allocate, use and free `symbol_count' here
+ only, and...
+ (new_itemsets): Allocate `shift_symbol' here.
+ (allocate_itemsets): symbol_count includes useless nonterminals.
+ Make room for them.

+ be null.
+
+2001-12-05 Akim Demaille <akim@epita.fr>

+
+ * src/gram.c, src/gram.h (ritem_print): New.

+ ritem.
+
+2001-12-04 Paul Eggert <eggert@twinsun.com>
+
+ * src/bison.simple (union yyalloc): Change member names
+ to be the same as the stack names.
+ (yyparse): yyptr is now union yyalloc *, not char *.
+ (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
+ and may generate better code on some machines.

+
+2001-11-30 Akim Demaille <akim@epita.fr>

+ (SIZE_MAX, UINT_MAX): New macros.
+ (quotearg_n_options): Abort if N is negative.
+ Avoid overflow check on hosts where size_t is 64 bits and int

+ Fix off-by-one typo that caused unnecessary reallocation.
+
+2001-11-29 Paul Eggert <eggert@twinsun.com>
+
+ Name space cleanup in generated parser.
+
+ * doc/bison.texinfo (Bison Parser): Discuss system headers

+
+ (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
+ All uses changed.
+
+ (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
+ instead of relying on string.h functions. Use YYSTACK_ALLOC
+ and YYSTACK_FREE instead of malloc and free.
+
+2001-11-30 Akim Demaille <akim@epita.fr>

+ (union yyalloc): New type.
+ (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
+ an arbitrary restriction on hosts where size_t is wider than int.
+
+ (yyparse): Don't dump core if alloca or malloc fails; instead, report
+ a parser stack overflow. Allocate just one block of memory for all
+ three stacks, instead of allocating three blocks; this typically is
+ faster and reduces fragmentation.
+
+ Do not limit the number of items in the stack to a value that fits

+
+ The location tracking mechanism is precious for parse error
+ messages. Nevertheless, it is enabled only when `@n' is used in
+ the grammar, which is a different issue (you can use it in error
+ message, but not in the grammar per se). Therefore, there should
+ be another means to enable it.
+
+ * src/getargs.c (getargs): Support `--locations'.
+ (usage): Report it.
+ * src/getargs.h (locationsflag): Export it.
+ * src/lex.c (percent_table): Support `%locations'.

+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ Also test parse error messages, including with YYERROR_VERBOSE.

+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ Test also `--verbose', `--defines' and `--name-prefix'. Testing
+ the latter demonstrates a flaw in the handling of non debugging
+ parsers introduced by myself on 2000-03-16: `#define yydebug 0'
+ was used in order to simplify:
+
+ #if YYDEBUG
+ if (yydebug)
+ {
+ ...
+ }
+ #endif
+
+ into
+
+ if (yydebug)
+ {
+ ...
+ }
+
+ unfortunately this leads to a CPP conflict when
+ `--name-prefix=foo' is used since it produces `#define yydebug
+ foodebug'.
+
+ * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
+ (YYDPRINTF): New macro.
+ Spread its use.
+ * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
+ the bison options.
+ Also test `--verbose', `--defines' and `--name-prefix'.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ Improve the readability of the produced parsers.
+
+ * src/bison.s1: Formatting changes.

+ * src/output.c (output_parser): When the `$' is met, skip the end
+ of its line.
+ New variable, `number_of_dollar_signs', to check there's exactly
+ one `$' in the parser skeleton.

+
+ Use the more standard files `xalloc.h' and `xmalloc.c' instead of
+ Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
+ difficult and introduced a lot of core dump. It turns out that
+ Bison used an implementation of `xmalloc' based on `calloc', and
+ at various places it does depend upon the initialization to 0. I
+ have not tried to isolate the pertinent places, and all the former
+ calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
+ someone should address this issue.

+ major changes to files.c.
+ (lex) Retain in the incoming stream a character following
+ an incorrect '/'.
+ (skip_white_space, lex): Revised most error messages
+ and changed fatal to warn to avoid aborting.
+ (percent_table): Added %thong declarations.
+
+ * src/gram.h: Comment changes.
+
+ * src/files.c (openfiles, open_extra_files, done):
+ Add faction flag

+
+Basic Installation
+==================
+
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package. Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below. The lack of an optional feature in a given package is not
+necessarily a bug. More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package, generally using the just-built uninstalled binaries.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation. When installing into a prefix owned by root, it is
+ recommended that the package be configured and built as a regular
+ user, and only the `make install' phase executed with root
+ privileges.
+
+ 5. Optionally, type `make installcheck' to repeat any self-tests, but
+ this time using the binaries in their final installed location.
+ This target does not install anything. Running this target as a
+ regular user, particularly if the prior `make install' required
+ root privileges, verifies that the installation completed
+ correctly.
+
+ 6. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 7. Often, you can also type `make uninstall' to remove the installed
+ files again. In practice, not all packages have tested that
+ uninstallation works correctly, even though it is required by the
+ GNU Coding Standards.
+
+ 8. Some packages, particularly those that use Automake, provide `make
+ distcheck', which can by used by developers to test that all other
+ targets like `make install' and `make uninstall' work correctly.
+ This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'. This
+is known as a "VPATH" build.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them. In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+ The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+ The first method involves providing an override variable for each
+affected directory. For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'. Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated. The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+ The second method involves providing the `DESTDIR' variable. For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names. The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters. On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+ Some packages offer the ability to configure how verbose the
+execution of `make' will be. For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved. Use GNU `make'
+instead.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+ On Solaris, don't put `/usr/ucb' early in your `PATH'. This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+ On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'. It is recommended to use the following options:
+
+ ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS
+ KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf limitation. Until the limitation is lifted, you can use
+this workaround:
+
+ CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+# working copy (for example, when you run autoreconf && make). Allowing these
+# to fall out of sync appears to have little potential to improve Bison build
+# efficiency (even if we were to replace VERSION/PACKAGE_VERSION with .version
+# everywhere possible). On the other hand, it could be harmful. For example,
+# a developer might naively reference .version in a test case while the bison
+# executable still compiles with VERSION, and so the test case might fail or

+GNU Bison NEWS
+
+* Noteworthy changes in release 2.6 (2012-07-19) [stable]
+
+** Future Changes
+
+ The next major release of Bison will drop support for the following
+ deprecated features. Please report disagreements to bug-bison@gnu.org.
+
+*** K&C parsers
+
+ Support for generating parsers in K&R C will be removed. Parsers
+ generated for C support ISO C90, and are tested with ISO C99 and ISO C11
+ compilers.
+
+*** Features deprecated since Bison 1.875
+
+ The definitions of yystype and yyltype will be removed; use YYSTYPE and
+ YYLTYPE.
+
+ YYPARSE_PARAM and YYLEX_PARAM, deprecated in favor of %parse-param and
+ %lex-param, will no longer be supported.
+
+ Support for the preprocessor symbol YYERROR_VERBOSE will be removed, use
+ %error-verbose.
+
+*** The generated header will be included (yacc.c)
+
+ Instead of duplicating the content of the generated header (definition of
+ YYSTYPE, yyparse declaration etc.), the generated parser will include it,
+ as is already the case for GLR or C++ parsers. This change is deferred
+ because existing versions of ylwrap (e.g., Automake 1.12.1) do not support
+ it.
+
+** Generated Parser Headers
+
+*** Guards (yacc.c, glr.c, glr.cc)
+
+ The generated headers are now guarded, as is already the case for C++
+ parsers (lalr1.cc). For instance, with --defines=foo.h:
+
+ #ifndef YY_FOO_H
+ # define YY_FOO_H
+ ...
+ #endif /* !YY_FOO_H */
+
+*** New declarations (yacc.c, glr.c)
+
+ The generated header now declares yydebug and yyparse. Both honor
+ --name-prefix=bar_, and yield
+
+ int bar_parse (void);
+
+ rather than
+
+ #define yyparse bar_parse
+ int yyparse (void);
+
+ in order to facilitate the inclusion of several parser headers inside a
+ single compilation unit.
+
+*** Exported symbols in C++
+
+ The symbols YYTOKEN_TABLE and YYERROR_VERBOSE, which were defined in the
+ header, are removed, as they prevent the possibility of including several
+ generated headers from a single compilation unit.
+
+*** YYLSP_NEEDED
+
+ For the same reasons, the undocumented and unused macro YYLSP_NEEDED is no
+ longer defined.
+
+** New %define variable: api.prefix
+
+ Now that the generated headers are more complete and properly protected
+ against multiple inclusions, constant names, such as YYSTYPE are a
+ problem. While yyparse and others are properly renamed by %name-prefix,
+ YYSTYPE, YYDEBUG and others have never been affected by it. Because it
+ would introduce backward compatibility issues in projects not expecting
+ YYSTYPE to be renamed, instead of changing the behavior of %name-prefix,
+ it is deprecated in favor of a new %define variable: api.prefix.
+
+ The following examples compares both:
+
+ %name-prefix "bar_" | %define api.prefix "bar_"
+ %token <ival> FOO %token <ival> FOO
+ %union { int ival; } %union { int ival; }
+ %% %%
+ exp: 'a'; exp: 'a';
+
+ bison generates:
+
+ #ifndef BAR_FOO_H #ifndef BAR_FOO_H
+ # define BAR_FOO_H # define BAR_FOO_H
+
+ /* Enabling traces. */ /* Enabling traces. */
+ # ifndef YYDEBUG | # ifndef BAR_DEBUG

+
+* Noteworthy changes in release 2.5.1 (2012-06-05) [stable]
+
+** Future changes:
+
+ The next major release will drop support for generating parsers in K&R C.
+
+** yacc.c: YYBACKUP works as expected.
+
+** glr.c improvements:
+
+*** Location support is eliminated when not requested:
+
+ GLR parsers used to include location-related code even when locations were
+ not requested, and therefore not even usable.
+
+*** __attribute__ is preserved:
+
+ __attribute__ is no longer disabled when __STRICT_ANSI__ is defined (i.e.,
+ when -std is passed to GCC).
+
+** lalr1.java: several fixes:
+
+ The Java parser no longer throws ArrayIndexOutOfBoundsException if the
+ first token leads to a syntax error. Some minor clean ups.
+
+** Changes for C++:
+
+*** C++11 compatibility:
+
+ C and C++ parsers use "nullptr" instead of "0" when __cplusplus is 201103L
+ or higher.
+
+*** Header guards
+
+ The header files such as "parser.hh", "location.hh", etc. used a constant
+ name for preprocessor guards, for instance:
+
+ #ifndef BISON_LOCATION_HH
+ # define BISON_LOCATION_HH
+ ...
+ #endif // !BISON_LOCATION_HH
+
+ The inclusion guard is now computed from "PREFIX/FILE-NAME", where lower
+ case characters are converted to upper case, and series of
+ non-alphanumerical characters are converted to an underscore.
+
+ With "bison -o lang++/parser.cc", "location.hh" would now include:
+
+ #ifndef YY_LANG_LOCATION_HH
+ # define YY_LANG_LOCATION_HH
+ ...
+ #endif // !YY_LANG_LOCATION_HH
+
+*** C++ locations:
+
+ The position and location constructors (and their initialize methods)
+ accept new arguments for line and column. Several issues in the
+ documentation were fixed.
+
+** liby is no longer asking for "rpl_fprintf" on some platforms.
+
+** Changes in the manual:
+
+*** %printer is documented
+
+ The "%printer" directive, supported since at least Bison 1.50, is finally
+ documented. The "mfcalc" example is extended to demonstrate it.
+
+ For consistency with the C skeletons, the C++ parsers now also support
+ "yyoutput" (as an alias to "debug_stream ()").
+
+*** Several improvements have been made:
+
+ The layout for grammar excerpts was changed to a more compact scheme.
+ Named references are motivated. The description of the automaton
+ description file (*.output) is updated to the current format. Incorrect
+ index entries were fixed. Some other errors were fixed.
+
+** Building bison:
+
+*** Conflicting prototypes with recent/modified Flex.
+
+ Fixed build problems with the current, unreleased, version of Flex, and
+ some modified versions of 2.5.35, which have modified function prototypes.
+
+*** Warnings during the build procedure have been eliminated.
+
+*** Several portability problems in the test suite have been fixed:
+
+ This includes warnings with some compilers, unexpected behavior of tools
+ such as diff, warning messages from the test suite itself, etc.
+
+*** The install-pdf target works properly:
+
+ Running "make install-pdf" (or -dvi, -html, -info, and -ps) no longer
+ halts in the middle of its course.
+
+* Changes in version 2.5 (2011-05-14):
+
+** Grammar symbol names can now contain non-initial dashes:
+
+ Consistently with directives (such as %error-verbose) and with
+ %define variables (e.g. push-pull), grammar symbol names may contain
+ dashes in any position except the beginning. This is a GNU
+ extension over POSIX Yacc. Thus, use of this extension is reported
+ by -Wyacc and rejected in Yacc mode (--yacc).
+
+** Named references:
+
+ Historically, Yacc and Bison have supported positional references
+ ($n, $$) to allow access to symbol values from inside of semantic
+ actions code.
+
+ Starting from this version, Bison can also accept named references.
+ When no ambiguity is possible, original symbol names may be used
+ as named references:
+
+ if_stmt : "if" cond_expr "then" then_stmt ';'
+ { $if_stmt = mk_if_stmt($cond_expr, $then_stmt); }
+
+ In the more common case, explicit names may be declared:
+
+ stmt[res] : "if" expr[cond] "then" stmt[then] "else" stmt[else] ';'
+ { $res = mk_if_stmt($cond, $then, $else); }
+
+ Location information is also accessible using @name syntax. When
+ accessing symbol names containing dots or dashes, explicit bracketing
+ ($[sym.1]) must be used.
+
+ These features are experimental in this version. More user feedback
+ will help to stabilize them.
+
+** IELR(1) and canonical LR(1):
+
+ IELR(1) is a minimal LR(1) parser table generation algorithm. That
+ is, given any context-free grammar, IELR(1) generates parser tables
+ with the full language-recognition power of canonical LR(1) but with
+ nearly the same number of parser states as LALR(1). This reduction
+ in parser states is often an order of magnitude. More importantly,
+ because canonical LR(1)'s extra parser states may contain duplicate
+ conflicts in the case of non-LR(1) grammars, the number of conflicts
+ for IELR(1) is often an order of magnitude less as well. This can
+ significantly reduce the complexity of developing of a grammar.
+
+ Bison can now generate IELR(1) and canonical LR(1) parser tables in
+ place of its traditional LALR(1) parser tables, which remain the
+ default. You can specify the type of parser tables in the grammar
+ file with these directives:
+
+ %define lr.type lalr
+ %define lr.type ielr
+ %define lr.type canonical-lr
+
+ The default-reduction optimization in the parser tables can also be
+ adjusted using "%define lr.default-reductions". For details on both
+ of these features, see the new section "Tuning LR" in the Bison
+ manual.
+
+ These features are experimental. More user feedback will help to
+ stabilize them.
+
+** LAC (Lookahead Correction) for syntax error handling:
+
+ Canonical LR, IELR, and LALR can suffer from a couple of problems
+ upon encountering a syntax error. First, the parser might perform
+ additional parser stack reductions before discovering the syntax
+ error. Such reductions can perform user semantic actions that are
+ unexpected because they are based on an invalid token, and they
+ cause error recovery to begin in a different syntactic context than
+ the one in which the invalid token was encountered. Second, when
+ verbose error messages are enabled (with %error-verbose or the
+ obsolete "#define YYERROR_VERBOSE"), the expected token list in the
+ syntax error message can both contain invalid tokens and omit valid
+ tokens.
+
+ The culprits for the above problems are %nonassoc, default
+ reductions in inconsistent states, and parser state merging. Thus,
+ IELR and LALR suffer the most. Canonical LR can suffer only if
+ %nonassoc is used or if default reductions are enabled for
+ inconsistent states.
+
+ LAC is a new mechanism within the parsing algorithm that solves
+ these problems for canonical LR, IELR, and LALR without sacrificing
+ %nonassoc, default reductions, or state merging. When LAC is in
+ use, canonical LR and IELR behave almost exactly the same for both
+ syntactically acceptable and syntactically unacceptable input.
+ While LALR still does not support the full language-recognition
+ power of canonical LR and IELR, LAC at least enables LALR's syntax
+ error handling to correctly reflect LALR's language-recognition
+ power.
+
+ Currently, LAC is only supported for deterministic parsers in C.
+ You can enable LAC with the following directive:
+
+ %define parse.lac full
+
+ See the new section "LAC" in the Bison manual for additional
+ details including a few caveats.
+
+ LAC is an experimental feature. More user feedback will help to
+ stabilize it.
+
+** %define improvements:
+
+*** Can now be invoked via the command line:
+
+ Each of these command-line options
+
+ -D NAME[=VALUE]
+ --define=NAME[=VALUE]
+
+ -F NAME[=VALUE]
+ --force-define=NAME[=VALUE]
+
+ is equivalent to this grammar file declaration
+
+ %define NAME ["VALUE"]
+
+ except that the manner in which Bison processes multiple definitions
+ for the same NAME differs. Most importantly, -F and --force-define
+ quietly override %define, but -D and --define do not. For further
+ details, see the section "Bison Options" in the Bison manual.
+
+*** Variables renamed:
+
+ The following %define variables
+
+ api.push_pull
+ lr.keep_unreachable_states
+
+ have been renamed to
+
+ api.push-pull
+ lr.keep-unreachable-states
+
+ The old names are now deprecated but will be maintained indefinitely
+ for backward compatibility.
+
+*** Values no longer need to be quoted in the grammar file:
+
+ If a %define value is an identifier, it no longer needs to be placed
+ within quotations marks. For example,
+
+ %define api.push-pull "push"
+
+ can be rewritten as
+
+ %define api.push-pull push
+
+*** Unrecognized variables are now errors not warnings.
+
+*** Multiple invocations for any variable is now an error not a warning.
+
+** Unrecognized %code qualifiers are now errors not warnings.
+
+** Character literals not of length one:
+
+ Previously, Bison quietly converted all character literals to length
+ one. For example, without warning, Bison interpreted the operators in
+ the following grammar to be the same token:
+
+ exp: exp '++'
+ | exp '+' exp
+ ;
+
+ Bison now warns when a character literal is not of length one. In
+ some future release, Bison will start reporting an error instead.
+
+** Destructor calls fixed for lookaheads altered in semantic actions:
+
+ Previously for deterministic parsers in C, if a user semantic action
+ altered yychar, the parser in some cases used the old yychar value to
+ determine which destructor to call for the lookahead upon a syntax
+ error or upon parser return. This bug has been fixed.
+
+** C++ parsers use YYRHSLOC:
+
+ Similarly to the C parsers, the C++ parsers now define the YYRHSLOC
+ macro and use it in the default YYLLOC_DEFAULT. You are encouraged
+ to use it. If, for instance, your location structure has "first"
+ and "last" members, instead of
+
+ # define YYLLOC_DEFAULT(Current, Rhs, N) \
+ do \
+ if (N) \
+ { \
+ (Current).first = (Rhs)[1].location.first; \
+ (Current).last = (Rhs)[N].location.last; \
+ } \
+ else \
+ { \
+ (Current).first = (Current).last = (Rhs)[0].location.last; \
+ } \
+ while (false)
+
+ use:
+
+ # define YYLLOC_DEFAULT(Current, Rhs, N) \
+ do \
+ if (N) \
+ { \
+ (Current).first = YYRHSLOC (Rhs, 1).first; \
+ (Current).last = YYRHSLOC (Rhs, N).last; \
+ } \
+ else \
+ { \
+ (Current).first = (Current).last = YYRHSLOC (Rhs, 0).last; \
+ } \
+ while (false)
+
+** YYLLOC_DEFAULT in C++:
+
+ The default implementation of YYLLOC_DEFAULT used to be issued in
+ the header file. It is now output in the implementation file, after
+ the user %code sections so that its #ifndef guard does not try to
+ override the user's YYLLOC_DEFAULT if provided.
+
+** YYFAIL now produces warnings and Java parsers no longer implement it:
+
+ YYFAIL has existed for many years as an undocumented feature of
+ deterministic parsers in C generated by Bison. More recently, it was
+ a documented feature of Bison's experimental Java parsers. As
+ promised in Bison 2.4.2's NEWS entry, any appearance of YYFAIL in a
+ semantic action now produces a deprecation warning, and Java parsers
+ no longer implement YYFAIL at all. For further details, including a
+ discussion of how to suppress C preprocessor warnings about YYFAIL
+ being unused, see the Bison 2.4.2 NEWS entry.
+
+** Temporary hack for adding a semicolon to the user action:
+
+ Previously, Bison appended a semicolon to every user action for
+ reductions when the output language defaulted to C (specifically, when
+ neither %yacc, %language, %skeleton, or equivalent command-line
+ options were specified). This allowed actions such as
+
+ exp: exp "+" exp { $$ = $1 + $3 };
+
+ instead of
+
+ exp: exp "+" exp { $$ = $1 + $3; };
+
+ As a first step in removing this misfeature, Bison now issues a
+ warning when it appends a semicolon. Moreover, in cases where Bison
+ cannot easily determine whether a semicolon is needed (for example, an
+ action ending with a cpp directive or a braced compound initializer),
+ it no longer appends one. Thus, the C compiler might now complain
+ about a missing semicolon where it did not before. Future releases of
+ Bison will cease to append semicolons entirely.
+
+** Verbose syntax error message fixes:
+
+ When %error-verbose or the obsolete "#define YYERROR_VERBOSE" is
+ specified, syntax error messages produced by the generated parser
+ include the unexpected token as well as a list of expected tokens.
+ The effect of %nonassoc on these verbose messages has been corrected
+ in two ways, but a more complete fix requires LAC, described above:
+
+*** When %nonassoc is used, there can exist parser states that accept no
+ tokens, and so the parser does not always require a lookahead token
+ in order to detect a syntax error. Because no unexpected token or
+ expected tokens can then be reported, the verbose syntax error
+ message described above is suppressed, and the parser instead
+ reports the simpler message, "syntax error". Previously, this
+ suppression was sometimes erroneously triggered by %nonassoc when a
+ lookahead was actually required. Now verbose messages are
+ suppressed only when all previous lookaheads have already been
+ shifted or discarded.
+
+*** Previously, the list of expected tokens erroneously included tokens
+ that would actually induce a syntax error because conflicts for them
+ were resolved with %nonassoc in the current parser state. Such
+ tokens are now properly omitted from the list.
+
+*** Expected token lists are still often wrong due to state merging
+ (from LALR or IELR) and default reductions, which can both add
+ invalid tokens and subtract valid tokens. Canonical LR almost
+ completely fixes this problem by eliminating state merging and
+ default reductions. However, there is one minor problem left even
+ when using canonical LR and even after the fixes above. That is,
+ if the resolution of a conflict with %nonassoc appears in a later
+ parser state than the one at which some syntax error is
+ discovered, the conflicted token is still erroneously included in
+ the expected token list. Bison's new LAC implementation,
+ described above, eliminates this problem and the need for
+ canonical LR. However, LAC is still experimental and is disabled
+ by default.
+
+** Java skeleton fixes:
+
+*** A location handling bug has been fixed.
+
+*** The top element of each of the value stack and location stack is now
+ cleared when popped so that it can be garbage collected.
+
+*** Parser traces now print the top element of the stack.
+
+** -W/--warnings fixes:
+
+*** Bison now properly recognizes the "no-" versions of categories:
+
+ For example, given the following command line, Bison now enables all
+ warnings except warnings for incompatibilities with POSIX Yacc:
+
+ bison -Wall,no-yacc gram.y
+
+*** Bison now treats S/R and R/R conflicts like other warnings:
+
+ Previously, conflict reports were independent of Bison's normal
+ warning system. Now, Bison recognizes the warning categories
+ "conflicts-sr" and "conflicts-rr". This change has important
+ consequences for the -W and --warnings command-line options. For
+ example:
+
+ bison -Wno-conflicts-sr gram.y # S/R conflicts not reported
+ bison -Wno-conflicts-rr gram.y # R/R conflicts not reported
+ bison -Wnone gram.y # no conflicts are reported
+ bison -Werror gram.y # any conflict is an error
+
+ However, as before, if the %expect or %expect-rr directive is
+ specified, an unexpected number of conflicts is an error, and an
+ expected number of conflicts is not reported, so -W and --warning
+ then have no effect on the conflict report.
+
+*** The "none" category no longer disables a preceding "error":
+
+ For example, for the following command line, Bison now reports
+ errors instead of warnings for incompatibilities with POSIX Yacc:
+
+ bison -Werror,none,yacc gram.y
+
+*** The "none" category now disables all Bison warnings:
+
+ Previously, the "none" category disabled only Bison warnings for
+ which there existed a specific -W/--warning category. However,
+ given the following command line, Bison is now guaranteed to
+ suppress all warnings:
+
+ bison -Wnone gram.y
+
+** Precedence directives can now assign token number 0:
+
+ Since Bison 2.3b, which restored the ability of precedence
+ directives to assign token numbers, doing so for token number 0 has
+ produced an assertion failure. For example:
+
+ %left END 0
+
+ This bug has been fixed.
+
+* Changes in version 2.4.3 (2010-08-05):
+
+** Bison now obeys -Werror and --warnings=error for warnings about
+ grammar rules that are useless in the parser due to conflicts.
+
+** Problems with spawning M4 on at least FreeBSD 8 and FreeBSD 9 have
+ been fixed.
+
+** Failures in the test suite for GCC 4.5 have been fixed.
+
+** Failures in the test suite for some versions of Sun Studio C++ have
+ been fixed.
+
+** Contrary to Bison 2.4.2's NEWS entry, it has been decided that
+ warnings about undefined %prec identifiers will not be converted to
+ errors in Bison 2.5. They will remain warnings, which should be
+ sufficient for POSIX while avoiding backward compatibility issues.
+
+** Minor documentation fixes.
+
+* Changes in version 2.4.2 (2010-03-20):
+
+** Some portability problems that resulted in failures and livelocks
+ in the test suite on some versions of at least Solaris, AIX, HP-UX,
+ RHEL4, and Tru64 have been addressed. As a result, fatal Bison
+ errors should no longer cause M4 to report a broken pipe on the
+ affected platforms.
+
+** "%prec IDENTIFIER" requires IDENTIFIER to be defined separately.
+
+ POSIX specifies that an error be reported for any identifier that does
+ not appear on the LHS of a grammar rule and that is not defined by
+ %token, %left, %right, or %nonassoc. Bison 2.3b and later lost this
+ error report for the case when an identifier appears only after a
+ %prec directive. It is now restored. However, for backward
+ compatibility with recent Bison releases, it is only a warning for
+ now. In Bison 2.5 and later, it will return to being an error.
+ [Between the 2.4.2 and 2.4.3 releases, it was decided that this
+ warning will not be converted to an error in Bison 2.5.]
+
+** Detection of GNU M4 1.4.6 or newer during configure is improved.
+
+** Warnings from gcc's -Wundef option about undefined YYENABLE_NLS,
+ YYLTYPE_IS_TRIVIAL, and __STRICT_ANSI__ in C/C++ parsers are now
+ avoided.
+
+** %code is now a permanent feature.
+
+ A traditional Yacc prologue directive is written in the form:
+
+ %{CODE%}
+
+ To provide a more flexible alternative, Bison 2.3b introduced the
+ %code directive with the following forms for C/C++:
+
+ %code {CODE}
+ %code requires {CODE}
+ %code provides {CODE}
+ %code top {CODE}
+
+ These forms are now considered permanent features of Bison. See the
+ %code entries in the section "Bison Declaration Summary" in the Bison
+ manual for a summary of their functionality. See the section
+ "Prologue Alternatives" for a detailed discussion including the
+ advantages of %code over the traditional Yacc prologue directive.
+
+ Bison's Java feature as a whole including its current usage of %code
+ is still considered experimental.
+
+** YYFAIL is deprecated and will eventually be removed.
+
+ YYFAIL has existed for many years as an undocumented feature of
+ deterministic parsers in C generated by Bison. Previously, it was
+ documented for Bison's experimental Java parsers. YYFAIL is no longer
+ documented for Java parsers and is formally deprecated in both cases.
+ Users are strongly encouraged to migrate to YYERROR, which is
+ specified by POSIX.
+
+ Like YYERROR, you can invoke YYFAIL from a semantic action in order to
+ induce a syntax error. The most obvious difference from YYERROR is
+ that YYFAIL will automatically invoke yyerror to report the syntax
+ error so that you don't have to. However, there are several other
+ subtle differences between YYERROR and YYFAIL, and YYFAIL suffers from
+ inherent flaws when %error-verbose or "#define YYERROR_VERBOSE" is
+ used. For a more detailed discussion, see:
+
+ http://lists.gnu.org/archive/html/bison-patches/2009-12/msg00024.html
+
+ The upcoming Bison 2.5 will remove YYFAIL from Java parsers, but
+ deterministic parsers in C will continue to implement it. However,
+ because YYFAIL is already flawed, it seems futile to try to make new
+ Bison features compatible with it. Thus, during parser generation,
+ Bison 2.5 will produce a warning whenever it discovers YYFAIL in a
+ rule action. In a later release, YYFAIL will be disabled for
+ %error-verbose and "#define YYERROR_VERBOSE". Eventually, YYFAIL will
+ be removed altogether.
+
+ There exists at least one case where Bison 2.5's YYFAIL warning will
+ be a false positive. Some projects add phony uses of YYFAIL and other
+ Bison-defined macros for the sole purpose of suppressing C
+ preprocessor warnings (from GCC cpp's -Wunused-macros, for example).
+ To avoid Bison's future warning, such YYFAIL uses can be moved to the
+ epilogue (that is, after the second "%%") in the Bison input file. In
+ this release (2.4.2), Bison already generates its own code to suppress
+ C preprocessor warnings for YYFAIL, so projects can remove their own
+ phony uses of YYFAIL if compatibility with Bison releases prior to
+ 2.4.2 is not necessary.
+
+** Internationalization.
+
+ Fix a regression introduced in Bison 2.4: Under some circumstances,
+ message translations were not installed although supported by the
+ host system.
+
+* Changes in version 2.4.1 (2008-12-11):
+
+** In the GLR defines file, unexpanded M4 macros in the yylval and yylloc
+ declarations have been fixed.
+
+** Temporary hack for adding a semicolon to the user action.
+
+ Bison used to prepend a trailing semicolon at the end of the user
+ action for reductions. This allowed actions such as
+
+ exp: exp "+" exp { $$ = $1 + $3 };
+
+ instead of
+
+ exp: exp "+" exp { $$ = $1 + $3; };
+
+ Some grammars still depend on this "feature". Bison 2.4.1 restores
+ the previous behavior in the case of C output (specifically, when
+ neither %language or %skeleton or equivalent command-line options
+ are used) to leave more time for grammars depending on the old
+ behavior to be adjusted. Future releases of Bison will disable this
+ feature.
+
+** A few minor improvements to the Bison manual.
+
+* Changes in version 2.4 (2008-11-02):
+
+** %language is an experimental feature.
+
+ We first introduced this feature in test release 2.3b as a cleaner
+ alternative to %skeleton. Since then, we have discussed the possibility of
+ modifying its effect on Bison's output file names. Thus, in this release,
+ we consider %language to be an experimental feature that will likely evolve
+ in future releases.
+
+** Forward compatibility with GNU M4 has been improved.
+
+** Several bugs in the C++ skeleton and the experimental Java skeleton have been
+ fixed.
+
+* Changes in version 2.3b (2008-05-27):
+
+** The quotes around NAME that used to be required in the following directive
+ are now deprecated:
+
+ %define NAME "VALUE"
+
+** The directive "%pure-parser" is now deprecated in favor of:
+
+ %define api.pure
+
+ which has the same effect except that Bison is more careful to warn about
+ unreasonable usage in the latter case.
+
+** Push Parsing
+
+ Bison can now generate an LALR(1) parser in C with a push interface. That
+ is, instead of invoking "yyparse", which pulls tokens from "yylex", you can
+ push one token at a time to the parser using "yypush_parse", which will
+ return to the caller after processing each token. By default, the push
+ interface is disabled. Either of the following directives will enable it:
+
+ %define api.push_pull "push" // Just push; does not require yylex.
+ %define api.push_pull "both" // Push and pull; requires yylex.
+
+ See the new section "A Push Parser" in the Bison manual for details.
+
+ The current push parsing interface is experimental and may evolve. More user
+ feedback will help to stabilize it.
+
+** The -g and --graph options now output graphs in Graphviz DOT format,
+ not VCG format. Like --graph, -g now also takes an optional FILE argument
+ and thus cannot be bundled with other short options.
+
+** Java
+
+ Bison can now generate an LALR(1) parser in Java. The skeleton is
+ "data/lalr1.java". Consider using the new %language directive instead of
+ %skeleton to select it.
+
+ See the new section "Java Parsers" in the Bison manual for details.
+
+ The current Java interface is experimental and may evolve. More user
+ feedback will help to stabilize it.
+
+** %language
+
+ This new directive specifies the programming language of the generated
+ parser, which can be C (the default), C++, or Java. Besides the skeleton
+ that Bison uses, the directive affects the names of the generated files if
+ the grammar file's name ends in ".y".
+
+** XML Automaton Report
+
+ Bison can now generate an XML report of the LALR(1) automaton using the new
+ "--xml" option. The current XML schema is experimental and may evolve. More
+ user feedback will help to stabilize it.
+
+** The grammar file may now specify the name of the parser header file using
+ %defines. For example:
+
+ %defines "parser.h"
+
+** When reporting useless rules, useless nonterminals, and unused terminals,
+ Bison now employs the terms "useless in grammar" instead of "useless",
+ "useless in parser" instead of "never reduced", and "unused in grammar"
+ instead of "unused".
+
+** Unreachable State Removal
+
+ Previously, Bison sometimes generated parser tables containing unreachable
+ states. A state can become unreachable during conflict resolution if Bison
+ disables a shift action leading to it from a predecessor state. Bison now:
+
+ 1. Removes unreachable states.
+
+ 2. Does not report any conflicts that appeared in unreachable states.
+ WARNING: As a result, you may need to update %expect and %expect-rr
+ directives in existing grammar files.
+
+ 3. For any rule used only in such states, Bison now reports the rule as
+ "useless in parser due to conflicts".
+
+ This feature can be disabled with the following directive:
+
+ %define lr.keep_unreachable_states
+
+ See the %define entry in the "Bison Declaration Summary" in the Bison manual
+ for further discussion.
+
+** Lookahead Set Correction in the ".output" Report
+
+ When instructed to generate a ".output" file including lookahead sets
+ (using "--report=lookahead", for example), Bison now prints each reduction's
+ lookahead set only next to the associated state's one item that (1) is
+ associated with the same rule as the reduction and (2) has its dot at the end
+ of its RHS. Previously, Bison also erroneously printed the lookahead set
+ next to all of the state's other items associated with the same rule. This
+ bug affected only the ".output" file and not the generated parser source
+ code.
+
+** --report-file=FILE is a new option to override the default ".output" file
+ name.
+
+** The "=" that used to be required in the following directives is now
+ deprecated:
+
+ %file-prefix "parser"
+ %name-prefix "c_"
+ %output "parser.c"
+
+** An Alternative to "%{...%}" -- "%code QUALIFIER {CODE}"
+
+ Bison 2.3a provided a new set of directives as a more flexible alternative to
+ the traditional Yacc prologue blocks. Those have now been consolidated into
+ a single %code directive with an optional qualifier field, which identifies
+ the purpose of the code and thus the location(s) where Bison should generate
+ it:
+
+ 1. "%code {CODE}" replaces "%after-header {CODE}"
+ 2. "%code requires {CODE}" replaces "%start-header {CODE}"
+ 3. "%code provides {CODE}" replaces "%end-header {CODE}"
+ 4. "%code top {CODE}" replaces "%before-header {CODE}"
+
+ See the %code entries in section "Bison Declaration Summary" in the Bison
+ manual for a summary of the new functionality. See the new section "Prologue
+ Alternatives" for a detailed discussion including the advantages of %code
+ over the traditional Yacc prologues.
+
+ The prologue alternatives are experimental. More user feedback will help to
+ determine whether they should become permanent features.
+
+** Revised warning: unset or unused mid-rule values
+
+ Since Bison 2.2, Bison has warned about mid-rule values that are set but not
+ used within any of the actions of the parent rule. For example, Bison warns
+ about unused $2 in:
+
+ exp: '1' { $$ = 1; } '+' exp { $$ = $1 + $4; };
+
+ Now, Bison also warns about mid-rule values that are used but not set. For
+ example, Bison warns about unset $$ in the mid-rule action in:
+
+ exp: '1' { $1 = 1; } '+' exp { $$ = $2 + $4; };
+
+ However, Bison now disables both of these warnings by default since they
+ sometimes prove to be false alarms in existing grammars employing the Yacc
+ constructs $0 or $-N (where N is some positive integer).
+
+ To enable these warnings, specify the option "--warnings=midrule-values" or
+ "-W", which is a synonym for "--warnings=all".
+
+** Default %destructor or %printer with "<*>" or "<>"
+
+ Bison now recognizes two separate kinds of default %destructor's and
+ %printer's:
+
+ 1. Place "<*>" in a %destructor/%printer symbol list to define a default
+ %destructor/%printer for all grammar symbols for which you have formally
+ declared semantic type tags.
+
+ 2. Place "<>" in a %destructor/%printer symbol list to define a default
+ %destructor/%printer for all grammar symbols without declared semantic
+ type tags.
+
+ Bison no longer supports the "%symbol-default" notation from Bison 2.3a.
+ "<*>" and "<>" combined achieve the same effect with one exception: Bison no
+ longer applies any %destructor to a mid-rule value if that mid-rule value is
+ not actually ever referenced using either $$ or $n in a semantic action.
+
+ The default %destructor's and %printer's are experimental. More user
+ feedback will help to determine whether they should become permanent
+ features.
+
+ See the section "Freeing Discarded Symbols" in the Bison manual for further
+ details.
+
+** %left, %right, and %nonassoc can now declare token numbers. This is required
+ by POSIX. However, see the end of section "Operator Precedence" in the Bison
+ manual for a caveat concerning the treatment of literal strings.
+
+** The nonfunctional --no-parser, -n, and %no-parser options have been
+ completely removed from Bison.
+
+* Changes in version 2.3a, 2006-09-13:
+
+** Instead of %union, you can define and use your own union type
+ YYSTYPE if your grammar contains at least one <type> tag.
+ Your YYSTYPE need not be a macro; it can be a typedef.
+ This change is for compatibility with other Yacc implementations,
+ and is required by POSIX.
+
+** Locations columns and lines start at 1.
+ In accordance with the GNU Coding Standards and Emacs.
+
+** You may now declare per-type and default %destructor's and %printer's:
+
+ For example:
+
+ %union { char *string; }
+ %token <string> STRING1
+ %token <string> STRING2
+ %type <string> string1
+ %type <string> string2
+ %union { char character; }
+ %token <character> CHR
+ %type <character> chr
+ %destructor { free ($$); } %symbol-default
+ %destructor { free ($$); printf ("%d", @$.first_line); } STRING1 string1
+ %destructor { } <character>
+
+ guarantees that, when the parser discards any user-defined symbol that has a
+ semantic type tag other than "<character>", it passes its semantic value to
+ "free". However, when the parser discards a "STRING1" or a "string1", it
+ also prints its line number to "stdout". It performs only the second
+ "%destructor" in this case, so it invokes "free" only once.
+
+ [Although we failed to mention this here in the 2.3a release, the default
+ %destructor's and %printer's were experimental, and they were rewritten in
+ future versions.]
+
+** Except for LALR(1) parsers in C with POSIX Yacc emulation enabled (with "-y",
+ "--yacc", or "%yacc"), Bison no longer generates #define statements for
+ associating token numbers with token names. Removing the #define statements
+ helps to sanitize the global namespace during preprocessing, but POSIX Yacc
+ requires them. Bison still generates an enum for token names in all cases.
+
+** Handling of traditional Yacc prologue blocks is now more consistent but
+ potentially incompatible with previous releases of Bison.
+
+ As before, you declare prologue blocks in your grammar file with the
+ "%{ ... %}" syntax. To generate the pre-prologue, Bison concatenates all
+ prologue blocks that you've declared before the first %union. To generate
+ the post-prologue, Bison concatenates all prologue blocks that you've
+ declared after the first %union.
+
+ Previous releases of Bison inserted the pre-prologue into both the header
+ file and the code file in all cases except for LALR(1) parsers in C. In the
+ latter case, Bison inserted it only into the code file. For parsers in C++,
+ the point of insertion was before any token definitions (which associate
+ token numbers with names). For parsers in C, the point of insertion was
+ after the token definitions.
+
+ Now, Bison never inserts the pre-prologue into the header file. In the code
+ file, it always inserts it before the token definitions.
+
+** Bison now provides a more flexible alternative to the traditional Yacc
+ prologue blocks: %before-header, %start-header, %end-header, and
+ %after-header.
+
+ For example, the following declaration order in the grammar file reflects the
+ order in which Bison will output these code blocks. However, you are free to
+ declare these code blocks in your grammar file in whatever order is most
+ convenient for you:
+
+ %before-header {
+ /* Bison treats this block like a pre-prologue block: it inserts it into
+ * the code file before the contents of the header file. It does *not*
+ * insert it into the header file. This is a good place to put
+ * #include's that you want at the top of your code file. A common
+ * example is '#include "system.h"'. */
+ }
+ %start-header {
+ /* Bison inserts this block into both the header file and the code file.
+ * In both files, the point of insertion is before any Bison-generated
+ * token, semantic type, location type, and class definitions. This is a
+ * good place to define %union dependencies, for example. */
+ }
+ %union {
+ /* Unlike the traditional Yacc prologue blocks, the output order for the
+ * new %*-header blocks is not affected by their declaration position
+ * relative to any %union in the grammar file. */
+ }
+ %end-header {
+ /* Bison inserts this block into both the header file and the code file.
+ * In both files, the point of insertion is after the Bison-generated
+ * definitions. This is a good place to declare or define public
+ * functions or data structures that depend on the Bison-generated
+ * definitions. */
+ }
+ %after-header {
+ /* Bison treats this block like a post-prologue block: it inserts it into
+ * the code file after the contents of the header file. It does *not*
+ * insert it into the header file. This is a good place to declare or
+ * define internal functions or data structures that depend on the
+ * Bison-generated definitions. */
+ }
+
+ If you have multiple occurrences of any one of the above declarations, Bison
+ will concatenate the contents in declaration order.
+
+ [Although we failed to mention this here in the 2.3a release, the prologue
+ alternatives were experimental, and they were rewritten in future versions.]
+
+** The option "--report=look-ahead" has been changed to "--report=lookahead".
+ The old spelling still works, but is not documented and may be removed
+ in a future release.
+
+* Changes in version 2.3, 2006-06-05:
+
+** GLR grammars should now use "YYRECOVERING ()" instead of "YYRECOVERING",
+ for compatibility with LALR(1) grammars.
+
+** It is now documented that any definition of YYSTYPE or YYLTYPE should
+ be to a type name that does not contain parentheses or brackets.
+
+* Changes in version 2.2, 2006-05-19:
+
+** The distribution terms for all Bison-generated parsers now permit
+ using the parsers in nonfree programs. Previously, this permission
+ was granted only for Bison-generated LALR(1) parsers in C.
+
+** %name-prefix changes the namespace name in C++ outputs.
+
+** The C++ parsers export their token_type.
+
+** Bison now allows multiple %union declarations, and concatenates
+ their contents together.
+
+** New warning: unused values
+ Right-hand side symbols whose values are not used are reported,
+ if the symbols have destructors. For instance:
+
+ exp: exp "?" exp ":" exp { $1 ? $1 : $3; }
+ | exp "+" exp
+ ;
+
+ will trigger a warning about $$ and $5 in the first rule, and $3 in
+ the second ($1 is copied to $$ by the default rule). This example
+ most likely contains three errors, and could be rewritten as:
+
+ exp: exp "?" exp ":" exp
+ { $$ = $1 ? $3 : $5; free ($1 ? $5 : $3); free ($1); }
+ | exp "+" exp
+ { $$ = $1 ? $1 : $3; if ($1) free ($3); }
+ ;
+
+ However, if the original actions were really intended, memory leaks
+ and all, the warnings can be suppressed by letting Bison believe the
+ values are used, e.g.:
+
+ exp: exp "?" exp ":" exp { $1 ? $1 : $3; (void) ($$, $5); }
+ | exp "+" exp { $$ = $1; (void) $3; }
+ ;
+
+ If there are mid-rule actions, the warning is issued if no action
+ uses it. The following triggers no warning: $1 and $3 are used.
+
+ exp: exp { push ($1); } '+' exp { push ($3); sum (); };
+
+ The warning is intended to help catching lost values and memory leaks.
+ If a value is ignored, its associated memory typically is not reclaimed.
+
+** %destructor vs. YYABORT, YYACCEPT, and YYERROR.
+ Destructors are now called when user code invokes YYABORT, YYACCEPT,
+ and YYERROR, for all objects on the stack, other than objects
+ corresponding to the right-hand side of the current rule.
+
+** %expect, %expect-rr
+ Incorrect numbers of expected conflicts are now actual errors,
+ instead of warnings.
+
+** GLR, YACC parsers.
+ The %parse-params are available in the destructors (and the
+ experimental printers) as per the documentation.
+
+** Bison now warns if it finds a stray "$" or "@" in an action.
+
+** %require "VERSION"
+ This specifies that the grammar file depends on features implemented
+ in Bison version VERSION or higher.
+
+** lalr1.cc: The token and value types are now class members.
+ The tokens were defined as free form enums and cpp macros. YYSTYPE
+ was defined as a free form union. They are now class members:
+ tokens are enumerations of the "yy::parser::token" struct, and the
+ semantic values have the "yy::parser::semantic_type" type.
+
+ If you do not want or can update to this scheme, the directive
+ '%define "global_tokens_and_yystype" "1"' triggers the global
+ definition of tokens and YYSTYPE. This change is suitable both
+ for previous releases of Bison, and this one.
+
+ If you wish to update, then make sure older version of Bison will
+ fail using '%require "2.2"'.
+
+** DJGPP support added.
+\f
+* Changes in version 2.1, 2005-09-16:
+
+** The C++ lalr1.cc skeleton supports %lex-param.
+
+** Bison-generated parsers now support the translation of diagnostics like
+ "syntax error" into languages other than English. The default
+ language is still English. For details, please see the new
+ Internationalization section of the Bison manual. Software
+ distributors should also see the new PACKAGING file. Thanks to
+ Bruno Haible for this new feature.
+
+** Wording in the Bison-generated parsers has been changed slightly to
+ simplify translation. In particular, the message "memory exhausted"
+ has replaced "parser stack overflow", as the old message was not
+ always accurate for modern Bison-generated parsers.
+
+** Destructors are now called when the parser aborts, for all symbols left
+ behind on the stack. Also, the start symbol is now destroyed after a
+ successful parse. In both cases, the behavior was formerly inconsistent.
+
+** When generating verbose diagnostics, Bison-generated parsers no longer
+ quote the literal strings associated with tokens. For example, for
+ a syntax error associated with '%token NUM "number"' they might
+ print 'syntax error, unexpected number' instead of 'syntax error,
+ unexpected "number"'.
+\f
+* Changes in version 2.0, 2004-12-25:
+
+** Possibly-incompatible changes
+
+ - Bison-generated parsers no longer default to using the alloca function
+ (when available) to extend the parser stack, due to widespread
+ problems in unchecked stack-overflow detection. You can "#define
+ YYSTACK_USE_ALLOCA 1" to require the use of alloca, but please read
+ the manual to determine safe values for YYMAXDEPTH in that case.
+
+ - Error token location.
+ During error recovery, the location of the syntax error is updated
+ to cover the whole sequence covered by the error token: it includes
+ the shifted symbols thrown away during the first part of the error
+ recovery, and the lookahead rejected during the second part.
+
+ - Semicolon changes:
+ . Stray semicolons are no longer allowed at the start of a grammar.
+ . Semicolons are now required after in-grammar declarations.
+
+ - Unescaped newlines are no longer allowed in character constants or
+ string literals. They were never portable, and GCC 3.4.0 has
+ dropped support for them. Better diagnostics are now generated if
+ forget a closing quote.
+
+ - NUL bytes are no longer allowed in Bison string literals, unfortunately.
+
+** New features
+
+ - GLR grammars now support locations.
+
+ - New directive: %initial-action.
+ This directive allows the user to run arbitrary code (including
+ initializing @$) from yyparse before parsing starts.
+
+ - A new directive "%expect-rr N" specifies the expected number of
+ reduce/reduce conflicts in GLR parsers.
+
+ - %token numbers can now be hexadecimal integers, e.g., "%token FOO 0x12d".
+ This is a GNU extension.
+
+ - The option "--report=lookahead" was changed to "--report=look-ahead".
+ [However, this was changed back after 2.3.]
+
+ - Experimental %destructor support has been added to lalr1.cc.
+
+ - New configure option --disable-yacc, to disable installation of the
+ yacc command and -ly library introduced in 1.875 for POSIX conformance.
+
+** Bug fixes
+
+ - For now, %expect-count violations are now just warnings, not errors.
+ This is for compatibility with Bison 1.75 and earlier (when there are
+ reduce/reduce conflicts) and with Bison 1.30 and earlier (when there
+ are too many or too few shift/reduce conflicts). However, in future
+ versions of Bison we plan to improve the %expect machinery so that
+ these violations will become errors again.
+
+ - Within Bison itself, numbers (e.g., goto numbers) are no longer
+ arbitrarily limited to 16-bit counts.
+
+ - Semicolons are now allowed before "|" in grammar rules, as POSIX requires.
+\f
+* Changes in version 1.875, 2003-01-01:
+
+** The documentation license has been upgraded to version 1.2
+ of the GNU Free Documentation License.
+
+** syntax error processing
+
+ - In Yacc-style parsers YYLLOC_DEFAULT is now used to compute error
+ locations too. This fixes bugs in error-location computation.
+
+ - %destructor
+ It is now possible to reclaim the memory associated to symbols
+ discarded during error recovery. This feature is still experimental.
+
+ - %error-verbose
+ This new directive is preferred over YYERROR_VERBOSE.
+
+ - #defining yyerror to steal internal variables is discouraged.
+ It is not guaranteed to work forever.
+
+** POSIX conformance
+
+ - Semicolons are once again optional at the end of grammar rules.
+ This reverts to the behavior of Bison 1.33 and earlier, and improves
+ compatibility with Yacc.
+
+ - "parse error" -> "syntax error"
+ Bison now uniformly uses the term "syntax error"; formerly, the code
+ and manual sometimes used the term "parse error" instead. POSIX
+ requires "syntax error" in diagnostics, and it was thought better to
+ be consistent.
+
+ - The documentation now emphasizes that yylex and yyerror must be
+ declared before use. C99 requires this.
+
+ - Bison now parses C99 lexical constructs like UCNs and
+ backslash-newline within C escape sequences, as POSIX 1003.1-2001 requires.
+
+ - File names are properly escaped in C output. E.g., foo\bar.y is
+ output as "foo\\bar.y".
+
+ - Yacc command and library now available
+ The Bison distribution now installs a "yacc" command, as POSIX requires.
+ Also, Bison now installs a small library liby.a containing
+ implementations of Yacc-compatible yyerror and main functions.
+ This library is normally not useful, but POSIX requires it.
+
+ - Type clashes now generate warnings, not errors.
+
+ - If the user does not define YYSTYPE as a macro, Bison now declares it
+ using typedef instead of defining it as a macro.
+ For consistency, YYLTYPE is also declared instead of defined.
+
+** Other compatibility issues
+
+ - %union directives can now have a tag before the "{", e.g., the
+ directive "%union foo {...}" now generates the C code
+ "typedef union foo { ... } YYSTYPE;"; this is for Yacc compatibility.
+ The default union tag is "YYSTYPE", for compatibility with Solaris 9 Yacc.
+ For consistency, YYLTYPE's struct tag is now "YYLTYPE" not "yyltype".
+ This is for compatibility with both Yacc and Bison 1.35.
+
+ - ";" is output before the terminating "}" of an action, for
+ compatibility with Bison 1.35.
+
+ - Bison now uses a Yacc-style format for conflict reports, e.g.,
+ "conflicts: 2 shift/reduce, 1 reduce/reduce".
+
+ - "yystype" and "yyltype" are now obsolescent macros instead of being
+ typedefs or tags; they are no longer documented and are planned to be
+ withdrawn in a future release.
+
+** GLR parser notes
+
+ - GLR and inline
+ Users of Bison have to decide how they handle the portability of the
+ C keyword "inline".
+
+ - "parsing stack overflow..." -> "parser stack overflow"
+ GLR parsers now report "parser stack overflow" as per the Bison manual.
+
+** %parse-param and %lex-param
+ The macros YYPARSE_PARAM and YYLEX_PARAM provide a means to pass
+ additional context to yyparse and yylex. They suffer from several
+ shortcomings:
+
+ - a single argument only can be added,
+ - their types are weak (void *),
+ - this context is not passed to ancillary functions such as yyerror,
+ - only yacc.c parsers support them.
+
+ The new %parse-param/%lex-param directives provide a more precise control.
+ For instance:
+
+ %parse-param {int *nastiness}
+ %lex-param {int *nastiness}
+ %parse-param {int *randomness}
+
+ results in the following signatures:
+
+ int yylex (int *nastiness);
+ int yyparse (int *nastiness, int *randomness);
+
+ or, if both %pure-parser and %locations are used:
+
+ int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness);
+ int yyparse (int *nastiness, int *randomness);
+
+** Bison now warns if it detects conflicting outputs to the same file,
+ e.g., it generates a warning for "bison -d -o foo.h foo.y" since
+ that command outputs both code and header to foo.h.
+
+** #line in output files
+ - --no-line works properly.
+
+** Bison can no longer be built by a K&R C compiler; it requires C89 or
+ later to be built. This change originally took place a few versions
+ ago, but nobody noticed until we recently asked someone to try
+ building Bison with a K&R C compiler.
+\f
+* Changes in version 1.75, 2002-10-14:
+
+** Bison should now work on 64-bit hosts.
+
+** Indonesian translation thanks to Tedi Heriyanto.
+
+** GLR parsers
+ Fix spurious parse errors.
+
+** Pure parsers
+ Some people redefine yyerror to steal yyparse' private variables.
+ Reenable this trick until an official feature replaces it.
+
+** Type Clashes
+ In agreement with POSIX and with other Yaccs, leaving a default
+ action is valid when $$ is untyped, and $1 typed:
+
+ untyped: ... typed;
+
+ but the converse remains an error:
+
+ typed: ... untyped;
+
+** Values of mid-rule actions
+ The following code:
+
+ foo: { ... } { $$ = $1; } ...
+
+ was incorrectly rejected: $1 is defined in the second mid-rule
+ action, and is equal to the $$ of the first mid-rule action.
+\f
+* Changes in version 1.50, 2002-10-04:
+
+** GLR parsing
+ The declaration
+ %glr-parser
+ causes Bison to produce a Generalized LR (GLR) parser, capable of handling
+ almost any context-free grammar, ambiguous or not. The new declarations
+ %dprec and %merge on grammar rules allow parse-time resolution of
+ ambiguities. Contributed by Paul Hilfinger.
+
+ Unfortunately Bison 1.50 does not work properly on 64-bit hosts
+ like the Alpha, so please stick to 32-bit hosts for now.
+
+** Output Directory
+ When not in Yacc compatibility mode, when the output file was not
+ specified, running "bison foo/bar.y" created "foo/bar.c". It
+ now creates "bar.c".
+
+** Undefined token
+ The undefined token was systematically mapped to 2 which prevented
+ the use of 2 by the user. This is no longer the case.
+
+** Unknown token numbers
+ If yylex returned an out of range value, yyparse could die. This is
+ no longer the case.
+
+** Error token
+ According to POSIX, the error token must be 256.
+ Bison extends this requirement by making it a preference: *if* the
+ user specified that one of her tokens is numbered 256, then error
+ will be mapped onto another number.
+
+** Verbose error messages
+ They no longer report "..., expecting error or..." for states where
+ error recovery is possible.
+
+** End token
+ Defaults to "$end" instead of "$".
+
+** Error recovery now conforms to documentation and to POSIX
+ When a Bison-generated parser encounters a syntax error, it now pops
+ the stack until it finds a state that allows shifting the error
+ token. Formerly, it popped the stack until it found a state that
+ allowed some non-error action other than a default reduction on the
+ error token. The new behavior has long been the documented behavior,
+ and has long been required by POSIX. For more details, please see
+ Paul Eggert, "Reductions during Bison error handling" (2002-05-20)
+ <http://lists.gnu.org/archive/html/bug-bison/2002-05/msg00038.html>.
+
+** Traces
+ Popped tokens and nonterminals are now reported.
+
+** Larger grammars
+ Larger grammars are now supported (larger token numbers, larger grammar
+ size (= sum of the LHS and RHS lengths), larger LALR tables).
+ Formerly, many of these numbers ran afoul of 16-bit limits;
+ now these limits are 32 bits on most hosts.
+
+** Explicit initial rule
+ Bison used to play hacks with the initial rule, which the user does
+ not write. It is now explicit, and visible in the reports and
+ graphs as rule 0.
+
+** Useless rules
+ Before, Bison reported the useless rules, but, although not used,
+ included them in the parsers. They are now actually removed.
+
+** Useless rules, useless nonterminals
+ They are now reported, as a warning, with their locations.
+
+** Rules never reduced
+ Rules that can never be reduced because of conflicts are now
+ reported.
+
+** Incorrect "Token not used"
+ On a grammar such as
+
+ %token useless useful
+ %%
+ exp: '0' %prec useful;
+
+ where a token was used to set the precedence of the last rule,
+ bison reported both "useful" and "useless" as useless tokens.
+
+** Revert the C++ namespace changes introduced in 1.31
+ as they caused too many portability hassles.
+
+** Default locations
+ By an accident of design, the default computation of @$ was
+ performed after another default computation was performed: @$ = @1.
+ The latter is now removed: YYLLOC_DEFAULT is fully responsible of
+ the computation of @$.
+
+** Token end-of-file
+ The token end of file may be specified by the user, in which case,
+ the user symbol is used in the reports, the graphs, and the verbose
+ error messages instead of "$end", which remains being the default.
+ For instance
+ %token MYEOF 0
+ or
+ %token MYEOF 0 "end of file"
+
+** Semantic parser
+ This old option, which has been broken for ages, is removed.
+
+** New translations
+ Brazilian Portuguese, thanks to Alexandre Folle de Menezes.
+ Croatian, thanks to Denis Lackovic.
+
+** Incorrect token definitions
+ When given
+ %token 'a' "A"
+ bison used to output
+ #define 'a' 65
+
+** Token definitions as enums
+ Tokens are output both as the traditional #define's, and, provided
+ the compiler supports ANSI C or is a C++ compiler, as enums.
+ This lets debuggers display names instead of integers.
+
+** Reports
+ In addition to --verbose, bison supports --report=THINGS, which
+ produces additional information:
+ - itemset
+ complete the core item sets with their closure
+ - lookahead [changed to "look-ahead" in 1.875e through 2.3, but changed back]
+ explicitly associate lookahead tokens to items
+ - solved
+ describe shift/reduce conflicts solving.
+ Bison used to systematically output this information on top of
+ the report. Solved conflicts are now attached to their states.
+
+** Type clashes
+ Previous versions don't complain when there is a type clash on
+ the default action if the rule has a mid-rule action, such as in:
+
+ %type <foo> bar
+ %%
+ bar: '0' {} '0';
+
+ This is fixed.
+
+** GNU M4 is now required when using Bison.
+\f
+* Changes in version 1.35, 2002-03-25:
+
+** C Skeleton
+ Some projects use Bison's C parser with C++ compilers, and define
+ YYSTYPE as a class. The recent adjustment of C parsers for data
+ alignment and 64 bit architectures made this impossible.
+
+ Because for the time being no real solution for C++ parser
+ generation exists, kludges were implemented in the parser to
+ maintain this use. In the future, when Bison has C++ parsers, this
+ kludge will be disabled.
+
+ This kludge also addresses some C++ problems when the stack was
+ extended.
+\f
+* Changes in version 1.34, 2002-03-12:
+
+** File name clashes are detected
+ $ bison foo.y -d -o foo.x
+ fatal error: header and parser would both be named "foo.x"
+
+** A missing ";" at the end of a rule triggers a warning
+ In accordance with POSIX, and in agreement with other
+ Yacc implementations, Bison will mandate this semicolon in the near
+ future. This eases the implementation of a Bison parser of Bison
+ grammars by making this grammar LALR(1) instead of LR(2). To
+ facilitate the transition, this release introduces a warning.
+
+** Revert the C++ namespace changes introduced in 1.31, as they caused too
+ many portability hassles.
+
+** DJGPP support added.
+
+** Fix test suite portability problems.
+\f
+* Changes in version 1.33, 2002-02-07:
+
+** Fix C++ issues
+ Groff could not be compiled for the definition of size_t was lacking
+ under some conditions.
+
+** Catch invalid @n
+ As is done with $n.
+\f
+* Changes in version 1.32, 2002-01-23:
+
+** Fix Yacc output file names
+
+** Portability fixes
+
+** Italian, Dutch translations
+\f
+* Changes in version 1.31, 2002-01-14:
+
+** Many Bug Fixes
+
+** GNU Gettext and %expect
+ GNU Gettext asserts 10 s/r conflicts, but there are 7. Now that
+ Bison dies on incorrect %expectations, we fear there will be
+ too many bug reports for Gettext, so _for the time being_, %expect
+ does not trigger an error when the input file is named "plural.y".
+
+** Use of alloca in parsers
+ If YYSTACK_USE_ALLOCA is defined to 0, then the parsers will use
+ malloc exclusively. Since 1.29, but was not NEWS'ed.
+
+ alloca is used only when compiled with GCC, to avoid portability
+ problems as on AIX.
+
+** yyparse now returns 2 if memory is exhausted; formerly it dumped core.
+
+** When the generated parser lacks debugging code, YYDEBUG is now 0
+ (as POSIX requires) instead of being undefined.
+
+** User Actions
+ Bison has always permitted actions such as { $$ = $1 }: it adds the
+ ending semicolon. Now if in Yacc compatibility mode, the semicolon
+ is no longer output: one has to write { $$ = $1; }.
+
+** Better C++ compliance
+ The output parsers try to respect C++ namespaces.
+ [This turned out to be a failed experiment, and it was reverted later.]
+
+** Reduced Grammars
+ Fixed bugs when reporting useless nonterminals.
+
+** 64 bit hosts
+ The parsers work properly on 64 bit hosts.
+
+** Error messages
+ Some calls to strerror resulted in scrambled or missing error messages.
+
+** %expect
+ When the number of shift/reduce conflicts is correct, don't issue
+ any warning.
+
+** The verbose report includes the rule line numbers.
+
+** Rule line numbers are fixed in traces.
+
+** Swedish translation
+
+** Parse errors
+ Verbose parse error messages from the parsers are better looking.
+ Before: parse error: unexpected `'/'', expecting `"number"' or `'-'' or `'(''
+ Now: parse error: unexpected '/', expecting "number" or '-' or '('
+
+** Fixed parser memory leaks.
+ When the generated parser was using malloc to extend its stacks, the
+ previous allocations were not freed.
+
+** Fixed verbose output file.
+ Some newlines were missing.
+ Some conflicts in state descriptions were missing.
+
+** Fixed conflict report.
+ Option -v was needed to get the result.
+
+** %expect
+ Was not used.
+ Mismatches are errors, not warnings.
+
+** Fixed incorrect processing of some invalid input.
+
+** Fixed CPP guards: 9foo.h uses BISON_9FOO_H instead of 9FOO_H.
+
+** Fixed some typos in the documentation.
+
+** %token MY_EOF 0 is supported.
+ Before, MY_EOF was silently renumbered as 257.
+
+** doc/refcard.tex is updated.
+
+** %output, %file-prefix, %name-prefix.
+ New.
+
+** --output
+ New, aliasing "--output-file".
+\f
+* Changes in version 1.30, 2001-10-26:
+
+** "--defines" and "--graph" have now an optional argument which is the
+ output file name. "-d" and "-g" do not change; they do not take any
+ argument.
+
+** "%source_extension" and "%header_extension" are removed, failed
+ experiment.
+
+** Portability fixes.
+\f
+* Changes in version 1.29, 2001-09-07:
+
+** The output file does not define const, as this caused problems when used
+ with common autoconfiguration schemes. If you still use ancient compilers
+ that lack const, compile with the equivalent of the C compiler option
+ "-Dconst=". Autoconf's AC_C_CONST macro provides one way to do this.
+
+** Added "-g" and "--graph".
+
+** The Bison manual is now distributed under the terms of the GNU FDL.
+
+** The input and the output files has automatically a similar extension.
+
+** Russian translation added.
+
+** NLS support updated; should hopefully be less troublesome.
+
+** Added the old Bison reference card.
+
+** Added "--locations" and "%locations".
+
+** Added "-S" and "--skeleton".
+
+** "%raw", "-r", "--raw" is disabled.
+
+** Special characters are escaped when output. This solves the problems
+ of the #line lines with path names including backslashes.
+
+** New directives.
+ "%yacc", "%fixed_output_files", "%defines", "%no_parser", "%verbose",
+ "%debug", "%source_extension" and "%header_extension".
+
+** @$
+ Automatic location tracking.
+\f
+* Changes in version 1.28, 1999-07-06:
+
+** Should compile better now with K&R compilers.
+
+** Added NLS.
+
+** Fixed a problem with escaping the double quote character.
+
+** There is now a FAQ.
+\f
+* Changes in version 1.27:
+
+** The make rule which prevented bison.simple from being created on
+ some systems has been fixed.
+\f
+* Changes in version 1.26:
+
+** Bison now uses Automake.
+
+** New mailing lists: <bug-bison@gnu.org> and <help-bison@gnu.org>.
+
+** Token numbers now start at 257 as previously documented, not 258.
+
+** Bison honors the TMPDIR environment variable.
+
+** A couple of buffer overruns have been fixed.
+
+** Problems when closing files should now be reported.
+
+** Generated parsers should now work even on operating systems which do
+ not provide alloca().
+\f
+* Changes in version 1.25, 1995-10-16:
+
+** Errors in the input grammar are not fatal; Bison keeps reading
+the grammar file, and reports all the errors found in it.
+
+** Tokens can now be specified as multiple-character strings: for
+example, you could use "<=" for a token which looks like <=, instead
+of choosing a name like LESSEQ.
+
+** The %token_table declaration says to write a table of tokens (names
+and numbers) into the parser file. The yylex function can use this
+table to recognize multiple-character string tokens, or for other
+purposes.
+
+** The %no_lines declaration says not to generate any #line preprocessor
+directives in the parser file.
+
+** The %raw declaration says to use internal Bison token numbers, not
+Yacc-compatible token numbers, when token names are defined as macros.
+
+** The --no-parser option produces the parser tables without including
+the parser engine; a project can now use its own parser engine.
+The actions go into a separate file called NAME.act, in the form of
+a switch statement body.
+\f
+* Changes in version 1.23:
+
+The user can define YYPARSE_PARAM as the name of an argument to be
+passed into yyparse. The argument should have type void *. It should
+actually point to an object. Grammar actions can access the variable
+by casting it to the proper pointer type.
+
+Line numbers in output file corrected.
+\f
+* Changes in version 1.22:
+
+--help option added.
+\f
+* Changes in version 1.20:
+
+Output file does not redefine const for C++.

+Packaging hints for binary package distributors
+===============================================
+
+Although the source of the bison package comes as a single package,
+in distributions of binary packages the installed files should
+be split into two packages:
+
+ bison-runtime
+ Contents: Runtime libraries and programs.
+ Audience: Anyone who wants to run internationalized programs
+ that contain Bison-generated parsers.
+
+ bison
+ Contents: Tools and documentation for developers that use Bison.
+ Audience: Anyone who wants to develop programs that use parsers.
+ Dependencies: requires bison-runtime.
+
+The 'bison-runtime' binary package is much smaller than the 'bison'
+binary package. It should be included in any distribution that
+contains localized programs that use the diagnostics contained in
+Bison-generated parsers.
+
+If you want to install both packages at the same time, you simply do
+at the toplevel directory:
+
+ ./configure
+ make
+ make install
+
+After installation, the file
+
+ $prefix/share/locale/*/LC_MESSAGES/bison-runtime.mo
+
+belongs to the bison-runtime package; all other installed files belong
+to the bison package.

+This package contains the GNU Bison parser generator.
+
+* Installation
+** Build
+See the file INSTALL for generic compilation and installation
+instructions.
+
+Bison requires GNU m4 1.4.6 or later. See:
+
+ ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz
+
+** Internationalization
+Bison supports two catalogues: one for Bison itself (i.e., for the
+maintainer-side parser generation), and one for the generated parsers
+(i.e., for the user-side parser execution). The requirements between
+both differ: bison needs ngettext, the generated parsers do not. To
+simplify the build system, neither are installed if ngettext is not
+supported, even if generated parsers could have been localized. See
+http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html for
+more details.
+
+* Questions
+See the section FAQ in the documentation (doc/bison.info) for
+frequently asked questions. The documentation is also available in
+PDF and HTML, provided you have a recent version of Texinfo installed:
+run "make pdf" or "make html".
+
+If you have questions about using Bison and the documentation does
+not answer them, please send mail to <help-bison@gnu.org>.
+
+* Bug reports
+Please send bug reports to <bug-bison@gnu.org>. Please include the
+version number from `bison --version', and a complete, self-contained
+test case in each bug report.
+
+* Copyright statements
+For any copyright year range specified as YYYY-ZZZZ in this package,
+note that the range specifies every single year in that closed interval.

+Here are most of the steps we (maintainers) follow when making a release.
+
+* Start from a clean, up-to-date git directory on "master":
+
+ make -k maintainer-clean || { ./configure && make maintainer-clean; }
+ git checkout master
+ git pull origin master
+
+* Ensure that the latest stable versions of autoconf, automake, etc.
+ are in your PATH. See the buildreq list in bootstrap.conf for
+ the complete list of tools.
+
+* Ensure that you have no uncommitted diffs. This should produce no
+ output:
+
+ git diff
+
+* Ensure that you've pushed all changes that belong in the release:
+
+ git push origin master
+
+* Check that the NixOS/Hydra autobuilder is reporting all is well:
+
+ http://hydra.nixos.org/jobset/gnu/bison-master
+
+* Run the following command to download any new translations:
+
+ ./bootstrap && ./configure
+
+* Pre-release testing: ensure that the following command succeeds:
+
+ make check syntax-check distcheck
+
+* From top_srcdir, run:
+
+ build-aux/do-release-commit-and-tag X.Y stable
+
+ in order to (i) set the date, version number, and release type
+ [stable/alpha/beta] on line 3 of NEWS, (ii) commit that, and (iii) tag the
+ release. See --help if you need options such as:
+
+ build-aux/do-release-commit-and-tag --branch=maint -C _build X.Y.Z stable
+
+* Run the following to create release tarballs. Your choice selects the
+ corresponding upload-to destination in the emitted gnupload command.
+ The different destinations are specified in cfg.mk. See the definitions
+ of gnu_ftp_host-{alpha,beta,stable}.
+
+ # "TYPE" must be stable, beta or alpha
+ make TYPE
+
+* Test the tarball. Copy it to a few odd-ball systems and ensure that
+ it builds and passes all tests.
+
+* While that's happening, write the release announcement that you will
+ soon post. Start with the template, $HOME/announce-bison-X.Y
+ that was just created by that "make" command.
+
+Once all the builds and tests have passed,
+
+* Run the gnupload command that was suggested by your "make TYPE" run above.
+
+* Wait a few minutes (maybe up to 30?) and then use the release URLs to
+ download all tarball/signature pairs and use gpg --verify to ensure
+ that they're all valid.
+
+* Push the NEWS-updating changes and the new tag:
+
+ v=$(cat .prev-version)
+ git push origin master tag v$v
+
+* Announce it on Savannah first, so you can include the savannah.org
+ announcement link in the email message.
+
+ From here:
+
+ https://savannah.gnu.org/projects/bison/
+
+ click on "Submit news", then write something like the following:
+ (If there is no such button, then enable "News" for the project via
+ the "Main->Select Features" menu item, or via this link:
+
+ https://savannah.gnu.org/project/admin/editgroupfeatures.php?group=bison
+
+ )
+
+ Subject: bison-X.Y released [stable]
+ +verbatim+
+ ...paste the announcement here...
+ -verbatim-
+
+ Then go here to approve it:
+
+ https://savannah.gnu.org/news/approve.php?group=bison
+
+* Send the announcement email message.
+
+* After each non-alpha release, update the on-line manual accessible via
+
+ http://www.gnu.org/software/bison/manual/
+
+ by running this from top_srcdir:
+
+ build-aux/gnu-web-doc-update
+
+ possibly with "-C <BUILDDIR>"

+* Short term
+** Variable names.
+What should we name `variant' and `lex_symbol'?
+
+** Use b4_symbol in all the skeleton
+Move its definition in the more standard places and deploy it in other
+skeletons. Then remove the older system, including the tables
+generated by output.c
+
+** Update the documentation on gnu.org
+
+** Get rid of fake #lines [Bison: ...]
+Possibly as simple as checking whether the column number is nonnegative.
+
+I have seen messages like the following from GCC.
+
+<built-in>:0: fatal error: opening dependency file .deps/libltdl/argz.Tpo: No such file or directory
+
+
+** Discuss about %printer/%destroy in the case of C++.
+It would be very nice to provide the symbol classes with an operator<<
+and a destructor. Unfortunately the syntax we have chosen for
+%destroy and %printer make them hard to reuse. For instance, the user
+is invited to write something like
+
+ %printer { debug_stream() << $$; } <my_type>;
+
+which is hard to reuse elsewhere since it wants to use
+"debug_stream()" to find the stream to use. The same applies to
+%destroy: we told the user she could use the members of the Parser
+class in the printers/destructors, which is not good for an operator<<
+since it is no longer bound to a particular parser, it's just a
+(standalone symbol).
+
+** Rename LR0.cc
+as lr0.cc, why upper case?
+
+** bench several bisons.
+Enhance bench.pl with %b to run different bisons.
+
+* Various
+** Warnings
+Warnings about type tags that are used in printer and dtors, but not
+for symbols?
+
+** YYERRCODE
+Defined to 256, but not used, not documented. Probably the token
+number for the error token, which POSIX wants to be 256, but which
+Bison might renumber if the user used number 256. Keep fix and doc?
+Throw away?
+
+Also, why don't we output the token name of the error token in the
+output? It is explicitly skipped:
+
+ /* Skip error token and tokens without identifier. */
+ if (sym != errtoken && id)
+
+Of course there are issues with name spaces, but if we disable we have
+something which seems to be more simpler and more consistent instead
+of the special case YYERRCODE.
+
+ enum yytokentype {
+ error = 256,
+ // ...
+ };
+
+
+We could (should?) also treat the case of the undef_token, which is
+numbered 257 for yylex, and 2 internal. Both appear for instance in
+toknum:
+
+ const unsigned short int
+ parser::yytoken_number_[] =
+ {
+ 0, 256, 257, 258, 259, 260, 261, 262, 263, 264,
+
+while here
+
+ enum yytokentype {
+ TOK_EOF = 0,
+ TOK_EQ = 258,
+
+so both 256 and 257 are "mysterious".
+
+ const char*
+ const parser::yytname_[] =
+ {
+ "\"end of command\"", "error", "$undefined", "\"=\"", "\"break\"",
+
+
+** YYFAIL
+It is seems to be *really* obsolete now, shall we remove it?
+
+** yychar == yyempty_
+The code in yyerrlab reads:
+
+ if (yychar <= YYEOF)
+ {
+ /* Return failure if at end of input. */
+ if (yychar == YYEOF)
+ YYABORT;
+ }
+
+There are only two yychar that can be <= YYEOF: YYEMPTY and YYEOF.
+But I can't produce the situation where yychar is YYEMPTY here, is it
+really possible? The test suite does not exercise this case.
+
+This shows that it would be interesting to manage to install skeleton
+coverage analysis to the test suite.
+
+** Table definitions
+It should be very easy to factor the definition of the various tables,
+including the separation bw declaration and definition. See for
+instance b4_table_define in lalr1.cc. This way, we could even factor
+C vs. C++ definitions.
+
+* From lalr1.cc to yacc.c
+** Single stack
+Merging the three stacks in lalr1.cc simplified the code, prompted for
+other improvements and also made it faster (probably because memory
+management is performed once instead of three times). I suggest that
+we do the same in yacc.c.
+
+** yysyntax_error
+The code bw glr.c and yacc.c is really alike, we can certainly factor
+some parts.
+
+
+* Report
+
+** Figures
+Some statistics about the grammar and the parser would be useful,
+especially when asking the user to send some information about the
+grammars she is working on. We should probably also include some
+information about the variables (I'm not sure for instance we even
+specify what LR variant was used).
+
+** GLR
+How would Paul like to display the conflicted actions? In particular,
+what when two reductions are possible on a given lookahead token, but one is
+part of $default. Should we make the two reductions explicit, or just
+keep $default? See the following point.
+
+** Disabled Reductions
+See `tests/conflicts.at (Defaulted Conflicted Reduction)', and decide
+what we want to do.
+
+** Documentation
+Extend with error productions. The hard part will probably be finding
+the right rule so that a single state does not exhibit too many yet
+undocumented ``features''. Maybe an empty action ought to be
+presented too. Shall we try to make a single grammar with all these
+features, or should we have several very small grammars?
+
+** --report=conflict-path
+Provide better assistance for understanding the conflicts by providing
+a sample text exhibiting the (LALR) ambiguity. See the paper from
+DeRemer and Penello: they already provide the algorithm.
+
+** Statically check for potential ambiguities in GLR grammars. See
+<http://www.i3s.unice.fr/~schmitz/papers.html#expamb> for an approach.
+
+
+* Extensions
+
+** $-1
+We should find a means to provide an access to values deep in the
+stack. For instance, instead of
+
+ baz: qux { $$ = $<foo>-1 + $<bar>0 + $1; }
+
+we should be able to have:
+
+ foo($foo) bar($bar) baz($bar): qux($qux) { $baz = $foo + $bar + $qux; }
+
+Or something like this.
+
+** %if and the like
+It should be possible to have %if/%else/%endif. The implementation is
+not clear: should it be lexical or syntactic. Vadim Maslow thinks it
+must be in the scanner: we must not parse what is in a switched off
+part of %if. Akim Demaille thinks it should be in the parser, so as
+to avoid falling into another CPP mistake.
+
+** XML Output
+There are couple of available extensions of Bison targeting some XML
+output. Some day we should consider including them. One issue is
+that they seem to be quite orthogonal to the parsing technique, and
+seem to depend mostly on the possibility to have some code triggered
+for each reduction. As a matter of fact, such hooks could also be
+used to generate the yydebug traces. Some generic scheme probably
+exists in there.
+
+XML output for GNU Bison and gcc
+ http://www.cs.may.ie/~jpower/Research/bisonXML/
+
+XML output for GNU Bison
+ http://yaxx.sourceforge.net/
+
+* Unit rules
+Maybe we could expand unit rules, i.e., transform
+
+ exp: arith | bool;
+ arith: exp '+' exp;
+ bool: exp '&' exp;
+
+into
+
+ exp: exp '+' exp | exp '&' exp;
+
+when there are no actions. This can significantly speed up some
+grammars. I can't find the papers. In particular the book `LR
+parsing: Theory and Practice' is impossible to find, but according to
+`Parsing Techniques: a Practical Guide', it includes information about
+this issue. Does anybody have it?
+
+
+
+* Documentation
+
+** History/Bibliography
+Some history of Bison and some bibliography would be most welcome.
+Are there any Texinfo standards for bibliography?
+
+* Coding system independence
+Paul notes:
+
+ Currently Bison assumes 8-bit bytes (i.e. that UCHAR_MAX is
+ 255). It also assumes that the 8-bit character encoding is
+ the same for the invocation of 'bison' as it is for the
+ invocation of 'cc', but this is not necessarily true when
+ people run bison on an ASCII host and then use cc on an EBCDIC
+ host. I don't think these topics are worth our time
+ addressing (unless we find a gung-ho volunteer for EBCDIC or
+ PDP-10 ports :-) but they should probably be documented
+ somewhere.
+
+ More importantly, Bison does not currently allow NUL bytes in
+ tokens, either via escapes (e.g., "x\0y") or via a NUL byte in
+ the source code. This should get fixed.
+
+* --graph
+Show reductions.
+
+* Broken options ?
+** %token-table
+** Skeleton strategy
+Must we keep %token-table?
+
+* Precedence
+
+** Partial order
+It is unfortunate that there is a total order for precedence. It
+makes it impossible to have modular precedence information. We should
+move to partial orders (sounds like series/parallel orders to me).
+
+** RR conflicts
+See if we can use precedence between rules to solve RR conflicts. See
+what POSIX says.
+
+
+* $undefined
+From Hans:
+- If the Bison generated parser experiences an undefined number in the
+character range, that character is written out in diagnostic messages, an
+addition to the $undefined value.
+
+Suggest: Change the name $undefined to undefined; looks better in outputs.
+
+
+* Default Action
+From Hans:
+- For use with my C++ parser, I transported the "switch (yyn)" statement
+that Bison writes to the bison.simple skeleton file. This way, I can remove
+the current default rule $$ = $1 implementation, which causes a double
+assignment to $$ which may not be OK under C++, replacing it with a
+"default:" part within the switch statement.
+
+Note that the default rule $$ = $1, when typed, is perfectly OK under C,
+but in the C++ implementation I made, this rule is different from
+$<type_name>$ = $<type_name>1. I therefore think that one should implement
+a Bison option where every typed default rule is explicitly written out
+(same typed ruled can of course be grouped together).
+
+* Pre and post actions.
+From: Florian Krohm <florian@edamail.fishkill.ibm.com>
+Subject: YYACT_EPILOGUE
+To: bug-bison@gnu.org
+X-Sent: 1 week, 4 days, 14 hours, 38 minutes, 11 seconds ago
+
+The other day I had the need for explicitly building the parse tree. I
+used %locations for that and defined YYLLOC_DEFAULT to call a function
+that returns the tree node for the production. Easy. But I also needed
+to assign the S-attribute to the tree node. That cannot be done in
+YYLLOC_DEFAULT, because it is invoked before the action is executed.
+The way I solved this was to define a macro YYACT_EPILOGUE that would
+be invoked after the action. For reasons of symmetry I also added
+YYACT_PROLOGUE. Although I had no use for that I can envision how it
+might come in handy for debugging purposes.
+All is needed is to add
+
+#if YYLSP_NEEDED
+ YYACT_EPILOGUE (yyval, (yyvsp - yylen), yylen, yyloc, (yylsp - yylen));
+#else
+ YYACT_EPILOGUE (yyval, (yyvsp - yylen), yylen);
+#endif
+
+at the proper place to bison.simple. Ditto for YYACT_PROLOGUE.
+
+I was wondering what you think about adding YYACT_PROLOGUE/EPILOGUE
+to bison. If you're interested, I'll work on a patch.
+
+* Better graphics
+Equip the parser with a means to create the (visual) parse tree.
+
+* Complaint submessage indentation.
+We already have an implementation that works fairly well for named
+reference messages, but it would be nice to use it consistently for all
+submessages from Bison. For example, the "previous definition"
+submessage or the list of correct values for a %define variable might
+look better with indentation.
+
+However, the current implementation makes the assumption that the
+location printed on the first line is not usually much shorter than the
+locations printed on the submessage lines that follow. That assumption
+may not hold true as often for some kinds of submessages especially if
+we ever support multiple grammar files.
+
+Here's a proposal for how a new implementation might look:

+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:

+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because

+# However there are other variables, like CC, which are often used in

+- a version-controlled .prev-version file
+- a NEWS file, with line 3 identical to this:
+$noteworthy_stub

+usage="Usage: $prog [OPTION]... PACKAGE MANUAL-TITLE
+
+Generate various output formats from PACKAGE.texinfo (or .texi or .txi) source.
+See the GNU Maintainers document for a more extensive discussion:
+ http://www.gnu.org/prep/maintain_toc.html
+
+Options:
+ -s SRCFILE read Texinfo from SRCFILE, instead of PACKAGE.{texinfo|texi|txi}
+ -o OUTDIR write files into OUTDIR, instead of manual/.
+ --email ADR use ADR as contact in generated web pages.
+ --docbook convert to DocBook too (xml, txt, html, pdf and ps).
+ --html ARG pass indicated ARG to makeinfo or texi2html for HTML targets.
+ --texi2html use texi2html to generate HTML targets.
+ --help display this help and exit successfully.
+ --version display version information and exit successfully.
+
+Simple example: $prog --email bug-gnu-emacs@gnu.org emacs \"GNU Emacs Manual\"
+
+Typical sequence:
+ cd PACKAGESOURCE/doc
+ wget \"$scripturl\"
+ wget \"$templateurl\"
+ $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"
+
+Output will be in a new subdirectory \"manual\" (by default, use -o OUTDIR
+to override). Move all the new files into your web CVS tree, as
+explained in the Web Pages node of maintain.texi.
+
+Please use the --email ADDRESS option to specify your bug-reporting
+address in the generated HTML pages.
+
+MANUAL-TITLE is included as part of the HTML <title> of the overall
+manual/index.html file. It should include the name of the package being
+documented. manual/index.html is created by substitution from the file
+$GENDOCS_TEMPLATE_DIR/gendocs_template. (Feel free to modify the
+generic template for your own purposes.)
+
+If you have several manuals, you'll need to run this script several
+times with different MANUAL values, specifying a different output
+directory with -o each time. Then write (by hand) an overall index.html
+with links to them all.
+
+If a manual's Texinfo sources are spread across several directories,
+first copy or symlink all Texinfo sources into a single directory.
+(Part of the script's work is to make a tar.gz of the sources.)
+
+You can set the environment variables MAKEINFO, TEXI2DVI, TEXI2HTML, and
+DVIPS to control the programs that get executed, and
+GENDOCS_TEMPLATE_DIR to control where the gendocs_template file is
+looked for. With --docbook, the environment variables DOCBOOK2HTML,
+DOCBOOK2PDF, DOCBOOK2PS, and DOCBOOK2TXT are also respected.
+
+By default, makeinfo and texi2dvi are run in the default (English)
+locale, since that's the language of most Texinfo manuals. If you
+happen to have a non-English manual and non-English web site, see the
+SETLANG setting in the source.
+
+Email bug reports or enhancement requests to bug-texinfo@gnu.org.

+Usage: $ME [OPTIONS] [ARGS]
+
+Convert git log output to ChangeLog format. If present, any ARGS
+are passed to "git log". To avoid ARGS being parsed as options to
+$ME, they may be preceded by '--'.
+
+OPTIONS:
+
+ --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+ makes a change to SHA1's commit log text or metadata.
+ --append-dot append a dot to the first line of each commit message if
+ there is no other punctuation or blank at the end.
+ --no-cluster never cluster commit messages under the same date/author
+ header; the default is to cluster adjacent commit messages
+ if their headers are the same and neither commit message
+ contains multiple paragraphs.
+ --srcdir=DIR the root of the source tree, containing the '.git' directory.
+ --since=DATE convert only the logs since DATE;
+ the default is to convert all log entries.
+ --format=FMT set format string for commit subject and body;
+ see 'man git-log' for the list of format metacharacters;
+ the default is '%s%n%b%n'
+ --strip-tab remove one additional leading TAB from commit message lines.
+ --strip-cherry-pick remove data inserted by "git cherry-pick";
+ this includes the "cherry picked from commit ..." line,
+ and the possible final "Conflicts:" paragraph.
+ --help display this help and exit
+ --version output version information and exit
+
+EXAMPLE:
+
+ $ME --since=2008-01-01 > ChangeLog
+ $ME -- -n 5 foo > last-5-commits-to-branch-foo
+
+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line. They are not copied to the output.
+
+ Copyright-paperwork-exempt: Yes
+ Append the "(tiny change)" notation to the usual "date name email"
+ ChangeLog header to mark a change that does not require a copyright
+ assignment.
+ Co-authored-by: Joe User <user\@example.com>
+ List the specified name and email address on a second
+ ChangeLog header, denoting a co-author.
+ Signed-off-by: Joe User <user\@example.com>
+ These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code. Pairs must be separated by one or
+more blank line.
+
+Here is sample input for use with --amend=FILE, from coreutils:
+
+3a169f4c5d9159283548178668d2fae6fced3030
+# fix typo in title:

+
+Sign all FILES, and process them at selected destinations according to CMD.
+<http://www.gnu.org/prep/maintain/html_node/Automated-FTP-Uploads.html>
+explains further.
+
+Commands:
+ --delete delete FILES from destination
+ --symlink create symbolic links
+ --rmsymlink remove symbolic links
+ -- treat the remaining arguments as files to upload
+
+Options:
+ --help print this help text and exit
+ --to DEST specify one destination for FILES
+ (multiple --to options are allowed)
+ --user NAME sign with key NAME
+ --replace allow replacements of existing files
+ --symlink-regex[=EXPR] use sed script EXPR to compute symbolic link names
+ --dry-run do nothing, show what would have been done
+ (including the constructed directive file)
+ --version output version information and exit
+
+If --symlink-regex is given without EXPR, then the link target name
+is created by replacing the version information with '-latest', e.g.:
+
+ foo-1.3.4.tar.gz -> foo-latest.tar.gz
+
+Recognized destinations are:
+ alpha.gnu.org:DIRECTORY
+ savannah.gnu.org:DIRECTORY
+ savannah.nongnu.org:DIRECTORY
+ ftp.gnu.org:DIRECTORY
+ build directive files and upload files by FTP
+ download.gnu.org.ua:{alpha|ftp}/DIRECTORY
+ build directive files and upload files by SFTP
+ [user@]host:DIRECTORY upload files with scp
+
+Options and commands are applied in order. If the file $conffile exists
+in the current working directory, its contents are prepended to the
+actual command line options. Use this to keep your defaults. Comments
+(#) and empty lines in $conffile are allowed.
+
+Examples:
+1. Upload foobar-1.0.tar.gz to ftp.gnu.org:
+ gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz
+
+2. Upload foobar-1.0.tar.gz and foobar-1.0.tar.xz to ftp.gnu.org:
+ gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+3. Same as above, and also create symbolic links to foobar-latest.tar.*:
+ gnupload --to ftp.gnu.org:foobar \\
+ --symlink-regex \\
+ foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+4. Upload foobar-0.9.90.tar.gz to two sites:
+ gnupload --to alpha.gnu.org:foobar \\
+ --to sources.redhat.com:~ftp/pub/foobar \\
+ foobar-0.9.90.tar.gz
+
+5. Delete oopsbar-0.9.91.tar.gz and upload foobar-0.9.91.tar.gz
+ (the -- terminates the list of files to delete):
+ gnupload --to alpha.gnu.org:foobar \\
+ --to sources.redhat.com:~ftp/pub/foobar \\
+ --delete oopsbar-0.9.91.tar.gz \\
+ -- foobar-0.9.91.tar.gz
+
+gnupload uses the ncftpput program to do the transfers; if you don't
+happen to have an ncftp package installed, the ncftpput-ftp script in
+the build-aux/ directory of the gnulib package
+(http://savannah.gnu.org/projects/gnulib) may serve as a replacement.

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+ for FUNCTION which will then trigger a compiler warning containing
+ the text of "literal string" anywhere that function is called, if
+ supported by the compiler. If the compiler does not support this
+ feature, the macro expands to an unused extern declaration.
+
+ This macro is useful for marking a function as a potential
+ portability trap, with the intent that "literal string" include
+ instructions on the replacement function that should be used
+ instead. However, one of the reasons that a function is a
+ portability trap is if it has the wrong signature. Declaring
+ FUNCTION with a different signature in C is a compilation error, so
+ this macro must use the same type as any existing declaration so
+ that programs that avoid the problematic FUNCTION do not fail to
+ compile merely because they included a header that poisoned the
+ function. But this implies that _GL_WARN_ON_USE is only safe to
+ use if FUNCTION is known to already have a declaration. Use of
+ this macro implies that there must not be any other macro hiding
+ the declaration of FUNCTION; but undefining FUNCTION first is part
+ of the poisoning process anyway (although for symbols that are
+ provided only via a macro, the result is a compilation error rather
+ than a warning containing "literal string"). Also note that in
+ C++, it is only safe to use if FUNCTION has no overloads.
+
+ For an example, it is possible to poison 'getline' by:
+ - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
+ [getline]) in configure.ac, which potentially defines
+ HAVE_RAW_DECL_GETLINE
+ - adding this code to a header that wraps the system <stdio.h>:
+ #undef getline
+ #if HAVE_RAW_DECL_GETLINE
+ _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+ "not universally present; use the gnulib module getline");
+ #endif
+
+ It is not possible to directly poison global variables. But it is
+ possible to write a wrapper accessor function, and poison that
+ (less common usage, like &environ, will cause a compilation error
+ rather than issue the nice warning, but the end result of informing
+ the developer about their portability problem is still achieved):
+ #if HAVE_RAW_DECL_ENVIRON
+ static inline char ***rpl_environ (void) { return &environ; }
+ _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");

+% of date, so if that's what you're using, please check.

+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution. For a simple
+% manual foo.texi, however, you can get away with this:
+% tex foo.texi
+% texindex foo.??
+% tex foo.texi
+% tex foo.texi
+% dvips foo.dvi -o # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent. You can get the existing language-specific files from the
+% full Texinfo distribution.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble. Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+% @multitable @columnfractions .25 .3 .45
+% @item ...
+%
+% Numbers following @columnfractions are the percent of the total
+% current hsize to be used for each column. You may use as many
+% columns as desired.
+
+
+% Or use a template:
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item ...
+% using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item first col stuff @tab second col stuff @tab third col
+% @item
+% first col stuff
+% @tab
+% second col stuff
+% @tab
+% third col
+% @item first col stuff @tab second col stuff
+% @tab Many paragraphs of text may be used in any column.
+%
+% They will wrap at the width determined by the template.
+% @item@tab@tab This will be in third column.
+% @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+% to baseline.
+% 0pt means it depends on current normal line spacing.

+% third args are \{left,right}hyphenmin.
+%
+% The language names to pass are determined when the format is built.
+% See the etex.log file created at that time, e.g.,
+% /usr/local/texlive/2008/texmf-var/web2c/pdftex/etex.log.
+%
+% With TeX Live 2008, etex now includes hyphenation patterns for all
+% available languages. This means we can support hyphenation in
+% Texinfo, at least to some extent. (This still doesn't solve the
+% accented characters problem.)

+
+# The arguments to this script should be names of files that contain
+# copyright statements to be updated. The copyright holder's name
+# defaults to "Free Software Foundation, Inc." but may be changed to
+# any other name by using the "UPDATE_COPYRIGHT_HOLDER" environment
+# variable.
+#
+# For example, you might wish to use the update-copyright target rule
+# in maint.mk from gnulib's maintainer-makefile module.
+#
+# Iff a copyright statement is recognized in a file and the final
+# year is not the current year, then the statement is updated for the
+# new year and it is reformatted to:
+#
+# 1. Fit within 72 columns.
+# 2. Convert 2-digit years to 4-digit years by prepending "19".
+# 3. Expand copyright year intervals. (See "Environment variables"
+# below.)
+#
+# A warning is printed for every file for which no copyright
+# statement is recognized.
+#
+# Each file's copyright statement must be formatted correctly in
+# order to be recognized. For example, each of these is fine:
+#
+# Copyright @copyright{} 1990-2005, 2007-2009 Free Software
+# Foundation, Inc.
+#
+# # Copyright (C) 1990-2005, 2007-2009 Free Software
+# # Foundation, Inc.
+#
+# /*
+# * Copyright © 90,2005,2007-2009
+# * Free Software Foundation, Inc.
+# */
+#
+# However, the following format is not recognized because the line
+# prefix changes after the first line:
+#
+# ## Copyright (C) 1990-2005, 2007-2009 Free Software
+# # Foundation, Inc.
+#
+# However, any correctly formatted copyright statement following
+# a non-matching copyright statements would be recognized.
+#
+# The exact conditions that a file's copyright statement must meet
+# to be recognized are:
+#
+# 1. It is the first copyright statement that meets all of the
+# following conditions. Subsequent copyright statements are
+# ignored.
+# 2. Its format is "Copyright (C)", then a list of copyright years,
+# and then the name of the copyright holder.
+# 3. The "(C)" takes one of the following forms or is omitted
+# entirely:
+#
+# A. (C)
+# B. (c)
+# C. @copyright{}
+# D. ©
+#
+# 4. The "Copyright" appears at the beginning of a line, except that it
+# may be prefixed by any sequence (e.g., a comment) of no more than
+# 5 characters -- including white space.
+# 5. Iff such a prefix is present, the same prefix appears at the
+# beginning of each remaining line within the FSF copyright
+# statement. There is one exception in order to support C-style
+# comments: if the first line's prefix contains nothing but
+# whitespace surrounding a "/*", then the prefix for all subsequent
+# lines is the same as the first line's prefix except with each of
+# "/" and possibly "*" replaced by a " ". The replacement of "*"
+# by " " is consistent throughout all subsequent lines.
+# 6. Blank lines, even if preceded by the prefix, do not appear
+# within the FSF copyright statement.
+# 7. Each copyright year is 2 or 4 digits, and years are separated by
+# commas or dashes. Whitespace may appear after commas.
+#
+# Environment variables:
+#
+# 1. If UPDATE_COPYRIGHT_FORCE=1, a recognized FSF copyright statement
+# is reformatted even if it does not need updating for the new
+# year. If unset or set to 0, only updated FSF copyright
+# statements are reformatted.
+# 2. If UPDATE_COPYRIGHT_USE_INTERVALS=1, every series of consecutive
+# copyright years (such as 90, 1991, 1992-2007, 2008) in a
+# reformatted FSF copyright statement is collapsed to a single
+# interval (such as 1990-2008). If unset or set to 0, all existing
+# copyright year intervals in a reformatted FSF copyright statement
+# are expanded instead.
+# If UPDATE_COPYRIGHT_USE_INTERVALS=2, convert a sequence with gaps
+# to the minimal containing range. For example, convert
+# 2000, 2004-2007, 2009 to 2000-2009.
+# 3. For testing purposes, you can set the assumed current year in
+# UPDATE_COPYRIGHT_YEAR.
+# 4. The default maximum line length for a copyright line is 72.
+# Set UPDATE_COPYRIGHT_MAX_LINE_LENGTH to use a different length.
+# 5. Set UPDATE_COPYRIGHT_HOLDER if the copyright holder is other
+# than "Free Software Foundation, Inc.".

+\`configure' configures GNU Bison 2.6 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CXX C++ compiler command
+ CXXFLAGS C++ compiler flags
+ CPP C preprocessor
+ YACC The `Yet Another Compiler Compiler' implementation to use.
+ Defaults to the first program found out of: `bison -y', `byacc',
+ `yacc'.
+ YFLAGS The list of arguments that will be passed by default to $YACC.
+ This script will default YFLAGS to the empty string to avoid a
+ default value of `-d' given by some make applications.
+ M4 Location of GNU M4 1.4.6 or later. Defaults to the first program
+ of `m4', `gm4', or `gnum4' on PATH that meets Autoconf needs.
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+This directory contains data needed by Bison.
+
+* Skeletons
+Bison skeletons: the general shapes of the different parser kinds,
+that are specialized for specific grammars by the bison program.
+
+Currently, the supported skeletons are:
+
+- yacc.c
+ It used to be named bison.simple: it corresponds to C Yacc
+ compatible LALR(1) parsers.
+
+- lalr1.cc
+ Produces a C++ parser class.
+
+- lalr1.java
+ Produces a Java parser class.
+
+- glr.c
+ A Generalized LR C parser based on Bison's LALR(1) tables.
+
+- glr.cc
+ A Generalized LR C++ parser. Actually a C++ wrapper around glr.c.
+
+These skeletons are the only ones supported by the Bison team.
+Because the interface between skeletons and the bison program is not
+finished, *we are not bound to it*. In particular, Bison is not
+mature enough for us to consider that ``foreign skeletons'' are
+supported.
+
+* m4sugar
+This directory contains M4sugar, sort of an extended library for M4,
+which is used by Bison to instantiate the skeletons.
+
+* xslt
+This directory contains XSLT programs that transform Bison's XML output
+into various formats.
+
+- bison.xsl
+ A library of routines used by the other XSLT programs.
+
+- xml2dot.xsl
+ Conversion into GraphViz's dot format.
+
+- xml2text.xsl
+ Conversion into text.
+
+- xml2xhtml.xsl
+ Conversion into XHTML.

+# mangled. Thus, they print to stdout directly.
+
+# b4_cat(TEXT)
+# ------------

+# b4_cat([[@complain(invalid input@)]])

+# ----------------------------------------------------------

+# b4_warn()
+# b4_warn(1)
+# b4_warn(1, 2)
+#
+# Should produce this without newlines:
+#
+# @warn([asdf), asdf]@,[fsa), fsa]@,[fdsa), fdsa]@)
+# @warn(asdf), asdf@,fsa), fsa@,fdsa), fdsa@)

+# This skeleton produces a C++ class that encapsulates a C glr parser.
+# This is in order to reduce the maintenance burden. The glr.c
+# skeleton is clean and pure enough so that there are no real
+# problems. The C++ interface is the same as that of lalr1.cc. In
+# fact, glr.c can replace yacc.c without the user noticing any
+# difference, and similarly for glr.cc replacing lalr1.cc.
+#
+# The passing of parse-params
+#
+# The additional arguments are stored as members of the parser
+# object, yyparser. The C routines need to carry yyparser
+# throughout the C parser; that easy: just let yyparser become an
+# additional parse-param. But because the C++ skeleton needs to
+# know the "real" original parse-param, we save them
+# (b4_parse_param_orig). Note that b4_parse_param is overquoted
+# (and c.m4 strips one level of quotes). This is a PITA, and
+# explains why there are so many levels of quotes.
+#
+# The locations
+#
+# We use location.cc just like lalr1.cc, but because glr.c stores
+# the locations in a (C++) union, the position and location classes
+# must not have a constructor. Therefore, contrary to lalr1.cc, we
+# must not define "b4_location_constructors". As a consequence the
+# user must initialize the first positions (in particular the
+# filename member).

+ - If this state is a consistent state with a default action,

+ - The only way there can be no lookahead present (in tok) is
+ if this state is a consistent state with a default action.
+ Thus, detecting the absence of a lookahead is sufficient to
+ determine that there is no unexpected or expected token to
+ report. In that case, just report a simple "syntax error".
+ - Don't assume there isn't a lookahead just because this
+ state is a consistent state with a default action. There
+ might have been a previous inconsistent state, consistent
+ state with a non-default action, or user semantic action
+ that manipulated yychar. (However, yychar is currently out
+ of scope during semantic actions.)
+ - Of course, the expected token list depends on states to
+ have correct lookahead information, and it depends on the
+ parser not to perform extra reductions after fetching a
+ lookahead from the scanner and before detecting a syntax
+ error. Thus, state merging (from LALR or IELR) and default
+ reductions corrupt the expected token list. However, the
+ list is correct for canonical LR with one exception: it
+ will still contain any token that will not be accepted due
+ to an error action in a later state.

+
+# In M4 1.4.x, every byte of $@ is rescanned. This means that an
+# algorithm on n arguments that recurses with one less argument each
+# iteration will scan n * (n + 1) / 2 arguments, for O(n^2) time. In
+# M4 1.6, this was fixed so that $@ is only scanned once, then
+# back-references are made to information stored about the scan.
+# Thus, n iterations need only scan n arguments, for O(n) time.
+# Additionally, in M4 1.4.x, recursive algorithms did not clean up
+# memory very well, requiring O(n^2) memory rather than O(n) for n
+# iterations.
+#
+# This file is designed to overcome the quadratic nature of $@
+# recursion by writing a variant of m4_foreach that uses m4_for rather
+# than $@ recursion to operate on the list. This involves more macro
+# expansions, but avoids the need to rescan a quadratic number of
+# arguments, making these replacements very attractive for M4 1.4.x.
+# On the other hand, in any version of M4, expanding additional macros
+# costs additional time; therefore, in M4 1.6, where $@ recursion uses
+# fewer macros, these replacements actually pessimize performance.
+# Additionally, the use of $10 to mean the tenth argument violates
+# POSIX; although all versions of m4 1.4.x support this meaning, a
+# future m4 version may switch to take it as the first argument
+# concatenated with a literal 0, so the implementations in this file
+# are not future-proof. Thus, this file is conditionally included as
+# part of m4_init(), only when it is detected that M4 probably has
+# quadratic behavior (ie. it lacks the macro __m4_version__).
+#
+# Please keep this file in sync with m4sugar.m4.
+
+# _m4_foreach(PRE, POST, IGNORED, ARG...)
+# ---------------------------------------
+# Form the common basis of the m4_foreach and m4_map macros. For each
+# ARG, expand PRE[ARG]POST[]. The IGNORED argument makes recursion
+# easier, and must be supplied rather than implicit.
+#
+# This version minimizes the number of times that $@ is evaluated by
+# using m4_for to generate a boilerplate into _m4_f then passing $@ to
+# that temporary macro. Thus, the recursion is done in m4_for without
+# reparsing any user input, and is not quadratic. For an idea of how
+# this works, note that m4_foreach(i,[1,2],[i]) calls
+# _m4_foreach([m4_define([i],],[)i],[],[1],[2])
+# which defines _m4_f:
+# $1[$4]$2[]$1[$5]$2[]_m4_popdef([_m4_f])
+# then calls _m4_f([m4_define([i],],[)i],[],[1],[2]) for a net result:

+# With a better look, you realize that the parens are more a pain than

+# But wait - now the algorithm is quadratic, because every recursion of

+## 10. Defining macros with bells and whistles. ##
+## --------------------------------------------- ##
+
+# `m4_defun' is basically `m4_define' but it equips the macro with the
+# needed machinery for `m4_require'. A macro must be m4_defun'd if
+# either it is m4_require'd, or it m4_require's.
+#
+# Two things deserve attention and are detailed below:
+# 1. Implementation of m4_require
+# 2. Keeping track of the expansion stack
+#
+# 1. Implementation of m4_require
+# ===============================
+#
+# Of course m4_defun calls m4_provide, so that a macro which has
+# been expanded is not expanded again when m4_require'd, but the
+# difficult part is the proper expansion of macros when they are
+# m4_require'd.
+#
+# The implementation is based on three ideas, (i) using diversions to
+# prepare the expansion of the macro and its dependencies (by Franc,ois
+# Pinard), (ii) expand the most recently m4_require'd macros _after_
+# the previous macros (by Axel Thimm), and (iii) track instances of
+# provide before require (by Eric Blake).
+#
+#
+# The first idea: why use diversions?
+# -----------------------------------
+#
+# When a macro requires another, the other macro is expanded in new
+# diversion, GROW. When the outer macro is fully expanded, we first
+# undivert the most nested diversions (GROW - 1...), and finally
+# undivert GROW. To understand why we need several diversions,
+# consider the following example:
+#
+# | m4_defun([TEST1], [Test...m4_require([TEST2])1])
+# | m4_defun([TEST2], [Test...m4_require([TEST3])2])
+# | m4_defun([TEST3], [Test...3])
+#
+# Because m4_require is not required to be first in the outer macros, we
+# must keep the expansions of the various levels of m4_require separated.
+# Right before executing the epilogue of TEST1, we have:
+#
+# GROW - 2: Test...3
+# GROW - 1: Test...2
+# GROW: Test...1
+# BODY:
+#
+# Finally the epilogue of TEST1 undiverts GROW - 2, GROW - 1, and
+# GROW into the regular flow, BODY.
+#
+# GROW - 2:
+# GROW - 1:
+# GROW:
+# BODY: Test...3; Test...2; Test...1
+#
+# (The semicolons are here for clarification, but of course are not
+# emitted.) This is what Autoconf 2.0 (I think) to 2.13 (I'm sure)
+# implement.
+#
+#
+# The second idea: first required first out
+# -----------------------------------------
+#
+# The natural implementation of the idea above is buggy and produces
+# very surprising results in some situations. Let's consider the
+# following example to explain the bug:
+#
+# | m4_defun([TEST1], [m4_require([TEST2a])m4_require([TEST2b])])
+# | m4_defun([TEST2a], [])
+# | m4_defun([TEST2b], [m4_require([TEST3])])
+# | m4_defun([TEST3], [m4_require([TEST2a])])
+# |
+# | AC_INIT
+# | TEST1
+#
+# The dependencies between the macros are:
+#
+# 3 --- 2b
+# / \ is m4_require'd by
+# / \ left -------------------- right
+# 2a ------------ 1
+#
+# If you strictly apply the rules given in the previous section you get:
+#
+# GROW - 2: TEST3
+# GROW - 1: TEST2a; TEST2b
+# GROW: TEST1
+# BODY:
+#
+# (TEST2a, although required by TEST3 is not expanded in GROW - 3
+# because is has already been expanded before in GROW - 1, so it has
+# been AC_PROVIDE'd, so it is not expanded again) so when you undivert
+# the stack of diversions, you get:
+#
+# GROW - 2:
+# GROW - 1:
+# GROW:
+# BODY: TEST3; TEST2a; TEST2b; TEST1
+#
+# i.e., TEST2a is expanded after TEST3 although the latter required the
+# former.
+#
+# Starting from 2.50, we use an implementation provided by Axel Thimm.
+# The idea is simple: the order in which macros are emitted must be the
+# same as the one in which macros are expanded. (The bug above can
+# indeed be described as: a macro has been m4_provide'd before its
+# dependent, but it is emitted after: the lack of correlation between
+# emission and expansion order is guilty).
+#
+# How to do that? You keep the stack of diversions to elaborate the
+# macros, but each time a macro is fully expanded, emit it immediately.
+#
+# In the example above, when TEST2a is expanded, but it's epilogue is
+# not run yet, you have:
+#
+# GROW - 2:
+# GROW - 1: TEST2a
+# GROW: Elaboration of TEST1
+# BODY:
+#
+# The epilogue of TEST2a emits it immediately:
+#
+# GROW - 2:
+# GROW - 1:
+# GROW: Elaboration of TEST1
+# BODY: TEST2a
+#
+# TEST2b then requires TEST3, so right before the epilogue of TEST3, you
+# have:
+#
+# GROW - 2: TEST3
+# GROW - 1: Elaboration of TEST2b
+# GROW: Elaboration of TEST1
+# BODY: TEST2a
+#
+# The epilogue of TEST3 emits it:
+#
+# GROW - 2:
+# GROW - 1: Elaboration of TEST2b
+# GROW: Elaboration of TEST1
+# BODY: TEST2a; TEST3
+#
+# TEST2b is now completely expanded, and emitted:
+#
+# GROW - 2:
+# GROW - 1:
+# GROW: Elaboration of TEST1
+# BODY: TEST2a; TEST3; TEST2b
+#
+# and finally, TEST1 is finished and emitted:
+#
+# GROW - 2:
+# GROW - 1:
+# GROW:
+# BODY: TEST2a; TEST3; TEST2b: TEST1
+#
+# The idea is simple, but the implementation is a bit involved. If
+# you are like me, you will want to see the actual functioning of this
+# implementation to be convinced. The next section gives the full
+# details.
+#
+#
+# The Axel Thimm implementation at work
+# -------------------------------------
+#
+# We consider the macros above, and this configure.ac:
+#
+# AC_INIT
+# TEST1
+#
+# You should keep the definitions of _m4_defun_pro, _m4_defun_epi, and
+# m4_require at hand to follow the steps.
+#
+# This implementation tries not to assume that the current diversion is
+# BODY, so as soon as a macro (m4_defun'd) is expanded, we first
+# record the current diversion under the name _m4_divert_dump (denoted
+# DUMP below for short). This introduces an important difference with
+# the previous versions of Autoconf: you cannot use m4_require if you
+# are not inside an m4_defun'd macro, and especially, you cannot
+# m4_require directly from the top level.
+#
+# We have not tried to simulate the old behavior (better yet, we
+# diagnose it), because it is too dangerous: a macro m4_require'd from
+# the top level is expanded before the body of `configure', i.e., before
+# any other test was run. I let you imagine the result of requiring
+# AC_STDC_HEADERS for instance, before AC_PROG_CC was actually run....
+#
+# After AC_INIT was run, the current diversion is BODY.
+# * AC_INIT was run
+# DUMP: undefined
+# diversion stack: BODY |-
+#
+# * TEST1 is expanded
+# The prologue of TEST1 sets _m4_divert_dump, which is the diversion
+# where the current elaboration will be dumped, to the current
+# diversion. It also m4_divert_push to GROW, where the full
+# expansion of TEST1 and its dependencies will be elaborated.
+# DUMP: BODY
+# BODY: empty
+# diversions: GROW, BODY |-
+#
+# * TEST1 requires TEST2a
+# _m4_require_call m4_divert_pushes another temporary diversion,
+# GROW - 1, and expands TEST2a in there.
+# DUMP: BODY
+# BODY: empty
+# GROW - 1: TEST2a
+# diversions: GROW - 1, GROW, BODY |-
+# Then the content of the temporary diversion is moved to DUMP and the
+# temporary diversion is popped.
+# DUMP: BODY
+# BODY: TEST2a

+#
+# * TEST1 requires TEST2b

+# diversions: GROW - 2, GROW - 1, GROW, BODY |-
+# Then the diversion is appended to DUMP, and popped.

+# BODY: TEST2a; TEST3

+#
+# * TEST1 requires TEST2b (contd.)

+#
+# The third idea: track macros provided before they were required
+# ---------------------------------------------------------------
+#
+# Using just the first two ideas, Autoconf 2.50 through 2.63 still had
+# a subtle bug for more than seven years. Let's consider the
+# following example to explain the bug:
+#
+# | m4_defun([TEST1], [1])

+# | TEST3
+#
+# After the prologue of TEST3, we are collecting text in GROW with the
+# intent of dumping it in BODY during the epilogue. Next, we
+# encounter the direct invocation of TEST1, which provides the macro
+# in place in GROW. From there, we encounter a requirement for TEST2,
+# which must be collected in a new diversion. While expanding TEST2,
+# we encounter a requirement for TEST1, but since it has already been
+# expanded, the Axel Thimm algorithm states that we can treat it as a
+# no-op. But that would lead to an end result of `2 3 1', meaning
+# that we have once again output a macro (TEST2) prior to its
+# requirements (TEST1).
+#
+# The problem can only occur if a single defun'd macro first provides,
+# then later indirectly requires, the same macro. Note that directly
+# expanding then requiring a macro is okay: because the dependency was
+# met, the require phase can be a no-op. For that matter, the outer
+# macro can even require two helpers, where the first helper expands
+# the macro, and the second helper indirectly requires the macro.
+# Out-of-order expansion is only present if the inner macro is
+# required by something that will be hoisted in front of where the
+# direct expansion occurred. In other words, we must be careful not
+# to warn on:
+#
+# | m4_defun([TEST4], [4])
+# | m4_defun([TEST5], [5 TEST4 m4_require([TEST4])])
+# | TEST5 => 5 4
+#
+# or even the more complex:
+#
+# | m4_defun([TEST6], [6])
+# | m4_defun([TEST7], [7 TEST6])
+# | m4_defun([TEST8], [8 m4_require([TEST6])])
+# | m4_defun([TEST9], [9 m4_require([TEST8])])
+# | m4_defun([TEST10], [10 m4_require([TEST7]) m4_require([TEST9])])
+# | TEST10 => 7 6 8 9 10
+#
+# So, to detect whether a require was direct or indirect, m4_defun and
+# m4_require track the name of the macro that caused a diversion to be
+# created (using the stack _m4_diverting, coupled with an O(1) lookup
+# _m4_diverting([NAME])), and m4_provide stores the name associated
+# with the diversion at which a macro was provided. A require call is
+# direct if it occurs within the same diversion where the macro was
+# provided, or if the diversion associated with the providing context
+# has been collected.
+#
+# The implementation of the warning involves tracking the set of
+# macros which have been provided since the start of the outermost
+# defun'd macro (the set is named _m4_provide). When starting an
+# outermost macro, the set is emptied; when a macro is provided, it is
+# added to the set; when require expands the body of a macro, it is
+# removed from the set; and when a macro is indirectly required, the
+# set is checked. If a macro is in the set, then it has been provided
+# before it was required, and we satisfy dependencies by expanding the
+# macro as if it had never been provided; in the example given above,
+# this means we now output `1 2 3 1'. Meanwhile, a warning is issued
+# to inform the user that her macros trigger the bug in older autoconf
+# versions, and that her output file now contains redundant contents
+# (and possibly new problems, if the repeated macro was not
+# idempotent). Meanwhile, macros defined by m4_defun_once instead of
+# m4_defun are idempotent, avoiding any warning or duplicate output.
+#
+#
+# 2. Keeping track of the expansion stack
+# =======================================
+#
+# When M4 expansion goes wrong it is often extremely hard to find the
+# path amongst macros that drove to the failure. What is needed is
+# the stack of macro `calls'. One could imagine that GNU M4 would
+# maintain a stack of macro expansions, unfortunately it doesn't, so
+# we do it by hand. This is of course extremely costly, but the help
+# this stack provides is worth it. Nevertheless to limit the
+# performance penalty this is implemented only for m4_defun'd macros,
+# not for define'd macros.
+#
+# Each time we enter an m4_defun'd macros, we add a definition in
+# _m4_expansion_stack, and when we exit the macro, we remove it (thanks
+# to pushdef/popdef). m4_stack_foreach is used to print the expansion
+# stack in the rare cases when it's needed.
+#
+# In addition, we want to detect circular m4_require dependencies.
+# Each time we expand a macro FOO we define _m4_expanding(FOO); and
+# m4_require(BAR) simply checks whether _m4_expanding(BAR) is defined.
+
+
+# m4_expansion_stack
+# ------------------
+# Expands to the entire contents of the expansion stack. The caller
+# must supply a trailing newline. This macro always prints a
+# location; check whether _m4_expansion_stack is defined to filter out
+# the case when no defun'd macro is in force.

+## 15. Set handling. ##
+## ------------------ ##
+
+# Autoconf likes to create arbitrarily large sets; for example, as of
+# this writing, the configure.ac for coreutils tracks a set of more
+# than 400 AC_SUBST. How do we track all of these set members,
+# without introducing duplicates? We could use m4_append_uniq, with
+# the set NAME residing in the contents of the macro NAME.
+# Unfortunately, m4_append_uniq is quadratic for set creation, because
+# it costs O(n) to search the string for each of O(n) insertions; not
+# to mention that with m4 1.4.x, even using m4_append is slow, costing
+# O(n) rather than O(1) per insertion. Other set operations, not used
+# by Autoconf but still possible by manipulation of the definition
+# tracked in macro NAME, include O(n) deletion of one element and O(n)
+# computation of set size. Because the set is exposed to the user via
+# the definition of a single macro, we cannot cache any data about the
+# set without risking the cache being invalidated by the user
+# redefining NAME.
+#
+# Can we do better? Yes, because m4 gives us an O(1) search function
+# for free: ifdef. Additionally, even m4 1.4.x gives us an O(1)
+# insert operation for free: pushdef. But to use these, we must
+# represent the set via a group of macros; to keep the set consistent,
+# we must hide the set so that the user can only manipulate it through
+# accessor macros. The contents of the set are maintained through two
+# access points; _m4_set([name]) is a pushdef stack of values in the
+# set, useful for O(n) traversal of the set contents; while the
+# existence of _m4_set([name],value) with no particular value is
+# useful for O(1) querying of set membership. And since the user
+# cannot externally manipulate the set, we are free to add additional
+# caching macros for other performance improvements. Deletion can be
+# O(1) per element rather than O(n), by reworking the definition of
+# _m4_set([name],value) to be 0 or 1 based on current membership, and
+# adding _m4_set_cleanup(name) to defer the O(n) cleanup of
+# _m4_set([name]) until we have another reason to do an O(n)
+# traversal. The existence of _m4_set_cleanup(name) can then be used
+# elsewhere to determine if we must dereference _m4_set([name],value),
+# or assume that definition implies set membership. Finally, size can
+# be tracked in an O(1) fashion with _m4_set_size(name).
+#
+# The quoting in _m4_set([name],value) is chosen so that there is no
+# ambiguity with a set whose name contains a comma, and so that we can
+# supply the value via _m4_defn([_m4_set([name])]) without needing any

+
+
+1.: DJGPP specific changes.
+ =======================
+
+ The DJGPP port of Bison offers LFN and SFN support depending on which
+ OS it is running. If LFN support is available or not is determinated at
+ run time. If LFN support is available (DOS session under Win9X, Win2K,
+ WinXP, etc.) the standard posix file name extensions will be used.
+ These are: y.tab.c, y.tab.c++, y.tab.h, y.output, etc. If only SFN
+ support is available (plain DOS), then the standard MSDOS short file
+ names will be used. These are: y_tab.c, y_tab.h, y.out, etc.
+ It should be noticed that this bison version needs the m4 program as
+ back end to generate the parser file (y.tab.c etc.) from the skeleton
+ files. This implies that m4 must always be installed to get bison
+ working. m4 will use a couple of m4 scripts that will be installed in
+ /dev/env/DJDIR/share/bison and shall not be removed.
+ It should also be noticed that the skeleton files bison.simple and
+ bison.hairy are no longer supported. This applies also to the environ-
+ ment variables BISON_HAIRY and BISON_SIMPLE. Those variables are *no*
+ longer honored at all.
+ The kind of skeleton file bison.hairy is no longer supported at all.
+ The skeleton file bison.simple is now called yacc.c and is an m4 script.
+ The other two skeleton files supported by this bison version are glr.c
+ and lalr1.cc. The first one is a generalized LR C parser based on
+ Bison's LALR(1) tables and the second one is a experimental C++ parser
+ class.
+ As has been told before, bison uses m4 to generate the parser file.
+ This is done by forking and using pipes for the IPC. MSDOS does not
+ support this functionality so this has been reproduced in the usual
+ way by redirecting stdin and stdout of bison and m4 to temporary files
+ and processing these files in sequence.
+ It should be noticed that due to the great amount of file names that do
+ not cleanly map to 8.3 file names, you will need an OS with LFN support
+ to configure and compile the sources. On Win98 this implies that the
+ generation of numeric tails for 8.3 file name aliases must be enabled
+ or the compilation will fail.
+
+
+ Please **read** the docs.
+
+
+2.: Installing the binary package.
+ ==============================
+
+2.1.: Copy the binary distribution into the top DJGPP installation directory,
+ just unzip it preserving the directory structure running *ONE* of the
+ following commands:
+ unzip32 bsn@PACKAGE_VERSION@b.zip or
+ djtarx bsn@PACKAGE_VERSION@b.zip or
+ pkunzip -d bsn@PACKAGE_VERSION@b.zip
+
+
+
+3.: Building the binaries from sources.
+ ===================================
+
+3.1.: Create a temporary directory and copy the source package into the
+ directory. If you download the source distribution from one of the
+ DJGPP sites, just unzip it preserving the directory structure
+ running *ONE* of the following commands:
+ unzip32 bsn@PACKAGE_VERSION@s.zip or
+ djtarx bsn@PACKAGE_VERSION@s.zip or
+ pkunzip -d bsn@PACKAGE_VERSION@s.zip
+ and proceed to the paragraph 3.3, below.
+
+3.2.: Source distributions downloaded from one of the GNU FTP sites need
+ some more work to unpack, if LFN support is not available. If LFN is
+ available then you can extract the source files from the archive with
+ any unzip program and proceed to the paragraph 3.3, below. Any file
+ name issue will be handled by the DJGPP configuration files.
+ To unpack the source distribution on SFN systems, first, you MUST use
+ the `djunpack' batch file to unzip the package. That is because some
+ file names in the official distributions need to be changed to avoid
+ problems on the various platforms supported by DJGPP.
+ `djunpack' invokes the `djtar' program (that is part of the basic DJGPP
+ development kit) to rename these files on the fly given a file with
+ name mappings; the distribution includes a file `djgpp/fnchange.lst'
+ with the necessary mappings. So you need first to retrieve that batch
+ file, and then invoke it to unpack the distribution. Here's how:
+
+ djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar.gz > djunpack.bat
+ djunpack bison-@VERSION@.tar.gz
+
+ (The name of the distribution archive and the leading directory of the
+ path to `djunpack.bat' in the distribution will be different for
+ versions of Bison other than @VERSION@.)
+
+ If the argument to `djunpack.bat' include leading directories, it MUST
+ be given with the DOS-style backslashes; Unix-style forward slashes
+ will NOT work.
+
+ If the distribution comes as a .tar.bz2 archive, and your version of
+ `djtar' doesn't support bzip2 decompression, you need to unpack it as
+ follows:
+
+ bnzip2 bison-@VERSION@.tar.bz2
+ djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar > djunpack.bat
+ djunpack bison-@VERSION@.tar
+
+3.3.: To build the binaries you will need the following binary packages:
+ djdev203.zip (or a later but NOT a prior version)
+ bsh204b.zip (or a later but NOT a prior version)
+ gccNNNb.zip, gppNNN.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip,
+ perlNNNb.zip, shlNNNb.zip, txtNNNb.zip, txiNNNb.zip, grepNNNb.zip,
+ sedNNNb.zip and m4NNN.zip
+
+ If you want to run the check you will need also:
+ difNNNb.zip
+
+ NNN represents the latest version number of the binary packages. All
+ this packages can be found in the /v2gnu directory of any
+ ftp.delorie.com mirror.
+ You will need bsh204b.zip or later and *NOT* a prior version or
+ the build will fail. The same applies to djdev203.zip. Please note
+ that Bison requires m4-144b.zip or later to work properly.
+
+3.4.: If for some reason you want to reconfigure the package cd into the top
+ srcdir (bison-@TREE_VERSION@) and run the following commands:
+ del djgpp\config.cache
+ make clean
+ djgpp\config
+
+ Please note that you *MUST* delete the config.cache file in the djgpp
+ subdir or you will not really reconfigure the sources because the
+ configuration informations will be read from the cache file instead
+ of being newly computed.
+ To build the programs in a directory other than where the sources are,
+ you must add the parameter that specifies the source directory,
+ e.g:
+ x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
+
+ Lets assume you want to build the binaries in a directory placed on a
+ different drive (z:\build in this case) from where the sources are,
+ then you will run the following commands:
+ z:
+ md \build
+ cd \build
+ x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
+
+ The order of the options and the srcdir option does not matter. You
+ *MUST* use forward slashes to specify the source directory.
+
+ The batch file will set same environment variables, make MSDOS specific
+ modifications to the Makefile.in's and supply all other needed options
+ to the configure script.
+
+3.5.: To compile the package run from the top srcdir the command:
+ make
+
+3.6.: Now you can run the tests if you like. From the top srcdir run the
+ command:
+ make check
+
+ No test should fail but the tests #131 (Doxygen Public Documentation)
+ and #132 (Doxygen Private Documentation) will be skipped. Please note
+ that the testsuite only works with LFN available. On plain DOS, most
+ of the tests will fail due to invalid DOS names.
+
+3.7.: To install the binaries, header, library, catalogs, and info docs
+ run the following command from the top srcdir:
+ make install
+
+ This will install the products into your DJGPP installation tree given
+ by the default prefix "/dev/env/DJDIR". If you prefer to install them
+ into some other directory you will have to set prefix to the appropriate
+ value:
+ make install prefix=z:/some/other/place
+
+
+
+ Send GNU bison specific bug reports to <bug-bison@gnu.org>.
+ Send suggestions and bug reports concerning the DJGPP port to
+ comp.os.msdos.djgpp or <djgpp@delorie.com>.
+
+
+Enjoy.

+.SH NAME
+bison \- GNU Project parser generator (yacc replacement)
+.SH SYNOPSIS
+.B bison
+[\fIOPTION\fR]... \fIFILE\fR
+.SH DESCRIPTION
+.I Bison
+is a parser generator in the style of
+.IR yacc (1).
+It should be upwardly compatible with input files designed
+for
+.IR yacc .
+.PP
+Input files should follow the
+.I yacc
+convention of ending in
+.BR .y .
+Unlike
+.IR yacc ,
+the generated files do not have fixed names, but instead use the prefix
+of the input file.
+Moreover, if you need to put
+.I C++
+code in the input file, you can end his name by a C++-like extension
+(.ypp or .y++), then bison will follow your extension to name the
+output file (.cpp or .c++).
+For instance, a grammar description file named
+.B parse.yxx
+would produce the generated parser in a file named
+.BR parse.tab.cxx ,
+instead of
+.IR yacc 's
+.B y.tab.c
+or old
+.I Bison
+version's
+.BR parse.tab.c .
+.PP
+This description of the options that can be given to
+.I bison
+is adapted from the node
+.B Invocation
+in the
+.B bison.texinfo
+manual, which should be taken as authoritative.
+.PP
+.I Bison
+supports both traditional single-letter options and mnemonic long
+option names. Long option names are indicated with
+.B \-\-
+instead of
+.BR \- .
+Abbreviations for option names are allowed as long as they
+are unique. When a long option takes an argument, like
+.BR \-\-file-prefix ,
+connect the option name and the argument with
+.BR = .
+.PP
+Generate a deterministic LR or generalized LR (GLR) parser employing
+LALR(1), IELR(1), or canonical LR(1) parser tables. IELR(1) and
+canonical LR(1) support is experimental.
+.PP
+Mandatory arguments to long options are mandatory for short options too.
+The same is true for optional arguments.

+Introduction
+************
+
+"Bison" is a general-purpose parser generator that converts an
+annotated context-free grammar into a deterministic LR or generalized
+LR (GLR) parser employing LALR(1) parser tables. As an experimental
+feature, Bison can also generate IELR(1) or canonical LR(1) parser
+tables. Once you are proficient with Bison, you can use it to develop
+a wide range of language parsers, from those used in simple desk
+calculators to complex programming languages.
+
+ Bison is upward compatible with Yacc: all properly-written Yacc
+grammars ought to work with Bison with no change. Anyone familiar with
+Yacc should be able to use Bison with little trouble. You need to be
+fluent in C or C++ programming in order to use Bison or to understand
+this manual. Java is also supported as an experimental feature.
+
+ We begin with tutorial chapters that explain the basic concepts of
+using Bison and show three explained examples, each building on the
+last. If you don't know Bison or Yacc, start by reading these
+chapters. Reference chapters follow, which describe specific aspects
+of Bison in detail.
+
+ Bison was written originally by Robert Corbett. Richard Stallman
+made it Yacc-compatible. Wilfred Hansen of Carnegie Mellon University
+added multi-character string literals and other features. Since then,
+Bison has grown more robust and evolved many other new features thanks
+to the hard work of a long list of volunteers. For details, see the
+`THANKS' and `ChangeLog' files included in the Bison distribution.
+
+ This edition corresponds to version 2.6 of Bison.

+
+Conditions for Using Bison
+**************************
+
+The distribution terms for Bison-generated parsers permit using the
+parsers in nonfree programs. Before Bison version 2.2, these extra
+permissions applied only when Bison was generating LALR(1) parsers in
+C. And before Bison version 1.24, Bison-generated parsers could be
+used only in programs that were free software.
+
+ The other GNU programming tools, such as the GNU C compiler, have
+never had such a requirement. They could always be used for nonfree
+software. The reason Bison was different was not due to a special
+policy decision; it resulted from applying the usual General Public
+License to all of the Bison source code.
+
+ The main output of the Bison utility--the Bison parser implementation
+file--contains a verbatim copy of a sizable piece of Bison, which is
+the code for the parser's implementation. (The actions from your
+grammar are inserted into this implementation at one point, but most of
+the rest of the implementation is not changed.) When we applied the
+GPL terms to the skeleton code for the parser's implementation, the
+effect was to restrict the use of Bison output to free software.
+
+ We didn't change the terms because of sympathy for people who want to
+make software proprietary. *Software should be free.* But we
+concluded that limiting Bison's use to free software was doing little to
+encourage people to make other software free. So we decided to make the
+practical conditions for using Bison match the practical conditions for
+using the other GNU tools.
+
+ This exception applies when Bison is generating code for a parser.
+You can tell whether the exception applies to a Bison output file by
+inspecting the file for text beginning with "As a special
+exception...". The text spells out the exact terms of the exception.

+GNU GENERAL PUBLIC LICENSE
+**************************
+
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. `http://fsf.org/'
+
+ Everyone is permitted to copy and distribute verbatim copies of this
+ license document, but changing it is not allowed.
+
+Preamble
+========
+
+The GNU General Public License is a free, copyleft license for software
+and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains
+free software for all its users. We, the Free Software Foundation, use
+the GNU General Public License for most of our software; it applies
+also to any other work released this way by its authors. You can apply
+it to your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you
+have certain responsibilities if you distribute copies of the software,
+or if you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the
+manufacturer can do so. This is fundamentally incompatible with the
+aim of protecting users' freedom to change the software. The
+systematic pattern of such abuse occurs in the area of products for
+individuals to use, which is precisely where it is most unacceptable.
+Therefore, we have designed this version of the GPL to prohibit the
+practice for those products. If such problems arise substantially in
+other domains, we stand ready to extend this provision to those domains
+in future versions of the GPL, as needed to protect the freedom of
+users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+TERMS AND CONDITIONS
+====================
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public
+ License.
+
+ "Copyright" also means copyright-like laws that apply to other
+ kinds of works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+ License. Each licensee is addressed as "you". "Licensees" and
+ "recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the
+ work in a fashion requiring copyright permission, other than the
+ making of an exact copy. The resulting work is called a "modified
+ version" of the earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work
+ based on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+ permission, would make you directly or secondarily liable for
+ infringement under applicable copyright law, except executing it
+ on a computer or modifying a private copy. Propagation includes
+ copying, distribution (with or without modification), making
+ available to the public, and in some countries other activities as
+ well.
+
+ To "convey" a work means any kind of propagation that enables other
+ parties to make or receive copies. Mere interaction with a user
+ through a computer network, with no transfer of a copy, is not
+ conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+ to the extent that it includes a convenient and prominently visible
+ feature that (1) displays an appropriate copyright notice, and (2)
+ tells the user that there is no warranty for the work (except to
+ the extent that warranties are provided), that licensees may
+ convey the work under this License, and how to view a copy of this
+ License. If the interface presents a list of user commands or
+ options, such as a menu, a prominent item in the list meets this
+ criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+ for making modifications to it. "Object code" means any
+ non-source form of a work.
+
+ A "Standard Interface" means an interface that either is an
+ official standard defined by a recognized standards body, or, in
+ the case of interfaces specified for a particular programming
+ language, one that is widely used among developers working in that
+ language.
+
+ The "System Libraries" of an executable work include anything,
+ other than the work as a whole, that (a) is included in the normal
+ form of packaging a Major Component, but which is not part of that
+ Major Component, and (b) serves only to enable use of the work
+ with that Major Component, or to implement a Standard Interface
+ for which an implementation is available to the public in source
+ code form. A "Major Component", in this context, means a major
+ essential component (kernel, window system, and so on) of the
+ specific operating system (if any) on which the executable work
+ runs, or a compiler used to produce the work, or an object code
+ interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+ the source code needed to generate, install, and (for an executable
+ work) run the object code and to modify the work, including
+ scripts to control those activities. However, it does not include
+ the work's System Libraries, or general-purpose tools or generally
+ available free programs which are used unmodified in performing
+ those activities but which are not part of the work. For example,
+ Corresponding Source includes interface definition files
+ associated with source files for the work, and the source code for
+ shared libraries and dynamically linked subprograms that the work
+ is specifically designed to require, such as by intimate data
+ communication or control flow between those subprograms and other
+ parts of the work.
+
+ The Corresponding Source need not include anything that users can
+ regenerate automatically from other parts of the Corresponding
+ Source.
+
+ The Corresponding Source for a work in source code form is that
+ same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+ copyright on the Program, and are irrevocable provided the stated
+ conditions are met. This License explicitly affirms your unlimited
+ permission to run the unmodified Program. The output from running
+ a covered work is covered by this License only if the output,
+ given its content, constitutes a covered work. This License
+ acknowledges your rights of fair use or other equivalent, as
+ provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+ convey, without conditions so long as your license otherwise
+ remains in force. You may convey covered works to others for the
+ sole purpose of having them make modifications exclusively for
+ you, or provide you with facilities for running those works,
+ provided that you comply with the terms of this License in
+ conveying all material for which you do not control copyright.
+ Those thus making or running the covered works for you must do so
+ exclusively on your behalf, under your direction and control, on
+ terms that prohibit them from making any copies of your
+ copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+ the conditions stated below. Sublicensing is not allowed; section
+ 10 makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+ measure under any applicable law fulfilling obligations under
+ article 11 of the WIPO copyright treaty adopted on 20 December
+ 1996, or similar laws prohibiting or restricting circumvention of
+ such measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+ circumvention of technological measures to the extent such
+ circumvention is effected by exercising rights under this License
+ with respect to the covered work, and you disclaim any intention
+ to limit operation or modification of the work as a means of
+ enforcing, against the work's users, your or third parties' legal
+ rights to forbid circumvention of technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+ receive it, in any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright notice;
+ keep intact all notices stating that this License and any
+ non-permissive terms added in accord with section 7 apply to the
+ code; keep intact all notices of the absence of any warranty; and
+ give all recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+ and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+ produce it from the Program, in the form of source code under the
+ terms of section 4, provided that you also meet all of these
+ conditions:
+
+ a. The work must carry prominent notices stating that you
+ modified it, and giving a relevant date.
+
+ b. The work must carry prominent notices stating that it is
+ released under this License and any conditions added under
+ section 7. This requirement modifies the requirement in
+ section 4 to "keep intact all notices".
+
+ c. You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable
+ section 7 additional terms, to the whole of the work, and all
+ its parts, regardless of how they are packaged. This License
+ gives no permission to license the work in any other way, but
+ it does not invalidate such permission if you have separately
+ received it.
+
+ d. If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has
+ interactive interfaces that do not display Appropriate Legal
+ Notices, your work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+ works, which are not by their nature extensions of the covered
+ work, and which are not combined with it such as to form a larger
+ program, in or on a volume of a storage or distribution medium, is
+ called an "aggregate" if the compilation and its resulting
+ copyright are not used to limit the access or legal rights of the
+ compilation's users beyond what the individual works permit.
+ Inclusion of a covered work in an aggregate does not cause this
+ License to apply to the other parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+ of sections 4 and 5, provided that you also convey the
+ machine-readable Corresponding Source under the terms of this
+ License, in one of these ways:
+
+ a. Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b. Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for
+ as long as you offer spare parts or customer support for that
+ product model, to give anyone who possesses the object code
+ either (1) a copy of the Corresponding Source for all the
+ software in the product that is covered by this License, on a
+ durable physical medium customarily used for software
+ interchange, for a price no more than your reasonable cost of
+ physically performing this conveying of source, or (2) access
+ to copy the Corresponding Source from a network server at no
+ charge.
+
+ c. Convey individual copies of the object code with a copy of
+ the written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially,
+ and only if you received the object code with such an offer,
+ in accord with subsection 6b.
+
+ d. Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access
+ to the Corresponding Source in the same way through the same
+ place at no further charge. You need not require recipients
+ to copy the Corresponding Source along with the object code.
+ If the place to copy the object code is a network server, the
+ Corresponding Source may be on a different server (operated
+ by you or a third party) that supports equivalent copying
+ facilities, provided you maintain clear directions next to
+ the object code saying where to find the Corresponding Source.
+ Regardless of what server hosts the Corresponding Source, you
+ remain obligated to ensure that it is available for as long
+ as needed to satisfy these requirements.
+
+ e. Convey the object code using peer-to-peer transmission,
+ provided you inform other peers where the object code and
+ Corresponding Source of the work are being offered to the
+ general public at no charge under subsection 6d.
+
+
+ A separable portion of the object code, whose source code is
+ excluded from the Corresponding Source as a System Library, need
+ not be included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means
+ any tangible personal property which is normally used for personal,
+ family, or household purposes, or (2) anything designed or sold for
+ incorporation into a dwelling. In determining whether a product
+ is a consumer product, doubtful cases shall be resolved in favor of
+ coverage. For a particular product received by a particular user,
+ "normally used" refers to a typical or common use of that class of
+ product, regardless of the status of the particular user or of the
+ way in which the particular user actually uses, or expects or is
+ expected to use, the product. A product is a consumer product
+ regardless of whether the product has substantial commercial,
+ industrial or non-consumer uses, unless such uses represent the
+ only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+ procedures, authorization keys, or other information required to
+ install and execute modified versions of a covered work in that
+ User Product from a modified version of its Corresponding Source.
+ The information must suffice to ensure that the continued
+ functioning of the modified object code is in no case prevented or
+ interfered with solely because modification has been made.
+
+ If you convey an object code work under this section in, or with,
+ or specifically for use in, a User Product, and the conveying
+ occurs as part of a transaction in which the right of possession
+ and use of the User Product is transferred to the recipient in
+ perpetuity or for a fixed term (regardless of how the transaction
+ is characterized), the Corresponding Source conveyed under this
+ section must be accompanied by the Installation Information. But
+ this requirement does not apply if neither you nor any third party
+ retains the ability to install modified object code on the User
+ Product (for example, the work has been installed in ROM).
+
+ The requirement to provide Installation Information does not
+ include a requirement to continue to provide support service,
+ warranty, or updates for a work that has been modified or
+ installed by the recipient, or for the User Product in which it
+ has been modified or installed. Access to a network may be denied
+ when the modification itself materially and adversely affects the
+ operation of the network or violates the rules and protocols for
+ communication across the network.
+
+ Corresponding Source conveyed, and Installation Information
+ provided, in accord with this section must be in a format that is
+ publicly documented (and with an implementation available to the
+ public in source code form), and must require no special password
+ or key for unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of
+ this License by making exceptions from one or more of its
+ conditions. Additional permissions that are applicable to the
+ entire Program shall be treated as though they were included in
+ this License, to the extent that they are valid under applicable
+ law. If additional permissions apply only to part of the Program,
+ that part may be used separately under those permissions, but the
+ entire Program remains governed by this License without regard to
+ the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+ remove any additional permissions from that copy, or from any part
+ of it. (Additional permissions may be written to require their own
+ removal in certain cases when you modify the work.) You may place
+ additional permissions on material, added by you to a covered work,
+ for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material
+ you add to a covered work, you may (if authorized by the copyright
+ holders of that material) supplement the terms of this License
+ with terms:
+
+ a. Disclaiming warranty or limiting liability differently from
+ the terms of sections 15 and 16 of this License; or
+
+ b. Requiring preservation of specified reasonable legal notices
+ or author attributions in that material or in the Appropriate
+ Legal Notices displayed by works containing it; or
+
+ c. Prohibiting misrepresentation of the origin of that material,
+ or requiring that modified versions of such material be
+ marked in reasonable ways as different from the original
+ version; or
+
+ d. Limiting the use for publicity purposes of names of licensors
+ or authors of the material; or
+
+ e. Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f. Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified
+ versions of it) with contractual assumptions of liability to
+ the recipient, for any liability that these contractual
+ assumptions directly impose on those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+ restrictions" within the meaning of section 10. If the Program as
+ you received it, or any part of it, contains a notice stating that
+ it is governed by this License along with a term that is a further
+ restriction, you may remove that term. If a license document
+ contains a further restriction but permits relicensing or
+ conveying under this License, you may add to a covered work
+ material governed by the terms of that license document, provided
+ that the further restriction does not survive such relicensing or
+ conveying.
+
+ If you add terms to a covered work in accord with this section, you
+ must place, in the relevant source files, a statement of the
+ additional terms that apply to those files, or a notice indicating
+ where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in
+ the form of a separately written license, or stated as exceptions;
+ the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+ provided under this License. Any attempt otherwise to propagate or
+ modify it is void, and will automatically terminate your rights
+ under this License (including any patent licenses granted under
+ the third paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly
+ and finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from
+ you under this License. If your rights have been terminated and
+ not permanently reinstated, you do not qualify to receive new
+ licenses for the same material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+ run a copy of the Program. Ancillary propagation of a covered work
+ occurring solely as a consequence of using peer-to-peer
+ transmission to receive a copy likewise does not require
+ acceptance. However, nothing other than this License grants you
+ permission to propagate or modify any covered work. These actions
+ infringe copyright if you do not accept this License. Therefore,
+ by modifying or propagating a covered work, you indicate your
+ acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+ receives a license from the original licensors, to run, modify and
+ propagate that work, subject to this License. You are not
+ responsible for enforcing compliance by third parties with this
+ License.
+
+ An "entity transaction" is a transaction transferring control of an
+ organization, or substantially all assets of one, or subdividing an
+ organization, or merging organizations. If propagation of a
+ covered work results from an entity transaction, each party to that
+ transaction who receives a copy of the work also receives whatever
+ licenses to the work the party's predecessor in interest had or
+ could give under the previous paragraph, plus a right to
+ possession of the Corresponding Source of the work from the
+ predecessor in interest, if the predecessor has it or can get it
+ with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+ rights granted or affirmed under this License. For example, you
+ may not impose a license fee, royalty, or other charge for
+ exercise of rights granted under this License, and you may not
+ initiate litigation (including a cross-claim or counterclaim in a
+ lawsuit) alleging that any patent claim is infringed by making,
+ using, selling, offering for sale, or importing the Program or any
+ portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+ License of the Program or a work on which the Program is based.
+ The work thus licensed is called the contributor's "contributor
+ version".
+
+ A contributor's "essential patent claims" are all patent claims
+ owned or controlled by the contributor, whether already acquired or
+ hereafter acquired, that would be infringed by some manner,
+ permitted by this License, of making, using, or selling its
+ contributor version, but do not include claims that would be
+ infringed only as a consequence of further modification of the
+ contributor version. For purposes of this definition, "control"
+ includes the right to grant patent sublicenses in a manner
+ consistent with the requirements of this License.
+
+ Each contributor grants you a non-exclusive, worldwide,
+ royalty-free patent license under the contributor's essential
+ patent claims, to make, use, sell, offer for sale, import and
+ otherwise run, modify and propagate the contents of its
+ contributor version.
+
+ In the following three paragraphs, a "patent license" is any
+ express agreement or commitment, however denominated, not to
+ enforce a patent (such as an express permission to practice a
+ patent or covenant not to sue for patent infringement). To
+ "grant" such a patent license to a party means to make such an
+ agreement or commitment not to enforce a patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent
+ license, and the Corresponding Source of the work is not available
+ for anyone to copy, free of charge and under the terms of this
+ License, through a publicly available network server or other
+ readily accessible means, then you must either (1) cause the
+ Corresponding Source to be so available, or (2) arrange to deprive
+ yourself of the benefit of the patent license for this particular
+ work, or (3) arrange, in a manner consistent with the requirements
+ of this License, to extend the patent license to downstream
+ recipients. "Knowingly relying" means you have actual knowledge
+ that, but for the patent license, your conveying the covered work
+ in a country, or your recipient's use of the covered work in a
+ country, would infringe one or more identifiable patents in that
+ country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+ arrangement, you convey, or propagate by procuring conveyance of, a
+ covered work, and grant a patent license to some of the parties
+ receiving the covered work authorizing them to use, propagate,
+ modify or convey a specific copy of the covered work, then the
+ patent license you grant is automatically extended to all
+ recipients of the covered work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+ the scope of its coverage, prohibits the exercise of, or is
+ conditioned on the non-exercise of one or more of the rights that
+ are specifically granted under this License. You may not convey a
+ covered work if you are a party to an arrangement with a third
+ party that is in the business of distributing software, under
+ which you make payment to the third party based on the extent of
+ your activity of conveying the work, and under which the third
+ party grants, to any of the parties who would receive the covered
+ work from you, a discriminatory patent license (a) in connection
+ with copies of the covered work conveyed by you (or copies made
+ from those copies), or (b) primarily for and in connection with
+ specific products or compilations that contain the covered work,
+ unless you entered into that arrangement, or that patent license
+ was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+ any implied license or other defenses to infringement that may
+ otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order,
+ agreement or otherwise) that contradict the conditions of this
+ License, they do not excuse you from the conditions of this
+ License. If you cannot convey a covered work so as to satisfy
+ simultaneously your obligations under this License and any other
+ pertinent obligations, then as a consequence you may not convey it
+ at all. For example, if you agree to terms that obligate you to
+ collect a royalty for further conveying from those to whom you
+ convey the Program, the only way you could satisfy both those
+ terms and this License would be to refrain entirely from conveying
+ the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+ permission to link or combine any covered work with a work licensed
+ under version 3 of the GNU Affero General Public License into a
+ single combined work, and to convey the resulting work. The terms
+ of this License will continue to apply to the part which is the
+ covered work, but the special requirements of the GNU Affero
+ General Public License, section 13, concerning interaction through
+ a network will apply to the combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new
+ versions of the GNU General Public License from time to time.
+ Such new versions will be similar in spirit to the present
+ version, but may differ in detail to address new problems or
+ concerns.
+
+ Each version is given a distinguishing version number. If the
+ Program specifies that a certain numbered version of the GNU
+ General Public License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that numbered version or of any later version published by the
+ Free Software Foundation. If the Program does not specify a
+ version number of the GNU General Public License, you may choose
+ any version ever published by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+ versions of the GNU General Public License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Program.
+
+ Later license versions may give you additional or different
+ permissions. However, no additional obligations are imposed on any
+ author or copyright holder as a result of your choosing to follow a
+ later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+ APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
+ COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS"
+ WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+ INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+ MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE
+ RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
+ SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+ NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+ WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
+ AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU
+ FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+ CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
+ THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
+ BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+ PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+ PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF
+ THE POSSIBILITY OF SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+ above cannot be given local legal effect according to their terms,
+ reviewing courts shall apply local law that most closely
+ approximates an absolute waiver of all civil liability in
+ connection with the Program, unless a warranty or assumption of
+ liability accompanies a copy of the Program in return for a fee.

+terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least the

+
+1.1 Languages and Context-Free Grammars
+=======================================
+
+In order for Bison to parse a language, it must be described by a
+"context-free grammar". This means that you specify one or more
+"syntactic groupings" and give rules for constructing them from their
+parts. For example, in the C language, one kind of grouping is called
+an `expression'. One rule for making an expression might be, "An
+expression can be made of a minus sign and another expression".
+Another would be, "An expression can be an integer". As you can see,
+rules are often recursive, but there must be at least one rule which
+leads out of the recursion.
+
+ The most common formal system for presenting such rules for humans
+to read is "Backus-Naur Form" or "BNF", which was developed in order to
+specify the language Algol 60. Any grammar expressed in BNF is a
+context-free grammar. The input to Bison is essentially
+machine-readable BNF.
+
+ There are various important subclasses of context-free grammars.
+Although it can handle almost all context-free grammars, Bison is
+optimized for what are called LR(1) grammars. In brief, in these
+grammars, it must be possible to tell how to parse any portion of an
+input string with just a single token of lookahead. For historical
+reasons, Bison by default is limited by the additional restrictions of
+LALR(1), which is hard to explain simply. *Note Mysterious
+Conflicts::, for more information on this. As an experimental feature,
+you can escape these additional restrictions by requesting IELR(1) or
+canonical LR(1) parser tables. *Note LR Table Construction::, to learn
+how.
+
+ Parsers for LR(1) grammars are "deterministic", meaning roughly that
+the next grammar rule to apply at any point in the input is uniquely
+determined by the preceding input and a fixed, finite portion (called a
+"lookahead") of the remaining input. A context-free grammar can be
+"ambiguous", meaning that there are multiple ways to apply the grammar
+rules to get the same inputs. Even unambiguous grammars can be
+"nondeterministic", meaning that no fixed lookahead always suffices to
+determine the next grammar rule to apply. With the proper
+declarations, Bison is also able to parse these more general
+context-free grammars, using a technique known as GLR parsing (for
+Generalized LR). Bison's GLR parsers are able to handle any
+context-free grammar for which the number of possible parses of any
+given string is finite.
+
+ In the formal grammatical rules for a language, each kind of
+syntactic unit or grouping is named by a "symbol". Those which are
+built by grouping smaller constructs according to grammatical rules are
+called "nonterminal symbols"; those which can't be subdivided are called
+"terminal symbols" or "token types". We call a piece of input
+corresponding to a single terminal symbol a "token", and a piece
+corresponding to a single nonterminal symbol a "grouping".
+
+ We can use the C language as an example of what symbols, terminal and
+nonterminal, mean. The tokens of C are identifiers, constants (numeric
+and string), and the various keywords, arithmetic operators and
+punctuation marks. So the terminal symbols of a grammar for C include
+`identifier', `number', `string', plus one symbol for each keyword,
+operator or punctuation mark: `if', `return', `const', `static', `int',
+`char', `plus-sign', `open-brace', `close-brace', `comma' and many more.
+(These tokens can be subdivided into characters, but that is a matter of
+lexicography, not grammar.)
+
+ Here is a simple C function subdivided into tokens:
+
+ int /* keyword `int' */
+ square (int x) /* identifier, open-paren, keyword `int',
+ identifier, close-paren */
+ { /* open-brace */
+ return x * x; /* keyword `return', identifier, asterisk,
+ identifier, semicolon */
+ } /* close-brace */
+
+ The syntactic groupings of C include the expression, the statement,
+the declaration, and the function definition. These are represented in
+the grammar of C by nonterminal symbols `expression', `statement',
+`declaration' and `function definition'. The full grammar uses dozens
+of additional language constructs, each with its own nonterminal
+symbol, in order to express the meanings of these four. The example
+above is a function definition; it contains one declaration, and one
+statement. In the statement, each `x' is an expression and so is `x *
+x'.
+
+ Each nonterminal symbol must have grammatical rules showing how it
+is made out of simpler constructs. For example, one kind of C
+statement is the `return' statement; this would be described with a
+grammar rule which reads informally as follows:
+
+ A `statement' can be made of a `return' keyword, an `expression'
+ and a `semicolon'.
+
+There would be many other rules for `statement', one for each kind of
+statement in C.
+
+ One nonterminal symbol must be distinguished as the special one which
+defines a complete utterance in the language. It is called the "start
+symbol". In a compiler, this means a complete input program. In the C
+language, the nonterminal symbol `sequence of definitions and
+declarations' plays this role.
+
+ For example, `1 + 2' is a valid C expression--a valid part of a C
+program--but it is not valid as an _entire_ C program. In the
+context-free grammar of C, this follows from the fact that `expression'
+is not the start symbol.
+
+ The Bison parser reads a sequence of tokens as its input, and groups
+the tokens using the grammar rules. If the input is valid, the end
+result is that the entire token sequence reduces to a single grouping
+whose symbol is the grammar's start symbol. If we use a grammar for C,
+the entire input must be a `sequence of definitions and declarations'.
+If not, the parser reports a syntax error.

+
+1.2 From Formal Rules to Bison Input
+====================================
+
+A formal grammar is a mathematical construct. To define the language
+for Bison, you must write a file expressing the grammar in Bison syntax:
+a "Bison grammar" file. *Note Bison Grammar Files: Grammar File.
+
+ A nonterminal symbol in the formal grammar is represented in Bison
+input as an identifier, like an identifier in C. By convention, it
+should be in lower case, such as `expr', `stmt' or `declaration'.
+
+ The Bison representation for a terminal symbol is also called a
+"token type". Token types as well can be represented as C-like
+identifiers. By convention, these identifiers should be upper case to
+distinguish them from nonterminals: for example, `INTEGER',
+`IDENTIFIER', `IF' or `RETURN'. A terminal symbol that stands for a
+particular keyword in the language should be named after that keyword
+converted to upper case. The terminal symbol `error' is reserved for
+error recovery. *Note Symbols::.
+
+ A terminal symbol can also be represented as a character literal,
+just like a C character constant. You should do this whenever a token
+is just a single character (parenthesis, plus-sign, etc.): use that
+same character in a literal as the terminal symbol for that token.
+
+ A third way to represent a terminal symbol is with a C string
+constant containing several characters. *Note Symbols::, for more
+information.
+
+ The grammar rules also have an expression in Bison syntax. For
+example, here is the Bison rule for a C `return' statement. The
+semicolon in quotes is a literal character token, representing part of
+the C syntax for the statement; the naked semicolon, and the colon, are
+Bison punctuation used in every rule.
+
+ stmt: RETURN expr ';' ;
+
+*Note Syntax of Grammar Rules: Rules.
+
+\1f
+File: bison.info, Node: Semantic Values, Next: Semantic Actions, Prev: Grammar in Bison, Up: Concepts
+
+1.3 Semantic Values
+===================
+
+A formal grammar selects tokens only by their classifications: for
+example, if a rule mentions the terminal symbol `integer constant', it
+means that _any_ integer constant is grammatically valid in that
+position. The precise value of the constant is irrelevant to how to
+parse the input: if `x+4' is grammatical then `x+1' or `x+3989' is
+equally grammatical.
+
+ But the precise value is very important for what the input means
+once it is parsed. A compiler is useless if it fails to distinguish
+between 4, 1 and 3989 as constants in the program! Therefore, each
+token in a Bison grammar has both a token type and a "semantic value".
+*Note Defining Language Semantics: Semantics, for details.
+
+ The token type is a terminal symbol defined in the grammar, such as
+`INTEGER', `IDENTIFIER' or `',''. It tells everything you need to know
+to decide where the token may validly appear and how to group it with
+other tokens. The grammar rules know nothing about tokens except their
+types.
+
+ The semantic value has all the rest of the information about the
+meaning of the token, such as the value of an integer, or the name of an
+identifier. (A token such as `','' which is just punctuation doesn't
+need to have any semantic value.)
+
+ For example, an input token might be classified as token type
+`INTEGER' and have the semantic value 4. Another input token might
+have the same token type `INTEGER' but value 3989. When a grammar rule
+says that `INTEGER' is allowed, either of these tokens is acceptable
+because each is an `INTEGER'. When the parser accepts the token, it
+keeps track of the token's semantic value.
+
+ Each grouping can also have a semantic value as well as its
+nonterminal symbol. For example, in a calculator, an expression
+typically has a semantic value that is a number. In a compiler for a
+programming language, an expression typically has a semantic value that
+is a tree structure describing the meaning of the expression.
+
+\1f
+File: bison.info, Node: Semantic Actions, Next: GLR Parsers, Prev: Semantic Values, Up: Concepts
+
+1.4 Semantic Actions
+====================
+
+In order to be useful, a program must do more than parse input; it must
+also produce some output based on the input. In a Bison grammar, a
+grammar rule can have an "action" made up of C statements. Each time
+the parser recognizes a match for that rule, the action is executed.
+*Note Actions::.
+
+ Most of the time, the purpose of an action is to compute the
+semantic value of the whole construct from the semantic values of its
+parts. For example, suppose we have a rule which says an expression
+can be the sum of two expressions. When the parser recognizes such a
+sum, each of the subexpressions has a semantic value which describes
+how it was built up. The action for this rule should create a similar
+sort of value for the newly recognized larger expression.
+
+ For example, here is a rule that says an expression can be the sum of
+two subexpressions:
+
+ expr: expr '+' expr { $$ = $1 + $3; } ;
+
+The action says how to produce the semantic value of the sum expression
+from the values of the two subexpressions.
+
+\1f

+
+1.5 Writing GLR Parsers
+=======================
+
+In some grammars, Bison's deterministic LR(1) parsing algorithm cannot
+decide whether to apply a certain grammar rule at a given point. That
+is, it may not be able to decide (on the basis of the input read so
+far) which of two possible reductions (applications of a grammar rule)
+applies, or whether to apply a reduction or read more of the input and
+apply a reduction later in the input. These are known respectively as
+"reduce/reduce" conflicts (*note Reduce/Reduce::), and "shift/reduce"
+conflicts (*note Shift/Reduce::).
+
+ To use a grammar that is not easily modified to be LR(1), a more
+general parsing algorithm is sometimes necessary. If you include
+`%glr-parser' among the Bison declarations in your file (*note Grammar
+Outline::), the result is a Generalized LR (GLR) parser. These parsers
+handle Bison grammars that contain no unresolved conflicts (i.e., after
+applying precedence declarations) identically to deterministic parsers.
+However, when faced with unresolved shift/reduce and reduce/reduce
+conflicts, GLR parsers use the simple expedient of doing both,
+effectively cloning the parser to follow both possibilities. Each of
+the resulting parsers can again split, so that at any given time, there
+can be any number of possible parses being explored. The parsers
+proceed in lockstep; that is, all of them consume (shift) a given input
+symbol before any of them proceed to the next. Each of the cloned
+parsers eventually meets one of two possible fates: either it runs into
+a parsing error, in which case it simply vanishes, or it merges with
+another parser, because the two of them have reduced the input to an
+identical set of symbols.
+
+ During the time that there are multiple parsers, semantic actions are
+recorded, but not performed. When a parser disappears, its recorded
+semantic actions disappear as well, and are never performed. When a
+reduction makes two parsers identical, causing them to merge, Bison
+records both sets of semantic actions. Whenever the last two parsers
+merge, reverting to the single-parser case, Bison resolves all the
+outstanding actions either by precedences given to the grammar rules
+involved, or by performing both actions, and then calling a designated
+user-defined function on the resulting values to produce an arbitrary
+merged result.

+
+1.5.1 Using GLR on Unambiguous Grammars
+---------------------------------------
+
+In the simplest cases, you can use the GLR algorithm to parse grammars
+that are unambiguous but fail to be LR(1). Such grammars typically
+require more than one symbol of lookahead.
+
+ Consider a problem that arises in the declaration of enumerated and
+subrange types in the programming language Pascal. Here are some
+examples:
+
+ type subrange = lo .. hi;
+ type enum = (a, b, c);
+
+The original language standard allows only numeric literals and
+constant identifiers for the subrange bounds (`lo' and `hi'), but
+Extended Pascal (ISO/IEC 10206) and many other Pascal implementations
+allow arbitrary expressions there. This gives rise to the following
+situation, containing a superfluous pair of parentheses:
+
+ type subrange = (a) .. b;
+
+Compare this to the following declaration of an enumerated type with
+only one value:
+
+ type enum = (a);
+
+(These declarations are contrived, but they are syntactically valid,
+and more-complicated cases can come up in practical programs.)
+
+ These two declarations look identical until the `..' token. With
+normal LR(1) one-token lookahead it is not possible to decide between
+the two forms when the identifier `a' is parsed. It is, however,
+desirable for a parser to decide this, since in the latter case `a'
+must become a new identifier to represent the enumeration value, while
+in the former case `a' must be evaluated with its current meaning,
+which may be a constant or even a function call.
+
+ You could parse `(a)' as an "unspecified identifier in parentheses",
+to be resolved later, but this typically requires substantial
+contortions in both semantic actions and large parts of the grammar,
+where the parentheses are nested in the recursive rules for expressions.
+
+ You might think of using the lexer to distinguish between the two
+forms by returning different tokens for currently defined and undefined
+identifiers. But if these declarations occur in a local scope, and `a'
+is defined in an outer scope, then both forms are possible--either
+locally redefining `a', or using the value of `a' from the outer scope.
+So this approach cannot work.
+
+ A simple solution to this problem is to declare the parser to use
+the GLR algorithm. When the GLR parser reaches the critical state, it
+merely splits into two branches and pursues both syntax rules
+simultaneously. Sooner or later, one of them runs into a parsing
+error. If there is a `..' token before the next `;', the rule for
+enumerated types fails since it cannot accept `..' anywhere; otherwise,
+the subrange type rule fails since it requires a `..' token. So one of
+the branches fails silently, and the other one continues normally,
+performing all the intermediate actions that were postponed during the
+split.
+
+ If the input is syntactically incorrect, both branches fail and the
+parser reports a syntax error as usual.
+
+ The effect of all this is that the parser seems to "guess" the
+correct branch to take, or in other words, it seems to use more
+lookahead than the underlying LR(1) algorithm actually allows for. In
+this example, LR(2) would suffice, but also some cases that are not
+LR(k) for any k can be handled this way.
+
+ In general, a GLR parser can take quadratic or cubic worst-case time,
+and the current Bison parser even takes exponential time and space for
+some grammars. In practice, this rarely happens, and for many grammars
+it is possible to prove that it cannot happen. The present example
+contains only one conflict between two rules, and the type-declaration
+context containing the conflict cannot be nested. So the number of
+branches that can exist at any time is limited by the constant 2, and
+the parsing time is still linear.
+
+ Here is a Bison grammar corresponding to the example above. It
+parses a vastly simplified form of Pascal type declarations.
+
+ %token TYPE DOTDOT ID
+
+ %left '+' '-'
+ %left '*' '/'
+
+ %%
+
+ type_decl: TYPE ID '=' type ';' ;
+
+ type:
+ '(' id_list ')'
+ | expr DOTDOT expr
+ ;
+
+ id_list:
+ ID
+ | id_list ',' ID
+ ;
+
+ expr:
+ '(' expr ')'
+ | expr '+' expr
+ | expr '-' expr
+ | expr '*' expr
+ | expr '/' expr
+ | ID
+ ;
+
+ When used as a normal LR(1) grammar, Bison correctly complains about
+one reduce/reduce conflict. In the conflicting situation the parser
+chooses one of the alternatives, arbitrarily the one declared first.
+Therefore the following correct input is not recognized:
+
+ type t = (a) .. b;
+
+ The parser can be turned into a GLR parser, while also telling Bison
+to be silent about the one known reduce/reduce conflict, by adding
+these two declarations to the Bison grammar file (before the first
+`%%'):
+
+ %glr-parser
+ %expect-rr 1
+
+No change in the grammar itself is required. Now the parser recognizes
+all valid declarations, according to the limited syntax above,
+transparently. In fact, the user does not even notice when the parser
+splits.
+
+ So here we have a case where we can use the benefits of GLR, almost
+without disadvantages. Even in simple cases like this, however, there
+are at least two potential problems to beware. First, always analyze
+the conflicts reported by Bison to make sure that GLR splitting is only
+done where it is intended. A GLR parser splitting inadvertently may
+cause problems less obvious than an LR parser statically choosing the
+wrong alternative in a conflict. Second, consider interactions with
+the lexer (*note Semantic Tokens::) with great care. Since a split
+parser consumes tokens without performing any actions during the split,
+the lexer cannot obtain information via parser actions. Some cases of
+lexer interactions can be eliminated by using GLR to shift the
+complications from the lexer to the parser. You must check the
+remaining cases for correctness.
+
+ In our example, it would be safe for the lexer to return tokens
+based on their current meanings in some symbol table, because no new
+symbols are defined in the middle of a type declaration. Though it is
+possible for a parser to define the enumeration constants as they are
+parsed, before the type declaration is completed, it actually makes no
+difference since they cannot be used within the same enumerated type
+declaration.

+
+1.5.2 Using GLR to Resolve Ambiguities
+--------------------------------------
+
+Let's consider an example, vastly simplified from a C++ grammar.
+
+ %{
+ #include <stdio.h>
+ #define YYSTYPE char const *
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+
+ %token TYPENAME ID
+
+ %right '='
+ %left '+'
+
+ %glr-parser
+
+ %%
+
+ prog:
+ /* Nothing. */
+ | prog stmt { printf ("\n"); }
+ ;
+
+ stmt:
+ expr ';' %dprec 1
+ | decl %dprec 2
+ ;
+
+ expr:
+ ID { printf ("%s ", $$); }
+ | TYPENAME '(' expr ')'
+ { printf ("%s <cast> ", $1); }
+ | expr '+' expr { printf ("+ "); }
+ | expr '=' expr { printf ("= "); }
+ ;
+
+ decl:
+ TYPENAME declarator ';'
+ { printf ("%s <declare> ", $1); }
+ | TYPENAME declarator '=' expr ';'
+ { printf ("%s <init-declare> ", $1); }
+ ;
+
+ declarator:
+ ID { printf ("\"%s\" ", $1); }
+ | '(' declarator ')'
+ ;
+
+This models a problematic part of the C++ grammar--the ambiguity between
+certain declarations and statements. For example,
+
+ T (x) = y+z;
+
+parses as either an `expr' or a `stmt' (assuming that `T' is recognized
+as a `TYPENAME' and `x' as an `ID'). Bison detects this as a
+reduce/reduce conflict between the rules `expr : ID' and `declarator :
+ID', which it cannot resolve at the time it encounters `x' in the
+example above. Since this is a GLR parser, it therefore splits the
+problem into two parses, one for each choice of resolving the
+reduce/reduce conflict. Unlike the example from the previous section
+(*note Simple GLR Parsers::), however, neither of these parses "dies,"
+because the grammar as it stands is ambiguous. One of the parsers
+eventually reduces `stmt : expr ';'' and the other reduces `stmt :
+decl', after which both parsers are in an identical state: they've seen
+`prog stmt' and have the same unprocessed input remaining. We say that
+these parses have "merged."
+
+ At this point, the GLR parser requires a specification in the
+grammar of how to choose between the competing parses. In the example
+above, the two `%dprec' declarations specify that Bison is to give
+precedence to the parse that interprets the example as a `decl', which
+implies that `x' is a declarator. The parser therefore prints
+
+ "x" y z + T <init-declare>
+
+ The `%dprec' declarations only come into play when more than one
+parse survives. Consider a different input string for this parser:
+
+ T (x) + y;
+
+This is another example of using GLR to parse an unambiguous construct,
+as shown in the previous section (*note Simple GLR Parsers::). Here,
+there is no ambiguity (this cannot be parsed as a declaration).
+However, at the time the Bison parser encounters `x', it does not have
+enough information to resolve the reduce/reduce conflict (again,
+between `x' as an `expr' or a `declarator'). In this case, no
+precedence declaration is used. Again, the parser splits into two, one
+assuming that `x' is an `expr', and the other assuming `x' is a
+`declarator'. The second of these parsers then vanishes when it sees
+`+', and the parser prints
+
+ x T <cast> y +
+
+ Suppose that instead of resolving the ambiguity, you wanted to see
+all the possibilities. For this purpose, you must merge the semantic
+actions of the two possible parsers, rather than choosing one over the
+other. To do so, you could change the declaration of `stmt' as follows:
+
+ stmt:
+ expr ';' %merge <stmtMerge>
+ | decl %merge <stmtMerge>
+ ;
+
+and define the `stmtMerge' function as:
+
+ static YYSTYPE
+ stmtMerge (YYSTYPE x0, YYSTYPE x1)
+ {
+ printf ("<OR> ");
+ return "";
+ }
+
+with an accompanying forward declaration in the C declarations at the
+beginning of the file:
+
+ %{
+ #define YYSTYPE char const *
+ static YYSTYPE stmtMerge (YYSTYPE x0, YYSTYPE x1);
+ %}
+
+With these declarations, the resulting parser parses the first example
+as both an `expr' and a `decl', and prints
+
+ "x" y z + T <init-declare> x T <cast> y z + = <OR>
+
+ Bison requires that all of the productions that participate in any
+particular merge have identical `%merge' clauses. Otherwise, the
+ambiguity would be unresolvable, and the parser will report an error
+during any parse that results in the offending merge.

+
+1.5.3 GLR Semantic Actions
+--------------------------
+
+By definition, a deferred semantic action is not performed at the same
+time as the associated reduction. This raises caveats for several
+Bison features you might use in a semantic action in a GLR parser.
+
+ In any semantic action, you can examine `yychar' to determine the
+type of the lookahead token present at the time of the associated
+reduction. After checking that `yychar' is not set to `YYEMPTY' or
+`YYEOF', you can then examine `yylval' and `yylloc' to determine the
+lookahead token's semantic value and location, if any. In a
+nondeferred semantic action, you can also modify any of these variables
+to influence syntax analysis. *Note Lookahead Tokens: Lookahead.
+
+ In a deferred semantic action, it's too late to influence syntax
+analysis. In this case, `yychar', `yylval', and `yylloc' are set to
+shallow copies of the values they had at the time of the associated
+reduction. For this reason alone, modifying them is dangerous.
+Moreover, the result of modifying them is undefined and subject to
+change with future versions of Bison. For example, if a semantic
+action might be deferred, you should never write it to invoke
+`yyclearin' (*note Action Features::) or to attempt to free memory
+referenced by `yylval'.
+
+ Another Bison feature requiring special consideration is `YYERROR'
+(*note Action Features::), which you can invoke in a semantic action to
+initiate error recovery. During deterministic GLR operation, the
+effect of `YYERROR' is the same as its effect in a deterministic parser.
+In a deferred semantic action, its effect is undefined.
+
+ Also, see *note Default Action for Locations: Location Default
+Action, which describes a special usage of `YYLLOC_DEFAULT' in GLR
+parsers.
+

+File: bison.info, Node: Compiler Requirements, Prev: GLR Semantic Actions, Up: GLR Parsers
+
+1.5.4 Considerations when Compiling GLR Parsers
+-----------------------------------------------
+
+The GLR parsers require a compiler for ISO C89 or later. In addition,
+they use the `inline' keyword, which is not C89, but is C99 and is a
+common extension in pre-C99 compilers. It is up to the user of these
+parsers to handle portability issues. For instance, if using Autoconf
+and the Autoconf macro `AC_C_INLINE', a mere
+
+ %{
+ #include <config.h>
+ %}
+
+will suffice. Otherwise, we suggest
+
+ %{
+ #if (__STDC_VERSION__ < 199901 && ! defined __GNUC__ \
+ && ! defined inline)
+ # define inline
+ #endif
+ %}
+
+\1f
+File: bison.info, Node: Locations, Next: Bison Parser, Prev: GLR Parsers, Up: Concepts
+
+1.6 Locations
+=============
+
+Many applications, like interpreters or compilers, have to produce
+verbose and useful error messages. To achieve this, one must be able
+to keep track of the "textual location", or "location", of each
+syntactic construct. Bison provides a mechanism for handling these
+locations.
+
+ Each token has a semantic value. In a similar fashion, each token
+has an associated location, but the type of locations is the same for
+all tokens and groupings. Moreover, the output parser is equipped with
+a default data structure for storing locations (*note Tracking
+Locations::, for more details).
+
+ Like semantic values, locations can be reached in actions using a
+dedicated set of constructs. In the example above, the location of the
+whole grouping is `@$', while the locations of the subexpressions are
+`@1' and `@3'.
+
+ When a rule is matched, a default action is used to compute the
+semantic value of its left hand side (*note Actions::). In the same
+way, another default action is used for locations. However, the action
+for locations is general enough for most cases, meaning there is
+usually no need to describe for each rule how `@$' should be formed.
+When building a new location for a given grouping, the default behavior
+of the output parser is to take the beginning of the first symbol, and
+the end of the last symbol.

+
+1.7 Bison Output: the Parser Implementation File
+================================================
+
+When you run Bison, you give it a Bison grammar file as input. The
+most important output is a C source file that implements a parser for
+the language described by the grammar. This parser is called a "Bison
+parser", and this file is called a "Bison parser implementation file".
+Keep in mind that the Bison utility and the Bison parser are two
+distinct programs: the Bison utility is a program whose output is the
+Bison parser implementation file that becomes part of your program.
+
+ The job of the Bison parser is to group tokens into groupings
+according to the grammar rules--for example, to build identifiers and
+operators into expressions. As it does this, it runs the actions for
+the grammar rules it uses.
+
+ The tokens come from a function called the "lexical analyzer" that
+you must supply in some fashion (such as by writing it in C). The Bison
+parser calls the lexical analyzer each time it wants a new token. It
+doesn't know what is "inside" the tokens (though their semantic values
+may reflect this). Typically the lexical analyzer makes the tokens by
+parsing characters of text, but Bison does not depend on this. *Note
+The Lexical Analyzer Function `yylex': Lexical.
+
+ The Bison parser implementation file is C code which defines a
+function named `yyparse' which implements that grammar. This function
+does not make a complete C program: you must supply some additional
+functions. One is the lexical analyzer. Another is an error-reporting
+function which the parser calls to report an error. In addition, a
+complete C program must start with a function called `main'; you have
+to provide this, and arrange for it to call `yyparse' or the parser
+will never run. *Note Parser C-Language Interface: Interface.
+
+ Aside from the token type names and the symbols in the actions you
+write, all symbols defined in the Bison parser implementation file
+itself begin with `yy' or `YY'. This includes interface functions such
+as the lexical analyzer function `yylex', the error reporting function
+`yyerror' and the parser function `yyparse' itself. This also includes
+numerous identifiers used for internal purposes. Therefore, you should
+avoid using C identifiers starting with `yy' or `YY' in the Bison
+grammar file except for the ones defined in this manual. Also, you
+should avoid using the C identifiers `malloc' and `free' for anything
+other than their usual meanings.
+
+ In some cases the Bison parser implementation file includes system
+headers, and in those cases your code should respect the identifiers
+reserved by those headers. On some non-GNU hosts, `<alloca.h>',
+`<malloc.h>', `<stddef.h>', and `<stdlib.h>' are included as needed to
+declare memory allocators and related types. `<libintl.h>' is included
+if message translation is in use (*note Internationalization::). Other
+system headers may be included if you define `YYDEBUG' to a nonzero
+value (*note Tracing Your Parser: Tracing.).
+

+File: bison.info, Node: Stages, Next: Grammar Layout, Prev: Bison Parser, Up: Concepts
+
+1.8 Stages in Using Bison
+=========================
+
+The actual language-design process using Bison, from grammar
+specification to a working compiler or interpreter, has these parts:
+
+ 1. Formally specify the grammar in a form recognized by Bison (*note
+ Bison Grammar Files: Grammar File.). For each grammatical rule in
+ the language, describe the action that is to be taken when an
+ instance of that rule is recognized. The action is described by a
+ sequence of C statements.
+
+ 2. Write a lexical analyzer to process input and pass tokens to the
+ parser. The lexical analyzer may be written by hand in C (*note
+ The Lexical Analyzer Function `yylex': Lexical.). It could also
+ be produced using Lex, but the use of Lex is not discussed in this
+ manual.
+
+ 3. Write a controlling function that calls the Bison-produced parser.
+
+ 4. Write error-reporting routines.
+
+ To turn this source code as written into a runnable program, you
+must follow these steps:
+
+ 1. Run Bison on the grammar to produce the parser.
+
+ 2. Compile the code output by Bison, as well as any other source
+ files.
+
+ 3. Link the object files to produce the finished product.
+
+\1f
+File: bison.info, Node: Grammar Layout, Prev: Stages, Up: Concepts
+
+1.9 The Overall Layout of a Bison Grammar
+=========================================
+
+The input file for the Bison utility is a "Bison grammar file". The
+general form of a Bison grammar file is as follows:
+
+ %{
+ PROLOGUE
+ %}
+
+ BISON DECLARATIONS
+
+ %%
+ GRAMMAR RULES
+ %%
+ EPILOGUE
+
+The `%%', `%{' and `%}' are punctuation that appears in every Bison
+grammar file to separate the sections.
+
+ The prologue may define types and variables used in the actions.
+You can also use preprocessor commands to define macros used there, and
+use `#include' to include header files that do any of these things.
+You need to declare the lexical analyzer `yylex' and the error printer
+`yyerror' here, along with any other global identifiers used by the
+actions in the grammar rules.
+
+ The Bison declarations declare the names of the terminal and
+nonterminal symbols, and may also describe operator precedence and the
+data types of semantic values of various symbols.
+
+ The grammar rules define how to construct each nonterminal symbol
+from its parts.
+
+ The epilogue can contain any code you want to use. Often the
+definitions of functions declared in the prologue go here. In a simple
+program, all the rest of the program can go here.

+======================================

+example provides a good starting point, since operator precedence is
+not an issue. The second example will illustrate how operator

+
+2.1.1 Declarations for `rpcalc'
+-------------------------------
+
+Here are the C and Bison declarations for the reverse polish notation
+calculator. As in C, comments are placed between `/*...*/'.
+
+ /* Reverse polish notation calculator. */
+
+ %{
+ #define YYSTYPE double
+ #include <math.h>
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+
+ %token NUM
+
+ %% /* Grammar rules and actions follow. */
+
+ The declarations section (*note The prologue: Prologue.) contains two
+preprocessor directives and two forward declarations.
+
+ The `#define' directive defines the macro `YYSTYPE', thus specifying
+the C data type for semantic values of both tokens and groupings (*note
+Data Types of Semantic Values: Value Type.). The Bison parser will use
+whatever type `YYSTYPE' is defined as; if you don't define it, `int' is
+the default. Because we specify `double', each token and each
+expression has an associated value, which is a floating point number.
+
+ The `#include' directive is used to declare the exponentiation
+function `pow'.
+
+ The forward declarations for `yylex' and `yyerror' are needed
+because the C language requires that functions be declared before they
+are used. These functions will be defined in the epilogue, but the
+parser calls them so they must be declared in the prologue.
+
+ The second section, Bison declarations, provides information to Bison
+about the token types (*note The Bison Declarations Section: Bison
+Declarations.). Each terminal symbol that is not a single-character
+literal must be declared here. (Single-character literals normally
+don't need to be declared.) In this example, all the arithmetic
+operators are designated by single-character literals, so the only
+terminal symbol that needs to be declared is `NUM', the token type for
+numeric constants.
+

+
+2.1.2 Grammar Rules for `rpcalc'
+--------------------------------
+
+Here are the grammar rules for the reverse polish notation calculator.
+
+ input:
+ /* empty */
+ | input line
+ ;
+
+ line:
+ '\n'
+ | exp '\n' { printf ("%.10g\n", $1); }
+ ;
+
+ exp:
+ NUM { $$ = $1; }
+ | exp exp '+' { $$ = $1 + $2; }
+ | exp exp '-' { $$ = $1 - $2; }
+ | exp exp '*' { $$ = $1 * $2; }
+ | exp exp '/' { $$ = $1 / $2; }
+ | exp exp '^' { $$ = pow ($1, $2); } /* Exponentiation */
+ | exp 'n' { $$ = -$1; } /* Unary minus */
+ ;
+ %%
+
+ The groupings of the rpcalc "language" defined here are the
+expression (given the name `exp'), the line of input (`line'), and the
+complete input transcript (`input'). Each of these nonterminal symbols
+has several alternate rules, joined by the vertical bar `|' which is
+read as "or". The following sections explain what these rules mean.
+
+ The semantics of the language is determined by the actions taken
+when a grouping is recognized. The actions are the C code that appears
+inside braces. *Note Actions::.
+
+ You must specify these actions in C, but Bison provides the means for
+passing semantic values between the rules. In each action, the
+pseudo-variable `$$' stands for the semantic value for the grouping
+that the rule is going to construct. Assigning a value to `$$' is the
+main job of most actions. The semantic values of the components of the
+rule are referred to as `$1', `$2', and so on.

+
+2.1.2.1 Explanation of `input'
+..............................
+
+Consider the definition of `input':
+
+ input:
+ /* empty */
+ | input line
+ ;
+
+ This definition reads as follows: "A complete input is either an
+empty string, or a complete input followed by an input line". Notice
+that "complete input" is defined in terms of itself. This definition
+is said to be "left recursive" since `input' appears always as the
+leftmost symbol in the sequence. *Note Recursive Rules: Recursion.
+
+ The first alternative is empty because there are no symbols between
+the colon and the first `|'; this means that `input' can match an empty
+string of input (no tokens). We write the rules this way because it is
+legitimate to type `Ctrl-d' right after you start the calculator. It's
+conventional to put an empty alternative first and write the comment
+`/* empty */' in it.
+
+ The second alternate rule (`input line') handles all nontrivial
+input. It means, "After reading any number of lines, read one more
+line if possible." The left recursion makes this rule into a loop.
+Since the first alternative matches empty input, the loop can be
+executed zero or more times.
+
+ The parser function `yyparse' continues to process input until a
+grammatical error is seen or the lexical analyzer says there are no more
+input tokens; we will arrange for the latter to happen at end-of-input.
+

+
+2.1.2.2 Explanation of `line'
+.............................
+
+Now consider the definition of `line':
+
+ line:
+ '\n'
+ | exp '\n' { printf ("%.10g\n", $1); }
+ ;
+
+ The first alternative is a token which is a newline character; this
+means that rpcalc accepts a blank line (and ignores it, since there is
+no action). The second alternative is an expression followed by a
+newline. This is the alternative that makes rpcalc useful. The
+semantic value of the `exp' grouping is the value of `$1' because the
+`exp' in question is the first symbol in the alternative. The action
+prints this value, which is the result of the computation the user
+asked for.
+
+ This action is unusual because it does not assign a value to `$$'.
+As a consequence, the semantic value associated with the `line' is
+uninitialized (its value will be unpredictable). This would be a bug if
+that value were ever used, but we don't use it: once rpcalc has printed
+the value of the user's input line, that value is no longer needed.
+
+\1f
+File: bison.info, Node: Rpcalc Expr, Prev: Rpcalc Line, Up: Rpcalc Rules
+
+2.1.2.3 Explanation of `expr'
+.............................
+
+The `exp' grouping has several rules, one for each kind of expression.
+The first rule handles the simplest expressions: those that are just
+numbers. The second handles an addition-expression, which looks like
+two expressions followed by a plus-sign. The third handles
+subtraction, and so on.
+
+ exp:
+ NUM
+ | exp exp '+' { $$ = $1 + $2; }
+ | exp exp '-' { $$ = $1 - $2; }
+ ...
+ ;
+
+ We have used `|' to join all the rules for `exp', but we could
+equally well have written them separately:
+
+ exp: NUM ;
+ exp: exp exp '+' { $$ = $1 + $2; };
+ exp: exp exp '-' { $$ = $1 - $2; };
+ ...
+
+ Most of the rules have actions that compute the value of the
+expression in terms of the value of its parts. For example, in the
+rule for addition, `$1' refers to the first component `exp' and `$2'
+refers to the second one. The third component, `'+'', has no meaningful
+associated semantic value, but if it had one you could refer to it as
+`$3'. When `yyparse' recognizes a sum expression using this rule, the
+sum of the two subexpressions' values is produced as the value of the
+entire expression. *Note Actions::.
+
+ You don't have to give an action for every rule. When a rule has no
+action, Bison by default copies the value of `$1' into `$$'. This is
+what happens in the first rule (the one that uses `NUM').
+
+ The formatting shown here is the recommended convention, but Bison
+does not require it. You can add or change white space as much as you
+wish. For example, this:
+
+ exp: NUM | exp exp '+' {$$ = $1 + $2; } | ... ;
+
+means the same thing as this:
+
+ exp:
+ NUM
+ | exp exp '+' { $$ = $1 + $2; }
+ | ...
+ ;
+
+The latter, however, is much more readable.

+
+2.1.3 The `rpcalc' Lexical Analyzer
+-----------------------------------
+
+The lexical analyzer's job is low-level parsing: converting characters
+or sequences of characters into tokens. The Bison parser gets its
+tokens by calling the lexical analyzer. *Note The Lexical Analyzer
+Function `yylex': Lexical.
+
+ Only a simple lexical analyzer is needed for the RPN calculator.
+This lexical analyzer skips blanks and tabs, then reads in numbers as
+`double' and returns them as `NUM' tokens. Any other character that
+isn't part of a number is a separate token. Note that the token-code
+for such a single-character token is the character itself.
+
+ The return value of the lexical analyzer function is a numeric code
+which represents a token type. The same text used in Bison rules to
+stand for this token type is also a C expression for the numeric code
+for the type. This works in two ways. If the token type is a
+character literal, then its numeric code is that of the character; you
+can use the same character literal in the lexical analyzer to express
+the number. If the token type is an identifier, that identifier is
+defined by Bison as a C macro whose definition is the appropriate
+number. In this example, therefore, `NUM' becomes a macro for `yylex'
+to use.
+
+ The semantic value of the token (if it has one) is stored into the
+global variable `yylval', which is where the Bison parser will look for
+it. (The C data type of `yylval' is `YYSTYPE', which was defined at
+the beginning of the grammar; *note Declarations for `rpcalc': Rpcalc
+Declarations.)
+
+ A token type code of zero is returned if the end-of-input is
+encountered. (Bison recognizes any nonpositive value as indicating
+end-of-input.)
+
+ Here is the code for the lexical analyzer:
+
+ /* The lexical analyzer returns a double floating point
+ number on the stack and the token NUM, or the numeric code
+ of the character read if not a number. It skips all blanks
+ and tabs, and returns 0 for end-of-input. */
+
+ #include <ctype.h>
+
+ int
+ yylex (void)
+ {
+ int c;
+
+ /* Skip white space. */
+ while ((c = getchar ()) == ' ' || c == '\t')
+ continue;
+ /* Process numbers. */
+ if (c == '.' || isdigit (c))
+ {
+ ungetc (c, stdin);
+ scanf ("%lf", &yylval);
+ return NUM;
+ }
+ /* Return end-of-input. */
+ if (c == EOF)
+ return 0;
+ /* Return a single char. */
+ return c;
+ }

+
+2.1.4 The Controlling Function
+------------------------------
+
+In keeping with the spirit of this example, the controlling function is
+kept to the bare minimum. The only requirement is that it call
+`yyparse' to start the process of parsing.
+
+ int
+ main (void)
+ {
+ return yyparse ();
+ }
+
+\1f
+File: bison.info, Node: Rpcalc Error, Next: Rpcalc Generate, Prev: Rpcalc Main, Up: RPN Calc
+
+2.1.5 The Error Reporting Routine
+---------------------------------
+
+When `yyparse' detects a syntax error, it calls the error reporting
+function `yyerror' to print an error message (usually but not always
+`"syntax error"'). It is up to the programmer to supply `yyerror'
+(*note Parser C-Language Interface: Interface.), so here is the
+definition we will use:
+
+ #include <stdio.h>
+
+ /* Called by yyparse on error. */
+ void
+ yyerror (char const *s)
+ {
+ fprintf (stderr, "%s\n", s);
+ }
+
+ After `yyerror' returns, the Bison parser may recover from the error
+and continue parsing if the grammar contains a suitable error rule
+(*note Error Recovery::). Otherwise, `yyparse' returns nonzero. We
+have not written any error rules in this example, so any invalid input
+will cause the calculator program to exit. This is not clean behavior
+for a real calculator, but it is adequate for the first example.
+

+
+2.1.6 Running Bison to Make the Parser
+--------------------------------------
+
+Before running Bison to produce a parser, we need to decide how to
+arrange all the source code in one or more source files. For such a
+simple example, the easiest thing is to put everything in one file, the
+grammar file. The definitions of `yylex', `yyerror' and `main' go at
+the end, in the epilogue of the grammar file (*note The Overall Layout
+of a Bison Grammar: Grammar Layout.).
+
+ For a large project, you would probably have several source files,
+and use `make' to arrange to recompile them.
+
+ With all the source in the grammar file, you use the following
+command to convert it into a parser implementation file:
+
+ bison FILE.y
+
+In this example, the grammar file is called `rpcalc.y' (for "Reverse
+Polish CALCulator"). Bison produces a parser implementation file named
+`FILE.tab.c', removing the `.y' from the grammar file name. The parser
+implementation file contains the source code for `yyparse'. The
+additional functions in the grammar file (`yylex', `yyerror' and
+`main') are copied verbatim to the parser implementation file.
+
+\1f
+File: bison.info, Node: Rpcalc Compile, Prev: Rpcalc Generate, Up: RPN Calc
+
+2.1.7 Compiling the Parser Implementation File
+----------------------------------------------
+
+Here is how to compile and run the parser implementation file:
+
+ # List files in current directory.
+ $ ls
+ rpcalc.tab.c rpcalc.y
+
+ # Compile the Bison parser.
+ # `-lm' tells compiler to search math library for `pow'.
+ $ cc -lm -o rpcalc rpcalc.tab.c
+
+ # List files again.
+ $ ls
+ rpcalc rpcalc.tab.c rpcalc.y
+
+ The file `rpcalc' now contains the executable code. Here is an
+example session using `rpcalc'.
+
+ $ rpcalc
+ 4 9 +

+ 3 7 + 3 4 5 *+-

+
+2.2 Infix Notation Calculator: `calc'
+=====================================
+
+We now modify rpcalc to handle infix operators instead of postfix.
+Infix notation involves the concept of operator precedence and the need
+for parentheses nested to arbitrary depth. Here is the Bison code for
+`calc.y', an infix desk-top calculator.
+
+ /* Infix notation calculator. */
+
+ %{
+ #define YYSTYPE double
+ #include <math.h>
+ #include <stdio.h>
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+
+ /* Bison declarations. */
+ %token NUM
+ %left '-' '+'
+ %left '*' '/'
+ %left NEG /* negation--unary minus */
+ %right '^' /* exponentiation */
+
+ %% /* The grammar follows. */
+ input:
+ /* empty */
+ | input line
+ ;
+
+ line:
+ '\n'
+ | exp '\n' { printf ("\t%.10g\n", $1); }
+ ;
+
+ exp:
+ NUM { $$ = $1; }
+ | exp '+' exp { $$ = $1 + $3; }
+ | exp '-' exp { $$ = $1 - $3; }
+ | exp '*' exp { $$ = $1 * $3; }
+ | exp '/' exp { $$ = $1 / $3; }
+ | '-' exp %prec NEG { $$ = -$2; }
+ | exp '^' exp { $$ = pow ($1, $3); }
+ | '(' exp ')' { $$ = $2; }
+ ;
+ %%
+
+The functions `yylex', `yyerror' and `main' can be the same as before.
+
+ There are two important new features shown in this code.
+
+ In the second section (Bison declarations), `%left' declares token
+types and says they are left-associative operators. The declarations
+`%left' and `%right' (right associativity) take the place of `%token'
+which is used to declare a token type name without associativity.
+(These tokens are single-character literals, which ordinarily don't
+need to be declared. We declare them here to specify the
+associativity.)
+
+ Operator precedence is determined by the line ordering of the
+declarations; the higher the line number of the declaration (lower on
+the page or screen), the higher the precedence. Hence, exponentiation
+has the highest precedence, unary minus (`NEG') is next, followed by
+`*' and `/', and so on. *Note Operator Precedence: Precedence.
+
+ The other important new feature is the `%prec' in the grammar
+section for the unary minus operator. The `%prec' simply instructs
+Bison that the rule `| '-' exp' has the same precedence as `NEG'--in
+this case the next-to-highest. *Note Context-Dependent Precedence:
+Contextual Precedence.
+
+ Here is a sample run of `calc.y':
+
+ $ calc
+ 4 + 4.5 - (34/(8*3+-3))
+ 6.880952381
+ -56 + 2

+
+2.3 Simple Error Recovery
+=========================
+
+Up to this point, this manual has not addressed the issue of "error
+recovery"--how to continue parsing after the parser detects a syntax
+error. All we have handled is error reporting with `yyerror'. Recall
+that by default `yyparse' returns after calling `yyerror'. This means
+that an erroneous input line causes the calculator program to exit.
+Now we show how to rectify this deficiency.
+
+ The Bison language itself includes the reserved word `error', which
+may be included in the grammar rules. In the example below it has been
+added to one of the alternatives for `line':
+
+ line:
+ '\n'
+ | exp '\n' { printf ("\t%.10g\n", $1); }
+ | error '\n' { yyerrok; }
+ ;
+
+ This addition to the grammar allows for simple error recovery in the
+event of a syntax error. If an expression that cannot be evaluated is
+read, the error will be recognized by the third rule for `line', and
+parsing will continue. (The `yyerror' function is still called upon to
+print its message as well.) The action executes the statement
+`yyerrok', a macro defined automatically by Bison; its meaning is that
+error recovery is complete (*note Error Recovery::). Note the
+difference between `yyerrok' and `yyerror'; neither one is a misprint.
+
+ This form of error recovery deals with syntax errors. There are
+other kinds of errors; for example, division by zero, which raises an
+exception signal that is normally fatal. A real calculator program
+must handle this signal and use `longjmp' to return to `main' and
+resume parsing input lines; it would also have to discard the rest of
+the current line of input. We won't discuss this issue further because
+it is not specific to Bison programs.
+

+
+2.4 Location Tracking Calculator: `ltcalc'
+==========================================
+
+This example extends the infix notation calculator with location
+tracking. This feature will be used to improve the error messages. For
+the sake of clarity, this example is a simple integer calculator, since
+most of the work needed to use locations will be done in the lexical
+analyzer.

+* Ltcalc Declarations:: Bison and C declarations for ltcalc.
+* Ltcalc Rules:: Grammar rules for ltcalc, with explanations.
+* Ltcalc Lexer:: The lexical analyzer.

+File: bison.info, Node: Ltcalc Declarations, Next: Ltcalc Rules, Up: Location Tracking Calc
+
+2.4.1 Declarations for `ltcalc'
+-------------------------------
+
+The C and Bison declarations for the location tracking calculator are
+the same as the declarations for the infix notation calculator.
+
+ /* Location tracking calculator. */
+
+ %{
+ #define YYSTYPE int
+ #include <math.h>
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+
+ /* Bison declarations. */
+ %token NUM
+
+ %left '-' '+'
+ %left '*' '/'
+ %left NEG
+ %right '^'
+
+ %% /* The grammar follows. */
+
+Note there are no declarations specific to locations. Defining a data
+type for storing locations is not needed: we will use the type provided
+by default (*note Data Types of Locations: Location Type.), which is a
+four member structure with the following integer fields: `first_line',
+`first_column', `last_line' and `last_column'. By conventions, and in
+accordance with the GNU Coding Standards and common practice, the line
+and column count both start at 1.
+

+
+2.4.2 Grammar Rules for `ltcalc'
+--------------------------------
+
+Whether handling locations or not has no effect on the syntax of your
+language. Therefore, grammar rules for this example will be very close
+to those of the previous example: we will only modify them to benefit
+from the new information.
+
+ Here, we will use locations to report divisions by zero, and locate
+the wrong expressions or subexpressions.
+
+ input:
+ /* empty */
+ | input line
+ ;
+
+ line:
+ '\n'
+ | exp '\n' { printf ("%d\n", $1); }
+ ;
+
+ exp:
+ NUM { $$ = $1; }
+ | exp '+' exp { $$ = $1 + $3; }
+ | exp '-' exp { $$ = $1 - $3; }
+ | exp '*' exp { $$ = $1 * $3; }
+ | exp '/' exp
+ {
+ if ($3)
+ $$ = $1 / $3;
+ else
+ {
+ $$ = 1;
+ fprintf (stderr, "%d.%d-%d.%d: division by zero",
+ @3.first_line, @3.first_column,
+ @3.last_line, @3.last_column);
+ }
+ }
+ | '-' exp %prec NEG { $$ = -$2; }
+ | exp '^' exp { $$ = pow ($1, $3); }
+ | '(' exp ')' { $$ = $2; }
+
+ This code shows how to reach locations inside of semantic actions, by
+using the pseudo-variables `@N' for rule components, and the
+pseudo-variable `@$' for groupings.
+
+ We don't need to assign a value to `@$': the output parser does it
+automatically. By default, before executing the C code of each action,
+`@$' is set to range from the beginning of `@1' to the end of `@N', for
+a rule with N components. This behavior can be redefined (*note
+Default Action for Locations: Location Default Action.), and for very
+specific rules, `@$' can be computed by hand.
+

+
+2.4.3 The `ltcalc' Lexical Analyzer.
+------------------------------------
+
+Until now, we relied on Bison's defaults to enable location tracking.
+The next step is to rewrite the lexical analyzer, and make it able to
+feed the parser with the token locations, as it already does for
+semantic values.
+
+ To this end, we must take into account every single character of the
+input text, to avoid the computed locations of being fuzzy or wrong:
+
+ int
+ yylex (void)
+ {
+ int c;
+
+ /* Skip white space. */
+ while ((c = getchar ()) == ' ' || c == '\t')
+ ++yylloc.last_column;
+
+ /* Step. */
+ yylloc.first_line = yylloc.last_line;
+ yylloc.first_column = yylloc.last_column;
+
+ /* Process numbers. */
+ if (isdigit (c))
+ {
+ yylval = c - '0';
+ ++yylloc.last_column;
+ while (isdigit (c = getchar ()))
+ {
+ ++yylloc.last_column;
+ yylval = yylval * 10 + c - '0';
+ }
+ ungetc (c, stdin);
+ return NUM;
+ }
+
+ /* Return end-of-input. */
+ if (c == EOF)
+ return 0;
+
+ /* Return a single char, and update location. */
+ if (c == '\n')
+ {
+ ++yylloc.last_line;
+ yylloc.last_column = 0;
+ }
+ else
+ ++yylloc.last_column;
+ return c;
+ }
+
+ Basically, the lexical analyzer performs the same processing as
+before: it skips blanks and tabs, and reads numbers or single-character
+tokens. In addition, it updates `yylloc', the global variable (of type
+`YYLTYPE') containing the token's location.
+
+ Now, each time this function returns a token, the parser has its
+number as well as its semantic value, and its location in the text.
+The last needed change is to initialize `yylloc', for example in the
+controlling function:
+
+ int
+ main (void)
+ {
+ yylloc.first_line = yylloc.last_line = 1;
+ yylloc.first_column = yylloc.last_column = 0;
+ return yyparse ();
+ }
+
+ Remember that computing locations is not a matter of syntax. Every
+character must be associated to a location update, whether it is in
+valid input, in comments, in literal strings, and so on.

+2.5 Multi-Function Calculator: `mfcalc'
+=======================================
+
+Now that the basics of Bison have been discussed, it is time to move on
+to a more advanced problem. The above calculators provided only five
+functions, `+', `-', `*', `/' and `^'. It would be nice to have a
+calculator that provides other mathematical functions such as `sin',
+`cos', etc.
+
+ It is easy to add new operators to the infix calculator as long as
+they are only single-character literals. The lexical analyzer `yylex'
+passes back all nonnumeric characters as tokens, so new grammar rules
+suffice for adding a new operator. But we want something more
+flexible: built-in functions whose syntax has this form:
+
+ FUNCTION_NAME (ARGUMENT)
+
+At the same time, we will add memory to the calculator, by allowing you
+to create named variables, store values in them, and use them later.
+Here is a sample session with the multi-function calculator:
+
+ $ mfcalc
+ pi = 3.141592653589
+ 3.1415926536
+ sin(pi)
+ 0.0000000000
+ alpha = beta1 = 2.3
+ 2.3000000000
+ alpha
+ 2.3000000000
+ ln(alpha)
+ 0.8329091229
+ exp(ln(beta1))
+ 2.3000000000
+ $
+
+ Note that multiple assignment and nested function calls are
+permitted.

+
+2.5.1 Declarations for `mfcalc'
+-------------------------------
+
+Here are the C and Bison declarations for the multi-function calculator.
+
+ %{
+ #include <math.h> /* For math functions, cos(), sin(), etc. */
+ #include "calc.h" /* Contains definition of `symrec'. */
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+
+ %union {
+ double val; /* For returning numbers. */
+ symrec *tptr; /* For returning symbol-table pointers. */
+ }
+ %token <val> NUM /* Simple double precision number. */
+ %token <tptr> VAR FNCT /* Variable and function. */
+ %type <val> exp
+
+ %right '='
+ %left '-' '+'
+ %left '*' '/'
+ %left NEG /* negation--unary minus */
+ %right '^' /* exponentiation */
+
+ The above grammar introduces only two new features of the Bison
+language. These features allow semantic values to have various data
+types (*note More Than One Value Type: Multiple Types.).
+
+ The `%union' declaration specifies the entire list of possible types;
+this is instead of defining `YYSTYPE'. The allowable types are now
+double-floats (for `exp' and `NUM') and pointers to entries in the
+symbol table. *Note The Collection of Value Types: Union Decl.
+
+ Since values can now have various types, it is necessary to
+associate a type with each grammar symbol whose semantic value is used.
+These symbols are `NUM', `VAR', `FNCT', and `exp'. Their declarations
+are augmented with information about their data type (placed between
+angle brackets).
+
+ The Bison construct `%type' is used for declaring nonterminal
+symbols, just as `%token' is used for declaring token types. We have
+not used `%type' before because nonterminal symbols are normally
+declared implicitly by the rules that define them. But `exp' must be
+declared explicitly so we can specify its value type. *Note
+Nonterminal Symbols: Type Decl.

+
+2.5.3 The `mfcalc' Symbol Table
+-------------------------------
+
+The multi-function calculator requires a symbol table to keep track of
+the names and meanings of variables and functions. This doesn't affect
+the grammar rules (except for the actions) or the Bison declarations,
+but it requires some additional C functions for support.
+
+ The symbol table itself consists of a linked list of records. Its
+definition, which is kept in the header `calc.h', is as follows. It
+provides for either functions or variables to be placed in the table.
+
+ /* Function type. */
+ typedef double (*func_t) (double);
+
+ /* Data type for links in the chain of symbols. */
+ struct symrec
+ {
+ char *name; /* name of symbol */
+ int type; /* type of symbol: either VAR or FNCT */
+ union
+ {
+ double var; /* value of a VAR */
+ func_t fnctptr; /* value of a FNCT */
+ } value;
+ struct symrec *next; /* link field */
+ };
+
+ typedef struct symrec symrec;
+
+ /* The symbol table: a chain of `struct symrec'. */
+ extern symrec *sym_table;
+
+ symrec *putsym (char const *, int);
+ symrec *getsym (char const *);
+
+ The new version of `main' includes a call to `init_table', a
+function that initializes the symbol table. Here it is, and
+`init_table' as well:
+
+ #include <stdio.h>
+
+ /* Called by yyparse on error. */
+ void
+ yyerror (char const *s)
+ {
+ printf ("%s\n", s);
+ }
+
+ struct init
+ {
+ char const *fname;
+ double (*fnct) (double);
+ };
+
+ struct init const arith_fncts[] =
+ {
+ "sin", sin,
+ "cos", cos,
+ "atan", atan,
+ "ln", log,
+ "exp", exp,
+ "sqrt", sqrt,
+ 0, 0
+ };
+
+ /* The symbol table: a chain of `struct symrec'. */
+ symrec *sym_table;
+
+ /* Put arithmetic functions in table. */
+ void
+ init_table (void)
+ {
+ int i;
+ for (i = 0; arith_fncts[i].fname != 0; i++)
+ {
+ symrec *ptr = putsym (arith_fncts[i].fname, FNCT);
+ ptr->value.fnctptr = arith_fncts[i].fnct;
+ }
+ }
+
+ int
+ main (void)
+ {
+ init_table ();
+ return yyparse ();
+ }
+
+ By simply editing the initialization list and adding the necessary
+include files, you can add additional functions to the calculator.
+
+ Two important functions allow look-up and installation of symbols in
+the symbol table. The function `putsym' is passed a name and the type
+(`VAR' or `FNCT') of the object to be installed. The object is linked
+to the front of the list, and a pointer to the object is returned. The
+function `getsym' is passed the name of the symbol to look up. If
+found, a pointer to that symbol is returned; otherwise zero is returned.
+
+ #include <stdlib.h> /* malloc. */
+ #include <string.h> /* strlen. */
+
+ symrec *
+ putsym (char const *sym_name, int sym_type)
+ {
+ symrec *ptr = (symrec *) malloc (sizeof (symrec));
+ ptr->name = (char *) malloc (strlen (sym_name) + 1);
+ strcpy (ptr->name,sym_name);
+ ptr->type = sym_type;
+ ptr->value.var = 0; /* Set value to 0 even if fctn. */
+ ptr->next = (struct symrec *)sym_table;
+ sym_table = ptr;
+ return ptr;
+ }
+
+ symrec *
+ getsym (char const *sym_name)
+ {
+ symrec *ptr;
+ for (ptr = sym_table; ptr != (symrec *) 0;
+ ptr = (symrec *)ptr->next)
+ if (strcmp (ptr->name,sym_name) == 0)
+ return ptr;
+ return 0;
+ }
+
+ The function `yylex' must now recognize variables, numeric values,
+and the single-character arithmetic operators. Strings of alphanumeric
+characters with a leading letter are recognized as either variables or
+functions depending on what the symbol table says about them.
+
+ The string is passed to `getsym' for look up in the symbol table. If
+the name appears in the table, a pointer to its location and its type
+(`VAR' or `FNCT') is returned to `yyparse'. If it is not already in
+the table, then it is installed as a `VAR' using `putsym'. Again, a
+pointer and its type (which must be `VAR') is returned to `yyparse'.
+
+ No change is needed in the handling of numeric values and arithmetic
+operators in `yylex'.
+
+ #include <ctype.h>
+
+ int
+ yylex (void)
+ {
+ int c;

+ s = putsym (symbuf, VAR);
+ yylval.tptr = s;
+ return s->type;
+ }
+
+ /* Any other character is a token by itself. */
+ return c;
+ }
+
+ The error reporting function is unchanged, and the new version of
+`main' includes a call to `init_table' and sets the `yydebug' on user
+demand (*Note Tracing Your Parser: Tracing, for details):
+
+ /* Called by yyparse on error. */
+ void
+ yyerror (char const *s)
+ {
+ fprintf (stderr, "%s\n", s);
+ }

+ int
+ main (int argc, char const* argv[])

+ for (i = 1; i < argc; ++i)
+ if (!strcmp(argv[i], "-p"))
+ yydebug = 1;
+ init_table ();
+ return yyparse ();
+ }
+
+ This program is both powerful and flexible. You may easily add new
+functions, and it is a simple job to modify this code to install
+predefined variables such as `pi' or `e' as well.

+
+\1f
+File: bison.info, Node: Prologue, Next: Prologue Alternatives, Up: Grammar Outline
+
+3.1.1 The prologue
+------------------
+
+The PROLOGUE section contains macro definitions and declarations of
+functions and variables that are used in the actions in the grammar
+rules. These are copied to the beginning of the parser implementation
+file so that they precede the definition of `yyparse'. You can use
+`#include' to get the declarations from a header file. If you don't
+need any C declarations, you may omit the `%{' and `%}' delimiters that
+bracket this section.
+
+ The PROLOGUE section is terminated by the first occurrence of `%}'
+that is outside a comment, a string literal, or a character constant.
+
+ You may have more than one PROLOGUE section, intermixed with the
+BISON DECLARATIONS. This allows you to have C and Bison declarations
+that refer to each other. For example, the `%union' declaration may
+use types defined in a header file, and you may wish to prototype
+functions that take arguments of type `YYSTYPE'. This can be done with
+two PROLOGUE blocks, one before and one after the `%union' declaration.
+
+ %{
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ #include "ptypes.h"
+ %}
+
+ %union {
+ long int n;
+ tree t; /* `tree' is defined in `ptypes.h'. */
+ }
+
+ %{
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ %}
+
+ ...
+
+ When in doubt, it is usually safer to put prologue code before all
+Bison declarations, rather than after. For example, any definitions of
+feature test macros like `_GNU_SOURCE' or `_POSIX_C_SOURCE' should
+appear before all Bison declarations, as feature test macros can affect
+the behavior of Bison-generated `#include' directives.
+
+\1f
+File: bison.info, Node: Prologue Alternatives, Next: Bison Declarations, Prev: Prologue, Up: Grammar Outline
+
+3.1.2 Prologue Alternatives
+---------------------------
+
+The functionality of PROLOGUE sections can often be subtle and
+inflexible. As an alternative, Bison provides a `%code' directive with
+an explicit qualifier field, which identifies the purpose of the code
+and thus the location(s) where Bison should generate it. For C/C++,
+the qualifier can be omitted for the default location, or it can be one
+of `requires', `provides', `top'. *Note %code Summary::.
+
+ Look again at the example of the previous section:
+
+ %{
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ #include "ptypes.h"
+ %}
+
+ %union {
+ long int n;
+ tree t; /* `tree' is defined in `ptypes.h'. */
+ }
+
+ %{
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ %}
+
+ ...
+
+Notice that there are two PROLOGUE sections here, but there's a subtle
+distinction between their functionality. For example, if you decide to
+override Bison's default definition for `YYLTYPE', in which PROLOGUE
+section should you write your new definition? You should write it in
+the first since Bison will insert that code into the parser
+implementation file _before_ the default `YYLTYPE' definition. In
+which PROLOGUE section should you prototype an internal function,
+`trace_token', that accepts `YYLTYPE' and `yytokentype' as arguments?
+You should prototype it in the second since Bison will insert that code
+_after_ the `YYLTYPE' and `yytokentype' definitions.
+
+ This distinction in functionality between the two PROLOGUE sections
+is established by the appearance of the `%union' between them. This
+behavior raises a few questions. First, why should the position of a
+`%union' affect definitions related to `YYLTYPE' and `yytokentype'?
+Second, what if there is no `%union'? In that case, the second kind of
+PROLOGUE section is not available. This behavior is not intuitive.
+
+ To avoid this subtle `%union' dependency, rewrite the example using a
+`%code top' and an unqualified `%code'. Let's go ahead and add the new
+`YYLTYPE' definition and the `trace_token' prototype at the same time:
+
+ %code top {
+ #define _GNU_SOURCE
+ #include <stdio.h>
+
+ /* WARNING: The following code really belongs
+ * in a `%code requires'; see below. */
+
+ #include "ptypes.h"
+ #define YYLTYPE YYLTYPE
+ typedef struct YYLTYPE
+ {
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+ char *filename;
+ } YYLTYPE;
+ }
+
+ %union {
+ long int n;
+ tree t; /* `tree' is defined in `ptypes.h'. */
+ }
+
+ %code {
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ static void trace_token (enum yytokentype token, YYLTYPE loc);
+ }
+
+ ...
+
+In this way, `%code top' and the unqualified `%code' achieve the same
+functionality as the two kinds of PROLOGUE sections, but it's always
+explicit which kind you intend. Moreover, both kinds are always
+available even in the absence of `%union'.
+
+ The `%code top' block above logically contains two parts. The first
+two lines before the warning need to appear near the top of the parser
+implementation file. The first line after the warning is required by
+`YYSTYPE' and thus also needs to appear in the parser implementation
+file. However, if you've instructed Bison to generate a parser header
+file (*note %defines: Decl Summary.), you probably want that line to
+appear before the `YYSTYPE' definition in that header file as well.
+The `YYLTYPE' definition should also appear in the parser header file
+to override the default `YYLTYPE' definition there.
+
+ In other words, in the `%code top' block above, all but the first two
+lines are dependency code required by the `YYSTYPE' and `YYLTYPE'
+definitions. Thus, they belong in one or more `%code requires':
+
+ %code top {
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ }
+
+ %code requires {
+ #include "ptypes.h"
+ }
+ %union {
+ long int n;
+ tree t; /* `tree' is defined in `ptypes.h'. */
+ }
+
+ %code requires {
+ #define YYLTYPE YYLTYPE
+ typedef struct YYLTYPE
+ {
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+ char *filename;
+ } YYLTYPE;
+ }
+
+ %code {
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ static void trace_token (enum yytokentype token, YYLTYPE loc);
+ }
+
+ ...
+
+Now Bison will insert `#include "ptypes.h"' and the new `YYLTYPE'
+definition before the Bison-generated `YYSTYPE' and `YYLTYPE'
+definitions in both the parser implementation file and the parser
+header file. (By the same reasoning, `%code requires' would also be
+the appropriate place to write your own definition for `YYSTYPE'.)
+
+ When you are writing dependency code for `YYSTYPE' and `YYLTYPE',
+you should prefer `%code requires' over `%code top' regardless of
+whether you instruct Bison to generate a parser header file. When you
+are writing code that you need Bison to insert only into the parser
+implementation file and that has no special need to appear at the top
+of that file, you should prefer the unqualified `%code' over `%code
+top'. These practices will make the purpose of each block of your code
+explicit to Bison and to other developers reading your grammar file.
+Following these practices, we expect the unqualified `%code' and `%code
+requires' to be the most important of the four PROLOGUE alternatives.
+
+ At some point while developing your parser, you might decide to
+provide `trace_token' to modules that are external to your parser.
+Thus, you might wish for Bison to insert the prototype into both the
+parser header file and the parser implementation file. Since this
+function is not a dependency required by `YYSTYPE' or `YYLTYPE', it
+doesn't make sense to move its prototype to a `%code requires'. More
+importantly, since it depends upon `YYLTYPE' and `yytokentype', `%code
+requires' is not sufficient. Instead, move its prototype from the
+unqualified `%code' to a `%code provides':
+
+ %code top {
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ }
+
+ %code requires {
+ #include "ptypes.h"
+ }
+ %union {
+ long int n;
+ tree t; /* `tree' is defined in `ptypes.h'. */
+ }
+
+ %code requires {
+ #define YYLTYPE YYLTYPE
+ typedef struct YYLTYPE
+ {
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+ char *filename;
+ } YYLTYPE;
+ }
+
+ %code provides {
+ void trace_token (enum yytokentype token, YYLTYPE loc);
+ }
+
+ %code {
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ }
+
+ ...
+
+Bison will insert the `trace_token' prototype into both the parser
+header file and the parser implementation file after the definitions
+for `yytokentype', `YYLTYPE', and `YYSTYPE'.
+
+ The above examples are careful to write directives in an order that
+reflects the layout of the generated parser implementation and header
+files: `%code top', `%code requires', `%code provides', and then
+`%code'. While your grammar files may generally be easier to read if
+you also follow this order, Bison does not require it. Instead, Bison
+lets you choose an organization that makes sense to you.
+
+ You may declare any of these directives multiple times in the
+grammar file. In that case, Bison concatenates the contained code in
+declaration order. This is the only way in which the position of one
+of these directives within the grammar file affects its functionality.
+
+ The result of the previous two properties is greater flexibility in
+how you may organize your grammar file. For example, you may organize
+semantic-type-related directives by semantic type:
+
+ %code requires { #include "type1.h" }
+ %union { type1 field1; }
+ %destructor { type1_free ($$); } <field1>
+ %printer { type1_print (yyoutput, $$); } <field1>
+
+ %code requires { #include "type2.h" }
+ %union { type2 field2; }
+ %destructor { type2_free ($$); } <field2>
+ %printer { type2_print (yyoutput, $$); } <field2>
+
+You could even place each of the above directive groups in the rules
+section of the grammar file next to the set of rules that uses the
+associated semantic type. (In the rules section, you must terminate
+each of those directives with a semicolon.) And you don't have to
+worry that some directive (like a `%union') in the definitions section
+is going to adversely affect their functionality in some
+counter-intuitive manner just because it comes first. Such an
+organization is not possible using PROLOGUE sections.
+
+ This section has been concerned with explaining the advantages of
+the four PROLOGUE alternatives over the original Yacc PROLOGUE.
+However, in most cases when using these directives, you shouldn't need
+to think about all the low-level ordering issues discussed here.
+Instead, you should simply use these directives to label each block of
+your code according to its purpose and let Bison handle the ordering.
+`%code' is the most generic label. Move code to `%code requires',
+`%code provides', or `%code top' as needed.

+3.1.3 The Bison Declarations Section
+------------------------------------
+

+terminal and nonterminal symbols, specify precedence, and so on. In
+some simple grammars you may not need any declarations. *Note Bison
+Declarations: Declarations.
+

+File: bison.info, Node: Grammar Rules, Next: Epilogue, Prev: Bison Declarations, Up: Grammar Outline
+
+3.1.4 The Grammar Rules Section
+-------------------------------
+
+The "grammar rules" section contains one or more Bison grammar rules,
+and nothing else. *Note Syntax of Grammar Rules: Rules.
+
+ There must always be at least one grammar rule, and the first `%%'
+(which precedes the grammar rules) may never be omitted even if it is
+the first thing in the file.
+

+File: bison.info, Node: Epilogue, Prev: Grammar Rules, Up: Grammar Outline
+
+3.1.5 The epilogue
+------------------
+
+The EPILOGUE is copied verbatim to the end of the parser implementation
+file, just as the PROLOGUE is copied to the beginning. This is the
+most convenient place to put anything that you want to have in the
+parser implementation file but which need not come before the
+definition of `yyparse'. For example, the definitions of `yylex' and
+`yyerror' often go here. Because C requires functions to be declared
+before being used, you often need to declare functions like `yylex' and
+`yyerror' in the Prologue, even if you define them in the Epilogue.
+*Note Parser C-Language Interface: Interface.
+
+ If the last section is empty, you may omit the `%%' that separates it
+from the grammar rules.
+
+ The Bison parser itself contains many macros and identifiers whose
+names start with `yy' or `YY', so it is a good idea to avoid using any
+such names (except those documented in this manual) in the epilogue of
+the grammar file.
+
+\1f
+File: bison.info, Node: Symbols, Next: Rules, Prev: Grammar Outline, Up: Grammar File
+
+3.2 Symbols, Terminal and Nonterminal
+=====================================
+
+"Symbols" in Bison grammars represent the grammatical classifications
+of the language.
+
+ A "terminal symbol" (also known as a "token type") represents a
+class of syntactically equivalent tokens. You use the symbol in grammar
+rules to mean that a token in that class is allowed. The symbol is
+represented in the Bison parser by a numeric code, and the `yylex'
+function returns a token type code to indicate what kind of token has
+been read. You don't need to know what the code value is; you can use
+the symbol to stand for it.
+
+ A "nonterminal symbol" stands for a class of syntactically
+equivalent groupings. The symbol name is used in writing grammar rules.
+By convention, it should be all lower case.
+
+ Symbol names can contain letters, underscores, periods, and
+non-initial digits and dashes. Dashes in symbol names are a GNU
+extension, incompatible with POSIX Yacc. Periods and dashes make
+symbol names less convenient to use with named references, which
+require brackets around such names (*note Named References::).
+Terminal symbols that contain periods or dashes make little sense:
+since they are not valid symbols (in most programming languages) they
+are not exported as token names.
+
+ There are three ways of writing terminal symbols in the grammar:
+
+ * A "named token type" is written with an identifier, like an
+ identifier in C. By convention, it should be all upper case. Each
+ such name must be defined with a Bison declaration such as
+ `%token'. *Note Token Type Names: Token Decl.
+
+ * A "character token type" (or "literal character token") is written
+ in the grammar using the same syntax used in C for character
+ constants; for example, `'+'' is a character token type. A
+ character token type doesn't need to be declared unless you need to
+ specify its semantic value data type (*note Data Types of Semantic
+ Values: Value Type.), associativity, or precedence (*note Operator
+ Precedence: Precedence.).
+
+ By convention, a character token type is used only to represent a
+ token that consists of that particular character. Thus, the token
+ type `'+'' is used to represent the character `+' as a token.
+ Nothing enforces this convention, but if you depart from it, your
+ program will confuse other readers.
+
+ All the usual escape sequences used in character literals in C can
+ be used in Bison as well, but you must not use the null character
+ as a character literal because its numeric code, zero, signifies
+ end-of-input (*note Calling Convention for `yylex': Calling
+ Convention.). Also, unlike standard C, trigraphs have no special
+ meaning in Bison character literals, nor is backslash-newline
+ allowed.
+
+ * A "literal string token" is written like a C string constant; for
+ example, `"<="' is a literal string token. A literal string token
+ doesn't need to be declared unless you need to specify its semantic
+ value data type (*note Value Type::), associativity, or precedence
+ (*note Precedence::).
+
+ You can associate the literal string token with a symbolic name as
+ an alias, using the `%token' declaration (*note Token
+ Declarations: Token Decl.). If you don't do that, the lexical
+ analyzer has to retrieve the token number for the literal string
+ token from the `yytname' table (*note Calling Convention::).
+
+ *Warning*: literal string tokens do not work in Yacc.
+
+ By convention, a literal string token is used only to represent a
+ token that consists of that particular string. Thus, you should
+ use the token type `"<="' to represent the string `<=' as a token.
+ Bison does not enforce this convention, but if you depart from it,
+ people who read your program will be confused.
+
+ All the escape sequences used in string literals in C can be used
+ in Bison as well, except that you must not use a null character
+ within a string literal. Also, unlike Standard C, trigraphs have
+ no special meaning in Bison string literals, nor is
+ backslash-newline allowed. A literal string token must contain
+ two or more characters; for a token containing just one character,
+ use a character token (see above).
+
+ How you choose to write a terminal symbol has no effect on its
+grammatical meaning. That depends only on where it appears in rules and
+on when the parser function returns that symbol.
+
+ The value returned by `yylex' is always one of the terminal symbols,
+except that a zero or negative value signifies end-of-input. Whichever
+way you write the token type in the grammar rules, you write it the
+same way in the definition of `yylex'. The numeric code for a
+character token type is simply the positive numeric code of the
+character, so `yylex' can use the identical value to generate the
+requisite code, though you may need to convert it to `unsigned char' to
+avoid sign-extension on hosts where `char' is signed. Each named token
+type becomes a C macro in the parser implementation file, so `yylex'
+can use the name to stand for the code. (This is why periods don't
+make sense in terminal symbols.) *Note Calling Convention for `yylex':
+Calling Convention.
+
+ If `yylex' is defined in a separate file, you need to arrange for the
+token-type macro definitions to be available there. Use the `-d'
+option when you run Bison, so that it will write these macro definitions
+into a separate header file `NAME.tab.h' which you can include in the
+other source files that need it. *Note Invoking Bison: Invocation.
+
+ If you want to write a grammar that is portable to any Standard C
+host, you must use only nonnull character tokens taken from the basic
+execution character set of Standard C. This set consists of the ten
+digits, the 52 lower- and upper-case English letters, and the
+characters in the following C-language string:
+
+ "\a\b\t\n\v\f\r !\"#%&'()*+,-./:;<=>?[\\]^_{|}~"
+
+ The `yylex' function and Bison must use a consistent character set
+and encoding for character tokens. For example, if you run Bison in an
+ASCII environment, but then compile and run the resulting program in an
+environment that uses an incompatible character set like EBCDIC, the
+resulting program may not work because the tables generated by Bison
+will assume ASCII numeric values for character tokens. It is standard
+practice for software distributions to contain C source files that were
+generated by Bison in an ASCII environment, so installers on platforms
+that are incompatible with ASCII must rebuild those files before
+compiling them.
+
+ The symbol `error' is a terminal symbol reserved for error recovery
+(*note Error Recovery::); you shouldn't use it for any other purpose.
+In particular, `yylex' should never return this value. The default
+value of the error token is 256, unless you explicitly assigned 256 to
+one of your tokens with a `%token' declaration.
+

+
+3.3 Syntax of Grammar Rules
+===========================
+
+A Bison grammar rule has the following general form:
+
+ RESULT: COMPONENTS...;
+
+where RESULT is the nonterminal symbol that this rule describes, and
+COMPONENTS are various terminal and nonterminal symbols that are put
+together by this rule (*note Symbols::).
+
+ For example,
+
+ exp: exp '+' exp;
+
+says that two groupings of type `exp', with a `+' token in between, can
+be combined into a larger grouping of type `exp'.
+
+ White space in rules is significant only to separate symbols. You
+can add extra white space as you wish.
+
+ Scattered among the components can be ACTIONS that determine the
+semantics of the rule. An action looks like this:
+
+ {C STATEMENTS}
+
+This is an example of "braced code", that is, C code surrounded by
+braces, much like a compound statement in C. Braced code can contain
+any sequence of C tokens, so long as its braces are balanced. Bison
+does not check the braced code for correctness directly; it merely
+copies the code to the parser implementation file, where the C compiler
+can check it.
+
+ Within braced code, the balanced-brace count is not affected by
+braces within comments, string literals, or character constants, but it
+is affected by the C digraphs `<%' and `%>' that represent braces. At
+the top level braced code must be terminated by `}' and not by a
+digraph. Bison does not look for trigraphs, so if braced code uses
+trigraphs you should ensure that they do not affect the nesting of
+braces or the boundaries of comments, string literals, or character
+constants.
+
+ Usually there is only one action and it follows the components.
+*Note Actions::.
+
+ Multiple rules for the same RESULT can be written separately or can
+be joined with the vertical-bar character `|' as follows:
+
+ RESULT:
+ RULE1-COMPONENTS...
+ | RULE2-COMPONENTS...
+ ...
+ ;
+
+They are still considered distinct rules even when joined in this way.
+
+ If COMPONENTS in a rule is empty, it means that RESULT can match the
+empty string. For example, here is how to define a comma-separated
+sequence of zero or more `exp' groupings:
+
+ expseq:
+ /* empty */
+ | expseq1
+ ;
+
+ expseq1:
+ exp
+ | expseq1 ',' exp
+ ;
+
+It is customary to write a comment `/* empty */' in each rule with no
+components.

+
+3.4 Recursive Rules
+===================
+
+A rule is called "recursive" when its RESULT nonterminal appears also
+on its right hand side. Nearly all Bison grammars need to use
+recursion, because that is the only way to define a sequence of any
+number of a particular thing. Consider this recursive definition of a
+comma-separated sequence of one or more expressions:
+
+ expseq1:
+ exp
+ | expseq1 ',' exp
+ ;
+
+Since the recursive use of `expseq1' is the leftmost symbol in the
+right hand side, we call this "left recursion". By contrast, here the
+same construct is defined using "right recursion":
+
+ expseq1:
+ exp
+ | exp ',' expseq1
+ ;
+
+Any kind of sequence can be defined using either left recursion or right
+recursion, but you should always use left recursion, because it can
+parse a sequence of any number of elements with bounded stack space.
+Right recursion uses up space on the Bison stack in proportion to the
+number of elements in the sequence, because all the elements must be
+shifted onto the stack before the rule can be applied even once. *Note
+The Bison Parser Algorithm: Algorithm, for further explanation of this.
+
+ "Indirect" or "mutual" recursion occurs when the result of the rule
+does not appear directly on its right hand side, but does appear in
+rules for other nonterminals which do appear on its right hand side.
+
+ For example:
+
+ expr:
+ primary
+ | primary '+' primary
+ ;
+
+ primary:
+ constant
+ | '(' expr ')'
+ ;
+
+defines two mutually-recursive nonterminals, since each refers to the
+other.

+
+3.5 Defining Language Semantics
+===============================
+
+The grammar rules for a language determine only the syntax. The
+semantics are determined by the semantic values associated with various
+tokens and groupings, and by the actions taken when various groupings
+are recognized.
+
+ For example, the calculator calculates properly because the value
+associated with each expression is the proper number; it adds properly
+because the action for the grouping `X + Y' is to add the numbers
+associated with X and Y.
+
+* Menu:
+
+* Value Type:: Specifying one data type for all semantic values.
+* Multiple Types:: Specifying several alternative data types.
+* Actions:: An action is the semantic definition of a grammar rule.
+* Action Types:: Specifying data types for actions to operate on.
+* Mid-Rule Actions:: Most actions go at the end of a rule.
+ This says when, why and how to use the exceptional
+ action in the middle of a rule.
+
+\1f
+File: bison.info, Node: Value Type, Next: Multiple Types, Up: Semantics
+
+3.5.1 Data Types of Semantic Values
+-----------------------------------
+
+In a simple program it may be sufficient to use the same data type for
+the semantic values of all language constructs. This was true in the
+RPN and infix calculator examples (*note Reverse Polish Notation
+Calculator: RPN Calc.).
+
+ Bison normally uses the type `int' for semantic values if your
+program uses the same data type for all language constructs. To
+specify some other type, define `YYSTYPE' as a macro, like this:
+
+ #define YYSTYPE double
+
+`YYSTYPE''s replacement list should be a type name that does not
+contain parentheses or square brackets. This macro definition must go
+in the prologue of the grammar file (*note Outline of a Bison Grammar:
+Grammar Outline.).
+
+\1f
+File: bison.info, Node: Multiple Types, Next: Actions, Prev: Value Type, Up: Semantics
+
+3.5.2 More Than One Value Type
+------------------------------
+
+In most programs, you will need different data types for different kinds
+of tokens and groupings. For example, a numeric constant may need type
+`int' or `long int', while a string constant needs type `char *', and
+an identifier might need a pointer to an entry in the symbol table.
+
+ To use more than one data type for semantic values in one parser,
+Bison requires you to do two things:
+
+ * Specify the entire collection of possible data types, either by
+ using the `%union' Bison declaration (*note The Collection of
+ Value Types: Union Decl.), or by using a `typedef' or a `#define'
+ to define `YYSTYPE' to be a union type whose member names are the
+ type tags.
+
+ * Choose one of those types for each symbol (terminal or
+ nonterminal) for which semantic values are used. This is done for
+ tokens with the `%token' Bison declaration (*note Token Type
+ Names: Token Decl.) and for groupings with the `%type' Bison
+ declaration (*note Nonterminal Symbols: Type Decl.).
+
+\1f
+File: bison.info, Node: Actions, Next: Action Types, Prev: Multiple Types, Up: Semantics
+
+3.5.3 Actions
+-------------
+
+An action accompanies a syntactic rule and contains C code to be
+executed each time an instance of that rule is recognized. The task of
+most actions is to compute a semantic value for the grouping built by
+the rule from the semantic values associated with tokens or smaller
+groupings.
+
+ An action consists of braced code containing C statements, and can be
+placed at any position in the rule; it is executed at that position.
+Most rules have just one action at the end of the rule, following all
+the components. Actions in the middle of a rule are tricky and used
+only for special purposes (*note Actions in Mid-Rule: Mid-Rule
+Actions.).
+
+ The C code in an action can refer to the semantic values of the
+components matched by the rule with the construct `$N', which stands
+for the value of the Nth component. The semantic value for the
+grouping being constructed is `$$'. In addition, the semantic values
+of symbols can be accessed with the named references construct `$NAME'
+or `$[NAME]'. Bison translates both of these constructs into
+expressions of the appropriate type when it copies the actions into the
+parser implementation file. `$$' (or `$NAME', when it stands for the
+current grouping) is translated to a modifiable lvalue, so it can be
+assigned to.
+
+ Here is a typical example:
+
+ exp:
+ ...
+ | exp '+' exp { $$ = $1 + $3; }
+
+ Or, in terms of named references:
+
+ exp[result]:
+ ...
+ | exp[left] '+' exp[right] { $result = $left + $right; }
+
+This rule constructs an `exp' from two smaller `exp' groupings
+connected by a plus-sign token. In the action, `$1' and `$3' (`$left'
+and `$right') refer to the semantic values of the two component `exp'
+groupings, which are the first and third symbols on the right hand side
+of the rule. The sum is stored into `$$' (`$result') so that it
+becomes the semantic value of the addition-expression just recognized
+by the rule. If there were a useful semantic value associated with the
+`+' token, it could be referred to as `$2'.
+
+ *Note Named References::, for more information about using the named
+references construct.
+
+ Note that the vertical-bar character `|' is really a rule separator,
+and actions are attached to a single rule. This is a difference with
+tools like Flex, for which `|' stands for either "or", or "the same
+action as that of the next rule". In the following example, the action
+is triggered only when `b' is found:
+
+ a-or-b: 'a'|'b' { a_or_b_found = 1; };
+
+ If you don't specify an action for a rule, Bison supplies a default:
+`$$ = $1'. Thus, the value of the first symbol in the rule becomes the
+value of the whole rule. Of course, the default action is valid only
+if the two data types match. There is no meaningful default action for
+an empty rule; every empty rule must have an explicit action unless the
+rule's value does not matter.
+
+ `$N' with N zero or negative is allowed for reference to tokens and
+groupings on the stack _before_ those that match the current rule.
+This is a very risky practice, and to use it reliably you must be
+certain of the context in which the rule is applied. Here is a case in
+which you can use this reliably:
+
+ foo:
+ expr bar '+' expr { ... }
+ | expr bar '-' expr { ... }
+ ;
+
+ bar:
+ /* empty */ { previous_expr = $0; }
+ ;
+
+ As long as `bar' is used only in the fashion shown here, `$0' always
+refers to the `expr' which precedes `bar' in the definition of `foo'.
+
+ It is also possible to access the semantic value of the lookahead
+token, if any, from a semantic action. This semantic value is stored
+in `yylval'. *Note Special Features for Use in Actions: Action
+Features.
+
+\1f
+File: bison.info, Node: Action Types, Next: Mid-Rule Actions, Prev: Actions, Up: Semantics
+
+3.5.4 Data Types of Values in Actions
+-------------------------------------
+
+If you have chosen a single data type for semantic values, the `$$' and
+`$N' constructs always have that data type.
+
+ If you have used `%union' to specify a variety of data types, then
+you must declare a choice among these types for each terminal or
+nonterminal symbol that can have a semantic value. Then each time you
+use `$$' or `$N', its data type is determined by which symbol it refers
+to in the rule. In this example,
+
+ exp:
+ ...
+ | exp '+' exp { $$ = $1 + $3; }
+
+`$1' and `$3' refer to instances of `exp', so they all have the data
+type declared for the nonterminal symbol `exp'. If `$2' were used, it
+would have the data type declared for the terminal symbol `'+'',
+whatever that might be.
+
+ Alternatively, you can specify the data type when you refer to the
+value, by inserting `<TYPE>' after the `$' at the beginning of the
+reference. For example, if you have defined types as shown here:
+
+ %union {
+ int itype;
+ double dtype;
+ }
+
+then you can write `$<itype>1' to refer to the first subunit of the
+rule as an integer, or `$<dtype>1' to refer to it as a double.
+
+\1f
+File: bison.info, Node: Mid-Rule Actions, Prev: Action Types, Up: Semantics
+
+3.5.5 Actions in Mid-Rule
+-------------------------
+
+Occasionally it is useful to put an action in the middle of a rule.
+These actions are written just like usual end-of-rule actions, but they
+are executed before the parser even recognizes the following components.
+
+ A mid-rule action may refer to the components preceding it using
+`$N', but it may not refer to subsequent components because it is run
+before they are parsed.
+
+ The mid-rule action itself counts as one of the components of the
+rule. This makes a difference when there is another action later in
+the same rule (and usually there is another at the end): you have to
+count the actions along with the symbols when working out which number
+N to use in `$N'.
+
+ The mid-rule action can also have a semantic value. The action can
+set its value with an assignment to `$$', and actions later in the rule
+can refer to the value using `$N'. Since there is no symbol to name
+the action, there is no way to declare a data type for the value in
+advance, so you must use the `$<...>N' construct to specify a data type
+each time you refer to this value.
+
+ There is no way to set the value of the entire rule with a mid-rule
+action, because assignments to `$$' do not have that effect. The only
+way to set the value for the entire rule is with an ordinary action at
+the end of the rule.
+
+ Here is an example from a hypothetical compiler, handling a `let'
+statement that looks like `let (VARIABLE) STATEMENT' and serves to
+create a variable named VARIABLE temporarily for the duration of
+STATEMENT. To parse this construct, we must put VARIABLE into the
+symbol table while STATEMENT is parsed, then remove it afterward. Here
+is how it is done:
+
+ stmt:
+ LET '(' var ')'
+ { $<context>$ = push_context (); declare_variable ($3); }
+ stmt
+ { $$ = $6; pop_context ($<context>5); }
+
+As soon as `let (VARIABLE)' has been recognized, the first action is
+run. It saves a copy of the current semantic context (the list of
+accessible variables) as its semantic value, using alternative
+`context' in the data-type union. Then it calls `declare_variable' to
+add the new variable to that list. Once the first action is finished,
+the embedded statement `stmt' can be parsed. Note that the mid-rule
+action is component number 5, so the `stmt' is component number 6.
+
+ After the embedded statement is parsed, its semantic value becomes
+the value of the entire `let'-statement. Then the semantic value from
+the earlier action is used to restore the prior list of variables. This
+removes the temporary `let'-variable from the list so that it won't
+appear to exist while the rest of the program is parsed.
+
+ In the above example, if the parser initiates error recovery (*note
+Error Recovery::) while parsing the tokens in the embedded statement
+`stmt', it might discard the previous semantic context `$<context>5'
+without restoring it. Thus, `$<context>5' needs a destructor (*note
+Freeing Discarded Symbols: Destructor Decl.). However, Bison currently
+provides no means to declare a destructor specific to a particular
+mid-rule action's semantic value.
+
+ One solution is to bury the mid-rule action inside a nonterminal
+symbol and to declare a destructor for that symbol:
+
+ %type <context> let
+ %destructor { pop_context ($$); } let
+
+ %%
+
+ stmt:
+ let stmt
+ {
+ $$ = $2;
+ pop_context ($1);
+ };
+
+ let:
+ LET '(' var ')'
+ {
+ $$ = push_context ();
+ declare_variable ($3);
+ };
+
+Note that the action is now at the end of its rule. Any mid-rule
+action can be converted to an end-of-rule action in this way, and this
+is what Bison actually does to implement mid-rule actions.
+
+ Taking action before a rule is completely recognized often leads to
+conflicts since the parser must commit to a parse in order to execute
+the action. For example, the following two rules, without mid-rule
+actions, can coexist in a working parser because the parser can shift
+the open-brace token and look at what follows before deciding whether
+there is a declaration or not:
+
+ compound:
+ '{' declarations statements '}'
+ | '{' statements '}'
+ ;
+
+But when we add a mid-rule action as follows, the rules become
+nonfunctional:
+
+ compound:
+ { prepare_for_local_variables (); }
+ '{' declarations statements '}'
+ | '{' statements '}'
+ ;
+
+Now the parser is forced to decide whether to run the mid-rule action
+when it has read no farther than the open-brace. In other words, it
+must commit to using one rule or the other, without sufficient
+information to do it correctly. (The open-brace token is what is called
+the "lookahead" token at this time, since the parser is still deciding
+what to do about it. *Note Lookahead Tokens: Lookahead.)
+
+ You might think that you could correct the problem by putting
+identical actions into the two rules, like this:
+
+ compound:
+ { prepare_for_local_variables (); }
+ '{' declarations statements '}'
+ | { prepare_for_local_variables (); }
+ '{' statements '}'
+ ;
+
+But this does not help, because Bison does not realize that the two
+actions are identical. (Bison never tries to understand the C code in
+an action.)
+
+ If the grammar is such that a declaration can be distinguished from a
+statement by the first token (which is true in C), then one solution
+which does work is to put the action after the open-brace, like this:
+
+ compound:
+ '{' { prepare_for_local_variables (); }
+ declarations statements '}'
+ | '{' statements '}'
+ ;
+
+Now the first token of the following declaration or statement, which
+would in any case tell Bison which rule to use, can still do so.
+
+ Another solution is to bury the action inside a nonterminal symbol
+which serves as a subroutine:
+
+ subroutine:
+ /* empty */ { prepare_for_local_variables (); }
+ ;
+
+ compound:
+ subroutine '{' declarations statements '}'
+ | subroutine '{' statements '}'
+ ;
+
+Now Bison can execute the action in the rule for `subroutine' without
+deciding which rule for `compound' it will eventually use.

+3.6 Tracking Locations
+======================
+
+Though grammar rules and semantic actions are enough to write a fully
+functional parser, it can be useful to process some additional
+information, especially symbol locations.
+
+ The way locations are handled is defined by providing a data type,
+and actions to take when rules are matched.
+
+* Menu:
+
+* Location Type:: Specifying a data type for locations.
+* Actions and Locations:: Using locations in actions.
+* Location Default Action:: Defining a general way to compute locations.
+
+\1f
+File: bison.info, Node: Location Type, Next: Actions and Locations, Up: Tracking Locations
+
+3.6.1 Data Type of Locations
+----------------------------
+
+Defining a data type for locations is much simpler than for semantic
+values, since all tokens and groupings always use the same type.
+
+ You can specify the type of locations by defining a macro called
+`YYLTYPE', just as you can specify the semantic value type by defining
+a `YYSTYPE' macro (*note Value Type::). When `YYLTYPE' is not defined,
+Bison uses a default structure type with four members:
+
+ typedef struct YYLTYPE
+ {
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+ } YYLTYPE;
+
+ When `YYLTYPE' is not defined, at the beginning of the parsing, Bison
+initializes all these fields to 1 for `yylloc'. To initialize `yylloc'
+with a custom location type (or to chose a different initialization),
+use the `%initial-action' directive. *Note Performing Actions before
+Parsing: Initial Action Decl.
+
+\1f
+File: bison.info, Node: Actions and Locations, Next: Location Default Action, Prev: Location Type, Up: Tracking Locations
+
+3.6.2 Actions and Locations
+---------------------------
+
+Actions are not only useful for defining language semantics, but also
+for describing the behavior of the output parser with locations.
+
+ The most obvious way for building locations of syntactic groupings
+is very similar to the way semantic values are computed. In a given
+rule, several constructs can be used to access the locations of the
+elements being matched. The location of the Nth component of the right
+hand side is `@N', while the location of the left hand side grouping is
+`@$'.
+
+ In addition, the named references construct `@NAME' and `@[NAME]'
+may also be used to address the symbol locations. *Note Named
+References::, for more information about using the named references
+construct.
+
+ Here is a basic example using the default data type for locations:
+
+ exp:
+ ...
+ | exp '/' exp
+ {
+ @$.first_column = @1.first_column;
+ @$.first_line = @1.first_line;
+ @$.last_column = @3.last_column;
+ @$.last_line = @3.last_line;
+ if ($3)
+ $$ = $1 / $3;
+ else
+ {
+ $$ = 1;
+ fprintf (stderr,
+ "Division by zero, l%d,c%d-l%d,c%d",
+ @3.first_line, @3.first_column,
+ @3.last_line, @3.last_column);
+ }
+ }
+
+ As for semantic values, there is a default action for locations that
+is run each time a rule is matched. It sets the beginning of `@$' to
+the beginning of the first symbol, and the end of `@$' to the end of the
+last symbol.
+
+ With this default action, the location tracking can be fully
+automatic. The example above simply rewrites this way:
+
+ exp:
+ ...
+ | exp '/' exp
+ {
+ if ($3)
+ $$ = $1 / $3;
+ else
+ {
+ $$ = 1;
+ fprintf (stderr,
+ "Division by zero, l%d,c%d-l%d,c%d",
+ @3.first_line, @3.first_column,
+ @3.last_line, @3.last_column);
+ }
+ }
+
+ It is also possible to access the location of the lookahead token,
+if any, from a semantic action. This location is stored in `yylloc'.
+*Note Special Features for Use in Actions: Action Features.
+
+\1f
+File: bison.info, Node: Location Default Action, Prev: Actions and Locations, Up: Tracking Locations
+
+3.6.3 Default Action for Locations
+----------------------------------
+
+Actually, actions are not the best place to compute locations. Since
+locations are much more general than semantic values, there is room in
+the output parser to redefine the default action to take for each rule.
+The `YYLLOC_DEFAULT' macro is invoked each time a rule is matched,
+before the associated action is run. It is also invoked while
+processing a syntax error, to compute the error's location. Before
+reporting an unresolvable syntactic ambiguity, a GLR parser invokes
+`YYLLOC_DEFAULT' recursively to compute the location of that ambiguity.
+
+ Most of the time, this macro is general enough to suppress location
+dedicated code from semantic actions.
+
+ The `YYLLOC_DEFAULT' macro takes three parameters. The first one is
+the location of the grouping (the result of the computation). When a
+rule is matched, the second parameter identifies locations of all right
+hand side elements of the rule being matched, and the third parameter
+is the size of the rule's right hand side. When a GLR parser reports
+an ambiguity, which of multiple candidate right hand sides it passes to
+`YYLLOC_DEFAULT' is undefined. When processing a syntax error, the
+second parameter identifies locations of the symbols that were
+discarded during error processing, and the third parameter is the
+number of discarded symbols.
+
+ By default, `YYLLOC_DEFAULT' is defined this way:
+
+ # define YYLLOC_DEFAULT(Cur, Rhs, N) \
+ do \
+ if (N) \
+ { \
+ (Cur).first_line = YYRHSLOC(Rhs, 1).first_line; \
+ (Cur).first_column = YYRHSLOC(Rhs, 1).first_column; \
+ (Cur).last_line = YYRHSLOC(Rhs, N).last_line; \
+ (Cur).last_column = YYRHSLOC(Rhs, N).last_column; \
+ } \
+ else \
+ { \
+ (Cur).first_line = (Cur).last_line = \
+ YYRHSLOC(Rhs, 0).last_line; \
+ (Cur).first_column = (Cur).last_column = \
+ YYRHSLOC(Rhs, 0).last_column; \
+ } \
+ while (0)
+
+where `YYRHSLOC (rhs, k)' is the location of the Kth symbol in RHS when
+K is positive, and the location of the symbol just before the reduction
+when K and N are both zero.
+
+ When defining `YYLLOC_DEFAULT', you should consider that:
+
+ * All arguments are free of side-effects. However, only the first
+ one (the result) should be modified by `YYLLOC_DEFAULT'.
+
+ * For consistency with semantic actions, valid indexes within the
+ right hand side range from 1 to N. When N is zero, only 0 is a
+ valid index, and it refers to the symbol just before the reduction.
+ During error processing N is always positive.
+
+ * Your macro should parenthesize its arguments, if need be, since the
+ actual arguments may not be surrounded by parentheses. Also, your
+ macro should expand to something that can be used as a single
+ statement when it is followed by a semicolon.

+
+3.7 Named References
+====================
+
+As described in the preceding sections, the traditional way to refer to
+any semantic value or location is a "positional reference", which takes
+the form `$N', `$$', `@N', and `@$'. However, such a reference is not
+very descriptive. Moreover, if you later decide to insert or remove
+symbols in the right-hand side of a grammar rule, the need to renumber
+such references can be tedious and error-prone.
+
+ To avoid these issues, you can also refer to a semantic value or
+location using a "named reference". First of all, original symbol
+names may be used as named references. For example:
+
+ invocation: op '(' args ')'
+ { $invocation = new_invocation ($op, $args, @invocation); }
+
+Positional and named references can be mixed arbitrarily. For example:
+
+ invocation: op '(' args ')'
+ { $$ = new_invocation ($op, $args, @$); }
+
+However, sometimes regular symbol names are not sufficient due to
+ambiguities:
+
+ exp: exp '/' exp
+ { $exp = $exp / $exp; } // $exp is ambiguous.
+
+ exp: exp '/' exp
+ { $$ = $1 / $exp; } // One usage is ambiguous.
+
+ exp: exp '/' exp
+ { $$ = $1 / $3; } // No error.
+
+When ambiguity occurs, explicitly declared names may be used for values
+and locations. Explicit names are declared as a bracketed name after a
+symbol appearance in rule definitions. For example:
+ exp[result]: exp[left] '/' exp[right]
+ { $result = $left / $right; }
+
+In order to access a semantic value generated by a mid-rule action, an
+explicit name may also be declared by putting a bracketed name after the
+closing brace of the mid-rule action code:
+ exp[res]: exp[x] '+' {$left = $x;}[left] exp[right]
+ { $res = $left + $right; }
+
+In references, in order to specify names containing dots and dashes, an
+explicit bracketed syntax `$[name]' and `@[name]' must be used:
+ if-stmt: "if" '(' expr ')' "then" then.stmt ';'
+ { $[if-stmt] = new_if_stmt ($expr, $[then.stmt]); }
+
+ It often happens that named references are followed by a dot, dash
+or other C punctuation marks and operators. By default, Bison will read
+`$name.suffix' as a reference to symbol value `$name' followed by
+`.suffix', i.e., an access to the `suffix' field of the semantic value.
+In order to force Bison to recognize `name.suffix' in its entirety as
+the name of a semantic value, the bracketed syntax `$[name.suffix]'
+must be used.
+
+ The named references feature is experimental. More user feedback
+will help to stabilize it.

+The "Bison declarations" section of a Bison grammar defines the symbols
+used in formulating the grammar and the data types of semantic values.

+value (*note More Than One Value Type: Multiple Types.).
+
+ The first rule in the grammar file also specifies the start symbol,
+by default. If you want some other symbol to be the start symbol, you
+must declare it explicitly (*note Languages and Context-Free Grammars:
+Language and Grammar.).

+3.8.1 Require a Version of Bison
+--------------------------------
+
+You may require the minimum version of Bison to process the grammar. If
+the requirement is not met, `bison' exits with an error (exit status
+63).
+
+ %require "VERSION"
+
+\1f
+File: bison.info, Node: Token Decl, Next: Precedence Decl, Prev: Require Decl, Up: Declarations
+
+3.8.2 Token Type Names
+----------------------
+
+The basic way to declare a token type name (terminal symbol) is as
+follows:
+
+ %token NAME
+
+ Bison will convert this into a `#define' directive in the parser, so
+that the function `yylex' (if it is in this file) can use the name NAME
+to stand for this token type's code.
+
+ Alternatively, you can use `%left', `%right', or `%nonassoc' instead
+of `%token', if you wish to specify associativity and precedence.
+*Note Operator Precedence: Precedence Decl.
+
+ You can explicitly specify the numeric code for a token type by
+appending a nonnegative decimal or hexadecimal integer value in the
+field immediately following the token name:
+
+ %token NUM 300
+ %token XNUM 0x12d // a GNU extension
+
+It is generally best, however, to let Bison choose the numeric codes for
+all token types. Bison will automatically select codes that don't
+conflict with each other or with normal characters.
+
+ In the event that the stack type is a union, you must augment the
+`%token' or other token declaration to include the data type
+alternative delimited by angle-brackets (*note More Than One Value
+Type: Multiple Types.).
+
+ For example:
+
+ %union { /* define stack type */
+ double val;
+ symrec *tptr;
+ }
+ %token <val> NUM /* define token NUM and its type */
+
+ You can associate a literal string token with a token type name by
+writing the literal string at the end of a `%token' declaration which
+declares the name. For example:
+
+ %token arrow "=>"
+
+For example, a grammar for the C language might specify these names with
+equivalent literal string tokens:
+
+ %token <operator> OR "||"
+ %token <operator> LE 134 "<="
+ %left OR "<="
+
+Once you equate the literal string and the token name, you can use them
+interchangeably in further declarations or the grammar rules. The
+`yylex' function can use the token name or the literal string to obtain
+the token type code number (*note Calling Convention::). Syntax error
+messages passed to `yyerror' from the parser will reference the literal
+string instead of the token name.
+
+ The token numbered as 0 corresponds to end of file; the following
+line allows for nicer error messages referring to "end of file" instead
+of "$end":
+
+ %token END 0 "end of file"
+
+\1f
+File: bison.info, Node: Precedence Decl, Next: Union Decl, Prev: Token Decl, Up: Declarations
+
+3.8.3 Operator Precedence
+-------------------------
+
+Use the `%left', `%right' or `%nonassoc' declaration to declare a token
+and specify its precedence and associativity, all at once. These are
+called "precedence declarations". *Note Operator Precedence:
+Precedence, for general information on operator precedence.
+
+ The syntax of a precedence declaration is nearly the same as that of
+`%token': either
+
+ %left SYMBOLS...
+
+or
+
+ %left <TYPE> SYMBOLS...
+
+ And indeed any of these declarations serves the purposes of `%token'.
+But in addition, they specify the associativity and relative precedence
+for all the SYMBOLS:
+
+ * The associativity of an operator OP determines how repeated uses
+ of the operator nest: whether `X OP Y OP Z' is parsed by grouping
+ X with Y first or by grouping Y with Z first. `%left' specifies
+ left-associativity (grouping X with Y first) and `%right'
+ specifies right-associativity (grouping Y with Z first).
+ `%nonassoc' specifies no associativity, which means that `X OP Y
+ OP Z' is considered a syntax error.
+
+ * The precedence of an operator determines how it nests with other
+ operators. All the tokens declared in a single precedence
+ declaration have equal precedence and nest together according to
+ their associativity. When two tokens declared in different
+ precedence declarations associate, the one declared later has the
+ higher precedence and is grouped first.
+
+ For backward compatibility, there is a confusing difference between
+the argument lists of `%token' and precedence declarations. Only a
+`%token' can associate a literal string with a token type name. A
+precedence declaration always interprets a literal string as a
+reference to a separate token. For example:
+
+ %left OR "<=" // Does not declare an alias.
+ %left OR 134 "<=" 135 // Declares 134 for OR and 135 for "<=".
+

+File: bison.info, Node: Union Decl, Next: Type Decl, Prev: Precedence Decl, Up: Declarations
+
+3.8.4 The Collection of Value Types
+-----------------------------------
+
+The `%union' declaration specifies the entire collection of possible
+data types for semantic values. The keyword `%union' is followed by
+braced code containing the same thing that goes inside a `union' in C.
+
+ For example:
+
+ %union {
+ double val;
+ symrec *tptr;
+ }
+
+This says that the two alternative types are `double' and `symrec *'.
+They are given names `val' and `tptr'; these names are used in the
+`%token' and `%type' declarations to pick one of the types for a
+terminal or nonterminal symbol (*note Nonterminal Symbols: Type Decl.).
+
+ As an extension to POSIX, a tag is allowed after the `union'. For
+example:
+
+ %union value {
+ double val;
+ symrec *tptr;
+ }
+
+specifies the union tag `value', so the corresponding C type is `union
+value'. If you do not specify a tag, it defaults to `YYSTYPE'.
+
+ As another extension to POSIX, you may specify multiple `%union'
+declarations; their contents are concatenated. However, only the first
+`%union' declaration can specify a tag.
+
+ Note that, unlike making a `union' declaration in C, you need not
+write a semicolon after the closing brace.
+
+ Instead of `%union', you can define and use your own union type
+`YYSTYPE' if your grammar contains at least one `<TYPE>' tag. For
+example, you can put the following into a header file `parser.h':
+
+ union YYSTYPE {
+ double val;
+ symrec *tptr;
+ };
+ typedef union YYSTYPE YYSTYPE;
+
+and then your grammar can use the following instead of `%union':
+
+ %{
+ #include "parser.h"
+ %}
+ %type <val> expr
+ %token <tptr> ID
+
+\1f
+File: bison.info, Node: Type Decl, Next: Initial Action Decl, Prev: Union Decl, Up: Declarations
+
+3.8.5 Nonterminal Symbols
+-------------------------
+
+When you use `%union' to specify multiple value types, you must declare
+the value type of each nonterminal symbol for which values are used.
+This is done with a `%type' declaration, like this:
+
+ %type <TYPE> NONTERMINAL...
+
+Here NONTERMINAL is the name of a nonterminal symbol, and TYPE is the
+name given in the `%union' to the alternative that you want (*note The
+Collection of Value Types: Union Decl.). You can give any number of
+nonterminal symbols in the same `%type' declaration, if they have the
+same value type. Use spaces to separate the symbol names.
+
+ You can also declare the value type of a terminal symbol. To do
+this, use the same `<TYPE>' construction in a declaration for the
+terminal symbol. All kinds of token declarations allow `<TYPE>'.
+
+\1f
+File: bison.info, Node: Initial Action Decl, Next: Destructor Decl, Prev: Type Decl, Up: Declarations
+
+3.8.6 Performing Actions before Parsing
+---------------------------------------
+
+Sometimes your parser needs to perform some initializations before
+parsing. The `%initial-action' directive allows for such arbitrary
+code.
+
+ -- Directive: %initial-action { CODE }
+ Declare that the braced CODE must be invoked before parsing each
+ time `yyparse' is called. The CODE may use `$$' and `@$' --
+ initial value and location of the lookahead -- and the
+ `%parse-param'.
+
+ For instance, if your locations use a file name, you may use
+
+ %parse-param { char const *file_name };
+ %initial-action
+ {
+ @$.initialize (file_name);
+ };
+
+\1f
+File: bison.info, Node: Destructor Decl, Next: Printer Decl, Prev: Initial Action Decl, Up: Declarations
+
+3.8.7 Freeing Discarded Symbols
+-------------------------------
+
+During error recovery (*note Error Recovery::), symbols already pushed
+on the stack and tokens coming from the rest of the file are discarded
+until the parser falls on its feet. If the parser runs out of memory,
+or if it returns via `YYABORT' or `YYACCEPT', all the symbols on the
+stack must be discarded. Even if the parser succeeds, it must discard
+the start symbol.
+
+ When discarded symbols convey heap based information, this memory is
+lost. While this behavior can be tolerable for batch parsers, such as
+in traditional compilers, it is unacceptable for programs like shells or
+protocol implementations that may parse and execute indefinitely.
+
+ The `%destructor' directive defines code that is called when a
+symbol is automatically discarded.
+
+ -- Directive: %destructor { CODE } SYMBOLS
+ Invoke the braced CODE whenever the parser discards one of the
+ SYMBOLS. Within CODE, `$$' designates the semantic value
+ associated with the discarded symbol, and `@$' designates its
+ location. The additional parser parameters are also available
+ (*note The Parser Function `yyparse': Parser Function.).
+
+ When a symbol is listed among SYMBOLS, its `%destructor' is called
+ a per-symbol `%destructor'. You may also define a per-type
+ `%destructor' by listing a semantic type tag among SYMBOLS. In
+ that case, the parser will invoke this CODE whenever it discards
+ any grammar symbol that has that semantic type tag unless that
+ symbol has its own per-symbol `%destructor'.
+
+ Finally, you can define two different kinds of default
+ `%destructor's. (These default forms are experimental. More user
+ feedback will help to determine whether they should become
+ permanent features.) You can place each of `<*>' and `<>' in the
+ SYMBOLS list of exactly one `%destructor' declaration in your
+ grammar file. The parser will invoke the CODE associated with one
+ of these whenever it discards any user-defined grammar symbol that
+ has no per-symbol and no per-type `%destructor'. The parser uses
+ the CODE for `<*>' in the case of such a grammar symbol for which
+ you have formally declared a semantic type tag (`%type' counts as
+ such a declaration, but `$<tag>$' does not). The parser uses the
+ CODE for `<>' in the case of such a grammar symbol that has no
+ declared semantic type tag.
+
+For example:
+
+ %union { char *string; }
+ %token <string> STRING1
+ %token <string> STRING2
+ %type <string> string1
+ %type <string> string2
+ %union { char character; }
+ %token <character> CHR
+ %type <character> chr
+ %token TAGLESS
+
+ %destructor { } <character>
+ %destructor { free ($$); } <*>
+ %destructor { free ($$); printf ("%d", @$.first_line); } STRING1 string1
+ %destructor { printf ("Discarding tagless symbol.\n"); } <>
+
+guarantees that, when the parser discards any user-defined symbol that
+has a semantic type tag other than `<character>', it passes its
+semantic value to `free' by default. However, when the parser discards
+a `STRING1' or a `string1', it also prints its line number to `stdout'.
+It performs only the second `%destructor' in this case, so it invokes
+`free' only once. Finally, the parser merely prints a message whenever
+it discards any symbol, such as `TAGLESS', that has no semantic type
+tag.
+
+ A Bison-generated parser invokes the default `%destructor's only for
+user-defined as opposed to Bison-defined symbols. For example, the
+parser will not invoke either kind of default `%destructor' for the
+special Bison-defined symbols `$accept', `$undefined', or `$end' (*note
+Bison Symbols: Table of Symbols.), none of which you can reference in
+your grammar. It also will not invoke either for the `error' token
+(*note error: Table of Symbols.), which is always defined by Bison
+regardless of whether you reference it in your grammar. However, it
+may invoke one of them for the end token (token 0) if you redefine it
+from `$end' to, for example, `END':
+
+ %token END 0
+
+ Finally, Bison will never invoke a `%destructor' for an unreferenced
+mid-rule semantic value (*note Actions in Mid-Rule: Mid-Rule Actions.).
+That is, Bison does not consider a mid-rule to have a semantic value if
+you do not reference `$$' in the mid-rule's action or `$N' (where N is
+the right-hand side symbol position of the mid-rule) in any later
+action in that rule. However, if you do reference either, the
+Bison-generated parser will invoke the `<>' `%destructor' whenever it
+discards the mid-rule symbol.
+
+
+ "Discarded symbols" are the following:
+
+ * stacked symbols popped during the first phase of error recovery,
+
+ * incoming terminals during the second phase of error recovery,
+
+ * the current lookahead and the entire stack (except the current
+ right-hand side symbols) when the parser returns immediately, and
+
+ * the start symbol, when the parser succeeds.
+
+ The parser can "return immediately" because of an explicit call to
+`YYABORT' or `YYACCEPT', or failed error recovery, or memory exhaustion.
+
+ Right-hand side symbols of a rule that explicitly triggers a syntax
+error via `YYERROR' are not discarded automatically. As a rule of
+thumb, destructors are invoked only when user actions cannot manage the
+memory.
+

+
+3.8.8 Printing Semantic Values
+------------------------------
+
+When run-time traces are enabled (*note Tracing Your Parser: Tracing.),
+the parser reports its actions, such as reductions. When a symbol
+involved in an action is reported, only its kind is displayed, as the
+parser cannot know how semantic values should be formatted.
+
+ The `%printer' directive defines code that is called when a symbol is
+reported. Its syntax is the same as `%destructor' (*note Freeing
+Discarded Symbols: Destructor Decl.).
+
+ -- Directive: %printer { CODE } SYMBOLS
+ Invoke the braced CODE whenever the parser displays one of the
+ SYMBOLS. Within CODE, `yyoutput' denotes the output stream (a
+ `FILE*' in C, and an `std::ostream&' in C++), `$$' designates the
+ semantic value associated with the symbol, and `@$' its location.
+ The additional parser parameters are also available (*note The
+ Parser Function `yyparse': Parser Function.).
+
+ The SYMBOLS are defined as for `%destructor' (*note Freeing
+ Discarded Symbols: Destructor Decl.): they can be per-type (e.g.,
+ `<ival>'), per-symbol (e.g., `exp', `NUM', `"float"'), typed
+ per-default (i.e., `<*>', or untyped per-default (i.e., `<>').
+
+For example:
+
+ %union { char *string; }
+ %token <string> STRING1
+ %token <string> STRING2
+ %type <string> string1
+ %type <string> string2
+ %union { char character; }
+ %token <character> CHR
+ %type <character> chr
+ %token TAGLESS
+
+ %printer { fprintf (yyoutput, "'%c'", $$); } <character>
+ %printer { fprintf (yyoutput, "&%p", $$); } <*>
+ %printer { fprintf (yyoutput, "\"%s\"", $$); } STRING1 string1
+ %printer { fprintf (yyoutput, "<>"); } <>
+
+guarantees that, when the parser print any symbol that has a semantic
+type tag other than `<character>', it display the address of the
+semantic value by default. However, when the parser displays a
+`STRING1' or a `string1', it formats it as a string in double quotes.
+It performs only the second `%printer' in this case, so it prints only
+once. Finally, the parser print `<>' for any symbol, such as `TAGLESS',
+that has no semantic type tag. See also
+

+File: bison.info, Node: Expect Decl, Next: Start Decl, Prev: Printer Decl, Up: Declarations
+
+3.8.9 Suppressing Conflict Warnings
+-----------------------------------
+
+Bison normally warns if there are any conflicts in the grammar (*note
+Shift/Reduce Conflicts: Shift/Reduce.), but most real grammars have
+harmless shift/reduce conflicts which are resolved in a predictable way
+and would be difficult to eliminate. It is desirable to suppress the
+warning about these conflicts unless the number of conflicts changes.
+You can do this with the `%expect' declaration.
+
+ The declaration looks like this:
+
+ %expect N
+
+ Here N is a decimal integer. The declaration says there should be N
+shift/reduce conflicts and no reduce/reduce conflicts. Bison reports
+an error if the number of shift/reduce conflicts differs from N, or if
+there are any reduce/reduce conflicts.
+
+ For deterministic parsers, reduce/reduce conflicts are more serious,
+and should be eliminated entirely. Bison will always report
+reduce/reduce conflicts for these parsers. With GLR parsers, however,
+both kinds of conflicts are routine; otherwise, there would be no need
+to use GLR parsing. Therefore, it is also possible to specify an
+expected number of reduce/reduce conflicts in GLR parsers, using the
+declaration:
+
+ %expect-rr N
+
+ In general, using `%expect' involves these steps:
+
+ * Compile your grammar without `%expect'. Use the `-v' option to
+ get a verbose list of where the conflicts occur. Bison will also
+ print the number of conflicts.
+
+ * Check each of the conflicts to make sure that Bison's default
+ resolution is what you really want. If not, rewrite the grammar
+ and go back to the beginning.
+
+ * Add an `%expect' declaration, copying the number N from the number
+ which Bison printed. With GLR parsers, add an `%expect-rr'
+ declaration as well.
+
+ Now Bison will report an error if you introduce an unexpected
+conflict, but will keep silent otherwise.

+
+3.8.10 The Start-Symbol
+-----------------------
+
+Bison assumes by default that the start symbol for the grammar is the
+first nonterminal specified in the grammar specification section. The
+programmer may override this restriction with the `%start' declaration
+as follows:
+
+ %start SYMBOL
+
+\1f
+File: bison.info, Node: Pure Decl, Next: Push Decl, Prev: Start Decl, Up: Declarations
+
+3.8.11 A Pure (Reentrant) Parser
+--------------------------------
+
+A "reentrant" program is one which does not alter in the course of
+execution; in other words, it consists entirely of "pure" (read-only)
+code. Reentrancy is important whenever asynchronous execution is
+possible; for example, a nonreentrant program may not be safe to call
+from a signal handler. In systems with multiple threads of control, a
+nonreentrant program must be called only within interlocks.
+
+ Normally, Bison generates a parser which is not reentrant. This is
+suitable for most uses, and it permits compatibility with Yacc. (The
+standard Yacc interfaces are inherently nonreentrant, because they use
+statically allocated variables for communication with `yylex',
+including `yylval' and `yylloc'.)
+
+ Alternatively, you can generate a pure, reentrant parser. The Bison
+declaration `%define api.pure' says that you want the parser to be
+reentrant. It looks like this:
+
+ %define api.pure
+
+ The result is that the communication variables `yylval' and `yylloc'
+become local variables in `yyparse', and a different calling convention
+is used for the lexical analyzer function `yylex'. *Note Calling
+Conventions for Pure Parsers: Pure Calling, for the details of this.
+The variable `yynerrs' becomes local in `yyparse' in pull mode but it
+becomes a member of yypstate in push mode. (*note The Error Reporting
+Function `yyerror': Error Reporting.). The convention for calling
+`yyparse' itself is unchanged.
+
+ Whether the parser is pure has nothing to do with the grammar rules.
+You can generate either a pure parser or a nonreentrant parser from any
+valid grammar.
+

+
+3.8.12 A Push Parser
+--------------------
+
+(The current push parsing interface is experimental and may evolve.
+More user feedback will help to stabilize it.)
+
+ A pull parser is called once and it takes control until all its input
+is completely parsed. A push parser, on the other hand, is called each
+time a new token is made available.
+
+ A push parser is typically useful when the parser is part of a main
+event loop in the client's application. This is typically a
+requirement of a GUI, when the main event loop needs to be triggered
+within a certain time period.
+
+ Normally, Bison generates a pull parser. The following Bison
+declaration says that you want the parser to be a push parser (*note
+api.push-pull: %define Summary.):
+
+ %define api.push-pull push
+
+ In almost all cases, you want to ensure that your push parser is also
+a pure parser (*note A Pure (Reentrant) Parser: Pure Decl.). The only
+time you should create an impure push parser is to have backwards
+compatibility with the impure Yacc pull mode interface. Unless you know
+what you are doing, your declarations should look like this:
+
+ %define api.pure
+ %define api.push-pull push
+
+ There is a major notable functional difference between the pure push
+parser and the impure push parser. It is acceptable for a pure push
+parser to have many parser instances, of the same type of parser, in
+memory at the same time. An impure push parser should only use one
+parser at a time.
+
+ When a push parser is selected, Bison will generate some new symbols
+in the generated parser. `yypstate' is a structure that the generated
+parser uses to store the parser's state. `yypstate_new' is the
+function that will create a new parser instance. `yypstate_delete'
+will free the resources associated with the corresponding parser
+instance. Finally, `yypush_parse' is the function that should be
+called whenever a token is available to provide the parser. A trivial
+example of using a pure push parser would look like this:
+
+ int status;
+ yypstate *ps = yypstate_new ();
+ do {
+ status = yypush_parse (ps, yylex (), NULL);
+ } while (status == YYPUSH_MORE);
+ yypstate_delete (ps);
+
+ If the user decided to use an impure push parser, a few things about
+the generated parser will change. The `yychar' variable becomes a
+global variable instead of a variable in the `yypush_parse' function.
+For this reason, the signature of the `yypush_parse' function is
+changed to remove the token as a parameter. A nonreentrant push parser
+example would thus look like this:
+
+ extern int yychar;
+ int status;
+ yypstate *ps = yypstate_new ();
+ do {
+ yychar = yylex ();
+ status = yypush_parse (ps);
+ } while (status == YYPUSH_MORE);
+ yypstate_delete (ps);
+
+ That's it. Notice the next token is put into the global variable
+`yychar' for use by the next invocation of the `yypush_parse' function.
+
+ Bison also supports both the push parser interface along with the
+pull parser interface in the same generated parser. In order to get
+this functionality, you should replace the `%define api.push-pull push'
+declaration with the `%define api.push-pull both' declaration. Doing
+this will create all of the symbols mentioned earlier along with the
+two extra symbols, `yyparse' and `yypull_parse'. `yyparse' can be used
+exactly as it normally would be used. However, the user should note
+that it is implemented in the generated parser by calling
+`yypull_parse'. This makes the `yyparse' function that is generated
+with the `%define api.push-pull both' declaration slower than the normal
+`yyparse' function. If the user calls the `yypull_parse' function it
+will parse the rest of the input stream. It is possible to
+`yypush_parse' tokens to select a subgrammar and then `yypull_parse'
+the rest of the input stream. If you would like to switch back and
+forth between between parsing styles, you would have to write your own
+`yypull_parse' function that knows when to quit looking for input. An
+example of using the `yypull_parse' function would look like this:
+
+ yypstate *ps = yypstate_new ();
+ yypull_parse (ps); /* Will call the lexer */
+ yypstate_delete (ps);
+
+ Adding the `%define api.pure' declaration does exactly the same
+thing to the generated parser with `%define api.push-pull both' as it
+did for `%define api.push-pull push'.

+3.8.13 Bison Declaration Summary
+--------------------------------
+
+Here is a summary of the declarations used to define a grammar:
+
+ -- Directive: %union
+ Declare the collection of data types that semantic values may have
+ (*note The Collection of Value Types: Union Decl.).
+
+ -- Directive: %token
+ Declare a terminal symbol (token type name) with no precedence or
+ associativity specified (*note Token Type Names: Token Decl.).
+
+ -- Directive: %right
+ Declare a terminal symbol (token type name) that is
+ right-associative (*note Operator Precedence: Precedence Decl.).
+
+ -- Directive: %left
+ Declare a terminal symbol (token type name) that is
+ left-associative (*note Operator Precedence: Precedence Decl.).
+
+ -- Directive: %nonassoc
+ Declare a terminal symbol (token type name) that is nonassociative
+ (*note Operator Precedence: Precedence Decl.). Using it in a way
+ that would be associative is a syntax error.
+
+ -- Directive: %type
+ Declare the type of semantic values for a nonterminal symbol
+ (*note Nonterminal Symbols: Type Decl.).
+
+ -- Directive: %start
+ Specify the grammar's start symbol (*note The Start-Symbol: Start
+ Decl.).
+
+ -- Directive: %expect
+ Declare the expected number of shift-reduce conflicts (*note
+ Suppressing Conflict Warnings: Expect Decl.).
+
+
+In order to change the behavior of `bison', use the following
+directives:
+
+ -- Directive: %code {CODE}
+ -- Directive: %code QUALIFIER {CODE}
+ Insert CODE verbatim into the output parser source at the default
+ location or at the location specified by QUALIFIER. *Note %code
+ Summary::.
+
+ -- Directive: %debug
+ In the parser implementation file, define the macro `YYDEBUG' (or
+ `PREFIXDEBUG' with `%define api.prefix PREFIX'), see *note
+ Multiple Parsers in the Same Program: Multiple Parsers.) to 1 if
+ it is not already defined, so that the debugging facilities are
+ compiled. *Note Tracing Your Parser: Tracing.
+
+ -- Directive: %define VARIABLE
+ -- Directive: %define VARIABLE VALUE
+ -- Directive: %define VARIABLE "VALUE"
+ Define a variable to adjust Bison's behavior. *Note %define
+ Summary::.
+
+ -- Directive: %defines
+ Write a parser header file containing macro definitions for the
+ token type names defined in the grammar as well as a few other
+ declarations. If the parser implementation file is named `NAME.c'
+ then the parser header file is named `NAME.h'.
+
+ For C parsers, the parser header file declares `YYSTYPE' unless
+ `YYSTYPE' is already defined as a macro or you have used a
+ `<TYPE>' tag without using `%union'. Therefore, if you are using
+ a `%union' (*note More Than One Value Type: Multiple Types.) with
+ components that require other definitions, or if you have defined
+ a `YYSTYPE' macro or type definition (*note Data Types of Semantic
+ Values: Value Type.), you need to arrange for these definitions to
+ be propagated to all modules, e.g., by putting them in a
+ prerequisite header that is included both by your parser and by any
+ other module that needs `YYSTYPE'.
+
+ Unless your parser is pure, the parser header file declares
+ `yylval' as an external variable. *Note A Pure (Reentrant)
+ Parser: Pure Decl.
+
+ If you have also used locations, the parser header file declares
+ `YYLTYPE' and `yylloc' using a protocol similar to that of the
+ `YYSTYPE' macro and `yylval'. *Note Tracking Locations::.
+
+ This parser header file is normally essential if you wish to put
+ the definition of `yylex' in a separate source file, because
+ `yylex' typically needs to be able to refer to the above-mentioned
+ declarations and to the token type codes. *Note Semantic Values
+ of Tokens: Token Values.
+
+ If you have declared `%code requires' or `%code provides', the
+ output header also contains their code. *Note %code Summary::.
+
+ -- Directive: %defines DEFINES-FILE
+ Same as above, but save in the file DEFINES-FILE.
+
+ -- Directive: %destructor
+ Specify how the parser should reclaim the memory associated to
+ discarded symbols. *Note Freeing Discarded Symbols: Destructor
+ Decl.
+
+ -- Directive: %file-prefix "PREFIX"
+ Specify a prefix to use for all Bison output file names. The names
+ are chosen as if the grammar file were named `PREFIX.y'.
+
+ -- Directive: %language "LANGUAGE"
+ Specify the programming language for the generated parser.
+ Currently supported languages include C, C++, and Java. LANGUAGE
+ is case-insensitive.
+
+ This directive is experimental and its effect may be modified in
+ future releases.
+
+ -- Directive: %locations
+ Generate the code processing the locations (*note Special Features
+ for Use in Actions: Action Features.). This mode is enabled as
+ soon as the grammar uses the special `@N' tokens, but if your
+ grammar does not use it, using `%locations' allows for more
+ accurate syntax error messages.
+
+ -- Directive: %no-lines
+ Don't generate any `#line' preprocessor commands in the parser
+ implementation file. Ordinarily Bison writes these commands in the
+ parser implementation file so that the C compiler and debuggers
+ will associate errors and object code with your source file (the
+ grammar file). This directive causes them to associate errors
+ with the parser implementation file, treating it as an independent
+ source file in its own right.
+
+ -- Directive: %output "FILE"
+ Specify FILE for the parser implementation file.
+
+ -- Directive: %pure-parser
+ Deprecated version of `%define api.pure' (*note api.pure: %define
+ Summary.), for which Bison is more careful to warn about
+ unreasonable usage.
+
+ -- Directive: %require "VERSION"
+ Require version VERSION or higher of Bison. *Note Require a
+ Version of Bison: Require Decl.
+
+ -- Directive: %skeleton "FILE"
+ Specify the skeleton to use.
+
+ If FILE does not contain a `/', FILE is the name of a skeleton
+ file in the Bison installation directory. If it does, FILE is an
+ absolute file name or a file name relative to the directory of the
+ grammar file. This is similar to how most shells resolve commands.
+
+ -- Directive: %token-table
+ Generate an array of token names in the parser implementation file.
+ The name of the array is `yytname'; `yytname[I]' is the name of
+ the token whose internal Bison token code number is I. The first
+ three elements of `yytname' correspond to the predefined tokens
+ `"$end"', `"error"', and `"$undefined"'; after these come the
+ symbols defined in the grammar file.
+
+ The name in the table includes all the characters needed to
+ represent the token in Bison. For single-character literals and
+ literal strings, this includes the surrounding quoting characters
+ and any escape sequences. For example, the Bison single-character
+ literal `'+'' corresponds to a three-character name, represented
+ in C as `"'+'"'; and the Bison two-character literal string `"\\/"'
+ corresponds to a five-character name, represented in C as
+ `"\"\\\\/\""'.
+
+ When you specify `%token-table', Bison also generates macro
+ definitions for macros `YYNTOKENS', `YYNNTS', and `YYNRULES', and
+ `YYNSTATES':
+
+ `YYNTOKENS'
+ The highest token number, plus one.
+
+ `YYNNTS'
+ The number of nonterminal symbols.
+
+ `YYNRULES'
+ The number of grammar rules,
+
+ `YYNSTATES'
+ The number of parser states (*note Parser States::).
+
+ -- Directive: %verbose
+ Write an extra output file containing verbose descriptions of the
+ parser states and what is done for each type of lookahead token in
+ that state. *Note Understanding Your Parser: Understanding, for
+ more information.
+
+ -- Directive: %yacc
+ Pretend the option `--yacc' was given, i.e., imitate Yacc,
+ including its naming conventions. *Note Bison Options::, for more.

+3.8.14 %define Summary
+----------------------
+
+There are many features of Bison's behavior that can be controlled by
+assigning the feature a single value. For historical reasons, some
+such features are assigned values by dedicated directives, such as
+`%start', which assigns the start symbol. However, newer such features
+are associated with variables, which are assigned by the `%define'
+directive:
+
+ -- Directive: %define VARIABLE
+ -- Directive: %define VARIABLE VALUE
+ -- Directive: %define VARIABLE "VALUE"
+ Define VARIABLE to VALUE.
+
+ VALUE must be placed in quotation marks if it contains any
+ character other than a letter, underscore, period, or non-initial
+ dash or digit. Omitting `"VALUE"' entirely is always equivalent
+ to specifying `""'.
+
+ It is an error if a VARIABLE is defined by `%define' multiple
+ times, but see *note -D NAME[=VALUE]: Bison Options.
+
+ The rest of this section summarizes variables and values that
+`%define' accepts.
+
+ Some VARIABLEs take Boolean values. In this case, Bison will
+complain if the variable definition does not meet one of the following
+four conditions:
+
+ 1. `VALUE' is `true'
+
+ 2. `VALUE' is omitted (or `""' is specified). This is equivalent to
+ `true'.
+
+ 3. `VALUE' is `false'.
+
+ 4. VARIABLE is never defined. In this case, Bison selects a default
+ value.
+
+ What VARIABLEs are accepted, as well as their meanings and default
+values, depend on the selected target language and/or the parser
+skeleton (*note %language: Decl Summary, *note %skeleton: Decl
+Summary.). Unaccepted VARIABLEs produce an error. Some of the
+accepted VARIABLEs are:
+
+ * `api.prefix'
+
+ * Language(s): All
+
+ * Purpose: Rename exported symbols *Note Multiple Parsers in
+ the Same Program: Multiple Parsers.
+
+ * Accepted Values: String
+
+ * Default Value: `yy'

+ * History: introduced in Bison 2.6

+ will help to stabilize it.)

+ * Accepted Values: `pull', `push', `both'
+
+ * Default Value: `pull'
+
+ * `lr.default-reductions'
+
+ * Language(s): all
+
+ * Purpose: Specify the kind of states that are permitted to

+
+ * `most' otherwise.

+ * Purpose: Request that Bison allow unreachable parser states to
+ remain in the parser tables. *Note Unreachable States::.
+
+ * Accepted Values: Boolean
+
+ * Default Value: `false'
+
+ * `lr.type'
+
+ * Language(s): all
+
+ * Purpose: Specify the type of parser tables within the LR(1)
+ family. *Note LR Table Construction::. (This feature is
+ experimental. More user feedback will help to stabilize it.)
+
+ * Accepted Values: `lalr', `ielr', `canonical-lr'
+
+ * Default Value: `lalr'
+
+ * `namespace'
+
+ * Languages(s): C++
+
+ * Purpose: Specify the namespace for the parser class. For
+ example, if you specify:
+
+ %define namespace "foo::bar"
+
+ Bison uses `foo::bar' verbatim in references such as:
+
+ foo::bar::parser::semantic_type
+
+ However, to open a namespace, Bison removes any leading `::'
+ and then splits on any remaining occurrences:
+
+ namespace foo { namespace bar {
+ class position;
+ class location;
+ } }
+
+ * Accepted Values: Any absolute or relative C++ namespace
+ reference without a trailing `"::"'. For example, `"foo"' or
+ `"::foo::bar"'.
+
+ * Default Value: The value specified by `%name-prefix', which
+ defaults to `yy'. This usage of `%name-prefix' is for
+ backward compatibility and can be confusing since
+ `%name-prefix' also specifies the textual prefix for the
+ lexical analyzer function. Thus, if you specify
+ `%name-prefix', it is best to also specify `%define
+ namespace' so that `%name-prefix' _only_ affects the lexical
+ analyzer function. For example, if you specify:
+
+ %define namespace "foo"
+ %name-prefix "bar::"
+
+ The parser namespace is `foo' and `yylex' is referenced as
+ `bar::lex'.
+
+ * `parse.lac'
+
+ * Languages(s): C (deterministic parsers only)
+
+ * Purpose: Enable LAC (lookahead correction) to improve syntax
+ error handling. *Note LAC::.
+
+ * Accepted Values: `none', `full'

+3.8.15 %code Summary
+--------------------
+
+The `%code' directive inserts code verbatim into the output parser
+source at any of a predefined set of locations. It thus serves as a
+flexible and user-friendly alternative to the traditional Yacc
+prologue, `%{CODE%}'. This section summarizes the functionality of
+`%code' for the various target languages supported by Bison. For a
+detailed discussion of how to use `%code' in place of `%{CODE%}' for
+C/C++ and why it is advantageous to do so, *note Prologue
+Alternatives::.
+
+ -- Directive: %code {CODE}
+ This is the unqualified form of the `%code' directive. It inserts
+ CODE verbatim at a language-dependent default location in the
+ parser implementation.
+
+ For C/C++, the default location is the parser implementation file
+ after the usual contents of the parser header file. Thus, the
+ unqualified form replaces `%{CODE%}' for most purposes.
+
+ For Java, the default location is inside the parser class.
+
+ -- Directive: %code QUALIFIER {CODE}
+ This is the qualified form of the `%code' directive. QUALIFIER
+ identifies the purpose of CODE and thus the location(s) where
+ Bison should insert it. That is, if you need to specify
+ location-sensitive CODE that does not belong at the default
+ location selected by the unqualified `%code' form, use this form
+ instead.
+
+ For any particular qualifier or for the unqualified form, if there
+are multiple occurrences of the `%code' directive, Bison concatenates
+the specified code in the order in which it appears in the grammar file.
+
+ Not all qualifiers are accepted for all target languages. Unaccepted
+qualifiers produce an error. Some of the accepted qualifiers are:
+
+ * requires
+
+ * Language(s): C, C++
+
+ * Purpose: This is the best place to write dependency code
+ required for `YYSTYPE' and `YYLTYPE'. In other words, it's
+ the best place to define types referenced in `%union'
+ directives, and it's the best place to override Bison's
+ default `YYSTYPE' and `YYLTYPE' definitions.
+
+ * Location(s): The parser header file and the parser
+ implementation file before the Bison-generated `YYSTYPE' and
+ `YYLTYPE' definitions.
+
+ * provides
+
+ * Language(s): C, C++
+
+ * Purpose: This is the best place to write additional
+ definitions and declarations that should be provided to other
+ modules.
+
+ * Location(s): The parser header file and the parser
+ implementation file after the Bison-generated `YYSTYPE',
+ `YYLTYPE', and token definitions.
+
+ * top
+
+ * Language(s): C, C++
+
+ * Purpose: The unqualified `%code' or `%code requires' should
+ usually be more appropriate than `%code top'. However,
+ occasionally it is necessary to insert code much nearer the
+ top of the parser implementation file. For example:
+
+ %code top {
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ }
+
+ * Location(s): Near the top of the parser implementation file.
+
+ * imports
+
+ * Language(s): Java
+
+ * Purpose: This is the best place to write Java import
+ directives.
+
+ * Location(s): The parser Java file after any Java package
+ directive and before any class definitions.
+
+ Though we say the insertion locations are language-dependent, they
+are technically skeleton-dependent. Writers of non-standard skeletons
+however should choose their locations consistently with the behavior of
+the standard Bison skeletons.

+
+3.9 Multiple Parsers in the Same Program
+========================================
+
+Most programs that use Bison parse only one language and therefore
+contain only one Bison parser. But what if you want to parse more than
+one language with the same program? Then you need to avoid name
+conflicts between different definitions of functions and variables such
+as `yyparse', `yylval'. To use different parsers from the same
+compilation unit, you also need to avoid conflicts on types and macros
+(e.g., `YYSTYPE') exported in the generated header.
+
+ The easy way to do this is to define the `%define' variable
+`api.prefix'. With different `api.prefix's it is guaranteed that
+headers do not conflict when included together, and that compiled
+objects can be linked together too. Specifying `%define api.prefix
+PREFIX' (or passing the option `-Dapi.prefix=PREFIX', see *note
+Invoking Bison: Invocation.) renames the interface functions and
+variables of the Bison parser to start with PREFIX instead of `yy', and
+all the macros to start by PREFIX (i.e., PREFIX upper-cased) instead of
+`YY'.
+
+ The renamed symbols include `yyparse', `yylex', `yyerror',
+`yynerrs', `yylval', `yylloc', `yychar' and `yydebug'. If you use a
+push parser, `yypush_parse', `yypull_parse', `yypstate', `yypstate_new'
+and `yypstate_delete' will also be renamed. The renamed macros include
+`YYSTYPE', `YYLTYPE', and `YYDEBUG', which is treated specifically --
+more about this below.
+
+ For example, if you use `%define api.prefix c', the names become
+`cparse', `clex', ..., `CSTYPE', `CLTYPE', and so on.
+
+ The `%define' variable `api.prefix' works in two different ways. In
+the implementation file, it works by adding macro definitions to the
+beginning of the parser implementation file, defining `yyparse' as
+`PREFIXparse', and so on:
+
+ #define YYSTYPE CTYPE
+ #define yyparse cparse
+ #define yylval clval
+ ...
+ YYSTYPE yylval;
+ int yyparse (void);
+
+ This effectively substitutes one name for the other in the entire
+parser implementation file, thus the "original" names (`yylex',
+`YYSTYPE', ...) are also usable in the parser implementation file.
+
+ However, in the parser header file, the symbols are defined renamed,
+for instance:
+
+ extern CSTYPE clval;
+ int cparse (void);
+
+ The macro `YYDEBUG' is commonly used to enable the tracing support in
+parsers. To comply with this tradition, when `api.prefix' is used,
+`YYDEBUG' (not renamed) is used as a default value:
+
+ /* Enabling traces. */
+ #ifndef CDEBUG
+ # if defined YYDEBUG
+ # if YYDEBUG
+ # define CDEBUG 1
+ # else
+ # define CDEBUG 0
+ # endif
+ # else
+ # define CDEBUG 0
+ # endif
+ #endif
+ #if CDEBUG
+ extern int cdebug;
+ #endif
+
+
+
+ Prior to Bison 2.6, a feature similar to `api.prefix' was provided by
+the obsolete directive `%name-prefix' (*note Bison Symbols: Table of
+Symbols.) and the option `--name-prefix' (*note Bison Options::).

+
+The Bison parser is actually a C function named `yyparse'. Here we
+describe the interface conventions of `yyparse' and the other functions
+that it needs to use.
+
+ Keep in mind that the parser uses many C identifiers starting with
+`yy' and `YY' for internal purposes. If you use such an identifier
+(aside from those in this manual) in an action or in epilogue in the
+grammar file, you are likely to run into trouble.

+File: bison.info, Node: Parser Function, Next: Push Parser Function, Up: Interface
+
+4.1 The Parser Function `yyparse'
+=================================
+
+You call the function `yyparse' to cause parsing to occur. This
+function reads tokens, executes actions, and ultimately returns when it
+encounters end-of-input or an unrecoverable syntax error. You can also
+write an action which directs `yyparse' to return immediately without
+reading further.
+
+ -- Function: int yyparse (void)
+ The value returned by `yyparse' is 0 if parsing was successful
+ (return is due to end-of-input).
+
+ The value is 1 if parsing failed because of invalid input, i.e.,
+ input that contains a syntax error or that causes `YYABORT' to be
+ invoked.
+
+ The value is 2 if parsing failed due to memory exhaustion.
+
+ In an action, you can cause immediate return from `yyparse' by using
+these macros:
+
+ -- Macro: YYACCEPT
+ Return immediately with value 0 (to report success).
+
+ -- Macro: YYABORT
+ Return immediately with value 1 (to report failure).
+
+ If you use a reentrant parser, you can optionally pass additional
+parameter information to it in a reentrant way. To do so, use the
+declaration `%parse-param':
+
+ -- Directive: %parse-param {ARGUMENT-DECLARATION}
+ Declare that an argument declared by the braced-code
+ ARGUMENT-DECLARATION is an additional `yyparse' argument. The
+ ARGUMENT-DECLARATION is used when declaring functions or
+ prototypes. The last identifier in ARGUMENT-DECLARATION must be
+ the argument name.
+
+ Here's an example. Write this in the parser:
+
+ %parse-param {int *nastiness}
+ %parse-param {int *randomness}
+
+Then call the parser like this:
+
+ {
+ int nastiness, randomness;
+ ... /* Store proper data in `nastiness' and `randomness'. */
+ value = yyparse (&nastiness, &randomness);
+ ...
+ }
+
+In the grammar actions, use expressions like this to refer to the data:
+
+ exp: ... { ...; *randomness += 1; ... }

+
+ -- Function: yypstate* yypstate_new (void)

+
+4.6 The Lexical Analyzer Function `yylex'
+=========================================
+
+The "lexical analyzer" function, `yylex', recognizes tokens from the
+input stream and returns them to the parser. Bison does not create
+this function automatically; you must write it so that `yyparse' can
+call it. The function is sometimes referred to as a lexical scanner.
+
+ In simple programs, `yylex' is often defined at the end of the Bison
+grammar file. If `yylex' is defined in a separate source file, you
+need to arrange for the token-type macro definitions to be available
+there. To do this, use the `-d' option when you run Bison, so that it
+will write these macro definitions into the separate parser header
+file, `NAME.tab.h', which you can include in the other source files
+that need it. *Note Invoking Bison: Invocation.
+
+* Menu:
+
+* Calling Convention:: How `yyparse' calls `yylex'.
+* Token Values:: How `yylex' must return the semantic value
+ of the token it has read.
+* Token Locations:: How `yylex' must return the text location
+ (line number, etc.) of the token, if the
+ actions want that.
+* Pure Calling:: How the calling convention differs in a pure parser
+ (*note A Pure (Reentrant) Parser: Pure Decl.).
+
+\1f
+File: bison.info, Node: Calling Convention, Next: Token Values, Up: Lexical
+
+4.6.1 Calling Convention for `yylex'
+------------------------------------
+
+The value that `yylex' returns must be the positive numeric code for
+the type of token it has just found; a zero or negative value signifies
+end-of-input.
+
+ When a token is referred to in the grammar rules by a name, that name
+in the parser implementation file becomes a C macro whose definition is
+the proper numeric code for that token type. So `yylex' can use the
+name to indicate that type. *Note Symbols::.
+
+ When a token is referred to in the grammar rules by a character
+literal, the numeric code for that character is also the code for the
+token type. So `yylex' can simply return that character code, possibly
+converted to `unsigned char' to avoid sign-extension. The null
+character must not be used this way, because its code is zero and that
+signifies end-of-input.
+
+ Here is an example showing these things:
+
+ int
+ yylex (void)
+ {
+ ...
+ if (c == EOF) /* Detect end-of-input. */
+ return 0;
+ ...
+ if (c == '+' || c == '-')
+ return c; /* Assume token type for `+' is '+'. */
+ ...
+ return INT; /* Return the type of the token. */
+ ...
+ }
+
+This interface has been designed so that the output from the `lex'
+utility can be used without change as the definition of `yylex'.
+
+ If the grammar uses literal string tokens, there are two ways that
+`yylex' can determine the token type codes for them:
+
+ * If the grammar defines symbolic token names as aliases for the
+ literal string tokens, `yylex' can use these symbolic names like
+ all others. In this case, the use of the literal string tokens in
+ the grammar file has no effect on `yylex'.
+
+ * `yylex' can find the multicharacter token in the `yytname' table.
+ The index of the token in the table is the token type's code. The
+ name of a multicharacter token is recorded in `yytname' with a
+ double-quote, the token's characters, and another double-quote.
+ The token's characters are escaped as necessary to be suitable as
+ input to Bison.
+
+ Here's code for looking up a multicharacter token in `yytname',
+ assuming that the characters of the token are stored in
+ `token_buffer', and assuming that the token does not contain any
+ characters like `"' that require escaping.
+
+ for (i = 0; i < YYNTOKENS; i++)
+ {
+ if (yytname[i] != 0
+ && yytname[i][0] == '"'

+
+4.6.2 Semantic Values of Tokens
+-------------------------------
+
+In an ordinary (nonreentrant) parser, the semantic value of the token
+must be stored into the global variable `yylval'. When you are using
+just one data type for semantic values, `yylval' has that type. Thus,
+if the type is `int' (the default), you might write this in `yylex':
+
+ ...
+ yylval = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ ...
+
+ When you are using multiple data types, `yylval''s type is a union
+made from the `%union' declaration (*note The Collection of Value
+Types: Union Decl.). So when you store a token's value, you must use
+the proper member of the union. If the `%union' declaration looks like
+this:
+
+ %union {
+ int intval;
+ double val;
+ symrec *tptr;
+ }
+
+then the code in `yylex' might look like this:
+
+ ...
+ yylval.intval = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ ...
+

+
+4.6.3 Textual Locations of Tokens
+---------------------------------
+
+If you are using the `@N'-feature (*note Tracking Locations::) in
+actions to keep track of the textual locations of tokens and groupings,
+then you must provide this information in `yylex'. The function
+`yyparse' expects to find the textual location of a token just parsed
+in the global variable `yylloc'. So `yylex' must store the proper data
+in that variable.
+
+ By default, the value of `yylloc' is a structure and you need only
+initialize the members that are going to be used by the actions. The
+four members are called `first_line', `first_column', `last_line' and
+`last_column'. Note that the use of this feature makes the parser
+noticeably slower.
+
+ The data type of `yylloc' has the name `YYLTYPE'.

+
+4.6.4 Calling Conventions for Pure Parsers
+------------------------------------------
+
+When you use the Bison declaration `%define api.pure' to request a
+pure, reentrant parser, the global communication variables `yylval' and
+`yylloc' cannot be used. (*Note A Pure (Reentrant) Parser: Pure Decl.)
+In such parsers the two global variables are replaced by pointers
+passed as arguments to `yylex'. You must declare them as shown here,
+and pass the information back by storing it through those pointers.
+
+ int
+ yylex (YYSTYPE *lvalp, YYLTYPE *llocp)
+ {
+ ...
+ *lvalp = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ ...
+ }
+
+ If the grammar file does not use the `@' constructs to refer to
+textual locations, then the type `YYLTYPE' will not be defined. In
+this case, omit the second argument; `yylex' will be called with only
+one argument.
+
+ If you wish to pass the additional parameter data to `yylex', use
+`%lex-param' just like `%parse-param' (*note Parser Function::).
+
+ -- Directive: lex-param {ARGUMENT-DECLARATION}
+ Declare that the braced-code ARGUMENT-DECLARATION is an additional
+ `yylex' argument declaration.
+
+ For instance:
+
+ %parse-param {int *nastiness}
+ %lex-param {int *nastiness}
+ %parse-param {int *randomness}
+
+results in the following signatures:
+
+ int yylex (int *nastiness);
+ int yyparse (int *nastiness, int *randomness);
+
+ If `%define api.pure' is added:
+
+ int yylex (YYSTYPE *lvalp, int *nastiness);
+ int yyparse (int *nastiness, int *randomness);
+
+and finally, if both `%define api.pure' and `%locations' are used:
+
+ int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness);
+ int yyparse (int *nastiness, int *randomness);

+File: bison.info, Node: Error Reporting, Next: Action Features, Prev: Lexical, Up: Interface
+
+4.7 The Error Reporting Function `yyerror'
+==========================================
+
+The Bison parser detects a "syntax error" or "parse error" whenever it
+reads a token which cannot satisfy any syntax rule. An action in the
+grammar can also explicitly proclaim an error, using the macro
+`YYERROR' (*note Special Features for Use in Actions: Action Features.).
+
+ The Bison parser expects to report the error by calling an error
+reporting function named `yyerror', which you must supply. It is
+called by `yyparse' whenever a syntax error is found, and it receives
+one argument. For a syntax error, the string is normally
+`"syntax error"'.
+
+ If you invoke the directive `%error-verbose' in the Bison
+declarations section (*note The Bison Declarations Section: Bison
+Declarations.), then Bison provides a more verbose and specific error
+message string instead of just plain `"syntax error"'. However, that
+message sometimes contains incorrect information if LAC is not enabled
+(*note LAC::).
+
+ The parser can detect one other kind of error: memory exhaustion.
+This can happen when the input contains constructions that are very
+deeply nested. It isn't likely you will encounter this, since the Bison
+parser normally extends its stack automatically up to a very large
+limit. But if memory is exhausted, `yyparse' calls `yyerror' in the
+usual fashion, except that the argument string is `"memory exhausted"'.
+
+ In some cases diagnostics like `"syntax error"' are translated
+automatically from English to some other language before they are
+passed to `yyerror'. *Note Internationalization::.
+
+ The following definition suffices in simple programs:
+
+ void
+ yyerror (char const *s)
+ {
+ fprintf (stderr, "%s\n", s);
+ }
+
+ After `yyerror' returns to `yyparse', the latter will attempt error
+recovery if you have written suitable error recovery grammar rules
+(*note Error Recovery::). If recovery is impossible, `yyparse' will
+immediately return 1.
+
+ Obviously, in location tracking pure parsers, `yyerror' should have
+an access to the current location. This is indeed the case for the GLR
+parsers, but not for the Yacc parser, for historical reasons. I.e., if
+`%locations %define api.pure' is passed then the prototypes for
+`yyerror' are:
+
+ void yyerror (char const *msg); /* Yacc parsers. */
+ void yyerror (YYLTYPE *locp, char const *msg); /* GLR parsers. */
+
+ If `%parse-param {int *nastiness}' is used, then:
+
+ void yyerror (int *nastiness, char const *msg); /* Yacc parsers. */
+ void yyerror (int *nastiness, char const *msg); /* GLR parsers. */
+
+ Finally, GLR and Yacc parsers share the same `yyerror' calling
+convention for absolutely pure parsers, i.e., when the calling
+convention of `yylex' _and_ the calling convention of `%define
+api.pure' are pure. I.e.:
+
+ /* Location tracking. */
+ %locations
+ /* Pure yylex. */
+ %define api.pure
+ %lex-param {int *nastiness}
+ /* Pure yyparse. */
+ %parse-param {int *nastiness}
+ %parse-param {int *randomness}
+
+results in the following signatures for all the parser kinds:
+
+ int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness);
+ int yyparse (int *nastiness, int *randomness);
+ void yyerror (YYLTYPE *locp,
+ int *nastiness, int *randomness,
+ char const *msg);
+
+The prototypes are only indications of how the code produced by Bison
+uses `yyerror'. Bison-generated code always ignores the returned
+value, so `yyerror' can return any type, including `void'. Also,
+`yyerror' can be a variadic function; that is why the message is always
+passed last.
+
+ Traditionally `yyerror' returns an `int' that is always ignored, but
+this is purely for historical reasons, and `void' is preferable since
+it more accurately describes the return type for `yyerror'.
+
+ The variable `yynerrs' contains the number of syntax errors reported
+so far. Normally this variable is global; but if you request a pure
+parser (*note A Pure (Reentrant) Parser: Pure Decl.) then it is a
+local variable which only the actions can access.

+
+4.8 Special Features for Use in Actions
+=======================================
+
+Here is a table of Bison constructs, variables and macros that are
+useful in actions.
+
+ -- Variable: $$
+ Acts like a variable that contains the semantic value for the
+ grouping made by the current rule. *Note Actions::.
+
+ -- Variable: $N
+ Acts like a variable that contains the semantic value for the Nth
+ component of the current rule. *Note Actions::.
+
+ -- Variable: $<TYPEALT>$
+ Like `$$' but specifies alternative TYPEALT in the union specified
+ by the `%union' declaration. *Note Data Types of Values in
+ Actions: Action Types.
+
+ -- Variable: $<TYPEALT>N
+ Like `$N' but specifies alternative TYPEALT in the union specified
+ by the `%union' declaration. *Note Data Types of Values in
+ Actions: Action Types.
+
+ -- Macro: YYABORT `;'
+ Return immediately from `yyparse', indicating failure. *Note The
+ Parser Function `yyparse': Parser Function.
+
+ -- Macro: YYACCEPT `;'
+ Return immediately from `yyparse', indicating success. *Note The
+ Parser Function `yyparse': Parser Function.
+
+ -- Macro: YYBACKUP (TOKEN, VALUE)`;'
+ Unshift a token. This macro is allowed only for rules that reduce
+ a single value, and only when there is no lookahead token. It is
+ also disallowed in GLR parsers. It installs a lookahead token
+ with token type TOKEN and semantic value VALUE; then it discards
+ the value that was going to be reduced by this rule.
+
+ If the macro is used when it is not valid, such as when there is a
+ lookahead token already, then it reports a syntax error with a
+ message `cannot back up' and performs ordinary error recovery.
+
+ In either case, the rest of the action is not executed.
+
+ -- Macro: YYEMPTY
+ Value stored in `yychar' when there is no lookahead token.
+
+ -- Macro: YYEOF
+ Value stored in `yychar' when the lookahead is the end of the input
+ stream.
+
+ -- Macro: YYERROR `;'
+ Cause an immediate syntax error. This statement initiates error
+ recovery just as if the parser itself had detected an error;
+ however, it does not call `yyerror', and does not print any
+ message. If you want to print an error message, call `yyerror'
+ explicitly before the `YYERROR;' statement. *Note Error
+ Recovery::.
+
+ -- Macro: YYRECOVERING
+ The expression `YYRECOVERING ()' yields 1 when the parser is
+ recovering from a syntax error, and 0 otherwise. *Note Error
+ Recovery::.
+
+ -- Variable: yychar
+ Variable containing either the lookahead token, or `YYEOF' when the
+ lookahead is the end of the input stream, or `YYEMPTY' when no
+ lookahead has been performed so the next token is not yet known.
+ Do not modify `yychar' in a deferred semantic action (*note GLR
+ Semantic Actions::). *Note Lookahead Tokens: Lookahead.
+
+ -- Macro: yyclearin `;'
+ Discard the current lookahead token. This is useful primarily in
+ error rules. Do not invoke `yyclearin' in a deferred semantic
+ action (*note GLR Semantic Actions::). *Note Error Recovery::.
+
+ -- Macro: yyerrok `;'
+ Resume generating error messages immediately for subsequent syntax
+ errors. This is useful primarily in error rules. *Note Error
+ Recovery::.
+
+ -- Variable: yylloc
+ Variable containing the lookahead token location when `yychar' is
+ not set to `YYEMPTY' or `YYEOF'. Do not modify `yylloc' in a
+ deferred semantic action (*note GLR Semantic Actions::). *Note
+ Actions and Locations: Actions and Locations.
+
+ -- Variable: yylval
+ Variable containing the lookahead token semantic value when
+ `yychar' is not set to `YYEMPTY' or `YYEOF'. Do not modify
+ `yylval' in a deferred semantic action (*note GLR Semantic
+ Actions::). *Note Actions: Actions.
+
+ -- Value: @$
+ Acts like a structure variable containing information on the
+ textual location of the grouping made by the current rule. *Note
+ Tracking Locations::.
+
+
+ -- Value: @N
+ Acts like a structure variable containing information on the
+ textual location of the Nth component of the current rule. *Note

+
+4.9 Parser Internationalization
+===============================
+
+A Bison-generated parser can print diagnostics, including error and
+tracing messages. By default, they appear in English. However, Bison
+also supports outputting diagnostics in the user's native language. To
+make this work, the user should set the usual environment variables.
+*Note The User's View: (gettext)Users. For example, the shell command
+`export LC_ALL=fr_CA.UTF-8' might set the user's locale to French
+Canadian using the UTF-8 encoding. The exact set of available locales
+depends on the user's installation.
+
+ The maintainer of a package that uses a Bison-generated parser
+enables the internationalization of the parser's output through the
+following steps. Here we assume a package that uses GNU Autoconf and
+GNU Automake.
+
+ 1. Into the directory containing the GNU Autoconf macros used by the
+ package--often called `m4'--copy the `bison-i18n.m4' file
+ installed by Bison under `share/aclocal/bison-i18n.m4' in Bison's
+ installation directory. For example:
+
+ cp /usr/local/share/aclocal/bison-i18n.m4 m4/bison-i18n.m4
+
+ 2. In the top-level `configure.ac', after the `AM_GNU_GETTEXT'
+ invocation, add an invocation of `BISON_I18N'. This macro is
+ defined in the file `bison-i18n.m4' that you copied earlier. It
+ causes `configure' to find the value of the `BISON_LOCALEDIR'
+ variable, and it defines the source-language symbol `YYENABLE_NLS'
+ to enable translations in the Bison-generated parser.
+
+ 3. In the `main' function of your program, designate the directory
+ containing Bison's runtime message catalog, through a call to
+ `bindtextdomain' with domain name `bison-runtime'. For example:
+
+ bindtextdomain ("bison-runtime", BISON_LOCALEDIR);
+
+ Typically this appears after any other call `bindtextdomain
+ (PACKAGE, LOCALEDIR)' that your package already has. Here we rely
+ on `BISON_LOCALEDIR' to be defined as a string through the
+ `Makefile'.
+
+ 4. In the `Makefile.am' that controls the compilation of the `main'
+ function, make `BISON_LOCALEDIR' available as a C preprocessor
+ macro, either in `DEFS' or in `AM_CPPFLAGS'. For example:
+
+ DEFS = @DEFS@ -DBISON_LOCALEDIR='"$(BISON_LOCALEDIR)"'
+
+ or:
+
+ AM_CPPFLAGS = -DBISON_LOCALEDIR='"$(BISON_LOCALEDIR)"'
+
+ 5. Finally, invoke the command `autoreconf' to generate the build
+ infrastructure.

+
+5 The Bison Parser Algorithm
+****************************
+
+As Bison reads tokens, it pushes them onto a stack along with their
+semantic values. The stack is called the "parser stack". Pushing a
+token is traditionally called "shifting".
+
+ For example, suppose the infix calculator has read `1 + 5 *', with a
+`3' to come. The stack will have four elements, one for each token
+that was shifted.
+
+ But the stack does not always have an element for each token read.
+When the last N tokens and groupings shifted match the components of a
+grammar rule, they can be combined according to that rule. This is
+called "reduction". Those tokens and groupings are replaced on the
+stack by a single grouping whose symbol is the result (left hand side)
+of that rule. Running the rule's action is part of the process of
+reduction, because this is what computes the semantic value of the
+resulting grouping.
+
+ For example, if the infix calculator's parser stack contains this:
+
+ 1 + 5 * 3
+
+and the next input token is a newline character, then the last three
+elements can be reduced to 15 via the rule:
+
+ expr: expr '*' expr;
+
+Then the stack contains just these three elements:
+
+ 1 + 15
+
+At this point, another reduction can be made, resulting in the single
+value 16. Then the newline token can be shifted.
+
+ The parser tries, by shifts and reductions, to reduce the entire
+input down to a single grouping whose symbol is the grammar's
+start-symbol (*note Languages and Context-Free Grammars: Language and
+Grammar.).
+
+ This kind of parser is known in the literature as a bottom-up parser.

+
+5.1 Lookahead Tokens
+====================
+
+The Bison parser does _not_ always reduce immediately as soon as the
+last N tokens and groupings match a rule. This is because such a
+simple strategy is inadequate to handle most languages. Instead, when a
+reduction is possible, the parser sometimes "looks ahead" at the next
+token in order to decide what to do.
+
+ When a token is read, it is not immediately shifted; first it
+becomes the "lookahead token", which is not on the stack. Now the
+parser can perform one or more reductions of tokens and groupings on
+the stack, while the lookahead token remains off to the side. When no
+more reductions should take place, the lookahead token is shifted onto
+the stack. This does not mean that all possible reductions have been
+done; depending on the token type of the lookahead token, some rules
+may choose to delay their application.
+
+ Here is a simple case where lookahead is needed. These three rules
+define expressions which contain binary addition operators and postfix
+unary factorial operators (`!'), and allow parentheses for grouping.
+
+ expr:
+ term '+' expr
+ | term
+ ;
+
+ term:
+ '(' expr ')'
+ | term '!'
+ | NUMBER
+ ;
+
+ Suppose that the tokens `1 + 2' have been read and shifted; what
+should be done? If the following token is `)', then the first three
+tokens must be reduced to form an `expr'. This is the only valid
+course, because shifting the `)' would produce a sequence of symbols
+`term ')'', and no rule allows this.
+
+ If the following token is `!', then it must be shifted immediately so
+that `2 !' can be reduced to make a `term'. If instead the parser were
+to reduce before shifting, `1 + 2' would become an `expr'. It would
+then be impossible to shift the `!' because doing so would produce on
+the stack the sequence of symbols `expr '!''. No rule allows that
+sequence.
+
+ The lookahead token is stored in the variable `yychar'. Its
+semantic value and location, if any, are stored in the variables
+`yylval' and `yylloc'. *Note Special Features for Use in Actions:
+Action Features.
+
+\1f
+File: bison.info, Node: Shift/Reduce, Next: Precedence, Prev: Lookahead, Up: Algorithm
+
+5.2 Shift/Reduce Conflicts
+==========================
+
+Suppose we are parsing a language which has if-then and if-then-else
+statements, with a pair of rules like this:
+
+ if_stmt:
+ IF expr THEN stmt
+ | IF expr THEN stmt ELSE stmt
+ ;
+
+Here we assume that `IF', `THEN' and `ELSE' are terminal symbols for
+specific keyword tokens.
+
+ When the `ELSE' token is read and becomes the lookahead token, the
+contents of the stack (assuming the input is valid) are just right for
+reduction by the first rule. But it is also legitimate to shift the
+`ELSE', because that would lead to eventual reduction by the second
+rule.
+
+ This situation, where either a shift or a reduction would be valid,
+is called a "shift/reduce conflict". Bison is designed to resolve
+these conflicts by choosing to shift, unless otherwise directed by
+operator precedence declarations. To see the reason for this, let's
+contrast it with the other alternative.
+
+ Since the parser prefers to shift the `ELSE', the result is to attach
+the else-clause to the innermost if-statement, making these two inputs
+equivalent:
+
+ if x then if y then win (); else lose;
+
+ if x then do; if y then win (); else lose; end;
+
+ But if the parser chose to reduce when possible rather than shift,
+the result would be to attach the else-clause to the outermost
+if-statement, making these two inputs equivalent:
+
+ if x then if y then win (); else lose;
+
+ if x then do; if y then win (); end; else lose;
+
+ The conflict exists because the grammar as written is ambiguous:
+either parsing of the simple nested if-statement is legitimate. The
+established convention is that these ambiguities are resolved by
+attaching the else-clause to the innermost if-statement; this is what
+Bison accomplishes by choosing to shift rather than reduce. (It would
+ideally be cleaner to write an unambiguous grammar, but that is very
+hard to do in this case.) This particular ambiguity was first
+encountered in the specifications of Algol 60 and is called the
+"dangling `else'" ambiguity.
+
+ To avoid warnings from Bison about predictable, legitimate
+shift/reduce conflicts, use the `%expect N' declaration. There will be
+no warning as long as the number of shift/reduce conflicts is exactly
+N, and Bison will report an error if there is a different number.
+*Note Suppressing Conflict Warnings: Expect Decl.
+
+ The definition of `if_stmt' above is solely to blame for the
+conflict, but the conflict does not actually appear without additional
+rules. Here is a complete Bison grammar file that actually manifests
+the conflict:
+
+ %token IF THEN ELSE variable
+ %%
+ stmt:
+ expr
+ | if_stmt
+ ;
+
+ if_stmt:
+ IF expr THEN stmt
+ | IF expr THEN stmt ELSE stmt
+ ;
+
+ expr:
+ variable

+5.3 Operator Precedence
+=======================
+
+Another situation where shift/reduce conflicts appear is in arithmetic
+expressions. Here shifting is not always the preferred resolution; the
+Bison declarations for operator precedence allow you to specify when to
+shift and when to reduce.

+
+\1f
+File: bison.info, Node: Why Precedence, Next: Using Precedence, Up: Precedence
+
+5.3.1 When Precedence is Needed
+-------------------------------
+
+Consider the following ambiguous grammar fragment (ambiguous because the
+input `1 - 2 * 3' can be parsed in two different ways):
+
+ expr:
+ expr '-' expr
+ | expr '*' expr
+ | expr '<' expr
+ | '(' expr ')'
+ ...
+ ;
+
+Suppose the parser has seen the tokens `1', `-' and `2'; should it
+reduce them via the rule for the subtraction operator? It depends on
+the next token. Of course, if the next token is `)', we must reduce;
+shifting is invalid because no single rule can reduce the token
+sequence `- 2 )' or anything starting with that. But if the next token
+is `*' or `<', we have a choice: either shifting or reduction would
+allow the parse to complete, but with different results.
+
+ To decide which one Bison should do, we must consider the results.
+If the next operator token OP is shifted, then it must be reduced first
+in order to permit another opportunity to reduce the difference. The
+result is (in effect) `1 - (2 OP 3)'. On the other hand, if the
+subtraction is reduced before shifting OP, the result is
+`(1 - 2) OP 3'. Clearly, then, the choice of shift or reduce should
+depend on the relative precedence of the operators `-' and OP: `*'
+should be shifted first, but not `<'.
+
+ What about input such as `1 - 2 - 5'; should this be `(1 - 2) - 5'
+or should it be `1 - (2 - 5)'? For most operators we prefer the
+former, which is called "left association". The latter alternative,
+"right association", is desirable for assignment operators. The choice
+of left or right association is a matter of whether the parser chooses
+to shift or reduce when the stack contains `1 - 2' and the lookahead
+token is `-': shifting makes right-associativity.
+

+File: bison.info, Node: Using Precedence, Next: Precedence Examples, Prev: Why Precedence, Up: Precedence
+
+5.3.2 Specifying Operator Precedence
+------------------------------------
+
+Bison allows you to specify these choices with the operator precedence
+declarations `%left' and `%right'. Each such declaration contains a
+list of tokens, which are operators whose precedence and associativity
+is being declared. The `%left' declaration makes all those operators
+left-associative and the `%right' declaration makes them
+right-associative. A third alternative is `%nonassoc', which declares
+that it is a syntax error to find the same operator twice "in a row".
+
+ The relative precedence of different operators is controlled by the
+order in which they are declared. The first `%left' or `%right'
+declaration in the file declares the operators whose precedence is
+lowest, the next such declaration declares the operators whose
+precedence is a little higher, and so on.
+
+\1f
+File: bison.info, Node: Precedence Examples, Next: How Precedence, Prev: Using Precedence, Up: Precedence
+
+5.3.3 Precedence Examples
+-------------------------
+
+In our example, we would want the following declarations:
+
+ %left '<'
+ %left '-'
+ %left '*'
+
+ In a more complete example, which supports other operators as well,
+we would declare them in groups of equal precedence. For example,
+`'+'' is declared with `'-'':
+
+ %left '<' '>' '=' NE LE GE
+ %left '+' '-'
+ %left '*' '/'
+
+(Here `NE' and so on stand for the operators for "not equal" and so on.
+We assume that these tokens are more than one character long and
+therefore are represented by names, not character literals.)
+
+\1f
+File: bison.info, Node: How Precedence, Prev: Precedence Examples, Up: Precedence
+
+5.3.4 How Precedence Works
+--------------------------
+
+The first effect of the precedence declarations is to assign precedence
+levels to the terminal symbols declared. The second effect is to assign
+precedence levels to certain rules: each rule gets its precedence from
+the last terminal symbol mentioned in the components. (You can also
+specify explicitly the precedence of a rule. *Note Context-Dependent
+Precedence: Contextual Precedence.)
+
+ Finally, the resolution of conflicts works by comparing the
+precedence of the rule being considered with that of the lookahead
+token. If the token's precedence is higher, the choice is to shift.
+If the rule's precedence is higher, the choice is to reduce. If they
+have equal precedence, the choice is made based on the associativity of
+that precedence level. The verbose output file made by `-v' (*note

+
+ Not all rules and not all tokens have precedence. If either the
+rule or the lookahead token has no precedence, then the default is to
+shift.

+
+5.4 Context-Dependent Precedence
+================================
+
+Often the precedence of an operator depends on the context. This sounds
+outlandish at first, but it is really very common. For example, a minus
+sign typically has a very high precedence as a unary operator, and a
+somewhat lower precedence (lower than multiplication) as a binary
+operator.
+
+ The Bison precedence declarations, `%left', `%right' and
+`%nonassoc', can only be used once for a given token; so a token has
+only one precedence declared in this way. For context-dependent
+precedence, you need to use an additional mechanism: the `%prec'
+modifier for rules.
+
+ The `%prec' modifier declares the precedence of a particular rule by
+specifying a terminal symbol whose precedence should be used for that
+rule. It's not necessary for that symbol to appear otherwise in the
+rule. The modifier's syntax is:
+
+ %prec TERMINAL-SYMBOL
+
+and it is written after the components of the rule. Its effect is to
+assign the rule the precedence of TERMINAL-SYMBOL, overriding the
+precedence that would be deduced for it in the ordinary way. The
+altered rule precedence then affects how conflicts involving that rule
+are resolved (*note Operator Precedence: Precedence.).
+
+ Here is how `%prec' solves the problem of unary minus. First,
+declare a precedence for a fictitious terminal symbol named `UMINUS'.
+There are no tokens of this type, but the symbol serves to stand for its
+precedence:
+
+ ...
+ %left '+' '-'
+ %left '*'
+ %left UMINUS
+
+ Now the precedence of `UMINUS' can be used in specific rules:
+
+ exp:
+ ...
+ | exp '-' exp
+ ...
+ | '-' exp %prec UMINUS
+

+
+5.5 Parser States
+=================
+
+The function `yyparse' is implemented using a finite-state machine.
+The values pushed on the parser stack are not simply token type codes;
+they represent the entire sequence of terminal and nonterminal symbols
+at or near the top of the stack. The current state collects all the
+information about previous input which is relevant to deciding what to
+do next.
+
+ Each time a lookahead token is read, the current parser state
+together with the type of lookahead token are looked up in a table.
+This table entry can say, "Shift the lookahead token." In this case,
+it also specifies the new parser state, which is pushed onto the top of
+the parser stack. Or it can say, "Reduce using rule number N." This
+means that a certain number of tokens or groupings are taken off the
+top of the stack, and replaced by one grouping. In other words, that
+number of states are popped from the stack, and one new state is pushed.
+
+ There is one other alternative: the table can say that the lookahead
+token is erroneous in the current state. This causes error processing
+to begin (*note Error Recovery::).
+
+\1f
+File: bison.info, Node: Reduce/Reduce, Next: Mysterious Conflicts, Prev: Parser States, Up: Algorithm
+
+5.6 Reduce/Reduce Conflicts
+===========================
+
+A reduce/reduce conflict occurs if there are two or more rules that
+apply to the same sequence of input. This usually indicates a serious
+error in the grammar.
+
+ For example, here is an erroneous attempt to define a sequence of
+zero or more `word' groupings.
+
+ sequence:
+ /* empty */ { printf ("empty sequence\n"); }
+ | maybeword
+ | sequence word { printf ("added word %s\n", $2); }
+ ;
+
+ maybeword:
+ /* empty */ { printf ("empty maybeword\n"); }
+ | word { printf ("single word %s\n", $1); }
+ ;
+
+The error is an ambiguity: there is more than one way to parse a single
+`word' into a `sequence'. It could be reduced to a `maybeword' and
+then into a `sequence' via the second rule. Alternatively,
+nothing-at-all could be reduced into a `sequence' via the first rule,
+and this could be combined with the `word' using the third rule for
+`sequence'.
+
+ There is also more than one way to reduce nothing-at-all into a
+`sequence'. This can be done directly via the first rule, or
+indirectly via `maybeword' and then the second rule.
+
+ You might think that this is a distinction without a difference,
+because it does not change whether any particular input is valid or
+not. But it does affect which actions are run. One parsing order runs
+the second rule's action; the other runs the first rule's action and
+the third rule's action. In this example, the output of the program
+changes.
+
+ Bison resolves a reduce/reduce conflict by choosing to use the rule
+that appears first in the grammar, but it is very risky to rely on
+this. Every reduce/reduce conflict must be studied and usually
+eliminated. Here is the proper way to define `sequence':
+
+ sequence:
+ /* empty */ { printf ("empty sequence\n"); }
+ | sequence word { printf ("added word %s\n", $2); }
+ ;
+
+ Here is another common error that yields a reduce/reduce conflict:
+
+ sequence:
+ /* empty */
+ | sequence words
+ | sequence redirects
+ ;
+
+ words:
+ /* empty */
+ | words word
+ ;
+
+ redirects:
+ /* empty */
+ | redirects redirect
+ ;
+
+The intention here is to define a sequence which can contain either
+`word' or `redirect' groupings. The individual definitions of
+`sequence', `words' and `redirects' are error-free, but the three
+together make a subtle ambiguity: even an empty input can be parsed in
+infinitely many ways!
+
+ Consider: nothing-at-all could be a `words'. Or it could be two
+`words' in a row, or three, or any number. It could equally well be a
+`redirects', or two, or any number. Or it could be a `words' followed
+by three `redirects' and another `words'. And so on.
+
+ Here are two ways to correct these rules. First, to make it a
+single level of sequence:
+
+ sequence:
+ /* empty */
+ | sequence word
+ | sequence redirect
+ ;
+
+ Second, to prevent either a `words' or a `redirects' from being
+empty:
+
+ sequence:
+ /* empty */
+ | sequence words
+ | sequence redirects
+ ;
+
+ words:
+ word
+ | words word
+ ;
+
+ redirects:
+ redirect
+ | redirects redirect
+ ;

+
+5.7 Mysterious Conflicts
+========================
+
+Sometimes reduce/reduce conflicts can occur that don't look warranted.
+Here is an example:
+
+ %token ID
+
+ %%
+ def: param_spec return_spec ',';
+ param_spec:
+ type
+ | name_list ':' type
+ ;
+ return_spec:
+ type
+ | name ':' type
+ ;
+ type: ID;
+ name: ID;
+ name_list:
+ name
+ | name ',' name_list
+ ;
+
+ It would seem that this grammar can be parsed with only a single
+token of lookahead: when a `param_spec' is being read, an `ID' is a
+`name' if a comma or colon follows, or a `type' if another `ID'
+follows. In other words, this grammar is LR(1).
+
+ However, for historical reasons, Bison cannot by default handle all
+LR(1) grammars. In this grammar, two contexts, that after an `ID' at
+the beginning of a `param_spec' and likewise at the beginning of a
+`return_spec', are similar enough that Bison assumes they are the same.
+They appear similar because the same set of rules would be active--the
+rule for reducing to a `name' and that for reducing to a `type'. Bison
+is unable to determine at that stage of processing that the rules would
+require different lookahead tokens in the two contexts, so it makes a
+single parser state for them both. Combining the two contexts causes a
+conflict later. In parser terminology, this occurrence means that the
+grammar is not LALR(1).
+
+ For many practical grammars (specifically those that fall into the
+non-LR(1) class), the limitations of LALR(1) result in difficulties
+beyond just mysterious reduce/reduce conflicts. The best way to fix
+all these problems is to select a different parser table construction
+algorithm. Either IELR(1) or canonical LR(1) would suffice, but the
+former is more efficient and easier to debug during development. *Note
+LR Table Construction::, for details. (Bison's IELR(1) and canonical
+LR(1) implementations are experimental. More user feedback will help
+to stabilize them.)
+
+ If you instead wish to work around LALR(1)'s limitations, you can
+often fix a mysterious conflict by identifying the two parser states
+that are being confused, and adding something to make them look
+distinct. In the above example, adding one rule to `return_spec' as
+follows makes the problem go away:
+
+ %token BOGUS
+ ...
+ %%
+ ...
+ return_spec:
+ type
+ | name ':' type
+ | ID BOGUS /* This rule is never used. */
+ ;
+
+ This corrects the problem because it introduces the possibility of an
+additional active rule in the context after the `ID' at the beginning of
+`return_spec'. This rule is not active in the corresponding context in
+a `param_spec', so the two contexts receive distinct parser states. As
+long as the token `BOGUS' is never generated by `yylex', the added rule
+cannot alter the way actual input is parsed.
+
+ In this particular example, there is another way to solve the
+problem: rewrite the rule for `return_spec' to use `ID' directly
+instead of via `name'. This also causes the two confusing contexts to
+have different sets of active rules, because the one for `return_spec'
+activates the altered rule for `return_spec' rather than the one for
+`name'.
+
+ param_spec:
+ type
+ | name_list ':' type
+ ;
+ return_spec:
+ type
+ | ID ':' type

+
+5.8 Tuning LR
+=============
+
+The default behavior of Bison's LR-based parsers is chosen mostly for
+historical reasons, but that behavior is often not robust. For
+example, in the previous section, we discussed the mysterious conflicts
+that can be produced by LALR(1), Bison's default parser table
+construction algorithm. Another example is Bison's `%error-verbose'
+directive, which instructs the generated parser to produce verbose
+syntax error messages, which can sometimes contain incorrect
+information.
+
+ In this section, we explore several modern features of Bison that
+allow you to tune fundamental aspects of the generated LR-based
+parsers. Some of these features easily eliminate shortcomings like
+those mentioned above. Others can be helpful purely for understanding
+your parser.
+
+ Most of the features discussed in this section are still
+experimental. More user feedback will help to stabilize them.
+
+* Menu:
+
+* LR Table Construction:: Choose a different construction algorithm.

+File: bison.info, Node: LR Table Construction, Next: Default Reductions, Up: Tuning LR
+
+5.8.1 LR Table Construction
+---------------------------
+
+For historical reasons, Bison constructs LALR(1) parser tables by
+default. However, LALR does not possess the full language-recognition
+power of LR. As a result, the behavior of parsers employing LALR
+parser tables is often mysterious. We presented a simple example of
+this effect in *note Mysterious Conflicts::.
+
+ As we also demonstrated in that example, the traditional approach to
+eliminating such mysterious behavior is to restructure the grammar.
+Unfortunately, doing so correctly is often difficult. Moreover, merely
+discovering that LALR causes mysterious behavior in your parser can be
+difficult as well.
+
+ Fortunately, Bison provides an easy way to eliminate the possibility
+of such mysterious behavior altogether. You simply need to activate a
+more powerful parser table construction algorithm by using the `%define
+lr.type' directive.
+
+ -- Directive: %define lr.type TYPE
+ Specify the type of parser tables within the LR(1) family. The
+ accepted values for TYPE are:
+
+ * `lalr' (default)
+
+ * `ielr'
+
+ * `canonical-lr'
+
+ (This feature is experimental. More user feedback will help to
+ stabilize it.)
+
+ For example, to activate IELR, you might add the following directive
+to you grammar file:
+
+ %define lr.type ielr
+
+For the example in *note Mysterious Conflicts::, the mysterious
+conflict is then eliminated, so there is no need to invest time in
+comprehending the conflict or restructuring the grammar to fix it. If,
+during future development, the grammar evolves such that all mysterious
+behavior would have disappeared using just LALR, you need not fear that
+continuing to use IELR will result in unnecessarily large parser tables.
+That is, IELR generates LALR tables when LALR (using a deterministic
+parsing algorithm) is sufficient to support the full
+language-recognition power of LR. Thus, by enabling IELR at the start
+of grammar development, you can safely and completely eliminate the
+need to consider LALR's shortcomings.
+
+ While IELR is almost always preferable, there are circumstances
+where LALR or the canonical LR parser tables described by Knuth (*note
+Knuth 1965: Bibliography.) can be useful. Here we summarize the
+relative advantages of each parser table construction algorithm within
+Bison:
+
+ * LALR
+
+ There are at least two scenarios where LALR can be worthwhile:
+
+ * GLR without static conflict resolution.
+
+ When employing GLR parsers (*note GLR Parsers::), if you do
+ not resolve any conflicts statically (for example, with
+ `%left' or `%prec'), then the parser explores all potential
+ parses of any given input. In this case, the choice of
+ parser table construction algorithm is guaranteed not to alter
+ the language accepted by the parser. LALR parser tables are
+ the smallest parser tables Bison can currently construct, so
+ they may then be preferable. Nevertheless, once you begin to
+ resolve conflicts statically, GLR behaves more like a
+ deterministic parser in the syntactic contexts where those
+ conflicts appear, and so either IELR or canonical LR can then
+ be helpful to avoid LALR's mysterious behavior.
+
+ * Malformed grammars.
+
+ Occasionally during development, an especially malformed
+ grammar with a major recurring flaw may severely impede the
+ IELR or canonical LR parser table construction algorithm.
+ LALR can be a quick way to construct parser tables in order
+ to investigate such problems while ignoring the more subtle
+ differences from IELR and canonical LR.
+
+ * IELR
+
+ IELR (Inadequacy Elimination LR) is a minimal LR algorithm. That
+ is, given any grammar (LR or non-LR), parsers using IELR or
+ canonical LR parser tables always accept exactly the same set of
+ sentences. However, like LALR, IELR merges parser states during
+ parser table construction so that the number of parser states is
+ often an order of magnitude less than for canonical LR. More
+ importantly, because canonical LR's extra parser states may contain
+ duplicate conflicts in the case of non-LR grammars, the number of
+ conflicts for IELR is often an order of magnitude less as well.
+ This effect can significantly reduce the complexity of developing
+ a grammar.
+
+ * Canonical LR
+
+ While inefficient, canonical LR parser tables can be an
+ interesting means to explore a grammar because they possess a
+ property that IELR and LALR tables do not. That is, if
+ `%nonassoc' is not used and default reductions are left disabled
+ (*note Default Reductions::), then, for every left context of
+ every canonical LR state, the set of tokens accepted by that state
+ is guaranteed to be the exact set of tokens that is syntactically
+ acceptable in that left context. It might then seem that an
+ advantage of canonical LR parsers in production is that, under the
+ above constraints, they are guaranteed to detect a syntax error as
+ soon as possible without performing any unnecessary reductions.
+ However, IELR parsers that use LAC are also able to achieve this
+ behavior without sacrificing `%nonassoc' or default reductions.
+ For details and a few caveats of LAC, *note LAC::.
+
+ For a more detailed exposition of the mysterious behavior in LALR
+parsers and the benefits of IELR, *note Denny 2008 March: Bibliography,
+and *note Denny 2010 November: Bibliography.

+
+5.8.2 Default Reductions
+------------------------
+
+After parser table construction, Bison identifies the reduction with the
+largest lookahead set in each parser state. To reduce the size of the
+parser state, traditional Bison behavior is to remove that lookahead
+set and to assign that reduction to be the default parser action. Such
+a reduction is known as a "default reduction".
+
+ Default reductions affect more than the size of the parser tables.
+They also affect the behavior of the parser:
+
+ * Delayed `yylex' invocations.
+
+ A "consistent state" is a state that has only one possible parser
+ action. If that action is a reduction and is encoded as a default
+ reduction, then that consistent state is called a "defaulted
+ state". Upon reaching a defaulted state, a Bison-generated parser
+ does not bother to invoke `yylex' to fetch the next token before
+ performing the reduction. In other words, whether default
+ reductions are enabled in consistent states determines how soon a
+ Bison-generated parser invokes `yylex' for a token: immediately
+ when it _reaches_ that token in the input or when it eventually
+ _needs_ that token as a lookahead to determine the next parser
+ action. Traditionally, default reductions are enabled, and so the
+ parser exhibits the latter behavior.
+
+ The presence of defaulted states is an important consideration when
+ designing `yylex' and the grammar file. That is, if the behavior
+ of `yylex' can influence or be influenced by the semantic actions
+ associated with the reductions in defaulted states, then the delay
+ of the next `yylex' invocation until after those reductions is
+ significant. For example, the semantic actions might pop a scope
+ stack that `yylex' uses to determine what token to return. Thus,
+ the delay might be necessary to ensure that `yylex' does not look
+ up the next token in a scope that should already be considered
+ closed.
+
+ * Delayed syntax error detection.
+
+ When the parser fetches a new token by invoking `yylex', it checks
+ whether there is an action for that token in the current parser
+ state. The parser detects a syntax error if and only if either
+ (1) there is no action for that token or (2) the action for that
+ token is the error action (due to the use of `%nonassoc').
+ However, if there is a default reduction in that state (which
+ might or might not be a defaulted state), then it is impossible
+ for condition 1 to exist. That is, all tokens have an action.
+ Thus, the parser sometimes fails to detect the syntax error until
+ it reaches a later state.
+
+ While default reductions never cause the parser to accept
+ syntactically incorrect sentences, the delay of syntax error
+ detection can have unexpected effects on the behavior of the
+ parser. However, the delay can be caused anyway by parser state
+ merging and the use of `%nonassoc', and it can be fixed by another
+ Bison feature, LAC. We discuss the effects of delayed syntax
+ error detection and LAC more in the next section (*note LAC::).
+
+ For canonical LR, the only default reduction that Bison enables by
+default is the accept action, which appears only in the accepting
+state, which has no other action and is thus a defaulted state.
+However, the default accept action does not delay any `yylex'
+invocation or syntax error detection because the accept action ends the
+parse.
+
+ For LALR and IELR, Bison enables default reductions in nearly all
+states by default. There are only two exceptions. First, states that
+have a shift action on the `error' token do not have default reductions
+because delayed syntax error detection could then prevent the `error'
+token from ever being shifted in that state. However, parser state
+merging can cause the same effect anyway, and LAC fixes it in both
+cases, so future versions of Bison might drop this exception when LAC
+is activated. Second, GLR parsers do not record the default reduction
+as the action on a lookahead token for which there is a conflict. The
+correct action in this case is to split the parse instead.
+
+ To adjust which states have default reductions enabled, use the
+`%define lr.default-reductions' directive.
+
+ -- Directive: %define lr.default-reductions WHERE
+ Specify the kind of states that are permitted to contain default
+ reductions. The accepted values of WHERE are:
+ * `most' (default for LALR and IELR)
+
+ * `consistent'
+
+ * `accepting' (default for canonical LR)
+
+ (The ability to specify where default reductions are permitted is
+ experimental. More user feedback will help to stabilize it.)
+

+File: bison.info, Node: LAC, Next: Unreachable States, Prev: Default Reductions, Up: Tuning LR
+
+5.8.3 LAC
+---------
+
+Canonical LR, IELR, and LALR can suffer from a couple of problems upon
+encountering a syntax error. First, the parser might perform additional
+parser stack reductions before discovering the syntax error. Such
+reductions can perform user semantic actions that are unexpected because
+they are based on an invalid token, and they cause error recovery to
+begin in a different syntactic context than the one in which the
+invalid token was encountered. Second, when verbose error messages are
+enabled (*note Error Reporting::), the expected token list in the
+syntax error message can both contain invalid tokens and omit valid
+tokens.
+
+ The culprits for the above problems are `%nonassoc', default
+reductions in inconsistent states (*note Default Reductions::), and
+parser state merging. Because IELR and LALR merge parser states, they
+suffer the most. Canonical LR can suffer only if `%nonassoc' is used
+or if default reductions are enabled for inconsistent states.
+
+ LAC (Lookahead Correction) is a new mechanism within the parsing
+algorithm that solves these problems for canonical LR, IELR, and LALR
+without sacrificing `%nonassoc', default reductions, or state merging.
+You can enable LAC with the `%define parse.lac' directive.
+
+ -- Directive: %define parse.lac VALUE
+ Enable LAC to improve syntax error handling.
+ * `none' (default)
+
+ * `full'
+ (This feature is experimental. More user feedback will help to
+ stabilize it. Moreover, it is currently only available for
+ deterministic parsers in C.)
+
+ Conceptually, the LAC mechanism is straight-forward. Whenever the
+parser fetches a new token from the scanner so that it can determine
+the next parser action, it immediately suspends normal parsing and
+performs an exploratory parse using a temporary copy of the normal
+parser state stack. During this exploratory parse, the parser does not
+perform user semantic actions. If the exploratory parse reaches a
+shift action, normal parsing then resumes on the normal parser stacks.
+If the exploratory parse reaches an error instead, the parser reports a
+syntax error. If verbose syntax error messages are enabled, the parser
+must then discover the list of expected tokens, so it performs a
+separate exploratory parse for each token in the grammar.
+
+ There is one subtlety about the use of LAC. That is, when in a
+consistent parser state with a default reduction, the parser will not
+attempt to fetch a token from the scanner because no lookahead is
+needed to determine the next parser action. Thus, whether default
+reductions are enabled in consistent states (*note Default
+Reductions::) affects how soon the parser detects a syntax error:
+immediately when it _reaches_ an erroneous token or when it eventually
+_needs_ that token as a lookahead to determine the next parser action.
+The latter behavior is probably more intuitive, so Bison currently
+provides no way to achieve the former behavior while default reductions
+are enabled in consistent states.
+
+ Thus, when LAC is in use, for some fixed decision of whether to
+enable default reductions in consistent states, canonical LR and IELR
+behave almost exactly the same for both syntactically acceptable and
+syntactically unacceptable input. While LALR still does not support
+the full language-recognition power of canonical LR and IELR, LAC at
+least enables LALR's syntax error handling to correctly reflect LALR's
+language-recognition power.
+
+ There are a few caveats to consider when using LAC:
+
+ * Infinite parsing loops.
+
+ IELR plus LAC does have one shortcoming relative to canonical LR.
+ Some parsers generated by Bison can loop infinitely. LAC does not
+ fix infinite parsing loops that occur between encountering a
+ syntax error and detecting it, but enabling canonical LR or
+ disabling default reductions sometimes does.
+
+ * Verbose error message limitations.
+
+ Because of internationalization considerations, Bison-generated
+ parsers limit the size of the expected token list they are willing
+ to report in a verbose syntax error message. If the number of
+ expected tokens exceeds that limit, the list is simply dropped
+ from the message. Enabling LAC can increase the size of the list
+ and thus cause the parser to drop it. Of course, dropping the
+ list is better than reporting an incorrect list.
+
+ * Performance.
+
+ Because LAC requires many parse actions to be performed twice, it
+ can have a performance penalty. However, not all parse actions
+ must be performed twice. Specifically, during a series of default
+ reductions in consistent states and shift actions, the parser
+ never has to initiate an exploratory parse. Moreover, the most
+ time-consuming tasks in a parse are often the file I/O, the
+ lexical analysis performed by the scanner, and the user's semantic
+ actions, but none of these are performed during the exploratory
+ parse. Finally, the base of the temporary stack used during an
+ exploratory parse is a pointer into the normal parser state stack
+ so that the stack is never physically copied. In our experience,
+ the performance penalty of LAC has proved insignificant for
+ practical grammars.
+
+ While the LAC algorithm shares techniques that have been recognized
+in the parser community for years, for the publication that introduces
+LAC, *note Denny 2010 May: Bibliography.
+

+File: bison.info, Node: Unreachable States, Prev: LAC, Up: Tuning LR
+
+5.8.4 Unreachable States
+------------------------
+
+If there exists no sequence of transitions from the parser's start
+state to some state S, then Bison considers S to be an "unreachable
+state". A state can become unreachable during conflict resolution if
+Bison disables a shift action leading to it from a predecessor state.
+
+ By default, Bison removes unreachable states from the parser after
+conflict resolution because they are useless in the generated parser.
+However, keeping unreachable states is sometimes useful when trying to
+understand the relationship between the parser and the grammar.
+
+ -- Directive: %define lr.keep-unreachable-states VALUE
+ Request that Bison allow unreachable states to remain in the
+ parser tables. VALUE must be a Boolean. The default is `false'.
+
+ There are a few caveats to consider:
+
+ * Missing or extraneous warnings.
+
+ Unreachable states may contain conflicts and may use rules not
+ used in any other state. Thus, keeping unreachable states may
+ induce warnings that are irrelevant to your parser's behavior, and
+ it may eliminate warnings that are relevant. Of course, the
+ change in warnings may actually be relevant to a parser table
+ analysis that wants to keep unreachable states, so this behavior
+ will likely remain in future Bison releases.
+
+ * Other useless states.
+
+ While Bison is able to remove unreachable states, it is not
+ guaranteed to remove other kinds of useless states. Specifically,
+ when Bison disables reduce actions during conflict resolution,
+ some goto actions may become useless, and thus some additional
+ states may become useless. If Bison were to compute which goto
+ actions were useless and then disable those actions, it could
+ identify such states as unreachable and then remove those states.
+ However, Bison does not compute which goto actions are useless.

+
+5.9 Generalized LR (GLR) Parsing
+================================
+
+Bison produces _deterministic_ parsers that choose uniquely when to
+reduce and which reduction to apply based on a summary of the preceding
+input and on one extra token of lookahead. As a result, normal Bison
+handles a proper subset of the family of context-free languages.
+Ambiguous grammars, since they have strings with more than one possible
+sequence of reductions cannot have deterministic parsers in this sense.
+The same is true of languages that require more than one symbol of
+lookahead, since the parser lacks the information necessary to make a
+decision at the point it must be made in a shift-reduce parser.
+Finally, as previously mentioned (*note Mysterious Conflicts::), there
+are languages where Bison's default choice of how to summarize the
+input seen so far loses necessary information.
+
+ When you use the `%glr-parser' declaration in your grammar file,
+Bison generates a parser that uses a different algorithm, called
+Generalized LR (or GLR). A Bison GLR parser uses the same basic
+algorithm for parsing as an ordinary Bison parser, but behaves
+differently in cases where there is a shift-reduce conflict that has not
+been resolved by precedence rules (*note Precedence::) or a
+reduce-reduce conflict. When a GLR parser encounters such a situation,
+it effectively _splits_ into a several parsers, one for each possible
+shift or reduction. These parsers then proceed as usual, consuming
+tokens in lock-step. Some of the stacks may encounter other conflicts
+and split further, with the result that instead of a sequence of states,
+a Bison GLR parsing stack is what is in effect a tree of states.
+
+ In effect, each stack represents a guess as to what the proper parse
+is. Additional input may indicate that a guess was wrong, in which case
+the appropriate stack silently disappears. Otherwise, the semantics
+actions generated in each stack are saved, rather than being executed
+immediately. When a stack disappears, its saved semantic actions never
+get executed. When a reduction causes two stacks to become equivalent,
+their sets of semantic actions are both saved with the state that
+results from the reduction. We say that two stacks are equivalent when
+they both represent the same sequence of states, and each pair of
+corresponding states represents a grammar symbol that produces the same
+segment of the input token stream.
+
+ Whenever the parser makes a transition from having multiple states
+to having one, it reverts to the normal deterministic parsing
+algorithm, after resolving and executing the saved-up actions. At this
+transition, some of the states on the stack will have semantic values
+that are sets (actually multisets) of possible actions. The parser
+tries to pick one of the actions by first finding one whose rule has
+the highest dynamic precedence, as set by the `%dprec' declaration.
+Otherwise, if the alternative actions are not ordered by precedence,
+but there the same merging function is declared for both rules by the
+`%merge' declaration, Bison resolves and evaluates both and then calls
+the merge function on the result. Otherwise, it reports an ambiguity.
+
+ It is possible to use a data structure for the GLR parsing tree that
+permits the processing of any LR(1) grammar in linear time (in the size
+of the input), any unambiguous (not necessarily LR(1)) grammar in
+quadratic worst-case time, and any general (possibly ambiguous)
+context-free grammar in cubic worst-case time. However, Bison currently
+uses a simpler data structure that requires time proportional to the
+length of the input times the maximum number of stacks required for any
+prefix of the input. Thus, really ambiguous or nondeterministic
+grammars can require exponential time and space to process. Such badly
+behaving examples, however, are not generally of practical interest.
+Usually, nondeterminism in a grammar is local--the parser is "in doubt"
+only for a few tokens at a time. Therefore, the current data structure
+should generally be adequate. On LR(1) portions of a grammar, in
+particular, it is only slightly slower than with the deterministic
+LR(1) Bison parser.
+
+ For a more detailed exposition of GLR parsers, *note Scott 2000:
+Bibliography.

+
+5.10 Memory Management, and How to Avoid Memory Exhaustion
+==========================================================
+
+The Bison parser stack can run out of memory if too many tokens are
+shifted and not reduced. When this happens, the parser function
+`yyparse' calls `yyerror' and then returns 2.
+
+ Because Bison parsers have growing stacks, hitting the upper limit
+usually results from using a right recursion instead of a left
+recursion, see *note Recursive Rules: Recursion.
+
+ By defining the macro `YYMAXDEPTH', you can control how deep the
+parser stack can become before memory is exhausted. Define the macro
+with a value that is an integer. This value is the maximum number of
+tokens that can be shifted (and not reduced) before overflow.
+
+ The stack space allowed is not necessarily allocated. If you
+specify a large value for `YYMAXDEPTH', the parser normally allocates a
+small stack at first, and then makes it bigger by stages as needed.
+This increasing allocation happens automatically and silently.
+Therefore, you do not need to make `YYMAXDEPTH' painfully small merely
+to save space for ordinary inputs that do not need much stack.
+
+ However, do not allow `YYMAXDEPTH' to be a value so large that
+arithmetic overflow could occur when calculating the size of the stack
+space. Also, do not allow `YYMAXDEPTH' to be less than `YYINITDEPTH'.
+
+ The default value of `YYMAXDEPTH', if you do not define it, is 10000.
+
+ You can control how much stack is allocated initially by defining the
+macro `YYINITDEPTH' to a positive integer. For the deterministic
+parser in C, this value must be a compile-time constant unless you are
+assuming C99 or some other target language or compiler that allows
+variable-length arrays. The default is 200.
+
+ Do not allow `YYINITDEPTH' to be greater than `YYMAXDEPTH'.
+
+ Because of semantic differences between C and C++, the deterministic
+parsers in C produced by Bison cannot grow when compiled by C++
+compilers. In this precise case (compiling a C parser as C++) you are
+suggested to grow `YYINITDEPTH'. The Bison maintainers hope to fix
+this deficiency in a future release.

+
+6 Error Recovery
+****************
+
+It is not usually acceptable to have a program terminate on a syntax
+error. For example, a compiler should recover sufficiently to parse the
+rest of the input file and check it for errors; a calculator should
+accept another expression.
+
+ In a simple interactive command parser where each input is one line,
+it may be sufficient to allow `yyparse' to return 1 on error and have
+the caller ignore the rest of the input line when that happens (and
+then call `yyparse' again). But this is inadequate for a compiler,
+because it forgets all the syntactic context leading up to the error.
+A syntax error deep within a function in the compiler input should not
+cause the compiler to treat the following line like the beginning of a
+source file.
+
+ You can define how to recover from a syntax error by writing rules to
+recognize the special token `error'. This is a terminal symbol that is
+always defined (you need not declare it) and reserved for error
+handling. The Bison parser generates an `error' token whenever a
+syntax error happens; if you have provided a rule to recognize this
+token in the current context, the parse can continue.
+
+ For example:
+
+ stmts:
+ /* empty string */
+ | stmts '\n'
+ | stmts exp '\n'
+ | stmts error '\n'
+
+ The fourth rule in this example says that an error followed by a
+newline makes a valid addition to any `stmts'.
+
+ What happens if a syntax error occurs in the middle of an `exp'? The
+error recovery rule, interpreted strictly, applies to the precise
+sequence of a `stmts', an `error' and a newline. If an error occurs in
+the middle of an `exp', there will probably be some additional tokens
+and subexpressions on the stack after the last `stmts', and there will
+be tokens to read before the next newline. So the rule is not
+applicable in the ordinary way.
+
+ But Bison can force the situation to fit the rule, by discarding
+part of the semantic context and part of the input. First it discards
+states and objects from the stack until it gets back to a state in
+which the `error' token is acceptable. (This means that the
+subexpressions already parsed are discarded, back to the last complete
+`stmts'.) At this point the `error' token can be shifted. Then, if
+the old lookahead token is not acceptable to be shifted next, the
+parser reads tokens and discards them until it finds a token which is
+acceptable. In this example, Bison reads and discards input until the
+next newline so that the fourth rule can apply. Note that discarded
+symbols are possible sources of memory leaks, see *note Freeing
+Discarded Symbols: Destructor Decl, for a means to reclaim this memory.
+
+ The choice of error rules in the grammar is a choice of strategies
+for error recovery. A simple and useful strategy is simply to skip the
+rest of the current input line or current statement if an error is
+detected:
+
+ stmt: error ';' /* On error, skip until ';' is read. */
+
+ It is also useful to recover to the matching close-delimiter of an
+opening-delimiter that has already been parsed. Otherwise the
+close-delimiter will probably appear to be unmatched, and generate
+another, spurious error message:
+
+ primary:
+ '(' expr ')'
+ | '(' error ')'
+ ...
+ ;
+
+ Error recovery strategies are necessarily guesses. When they guess
+wrong, one syntax error often leads to another. In the above example,
+the error recovery rule guesses that an error is due to bad input
+within one `stmt'. Suppose that instead a spurious semicolon is
+inserted in the middle of a valid `stmt'. After the error recovery
+rule recovers from the first error, another syntax error will be found
+straightaway, since the text following the spurious semicolon is also
+an invalid `stmt'.
+
+ To prevent an outpouring of error messages, the parser will output
+no error message for another syntax error that happens shortly after
+the first; only after three consecutive input tokens have been
+successfully shifted will error messages resume.
+
+ Note that rules which accept the `error' token may have actions, just
+as any other rules can.
+
+ You can make error messages resume immediately by using the macro
+`yyerrok' in an action. If you do this in the error rule's action, no
+error messages will be suppressed. This macro requires no arguments;
+`yyerrok;' is a valid C statement.
+
+ The previous lookahead token is reanalyzed immediately after an
+error. If this is unacceptable, then the macro `yyclearin' may be used
+to clear this token. Write the statement `yyclearin;' in the error
+rule's action. *Note Special Features for Use in Actions: Action
+Features.
+
+ For example, suppose that on a syntax error, an error handling
+routine is called that advances the input stream to some point where
+parsing should once again commence. The next symbol returned by the
+lexical scanner is probably correct. The previous lookahead token
+ought to be discarded with `yyclearin;'.
+
+ The expression `YYRECOVERING ()' yields 1 when the parser is
+recovering from a syntax error, and 0 otherwise. Syntax error
+diagnostics are suppressed while recovering from a syntax error.

+
+7 Handling Context Dependencies
+*******************************
+
+The Bison paradigm is to parse tokens first, then group them into larger
+syntactic units. In many languages, the meaning of a token is affected
+by its context. Although this violates the Bison paradigm, certain
+techniques (known as "kludges") may enable you to write Bison parsers
+for such languages.
+
+* Menu:
+
+* Semantic Tokens:: Token parsing can depend on the semantic context.
+* Lexical Tie-ins:: Token parsing can depend on the syntactic context.
+* Tie-in Recovery:: Lexical tie-ins have implications for how
+ error recovery rules must be written.
+
+ (Actually, "kludge" means any technique that gets its job done but is
+neither clean nor robust.)
+
+\1f
+File: bison.info, Node: Semantic Tokens, Next: Lexical Tie-ins, Up: Context Dependency
+
+7.1 Semantic Info in Token Types
+================================
+
+The C language has a context dependency: the way an identifier is used
+depends on what its current meaning is. For example, consider this:
+
+ foo (x);
+
+ This looks like a function call statement, but if `foo' is a typedef
+name, then this is actually a declaration of `x'. How can a Bison
+parser for C decide how to parse this input?
+
+ The method used in GNU C is to have two different token types,
+`IDENTIFIER' and `TYPENAME'. When `yylex' finds an identifier, it
+looks up the current declaration of the identifier in order to decide
+which token type to return: `TYPENAME' if the identifier is declared as
+a typedef, `IDENTIFIER' otherwise.
+
+ The grammar rules can then express the context dependency by the
+choice of token type to recognize. `IDENTIFIER' is accepted as an
+expression, but `TYPENAME' is not. `TYPENAME' can start a declaration,
+but `IDENTIFIER' cannot. In contexts where the meaning of the
+identifier is _not_ significant, such as in declarations that can
+shadow a typedef name, either `TYPENAME' or `IDENTIFIER' is
+accepted--there is one rule for each of the two token types.
+
+ This technique is simple to use if the decision of which kinds of
+identifiers to allow is made at a place close to where the identifier is
+parsed. But in C this is not always so: C allows a declaration to
+redeclare a typedef name provided an explicit type has been specified
+earlier:
+
+ typedef int foo, bar;
+ int baz (void)
+ {
+ static bar (bar); /* redeclare `bar' as static variable */
+ extern foo foo (foo); /* redeclare `foo' as function */
+ return foo (bar);
+ }
+
+ Unfortunately, the name being declared is separated from the
+declaration construct itself by a complicated syntactic structure--the
+"declarator".
+
+ As a result, part of the Bison parser for C needs to be duplicated,
+with all the nonterminal names changed: once for parsing a declaration
+in which a typedef name can be redefined, and once for parsing a
+declaration in which that can't be done. Here is a part of the
+duplication, with actions omitted for brevity:
+
+ initdcl:
+ declarator maybeasm '=' init
+ | declarator maybeasm
+ ;
+
+ notype_initdcl:
+ notype_declarator maybeasm '=' init
+ | notype_declarator maybeasm
+ ;
+
+Here `initdcl' can redeclare a typedef name, but `notype_initdcl'
+cannot. The distinction between `declarator' and `notype_declarator'
+is the same sort of thing.
+
+ There is some similarity between this technique and a lexical tie-in
+(described next), in that information which alters the lexical analysis
+is changed during parsing by other parts of the program. The
+difference is here the information is global, and is used for other
+purposes in the program. A true lexical tie-in has a special-purpose
+flag controlled by the syntactic context.
+
+\1f
+File: bison.info, Node: Lexical Tie-ins, Next: Tie-in Recovery, Prev: Semantic Tokens, Up: Context Dependency
+
+7.2 Lexical Tie-ins
+===================
+
+One way to handle context-dependency is the "lexical tie-in": a flag
+which is set by Bison actions, whose purpose is to alter the way tokens
+are parsed.
+
+ For example, suppose we have a language vaguely like C, but with a
+special construct `hex (HEX-EXPR)'. After the keyword `hex' comes an
+expression in parentheses in which all integers are hexadecimal. In
+particular, the token `a1b' must be treated as an integer rather than
+as an identifier if it appears in that context. Here is how you can do
+it:
+
+ %{
+ int hexflag;
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+ %%
+ ...
+ expr:
+ IDENTIFIER
+ | constant
+ | HEX '(' { hexflag = 1; }
+ expr ')' { hexflag = 0; $$ = $4; }
+ | expr '+' expr { $$ = make_sum ($1, $3); }
+ ...
+ ;
+
+ constant:
+ INTEGER
+ | STRING
+ ;
+
+Here we assume that `yylex' looks at the value of `hexflag'; when it is
+nonzero, all integers are parsed in hexadecimal, and tokens starting
+with letters are parsed as integers if possible.
+
+ The declaration of `hexflag' shown in the prologue of the grammar
+file is needed to make it accessible to the actions (*note The
+Prologue: Prologue.). You must also write the code in `yylex' to obey
+the flag.
+
+\1f
+File: bison.info, Node: Tie-in Recovery, Prev: Lexical Tie-ins, Up: Context Dependency
+
+7.3 Lexical Tie-ins and Error Recovery
+======================================
+
+Lexical tie-ins make strict demands on any error recovery rules you
+have. *Note Error Recovery::.
+
+ The reason for this is that the purpose of an error recovery rule is
+to abort the parsing of one construct and resume in some larger
+construct. For example, in C-like languages, a typical error recovery
+rule is to skip tokens until the next semicolon, and then start a new
+statement, like this:
+
+ stmt:
+ expr ';'
+ | IF '(' expr ')' stmt { ... }
+ ...
+ | error ';' { hexflag = 0; }
+ ;
+
+ If there is a syntax error in the middle of a `hex (EXPR)'
+construct, this error rule will apply, and then the action for the
+completed `hex (EXPR)' will never run. So `hexflag' would remain set
+for the entire rest of the input, or until the next `hex' keyword,
+causing identifiers to be misinterpreted as integers.
+
+ To avoid this problem the error recovery rule itself clears
+`hexflag'.
+
+ There may also be an error recovery rule that works within
+expressions. For example, there could be a rule which applies within
+parentheses and skips to the close-parenthesis:
+
+ expr:
+ ...
+ | '(' expr ')' { $$ = $2; }
+ | '(' error ')'
+ ...
+
+ If this rule acts within the `hex' construct, it is not going to
+abort that construct (since it applies to an inner level of parentheses
+within the construct). Therefore, it should not clear the flag: the
+rest of the `hex' construct should be parsed with the flag still in
+effect.
+
+ What if there is an error recovery rule which might abort out of the
+`hex' construct or might not, depending on circumstances? There is no
+way you can write the action to determine whether a `hex' construct is
+being aborted or not. So if you are using a lexical tie-in, you had
+better make sure your error recovery rules are not of this kind. Each
+rule must be such that you can be sure that it always will, or always
+won't, have to clear the flag.

+8 Debugging Your Parser
+***********************
+
+Developing a parser can be a challenge, especially if you don't
+understand the algorithm (*note The Bison Parser Algorithm:
+Algorithm.). This chapter explains how to generate and read the
+detailed description of the automaton, and how to enable and understand
+the parser run-time traces.
+
+* Menu:
+
+* Understanding:: Understanding the structure of your parser.
+* Tracing:: Tracing the execution of your parser.
+
+\1f
+File: bison.info, Node: Understanding, Next: Tracing, Up: Debugging
+
+8.1 Understanding Your Parser
+=============================
+
+As documented elsewhere (*note The Bison Parser Algorithm: Algorithm.)
+Bison parsers are "shift/reduce automata". In some cases (much more
+frequent than one would hope), looking at this automaton is required to
+tune or simply fix a parser. Bison provides two different
+representation of it, either textually or graphically (as a DOT file).
+
+ The textual file is generated when the options `--report' or
+`--verbose' are specified, see *note Invoking Bison: Invocation. Its
+name is made by removing `.tab.c' or `.c' from the parser
+implementation file name, and adding `.output' instead. Therefore, if
+the grammar file is `foo.y', then the parser implementation file is
+called `foo.tab.c' by default. As a consequence, the verbose output
+file is called `foo.output'.
+
+ The following grammar file, `calc.y', will be used in the sequel:
+
+ %token NUM STR
+ %left '+' '-'
+ %left '*'
+ %%
+ exp:
+ exp '+' exp
+ | exp '-' exp
+ | exp '*' exp
+ | exp '/' exp
+ | NUM
+ ;
+ useless: STR;
+ %%
+
+ `bison' reports:
+
+ calc.y: warning: 1 nonterminal useless in grammar
+ calc.y: warning: 1 rule useless in grammar
+ calc.y:11.1-7: warning: nonterminal useless in grammar: useless
+ calc.y:11.10-12: warning: rule useless in grammar: useless: STR
+ calc.y: conflicts: 7 shift/reduce
+
+ When given `--report=state', in addition to `calc.tab.c', it creates
+a file `calc.output' with contents detailed below. The order of the
+output and the exact presentation might vary, but the interpretation is
+the same.
+
+The first section reports useless tokens, nonterminals and rules.
+Useless nonterminals and rules are removed in order to produce a
+smaller parser, but useless tokens are preserved, since they might be
+used by the scanner (note the difference between "useless" and "unused"
+below):
+
+ Nonterminals useless in grammar
+ useless
+
+ Terminals unused in grammar
+ STR
+
+ Rules useless in grammar
+ 6 useless: STR
+
+The next section lists states that still have conflicts.
+
+ State 8 conflicts: 1 shift/reduce
+ State 9 conflicts: 1 shift/reduce
+ State 10 conflicts: 1 shift/reduce
+ State 11 conflicts: 4 shift/reduce
+
+Then Bison reproduces the exact grammar it used:
+
+ Grammar
+
+ 0 $accept: exp $end
+
+ 1 exp: exp '+' exp
+ 2 | exp '-' exp
+ 3 | exp '*' exp
+ 4 | exp '/' exp
+ 5 | NUM
+
+and reports the uses of the symbols:
+
+ Terminals, with rules where they appear
+
+ $end (0) 0
+ '*' (42) 3
+ '+' (43) 1
+ '-' (45) 2
+ '/' (47) 4
+ error (256)
+ NUM (258) 5
+ STR (259)
+
+ Nonterminals, with rules where they appear
+
+ $accept (9)
+ on left: 0
+ exp (10)
+ on left: 1 2 3 4 5, on right: 0 1 2 3 4
+
+Bison then proceeds onto the automaton itself, describing each state
+with its set of "items", also known as "pointed rules". Each item is a
+production rule together with a point (`.') marking the location of the
+input cursor.
+
+ state 0
+
+ 0 $accept: . exp $end
+
+ NUM shift, and go to state 1
+
+ exp go to state 2
+
+ This reads as follows: "state 0 corresponds to being at the very
+beginning of the parsing, in the initial rule, right before the start
+symbol (here, `exp'). When the parser returns to this state right
+after having reduced a rule that produced an `exp', the control flow
+jumps to state 2. If there is no such transition on a nonterminal
+symbol, and the lookahead is a `NUM', then this token is shifted onto
+the parse stack, and the control flow jumps to state 1. Any other
+lookahead triggers a syntax error."
+
+ Even though the only active rule in state 0 seems to be rule 0, the
+report lists `NUM' as a lookahead token because `NUM' can be at the
+beginning of any rule deriving an `exp'. By default Bison reports the
+so-called "core" or "kernel" of the item set, but if you want to see
+more detail you can invoke `bison' with `--report=itemset' to list the
+derived items as well:
+
+ state 0
+
+ 0 $accept: . exp $end
+ 1 exp: . exp '+' exp
+ 2 | . exp '-' exp
+ 3 | . exp '*' exp
+ 4 | . exp '/' exp
+ 5 | . NUM
+
+ NUM shift, and go to state 1
+
+ exp go to state 2
+
+In the state 1...
+
+ state 1
+
+ 5 exp: NUM .
+
+ $default reduce using rule 5 (exp)
+
+the rule 5, `exp: NUM;', is completed. Whatever the lookahead token
+(`$default'), the parser will reduce it. If it was coming from state
+0, then, after this reduction it will return to state 0, and will jump
+to state 2 (`exp: go to state 2').
+
+ state 2
+
+ 0 $accept: exp . $end
+ 1 exp: exp . '+' exp
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ $end shift, and go to state 3
+ '+' shift, and go to state 4
+ '-' shift, and go to state 5
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+In state 2, the automaton can only shift a symbol. For instance,
+because of the item `exp: exp . '+' exp', if the lookahead is `+' it is
+shifted onto the parse stack, and the automaton jumps to state 4,
+corresponding to the item `exp: exp '+' . exp'. Since there is no
+default action, any lookahead not listed triggers a syntax error.
+
+ The state 3 is named the "final state", or the "accepting state":
+
+ state 3
+
+ 0 $accept: exp $end .
+
+ $default accept
+
+the initial rule is completed (the start symbol and the end-of-input
+were read), the parsing exits successfully.
+
+ The interpretation of states 4 to 7 is straightforward, and is left
+to the reader.
+
+ state 4
+
+ 1 exp: exp '+' . exp

+
+ exp go to state 9
+
+
+ state 6
+
+ 3 exp: exp '*' . exp
+
+ NUM shift, and go to state 1
+
+ exp go to state 10
+
+
+ state 7
+
+ 4 exp: exp '/' . exp
+
+ NUM shift, and go to state 1
+
+ exp go to state 11
+
+ As was announced in beginning of the report, `State 8 conflicts: 1
+shift/reduce':
+
+ state 8
+
+ 1 exp: exp . '+' exp
+ 1 | exp '+' exp .
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+ '/' [reduce using rule 1 (exp)]
+ $default reduce using rule 1 (exp)
+
+ Indeed, there are two actions associated to the lookahead `/':
+either shifting (and going to state 7), or reducing rule 1. The
+conflict means that either the grammar is ambiguous, or the parser lacks
+information to make the right decision. Indeed the grammar is
+ambiguous, as, since we did not specify the precedence of `/', the
+sentence `NUM + NUM / NUM' can be parsed as `NUM + (NUM / NUM)', which
+corresponds to shifting `/', or as `(NUM + NUM) / NUM', which
+corresponds to reducing rule 1.
+
+ Because in deterministic parsing a single decision can be made, Bison
+arbitrarily chose to disable the reduction, see *note Shift/Reduce
+Conflicts: Shift/Reduce. Discarded actions are reported between square
+brackets.
+
+ Note that all the previous states had a single possible action:
+either shifting the next token and going to the corresponding state, or
+reducing a single rule. In the other cases, i.e., when shifting _and_
+reducing is possible or when _several_ reductions are possible, the
+lookahead is required to select the action. State 8 is one such state:
+if the lookahead is `*' or `/' then the action is shifting, otherwise
+the action is reducing rule 1. In other words, the first two items,
+corresponding to rule 1, are not eligible when the lookahead token is
+`*', since we specified that `*' has higher precedence than `+'. More
+generally, some items are eligible only with some set of possible
+lookahead tokens. When run with `--report=lookahead', Bison specifies
+these lookahead tokens:
+
+ state 8
+
+ 1 exp: exp . '+' exp
+ 1 | exp '+' exp . [$end, '+', '-', '/']
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+ '/' [reduce using rule 1 (exp)]
+ $default reduce using rule 1 (exp)
+
+ Note however that while `NUM + NUM / NUM' is ambiguous (which
+results in the conflicts on `/'), `NUM + NUM * NUM' is not: the
+conflict was solved thanks to associativity and precedence directives.
+If invoked with `--report=solved', Bison includes information about the
+solved conflicts in the report:
+
+ Conflict between rule 1 and token '+' resolved as reduce (%left '+').
+ Conflict between rule 1 and token '-' resolved as reduce (%left '-').
+ Conflict between rule 1 and token '*' resolved as shift ('+' < '*').
+
+ The remaining states are similar:
+
+ state 9
+
+ 1 exp: exp . '+' exp
+ 2 | exp . '-' exp
+ 2 | exp '-' exp .
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+

+ '-' [reduce using rule 4 (exp)]
+ '*' [reduce using rule 4 (exp)]
+ '/' [reduce using rule 4 (exp)]
+ $default reduce using rule 4 (exp)
+
+Observe that state 11 contains conflicts not only due to the lack of
+precedence of `/' with respect to `+', `-', and `*', but also because
+the associativity of `/' is not specified.

+8.2 Tracing Your Parser
+=======================
+
+When a Bison grammar compiles properly but parses "incorrectly", the
+`yydebug' parser-trace feature helps figuring out why.
+
+* Menu:
+
+* Enabling Traces:: Activating run-time trace support
+* Mfcalc Traces:: Extending `mfcalc' to support traces
+* The YYPRINT Macro:: Obsolete interface for semantic value reports
+
+\1f
+File: bison.info, Node: Enabling Traces, Next: Mfcalc Traces, Up: Tracing
+
+8.2.1 Enabling Traces
+---------------------
+
+There are several means to enable compilation of trace facilities:
+
+the macro `YYDEBUG'
+ Define the macro `YYDEBUG' to a nonzero value when you compile the
+ parser. This is compliant with POSIX Yacc. You could use
+ `-DYYDEBUG=1' as a compiler option or you could put `#define
+ YYDEBUG 1' in the prologue of the grammar file (*note The
+ Prologue: Prologue.).
+
+ If the `%define' variable `api.prefix' is used (*note Multiple
+ Parsers in the Same Program: Multiple Parsers.), for instance
+ `%define api.prefix x', then if `CDEBUG' is defined, its value
+ controls the tracing feature (enabled iff nonzero); otherwise
+ tracing is enabled iff `YYDEBUG' is nonzero.
+
+the option `-t' (POSIX Yacc compliant)
+the option `--debug' (Bison extension)
+ Use the `-t' option when you run Bison (*note Invoking Bison:
+ Invocation.). With `%define api.prefix c', it defines `CDEBUG' to
+ 1, otherwise it defines `YYDEBUG' to 1.
+
+the directive `%debug'
+ Add the `%debug' directive (*note Bison Declaration Summary: Decl
+ Summary.). This is a Bison extension, especially useful for
+ languages that don't use a preprocessor. Unless POSIX and Yacc
+ portability matter to you, this is the preferred solution.
+
+ We suggest that you always enable the debug option so that debugging
+is always possible.
+
+ The trace facility outputs messages with macro calls of the form
+`YYFPRINTF (stderr, FORMAT, ARGS)' where FORMAT and ARGS are the usual
+`printf' format and variadic arguments. If you define `YYDEBUG' to a
+nonzero value but do not define `YYFPRINTF', `<stdio.h>' is
+automatically included and `YYFPRINTF' is defined to `fprintf'.
+
+ Once you have compiled the program with trace facilities, the way to
+request a trace is to store a nonzero value in the variable `yydebug'.
+You can do this by making the C code do it (in `main', perhaps), or you
+can alter the value with a C debugger.
+
+ Each step taken by the parser when `yydebug' is nonzero produces a
+line or two of trace information, written on `stderr'. The trace
+messages tell you these things:
+
+ * Each time the parser calls `yylex', what kind of token was read.
+
+ * Each time a token is shifted, the depth and complete contents of
+ the state stack (*note Parser States::).
+
+ * Each time a rule is reduced, which rule it is, and the complete
+ contents of the state stack afterward.
+
+ To make sense of this information, it helps to refer to the automaton
+description file (*note Understanding Your Parser: Understanding.).
+This file shows the meaning of each state in terms of positions in
+various rules, and also what each state will do with each possible
+input token. As you read the successive trace messages, you can see
+that the parser is functioning according to its specification in the
+listing file. Eventually you will arrive at the place where something
+undesirable happens, and you will see which parts of the grammar are to
+blame.
+
+ The parser implementation file is a C/C++/Java program and you can
+use debuggers on it, but it's not easy to interpret what it is doing.
+The parser function is a finite-state machine interpreter, and aside
+from the actions it executes the same code over and over. Only the
+values of variables show where in the grammar it is working.
+

+
+8.2.2 Enabling Debug Traces for `mfcalc'
+----------------------------------------
+
+The debugging information normally gives the token type of each token
+read, but not its semantic value. The `%printer' directive allows
+specify how semantic values are reported, see *note Printing Semantic
+Values: Printer Decl. For backward compatibility, Yacc like C parsers
+may also use the `YYPRINT' (*note The `YYPRINT' Macro: The YYPRINT
+Macro.), but its use is discouraged.
+
+ As a demonstration of `%printer', consider the multi-function
+calculator, `mfcalc' (*note Multi-function Calc::). To enable run-time
+traces, and semantic value reports, insert the following directives in
+its prologue:
+
+ /* Generate the parser description file. */
+ %verbose
+ /* Enable run-time traces (yydebug). */
+ %define parse.trace
+
+ /* Formatting semantic values. */
+ %printer { fprintf (yyoutput, "%s", $$->name); } VAR;
+ %printer { fprintf (yyoutput, "%s()", $$->name); } FNCT;
+ %printer { fprintf (yyoutput, "%g", $$); } <val>;
+
+ The `%define' directive instructs Bison to generate run-time trace
+support. Then, activation of these traces is controlled at run-time by
+the `yydebug' variable, which is disabled by default. Because these
+traces will refer to the "states" of the parser, it is helpful to ask
+for the creation of a description of that parser; this is the purpose
+of (admittedly ill-named) `%verbose' directive.
+
+ The set of `%printer' directives demonstrates how to format the
+semantic value in the traces. Note that the specification can be done
+either on the symbol type (e.g., `VAR' or `FNCT'), or on the type tag:
+since `<val>' is the type for both `NUM' and `exp', this printer will
+be used for them.
+
+ Here is a sample of the information provided by run-time traces.
+The traces are sent onto standard error.
+
+ $ echo 'sin(1-1)' | ./mfcalc -p
+ Starting parse
+ Entering state 0
+ Reducing stack by rule 1 (line 34):
+ -> $$ = nterm input ()
+ Stack now 0
+ Entering state 1
+
+This first batch shows a specific feature of this grammar: the first
+rule (which is in line 34 of `mfcalc.y' can be reduced without even
+having to look for the first token. The resulting left-hand symbol
+(`$$') is a valueless (`()') `input' non terminal (`nterm').
+
+ Then the parser calls the scanner.
+ Reading a token: Next token is token FNCT (sin())
+ Shifting token FNCT (sin())
+ Entering state 6
+
+That token (`token') is a function (`FNCT') whose value is `sin' as
+formatted per our `%printer' specification: `sin()'. The parser stores
+(`Shifting') that token, and others, until it can do something about it.

+
+8.2.3 The `YYPRINT' Macro
+-------------------------
+
+Before `%printer' support, semantic values could be displayed using the
+`YYPRINT' macro, which works only for terminal symbols and only with
+the `yacc.c' skeleton.
+
+ -- Macro: YYPRINT (STREAM, TOKEN, VALUE);
+ If you define `YYPRINT', it should take three arguments. The
+ parser will pass a standard I/O stream, the numeric code for the
+ token type, and the token value (from `yylval').
+
+ For `yacc.c' only. Obsoleted by `%printer'.
+
+ Here is an example of `YYPRINT' suitable for the multi-function
+calculator (*note Declarations for `mfcalc': Mfcalc Declarations.):
+
+ %{
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(File, Type, Value) \
+ print_token_value (File, Type, Value)
+ %}
+
+ ... %% ... %% ...
+
+ static void
+ print_token_value (FILE *file, int type, YYSTYPE value)
+ {
+ if (type == VAR)
+ fprintf (file, "%s", value.tptr->name);
+ else if (type == NUM)
+ fprintf (file, "%d", value.val);
+ }

+
+9 Invoking Bison
+****************
+
+The usual way to invoke Bison is as follows:
+
+ bison INFILE
+
+ Here INFILE is the grammar file name, which usually ends in `.y'.
+The parser implementation file's name is made by replacing the `.y'
+with `.tab.c' and removing any leading directory. Thus, the `bison
+foo.y' file name yields `foo.tab.c', and the `bison hack/foo.y' file
+name yields `foo.tab.c'. It's also possible, in case you are writing
+C++ code instead of C in your grammar file, to name it `foo.ypp' or
+`foo.y++'. Then, the output files will take an extension like the
+given one as input (respectively `foo.tab.cpp' and `foo.tab.c++'). This
+feature takes effect with all options that manipulate file names like
+`-o' or `-d'.
+
+ For example :
+
+ bison -d INFILE.YXX
+ will produce `infile.tab.cxx' and `infile.tab.hxx', and
+
+ bison -d -o OUTPUT.C++ INFILE.Y
+ will produce `output.c++' and `outfile.h++'.
+
+ For compatibility with POSIX, the standard Bison distribution also
+contains a shell script called `yacc' that invokes Bison with the `-y'
+option.
+
+* Menu:
+
+* Bison Options:: All the options described in detail,
+ in alphabetical order by short options.
+* Option Cross Key:: Alphabetical list of long options.
+* Yacc Library:: Yacc-compatible `yylex' and `main'.
+
+\1f
+File: bison.info, Node: Bison Options, Next: Option Cross Key, Up: Invocation
+
+9.1 Bison Options
+=================
+
+Bison supports both traditional single-letter options and mnemonic long
+option names. Long option names are indicated with `--' instead of
+`-'. Abbreviations for option names are allowed as long as they are
+unique. When a long option takes an argument, like `--file-prefix',
+connect the option name and the argument with `='.
+
+ Here is a list of options that can be used with Bison, alphabetized
+by short option. It is followed by a cross key alphabetized by long
+option.
+
+Operations modes:
+`-h'
+`--help'
+ Print a summary of the command-line options to Bison and exit.
+
+`-V'
+`--version'
+ Print the version number of Bison and exit.
+
+`--print-localedir'
+ Print the name of the directory containing locale-dependent data.
+
+`--print-datadir'
+ Print the name of the directory containing skeletons and XSLT.
+
+`-y'
+`--yacc'
+ Act more like the traditional Yacc command. This can cause
+ different diagnostics to be generated, and may change behavior in
+ other minor ways. Most importantly, imitate Yacc's output file
+ name conventions, so that the parser implementation file is called
+ `y.tab.c', and the other outputs are called `y.output' and
+ `y.tab.h'. Also, if generating a deterministic parser in C,
+ generate `#define' statements in addition to an `enum' to associate
+ token numbers with token names. Thus, the following shell script
+ can substitute for Yacc, and the Bison distribution contains such
+ a script for compatibility with POSIX:
+
+ #! /bin/sh
+ bison -y "$@"
+
+ The `-y'/`--yacc' option is intended for use with traditional Yacc
+ grammars. If your grammar uses a Bison extension like
+ `%glr-parser', Bison might not be Yacc-compatible even if this
+ option is specified.
+
+`-W [CATEGORY]'
+`--warnings[=CATEGORY]'
+ Output warnings falling in CATEGORY. CATEGORY can be one of:
+ `midrule-values'
+ Warn about mid-rule values that are set but not used within
+ any of the actions of the parent rule. For example, warn
+ about unused `$2' in:
+
+ exp: '1' { $$ = 1; } '+' exp { $$ = $1 + $4; };
+
+ Also warn about mid-rule values that are used but not set.
+ For example, warn about unset `$$' in the mid-rule action in:
+
+ exp: '1' { $1 = 1; } '+' exp { $$ = $2 + $4; };
+
+ These warnings are not enabled by default since they
+ sometimes prove to be false alarms in existing grammars
+ employing the Yacc constructs `$0' or `$-N' (where N is some
+ positive integer).
+
+ `yacc'
+ Incompatibilities with POSIX Yacc.
+
+ `conflicts-sr'
+ `conflicts-rr'
+ S/R and R/R conflicts. These warnings are enabled by
+ default. However, if the `%expect' or `%expect-rr' directive
+ is specified, an unexpected number of conflicts is an error,
+ and an expected number of conflicts is not reported, so `-W'
+ and `--warning' then have no effect on the conflict report.
+
+ `other'
+ All warnings not categorized above. These warnings are
+ enabled by default.
+
+ This category is provided merely for the sake of
+ completeness. Future releases of Bison may move warnings
+ from this category to new, more specific categories.
+
+ `all'
+ All the warnings.
+
+ `none'
+ Turn off all the warnings.
+
+ `error'
+ Treat warnings as errors.
+
+ A category can be turned off by prefixing its name with `no-'. For
+ instance, `-Wno-yacc' will hide the warnings about POSIX Yacc
+ incompatibilities.
+
+Tuning the parser:
+
+`-t'
+`--debug'
+ In the parser implementation file, define the macro `YYDEBUG' to 1
+ if it is not already defined, so that the debugging facilities are
+ compiled. *Note Tracing Your Parser: Tracing.
+
+`-D NAME[=VALUE]'
+`--define=NAME[=VALUE]'
+`-F NAME[=VALUE]'
+`--force-define=NAME[=VALUE]'
+ Each of these is equivalent to `%define NAME "VALUE"' (*note
+ %define Summary::) except that Bison processes multiple
+ definitions for the same NAME as follows:
+
+ * Bison quietly ignores all command-line definitions for NAME
+ except the last.
+
+ * If that command-line definition is specified by a `-D' or
+ `--define', Bison reports an error for any `%define'
+ definition for NAME.
+
+ * If that command-line definition is specified by a `-F' or
+ `--force-define' instead, Bison quietly ignores all `%define'
+ definitions for NAME.
+
+ * Otherwise, Bison reports an error if there are multiple
+ `%define' definitions for NAME.
+
+ You should avoid using `-F' and `--force-define' in your make
+ files unless you are confident that it is safe to quietly ignore
+ any conflicting `%define' that may be added to the grammar file.
+
+`-L LANGUAGE'
+`--language=LANGUAGE'
+ Specify the programming language for the generated parser, as if
+ `%language' was specified (*note Bison Declaration Summary: Decl
+ Summary.). Currently supported languages include C, C++, and Java.
+ LANGUAGE is case-insensitive.
+
+ This option is experimental and its effect may be modified in
+ future releases.
+
+`--locations'
+ Pretend that `%locations' was specified. *Note Decl Summary::.
+
+`-p PREFIX'
+`--name-prefix=PREFIX'
+ Pretend that `%name-prefix "PREFIX"' was specified (*note Decl
+ Summary::). Obsoleted by `-Dapi.prefix=PREFIX'. *Note Multiple
+ Parsers in the Same Program: Multiple Parsers.
+
+`-l'
+`--no-lines'
+ Don't put any `#line' preprocessor commands in the parser
+ implementation file. Ordinarily Bison puts them in the parser
+ implementation file so that the C compiler and debuggers will
+ associate errors with your source file, the grammar file. This
+ option causes them to associate errors with the parser
+ implementation file, treating it as an independent source file in
+ its own right.
+
+`-S FILE'
+`--skeleton=FILE'
+ Specify the skeleton to use, similar to `%skeleton' (*note Bison
+ Declaration Summary: Decl Summary.).
+
+ If FILE does not contain a `/', FILE is the name of a skeleton
+ file in the Bison installation directory. If it does, FILE is an
+ absolute file name or a file name relative to the current working
+ directory. This is similar to how most shells resolve commands.
+
+`-k'
+`--token-table'
+ Pretend that `%token-table' was specified. *Note Decl Summary::.
+
+Adjust the output:
+
+`--defines[=FILE]'
+ Pretend that `%defines' was specified, i.e., write an extra output
+ file containing macro definitions for the token type names defined
+ in the grammar, as well as a few other declarations. *Note Decl
+ Summary::.
+
+`-d'
+ This is the same as `--defines' except `-d' does not accept a FILE
+ argument since POSIX Yacc requires that `-d' can be bundled with
+ other short options.
+
+`-b FILE-PREFIX'
+`--file-prefix=PREFIX'
+ Pretend that `%file-prefix' was specified, i.e., specify prefix to
+ use for all Bison output file names. *Note Decl Summary::.
+
+`-r THINGS'
+`--report=THINGS'
+ Write an extra output file containing verbose description of the
+ comma separated list of THINGS among:
+
+ `state'
+ Description of the grammar, conflicts (resolved and
+ unresolved), and parser's automaton.
+
+ `lookahead'
+ Implies `state' and augments the description of the automaton
+ with each rule's lookahead set.
+
+ `itemset'
+ Implies `state' and augments the description of the automaton
+ with the full set of items for each state, instead of its
+ core only.
+
+`--report-file=FILE'
+ Specify the FILE for the verbose description.
+
+`-v'
+`--verbose'
+ Pretend that `%verbose' was specified, i.e., write an extra output
+ file containing verbose descriptions of the grammar and parser.
+ *Note Decl Summary::.
+
+`-o FILE'
+`--output=FILE'
+ Specify the FILE for the parser implementation file.
+
+ The other output files' names are constructed from FILE as
+ described under the `-v' and `-d' options.
+
+`-g [FILE]'
+`--graph[=FILE]'
+ Output a graphical representation of the parser's automaton
+ computed by Bison, in Graphviz (http://www.graphviz.org/) DOT
+ (http://www.graphviz.org/doc/info/lang.html) format. `FILE' is
+ optional. If omitted and the grammar file is `foo.y', the output

+9.3 Yacc Library
+================
+
+The Yacc library contains default implementations of the `yyerror' and
+`main' functions. These default implementations are normally not
+useful, but POSIX requires them. To use the Yacc library, link your
+program with the `-ly' option. Note that Bison's implementation of the
+Yacc library is distributed under the terms of the GNU General Public
+License (*note Copying::).
+
+ If you use the Yacc library's `yyerror' function, you should declare
+`yyerror' as follows:
+
+ int yyerror (char const *);
+
+ Bison ignores the `int' value returned by this `yyerror'. If you
+use the Yacc library's `main' function, your `yyparse' function should
+have the following type signature:
+
+ int yyparse (void);

+`%skeleton "lalr1.cc"', or the synonymous command-line option
+`--skeleton=lalr1.cc'. *Note Decl Summary::.
+
+ When run, `bison' will create several entities in the `yy' namespace. Use
+the `%define namespace' directive to change the namespace name, see
+*note namespace: %define Summary. The various classes are generated in
+the following files:
+
+`position.hh'
+`location.hh'
+ The definition of the classes `position' and `location', used for
+ location tracking. *Note C++ Location Values::.
+
+`stack.hh'
+ An auxiliary class `stack' used by the parser.
+
+`FILE.hh'
+`FILE.cc'
+ (Assuming the extension of the grammar file was `.yy'.) The
+ declaration and implementation of the C++ parser class. The
+ basename and extension of these two files follow the same rules as
+ with regular C parsers (*note Invocation::).
+
+ The header is _mandatory_; you must either pass `-d'/`--defines'
+ to `bison', or use the `%defines' directive.
+
+ All these files are documented using Doxygen; run `doxygen' for a
+complete and accurate documentation.

+10.1.2 C++ Semantic Values
+--------------------------
+
+The `%union' directive works as for C, see *note The Collection of
+Value Types: Union Decl. In particular it produces a genuine
+`union'(1), which have a few specific features in C++.
+ - The type `YYSTYPE' is defined but its use is discouraged: rather
+ you should refer to the parser's encapsulated type
+ `yy::parser::semantic_type'.
+
+ - Non POD (Plain Old Data) types cannot be used. C++ forbids any
+ instance of classes with constructors in unions: only _pointers_
+ to such objects are allowed.
+
+ Because objects have to be stored via pointers, memory is not
+reclaimed automatically: using the `%destructor' directive is the only
+means to avoid leaks. *Note Freeing Discarded Symbols: Destructor Decl.
+
+ ---------- Footnotes ----------
+
+ (1) In the future techniques to allow complex types within
+pseudo-unions (similar to Boost variants) might be implemented to
+alleviate these issues.

+10.1.3 C++ Location Values
+--------------------------
+
+When the directive `%locations' is used, the C++ parser supports
+location tracking, see *note Tracking Locations::. Two auxiliary
+classes define a `position', a single point in a file, and a
+`location', a range composed of a pair of `position's (possibly
+spanning several files).
+
+ In this section `uint' is an abbreviation for `unsigned int': in
+genuine code only the latter is used.

+10.1.4 C++ Parser Interface
+---------------------------
+
+The output files `OUTPUT.hh' and `OUTPUT.cc' declare and define the
+parser class in the namespace `yy'. The class name defaults to
+`parser', but may be changed using `%define parser_class_name "NAME"'.
+The interface of this class is detailed below. It can be extended
+using the `%parse-param' feature: its semantics is slightly changed
+since it describes an additional member of the parser class, and an
+additional argument for its constructor.
+
+ -- Type of parser: semantic_type
+ -- Type of parser: location_type
+ The types for semantics value and locations.
+
+ -- Type of parser: token
+ A structure that contains (only) the `yytokentype' enumeration,
+ which defines the tokens. To refer to the token `FOO', use
+ `yy::parser::token::FOO'. The scanner can use `typedef
+ yy::parser::token token;' to "import" the token enumeration (*note
+ Calc++ Scanner::).
+
+ -- Method on parser: parser (TYPE1 ARG1, ...)

+ -- Method on parser: void set_debug_level (debug_level L)
+ Get or set the tracing level. Currently its value is either 0, no
+ trace, or nonzero, full tracing.
+
+ -- Method on parser: void error (const location_type& L, const
+ std::string& M)
+ The definition for this member function must be supplied by the
+ user: the parser uses it to report a parser error occurring at L,
+ described by M.

+10.1.5 C++ Scanner Interface
+----------------------------
+
+The parser invokes the scanner by calling `yylex'. Contrary to C
+parsers, C++ parsers are always pure: there is no point in using the
+`%define api.pure' directive. Therefore the interface is as follows.
+
+ -- Method on parser: int yylex (semantic_type* YYLVAL, location_type*
+ YYLLOC, TYPE1 ARG1, ...)
+ Return the next token. Its type is the return value, its semantic
+ value and location being YYLVAL and YYLLOC. Invocations of
+ `%lex-param {TYPE1 ARG1}' yield additional arguments.

+
+This section demonstrates the use of a C++ parser with a simple but
+complete example. This example should be available on your system,
+ready to compile, in the directory "../bison/examples/calc++". It
+focuses on the use of Bison, therefore the design of the various C++
+classes is very naive: no accessors, no encapsulation of members etc.
+We will use a Lex scanner, and more precisely, a Flex scanner, to
+demonstrate the various interaction. A hand written scanner is
+actually easier to interface with.

+.................................
+
+Of course the grammar is dedicated to arithmetics, a single expression,
+possibly preceded by variable assignments. An environment containing
+possibly predefined variables such as `one' and `two', is exchanged
+with the parser. An example of valid input follows.

+File: bison.info, Node: Calc++ Parsing Driver, Next: Calc++ Parser, Prev: Calc++ --- C++ Calculator, Up: A Complete C++ Example
+
+10.1.6.2 Calc++ Parsing Driver
+..............................
+
+To support a pure interface with the parser (and the scanner) the
+technique of the "parsing context" is convenient: a structure
+containing all the data to exchange. Since, in addition to simply
+launch the parsing, there are several auxiliary tasks to execute (open
+the file for parsing, instantiate the parser etc.), we recommend
+transforming the simple parsing context structure into a fully blown
+"parsing driver" class.
+
+ The declaration of this driver class, `calc++-driver.hh', is as
+follows. The first part includes the CPP guard and imports the
+required standard library components, and the declaration of the parser
+class.
+
+ #ifndef CALCXX_DRIVER_HH
+ # define CALCXX_DRIVER_HH
+ # include <string>
+ # include <map>
+ # include "calc++-parser.hh"
+
+Then comes the declaration of the scanning function. Flex expects the
+signature of `yylex' to be defined in the macro `YY_DECL', and the C++
+parser expects it to be declared. We can factor both as follows.
+
+ // Tell Flex the lexer's prototype ...
+ # define YY_DECL \
+ yy::calcxx_parser::token_type \
+ yylex (yy::calcxx_parser::semantic_type* yylval, \
+ yy::calcxx_parser::location_type* yylloc, \
+ calcxx_driver& driver)
+ // ... and declare it for the parser's sake.
+ YY_DECL;
+
+The `calcxx_driver' class is then declared with its most obvious
+members.
+
+ // Conducting the whole scanning and parsing of Calc++.
+ class calcxx_driver
+ {
+ public:
+ calcxx_driver ();
+ virtual ~calcxx_driver ();
+
+ std::map<std::string, int> variables;
+
+ int result;
+
+To encapsulate the coordination with the Flex scanner, it is useful to
+have two members function to open and close the scanning phase.
+
+ // Handling the scanner.
+ void scan_begin ();
+ void scan_end ();
+ bool trace_scanning;
+
+Similarly for the parser itself.
+
+ // Run the parser. Return 0 on success.
+ int parse (const std::string& f);
+ std::string file;
+ bool trace_parsing;
+
+To demonstrate pure handling of parse errors, instead of simply dumping
+them on the standard error output, we will pass them to the compiler
+driver using the following two member functions. Finally, we close the
+class declaration and CPP guard.
+
+ // Error handling.
+ void error (const yy::location& l, const std::string& m);
+ void error (const std::string& m);
+ };
+ #endif // ! CALCXX_DRIVER_HH
+
+ The implementation of the driver is straightforward. The `parse'
+member function deserves some attention. The `error' functions are
+simple stubs, they should actually register the located error messages
+and set error state.
+
+ #include "calc++-driver.hh"
+ #include "calc++-parser.hh"

+ calcxx_driver::calcxx_driver ()

+
+10.1.6.3 Calc++ Parser
+......................
+
+The grammar file `calc++-parser.yy' starts by asking for the C++
+deterministic parser skeleton, the creation of the parser header file,
+and specifies the name of the parser class. Because the C++ skeleton
+changed several times, it is safer to require the version you designed
+the grammar for.
+
+ %skeleton "lalr1.cc" /* -*- C++ -*- */
+ %require "2.6"
+ %defines
+ %define parser_class_name "calcxx_parser"
+
+Then come the declarations/inclusions needed to define the `%union'.
+Because the parser uses the parsing driver and reciprocally, both
+cannot include the header of the other. Because the driver's header
+needs detailed knowledge about the parser class (in particular its
+inner types), it is the parser's header which will simply use a forward
+declaration of the driver. *Note %code Summary::.
+
+ %code requires {
+ # include <string>
+ class calcxx_driver;
+ }
+
+The driver is passed by reference to the parser and to the scanner.
+This provides a simple but effective pure interface, not relying on
+global variables.
+
+ // The parsing context.
+ %parse-param { calcxx_driver& driver }
+ %lex-param { calcxx_driver& driver }
+
+Then we request the location tracking feature, and initialize the first
+location's file name. Afterward new locations are computed relatively
+to the previous locations: the file name will be automatically
+propagated.
+
+ %locations
+ %initial-action
+ {
+ // Initialize the initial location.
+ @$.begin.filename = @$.end.filename = &driver.file;
+ };
+
+Use the two following directives to enable parser tracing and verbose
+error messages. However, verbose error messages can contain incorrect
+information (*note LAC::).
+
+ %debug
+ %error-verbose
+
+Semantic values cannot use "real" objects, but only pointers to them.
+
+ // Symbols.
+ %union
+ {
+ int ival;
+ std::string *sval;
+ };
+
+The code between `%code {' and `}' is output in the `*.cc' file; it
+needs detailed knowledge about the driver.
+
+ %code {
+ # include "calc++-driver.hh"
+ }
+
+The token numbered as 0 corresponds to end of file; the following line
+allows for nicer error messages referring to "end of file" instead of
+"$end". Similarly user friendly named are provided for each symbol.
+Note that the tokens names are prefixed by `TOKEN_' to avoid name
+clashes.
+
+ %token END 0 "end of file"
+ %token ASSIGN ":="
+ %token <sval> IDENTIFIER "identifier"
+ %token <ival> NUMBER "number"
+ %type <ival> exp
+
+To enable memory deallocation during error recovery, use `%destructor'.
+
+ %printer { yyoutput << *$$; } "identifier"
+ %destructor { delete $$; } "identifier"
+
+ %printer { yyoutput << $$; } <ival>
+
+The grammar itself is straightforward.
+
+ %%
+ %start unit;
+ unit: assignments exp { driver.result = $2; };
+
+ assignments:
+ /* Nothing. */ {}
+ | assignments assignment {};
+
+ assignment:
+ "identifier" ":=" exp
+ { driver.variables[*$1] = $3; delete $1; };
+
+ %left '+' '-';
+ %left '*' '/';
+ exp: exp '+' exp { $$ = $1 + $3; }
+ | exp '-' exp { $$ = $1 - $3; }
+ | exp '*' exp { $$ = $1 * $3; }
+ | exp '/' exp { $$ = $1 / $3; }
+ | "identifier" { $$ = driver.variables[*$1]; delete $1; }
+ | "number" { $$ = $1; };
+ %%
+
+Finally the `error' member function registers the errors to the driver.
+
+ void
+ yy::calcxx_parser::error (const yy::calcxx_parser::location_type& l,
+ const std::string& m)
+ {
+ driver.error (l, m);

+10.1.6.4 Calc++ Scanner

+ # undef yywrap
+ # define yywrap() 1
+
+ /* By default yylex returns int, we use token_type.
+ Unfortunately yyterminate by default returns 0, which is
+ not of token_type. */
+ #define yyterminate() return token::END
+ %}
+
+Because there is no `#include'-like feature we don't need `yywrap', we
+don't need `unput' either, and we parse an actual file, this is not an
+interactive session with the user. Finally we enable the scanner
+tracing features.
+
+ %option noyywrap nounput batch debug
+
+Abbreviations allow for more readable rules.
+
+ id [a-zA-Z][a-zA-Z_0-9]*
+ int [0-9]+
+ blank [ \t]
+
+The following paragraph suffices to track locations accurately. Each
+time `yylex' is invoked, the begin position is moved onto the end
+position. Then when a pattern is matched, the end position is advanced
+of its width. In case it matched ends of lines, the end cursor is
+adjusted, and each time blanks are matched, the begin cursor is moved
+onto the end cursor to effectively ignore the blanks preceding tokens.
+Comments would be treated equally.
+
+ %{
+ # define YY_USER_ACTION yylloc->columns (yyleng);
+ %}
+ %%
+ %{
+ yylloc->step ();
+ %}
+ {blank}+ yylloc->step ();
+ [\n]+ yylloc->lines (yyleng); yylloc->step ();
+
+The rules are simple, just note the use of the driver to report errors.
+It is convenient to use a typedef to shorten
+`yy::calcxx_parser::token::identifier' into `token::identifier' for
+instance.
+
+ %{
+ typedef yy::calcxx_parser::token token;
+ %}
+ /* Convert ints to the actual type of tokens. */
+ [-+*/] return yy::calcxx_parser::token_type (yytext[0]);
+ ":=" return token::ASSIGN;
+ {int} {
+ errno = 0;
+ long n = strtol (yytext, NULL, 10);
+ if (! (INT_MIN <= n && n <= INT_MAX && errno != ERANGE))
+ driver.error (*yylloc, "integer is out of range");
+ yylval->ival = n;
+ return token::NUMBER;
+ }
+ {id} yylval->sval = new std::string (yytext); return token::IDENTIFIER;
+ . driver.error (*yylloc, "invalid character");
+ %%
+
+Finally, because the scanner related driver's member function depend on
+the scanner's data, it is simpler to implement them in this file.
+
+ void
+ calcxx_driver::scan_begin ()

+ yy_flex_debug = trace_scanning;

+File: bison.info, Node: Java Bison Interface, Next: Java Semantic Values, Up: Java Parsers
+
+10.2.1 Java Bison Interface
+---------------------------
+
+(The current Java interface is experimental and may evolve. More user
+feedback will help to stabilize it.)
+
+ The Java parser skeletons are selected using the `%language "Java"'
+directive or the `-L java'/`--language=java' option.
+
+ When generating a Java parser, `bison BASENAME.y' will create a
+single Java source file named `BASENAME.java' containing the parser
+implementation. Using a grammar file without a `.y' suffix is
+currently broken. The basename of the parser implementation file can
+be changed by the `%file-prefix' directive or the `-p'/`--name-prefix'
+option. The entire parser implementation file name can be changed by
+the `%output' directive or the `-o'/`--output' option. The parser
+implementation file contains a single class for the parser.
+
+ You can create documentation for generated parsers using Javadoc.
+
+ Contrary to C parsers, Java parsers do not use global variables; the
+state of the parser is always local to an instance of the parser class.
+Therefore, all Java parsers are "pure", and the `%pure-parser' and
+`%define api.pure' directives does not do anything when used in Java.
+
+ Push parsers are currently unsupported in Java and `%define
+api.push-pull' have no effect.
+
+ GLR parsers are currently unsupported in Java. Do not use the
+`glr-parser' directive.
+
+ No header file can be generated for Java parsers. Do not use the
+`%defines' directive or the `-d'/`--defines' options.
+
+ Currently, support for debugging and verbose errors are always
+compiled in. Thus the `%debug' and `%token-table' directives and the
+`-t'/`--debug' and `-k'/`--token-table' options have no effect. This
+may change in the future to eliminate unused code in the generated
+parser, so use `%debug' and `%verbose-error' explicitly if needed.
+Also, in the future the `%token-table' directive might enable a public
+interface to access the token names and codes.
+
+\1f
+File: bison.info, Node: Java Semantic Values, Next: Java Location Values, Prev: Java Bison Interface, Up: Java Parsers
+
+10.2.2 Java Semantic Values
+---------------------------
+
+There is no `%union' directive in Java parsers. Instead, the semantic
+values' types (class names) should be specified in the `%type' or
+`%token' directive:
+
+ %type <Expression> expr assignment_expr term factor
+ %type <Integer> number
+
+ By default, the semantic stack is declared to have `Object' members,
+which means that the class types you specify can be of any class. To
+improve the type safety of the parser, you can declare the common
+superclass of all the semantic values using the `%define stype'
+directive. For example, after the following declaration:
+
+ %define stype "ASTNode"
+
+any `%type' or `%token' specifying a semantic type which is not a
+subclass of ASTNode, will cause a compile-time error.
+
+ Types used in the directives may be qualified with a package name.
+Primitive data types are accepted for Java version 1.5 or later. Note
+that in this case the autoboxing feature of Java 1.5 will be used.
+Generic types may not be used; this is due to a limitation in the
+implementation of Bison, and may change in future releases.
+
+ Java parsers do not support `%destructor', since the language adopts
+garbage collection. The parser will try to hold references to semantic
+values for as little time as needed.
+
+ Java parsers do not support `%printer', as `toString()' can be used
+to print the semantic values. This however may change (in a
+backwards-compatible way) in future versions of Bison.

+
+10.2.3 Java Location Values
+---------------------------
+
+When the directive `%locations' is used, the Java parser supports
+location tracking, see *note Tracking Locations::. An auxiliary
+user-defined class defines a "position", a single point in a file;
+Bison itself defines a class representing a "location", a range
+composed of a pair of positions (possibly spanning several files). The
+location class is an inner class of the parser; the name is `Location'
+by default, and may also be renamed using `%define location_type
+"CLASS-NAME"'.
+
+ The location class treats the position as a completely opaque value.
+By default, the class name is `Position', but this can be changed with
+`%define position_type "CLASS-NAME"'. This class must be supplied by
+the user.
+
+ -- Instance Variable of Location: Position begin
+ -- Instance Variable of Location: Position end
+ The first, inclusive, position of the range, and the first beyond.
+
+ -- Constructor on Location: Location (Position LOC)
+ Create a `Location' denoting an empty range located at a given
+ point.
+
+ -- Constructor on Location: Location (Position BEGIN, Position END)
+ Create a `Location' from the endpoints of the range.
+
+ -- Method on Location: String toString ()
+ Prints the range represented by the location. For this to work
+ properly, the position class should override the `equals' and
+ `toString' methods appropriately.
+

+File: bison.info, Node: Java Parser Interface, Next: Java Scanner Interface, Prev: Java Location Values, Up: Java Parsers
+
+10.2.4 Java Parser Interface
+----------------------------
+
+The name of the generated parser class defaults to `YYParser'. The
+`YY' prefix may be changed using the `%name-prefix' directive or the
+`-p'/`--name-prefix' option. Alternatively, use `%define
+parser_class_name "NAME"' to give a custom name to the class. The
+interface of this class is detailed below.
+
+ By default, the parser class has package visibility. A declaration
+`%define public' will change to public visibility. Remember that,
+according to the Java language specification, the name of the `.java'
+file should match the name of the class in this case. Similarly, you
+can use `abstract', `final' and `strictfp' with the `%define'
+declaration to add other modifiers to the parser class.
+
+ The Java package name of the parser class can be specified using the
+`%define package' directive. The superclass and the implemented
+interfaces of the parser class can be specified with the `%define
+extends' and `%define implements' directives.
+
+ The parser class defines an inner class, `Location', that is used
+for location tracking (see *note Java Location Values::), and a inner
+interface, `Lexer' (see *note Java Scanner Interface::). Other than
+these inner class/interface, and the members described in the interface
+below, all the other members and fields are preceded with a `yy' or
+`YY' prefix to avoid clashes with user code.
+
+ The parser class can be extended using the `%parse-param' directive.
+Each occurrence of the directive will add a `protected final' field to
+the parser class, and an argument to its constructor, which initialize
+them automatically.
+
+ Token names defined by `%token' and the predefined `EOF' token name
+are added as constant fields to the parser class.
+
+ -- Constructor on YYParser: YYParser (LEX_PARAM, ..., PARSE_PARAM,
+ ...)
+ Build a new parser object with embedded `%code lexer'. There are
+ no parameters, unless `%parse-param's and/or `%lex-param's are
+ used.
+
+ -- Constructor on YYParser: YYParser (Lexer LEXER, PARSE_PARAM, ...)
+ Build a new parser object using the specified scanner. There are
+ no additional parameters unless `%parse-param's are used.
+
+ If the scanner is defined by `%code lexer', this constructor is
+ declared `protected' and is called automatically with a scanner
+ created with the correct `%lex-param's.
+
+ -- Method on YYParser: boolean parse ()
+ Run the syntactic analysis, and return `true' on success, `false'
+ otherwise.
+
+ -- Method on YYParser: boolean recovering ()
+ During the syntactic analysis, return `true' if recovering from a
+ syntax error. *Note Error Recovery::.
+
+ -- Method on YYParser: java.io.PrintStream getDebugStream ()
+ -- Method on YYParser: void setDebugStream (java.io.printStream O)
+ Get or set the stream used for tracing the parsing. It defaults to
+ `System.err'.
+
+ -- Method on YYParser: int getDebugLevel ()
+ -- Method on YYParser: void setDebugLevel (int L)
+ Get or set the tracing level. Currently its value is either 0, no
+ trace, or nonzero, full tracing.

+
+10.2.5 Java Scanner Interface
+-----------------------------
+
+There are two possible ways to interface a Bison-generated Java parser
+with a scanner: the scanner may be defined by `%code lexer', or defined
+elsewhere. In either case, the scanner has to implement the `Lexer'
+inner interface of the parser class.
+
+ In the first case, the body of the scanner class is placed in `%code
+lexer' blocks. If you want to pass parameters from the parser
+constructor to the scanner constructor, specify them with `%lex-param';
+they are passed before `%parse-param's to the constructor.
+
+ In the second case, the scanner has to implement the `Lexer'
+interface, which is defined within the parser class (e.g.,
+`YYParser.Lexer'). The constructor of the parser object will then
+accept an object implementing the interface; `%lex-param' is not used
+in this case.
+
+ In both cases, the scanner has to implement the following methods.
+
+ -- Method on Lexer: void yyerror (Location LOC, String MSG)
+ This method is defined by the user to emit an error message. The
+ first parameter is omitted if location tracking is not active.
+ Its type can be changed using `%define location_type "CLASS-NAME".'
+
+ -- Method on Lexer: int yylex ()
+ Return the next token. Its type is the return value, its semantic
+ value and location are saved and returned by the their methods in
+ the interface.
+
+ Use `%define lex_throws' to specify any uncaught exceptions.
+ Default is `java.io.IOException'.
+
+ -- Method on Lexer: Position getStartPos ()
+ -- Method on Lexer: Position getEndPos ()
+ Return respectively the first position of the last token that
+ `yylex' returned, and the first position beyond it. These methods
+ are not needed unless location tracking is active.
+
+ The return type can be changed using `%define position_type
+ "CLASS-NAME".'
+
+ -- Method on Lexer: Object getLVal ()
+ Return the semantic value of the last token that yylex returned.
+
+ The return type can be changed using `%define stype "CLASS-NAME".'

+
+10.2.6 Special Features for Use in Java Actions
+-----------------------------------------------
+
+The following special constructs can be uses in Java actions. Other
+analogous C action features are currently unavailable for Java.
+
+ Use `%define throws' to specify any uncaught exceptions from parser
+actions, and initial actions specified by `%initial-action'.
+
+ -- Variable: $N
+ The semantic value for the Nth component of the current rule.
+ This may not be assigned to. *Note Java Semantic Values::.
+
+ -- Variable: $<TYPEALT>N
+ Like `$N' but specifies a alternative type TYPEALT. *Note Java
+ Semantic Values::.
+
+ -- Variable: $$
+ The semantic value for the grouping made by the current rule. As a
+ value, this is in the base type (`Object' or as specified by
+ `%define stype') as in not cast to the declared subtype because
+ casts are not allowed on the left-hand side of Java assignments.
+ Use an explicit Java cast if the correct subtype is needed. *Note
+ Java Semantic Values::.
+
+ -- Variable: $<TYPEALT>$
+ Same as `$$' since Java always allow assigning to the base type.
+ Perhaps we should use this and `$<>$' for the value and `$$' for
+ setting the value but there is currently no easy way to distinguish
+ these constructs. *Note Java Semantic Values::.
+
+ -- Variable: @N
+ The location information of the Nth component of the current rule.
+ This may not be assigned to. *Note Java Location Values::.
+
+ -- Variable: @$
+ The location information of the grouping made by the current rule.
+ *Note Java Location Values::.
+
+ -- Statement: return YYABORT `;'
+ Return immediately from the parser, indicating failure. *Note
+ Java Parser Interface::.
+
+ -- Statement: return YYACCEPT `;'
+ Return immediately from the parser, indicating success. *Note
+ Java Parser Interface::.
+
+ -- Statement: return YYERROR `;'
+ Start error recovery (without printing an error message). *Note
+ Error Recovery::.
+
+ -- Function: boolean recovering ()
+ Return whether error recovery is being done. In this state, the
+ parser reads token until it reaches a known state, and then
+ restarts normal operation. *Note Error Recovery::.
+
+ -- Function: protected void yyerror (String msg)
+ -- Function: protected void yyerror (Position pos, String msg)
+ -- Function: protected void yyerror (Location loc, String msg)
+ Print an error message using the `yyerror' method of the scanner
+ instance in use.

+
+10.2.7 Differences between C/C++ and Java Grammars
+--------------------------------------------------
+
+The different structure of the Java language forces several differences
+between C/C++ grammars, and grammars designed for Java parsers. This
+section summarizes these differences.
+
+ * Java lacks a preprocessor, so the `YYERROR', `YYACCEPT', `YYABORT'
+ symbols (*note Table of Symbols::) cannot obviously be macros.
+ Instead, they should be preceded by `return' when they appear in
+ an action. The actual definition of these symbols is opaque to
+ the Bison grammar, and it might change in the future. The only
+ meaningful operation that you can do, is to return them. *Note
+ Java Action Features::.
+
+ Note that of these three symbols, only `YYACCEPT' and `YYABORT'
+ will cause a return from the `yyparse' method(1).
+
+ * Java lacks unions, so `%union' has no effect. Instead, semantic
+ values have a common base type: `Object' or as specified by
+ `%define stype'. Angle brackets on `%token', `type', `$N' and
+ `$$' specify subtypes rather than fields of an union. The type of
+ `$$', even with angle brackets, is the base type since Java casts
+ are not allow on the left-hand side of assignments. Also, `$N'
+ and `@N' are not allowed on the left-hand side of assignments.
+ *Note Java Semantic Values::, and *note Java Action Features::.
+
+ * The prologue declarations have a different meaning than in C/C++
+ code.
+ `%code imports'
+ blocks are placed at the beginning of the Java source code.
+ They may include copyright notices. For a `package'
+ declarations, it is suggested to use `%define package'
+ instead.
+
+ unqualified `%code'
+ blocks are placed inside the parser class.
+
+ `%code lexer'
+ blocks, if specified, should include the implementation of the
+ scanner. If there is no such block, the scanner can be any
+ class that implements the appropriate interface (*note Java
+ Scanner Interface::).
+
+ Other `%code' blocks are not supported in Java parsers. In
+ particular, `%{ ... %}' blocks should not be used and may give an
+ error in future versions of Bison.
+
+ The epilogue has the same meaning as in C/C++ code and it can be
+ used to define other classes used by the parser _outside_ the
+ parser class.
+
+ ---------- Footnotes ----------
+
+ (1) Java parsers include the actions in a separate method than
+`yyparse' in order to have an intuitive syntax that corresponds to
+these C macros.

+11.1 Memory Exhausted

+ What can I do?
+
+ This question is already addressed elsewhere, see *note Recursive
+Rules: Recursion.
+
+\1f
+File: bison.info, Node: How Can I Reset the Parser, Next: Strings are Destroyed, Prev: Memory Exhausted, Up: FAQ
+
+11.2 How Can I Reset the Parser
+===============================
+
+The following phenomenon has several symptoms, resulting in the
+following typical questions:
+
+ I invoke `yyparse' several times, and on correct input it works
+ properly; but when a parse error is found, all the other calls fail
+ too. How can I reset the error flag of `yyparse'?
+
+or
+
+ My parser includes support for an `#include'-like feature, in
+ which case I run `yyparse' from `yyparse'. This fails although I
+ did specify `%define api.pure'.
+
+ These problems typically come not from Bison itself, but from
+Lex-generated scanners. Because these scanners use large buffers for
+speed, they might not notice a change of input file. As a
+demonstration, consider the following source file, `first-line.l':
+
+ %{
+ #include <stdio.h>
+ #include <stdlib.h>
+ %}
+ %%
+ .*\n ECHO; return 1;
+ %%
+ int
+ yyparse (char const *file)
+ {
+ yyin = fopen (file, "r");
+ if (!yyin)
+ {
+ perror ("fopen");
+ exit (EXIT_FAILURE);
+ }
+ /* One token only. */
+ yylex ();
+ if (fclose (yyin) != 0)
+ {
+ perror ("fclose");
+ exit (EXIT_FAILURE);
+ }
+ return 0;
+ }
+
+ int
+ main (void)
+ {
+ yyparse ("input");
+ yyparse ("input");
+ return 0;
+ }
+
+If the file `input' contains
+
+ input:1: Hello,
+ input:2: World!
+
+then instead of getting the first line twice, you get:
+
+ $ flex -ofirst-line.c first-line.l
+ $ gcc -ofirst-line first-line.c -ll
+ $ ./first-line
+ input:1: Hello,
+ input:2: World!
+
+ Therefore, whenever you change `yyin', you must tell the
+Lex-generated scanner to discard its current buffer and switch to the
+new one. This depends upon your implementation of Lex; see its
+documentation for more. For Flex, it suffices to call
+`YY_FLUSH_BUFFER' after each change to `yyin'. If your Flex-generated
+scanner needs to read from several input streams to handle features
+like include files, you might consider using Flex functions like
+`yy_switch_to_buffer' that manipulate multiple input buffers.
+
+ If your Flex-generated scanner uses start conditions (*note Start
+conditions: (flex)Start conditions.), you might also want to reset the
+scanner's state, i.e., go back to the initial start condition, through
+a call to `BEGIN (0)'.
+
+\1f
+File: bison.info, Node: Strings are Destroyed, Next: Implementing Gotos/Loops, Prev: How Can I Reset the Parser, Up: FAQ
+
+11.3 Strings are Destroyed
+==========================
+
+ My parser seems to destroy old strings, or maybe it loses track of
+ them. Instead of reporting `"foo", "bar"', it reports `"bar",
+ "bar"', or even `"foo\nbar", "bar"'.
+
+ This error is probably the single most frequent "bug report" sent to
+Bison lists, but is only concerned with a misunderstanding of the role
+of the scanner. Consider the following Lex code:
+
+ %{
+ #include <stdio.h>
+ char *yylval = NULL;
+ %}
+ %%
+ .* yylval = yytext; return 1;
+ \n /* IGNORE */
+ %%
+ int
+ main ()
+ {
+ /* Similar to using $1, $2 in a Bison action. */
+ char *fst = (yylex (), yylval);
+ char *snd = (yylex (), yylval);
+ printf ("\"%s\", \"%s\"\n", fst, snd);
+ return 0;
+ }
+
+ If you compile and run this code, you get:
+
+ $ flex -osplit-lines.c split-lines.l
+ $ gcc -osplit-lines split-lines.c -ll
+ $ printf 'one\ntwo\n' | ./split-lines
+ "one
+ two", "two"
+
+this is because `yytext' is a buffer provided for _reading_ in the
+action, but if you want to keep it, you have to duplicate it (e.g.,
+using `strdup'). Note that the output may depend on how your
+implementation of Lex handles `yytext'. For instance, when given the
+Lex compatibility option `-l' (which triggers the option `%array') Flex
+generates a different behavior:
+
+ $ flex -l -osplit-lines.c split-lines.l
+ $ gcc -osplit-lines split-lines.c -ll
+ $ printf 'one\ntwo\n' | ./split-lines
+ "two", "two"
+

+
+11.4 Implementing Gotos/Loops
+=============================
+
+ My simple calculator supports variables, assignments, and
+ functions, but how can I implement gotos, or loops?
+
+ Although very pedagogical, the examples included in the document blur
+the distinction to make between the parser--whose job is to recover the
+structure of a text and to transmit it to subsequent modules of the
+program--and the processing (such as the execution) of this structure.
+This works well with so called straight line programs, i.e., precisely
+those that have a straightforward execution model: execute simple
+instructions one after the others.
+
+ If you want a richer model, you will probably need to use the parser
+to construct a tree that does represent the structure it has recovered;
+this tree is usually called the "abstract syntax tree", or "AST" for
+short. Then, walking through this tree, traversing it in various ways,
+will enable treatments such as its execution or its translation, which
+will result in an interpreter or a compiler.
+
+ This topic is way beyond the scope of this manual, and the reader is
+invited to consult the dedicated literature.
+
+\1f
+File: bison.info, Node: Multiple start-symbols, Next: Secure? Conform?, Prev: Implementing Gotos/Loops, Up: FAQ
+
+11.5 Multiple start-symbols
+===========================
+
+ I have several closely related grammars, and I would like to share
+ their implementations. In fact, I could use a single grammar but
+ with multiple entry points.
+
+ Bison does not support multiple start-symbols, but there is a very
+simple means to simulate them. If `foo' and `bar' are the two pseudo
+start-symbols, then introduce two new tokens, say `START_FOO' and
+`START_BAR', and use them as switches from the real start-symbol:
+
+ %token START_FOO START_BAR;
+ %start start;
+ start:
+ START_FOO foo
+ | START_BAR bar;
+
+ These tokens prevents the introduction of new conflicts. As far as
+the parser goes, that is all that is needed.
+
+ Now the difficult part is ensuring that the scanner will send these
+tokens first. If your scanner is hand-written, that should be
+straightforward. If your scanner is generated by Lex, them there is
+simple means to do it: recall that anything between `%{ ... %}' after
+the first `%%' is copied verbatim in the top of the generated `yylex'
+function. Make sure a variable `start_token' is available in the
+scanner (e.g., a global variable or using `%lex-param' etc.), and use
+the following:
+
+ /* Prologue. */
+ %%
+ %{
+ if (start_token)
+ {
+ int t = start_token;
+ start_token = 0;
+ return t;
+ }
+ %}
+ /* The rules. */

+
+11.9 Bug Reports
+================
+
+ I found a bug. What should I include in the bug report?
+
+ Before you send a bug report, make sure you are using the latest
+version. Check `ftp://ftp.gnu.org/pub/gnu/bison/' or one of its
+mirrors. Be sure to include the version number in your bug report. If
+the bug is present in the latest version but not in a previous version,
+try to determine the most recent version which did not contain the bug.
+
+ If the bug is parser-related, you should include the smallest grammar
+you can which demonstrates the bug. The grammar file should also be
+complete (i.e., I should be able to run it through Bison without having
+to edit or add anything). The smaller and simpler the grammar, the
+easier it will be to fix the bug.

+====================
+
+ Will Bison ever have C++ and Java support? How about INSERT YOUR
+ FAVORITE LANGUAGE HERE?
+
+ C++ and Java support is there now, and is documented. We'd love to
+add other languages; contributions are welcome.

+
+11.11 Beta Testing
+==================
+
+ What is involved in being a beta tester?
+
+ It's not terribly involved. Basically, you would download a test
+release, compile it, and use it to build and run a parser or two. After
+that, you would submit either a bug report or a message saying that
+everything is okay. It is important to report successes as well as
+failures because test releases eventually become mainstream releases,
+but only if they are adequately tested. If no one tests, development is
+essentially halted.
+
+ Beta testers are particularly needed for operating systems to which
+the developers do not have easy access. They currently have easy
+access to recent GNU/Linux and Solaris versions. Reports about other
+operating systems are especially welcome.

+
+ -- Symbol: $end
+ The predefined token marking the end of the token stream. It
+ cannot be used in the grammar.
+
+ -- Symbol: error
+ A token name reserved for error recovery. This token may be used
+ in grammar rules so as to allow the Bison parser to recognize an
+ error in the grammar without halting the process. In effect, a
+ sentence containing an error may be recognized as valid. On a
+ syntax error, the token `error' becomes the current lookahead

+ Parsers in the Same Program: Multiple Parsers.).
+
+ Rename the external symbols (variables and functions) used in the
+ parser so that they start with PREFIX instead of `yy'. Contrary to
+ `api.prefix', do no rename types and macros.
+
+ The precise list of symbols renamed in C parsers is `yyparse',
+ `yylex', `yyerror', `yynerrs', `yylval', `yychar', `yydebug', and
+ (if locations are used) `yylloc'. If you use a push parser,
+ `yypush_parse', `yypull_parse', `yypstate', `yypstate_new' and

+ Parser Function.
+
+ -- Directive: %prec
+ Bison declaration to assign a precedence to a specific rule.
+ *Note Context-Dependent Precedence: Contextual Precedence.
+
+ -- Directive: %pure-parser
+ Deprecated version of `%define api.pure' (*note api.pure: %define
+ Summary.), for which Bison is more careful to warn about

+
+ -- Symbol: $undefined
+ The predefined token onto which all undefined values returned by
+ `yylex' are mapped. It cannot be used in the grammar, rather, use
+ `error'.
+
+ -- Directive: %union
+ Bison declaration to specify several possible data types for
+ semantic values. *Note The Collection of Value Types: Union Decl.
+
+ -- Macro: YYABORT
+ Macro to pretend that an unrecoverable syntax error has occurred,
+ by making `yyparse' return 1 immediately. The error reporting
+ function `yyerror' is not called. *Note The Parser Function
+ `yyparse': Parser Function.
+
+ For Java parsers, this functionality is invoked using `return
+ YYABORT;' instead.
+
+ -- Macro: YYACCEPT
+ Macro to pretend that a complete utterance of the language has been
+ read, by making `yyparse' return 0 immediately. *Note The Parser
+ Function `yyparse': Parser Function.
+
+ For Java parsers, this functionality is invoked using `return

+
+ -- Macro: YYBACKUP
+ Macro to discard a value from the parser stack and fake a lookahead
+ token. *Note Special Features for Use in Actions: Action Features.
+
+ -- Variable: yychar
+ External integer variable that contains the integer value of the
+ lookahead token. (In a pure parser, it is a local variable within
+ `yyparse'.) Error-recovery rule actions may examine this variable.
+ *Note Special Features for Use in Actions: Action Features.
+
+ -- Variable: yyclearin
+ Macro used in error-recovery rule actions. It clears the previous

+
+ -- Macro: YYDEBUG
+ Macro to define to equip the parser with tracing code. *Note

+ given a nonzero value, the parser will output information on input
+ symbols and parser action. *Note Tracing Your Parser: Tracing.
+
+ -- Macro: yyerrok
+ Macro to cause parser to recover immediately to its normal mode
+ after a syntax error. *Note Error Recovery::.
+
+ -- Macro: YYERROR
+ Cause an immediate syntax error. This statement initiates error
+ recovery just as if the parser itself had detected an error;
+ however, it does not call `yyerror', and does not print any
+ message. If you want to print an error message, call `yyerror'
+ explicitly before the `YYERROR;' statement. *Note Error
+ Recovery::.
+
+ For Java parsers, this functionality is invoked using `return
+ YYERROR;' instead.
+
+ -- Function: yyerror
+ User-supplied function to be called by `yyparse' on error. *Note
+ The Error Reporting Function `yyerror': Error Reporting.
+
+ -- Macro: YYERROR_VERBOSE
+ An obsolete macro that you define with `#define' in the prologue
+ to request verbose, specific error message strings when `yyerror'
+ is called. It doesn't matter what definition you use for
+ `YYERROR_VERBOSE', just whether you define it. Supported by the C
+ skeletons only; using `%error-verbose' is preferred. *Note Error
+ Reporting::.
+
+ -- Macro: YYFPRINTF
+ Macro used to output run-time traces. *Note Enabling Traces::.
+
+ -- Macro: YYINITDEPTH
+ Macro for specifying the initial size of the parser stack. *Note

+ extra arguments) for `yyparse' to pass to `yylex'. The use of this
+ macro is deprecated, and is supported only for Yacc like parsers.
+ *Note Calling Conventions for Pure Parsers: Pure Calling.
+
+ -- Variable: yylloc
+ External variable in which `yylex' should place the line and column
+ numbers associated with a token. (In a pure parser, it is a local
+ variable within `yyparse', and its address is passed to `yylex'.)
+ You can ignore this variable if you don't use the `@' feature in
+ the grammar actions. *Note Textual Locations of Tokens: Token
+ Locations. In semantic actions, it stores the location of the
+ lookahead token. *Note Actions and Locations: Actions and
+ Locations.
+
+ -- Type: YYLTYPE
+ Data type of `yylloc'; by default, a structure with four members.
+ *Note Data Types of Locations: Location Type.
+
+ -- Variable: yylval
+ External variable in which `yylex' should place the semantic value
+ associated with a token. (In a pure parser, it is a local
+ variable within `yyparse', and its address is passed to `yylex'.)
+ *Note Semantic Values of Tokens: Token Values. In semantic
+ actions, it stores the semantic value of the lookahead token.
+ *Note Actions: Actions.
+
+ -- Macro: YYMAXDEPTH
+ Macro for specifying the maximum size of the parser stack. *Note
+ Memory Management::.
+
+ -- Variable: yynerrs
+ Global variable which Bison increments each time it reports a
+ syntax error. (In a pure parser, it is a local variable within
+ `yyparse'. In a pure push parser, it is a member of yypstate.)
+ *Note The Error Reporting Function `yyerror': Error Reporting.
+
+ -- Function: yyparse
+ The parser function produced by Bison; call this function to start
+ parsing. *Note The Parser Function `yyparse': Parser Function.
+
+ -- Macro: YYPRINT
+ Macro used to output token semantic values. For `yacc.c' only.
+ Obsoleted by `%printer'. *Note The `YYPRINT' Macro: The YYPRINT
+ Macro.
+
+ -- Function: yypstate_delete
+ The function to delete a parser instance, produced by Bison in
+ push mode; call this function to delete the memory associated with
+ a parser. *Note The Parser Delete Function `yypstate_delete':
+ Parser Delete Function. (The current push parsing interface is
+ experimental and may evolve. More user feedback will help to
+ stabilize it.)
+
+ -- Function: yypstate_new
+ The function to create a parser instance, produced by Bison in
+ push mode; call this function to create a new parser. *Note The
+ Parser Create Function `yypstate_new': Parser Create Function.
+ (The current push parsing interface is experimental and may evolve.
+ More user feedback will help to stabilize it.)
+
+ -- Function: yypull_parse
+ The parser function produced by Bison in push mode; call this
+ function to parse the rest of the input stream. *Note The Pull
+ Parser Function `yypull_parse': Pull Parser Function. (The
+ current push parsing interface is experimental and may evolve.
+ More user feedback will help to stabilize it.)
+
+ -- Function: yypush_parse
+ The parser function produced by Bison in push mode; call this

+ `yypush_parse': Push Parser Function. (The current push parsing
+ interface is experimental and may evolve. More user feedback will
+ help to stabilize it.)
+
+ -- Macro: YYPARSE_PARAM
+ An obsolete macro for specifying the name of a parameter that
+ `yyparse' should accept. The use of this macro is deprecated, and
+ is supported only for Yacc like parsers. *Note Calling
+ Conventions for Pure Parsers: Pure Calling.
+
+ -- Macro: YYRECOVERING
+ The expression `YYRECOVERING ()' yields 1 when the parser is
+ recovering from a syntax error, and 0 otherwise. *Note Special
+ Features for Use in Actions: Action Features.
+
+ -- Macro: YYSTACK_USE_ALLOCA
+ Macro used to control the use of `alloca' when the deterministic
+ parser in C needs to extend its stacks. If defined to 0, the
+ parser will use `malloc' to extend its stacks. If defined to 1,
+ the parser will use `alloca'. Values other than 0 and 1 are
+ reserved for future Bison extensions. If not defined,
+ `YYSTACK_USE_ALLOCA' defaults to 0.
+
+ In the all-too-common case where your code may run on a host with a
+ limited stack and with unreliable stack-overflow checking, you
+ should set `YYMAXDEPTH' to a value that cannot possibly result in
+ unchecked stack overflow on any of your target hosts when `alloca'
+ is called. You can inspect the code that Bison generates in order
+ to determine the proper numeric values. This will require some
+ expertise in low-level implementation details.
+
+ -- Type: YYSTYPE
+ Data type of semantic values; `int' by default. *Note Data Types
+ of Semantic Values: Value Type.

+Appendix B Glossary
+*******************
+
+Accepting state
+ A state whose only action is the accept action. The accepting
+ state is thus a consistent state. *Note Understanding::.
+
+Backus-Naur Form (BNF; also called "Backus Normal Form")
+ Formal method of specifying context-free grammars originally
+ proposed by John Backus, and slightly improved by Peter Naur in
+ his 1960-01-02 committee document contributing to what became the
+ Algol 60 report. *Note Languages and Context-Free Grammars:
+ Language and Grammar.
+
+Consistent state
+ A state containing only one possible action. *Note Default
+ Reductions::.
+
+Context-free grammars
+ Grammars specified as rules that can be applied regardless of
+ context. Thus, if there is a rule which says that an integer can
+ be used as an expression, integers are allowed _anywhere_ an
+ expression is permitted. *Note Languages and Context-Free
+ Grammars: Language and Grammar.
+
+Default reduction
+ The reduction that a parser should perform if the current parser
+ state contains no other action for the lookahead token. In
+ permitted parser states, Bison declares the reduction with the
+ largest lookahead set to be the default reduction and removes that
+ lookahead set. *Note Default Reductions::.
+
+Defaulted state
+ A consistent state with a default reduction. *Note Default
+ Reductions::.
+
+Dynamic allocation
+ Allocation of memory that occurs during execution, rather than at
+ compile time or on entry to a function.
+
+Empty string
+ Analogous to the empty set in set theory, the empty string is a
+ character string of length zero.
+
+Finite-state stack machine
+ A "machine" that has discrete states in which it is said to exist
+ at each instant in time. As input to the machine is processed, the
+ machine moves from state to state as specified by the logic of the
+ machine. In the case of the parser, the input is the language
+ being parsed, and the states correspond to various stages in the
+ grammar rules. *Note The Bison Parser Algorithm: Algorithm.
+
+Generalized LR (GLR)
+ A parsing algorithm that can handle all context-free grammars,
+ including those that are not LR(1). It resolves situations that
+ Bison's deterministic parsing algorithm cannot by effectively
+ splitting off multiple parsers, trying all possible parsers, and
+ discarding those that fail in the light of additional right
+ context. *Note Generalized LR Parsing: Generalized LR Parsing.
+
+Grouping
+ A language construct that is (in general) grammatically divisible;
+ for example, `expression' or `declaration' in C. *Note Languages
+ and Context-Free Grammars: Language and Grammar.
+
+IELR(1) (Inadequacy Elimination LR(1))
+ A minimal LR(1) parser table construction algorithm. That is,
+ given any context-free grammar, IELR(1) generates parser tables
+ with the full language-recognition power of canonical LR(1) but
+ with nearly the same number of parser states as LALR(1). This
+ reduction in parser states is often an order of magnitude. More
+ importantly, because canonical LR(1)'s extra parser states may
+ contain duplicate conflicts in the case of non-LR(1) grammars, the
+ number of conflicts for IELR(1) is often an order of magnitude
+ less as well. This can significantly reduce the complexity of
+ developing a grammar. *Note LR Table Construction::.
+
+Infix operator
+ An arithmetic operator that is placed between the operands on
+ which it performs some operation.
+
+Input stream
+ A continuous flow of data between devices or programs.
+
+LAC (Lookahead Correction)
+ A parsing mechanism that fixes the problem of delayed syntax error
+ detection, which is caused by LR state merging, default
+ reductions, and the use of `%nonassoc'. Delayed syntax error
+ detection results in unexpected semantic actions, initiation of
+ error recovery in the wrong syntactic context, and an incorrect
+ list of expected tokens in a verbose syntax error message. *Note
+ LAC::.
+
+Language construct
+ One of the typical usage schemas of the language. For example,
+ one of the constructs of the C language is the `if' statement.
+ *Note Languages and Context-Free Grammars: Language and Grammar.
+
+Left associativity
+ Operators having left associativity are analyzed from left to
+ right: `a+b+c' first computes `a+b' and then combines with `c'.
+ *Note Operator Precedence: Precedence.
+
+Left recursion
+ A rule whose result symbol is also its first component symbol; for
+ example, `expseq1 : expseq1 ',' exp;'. *Note Recursive Rules:
+ Recursion.
+
+Left-to-right parsing
+ Parsing a sentence of a language by analyzing it token by token
+ from left to right. *Note The Bison Parser Algorithm: Algorithm.
+
+Lexical analyzer (scanner)
+ A function that reads an input stream and returns tokens one by
+ one. *Note The Lexical Analyzer Function `yylex': Lexical.
+
+Lexical tie-in
+ A flag, set by actions in the grammar rules, which alters the way
+ tokens are parsed. *Note Lexical Tie-ins::.
+
+Literal string token
+ A token which consists of two or more fixed characters. *Note
+ Symbols::.
+
+Lookahead token
+ A token already read but not yet shifted. *Note Lookahead Tokens:
+ Lookahead.
+
+LALR(1)
+ The class of context-free grammars that Bison (like most other
+ parser generators) can handle by default; a subset of LR(1).
+ *Note Mysterious Conflicts::.
+
+LR(1)
+ The class of context-free grammars in which at most one token of
+ lookahead is needed to disambiguate the parsing of any piece of
+ input.
+
+Nonterminal symbol
+ A grammar symbol standing for a grammatical construct that can be
+ expressed through rules in terms of smaller constructs; in other
+ words, a construct that is not a token. *Note Symbols::.
+
+Parser
+ A function that recognizes valid sentences of a language by
+ analyzing the syntax structure of a set of tokens passed to it
+ from a lexical analyzer.
+
+Postfix operator
+ An arithmetic operator that is placed after the operands upon
+ which it performs some operation.
+
+Reduction
+ Replacing a string of nonterminals and/or terminals with a single
+ nonterminal, according to a grammar rule. *Note The Bison Parser
+ Algorithm: Algorithm.
+
+Reentrant
+ A reentrant subprogram is a subprogram which can be in invoked any
+ number of times in parallel, without interference between the
+ various invocations. *Note A Pure (Reentrant) Parser: Pure Decl.
+
+Reverse polish notation
+ A language in which all operators are postfix operators.
+
+Right recursion
+ A rule whose result symbol is also its last component symbol; for
+ example, `expseq1: exp ',' expseq1;'. *Note Recursive Rules:
+ Recursion.
+
+Semantics
+ In computer languages, the semantics are specified by the actions
+ taken for each instance of the language, i.e., the meaning of each
+ statement. *Note Defining Language Semantics: Semantics.
+
+Shift
+ A parser is said to shift when it makes the choice of analyzing
+ further input from the stream rather than reducing immediately some
+ already-recognized rule. *Note The Bison Parser Algorithm:
+ Algorithm.
+
+Single-character literal
+ A single character that is recognized and interpreted as is.
+ *Note From Formal Rules to Bison Input: Grammar in Bison.
+
+Start symbol
+ The nonterminal symbol that stands for a complete valid utterance
+ in the language being parsed. The start symbol is usually listed
+ as the first nonterminal symbol in a language specification.
+ *Note The Start-Symbol: Start Decl.
+
+Symbol table
+ A data structure where symbol names and associated data are stored
+ during parsing to allow for recognition and use of existing
+ information in repeated uses of a symbol. *Note Multi-function
+ Calc::.
+
+Syntax error
+ An error encountered during parsing of an input stream due to
+ invalid syntax. *Note Error Recovery::.
+
+Token
+ A basic, grammatically indivisible unit of a language. The symbol
+ that describes a token in the grammar is a terminal symbol. The
+ input of the Bison parser is a stream of tokens which comes from
+ the lexical analyzer. *Note Symbols::.
+
+Terminal symbol
+ A grammar symbol that has no rules in the grammar and therefore is
+ grammatically indivisible. The piece of text it represents is a
+ token. *Note Languages and Context-Free Grammars: Language and
+ Grammar.
+
+Unreachable state
+ A parser state to which there does not exist a sequence of
+ transitions from the parser's start state. A state can become
+ unreachable during conflict resolution. *Note Unreachable
+ States::.

+ that the software does. But this License is not limited to
+ software manuals; it can be used for any textual work, regardless
+ of subject matter or whether it is published as a printed book.
+ We recommend this License principally for works whose purpose is
+ instruction or reference.
+
+ 1. APPLICABILITY AND DEFINITIONS
+
+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it
+ can be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You
+ accept the license if you copy, modify or distribute the work in a
+ way requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in
+ the notice that says that the Document is released under this
+ License. If a section does not fit the above definition of
+ Secondary then it is not allowed to be designated as Invariant.
+ The Document may contain zero Invariant Sections. If the Document
+ does not identify any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images
+ composed of pixels) generic paint programs or (for drawings) some
+ widely available drawing editor, and that is suitable for input to
+ text formatters or for automatic translation to a variety of
+ formats suitable for input to text formatters. A copy made in an
+ otherwise Transparent file format whose markup, or absence of
+ markup, has been arranged to thwart or discourage subsequent
+ modification by readers is not Transparent. An image format is
+ not Transparent if used for any substantial amount of text. A
+ copy that is not "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and
+ standard-conforming simple HTML, PostScript or PDF designed for
+ human modification. Examples of transparent image formats include
+ PNG, XCF and JPG. Opaque formats include proprietary formats that
+ can be read and edited only by proprietary word processors, SGML or
+ XML for which the DTD and/or processing tools are not generally
+ available, and the machine-generated HTML, PostScript or PDF
+ produced by some word processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow
+ the conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the
+ title equally prominent and visible. You may add other material
+ on the covers in addition. Copying with changes limited to the
+ covers, as long as they preserve the title of the Document and
+ satisfy these conditions, can be treated as verbatim copying in
+ other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a
+ machine-readable Transparent copy along with each Opaque copy, or
+ state in or with each Opaque copy a computer-network location from
+ which the general network-using public has access to download
+ using public-standard network protocols a complete Transparent
+ copy of the Document, free of added material. If you use the
+ latter option, you must take reasonably prudent steps, when you
+ begin distribution of Opaque copies in quantity, to ensure that
+ this Transparent copy will remain thus accessible at the stated
+ location until at least one year after the last time you
+ distribute an Opaque copy (directly or through your agents or
+ retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of
+ copies, to give them a chance to provide you with an updated
+ version of the Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with
+ the Modified Version filling the role of the Document, thus
+ licensing distribution and modification of the Modified Version to
+ whoever possesses a copy of it. In addition, you must do these
+ things in the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of
+ previous versions (which should, if there were any, be listed
+ in the History section of the Document). You may use the
+ same title as a previous version if the original publisher of
+ that version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on
+ the Title Page. If there is no section Entitled "History" in
+ the Document, create one stating the title, year, authors,
+ and publisher of the Document as given on its Title Page,
+ then add an item describing the Modified Version as stated in
+ the previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in
+ the "History" section. You may omit a network location for a
+ work that was published at least four years before the
+ Document itself, or if the original publisher of the version
+ it refers to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the
+ section all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section
+ titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option
+ designate some or all of these sections as invariant. To do this,
+ add their titles to the list of Invariant Sections in the Modified
+ Version's license notice. These titles must be distinct from any
+ other section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end
+ of the list of Cover Texts in the Modified Version. Only one
+ passage of Front-Cover Text and one of Back-Cover Text may be
+ added by (or through arrangements made by) any one entity. If the
+ Document already includes a cover text for the same cover,
+ previously added by you or by arrangement made by the same entity
+ you are acting on behalf of, you may not add another; but you may
+ replace the old one, on explicit permission from the previous
+ publisher that added the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination
+ all of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the
+ documents in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow
+ this License in all other respects regarding verbatim copying of
+ that document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of
+ a storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly
+ and finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from
+ you under this License. If your rights have been terminated and
+ not permanently reinstated, receipt of a copy of some or all of
+ the same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ `http://www.gnu.org/copyleft/'.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If
+ the Document does not specify a version number of this License,
+ you may choose any version ever published (not as a draft) by the
+ Free Software Foundation. If the Document specifies that a proxy
+ can decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+Introduction
+************
+
+"Bison" is a general-purpose parser generator that converts an
+annotated context-free grammar into a deterministic LR or generalized
+LR (GLR) parser employing LALR(1) parser tables. As an experimental
+feature, Bison can also generate IELR(1) or canonical LR(1) parser
+tables. Once you are proficient with Bison, you can use it to develop
+a wide range of language parsers, from those used in simple desk
+calculators to complex programming languages.
+
+ Bison is upward compatible with Yacc: all properly-written Yacc
+grammars ought to work with Bison with no change. Anyone familiar with
+Yacc should be able to use Bison with little trouble. You need to be
+fluent in C or C++ programming in order to use Bison or to understand
+this manual. Java is also supported as an experimental feature.
+
+ We begin with tutorial chapters that explain the basic concepts of
+using Bison and show three explained examples, each building on the
+last. If you don't know Bison or Yacc, start by reading these
+chapters. Reference chapters follow, which describe specific aspects
+of Bison in detail.
+
+ Bison was written originally by Robert Corbett. Richard Stallman
+made it Yacc-compatible. Wilfred Hansen of Carnegie Mellon University
+added multi-character string literals and other features. Since then,
+Bison has grown more robust and evolved many other new features thanks
+to the hard work of a long list of volunteers. For details, see the
+`THANKS' and `ChangeLog' files included in the Bison distribution.
+
+ This edition corresponds to version 2.5.91 of Bison.

+Conditions for Using Bison
+**************************
+
+The distribution terms for Bison-generated parsers permit using the
+parsers in nonfree programs. Before Bison version 2.2, these extra
+permissions applied only when Bison was generating LALR(1) parsers in
+C. And before Bison version 1.24, Bison-generated parsers could be
+used only in programs that were free software.
+
+ The other GNU programming tools, such as the GNU C compiler, have
+never had such a requirement. They could always be used for nonfree
+software. The reason Bison was different was not due to a special
+policy decision; it resulted from applying the usual General Public
+License to all of the Bison source code.
+
+ The main output of the Bison utility--the Bison parser implementation
+file--contains a verbatim copy of a sizable piece of Bison, which is
+the code for the parser's implementation. (The actions from your
+grammar are inserted into this implementation at one point, but most of
+the rest of the implementation is not changed.) When we applied the
+GPL terms to the skeleton code for the parser's implementation, the
+effect was to restrict the use of Bison output to free software.
+
+ We didn't change the terms because of sympathy for people who want to
+make software proprietary. *Software should be free.* But we
+concluded that limiting Bison's use to free software was doing little to
+encourage people to make other software free. So we decided to make the
+practical conditions for using Bison match the practical conditions for
+using the other GNU tools.
+
+ This exception applies when Bison is generating code for a parser.
+You can tell whether the exception applies to a Bison output file by
+inspecting the file for text beginning with "As a special
+exception...". The text spells out the exact terms of the exception.

+GNU GENERAL PUBLIC LICENSE
+**************************
+
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. `http://fsf.org/'
+
+ Everyone is permitted to copy and distribute verbatim copies of this
+ license document, but changing it is not allowed.
+
+Preamble
+========
+
+The GNU General Public License is a free, copyleft license for software
+and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains
+free software for all its users. We, the Free Software Foundation, use
+the GNU General Public License for most of our software; it applies
+also to any other work released this way by its authors. You can apply
+it to your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you
+have certain responsibilities if you distribute copies of the software,
+or if you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the
+manufacturer can do so. This is fundamentally incompatible with the
+aim of protecting users' freedom to change the software. The
+systematic pattern of such abuse occurs in the area of products for
+individuals to use, which is precisely where it is most unacceptable.
+Therefore, we have designed this version of the GPL to prohibit the
+practice for those products. If such problems arise substantially in
+other domains, we stand ready to extend this provision to those domains
+in future versions of the GPL, as needed to protect the freedom of
+users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+TERMS AND CONDITIONS
+====================
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public
+ License.
+
+ "Copyright" also means copyright-like laws that apply to other
+ kinds of works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+ License. Each licensee is addressed as "you". "Licensees" and
+ "recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the
+ work in a fashion requiring copyright permission, other than the
+ making of an exact copy. The resulting work is called a "modified
+ version" of the earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work
+ based on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+ permission, would make you directly or secondarily liable for
+ infringement under applicable copyright law, except executing it
+ on a computer or modifying a private copy. Propagation includes
+ copying, distribution (with or without modification), making
+ available to the public, and in some countries other activities as
+ well.
+
+ To "convey" a work means any kind of propagation that enables other
+ parties to make or receive copies. Mere interaction with a user
+ through a computer network, with no transfer of a copy, is not
+ conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+ to the extent that it includes a convenient and prominently visible
+ feature that (1) displays an appropriate copyright notice, and (2)
+ tells the user that there is no warranty for the work (except to
+ the extent that warranties are provided), that licensees may
+ convey the work under this License, and how to view a copy of this
+ License. If the interface presents a list of user commands or
+ options, such as a menu, a prominent item in the list meets this
+ criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+ for making modifications to it. "Object code" means any
+ non-source form of a work.
+
+ A "Standard Interface" means an interface that either is an
+ official standard defined by a recognized standards body, or, in
+ the case of interfaces specified for a particular programming
+ language, one that is widely used among developers working in that
+ language.
+
+ The "System Libraries" of an executable work include anything,
+ other than the work as a whole, that (a) is included in the normal
+ form of packaging a Major Component, but which is not part of that
+ Major Component, and (b) serves only to enable use of the work
+ with that Major Component, or to implement a Standard Interface
+ for which an implementation is available to the public in source
+ code form. A "Major Component", in this context, means a major
+ essential component (kernel, window system, and so on) of the
+ specific operating system (if any) on which the executable work
+ runs, or a compiler used to produce the work, or an object code
+ interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+ the source code needed to generate, install, and (for an executable
+ work) run the object code and to modify the work, including
+ scripts to control those activities. However, it does not include
+ the work's System Libraries, or general-purpose tools or generally
+ available free programs which are used unmodified in performing
+ those activities but which are not part of the work. For example,
+ Corresponding Source includes interface definition files
+ associated with source files for the work, and the source code for
+ shared libraries and dynamically linked subprograms that the work
+ is specifically designed to require, such as by intimate data
+ communication or control flow between those subprograms and other
+ parts of the work.
+
+ The Corresponding Source need not include anything that users can
+ regenerate automatically from other parts of the Corresponding
+ Source.
+
+ The Corresponding Source for a work in source code form is that
+ same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+ copyright on the Program, and are irrevocable provided the stated
+ conditions are met. This License explicitly affirms your unlimited
+ permission to run the unmodified Program. The output from running
+ a covered work is covered by this License only if the output,
+ given its content, constitutes a covered work. This License
+ acknowledges your rights of fair use or other equivalent, as
+ provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+ convey, without conditions so long as your license otherwise
+ remains in force. You may convey covered works to others for the
+ sole purpose of having them make modifications exclusively for
+ you, or provide you with facilities for running those works,
+ provided that you comply with the terms of this License in
+ conveying all material for which you do not control copyright.
+ Those thus making or running the covered works for you must do so
+ exclusively on your behalf, under your direction and control, on
+ terms that prohibit them from making any copies of your
+ copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+ the conditions stated below. Sublicensing is not allowed; section
+ 10 makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+ measure under any applicable law fulfilling obligations under
+ article 11 of the WIPO copyright treaty adopted on 20 December
+ 1996, or similar laws prohibiting or restricting circumvention of
+ such measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+ circumvention of technological measures to the extent such
+ circumvention is effected by exercising rights under this License
+ with respect to the covered work, and you disclaim any intention
+ to limit operation or modification of the work as a means of
+ enforcing, against the work's users, your or third parties' legal
+ rights to forbid circumvention of technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+ receive it, in any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright notice;
+ keep intact all notices stating that this License and any
+ non-permissive terms added in accord with section 7 apply to the
+ code; keep intact all notices of the absence of any warranty; and
+ give all recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+ and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+ produce it from the Program, in the form of source code under the
+ terms of section 4, provided that you also meet all of these
+ conditions:
+
+ a. The work must carry prominent notices stating that you
+ modified it, and giving a relevant date.
+
+ b. The work must carry prominent notices stating that it is
+ released under this License and any conditions added under
+ section 7. This requirement modifies the requirement in
+ section 4 to "keep intact all notices".
+
+ c. You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable
+ section 7 additional terms, to the whole of the work, and all
+ its parts, regardless of how they are packaged. This License
+ gives no permission to license the work in any other way, but
+ it does not invalidate such permission if you have separately
+ received it.
+
+ d. If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has
+ interactive interfaces that do not display Appropriate Legal
+ Notices, your work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+ works, which are not by their nature extensions of the covered
+ work, and which are not combined with it such as to form a larger
+ program, in or on a volume of a storage or distribution medium, is
+ called an "aggregate" if the compilation and its resulting
+ copyright are not used to limit the access or legal rights of the
+ compilation's users beyond what the individual works permit.
+ Inclusion of a covered work in an aggregate does not cause this
+ License to apply to the other parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+ of sections 4 and 5, provided that you also convey the
+ machine-readable Corresponding Source under the terms of this
+ License, in one of these ways:
+
+ a. Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b. Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for
+ as long as you offer spare parts or customer support for that
+ product model, to give anyone who possesses the object code
+ either (1) a copy of the Corresponding Source for all the
+ software in the product that is covered by this License, on a
+ durable physical medium customarily used for software
+ interchange, for a price no more than your reasonable cost of
+ physically performing this conveying of source, or (2) access
+ to copy the Corresponding Source from a network server at no
+ charge.
+
+ c. Convey individual copies of the object code with a copy of
+ the written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially,
+ and only if you received the object code with such an offer,
+ in accord with subsection 6b.
+
+ d. Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access
+ to the Corresponding Source in the same way through the same
+ place at no further charge. You need not require recipients
+ to copy the Corresponding Source along with the object code.
+ If the place to copy the object code is a network server, the
+ Corresponding Source may be on a different server (operated
+ by you or a third party) that supports equivalent copying
+ facilities, provided you maintain clear directions next to
+ the object code saying where to find the Corresponding Source.
+ Regardless of what server hosts the Corresponding Source, you
+ remain obligated to ensure that it is available for as long
+ as needed to satisfy these requirements.
+
+ e. Convey the object code using peer-to-peer transmission,
+ provided you inform other peers where the object code and
+ Corresponding Source of the work are being offered to the
+ general public at no charge under subsection 6d.
+
+
+ A separable portion of the object code, whose source code is
+ excluded from the Corresponding Source as a System Library, need
+ not be included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means
+ any tangible personal property which is normally used for personal,
+ family, or household purposes, or (2) anything designed or sold for
+ incorporation into a dwelling. In determining whether a product
+ is a consumer product, doubtful cases shall be resolved in favor of
+ coverage. For a particular product received by a particular user,
+ "normally used" refers to a typical or common use of that class of
+ product, regardless of the status of the particular user or of the
+ way in which the particular user actually uses, or expects or is
+ expected to use, the product. A product is a consumer product
+ regardless of whether the product has substantial commercial,
+ industrial or non-consumer uses, unless such uses represent the
+ only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+ procedures, authorization keys, or other information required to
+ install and execute modified versions of a covered work in that
+ User Product from a modified version of its Corresponding Source.
+ The information must suffice to ensure that the continued
+ functioning of the modified object code is in no case prevented or
+ interfered with solely because modification has been made.
+
+ If you convey an object code work under this section in, or with,
+ or specifically for use in, a User Product, and the conveying
+ occurs as part of a transaction in which the right of possession
+ and use of the User Product is transferred to the recipient in
+ perpetuity or for a fixed term (regardless of how the transaction
+ is characterized), the Corresponding Source conveyed under this
+ section must be accompanied by the Installation Information. But
+ this requirement does not apply if neither you nor any third party
+ retains the ability to install modified object code on the User
+ Product (for example, the work has been installed in ROM).
+
+ The requirement to provide Installation Information does not
+ include a requirement to continue to provide support service,
+ warranty, or updates for a work that has been modified or
+ installed by the recipient, or for the User Product in which it
+ has been modified or installed. Access to a network may be denied
+ when the modification itself materially and adversely affects the
+ operation of the network or violates the rules and protocols for
+ communication across the network.
+
+ Corresponding Source conveyed, and Installation Information
+ provided, in accord with this section must be in a format that is
+ publicly documented (and with an implementation available to the
+ public in source code form), and must require no special password
+ or key for unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of
+ this License by making exceptions from one or more of its
+ conditions. Additional permissions that are applicable to the
+ entire Program shall be treated as though they were included in
+ this License, to the extent that they are valid under applicable
+ law. If additional permissions apply only to part of the Program,
+ that part may be used separately under those permissions, but the
+ entire Program remains governed by this License without regard to
+ the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+ remove any additional permissions from that copy, or from any part
+ of it. (Additional permissions may be written to require their own
+ removal in certain cases when you modify the work.) You may place
+ additional permissions on material, added by you to a covered work,
+ for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material
+ you add to a covered work, you may (if authorized by the copyright
+ holders of that material) supplement the terms of this License
+ with terms:
+
+ a. Disclaiming warranty or limiting liability differently from
+ the terms of sections 15 and 16 of this License; or
+
+ b. Requiring preservation of specified reasonable legal notices
+ or author attributions in that material or in the Appropriate
+ Legal Notices displayed by works containing it; or
+
+ c. Prohibiting misrepresentation of the origin of that material,
+ or requiring that modified versions of such material be
+ marked in reasonable ways as different from the original
+ version; or
+
+ d. Limiting the use for publicity purposes of names of licensors
+ or authors of the material; or
+
+ e. Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f. Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified
+ versions of it) with contractual assumptions of liability to
+ the recipient, for any liability that these contractual
+ assumptions directly impose on those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+ restrictions" within the meaning of section 10. If the Program as
+ you received it, or any part of it, contains a notice stating that
+ it is governed by this License along with a term that is a further
+ restriction, you may remove that term. If a license document
+ contains a further restriction but permits relicensing or
+ conveying under this License, you may add to a covered work
+ material governed by the terms of that license document, provided
+ that the further restriction does not survive such relicensing or
+ conveying.
+
+ If you add terms to a covered work in accord with this section, you
+ must place, in the relevant source files, a statement of the
+ additional terms that apply to those files, or a notice indicating
+ where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in
+ the form of a separately written license, or stated as exceptions;
+ the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+ provided under this License. Any attempt otherwise to propagate or
+ modify it is void, and will automatically terminate your rights
+ under this License (including any patent licenses granted under
+ the third paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly
+ and finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from
+ you under this License. If your rights have been terminated and
+ not permanently reinstated, you do not qualify to receive new
+ licenses for the same material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+ run a copy of the Program. Ancillary propagation of a covered work
+ occurring solely as a consequence of using peer-to-peer
+ transmission to receive a copy likewise does not require
+ acceptance. However, nothing other than this License grants you
+ permission to propagate or modify any covered work. These actions
+ infringe copyright if you do not accept this License. Therefore,
+ by modifying or propagating a covered work, you indicate your
+ acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+ receives a license from the original licensors, to run, modify and
+ propagate that work, subject to this License. You are not
+ responsible for enforcing compliance by third parties with this
+ License.
+
+ An "entity transaction" is a transaction transferring control of an
+ organization, or substantially all assets of one, or subdividing an
+ organization, or merging organizations. If propagation of a
+ covered work results from an entity transaction, each party to that
+ transaction who receives a copy of the work also receives whatever
+ licenses to the work the party's predecessor in interest had or
+ could give under the previous paragraph, plus a right to
+ possession of the Corresponding Source of the work from the
+ predecessor in interest, if the predecessor has it or can get it
+ with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+ rights granted or affirmed under this License. For example, you
+ may not impose a license fee, royalty, or other charge for
+ exercise of rights granted under this License, and you may not
+ initiate litigation (including a cross-claim or counterclaim in a
+ lawsuit) alleging that any patent claim is infringed by making,
+ using, selling, offering for sale, or importing the Program or any
+ portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+ License of the Program or a work on which the Program is based.
+ The work thus licensed is called the contributor's "contributor
+ version".
+
+ A contributor's "essential patent claims" are all patent claims
+ owned or controlled by the contributor, whether already acquired or
+ hereafter acquired, that would be infringed by some manner,
+ permitted by this License, of making, using, or selling its
+ contributor version, but do not include claims that would be
+ infringed only as a consequence of further modification of the
+ contributor version. For purposes of this definition, "control"
+ includes the right to grant patent sublicenses in a manner
+ consistent with the requirements of this License.
+
+ Each contributor grants you a non-exclusive, worldwide,
+ royalty-free patent license under the contributor's essential
+ patent claims, to make, use, sell, offer for sale, import and
+ otherwise run, modify and propagate the contents of its
+ contributor version.
+
+ In the following three paragraphs, a "patent license" is any
+ express agreement or commitment, however denominated, not to
+ enforce a patent (such as an express permission to practice a
+ patent or covenant not to sue for patent infringement). To
+ "grant" such a patent license to a party means to make such an
+ agreement or commitment not to enforce a patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent
+ license, and the Corresponding Source of the work is not available
+ for anyone to copy, free of charge and under the terms of this
+ License, through a publicly available network server or other
+ readily accessible means, then you must either (1) cause the
+ Corresponding Source to be so available, or (2) arrange to deprive
+ yourself of the benefit of the patent license for this particular
+ work, or (3) arrange, in a manner consistent with the requirements
+ of this License, to extend the patent license to downstream
+ recipients. "Knowingly relying" means you have actual knowledge
+ that, but for the patent license, your conveying the covered work
+ in a country, or your recipient's use of the covered work in a
+ country, would infringe one or more identifiable patents in that
+ country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+ arrangement, you convey, or propagate by procuring conveyance of, a
+ covered work, and grant a patent license to some of the parties
+ receiving the covered work authorizing them to use, propagate,
+ modify or convey a specific copy of the covered work, then the
+ patent license you grant is automatically extended to all
+ recipients of the covered work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+ the scope of its coverage, prohibits the exercise of, or is
+ conditioned on the non-exercise of one or more of the rights that
+ are specifically granted under this License. You may not convey a
+ covered work if you are a party to an arrangement with a third
+ party that is in the business of distributing software, under
+ which you make payment to the third party based on the extent of
+ your activity of conveying the work, and under which the third
+ party grants, to any of the parties who would receive the covered
+ work from you, a discriminatory patent license (a) in connection
+ with copies of the covered work conveyed by you (or copies made
+ from those copies), or (b) primarily for and in connection with
+ specific products or compilations that contain the covered work,
+ unless you entered into that arrangement, or that patent license
+ was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+ any implied license or other defenses to infringement that may
+ otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order,
+ agreement or otherwise) that contradict the conditions of this
+ License, they do not excuse you from the conditions of this
+ License. If you cannot convey a covered work so as to satisfy
+ simultaneously your obligations under this License and any other
+ pertinent obligations, then as a consequence you may not convey it
+ at all. For example, if you agree to terms that obligate you to
+ collect a royalty for further conveying from those to whom you
+ convey the Program, the only way you could satisfy both those
+ terms and this License would be to refrain entirely from conveying
+ the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+ permission to link or combine any covered work with a work licensed
+ under version 3 of the GNU Affero General Public License into a
+ single combined work, and to convey the resulting work. The terms
+ of this License will continue to apply to the part which is the
+ covered work, but the special requirements of the GNU Affero
+ General Public License, section 13, concerning interaction through

+
+1.1 Languages and Context-Free Grammars
+=======================================
+
+In order for Bison to parse a language, it must be described by a
+"context-free grammar". This means that you specify one or more
+"syntactic groupings" and give rules for constructing them from their
+parts. For example, in the C language, one kind of grouping is called
+an `expression'. One rule for making an expression might be, "An
+expression can be made of a minus sign and another expression".
+Another would be, "An expression can be an integer". As you can see,
+rules are often recursive, but there must be at least one rule which
+leads out of the recursion.
+
+ The most common formal system for presenting such rules for humans
+to read is "Backus-Naur Form" or "BNF", which was developed in order to
+specify the language Algol 60. Any grammar expressed in BNF is a
+context-free grammar. The input to Bison is essentially
+machine-readable BNF.
+
+ There are various important subclasses of context-free grammars.
+Although it can handle almost all context-free grammars, Bison is
+optimized for what are called LR(1) grammars. In brief, in these
+grammars, it must be possible to tell how to parse any portion of an
+input string with just a single token of lookahead. For historical
+reasons, Bison by default is limited by the additional restrictions of
+LALR(1), which is hard to explain simply. *Note Mysterious
+Conflicts::, for more information on this. As an experimental feature,
+you can escape these additional restrictions by requesting IELR(1) or
+canonical LR(1) parser tables. *Note LR Table Construction::, to learn
+how.
+
+ Parsers for LR(1) grammars are "deterministic", meaning roughly that
+the next grammar rule to apply at any point in the input is uniquely
+determined by the preceding input and a fixed, finite portion (called a
+"lookahead") of the remaining input. A context-free grammar can be
+"ambiguous", meaning that there are multiple ways to apply the grammar
+rules to get the same inputs. Even unambiguous grammars can be
+"nondeterministic", meaning that no fixed lookahead always suffices to
+determine the next grammar rule to apply. With the proper
+declarations, Bison is also able to parse these more general
+context-free grammars, using a technique known as GLR parsing (for
+Generalized LR). Bison's GLR parsers are able to handle any
+context-free grammar for which the number of possible parses of any
+given string is finite.
+
+ In the formal grammatical rules for a language, each kind of
+syntactic unit or grouping is named by a "symbol". Those which are
+built by grouping smaller constructs according to grammatical rules are
+called "nonterminal symbols"; those which can't be subdivided are called
+"terminal symbols" or "token types". We call a piece of input
+corresponding to a single terminal symbol a "token", and a piece
+corresponding to a single nonterminal symbol a "grouping".
+
+ We can use the C language as an example of what symbols, terminal and
+nonterminal, mean. The tokens of C are identifiers, constants (numeric
+and string), and the various keywords, arithmetic operators and
+punctuation marks. So the terminal symbols of a grammar for C include
+`identifier', `number', `string', plus one symbol for each keyword,
+operator or punctuation mark: `if', `return', `const', `static', `int',
+`char', `plus-sign', `open-brace', `close-brace', `comma' and many more.
+(These tokens can be subdivided into characters, but that is a matter of
+lexicography, not grammar.)
+
+ Here is a simple C function subdivided into tokens:
+
+ int /* keyword `int' */
+ square (int x) /* identifier, open-paren, keyword `int',
+ identifier, close-paren */
+ { /* open-brace */
+ return x * x; /* keyword `return', identifier, asterisk,
+ identifier, semicolon */
+ } /* close-brace */
+
+ The syntactic groupings of C include the expression, the statement,
+the declaration, and the function definition. These are represented in
+the grammar of C by nonterminal symbols `expression', `statement',
+`declaration' and `function definition'. The full grammar uses dozens
+of additional language constructs, each with its own nonterminal
+symbol, in order to express the meanings of these four. The example
+above is a function definition; it contains one declaration, and one
+statement. In the statement, each `x' is an expression and so is `x *
+x'.
+
+ Each nonterminal symbol must have grammatical rules showing how it
+is made out of simpler constructs. For example, one kind of C
+statement is the `return' statement; this would be described with a
+grammar rule which reads informally as follows:
+
+ A `statement' can be made of a `return' keyword, an `expression'
+ and a `semicolon'.
+
+There would be many other rules for `statement', one for each kind of
+statement in C.
+
+ One nonterminal symbol must be distinguished as the special one which
+defines a complete utterance in the language. It is called the "start
+symbol". In a compiler, this means a complete input program. In the C
+language, the nonterminal symbol `sequence of definitions and
+declarations' plays this role.
+
+ For example, `1 + 2' is a valid C expression--a valid part of a C
+program--but it is not valid as an _entire_ C program. In the
+context-free grammar of C, this follows from the fact that `expression'
+is not the start symbol.
+
+ The Bison parser reads a sequence of tokens as its input, and groups
+the tokens using the grammar rules. If the input is valid, the end
+result is that the entire token sequence reduces to a single grouping
+whose symbol is the grammar's start symbol. If we use a grammar for C,
+the entire input must be a `sequence of definitions and declarations'.
+If not, the parser reports a syntax error.

+
+1.2 From Formal Rules to Bison Input
+====================================
+
+A formal grammar is a mathematical construct. To define the language
+for Bison, you must write a file expressing the grammar in Bison syntax:
+a "Bison grammar" file. *Note Bison Grammar Files: Grammar File.
+
+ A nonterminal symbol in the formal grammar is represented in Bison
+input as an identifier, like an identifier in C. By convention, it
+should be in lower case, such as `expr', `stmt' or `declaration'.
+
+ The Bison representation for a terminal symbol is also called a
+"token type". Token types as well can be represented as C-like
+identifiers. By convention, these identifiers should be upper case to
+distinguish them from nonterminals: for example, `INTEGER',
+`IDENTIFIER', `IF' or `RETURN'. A terminal symbol that stands for a
+particular keyword in the language should be named after that keyword
+converted to upper case. The terminal symbol `error' is reserved for
+error recovery. *Note Symbols::.
+
+ A terminal symbol can also be represented as a character literal,
+just like a C character constant. You should do this whenever a token
+is just a single character (parenthesis, plus-sign, etc.): use that
+same character in a literal as the terminal symbol for that token.
+
+ A third way to represent a terminal symbol is with a C string
+constant containing several characters. *Note Symbols::, for more
+information.
+
+ The grammar rules also have an expression in Bison syntax. For
+example, here is the Bison rule for a C `return' statement. The
+semicolon in quotes is a literal character token, representing part of
+the C syntax for the statement; the naked semicolon, and the colon, are
+Bison punctuation used in every rule.
+
+ stmt: RETURN expr ';' ;
+
+*Note Syntax of Grammar Rules: Rules.
+
+\1f
+File: bison.info, Node: Semantic Values, Next: Semantic Actions, Prev: Grammar in Bison, Up: Concepts
+
+1.3 Semantic Values
+===================
+
+A formal grammar selects tokens only by their classifications: for
+example, if a rule mentions the terminal symbol `integer constant', it
+means that _any_ integer constant is grammatically valid in that
+position. The precise value of the constant is irrelevant to how to
+parse the input: if `x+4' is grammatical then `x+1' or `x+3989' is
+equally grammatical.
+
+ But the precise value is very important for what the input means
+once it is parsed. A compiler is useless if it fails to distinguish
+between 4, 1 and 3989 as constants in the program! Therefore, each
+token in a Bison grammar has both a token type and a "semantic value".
+*Note Defining Language Semantics: Semantics, for details.
+
+ The token type is a terminal symbol defined in the grammar, such as
+`INTEGER', `IDENTIFIER' or `',''. It tells everything you need to know
+to decide where the token may validly appear and how to group it with
+other tokens. The grammar rules know nothing about tokens except their
+types.
+
+ The semantic value has all the rest of the information about the
+meaning of the token, such as the value of an integer, or the name of an
+identifier. (A token such as `','' which is just punctuation doesn't
+need to have any semantic value.)
+
+ For example, an input token might be classified as token type
+`INTEGER' and have the semantic value 4. Another input token might
+have the same token type `INTEGER' but value 3989. When a grammar rule
+says that `INTEGER' is allowed, either of these tokens is acceptable
+because each is an `INTEGER'. When the parser accepts the token, it
+keeps track of the token's semantic value.
+
+ Each grouping can also have a semantic value as well as its
+nonterminal symbol. For example, in a calculator, an expression
+typically has a semantic value that is a number. In a compiler for a
+programming language, an expression typically has a semantic value that
+is a tree structure describing the meaning of the expression.
+
+\1f
+File: bison.info, Node: Semantic Actions, Next: GLR Parsers, Prev: Semantic Values, Up: Concepts
+
+1.4 Semantic Actions
+====================
+
+In order to be useful, a program must do more than parse input; it must
+also produce some output based on the input. In a Bison grammar, a
+grammar rule can have an "action" made up of C statements. Each time
+the parser recognizes a match for that rule, the action is executed.
+*Note Actions::.
+
+ Most of the time, the purpose of an action is to compute the
+semantic value of the whole construct from the semantic values of its
+parts. For example, suppose we have a rule which says an expression
+can be the sum of two expressions. When the parser recognizes such a
+sum, each of the subexpressions has a semantic value which describes
+how it was built up. The action for this rule should create a similar
+sort of value for the newly recognized larger expression.
+
+ For example, here is a rule that says an expression can be the sum of
+two subexpressions:
+
+ expr: expr '+' expr { $$ = $1 + $3; } ;
+
+The action says how to produce the semantic value of the sum expression
+from the values of the two subexpressions.
+

+
+1.5 Writing GLR Parsers
+=======================
+
+In some grammars, Bison's deterministic LR(1) parsing algorithm cannot
+decide whether to apply a certain grammar rule at a given point. That
+is, it may not be able to decide (on the basis of the input read so
+far) which of two possible reductions (applications of a grammar rule)
+applies, or whether to apply a reduction or read more of the input and
+apply a reduction later in the input. These are known respectively as
+"reduce/reduce" conflicts (*note Reduce/Reduce::), and "shift/reduce"
+conflicts (*note Shift/Reduce::).
+
+ To use a grammar that is not easily modified to be LR(1), a more
+general parsing algorithm is sometimes necessary. If you include
+`%glr-parser' among the Bison declarations in your file (*note Grammar
+Outline::), the result is a Generalized LR (GLR) parser. These parsers
+handle Bison grammars that contain no unresolved conflicts (i.e., after
+applying precedence declarations) identically to deterministic parsers.
+However, when faced with unresolved shift/reduce and reduce/reduce
+conflicts, GLR parsers use the simple expedient of doing both,
+effectively cloning the parser to follow both possibilities. Each of
+the resulting parsers can again split, so that at any given time, there
+can be any number of possible parses being explored. The parsers
+proceed in lockstep; that is, all of them consume (shift) a given input
+symbol before any of them proceed to the next. Each of the cloned
+parsers eventually meets one of two possible fates: either it runs into
+a parsing error, in which case it simply vanishes, or it merges with
+another parser, because the two of them have reduced the input to an
+identical set of symbols.
+
+ During the time that there are multiple parsers, semantic actions are
+recorded, but not performed. When a parser disappears, its recorded
+semantic actions disappear as well, and are never performed. When a
+reduction makes two parsers identical, causing them to merge, Bison
+records both sets of semantic actions. Whenever the last two parsers
+merge, reverting to the single-parser case, Bison resolves all the
+outstanding actions either by precedences given to the grammar rules
+involved, or by performing both actions, and then calling a designated
+user-defined function on the resulting values to produce an arbitrary
+merged result.

+
+1.5.1 Using GLR on Unambiguous Grammars
+---------------------------------------
+
+In the simplest cases, you can use the GLR algorithm to parse grammars
+that are unambiguous but fail to be LR(1). Such grammars typically
+require more than one symbol of lookahead.
+
+ Consider a problem that arises in the declaration of enumerated and
+subrange types in the programming language Pascal. Here are some
+examples:
+
+ type subrange = lo .. hi;
+ type enum = (a, b, c);
+
+The original language standard allows only numeric literals and
+constant identifiers for the subrange bounds (`lo' and `hi'), but
+Extended Pascal (ISO/IEC 10206) and many other Pascal implementations
+allow arbitrary expressions there. This gives rise to the following
+situation, containing a superfluous pair of parentheses:
+
+ type subrange = (a) .. b;
+
+Compare this to the following declaration of an enumerated type with
+only one value:
+
+ type enum = (a);
+
+(These declarations are contrived, but they are syntactically valid,
+and more-complicated cases can come up in practical programs.)
+
+ These two declarations look identical until the `..' token. With
+normal LR(1) one-token lookahead it is not possible to decide between
+the two forms when the identifier `a' is parsed. It is, however,
+desirable for a parser to decide this, since in the latter case `a'
+must become a new identifier to represent the enumeration value, while
+in the former case `a' must be evaluated with its current meaning,
+which may be a constant or even a function call.
+
+ You could parse `(a)' as an "unspecified identifier in parentheses",
+to be resolved later, but this typically requires substantial
+contortions in both semantic actions and large parts of the grammar,
+where the parentheses are nested in the recursive rules for expressions.
+
+ You might think of using the lexer to distinguish between the two
+forms by returning different tokens for currently defined and undefined
+identifiers. But if these declarations occur in a local scope, and `a'
+is defined in an outer scope, then both forms are possible--either
+locally redefining `a', or using the value of `a' from the outer scope.
+So this approach cannot work.
+
+ A simple solution to this problem is to declare the parser to use
+the GLR algorithm. When the GLR parser reaches the critical state, it
+merely splits into two branches and pursues both syntax rules
+simultaneously. Sooner or later, one of them runs into a parsing
+error. If there is a `..' token before the next `;', the rule for
+enumerated types fails since it cannot accept `..' anywhere; otherwise,
+the subrange type rule fails since it requires a `..' token. So one of
+the branches fails silently, and the other one continues normally,
+performing all the intermediate actions that were postponed during the
+split.
+
+ If the input is syntactically incorrect, both branches fail and the
+parser reports a syntax error as usual.
+
+ The effect of all this is that the parser seems to "guess" the
+correct branch to take, or in other words, it seems to use more
+lookahead than the underlying LR(1) algorithm actually allows for. In
+this example, LR(2) would suffice, but also some cases that are not
+LR(k) for any k can be handled this way.
+
+ In general, a GLR parser can take quadratic or cubic worst-case time,
+and the current Bison parser even takes exponential time and space for
+some grammars. In practice, this rarely happens, and for many grammars
+it is possible to prove that it cannot happen. The present example
+contains only one conflict between two rules, and the type-declaration
+context containing the conflict cannot be nested. So the number of
+branches that can exist at any time is limited by the constant 2, and
+the parsing time is still linear.
+
+ Here is a Bison grammar corresponding to the example above. It
+parses a vastly simplified form of Pascal type declarations.
+
+ %token TYPE DOTDOT ID
+
+ %left '+' '-'
+ %left '*' '/'
+
+ %%
+
+ type_decl: TYPE ID '=' type ';' ;
+
+ type:
+ '(' id_list ')'
+ | expr DOTDOT expr
+ ;
+
+ id_list:
+ ID
+ | id_list ',' ID
+ ;
+
+ expr:
+ '(' expr ')'
+ | expr '+' expr
+ | expr '-' expr
+ | expr '*' expr
+ | expr '/' expr
+ | ID
+ ;
+
+ When used as a normal LR(1) grammar, Bison correctly complains about
+one reduce/reduce conflict. In the conflicting situation the parser
+chooses one of the alternatives, arbitrarily the one declared first.
+Therefore the following correct input is not recognized:
+
+ type t = (a) .. b;
+
+ The parser can be turned into a GLR parser, while also telling Bison
+to be silent about the one known reduce/reduce conflict, by adding
+these two declarations to the Bison grammar file (before the first
+`%%'):
+
+ %glr-parser
+ %expect-rr 1
+
+No change in the grammar itself is required. Now the parser recognizes
+all valid declarations, according to the limited syntax above,
+transparently. In fact, the user does not even notice when the parser
+splits.
+
+ So here we have a case where we can use the benefits of GLR, almost
+without disadvantages. Even in simple cases like this, however, there
+are at least two potential problems to beware. First, always analyze
+the conflicts reported by Bison to make sure that GLR splitting is only
+done where it is intended. A GLR parser splitting inadvertently may
+cause problems less obvious than an LR parser statically choosing the
+wrong alternative in a conflict. Second, consider interactions with
+the lexer (*note Semantic Tokens::) with great care. Since a split
+parser consumes tokens without performing any actions during the split,
+the lexer cannot obtain information via parser actions. Some cases of
+lexer interactions can be eliminated by using GLR to shift the
+complications from the lexer to the parser. You must check the
+remaining cases for correctness.
+
+ In our example, it would be safe for the lexer to return tokens
+based on their current meanings in some symbol table, because no new
+symbols are defined in the middle of a type declaration. Though it is
+possible for a parser to define the enumeration constants as they are
+parsed, before the type declaration is completed, it actually makes no
+difference since they cannot be used within the same enumerated type
+declaration.

+
+1.5.2 Using GLR to Resolve Ambiguities
+--------------------------------------
+
+Let's consider an example, vastly simplified from a C++ grammar.
+
+ %{
+ #include <stdio.h>
+ #define YYSTYPE char const *
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+
+ %token TYPENAME ID
+
+ %right '='
+ %left '+'
+
+ %glr-parser
+
+ %%
+
+ prog:
+ /* Nothing. */
+ | prog stmt { printf ("\n"); }
+ ;
+
+ stmt:
+ expr ';' %dprec 1
+ | decl %dprec 2
+ ;
+
+ expr:
+ ID { printf ("%s ", $$); }
+ | TYPENAME '(' expr ')'
+ { printf ("%s <cast> ", $1); }
+ | expr '+' expr { printf ("+ "); }
+ | expr '=' expr { printf ("= "); }
+ ;
+
+ decl:
+ TYPENAME declarator ';'
+ { printf ("%s <declare> ", $1); }
+ | TYPENAME declarator '=' expr ';'
+ { printf ("%s <init-declare> ", $1); }
+ ;
+
+ declarator:
+ ID { printf ("\"%s\" ", $1); }
+ | '(' declarator ')'
+ ;
+
+This models a problematic part of the C++ grammar--the ambiguity between
+certain declarations and statements. For example,
+
+ T (x) = y+z;
+
+parses as either an `expr' or a `stmt' (assuming that `T' is recognized
+as a `TYPENAME' and `x' as an `ID'). Bison detects this as a
+reduce/reduce conflict between the rules `expr : ID' and `declarator :
+ID', which it cannot resolve at the time it encounters `x' in the
+example above. Since this is a GLR parser, it therefore splits the
+problem into two parses, one for each choice of resolving the
+reduce/reduce conflict. Unlike the example from the previous section
+(*note Simple GLR Parsers::), however, neither of these parses "dies,"
+because the grammar as it stands is ambiguous. One of the parsers
+eventually reduces `stmt : expr ';'' and the other reduces `stmt :
+decl', after which both parsers are in an identical state: they've seen
+`prog stmt' and have the same unprocessed input remaining. We say that
+these parses have "merged."
+
+ At this point, the GLR parser requires a specification in the
+grammar of how to choose between the competing parses. In the example
+above, the two `%dprec' declarations specify that Bison is to give
+precedence to the parse that interprets the example as a `decl', which
+implies that `x' is a declarator. The parser therefore prints
+
+ "x" y z + T <init-declare>
+
+ The `%dprec' declarations only come into play when more than one
+parse survives. Consider a different input string for this parser:
+
+ T (x) + y;
+
+This is another example of using GLR to parse an unambiguous construct,
+as shown in the previous section (*note Simple GLR Parsers::). Here,
+there is no ambiguity (this cannot be parsed as a declaration).
+However, at the time the Bison parser encounters `x', it does not have
+enough information to resolve the reduce/reduce conflict (again,
+between `x' as an `expr' or a `declarator'). In this case, no
+precedence declaration is used. Again, the parser splits into two, one
+assuming that `x' is an `expr', and the other assuming `x' is a
+`declarator'. The second of these parsers then vanishes when it sees
+`+', and the parser prints
+
+ x T <cast> y +
+
+ Suppose that instead of resolving the ambiguity, you wanted to see
+all the possibilities. For this purpose, you must merge the semantic
+actions of the two possible parsers, rather than choosing one over the
+other. To do so, you could change the declaration of `stmt' as follows:
+
+ stmt:
+ expr ';' %merge <stmtMerge>
+ | decl %merge <stmtMerge>
+ ;
+
+and define the `stmtMerge' function as:
+
+ static YYSTYPE
+ stmtMerge (YYSTYPE x0, YYSTYPE x1)
+ {
+ printf ("<OR> ");
+ return "";
+ }
+
+with an accompanying forward declaration in the C declarations at the
+beginning of the file:
+
+ %{
+ #define YYSTYPE char const *
+ static YYSTYPE stmtMerge (YYSTYPE x0, YYSTYPE x1);
+ %}
+
+With these declarations, the resulting parser parses the first example
+as both an `expr' and a `decl', and prints
+
+ "x" y z + T <init-declare> x T <cast> y z + = <OR>
+
+ Bison requires that all of the productions that participate in any
+particular merge have identical `%merge' clauses. Otherwise, the
+ambiguity would be unresolvable, and the parser will report an error
+during any parse that results in the offending merge.

+
+1.5.3 GLR Semantic Actions
+--------------------------
+
+By definition, a deferred semantic action is not performed at the same
+time as the associated reduction. This raises caveats for several
+Bison features you might use in a semantic action in a GLR parser.
+
+ In any semantic action, you can examine `yychar' to determine the
+type of the lookahead token present at the time of the associated
+reduction. After checking that `yychar' is not set to `YYEMPTY' or
+`YYEOF', you can then examine `yylval' and `yylloc' to determine the
+lookahead token's semantic value and location, if any. In a
+nondeferred semantic action, you can also modify any of these variables
+to influence syntax analysis. *Note Lookahead Tokens: Lookahead.
+
+ In a deferred semantic action, it's too late to influence syntax
+analysis. In this case, `yychar', `yylval', and `yylloc' are set to
+shallow copies of the values they had at the time of the associated
+reduction. For this reason alone, modifying them is dangerous.
+Moreover, the result of modifying them is undefined and subject to
+change with future versions of Bison. For example, if a semantic
+action might be deferred, you should never write it to invoke
+`yyclearin' (*note Action Features::) or to attempt to free memory
+referenced by `yylval'.
+
+ Another Bison feature requiring special consideration is `YYERROR'
+(*note Action Features::), which you can invoke in a semantic action to
+initiate error recovery. During deterministic GLR operation, the
+effect of `YYERROR' is the same as its effect in a deterministic parser.
+In a deferred semantic action, its effect is undefined.
+
+ Also, see *note Default Action for Locations: Location Default
+Action, which describes a special usage of `YYLLOC_DEFAULT' in GLR
+parsers.

+
+1.5.4 Considerations when Compiling GLR Parsers
+-----------------------------------------------
+
+The GLR parsers require a compiler for ISO C89 or later. In addition,
+they use the `inline' keyword, which is not C89, but is C99 and is a
+common extension in pre-C99 compilers. It is up to the user of these
+parsers to handle portability issues. For instance, if using Autoconf
+and the Autoconf macro `AC_C_INLINE', a mere
+
+ %{
+ #include <config.h>
+ %}
+
+will suffice. Otherwise, we suggest
+
+ %{
+ #if (__STDC_VERSION__ < 199901 && ! defined __GNUC__ \
+ && ! defined inline)
+ # define inline
+ #endif
+ %}
+
+\1f
+File: bison.info, Node: Locations, Next: Bison Parser, Prev: GLR Parsers, Up: Concepts
+
+1.6 Locations
+=============
+
+Many applications, like interpreters or compilers, have to produce
+verbose and useful error messages. To achieve this, one must be able
+to keep track of the "textual location", or "location", of each
+syntactic construct. Bison provides a mechanism for handling these
+locations.
+
+ Each token has a semantic value. In a similar fashion, each token
+has an associated location, but the type of locations is the same for
+all tokens and groupings. Moreover, the output parser is equipped with
+a default data structure for storing locations (*note Tracking
+Locations::, for more details).
+
+ Like semantic values, locations can be reached in actions using a
+dedicated set of constructs. In the example above, the location of the
+whole grouping is `@$', while the locations of the subexpressions are
+`@1' and `@3'.
+
+ When a rule is matched, a default action is used to compute the
+semantic value of its left hand side (*note Actions::). In the same
+way, another default action is used for locations. However, the action
+for locations is general enough for most cases, meaning there is
+usually no need to describe for each rule how `@$' should be formed.
+When building a new location for a given grouping, the default behavior
+of the output parser is to take the beginning of the first symbol, and
+the end of the last symbol.

+
+1.7 Bison Output: the Parser Implementation File
+================================================
+
+When you run Bison, you give it a Bison grammar file as input. The
+most important output is a C source file that implements a parser for
+the language described by the grammar. This parser is called a "Bison
+parser", and this file is called a "Bison parser implementation file".
+Keep in mind that the Bison utility and the Bison parser are two
+distinct programs: the Bison utility is a program whose output is the
+Bison parser implementation file that becomes part of your program.
+
+ The job of the Bison parser is to group tokens into groupings
+according to the grammar rules--for example, to build identifiers and
+operators into expressions. As it does this, it runs the actions for
+the grammar rules it uses.
+
+ The tokens come from a function called the "lexical analyzer" that
+you must supply in some fashion (such as by writing it in C). The Bison
+parser calls the lexical analyzer each time it wants a new token. It
+doesn't know what is "inside" the tokens (though their semantic values
+may reflect this). Typically the lexical analyzer makes the tokens by
+parsing characters of text, but Bison does not depend on this. *Note
+The Lexical Analyzer Function `yylex': Lexical.
+
+ The Bison parser implementation file is C code which defines a
+function named `yyparse' which implements that grammar. This function
+does not make a complete C program: you must supply some additional
+functions. One is the lexical analyzer. Another is an error-reporting
+function which the parser calls to report an error. In addition, a
+complete C program must start with a function called `main'; you have
+to provide this, and arrange for it to call `yyparse' or the parser
+will never run. *Note Parser C-Language Interface: Interface.
+
+ Aside from the token type names and the symbols in the actions you
+write, all symbols defined in the Bison parser implementation file
+itself begin with `yy' or `YY'. This includes interface functions such
+as the lexical analyzer function `yylex', the error reporting function
+`yyerror' and the parser function `yyparse' itself. This also includes
+numerous identifiers used for internal purposes. Therefore, you should
+avoid using C identifiers starting with `yy' or `YY' in the Bison
+grammar file except for the ones defined in this manual. Also, you
+should avoid using the C identifiers `malloc' and `free' for anything
+other than their usual meanings.
+
+ In some cases the Bison parser implementation file includes system
+headers, and in those cases your code should respect the identifiers
+reserved by those headers. On some non-GNU hosts, `<alloca.h>',
+`<malloc.h>', `<stddef.h>', and `<stdlib.h>' are included as needed to
+declare memory allocators and related types. `<libintl.h>' is included
+if message translation is in use (*note Internationalization::). Other
+system headers may be included if you define `YYDEBUG' to a nonzero
+value (*note Tracing Your Parser: Tracing.).
+
+\1f
+File: bison.info, Node: Stages, Next: Grammar Layout, Prev: Bison Parser, Up: Concepts
+
+1.8 Stages in Using Bison
+=========================
+
+The actual language-design process using Bison, from grammar
+specification to a working compiler or interpreter, has these parts:
+
+ 1. Formally specify the grammar in a form recognized by Bison (*note
+ Bison Grammar Files: Grammar File.). For each grammatical rule in
+ the language, describe the action that is to be taken when an
+ instance of that rule is recognized. The action is described by a
+ sequence of C statements.
+
+ 2. Write a lexical analyzer to process input and pass tokens to the
+ parser. The lexical analyzer may be written by hand in C (*note
+ The Lexical Analyzer Function `yylex': Lexical.). It could also
+ be produced using Lex, but the use of Lex is not discussed in this
+ manual.
+
+ 3. Write a controlling function that calls the Bison-produced parser.
+
+ 4. Write error-reporting routines.
+
+ To turn this source code as written into a runnable program, you
+must follow these steps:
+
+ 1. Run Bison on the grammar to produce the parser.
+
+ 2. Compile the code output by Bison, as well as any other source
+ files.
+
+ 3. Link the object files to produce the finished product.
+
+\1f
+File: bison.info, Node: Grammar Layout, Prev: Stages, Up: Concepts
+
+1.9 The Overall Layout of a Bison Grammar
+=========================================
+
+The input file for the Bison utility is a "Bison grammar file". The
+general form of a Bison grammar file is as follows:
+
+ %{
+ PROLOGUE
+ %}
+
+ BISON DECLARATIONS
+
+ %%
+ GRAMMAR RULES
+ %%
+ EPILOGUE
+
+The `%%', `%{' and `%}' are punctuation that appears in every Bison
+grammar file to separate the sections.
+
+ The prologue may define types and variables used in the actions.
+You can also use preprocessor commands to define macros used there, and
+use `#include' to include header files that do any of these things.
+You need to declare the lexical analyzer `yylex' and the error printer
+`yyerror' here, along with any other global identifiers used by the
+actions in the grammar rules.
+
+ The Bison declarations declare the names of the terminal and
+nonterminal symbols, and may also describe operator precedence and the
+data types of semantic values of various symbols.
+
+ The grammar rules define how to construct each nonterminal symbol
+from its parts.
+
+ The epilogue can contain any code you want to use. Often the
+definitions of functions declared in the prologue go here. In a simple
+program, all the rest of the program can go here.

+reverse polish notation calculator, an algebraic (infix) notation
+calculator -- later extended to track "locations" -- and a
+multi-function calculator. All produce usable, though limited,
+interactive desk-top calculators.

+languages are written the same way. You can copy these examples into a

+
+2.1.1 Declarations for `rpcalc'
+-------------------------------
+
+Here are the C and Bison declarations for the reverse polish notation
+calculator. As in C, comments are placed between `/*...*/'.
+
+ /* Reverse polish notation calculator. */
+
+ %{
+ #define YYSTYPE double
+ #include <math.h>
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+
+ %token NUM
+
+ %% /* Grammar rules and actions follow. */
+
+ The declarations section (*note The prologue: Prologue.) contains two
+preprocessor directives and two forward declarations.
+
+ The `#define' directive defines the macro `YYSTYPE', thus specifying
+the C data type for semantic values of both tokens and groupings (*note
+Data Types of Semantic Values: Value Type.). The Bison parser will use
+whatever type `YYSTYPE' is defined as; if you don't define it, `int' is
+the default. Because we specify `double', each token and each
+expression has an associated value, which is a floating point number.
+
+ The `#include' directive is used to declare the exponentiation
+function `pow'.
+
+ The forward declarations for `yylex' and `yyerror' are needed
+because the C language requires that functions be declared before they
+are used. These functions will be defined in the epilogue, but the
+parser calls them so they must be declared in the prologue.
+
+ The second section, Bison declarations, provides information to Bison
+about the token types (*note The Bison Declarations Section: Bison
+Declarations.). Each terminal symbol that is not a single-character
+literal must be declared here. (Single-character literals normally
+don't need to be declared.) In this example, all the arithmetic
+operators are designated by single-character literals, so the only
+terminal symbol that needs to be declared is `NUM', the token type for
+numeric constants.
+

+
+2.1.2 Grammar Rules for `rpcalc'
+--------------------------------
+
+Here are the grammar rules for the reverse polish notation calculator.
+
+ input:
+ /* empty */
+ | input line
+ ;
+
+ line:
+ '\n'
+ | exp '\n' { printf ("%.10g\n", $1); }
+ ;
+
+ exp:
+ NUM { $$ = $1; }
+ | exp exp '+' { $$ = $1 + $2; }
+ | exp exp '-' { $$ = $1 - $2; }
+ | exp exp '*' { $$ = $1 * $2; }
+ | exp exp '/' { $$ = $1 / $2; }
+ | exp exp '^' { $$ = pow ($1, $2); } /* Exponentiation */
+ | exp 'n' { $$ = -$1; } /* Unary minus */
+ ;
+ %%
+
+ The groupings of the rpcalc "language" defined here are the
+expression (given the name `exp'), the line of input (`line'), and the
+complete input transcript (`input'). Each of these nonterminal symbols
+has several alternate rules, joined by the vertical bar `|' which is
+read as "or". The following sections explain what these rules mean.
+
+ The semantics of the language is determined by the actions taken
+when a grouping is recognized. The actions are the C code that appears
+inside braces. *Note Actions::.
+
+ You must specify these actions in C, but Bison provides the means for
+passing semantic values between the rules. In each action, the
+pseudo-variable `$$' stands for the semantic value for the grouping
+that the rule is going to construct. Assigning a value to `$$' is the
+main job of most actions. The semantic values of the components of the
+rule are referred to as `$1', `$2', and so on.

+
+2.1.2.1 Explanation of `input'
+..............................
+
+Consider the definition of `input':
+
+ input:
+ /* empty */
+ | input line
+ ;
+
+ This definition reads as follows: "A complete input is either an
+empty string, or a complete input followed by an input line". Notice
+that "complete input" is defined in terms of itself. This definition
+is said to be "left recursive" since `input' appears always as the
+leftmost symbol in the sequence. *Note Recursive Rules: Recursion.
+
+ The first alternative is empty because there are no symbols between
+the colon and the first `|'; this means that `input' can match an empty
+string of input (no tokens). We write the rules this way because it is
+legitimate to type `Ctrl-d' right after you start the calculator. It's
+conventional to put an empty alternative first and write the comment
+`/* empty */' in it.
+
+ The second alternate rule (`input line') handles all nontrivial
+input. It means, "After reading any number of lines, read one more
+line if possible." The left recursion makes this rule into a loop.
+Since the first alternative matches empty input, the loop can be
+executed zero or more times.
+
+ The parser function `yyparse' continues to process input until a
+grammatical error is seen or the lexical analyzer says there are no more
+input tokens; we will arrange for the latter to happen at end-of-input.
+
+\1f
+File: bison.info, Node: Rpcalc Line, Next: Rpcalc Expr, Prev: Rpcalc Input, Up: Rpcalc Rules
+
+2.1.2.2 Explanation of `line'
+.............................
+
+Now consider the definition of `line':
+
+ line:
+ '\n'
+ | exp '\n' { printf ("%.10g\n", $1); }
+ ;
+
+ The first alternative is a token which is a newline character; this
+means that rpcalc accepts a blank line (and ignores it, since there is
+no action). The second alternative is an expression followed by a
+newline. This is the alternative that makes rpcalc useful. The
+semantic value of the `exp' grouping is the value of `$1' because the
+`exp' in question is the first symbol in the alternative. The action
+prints this value, which is the result of the computation the user
+asked for.
+
+ This action is unusual because it does not assign a value to `$$'.
+As a consequence, the semantic value associated with the `line' is
+uninitialized (its value will be unpredictable). This would be a bug if
+that value were ever used, but we don't use it: once rpcalc has printed
+the value of the user's input line, that value is no longer needed.
+
+\1f
+File: bison.info, Node: Rpcalc Expr, Prev: Rpcalc Line, Up: Rpcalc Rules
+
+2.1.2.3 Explanation of `expr'
+.............................
+
+The `exp' grouping has several rules, one for each kind of expression.
+The first rule handles the simplest expressions: those that are just
+numbers. The second handles an addition-expression, which looks like
+two expressions followed by a plus-sign. The third handles
+subtraction, and so on.
+
+ exp:
+ NUM
+ | exp exp '+' { $$ = $1 + $2; }
+ | exp exp '-' { $$ = $1 - $2; }
+ ...
+ ;
+
+ We have used `|' to join all the rules for `exp', but we could
+equally well have written them separately:
+
+ exp: NUM ;
+ exp: exp exp '+' { $$ = $1 + $2; };
+ exp: exp exp '-' { $$ = $1 - $2; };
+ ...
+
+ Most of the rules have actions that compute the value of the
+expression in terms of the value of its parts. For example, in the
+rule for addition, `$1' refers to the first component `exp' and `$2'
+refers to the second one. The third component, `'+'', has no meaningful
+associated semantic value, but if it had one you could refer to it as
+`$3'. When `yyparse' recognizes a sum expression using this rule, the
+sum of the two subexpressions' values is produced as the value of the
+entire expression. *Note Actions::.
+
+ You don't have to give an action for every rule. When a rule has no
+action, Bison by default copies the value of `$1' into `$$'. This is
+what happens in the first rule (the one that uses `NUM').
+
+ The formatting shown here is the recommended convention, but Bison
+does not require it. You can add or change white space as much as you
+wish. For example, this:
+
+ exp: NUM | exp exp '+' {$$ = $1 + $2; } | ... ;
+
+means the same thing as this:
+
+ exp:
+ NUM
+ | exp exp '+' { $$ = $1 + $2; }
+ | ...
+ ;
+
+The latter, however, is much more readable.
+
+\1f
+File: bison.info, Node: Rpcalc Lexer, Next: Rpcalc Main, Prev: Rpcalc Rules, Up: RPN Calc
+
+2.1.3 The `rpcalc' Lexical Analyzer
+-----------------------------------
+
+The lexical analyzer's job is low-level parsing: converting characters
+or sequences of characters into tokens. The Bison parser gets its
+tokens by calling the lexical analyzer. *Note The Lexical Analyzer
+Function `yylex': Lexical.
+
+ Only a simple lexical analyzer is needed for the RPN calculator.
+This lexical analyzer skips blanks and tabs, then reads in numbers as
+`double' and returns them as `NUM' tokens. Any other character that
+isn't part of a number is a separate token. Note that the token-code
+for such a single-character token is the character itself.
+
+ The return value of the lexical analyzer function is a numeric code
+which represents a token type. The same text used in Bison rules to
+stand for this token type is also a C expression for the numeric code
+for the type. This works in two ways. If the token type is a
+character literal, then its numeric code is that of the character; you
+can use the same character literal in the lexical analyzer to express
+the number. If the token type is an identifier, that identifier is
+defined by Bison as a C macro whose definition is the appropriate
+number. In this example, therefore, `NUM' becomes a macro for `yylex'
+to use.
+
+ The semantic value of the token (if it has one) is stored into the
+global variable `yylval', which is where the Bison parser will look for
+it. (The C data type of `yylval' is `YYSTYPE', which was defined at
+the beginning of the grammar; *note Declarations for `rpcalc': Rpcalc
+Declarations.)
+
+ A token type code of zero is returned if the end-of-input is
+encountered. (Bison recognizes any nonpositive value as indicating
+end-of-input.)
+
+ Here is the code for the lexical analyzer:
+
+ /* The lexical analyzer returns a double floating point
+ number on the stack and the token NUM, or the numeric code
+ of the character read if not a number. It skips all blanks
+ and tabs, and returns 0 for end-of-input. */
+
+ #include <ctype.h>
+
+ int
+ yylex (void)
+ {
+ int c;
+
+ /* Skip white space. */
+ while ((c = getchar ()) == ' ' || c == '\t')
+ continue;
+ /* Process numbers. */
+ if (c == '.' || isdigit (c))
+ {
+ ungetc (c, stdin);
+ scanf ("%lf", &yylval);
+ return NUM;
+ }
+ /* Return end-of-input. */
+ if (c == EOF)
+ return 0;
+ /* Return a single char. */
+ return c;
+ }

+
+2.1.4 The Controlling Function
+------------------------------
+
+In keeping with the spirit of this example, the controlling function is
+kept to the bare minimum. The only requirement is that it call
+`yyparse' to start the process of parsing.
+
+ int
+ main (void)
+ {
+ return yyparse ();
+ }
+
+\1f
+File: bison.info, Node: Rpcalc Error, Next: Rpcalc Generate, Prev: Rpcalc Main, Up: RPN Calc
+
+2.1.5 The Error Reporting Routine
+---------------------------------
+
+When `yyparse' detects a syntax error, it calls the error reporting
+function `yyerror' to print an error message (usually but not always
+`"syntax error"'). It is up to the programmer to supply `yyerror'
+(*note Parser C-Language Interface: Interface.), so here is the
+definition we will use:
+
+ #include <stdio.h>
+
+ /* Called by yyparse on error. */
+ void
+ yyerror (char const *s)
+ {
+ fprintf (stderr, "%s\n", s);
+ }
+
+ After `yyerror' returns, the Bison parser may recover from the error
+and continue parsing if the grammar contains a suitable error rule
+(*note Error Recovery::). Otherwise, `yyparse' returns nonzero. We
+have not written any error rules in this example, so any invalid input
+will cause the calculator program to exit. This is not clean behavior
+for a real calculator, but it is adequate for the first example.
+

+
+2.1.6 Running Bison to Make the Parser
+--------------------------------------
+
+Before running Bison to produce a parser, we need to decide how to
+arrange all the source code in one or more source files. For such a
+simple example, the easiest thing is to put everything in one file, the
+grammar file. The definitions of `yylex', `yyerror' and `main' go at
+the end, in the epilogue of the grammar file (*note The Overall Layout
+of a Bison Grammar: Grammar Layout.).
+
+ For a large project, you would probably have several source files,
+and use `make' to arrange to recompile them.
+
+ With all the source in the grammar file, you use the following
+command to convert it into a parser implementation file:
+
+ bison FILE.y
+
+In this example, the grammar file is called `rpcalc.y' (for "Reverse
+Polish CALCulator"). Bison produces a parser implementation file named
+`FILE.tab.c', removing the `.y' from the grammar file name. The parser
+implementation file contains the source code for `yyparse'. The
+additional functions in the grammar file (`yylex', `yyerror' and
+`main') are copied verbatim to the parser implementation file.

+
+2.1.7 Compiling the Parser Implementation File
+----------------------------------------------
+
+Here is how to compile and run the parser implementation file:
+
+ # List files in current directory.
+ $ ls
+ rpcalc.tab.c rpcalc.y
+
+ # Compile the Bison parser.
+ # `-lm' tells compiler to search math library for `pow'.
+ $ cc -lm -o rpcalc rpcalc.tab.c
+

+2.2 Infix Notation Calculator: `calc'
+=====================================
+
+We now modify rpcalc to handle infix operators instead of postfix.
+Infix notation involves the concept of operator precedence and the need
+for parentheses nested to arbitrary depth. Here is the Bison code for
+`calc.y', an infix desk-top calculator.
+
+ /* Infix notation calculator. */
+
+ %{
+ #define YYSTYPE double
+ #include <math.h>
+ #include <stdio.h>
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+
+ /* Bison declarations. */
+ %token NUM
+ %left '-' '+'
+ %left '*' '/'
+ %left NEG /* negation--unary minus */
+ %right '^' /* exponentiation */
+
+ %% /* The grammar follows. */
+ input:
+ /* empty */
+ | input line
+ ;
+
+ line:
+ '\n'
+ | exp '\n' { printf ("\t%.10g\n", $1); }
+ ;
+
+ exp:
+ NUM { $$ = $1; }
+ | exp '+' exp { $$ = $1 + $3; }
+ | exp '-' exp { $$ = $1 - $3; }
+ | exp '*' exp { $$ = $1 * $3; }
+ | exp '/' exp { $$ = $1 / $3; }
+ | '-' exp %prec NEG { $$ = -$2; }
+ | exp '^' exp { $$ = pow ($1, $3); }
+ | '(' exp ')' { $$ = $2; }
+ ;
+ %%
+
+The functions `yylex', `yyerror' and `main' can be the same as before.
+
+ There are two important new features shown in this code.
+
+ In the second section (Bison declarations), `%left' declares token
+types and says they are left-associative operators. The declarations
+`%left' and `%right' (right associativity) take the place of `%token'
+which is used to declare a token type name without associativity.
+(These tokens are single-character literals, which ordinarily don't
+need to be declared. We declare them here to specify the
+associativity.)
+
+ Operator precedence is determined by the line ordering of the
+declarations; the higher the line number of the declaration (lower on
+the page or screen), the higher the precedence. Hence, exponentiation
+has the highest precedence, unary minus (`NEG') is next, followed by
+`*' and `/', and so on. *Note Operator Precedence: Precedence.
+
+ The other important new feature is the `%prec' in the grammar
+section for the unary minus operator. The `%prec' simply instructs
+Bison that the rule `| '-' exp' has the same precedence as `NEG'--in
+this case the next-to-highest. *Note Context-Dependent Precedence:
+Contextual Precedence.
+
+ Here is a sample run of `calc.y':
+
+ $ calc
+ 4 + 4.5 - (34/(8*3+-3))
+ 6.880952381
+ -56 + 2

+
+2.3 Simple Error Recovery
+=========================
+
+Up to this point, this manual has not addressed the issue of "error
+recovery"--how to continue parsing after the parser detects a syntax
+error. All we have handled is error reporting with `yyerror'. Recall
+that by default `yyparse' returns after calling `yyerror'. This means
+that an erroneous input line causes the calculator program to exit.
+Now we show how to rectify this deficiency.
+
+ The Bison language itself includes the reserved word `error', which
+may be included in the grammar rules. In the example below it has been
+added to one of the alternatives for `line':
+
+ line:
+ '\n'
+ | exp '\n' { printf ("\t%.10g\n", $1); }
+ | error '\n' { yyerrok; }
+ ;
+
+ This addition to the grammar allows for simple error recovery in the
+event of a syntax error. If an expression that cannot be evaluated is
+read, the error will be recognized by the third rule for `line', and
+parsing will continue. (The `yyerror' function is still called upon to
+print its message as well.) The action executes the statement
+`yyerrok', a macro defined automatically by Bison; its meaning is that
+error recovery is complete (*note Error Recovery::). Note the
+difference between `yyerrok' and `yyerror'; neither one is a misprint.
+
+ This form of error recovery deals with syntax errors. There are
+other kinds of errors; for example, division by zero, which raises an
+exception signal that is normally fatal. A real calculator program
+must handle this signal and use `longjmp' to return to `main' and
+resume parsing input lines; it would also have to discard the rest of
+the current line of input. We won't discuss this issue further because
+it is not specific to Bison programs.
+

+
+2.4 Location Tracking Calculator: `ltcalc'
+==========================================
+
+This example extends the infix notation calculator with location
+tracking. This feature will be used to improve the error messages. For
+the sake of clarity, this example is a simple integer calculator, since
+most of the work needed to use locations will be done in the lexical
+analyzer.

+* Ltcalc Rules:: Grammar rules for ltcalc, with explanations.
+* Ltcalc Lexer:: The lexical analyzer.
+
+\1f
+File: bison.info, Node: Ltcalc Declarations, Next: Ltcalc Rules, Up: Location Tracking Calc
+
+2.4.1 Declarations for `ltcalc'
+-------------------------------
+
+The C and Bison declarations for the location tracking calculator are
+the same as the declarations for the infix notation calculator.
+
+ /* Location tracking calculator. */
+
+ %{
+ #define YYSTYPE int
+ #include <math.h>
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+
+ /* Bison declarations. */
+ %token NUM
+
+ %left '-' '+'
+ %left '*' '/'
+ %left NEG
+ %right '^'
+
+ %% /* The grammar follows. */
+
+Note there are no declarations specific to locations. Defining a data
+type for storing locations is not needed: we will use the type provided
+by default (*note Data Types of Locations: Location Type.), which is a
+four member structure with the following integer fields: `first_line',
+`first_column', `last_line' and `last_column'. By conventions, and in
+accordance with the GNU Coding Standards and common practice, the line
+and column count both start at 1.
+

+
+2.4.2 Grammar Rules for `ltcalc'
+--------------------------------
+
+Whether handling locations or not has no effect on the syntax of your
+language. Therefore, grammar rules for this example will be very close
+to those of the previous example: we will only modify them to benefit
+from the new information.
+
+ Here, we will use locations to report divisions by zero, and locate
+the wrong expressions or subexpressions.
+
+ input:
+ /* empty */
+ | input line
+ ;
+
+ line:
+ '\n'
+ | exp '\n' { printf ("%d\n", $1); }
+ ;
+
+ exp:
+ NUM { $$ = $1; }
+ | exp '+' exp { $$ = $1 + $3; }
+ | exp '-' exp { $$ = $1 - $3; }
+ | exp '*' exp { $$ = $1 * $3; }
+ | exp '/' exp
+ {
+ if ($3)
+ $$ = $1 / $3;
+ else
+ {
+ $$ = 1;
+ fprintf (stderr, "%d.%d-%d.%d: division by zero",
+ @3.first_line, @3.first_column,
+ @3.last_line, @3.last_column);
+ }
+ }
+ | '-' exp %prec NEG { $$ = -$2; }
+ | exp '^' exp { $$ = pow ($1, $3); }
+ | '(' exp ')' { $$ = $2; }
+
+ This code shows how to reach locations inside of semantic actions, by
+using the pseudo-variables `@N' for rule components, and the
+pseudo-variable `@$' for groupings.
+
+ We don't need to assign a value to `@$': the output parser does it
+automatically. By default, before executing the C code of each action,
+`@$' is set to range from the beginning of `@1' to the end of `@N', for
+a rule with N components. This behavior can be redefined (*note
+Default Action for Locations: Location Default Action.), and for very
+specific rules, `@$' can be computed by hand.
+

+
+2.4.3 The `ltcalc' Lexical Analyzer.
+------------------------------------
+
+Until now, we relied on Bison's defaults to enable location tracking.
+The next step is to rewrite the lexical analyzer, and make it able to
+feed the parser with the token locations, as it already does for
+semantic values.
+
+ To this end, we must take into account every single character of the
+input text, to avoid the computed locations of being fuzzy or wrong:
+
+ int
+ yylex (void)
+ {
+ int c;
+
+ /* Skip white space. */
+ while ((c = getchar ()) == ' ' || c == '\t')
+ ++yylloc.last_column;
+
+ /* Step. */
+ yylloc.first_line = yylloc.last_line;
+ yylloc.first_column = yylloc.last_column;
+
+ /* Process numbers. */
+ if (isdigit (c))
+ {
+ yylval = c - '0';
+ ++yylloc.last_column;
+ while (isdigit (c = getchar ()))
+ {
+ ++yylloc.last_column;
+ yylval = yylval * 10 + c - '0';
+ }
+ ungetc (c, stdin);
+ return NUM;
+ }
+
+ /* Return end-of-input. */
+ if (c == EOF)
+ return 0;
+
+ /* Return a single char, and update location. */
+ if (c == '\n')
+ {
+ ++yylloc.last_line;
+ yylloc.last_column = 0;
+ }
+ else
+ ++yylloc.last_column;
+ return c;
+ }
+
+ Basically, the lexical analyzer performs the same processing as
+before: it skips blanks and tabs, and reads numbers or single-character
+tokens. In addition, it updates `yylloc', the global variable (of type
+`YYLTYPE') containing the token's location.
+
+ Now, each time this function returns a token, the parser has its
+number as well as its semantic value, and its location in the text.
+The last needed change is to initialize `yylloc', for example in the
+controlling function:
+
+ int
+ main (void)
+ {
+ yylloc.first_line = yylloc.last_line = 1;
+ yylloc.first_column = yylloc.last_column = 0;
+ return yyparse ();
+ }
+
+ Remember that computing locations is not a matter of syntax. Every
+character must be associated to a location update, whether it is in
+valid input, in comments, in literal strings, and so on.

+2.5 Multi-Function Calculator: `mfcalc'
+=======================================
+
+Now that the basics of Bison have been discussed, it is time to move on
+to a more advanced problem. The above calculators provided only five
+functions, `+', `-', `*', `/' and `^'. It would be nice to have a
+calculator that provides other mathematical functions such as `sin',
+`cos', etc.
+
+ It is easy to add new operators to the infix calculator as long as
+they are only single-character literals. The lexical analyzer `yylex'
+passes back all nonnumeric characters as tokens, so new grammar rules
+suffice for adding a new operator. But we want something more
+flexible: built-in functions whose syntax has this form:
+
+ FUNCTION_NAME (ARGUMENT)
+
+At the same time, we will add memory to the calculator, by allowing you
+to create named variables, store values in them, and use them later.
+Here is a sample session with the multi-function calculator:
+
+ $ mfcalc
+ pi = 3.141592653589
+ 3.1415926536
+ sin(pi)
+ 0.0000000000
+ alpha = beta1 = 2.3
+ 2.3000000000
+ alpha
+ 2.3000000000
+ ln(alpha)
+ 0.8329091229
+ exp(ln(beta1))
+ 2.3000000000
+ $
+
+ Note that multiple assignment and nested function calls are
+permitted.

+
+2.5.1 Declarations for `mfcalc'
+-------------------------------
+
+Here are the C and Bison declarations for the multi-function calculator.
+
+ %{
+ #include <math.h> /* For math functions, cos(), sin(), etc. */
+ #include "calc.h" /* Contains definition of `symrec'. */
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+
+ %union {
+ double val; /* For returning numbers. */
+ symrec *tptr; /* For returning symbol-table pointers. */
+ }
+ %token <val> NUM /* Simple double precision number. */
+ %token <tptr> VAR FNCT /* Variable and function. */
+ %type <val> exp
+
+ %right '='
+ %left '-' '+'
+ %left '*' '/'
+ %left NEG /* negation--unary minus */
+ %right '^' /* exponentiation */
+
+ The above grammar introduces only two new features of the Bison
+language. These features allow semantic values to have various data
+types (*note More Than One Value Type: Multiple Types.).
+
+ The `%union' declaration specifies the entire list of possible types;
+this is instead of defining `YYSTYPE'. The allowable types are now
+double-floats (for `exp' and `NUM') and pointers to entries in the
+symbol table. *Note The Collection of Value Types: Union Decl.
+
+ Since values can now have various types, it is necessary to
+associate a type with each grammar symbol whose semantic value is used.
+These symbols are `NUM', `VAR', `FNCT', and `exp'. Their declarations
+are augmented with information about their data type (placed between
+angle brackets).
+
+ The Bison construct `%type' is used for declaring nonterminal
+symbols, just as `%token' is used for declaring token types. We have
+not used `%type' before because nonterminal symbols are normally
+declared implicitly by the rules that define them. But `exp' must be
+declared explicitly so we can specify its value type. *Note
+Nonterminal Symbols: Type Decl.

+ | exp '+' exp { $$ = $1 + $3; }
+ | exp '-' exp { $$ = $1 - $3; }
+ | exp '*' exp { $$ = $1 * $3; }
+ | exp '/' exp { $$ = $1 / $3; }
+ | '-' exp %prec NEG { $$ = -$2; }
+ | exp '^' exp { $$ = pow ($1, $3); }
+ | '(' exp ')' { $$ = $2; }
+ ;
+ /* End of grammar. */

+File: bison.info, Node: Mfcalc Symbol Table, Prev: Mfcalc Rules, Up: Multi-function Calc
+
+2.5.3 The `mfcalc' Symbol Table
+-------------------------------
+
+The multi-function calculator requires a symbol table to keep track of
+the names and meanings of variables and functions. This doesn't affect
+the grammar rules (except for the actions) or the Bison declarations,
+but it requires some additional C functions for support.
+
+ The symbol table itself consists of a linked list of records. Its
+definition, which is kept in the header `calc.h', is as follows. It
+provides for either functions or variables to be placed in the table.
+
+ /* Function type. */
+ typedef double (*func_t) (double);
+
+ /* Data type for links in the chain of symbols. */
+ struct symrec
+ {
+ char *name; /* name of symbol */
+ int type; /* type of symbol: either VAR or FNCT */
+ union
+ {
+ double var; /* value of a VAR */
+ func_t fnctptr; /* value of a FNCT */
+ } value;
+ struct symrec *next; /* link field */
+ };
+
+ typedef struct symrec symrec;
+
+ /* The symbol table: a chain of `struct symrec'. */
+ extern symrec *sym_table;
+
+ symrec *putsym (char const *, int);
+ symrec *getsym (char const *);
+
+ The new version of `main' includes a call to `init_table', a
+function that initializes the symbol table. Here it is, and
+`init_table' as well:
+
+ #include <stdio.h>
+
+ /* Called by yyparse on error. */
+ void
+ yyerror (char const *s)
+ {
+ printf ("%s\n", s);
+ }
+
+ struct init
+ {
+ char const *fname;
+ double (*fnct) (double);
+ };
+
+ struct init const arith_fncts[] =
+ {
+ "sin", sin,
+ "cos", cos,
+ "atan", atan,
+ "ln", log,
+ "exp", exp,
+ "sqrt", sqrt,
+ 0, 0
+ };
+
+ /* The symbol table: a chain of `struct symrec'. */
+ symrec *sym_table;
+
+ /* Put arithmetic functions in table. */
+ void
+ init_table (void)
+ {
+ int i;
+ for (i = 0; arith_fncts[i].fname != 0; i++)
+ {
+ symrec *ptr = putsym (arith_fncts[i].fname, FNCT);
+ ptr->value.fnctptr = arith_fncts[i].fnct;
+ }
+ }
+
+ int
+ main (void)
+ {
+ init_table ();
+ return yyparse ();
+ }
+
+ By simply editing the initialization list and adding the necessary
+include files, you can add additional functions to the calculator.
+
+ Two important functions allow look-up and installation of symbols in
+the symbol table. The function `putsym' is passed a name and the type
+(`VAR' or `FNCT') of the object to be installed. The object is linked
+to the front of the list, and a pointer to the object is returned. The
+function `getsym' is passed the name of the symbol to look up. If
+found, a pointer to that symbol is returned; otherwise zero is returned.
+
+ #include <stdlib.h> /* malloc. */
+ #include <string.h> /* strlen. */
+
+ symrec *
+ putsym (char const *sym_name, int sym_type)
+ {
+ symrec *ptr = (symrec *) malloc (sizeof (symrec));
+ ptr->name = (char *) malloc (strlen (sym_name) + 1);
+ strcpy (ptr->name,sym_name);
+ ptr->type = sym_type;
+ ptr->value.var = 0; /* Set value to 0 even if fctn. */
+ ptr->next = (struct symrec *)sym_table;
+ sym_table = ptr;
+ return ptr;
+ }
+
+ symrec *
+ getsym (char const *sym_name)
+ {
+ symrec *ptr;
+ for (ptr = sym_table; ptr != (symrec *) 0;
+ ptr = (symrec *)ptr->next)
+ if (strcmp (ptr->name,sym_name) == 0)
+ return ptr;
+ return 0;
+ }
+
+ The function `yylex' must now recognize variables, numeric values,
+and the single-character arithmetic operators. Strings of alphanumeric
+characters with a leading letter are recognized as either variables or
+functions depending on what the symbol table says about them.
+
+ The string is passed to `getsym' for look up in the symbol table. If
+the name appears in the table, a pointer to its location and its type
+(`VAR' or `FNCT') is returned to `yyparse'. If it is not already in
+the table, then it is installed as a `VAR' using `putsym'. Again, a
+pointer and its type (which must be `VAR') is returned to `yyparse'.
+
+ No change is needed in the handling of numeric values and arithmetic
+operators in `yylex'.
+
+ #include <ctype.h>
+
+ int
+ yylex (void)
+ {
+ int c;
+
+ /* Ignore white space, get first nonwhite character. */
+ while ((c = getchar ()) == ' ' || c == '\t')
+ continue;
+
+ if (c == EOF)
+ return 0;
+
+ /* Char starts a number => parse the number. */
+ if (c == '.' || isdigit (c))
+ {
+ ungetc (c, stdin);
+ scanf ("%lf", &yylval.val);
+ return NUM;
+ }
+
+ /* Char starts an identifier => read the name. */
+ if (isalpha (c))
+ {
+ /* Initially make the buffer long enough
+ for a 40-character symbol name. */
+ static size_t length = 40;
+ static char *symbuf = 0;
+ symrec *s;
+ int i;
+
+ if (!symbuf)
+ symbuf = (char *) malloc (length + 1);
+
+ i = 0;
+ do
+ {
+ /* If buffer is full, make it bigger. */
+ if (i == length)
+ {
+ length *= 2;
+ symbuf = (char *) realloc (symbuf, length + 1);
+ }
+ /* Add this character to the buffer. */
+ symbuf[i++] = c;
+ /* Get another character. */
+ c = getchar ();
+ }
+ while (isalnum (c));
+
+ ungetc (c, stdin);
+ symbuf[i] = '\0';
+
+ s = getsym (symbuf);
+ if (s == 0)
+ s = putsym (symbuf, VAR);
+ yylval.tptr = s;
+ return s->type;
+ }
+
+ /* Any other character is a token by itself. */
+ return c;
+ }
+
+ The error reporting function is unchanged, and the new version of
+`main' includes a call to `init_table' and sets the `yydebug' on user
+demand (*Note Tracing Your Parser: Tracing, for details):
+
+ /* Called by yyparse on error. */
+ void
+ yyerror (char const *s)
+ {
+ fprintf (stderr, "%s\n", s);
+ }
+
+ int
+ main (int argc, char const* argv[])
+ {
+ int i;
+ /* Enable parse traces on option -p. */
+ for (i = 1; i < argc; ++i)
+ if (!strcmp(argv[i], "-p"))
+ yydebug = 1;
+ init_table ();
+ return yyparse ();
+ }
+
+ This program is both powerful and flexible. You may easily add new
+functions, and it is a simple job to modify this code to install
+predefined variables such as `pi' or `e' as well.

+------------------
+
+The PROLOGUE section contains macro definitions and declarations of

+rules. These are copied to the beginning of the parser implementation
+file so that they precede the definition of `yyparse'. You can use
+`#include' to get the declarations from a header file. If you don't
+need any C declarations, you may omit the `%{' and `%}' delimiters that
+bracket this section.
+
+ The PROLOGUE section is terminated by the first occurrence of `%}'
+that is outside a comment, a string literal, or a character constant.
+
+ You may have more than one PROLOGUE section, intermixed with the
+BISON DECLARATIONS. This allows you to have C and Bison declarations
+that refer to each other. For example, the `%union' declaration may
+use types defined in a header file, and you may wish to prototype
+functions that take arguments of type `YYSTYPE'. This can be done with
+two PROLOGUE blocks, one before and one after the `%union' declaration.
+
+ %{
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ #include "ptypes.h"
+ %}
+
+ %union {
+ long int n;
+ tree t; /* `tree' is defined in `ptypes.h'. */
+ }
+
+ %{
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ %}
+
+ ...
+
+ When in doubt, it is usually safer to put prologue code before all
+Bison declarations, rather than after. For example, any definitions of
+feature test macros like `_GNU_SOURCE' or `_POSIX_C_SOURCE' should
+appear before all Bison declarations, as feature test macros can affect
+the behavior of Bison-generated `#include' directives.

+
+3.1.2 Prologue Alternatives
+---------------------------
+
+The functionality of PROLOGUE sections can often be subtle and
+inflexible. As an alternative, Bison provides a `%code' directive with
+an explicit qualifier field, which identifies the purpose of the code
+and thus the location(s) where Bison should generate it. For C/C++,
+the qualifier can be omitted for the default location, or it can be one
+of `requires', `provides', `top'. *Note %code Summary::.
+
+ Look again at the example of the previous section:
+
+ %{
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ #include "ptypes.h"
+ %}
+
+ %union {
+ long int n;
+ tree t; /* `tree' is defined in `ptypes.h'. */
+ }
+
+ %{
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ %}
+
+ ...
+
+Notice that there are two PROLOGUE sections here, but there's a subtle
+distinction between their functionality. For example, if you decide to
+override Bison's default definition for `YYLTYPE', in which PROLOGUE
+section should you write your new definition? You should write it in
+the first since Bison will insert that code into the parser
+implementation file _before_ the default `YYLTYPE' definition. In
+which PROLOGUE section should you prototype an internal function,
+`trace_token', that accepts `YYLTYPE' and `yytokentype' as arguments?
+You should prototype it in the second since Bison will insert that code
+_after_ the `YYLTYPE' and `yytokentype' definitions.
+
+ This distinction in functionality between the two PROLOGUE sections
+is established by the appearance of the `%union' between them. This
+behavior raises a few questions. First, why should the position of a
+`%union' affect definitions related to `YYLTYPE' and `yytokentype'?
+Second, what if there is no `%union'? In that case, the second kind of
+PROLOGUE section is not available. This behavior is not intuitive.
+
+ To avoid this subtle `%union' dependency, rewrite the example using a
+`%code top' and an unqualified `%code'. Let's go ahead and add the new
+`YYLTYPE' definition and the `trace_token' prototype at the same time:
+
+ %code top {
+ #define _GNU_SOURCE
+ #include <stdio.h>
+
+ /* WARNING: The following code really belongs
+ * in a `%code requires'; see below. */
+
+ #include "ptypes.h"
+ #define YYLTYPE YYLTYPE
+ typedef struct YYLTYPE
+ {
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+ char *filename;
+ } YYLTYPE;
+ }
+
+ %union {
+ long int n;
+ tree t; /* `tree' is defined in `ptypes.h'. */
+ }
+
+ %code {
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ static void trace_token (enum yytokentype token, YYLTYPE loc);
+ }
+
+ ...
+
+In this way, `%code top' and the unqualified `%code' achieve the same
+functionality as the two kinds of PROLOGUE sections, but it's always
+explicit which kind you intend. Moreover, both kinds are always
+available even in the absence of `%union'.
+
+ The `%code top' block above logically contains two parts. The first
+two lines before the warning need to appear near the top of the parser
+implementation file. The first line after the warning is required by
+`YYSTYPE' and thus also needs to appear in the parser implementation
+file. However, if you've instructed Bison to generate a parser header
+file (*note %defines: Decl Summary.), you probably want that line to
+appear before the `YYSTYPE' definition in that header file as well.
+The `YYLTYPE' definition should also appear in the parser header file
+to override the default `YYLTYPE' definition there.
+
+ In other words, in the `%code top' block above, all but the first two
+lines are dependency code required by the `YYSTYPE' and `YYLTYPE'
+definitions. Thus, they belong in one or more `%code requires':
+
+ %code top {
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ }
+
+ %code requires {
+ #include "ptypes.h"
+ }
+ %union {
+ long int n;
+ tree t; /* `tree' is defined in `ptypes.h'. */
+ }
+
+ %code requires {
+ #define YYLTYPE YYLTYPE
+ typedef struct YYLTYPE
+ {
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+ char *filename;
+ } YYLTYPE;
+ }
+
+ %code {
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ static void trace_token (enum yytokentype token, YYLTYPE loc);
+ }
+
+ ...
+
+Now Bison will insert `#include "ptypes.h"' and the new `YYLTYPE'
+definition before the Bison-generated `YYSTYPE' and `YYLTYPE'
+definitions in both the parser implementation file and the parser
+header file. (By the same reasoning, `%code requires' would also be
+the appropriate place to write your own definition for `YYSTYPE'.)
+
+ When you are writing dependency code for `YYSTYPE' and `YYLTYPE',
+you should prefer `%code requires' over `%code top' regardless of
+whether you instruct Bison to generate a parser header file. When you
+are writing code that you need Bison to insert only into the parser
+implementation file and that has no special need to appear at the top
+of that file, you should prefer the unqualified `%code' over `%code
+top'. These practices will make the purpose of each block of your code
+explicit to Bison and to other developers reading your grammar file.
+Following these practices, we expect the unqualified `%code' and `%code
+requires' to be the most important of the four PROLOGUE alternatives.
+
+ At some point while developing your parser, you might decide to
+provide `trace_token' to modules that are external to your parser.
+Thus, you might wish for Bison to insert the prototype into both the
+parser header file and the parser implementation file. Since this
+function is not a dependency required by `YYSTYPE' or `YYLTYPE', it
+doesn't make sense to move its prototype to a `%code requires'. More
+importantly, since it depends upon `YYLTYPE' and `yytokentype', `%code
+requires' is not sufficient. Instead, move its prototype from the
+unqualified `%code' to a `%code provides':
+
+ %code top {
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ }
+
+ %code requires {
+ #include "ptypes.h"
+ }
+ %union {
+ long int n;
+ tree t; /* `tree' is defined in `ptypes.h'. */
+ }
+
+ %code requires {
+ #define YYLTYPE YYLTYPE
+ typedef struct YYLTYPE
+ {
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+ char *filename;
+ } YYLTYPE;
+ }
+
+ %code provides {
+ void trace_token (enum yytokentype token, YYLTYPE loc);
+ }
+
+ %code {
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ }
+
+ ...
+
+Bison will insert the `trace_token' prototype into both the parser
+header file and the parser implementation file after the definitions
+for `yytokentype', `YYLTYPE', and `YYSTYPE'.
+
+ The above examples are careful to write directives in an order that
+reflects the layout of the generated parser implementation and header
+files: `%code top', `%code requires', `%code provides', and then
+`%code'. While your grammar files may generally be easier to read if
+you also follow this order, Bison does not require it. Instead, Bison
+lets you choose an organization that makes sense to you.
+
+ You may declare any of these directives multiple times in the
+grammar file. In that case, Bison concatenates the contained code in
+declaration order. This is the only way in which the position of one
+of these directives within the grammar file affects its functionality.
+
+ The result of the previous two properties is greater flexibility in
+how you may organize your grammar file. For example, you may organize
+semantic-type-related directives by semantic type:
+
+ %code requires { #include "type1.h" }
+ %union { type1 field1; }
+ %destructor { type1_free ($$); } <field1>
+ %printer { type1_print (yyoutput, $$); } <field1>
+
+ %code requires { #include "type2.h" }
+ %union { type2 field2; }
+ %destructor { type2_free ($$); } <field2>
+ %printer { type2_print (yyoutput, $$); } <field2>
+
+You could even place each of the above directive groups in the rules
+section of the grammar file next to the set of rules that uses the
+associated semantic type. (In the rules section, you must terminate
+each of those directives with a semicolon.) And you don't have to
+worry that some directive (like a `%union') in the definitions section
+is going to adversely affect their functionality in some
+counter-intuitive manner just because it comes first. Such an
+organization is not possible using PROLOGUE sections.
+
+ This section has been concerned with explaining the advantages of
+the four PROLOGUE alternatives over the original Yacc PROLOGUE.
+However, in most cases when using these directives, you shouldn't need
+to think about all the low-level ordering issues discussed here.
+Instead, you should simply use these directives to label each block of
+your code according to its purpose and let Bison handle the ordering.
+`%code' is the most generic label. Move code to `%code requires',
+`%code provides', or `%code top' as needed.

+3.1.3 The Bison Declarations Section
+------------------------------------
+
+The BISON DECLARATIONS section contains declarations that define
+terminal and nonterminal symbols, specify precedence, and so on. In
+some simple grammars you may not need any declarations. *Note Bison
+Declarations: Declarations.
+
+\1f
+File: bison.info, Node: Grammar Rules, Next: Epilogue, Prev: Bison Declarations, Up: Grammar Outline
+
+3.1.4 The Grammar Rules Section
+-------------------------------
+
+The "grammar rules" section contains one or more Bison grammar rules,
+and nothing else. *Note Syntax of Grammar Rules: Rules.
+
+ There must always be at least one grammar rule, and the first `%%'
+(which precedes the grammar rules) may never be omitted even if it is
+the first thing in the file.
+
+\1f
+File: bison.info, Node: Epilogue, Prev: Grammar Rules, Up: Grammar Outline
+
+3.1.5 The epilogue
+------------------
+
+The EPILOGUE is copied verbatim to the end of the parser implementation
+file, just as the PROLOGUE is copied to the beginning. This is the
+most convenient place to put anything that you want to have in the
+parser implementation file but which need not come before the
+definition of `yyparse'. For example, the definitions of `yylex' and
+`yyerror' often go here. Because C requires functions to be declared
+before being used, you often need to declare functions like `yylex' and
+`yyerror' in the Prologue, even if you define them in the Epilogue.
+*Note Parser C-Language Interface: Interface.
+
+ If the last section is empty, you may omit the `%%' that separates it
+from the grammar rules.
+
+ The Bison parser itself contains many macros and identifiers whose
+names start with `yy' or `YY', so it is a good idea to avoid using any
+such names (except those documented in this manual) in the epilogue of
+the grammar file.
+
+\1f
+File: bison.info, Node: Symbols, Next: Rules, Prev: Grammar Outline, Up: Grammar File
+
+3.2 Symbols, Terminal and Nonterminal
+=====================================
+
+"Symbols" in Bison grammars represent the grammatical classifications
+of the language.
+
+ A "terminal symbol" (also known as a "token type") represents a
+class of syntactically equivalent tokens. You use the symbol in grammar
+rules to mean that a token in that class is allowed. The symbol is
+represented in the Bison parser by a numeric code, and the `yylex'
+function returns a token type code to indicate what kind of token has
+been read. You don't need to know what the code value is; you can use
+the symbol to stand for it.
+
+ A "nonterminal symbol" stands for a class of syntactically
+equivalent groupings. The symbol name is used in writing grammar rules.
+By convention, it should be all lower case.
+
+ Symbol names can contain letters, underscores, periods, and
+non-initial digits and dashes. Dashes in symbol names are a GNU
+extension, incompatible with POSIX Yacc. Periods and dashes make
+symbol names less convenient to use with named references, which
+require brackets around such names (*note Named References::).
+Terminal symbols that contain periods or dashes make little sense:
+since they are not valid symbols (in most programming languages) they
+are not exported as token names.
+
+ There are three ways of writing terminal symbols in the grammar:
+
+ * A "named token type" is written with an identifier, like an
+ identifier in C. By convention, it should be all upper case. Each
+ such name must be defined with a Bison declaration such as
+ `%token'. *Note Token Type Names: Token Decl.
+
+ * A "character token type" (or "literal character token") is written
+ in the grammar using the same syntax used in C for character
+ constants; for example, `'+'' is a character token type. A
+ character token type doesn't need to be declared unless you need to
+ specify its semantic value data type (*note Data Types of Semantic
+ Values: Value Type.), associativity, or precedence (*note Operator
+ Precedence: Precedence.).
+
+ By convention, a character token type is used only to represent a
+ token that consists of that particular character. Thus, the token
+ type `'+'' is used to represent the character `+' as a token.
+ Nothing enforces this convention, but if you depart from it, your
+ program will confuse other readers.
+
+ All the usual escape sequences used in character literals in C can
+ be used in Bison as well, but you must not use the null character
+ as a character literal because its numeric code, zero, signifies
+ end-of-input (*note Calling Convention for `yylex': Calling
+ Convention.). Also, unlike standard C, trigraphs have no special
+ meaning in Bison character literals, nor is backslash-newline
+ allowed.
+
+ * A "literal string token" is written like a C string constant; for
+ example, `"<="' is a literal string token. A literal string token
+ doesn't need to be declared unless you need to specify its semantic
+ value data type (*note Value Type::), associativity, or precedence
+ (*note Precedence::).
+
+ You can associate the literal string token with a symbolic name as
+ an alias, using the `%token' declaration (*note Token
+ Declarations: Token Decl.). If you don't do that, the lexical
+ analyzer has to retrieve the token number for the literal string
+ token from the `yytname' table (*note Calling Convention::).
+
+ *Warning*: literal string tokens do not work in Yacc.
+
+ By convention, a literal string token is used only to represent a
+ token that consists of that particular string. Thus, you should
+ use the token type `"<="' to represent the string `<=' as a token.
+ Bison does not enforce this convention, but if you depart from it,
+ people who read your program will be confused.
+
+ All the escape sequences used in string literals in C can be used
+ in Bison as well, except that you must not use a null character
+ within a string literal. Also, unlike Standard C, trigraphs have
+ no special meaning in Bison string literals, nor is
+ backslash-newline allowed. A literal string token must contain
+ two or more characters; for a token containing just one character,
+ use a character token (see above).
+
+ How you choose to write a terminal symbol has no effect on its
+grammatical meaning. That depends only on where it appears in rules and
+on when the parser function returns that symbol.
+
+ The value returned by `yylex' is always one of the terminal symbols,
+except that a zero or negative value signifies end-of-input. Whichever
+way you write the token type in the grammar rules, you write it the
+same way in the definition of `yylex'. The numeric code for a
+character token type is simply the positive numeric code of the
+character, so `yylex' can use the identical value to generate the
+requisite code, though you may need to convert it to `unsigned char' to
+avoid sign-extension on hosts where `char' is signed. Each named token
+type becomes a C macro in the parser implementation file, so `yylex'
+can use the name to stand for the code. (This is why periods don't
+make sense in terminal symbols.) *Note Calling Convention for `yylex':
+Calling Convention.
+
+ If `yylex' is defined in a separate file, you need to arrange for the
+token-type macro definitions to be available there. Use the `-d'
+option when you run Bison, so that it will write these macro definitions
+into a separate header file `NAME.tab.h' which you can include in the
+other source files that need it. *Note Invoking Bison: Invocation.
+
+ If you want to write a grammar that is portable to any Standard C
+host, you must use only nonnull character tokens taken from the basic
+execution character set of Standard C. This set consists of the ten
+digits, the 52 lower- and upper-case English letters, and the
+characters in the following C-language string:
+
+ "\a\b\t\n\v\f\r !\"#%&'()*+,-./:;<=>?[\\]^_{|}~"
+
+ The `yylex' function and Bison must use a consistent character set
+and encoding for character tokens. For example, if you run Bison in an
+ASCII environment, but then compile and run the resulting program in an
+environment that uses an incompatible character set like EBCDIC, the
+resulting program may not work because the tables generated by Bison
+will assume ASCII numeric values for character tokens. It is standard
+practice for software distributions to contain C source files that were
+generated by Bison in an ASCII environment, so installers on platforms
+that are incompatible with ASCII must rebuild those files before
+compiling them.
+
+ The symbol `error' is a terminal symbol reserved for error recovery
+(*note Error Recovery::); you shouldn't use it for any other purpose.
+In particular, `yylex' should never return this value. The default
+value of the error token is 256, unless you explicitly assigned 256 to
+one of your tokens with a `%token' declaration.
+

+
+3.3 Syntax of Grammar Rules
+===========================
+
+A Bison grammar rule has the following general form:
+
+ RESULT: COMPONENTS...;
+
+where RESULT is the nonterminal symbol that this rule describes, and
+COMPONENTS are various terminal and nonterminal symbols that are put
+together by this rule (*note Symbols::).
+
+ For example,
+
+ exp: exp '+' exp;
+
+says that two groupings of type `exp', with a `+' token in between, can
+be combined into a larger grouping of type `exp'.
+
+ White space in rules is significant only to separate symbols. You
+can add extra white space as you wish.
+
+ Scattered among the components can be ACTIONS that determine the
+semantics of the rule. An action looks like this:
+
+ {C STATEMENTS}
+
+This is an example of "braced code", that is, C code surrounded by
+braces, much like a compound statement in C. Braced code can contain
+any sequence of C tokens, so long as its braces are balanced. Bison
+does not check the braced code for correctness directly; it merely
+copies the code to the parser implementation file, where the C compiler
+can check it.
+
+ Within braced code, the balanced-brace count is not affected by
+braces within comments, string literals, or character constants, but it
+is affected by the C digraphs `<%' and `%>' that represent braces. At
+the top level braced code must be terminated by `}' and not by a
+digraph. Bison does not look for trigraphs, so if braced code uses
+trigraphs you should ensure that they do not affect the nesting of
+braces or the boundaries of comments, string literals, or character
+constants.
+
+ Usually there is only one action and it follows the components.
+*Note Actions::.
+
+ Multiple rules for the same RESULT can be written separately or can
+be joined with the vertical-bar character `|' as follows:
+
+ RESULT:
+ RULE1-COMPONENTS...
+ | RULE2-COMPONENTS...
+ ...
+ ;
+
+They are still considered distinct rules even when joined in this way.
+
+ If COMPONENTS in a rule is empty, it means that RESULT can match the
+empty string. For example, here is how to define a comma-separated
+sequence of zero or more `exp' groupings:
+
+ expseq:
+ /* empty */
+ | expseq1
+ ;
+
+ expseq1:
+ exp
+ | expseq1 ',' exp
+ ;
+
+It is customary to write a comment `/* empty */' in each rule with no
+components.
+
+\1f
+File: bison.info, Node: Recursion, Next: Semantics, Prev: Rules, Up: Grammar File
+
+3.4 Recursive Rules
+===================
+
+A rule is called "recursive" when its RESULT nonterminal appears also
+on its right hand side. Nearly all Bison grammars need to use
+recursion, because that is the only way to define a sequence of any
+number of a particular thing. Consider this recursive definition of a
+comma-separated sequence of one or more expressions:
+
+ expseq1:
+ exp
+ | expseq1 ',' exp
+ ;
+
+Since the recursive use of `expseq1' is the leftmost symbol in the
+right hand side, we call this "left recursion". By contrast, here the
+same construct is defined using "right recursion":
+
+ expseq1:
+ exp
+ | exp ',' expseq1
+ ;
+
+Any kind of sequence can be defined using either left recursion or right
+recursion, but you should always use left recursion, because it can
+parse a sequence of any number of elements with bounded stack space.
+Right recursion uses up space on the Bison stack in proportion to the
+number of elements in the sequence, because all the elements must be
+shifted onto the stack before the rule can be applied even once. *Note
+The Bison Parser Algorithm: Algorithm, for further explanation of this.
+
+ "Indirect" or "mutual" recursion occurs when the result of the rule
+does not appear directly on its right hand side, but does appear in
+rules for other nonterminals which do appear on its right hand side.
+
+ For example:
+
+ expr:
+ primary
+ | primary '+' primary
+ ;
+
+ primary:
+ constant
+ | '(' expr ')'
+ ;
+
+defines two mutually-recursive nonterminals, since each refers to the
+other.

+
+3.5 Defining Language Semantics
+===============================
+
+The grammar rules for a language determine only the syntax. The
+semantics are determined by the semantic values associated with various
+tokens and groupings, and by the actions taken when various groupings
+are recognized.
+
+ For example, the calculator calculates properly because the value
+associated with each expression is the proper number; it adds properly
+because the action for the grouping `X + Y' is to add the numbers
+associated with X and Y.
+
+* Menu:
+
+* Value Type:: Specifying one data type for all semantic values.
+* Multiple Types:: Specifying several alternative data types.
+* Actions:: An action is the semantic definition of a grammar rule.
+* Action Types:: Specifying data types for actions to operate on.
+* Mid-Rule Actions:: Most actions go at the end of a rule.
+ This says when, why and how to use the exceptional
+ action in the middle of a rule.
+
+\1f
+File: bison.info, Node: Value Type, Next: Multiple Types, Up: Semantics
+
+3.5.1 Data Types of Semantic Values
+-----------------------------------
+
+In a simple program it may be sufficient to use the same data type for
+the semantic values of all language constructs. This was true in the
+RPN and infix calculator examples (*note Reverse Polish Notation
+Calculator: RPN Calc.).
+
+ Bison normally uses the type `int' for semantic values if your
+program uses the same data type for all language constructs. To
+specify some other type, define `YYSTYPE' as a macro, like this:
+
+ #define YYSTYPE double
+
+`YYSTYPE''s replacement list should be a type name that does not
+contain parentheses or square brackets. This macro definition must go
+in the prologue of the grammar file (*note Outline of a Bison Grammar:
+Grammar Outline.).
+
+\1f
+File: bison.info, Node: Multiple Types, Next: Actions, Prev: Value Type, Up: Semantics
+
+3.5.2 More Than One Value Type
+------------------------------
+
+In most programs, you will need different data types for different kinds
+of tokens and groupings. For example, a numeric constant may need type
+`int' or `long int', while a string constant needs type `char *', and
+an identifier might need a pointer to an entry in the symbol table.
+
+ To use more than one data type for semantic values in one parser,
+Bison requires you to do two things:
+
+ * Specify the entire collection of possible data types, either by
+ using the `%union' Bison declaration (*note The Collection of
+ Value Types: Union Decl.), or by using a `typedef' or a `#define'
+ to define `YYSTYPE' to be a union type whose member names are the
+ type tags.
+
+ * Choose one of those types for each symbol (terminal or
+ nonterminal) for which semantic values are used. This is done for
+ tokens with the `%token' Bison declaration (*note Token Type
+ Names: Token Decl.) and for groupings with the `%type' Bison
+ declaration (*note Nonterminal Symbols: Type Decl.).
+
+\1f
+File: bison.info, Node: Actions, Next: Action Types, Prev: Multiple Types, Up: Semantics
+
+3.5.3 Actions
+-------------
+
+An action accompanies a syntactic rule and contains C code to be
+executed each time an instance of that rule is recognized. The task of
+most actions is to compute a semantic value for the grouping built by
+the rule from the semantic values associated with tokens or smaller
+groupings.
+
+ An action consists of braced code containing C statements, and can be
+placed at any position in the rule; it is executed at that position.
+Most rules have just one action at the end of the rule, following all
+the components. Actions in the middle of a rule are tricky and used
+only for special purposes (*note Actions in Mid-Rule: Mid-Rule
+Actions.).
+
+ The C code in an action can refer to the semantic values of the
+components matched by the rule with the construct `$N', which stands
+for the value of the Nth component. The semantic value for the
+grouping being constructed is `$$'. In addition, the semantic values
+of symbols can be accessed with the named references construct `$NAME'
+or `$[NAME]'. Bison translates both of these constructs into
+expressions of the appropriate type when it copies the actions into the
+parser implementation file. `$$' (or `$NAME', when it stands for the
+current grouping) is translated to a modifiable lvalue, so it can be
+assigned to.
+
+ Here is a typical example:
+
+ exp:
+ ...
+ | exp '+' exp { $$ = $1 + $3; }
+
+ Or, in terms of named references:
+
+ exp[result]:
+ ...
+ | exp[left] '+' exp[right] { $result = $left + $right; }
+
+This rule constructs an `exp' from two smaller `exp' groupings
+connected by a plus-sign token. In the action, `$1' and `$3' (`$left'
+and `$right') refer to the semantic values of the two component `exp'
+groupings, which are the first and third symbols on the right hand side
+of the rule. The sum is stored into `$$' (`$result') so that it
+becomes the semantic value of the addition-expression just recognized
+by the rule. If there were a useful semantic value associated with the
+`+' token, it could be referred to as `$2'.
+
+ *Note Named References::, for more information about using the named
+references construct.
+
+ Note that the vertical-bar character `|' is really a rule separator,
+and actions are attached to a single rule. This is a difference with
+tools like Flex, for which `|' stands for either "or", or "the same
+action as that of the next rule". In the following example, the action
+is triggered only when `b' is found:
+
+ a-or-b: 'a'|'b' { a_or_b_found = 1; };
+
+ If you don't specify an action for a rule, Bison supplies a default:
+`$$ = $1'. Thus, the value of the first symbol in the rule becomes the
+value of the whole rule. Of course, the default action is valid only
+if the two data types match. There is no meaningful default action for
+an empty rule; every empty rule must have an explicit action unless the
+rule's value does not matter.
+
+ `$N' with N zero or negative is allowed for reference to tokens and
+groupings on the stack _before_ those that match the current rule.
+This is a very risky practice, and to use it reliably you must be
+certain of the context in which the rule is applied. Here is a case in
+which you can use this reliably:
+
+ foo:
+ expr bar '+' expr { ... }
+ | expr bar '-' expr { ... }
+ ;
+
+ bar:
+ /* empty */ { previous_expr = $0; }
+ ;
+
+ As long as `bar' is used only in the fashion shown here, `$0' always
+refers to the `expr' which precedes `bar' in the definition of `foo'.
+
+ It is also possible to access the semantic value of the lookahead
+token, if any, from a semantic action. This semantic value is stored
+in `yylval'. *Note Special Features for Use in Actions: Action
+Features.

+
+3.5.4 Data Types of Values in Actions
+-------------------------------------
+
+If you have chosen a single data type for semantic values, the `$$' and
+`$N' constructs always have that data type.
+
+ If you have used `%union' to specify a variety of data types, then
+you must declare a choice among these types for each terminal or
+nonterminal symbol that can have a semantic value. Then each time you
+use `$$' or `$N', its data type is determined by which symbol it refers
+to in the rule. In this example,
+
+ exp:
+ ...
+ | exp '+' exp { $$ = $1 + $3; }
+
+`$1' and `$3' refer to instances of `exp', so they all have the data
+type declared for the nonterminal symbol `exp'. If `$2' were used, it
+would have the data type declared for the terminal symbol `'+'',
+whatever that might be.
+
+ Alternatively, you can specify the data type when you refer to the
+value, by inserting `<TYPE>' after the `$' at the beginning of the
+reference. For example, if you have defined types as shown here:
+
+ %union {
+ int itype;
+ double dtype;
+ }
+
+then you can write `$<itype>1' to refer to the first subunit of the
+rule as an integer, or `$<dtype>1' to refer to it as a double.
+
+\1f
+File: bison.info, Node: Mid-Rule Actions, Prev: Action Types, Up: Semantics
+
+3.5.5 Actions in Mid-Rule
+-------------------------
+
+Occasionally it is useful to put an action in the middle of a rule.
+These actions are written just like usual end-of-rule actions, but they
+are executed before the parser even recognizes the following components.
+
+ A mid-rule action may refer to the components preceding it using
+`$N', but it may not refer to subsequent components because it is run
+before they are parsed.
+
+ The mid-rule action itself counts as one of the components of the
+rule. This makes a difference when there is another action later in
+the same rule (and usually there is another at the end): you have to
+count the actions along with the symbols when working out which number
+N to use in `$N'.
+
+ The mid-rule action can also have a semantic value. The action can
+set its value with an assignment to `$$', and actions later in the rule
+can refer to the value using `$N'. Since there is no symbol to name
+the action, there is no way to declare a data type for the value in
+advance, so you must use the `$<...>N' construct to specify a data type
+each time you refer to this value.
+
+ There is no way to set the value of the entire rule with a mid-rule
+action, because assignments to `$$' do not have that effect. The only
+way to set the value for the entire rule is with an ordinary action at
+the end of the rule.
+
+ Here is an example from a hypothetical compiler, handling a `let'
+statement that looks like `let (VARIABLE) STATEMENT' and serves to
+create a variable named VARIABLE temporarily for the duration of
+STATEMENT. To parse this construct, we must put VARIABLE into the
+symbol table while STATEMENT is parsed, then remove it afterward. Here
+is how it is done:
+
+ stmt:
+ LET '(' var ')'
+ { $<context>$ = push_context (); declare_variable ($3); }
+ stmt
+ { $$ = $6; pop_context ($<context>5); }
+
+As soon as `let (VARIABLE)' has been recognized, the first action is
+run. It saves a copy of the current semantic context (the list of
+accessible variables) as its semantic value, using alternative
+`context' in the data-type union. Then it calls `declare_variable' to
+add the new variable to that list. Once the first action is finished,
+the embedded statement `stmt' can be parsed. Note that the mid-rule
+action is component number 5, so the `stmt' is component number 6.
+
+ After the embedded statement is parsed, its semantic value becomes
+the value of the entire `let'-statement. Then the semantic value from
+the earlier action is used to restore the prior list of variables. This
+removes the temporary `let'-variable from the list so that it won't
+appear to exist while the rest of the program is parsed.
+
+ In the above example, if the parser initiates error recovery (*note
+Error Recovery::) while parsing the tokens in the embedded statement
+`stmt', it might discard the previous semantic context `$<context>5'
+without restoring it. Thus, `$<context>5' needs a destructor (*note
+Freeing Discarded Symbols: Destructor Decl.). However, Bison currently
+provides no means to declare a destructor specific to a particular
+mid-rule action's semantic value.
+
+ One solution is to bury the mid-rule action inside a nonterminal
+symbol and to declare a destructor for that symbol:
+
+ %type <context> let
+ %destructor { pop_context ($$); } let
+
+ %%
+
+ stmt:
+ let stmt
+ {
+ $$ = $2;
+ pop_context ($1);
+ };
+
+ let:
+ LET '(' var ')'
+ {
+ $$ = push_context ();
+ declare_variable ($3);
+ };
+
+Note that the action is now at the end of its rule. Any mid-rule
+action can be converted to an end-of-rule action in this way, and this
+is what Bison actually does to implement mid-rule actions.
+
+ Taking action before a rule is completely recognized often leads to
+conflicts since the parser must commit to a parse in order to execute
+the action. For example, the following two rules, without mid-rule
+actions, can coexist in a working parser because the parser can shift
+the open-brace token and look at what follows before deciding whether
+there is a declaration or not:
+
+ compound:
+ '{' declarations statements '}'
+ | '{' statements '}'
+ ;
+
+But when we add a mid-rule action as follows, the rules become
+nonfunctional:
+
+ compound:
+ { prepare_for_local_variables (); }
+ '{' declarations statements '}'
+ | '{' statements '}'
+ ;
+
+Now the parser is forced to decide whether to run the mid-rule action
+when it has read no farther than the open-brace. In other words, it
+must commit to using one rule or the other, without sufficient
+information to do it correctly. (The open-brace token is what is called
+the "lookahead" token at this time, since the parser is still deciding
+what to do about it. *Note Lookahead Tokens: Lookahead.)
+
+ You might think that you could correct the problem by putting
+identical actions into the two rules, like this:
+
+ compound:
+ { prepare_for_local_variables (); }
+ '{' declarations statements '}'
+ | { prepare_for_local_variables (); }
+ '{' statements '}'
+ ;
+
+But this does not help, because Bison does not realize that the two
+actions are identical. (Bison never tries to understand the C code in
+an action.)
+
+ If the grammar is such that a declaration can be distinguished from a
+statement by the first token (which is true in C), then one solution
+which does work is to put the action after the open-brace, like this:
+
+ compound:
+ '{' { prepare_for_local_variables (); }
+ declarations statements '}'
+ | '{' statements '}'
+ ;
+
+Now the first token of the following declaration or statement, which
+would in any case tell Bison which rule to use, can still do so.
+
+ Another solution is to bury the action inside a nonterminal symbol
+which serves as a subroutine:
+
+ subroutine:
+ /* empty */ { prepare_for_local_variables (); }
+ ;
+
+ compound:
+ subroutine '{' declarations statements '}'
+ | subroutine '{' statements '}'
+ ;
+
+Now Bison can execute the action in the rule for `subroutine' without
+deciding which rule for `compound' it will eventually use.

+3.6 Tracking Locations
+======================
+
+Though grammar rules and semantic actions are enough to write a fully
+functional parser, it can be useful to process some additional
+information, especially symbol locations.
+
+ The way locations are handled is defined by providing a data type,
+and actions to take when rules are matched.
+
+* Menu:
+
+* Location Type:: Specifying a data type for locations.
+* Actions and Locations:: Using locations in actions.
+* Location Default Action:: Defining a general way to compute locations.
+
+\1f
+File: bison.info, Node: Location Type, Next: Actions and Locations, Up: Tracking Locations
+
+3.6.1 Data Type of Locations
+----------------------------
+
+Defining a data type for locations is much simpler than for semantic
+values, since all tokens and groupings always use the same type.
+
+ You can specify the type of locations by defining a macro called
+`YYLTYPE', just as you can specify the semantic value type by defining
+a `YYSTYPE' macro (*note Value Type::). When `YYLTYPE' is not defined,
+Bison uses a default structure type with four members:
+
+ typedef struct YYLTYPE
+ {
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+ } YYLTYPE;
+
+ When `YYLTYPE' is not defined, at the beginning of the parsing, Bison
+initializes all these fields to 1 for `yylloc'. To initialize `yylloc'
+with a custom location type (or to chose a different initialization),
+use the `%initial-action' directive. *Note Performing Actions before
+Parsing: Initial Action Decl.
+
+\1f
+File: bison.info, Node: Actions and Locations, Next: Location Default Action, Prev: Location Type, Up: Tracking Locations
+
+3.6.2 Actions and Locations
+---------------------------
+
+Actions are not only useful for defining language semantics, but also
+for describing the behavior of the output parser with locations.
+
+ The most obvious way for building locations of syntactic groupings
+is very similar to the way semantic values are computed. In a given
+rule, several constructs can be used to access the locations of the
+elements being matched. The location of the Nth component of the right
+hand side is `@N', while the location of the left hand side grouping is
+`@$'.
+
+ In addition, the named references construct `@NAME' and `@[NAME]'
+may also be used to address the symbol locations. *Note Named
+References::, for more information about using the named references
+construct.
+
+ Here is a basic example using the default data type for locations:
+
+ exp:
+ ...
+ | exp '/' exp
+ {
+ @$.first_column = @1.first_column;
+ @$.first_line = @1.first_line;
+ @$.last_column = @3.last_column;
+ @$.last_line = @3.last_line;
+ if ($3)
+ $$ = $1 / $3;
+ else
+ {
+ $$ = 1;
+ fprintf (stderr,
+ "Division by zero, l%d,c%d-l%d,c%d",
+ @3.first_line, @3.first_column,
+ @3.last_line, @3.last_column);
+ }
+ }
+
+ As for semantic values, there is a default action for locations that
+is run each time a rule is matched. It sets the beginning of `@$' to
+the beginning of the first symbol, and the end of `@$' to the end of the
+last symbol.
+
+ With this default action, the location tracking can be fully
+automatic. The example above simply rewrites this way:
+
+ exp:
+ ...
+ | exp '/' exp
+ {
+ if ($3)
+ $$ = $1 / $3;
+ else
+ {
+ $$ = 1;
+ fprintf (stderr,
+ "Division by zero, l%d,c%d-l%d,c%d",
+ @3.first_line, @3.first_column,
+ @3.last_line, @3.last_column);
+ }
+ }
+
+ It is also possible to access the location of the lookahead token,
+if any, from a semantic action. This location is stored in `yylloc'.
+*Note Special Features for Use in Actions: Action Features.
+
+\1f
+File: bison.info, Node: Location Default Action, Prev: Actions and Locations, Up: Tracking Locations
+
+3.6.3 Default Action for Locations
+----------------------------------
+
+Actually, actions are not the best place to compute locations. Since
+locations are much more general than semantic values, there is room in
+the output parser to redefine the default action to take for each rule.
+The `YYLLOC_DEFAULT' macro is invoked each time a rule is matched,
+before the associated action is run. It is also invoked while
+processing a syntax error, to compute the error's location. Before
+reporting an unresolvable syntactic ambiguity, a GLR parser invokes
+`YYLLOC_DEFAULT' recursively to compute the location of that ambiguity.
+
+ Most of the time, this macro is general enough to suppress location
+dedicated code from semantic actions.
+
+ The `YYLLOC_DEFAULT' macro takes three parameters. The first one is
+the location of the grouping (the result of the computation). When a
+rule is matched, the second parameter identifies locations of all right
+hand side elements of the rule being matched, and the third parameter
+is the size of the rule's right hand side. When a GLR parser reports
+an ambiguity, which of multiple candidate right hand sides it passes to
+`YYLLOC_DEFAULT' is undefined. When processing a syntax error, the
+second parameter identifies locations of the symbols that were
+discarded during error processing, and the third parameter is the
+number of discarded symbols.
+
+ By default, `YYLLOC_DEFAULT' is defined this way:
+
+ # define YYLLOC_DEFAULT(Cur, Rhs, N) \
+ do \
+ if (N) \
+ { \
+ (Cur).first_line = YYRHSLOC(Rhs, 1).first_line; \
+ (Cur).first_column = YYRHSLOC(Rhs, 1).first_column; \
+ (Cur).last_line = YYRHSLOC(Rhs, N).last_line; \
+ (Cur).last_column = YYRHSLOC(Rhs, N).last_column; \
+ } \
+ else \
+ { \
+ (Cur).first_line = (Cur).last_line = \
+ YYRHSLOC(Rhs, 0).last_line; \
+ (Cur).first_column = (Cur).last_column = \
+ YYRHSLOC(Rhs, 0).last_column; \
+ } \
+ while (0)
+
+where `YYRHSLOC (rhs, k)' is the location of the Kth symbol in RHS when
+K is positive, and the location of the symbol just before the reduction
+when K and N are both zero.
+
+ When defining `YYLLOC_DEFAULT', you should consider that:
+
+ * All arguments are free of side-effects. However, only the first
+ one (the result) should be modified by `YYLLOC_DEFAULT'.
+
+ * For consistency with semantic actions, valid indexes within the
+ right hand side range from 1 to N. When N is zero, only 0 is a
+ valid index, and it refers to the symbol just before the reduction.
+ During error processing N is always positive.
+
+ * Your macro should parenthesize its arguments, if need be, since the
+ actual arguments may not be surrounded by parentheses. Also, your
+ macro should expand to something that can be used as a single
+ statement when it is followed by a semicolon.
+

+
+3.7 Named References
+====================
+
+As described in the preceding sections, the traditional way to refer to
+any semantic value or location is a "positional reference", which takes
+the form `$N', `$$', `@N', and `@$'. However, such a reference is not
+very descriptive. Moreover, if you later decide to insert or remove
+symbols in the right-hand side of a grammar rule, the need to renumber
+such references can be tedious and error-prone.
+
+ To avoid these issues, you can also refer to a semantic value or
+location using a "named reference". First of all, original symbol
+names may be used as named references. For example:
+
+ invocation: op '(' args ')'
+ { $invocation = new_invocation ($op, $args, @invocation); }
+
+Positional and named references can be mixed arbitrarily. For example:
+
+ invocation: op '(' args ')'
+ { $$ = new_invocation ($op, $args, @$); }
+
+However, sometimes regular symbol names are not sufficient due to
+ambiguities:
+
+ exp: exp '/' exp
+ { $exp = $exp / $exp; } // $exp is ambiguous.
+
+ exp: exp '/' exp
+ { $$ = $1 / $exp; } // One usage is ambiguous.
+
+ exp: exp '/' exp
+ { $$ = $1 / $3; } // No error.
+
+When ambiguity occurs, explicitly declared names may be used for values
+and locations. Explicit names are declared as a bracketed name after a
+symbol appearance in rule definitions. For example:
+ exp[result]: exp[left] '/' exp[right]
+ { $result = $left / $right; }
+
+In order to access a semantic value generated by a mid-rule action, an
+explicit name may also be declared by putting a bracketed name after the
+closing brace of the mid-rule action code:
+ exp[res]: exp[x] '+' {$left = $x;}[left] exp[right]
+ { $res = $left + $right; }
+
+In references, in order to specify names containing dots and dashes, an
+explicit bracketed syntax `$[name]' and `@[name]' must be used:
+ if-stmt: "if" '(' expr ')' "then" then.stmt ';'
+ { $[if-stmt] = new_if_stmt ($expr, $[then.stmt]); }
+
+ It often happens that named references are followed by a dot, dash
+or other C punctuation marks and operators. By default, Bison will read
+`$name.suffix' as a reference to symbol value `$name' followed by
+`.suffix', i.e., an access to the `suffix' field of the semantic value.
+In order to force Bison to recognize `name.suffix' in its entirety as
+the name of a semantic value, the bracketed syntax `$[name.suffix]'
+must be used.
+
+ The named references feature is experimental. More user feedback
+will help to stabilize it.

+3.8 Bison Declarations
+======================
+
+The "Bison declarations" section of a Bison grammar defines the symbols
+used in formulating the grammar and the data types of semantic values.
+*Note Symbols::.
+
+ All token type names (but not single-character literal tokens such as
+`'+'' and `'*'') must be declared. Nonterminal symbols must be
+declared if you need to specify which data type to use for the semantic
+value (*note More Than One Value Type: Multiple Types.).
+
+ The first rule in the grammar file also specifies the start symbol,
+by default. If you want some other symbol to be the start symbol, you
+must declare it explicitly (*note Languages and Context-Free Grammars:
+Language and Grammar.).
+
+* Menu:
+
+* Require Decl:: Requiring a Bison version.
+* Token Decl:: Declaring terminal symbols.
+* Precedence Decl:: Declaring terminals with precedence and associativity.
+* Union Decl:: Declaring the set of all semantic value types.
+* Type Decl:: Declaring the choice of type for a nonterminal symbol.
+* Initial Action Decl:: Code run before parsing starts.
+* Destructor Decl:: Declaring how symbols are freed.
+* Printer Decl:: Declaring how symbol values are displayed.
+* Expect Decl:: Suppressing warnings about parsing conflicts.

+* %code Summary:: Inserting code into the parser source.
+
+\1f
+File: bison.info, Node: Require Decl, Next: Token Decl, Up: Declarations
+
+3.8.1 Require a Version of Bison
+--------------------------------
+
+You may require the minimum version of Bison to process the grammar. If
+the requirement is not met, `bison' exits with an error (exit status
+63).
+
+ %require "VERSION"
+
+\1f
+File: bison.info, Node: Token Decl, Next: Precedence Decl, Prev: Require Decl, Up: Declarations
+
+3.8.2 Token Type Names
+----------------------
+
+The basic way to declare a token type name (terminal symbol) is as
+follows:
+
+ %token NAME
+
+ Bison will convert this into a `#define' directive in the parser, so
+that the function `yylex' (if it is in this file) can use the name NAME
+to stand for this token type's code.
+
+ Alternatively, you can use `%left', `%right', or `%nonassoc' instead
+of `%token', if you wish to specify associativity and precedence.
+*Note Operator Precedence: Precedence Decl.
+
+ You can explicitly specify the numeric code for a token type by
+appending a nonnegative decimal or hexadecimal integer value in the
+field immediately following the token name:
+
+ %token NUM 300
+ %token XNUM 0x12d // a GNU extension
+
+It is generally best, however, to let Bison choose the numeric codes for
+all token types. Bison will automatically select codes that don't
+conflict with each other or with normal characters.
+
+ In the event that the stack type is a union, you must augment the
+`%token' or other token declaration to include the data type
+alternative delimited by angle-brackets (*note More Than One Value
+Type: Multiple Types.).
+
+ For example:
+
+ %union { /* define stack type */
+ double val;
+ symrec *tptr;
+ }
+ %token <val> NUM /* define token NUM and its type */
+
+ You can associate a literal string token with a token type name by
+writing the literal string at the end of a `%token' declaration which
+declares the name. For example:
+
+ %token arrow "=>"
+
+For example, a grammar for the C language might specify these names with
+equivalent literal string tokens:
+
+ %token <operator> OR "||"
+ %token <operator> LE 134 "<="
+ %left OR "<="
+
+Once you equate the literal string and the token name, you can use them
+interchangeably in further declarations or the grammar rules. The
+`yylex' function can use the token name or the literal string to obtain
+the token type code number (*note Calling Convention::). Syntax error
+messages passed to `yyerror' from the parser will reference the literal
+string instead of the token name.
+
+ The token numbered as 0 corresponds to end of file; the following
+line allows for nicer error messages referring to "end of file" instead
+of "$end":
+
+ %token END 0 "end of file"
+
+\1f
+File: bison.info, Node: Precedence Decl, Next: Union Decl, Prev: Token Decl, Up: Declarations
+
+3.8.3 Operator Precedence
+-------------------------
+
+Use the `%left', `%right' or `%nonassoc' declaration to declare a token
+and specify its precedence and associativity, all at once. These are
+called "precedence declarations". *Note Operator Precedence:
+Precedence, for general information on operator precedence.
+
+ The syntax of a precedence declaration is nearly the same as that of
+`%token': either
+
+ %left SYMBOLS...
+
+or
+
+ %left <TYPE> SYMBOLS...
+
+ And indeed any of these declarations serves the purposes of `%token'.
+But in addition, they specify the associativity and relative precedence
+for all the SYMBOLS:
+
+ * The associativity of an operator OP determines how repeated uses
+ of the operator nest: whether `X OP Y OP Z' is parsed by grouping
+ X with Y first or by grouping Y with Z first. `%left' specifies
+ left-associativity (grouping X with Y first) and `%right'
+ specifies right-associativity (grouping Y with Z first).
+ `%nonassoc' specifies no associativity, which means that `X OP Y
+ OP Z' is considered a syntax error.
+
+ * The precedence of an operator determines how it nests with other
+ operators. All the tokens declared in a single precedence
+ declaration have equal precedence and nest together according to
+ their associativity. When two tokens declared in different
+ precedence declarations associate, the one declared later has the
+ higher precedence and is grouped first.
+
+ For backward compatibility, there is a confusing difference between
+the argument lists of `%token' and precedence declarations. Only a
+`%token' can associate a literal string with a token type name. A
+precedence declaration always interprets a literal string as a
+reference to a separate token. For example:
+
+ %left OR "<=" // Does not declare an alias.
+ %left OR 134 "<=" 135 // Declares 134 for OR and 135 for "<=".
+
+\1f
+File: bison.info, Node: Union Decl, Next: Type Decl, Prev: Precedence Decl, Up: Declarations
+
+3.8.4 The Collection of Value Types
+-----------------------------------
+
+The `%union' declaration specifies the entire collection of possible
+data types for semantic values. The keyword `%union' is followed by
+braced code containing the same thing that goes inside a `union' in C.
+
+ For example:
+
+ %union {
+ double val;
+ symrec *tptr;
+ }
+
+This says that the two alternative types are `double' and `symrec *'.
+They are given names `val' and `tptr'; these names are used in the
+`%token' and `%type' declarations to pick one of the types for a
+terminal or nonterminal symbol (*note Nonterminal Symbols: Type Decl.).
+
+ As an extension to POSIX, a tag is allowed after the `union'. For
+example:
+
+ %union value {
+ double val;
+ symrec *tptr;
+ }
+
+specifies the union tag `value', so the corresponding C type is `union
+value'. If you do not specify a tag, it defaults to `YYSTYPE'.
+
+ As another extension to POSIX, you may specify multiple `%union'
+declarations; their contents are concatenated. However, only the first
+`%union' declaration can specify a tag.
+
+ Note that, unlike making a `union' declaration in C, you need not
+write a semicolon after the closing brace.
+
+ Instead of `%union', you can define and use your own union type
+`YYSTYPE' if your grammar contains at least one `<TYPE>' tag. For
+example, you can put the following into a header file `parser.h':
+
+ union YYSTYPE {
+ double val;
+ symrec *tptr;
+ };
+ typedef union YYSTYPE YYSTYPE;
+
+and then your grammar can use the following instead of `%union':
+
+ %{
+ #include "parser.h"
+ %}
+ %type <val> expr
+ %token <tptr> ID

+
+3.8.5 Nonterminal Symbols
+-------------------------
+
+When you use `%union' to specify multiple value types, you must declare
+the value type of each nonterminal symbol for which values are used.
+This is done with a `%type' declaration, like this:
+
+ %type <TYPE> NONTERMINAL...
+
+Here NONTERMINAL is the name of a nonterminal symbol, and TYPE is the
+name given in the `%union' to the alternative that you want (*note The
+Collection of Value Types: Union Decl.). You can give any number of
+nonterminal symbols in the same `%type' declaration, if they have the
+same value type. Use spaces to separate the symbol names.
+
+ You can also declare the value type of a terminal symbol. To do
+this, use the same `<TYPE>' construction in a declaration for the
+terminal symbol. All kinds of token declarations allow `<TYPE>'.

+
+3.8.6 Performing Actions before Parsing
+---------------------------------------
+
+Sometimes your parser needs to perform some initializations before
+parsing. The `%initial-action' directive allows for such arbitrary
+code.
+
+ -- Directive: %initial-action { CODE }
+ Declare that the braced CODE must be invoked before parsing each
+ time `yyparse' is called. The CODE may use `$$' and `@$' --
+ initial value and location of the lookahead -- and the
+ `%parse-param'.
+
+ For instance, if your locations use a file name, you may use
+
+ %parse-param { char const *file_name };
+ %initial-action
+ {
+ @$.initialize (file_name);
+ };
+
+\1f
+File: bison.info, Node: Destructor Decl, Next: Printer Decl, Prev: Initial Action Decl, Up: Declarations
+
+3.8.7 Freeing Discarded Symbols
+-------------------------------
+
+During error recovery (*note Error Recovery::), symbols already pushed
+on the stack and tokens coming from the rest of the file are discarded
+until the parser falls on its feet. If the parser runs out of memory,
+or if it returns via `YYABORT' or `YYACCEPT', all the symbols on the
+stack must be discarded. Even if the parser succeeds, it must discard
+the start symbol.
+
+ When discarded symbols convey heap based information, this memory is
+lost. While this behavior can be tolerable for batch parsers, such as
+in traditional compilers, it is unacceptable for programs like shells or
+protocol implementations that may parse and execute indefinitely.
+
+ The `%destructor' directive defines code that is called when a
+symbol is automatically discarded.
+
+ -- Directive: %destructor { CODE } SYMBOLS
+ Invoke the braced CODE whenever the parser discards one of the
+ SYMBOLS. Within CODE, `$$' designates the semantic value
+ associated with the discarded symbol, and `@$' designates its
+ location. The additional parser parameters are also available
+ (*note The Parser Function `yyparse': Parser Function.).
+
+ When a symbol is listed among SYMBOLS, its `%destructor' is called
+ a per-symbol `%destructor'. You may also define a per-type
+ `%destructor' by listing a semantic type tag among SYMBOLS. In
+ that case, the parser will invoke this CODE whenever it discards
+ any grammar symbol that has that semantic type tag unless that
+ symbol has its own per-symbol `%destructor'.
+
+ Finally, you can define two different kinds of default
+ `%destructor's. (These default forms are experimental. More user
+ feedback will help to determine whether they should become
+ permanent features.) You can place each of `<*>' and `<>' in the
+ SYMBOLS list of exactly one `%destructor' declaration in your
+ grammar file. The parser will invoke the CODE associated with one
+ of these whenever it discards any user-defined grammar symbol that
+ has no per-symbol and no per-type `%destructor'. The parser uses
+ the CODE for `<*>' in the case of such a grammar symbol for which
+ you have formally declared a semantic type tag (`%type' counts as
+ such a declaration, but `$<tag>$' does not). The parser uses the
+ CODE for `<>' in the case of such a grammar symbol that has no
+ declared semantic type tag.
+
+For example:
+
+ %union { char *string; }
+ %token <string> STRING1
+ %token <string> STRING2
+ %type <string> string1
+ %type <string> string2
+ %union { char character; }
+ %token <character> CHR
+ %type <character> chr
+ %token TAGLESS
+
+ %destructor { } <character>
+ %destructor { free ($$); } <*>
+ %destructor { free ($$); printf ("%d", @$.first_line); } STRING1 string1
+ %destructor { printf ("Discarding tagless symbol.\n"); } <>
+
+guarantees that, when the parser discards any user-defined symbol that
+has a semantic type tag other than `<character>', it passes its
+semantic value to `free' by default. However, when the parser discards
+a `STRING1' or a `string1', it also prints its line number to `stdout'.
+It performs only the second `%destructor' in this case, so it invokes
+`free' only once. Finally, the parser merely prints a message whenever
+it discards any symbol, such as `TAGLESS', that has no semantic type
+tag.
+
+ A Bison-generated parser invokes the default `%destructor's only for
+user-defined as opposed to Bison-defined symbols. For example, the
+parser will not invoke either kind of default `%destructor' for the
+special Bison-defined symbols `$accept', `$undefined', or `$end' (*note
+Bison Symbols: Table of Symbols.), none of which you can reference in
+your grammar. It also will not invoke either for the `error' token
+(*note error: Table of Symbols.), which is always defined by Bison
+regardless of whether you reference it in your grammar. However, it
+may invoke one of them for the end token (token 0) if you redefine it
+from `$end' to, for example, `END':
+
+ %token END 0
+
+ Finally, Bison will never invoke a `%destructor' for an unreferenced
+mid-rule semantic value (*note Actions in Mid-Rule: Mid-Rule Actions.).
+That is, Bison does not consider a mid-rule to have a semantic value if
+you do not reference `$$' in the mid-rule's action or `$N' (where N is
+the right-hand side symbol position of the mid-rule) in any later
+action in that rule. However, if you do reference either, the
+Bison-generated parser will invoke the `<>' `%destructor' whenever it
+discards the mid-rule symbol.
+
+
+ "Discarded symbols" are the following:
+
+ * stacked symbols popped during the first phase of error recovery,
+
+ * incoming terminals during the second phase of error recovery,
+
+ * the current lookahead and the entire stack (except the current
+ right-hand side symbols) when the parser returns immediately, and
+
+ * the start symbol, when the parser succeeds.
+
+ The parser can "return immediately" because of an explicit call to
+`YYABORT' or `YYACCEPT', or failed error recovery, or memory exhaustion.
+
+ Right-hand side symbols of a rule that explicitly triggers a syntax
+error via `YYERROR' are not discarded automatically. As a rule of
+thumb, destructors are invoked only when user actions cannot manage the
+memory.
+

+
+3.8.8 Printing Semantic Values
+------------------------------
+
+When run-time traces are enabled (*note Tracing Your Parser: Tracing.),
+the parser reports its actions, such as reductions. When a symbol
+involved in an action is reported, only its kind is displayed, as the
+parser cannot know how semantic values should be formatted.
+
+ The `%printer' directive defines code that is called when a symbol is
+reported. Its syntax is the same as `%destructor' (*note Freeing
+Discarded Symbols: Destructor Decl.).
+
+ -- Directive: %printer { CODE } SYMBOLS
+ Invoke the braced CODE whenever the parser displays one of the
+ SYMBOLS. Within CODE, `yyoutput' denotes the output stream (a
+ `FILE*' in C, and an `std::ostream&' in C++), `$$' designates the
+ semantic value associated with the symbol, and `@$' its location.
+ The additional parser parameters are also available (*note The
+ Parser Function `yyparse': Parser Function.).
+
+ The SYMBOLS are defined as for `%destructor' (*note Freeing
+ Discarded Symbols: Destructor Decl.): they can be per-type (e.g.,
+ `<ival>'), per-symbol (e.g., `exp', `NUM', `"float"'), typed
+ per-default (i.e., `<*>', or untyped per-default (i.e., `<>').
+
+For example:
+
+ %union { char *string; }
+ %token <string> STRING1
+ %token <string> STRING2
+ %type <string> string1
+ %type <string> string2
+ %union { char character; }
+ %token <character> CHR
+ %type <character> chr
+ %token TAGLESS
+
+ %printer { fprintf (yyoutput, "'%c'", $$); } <character>
+ %printer { fprintf (yyoutput, "&%p", $$); } <*>
+ %printer { fprintf (yyoutput, "\"%s\"", $$); } STRING1 string1
+ %printer { fprintf (yyoutput, "<>"); } <>
+
+guarantees that, when the parser print any symbol that has a semantic
+type tag other than `<character>', it display the address of the
+semantic value by default. However, when the parser displays a
+`STRING1' or a `string1', it formats it as a string in double quotes.
+It performs only the second `%printer' in this case, so it prints only
+once. Finally, the parser print `<>' for any symbol, such as `TAGLESS',
+that has no semantic type tag. See also
+

+File: bison.info, Node: Expect Decl, Next: Start Decl, Prev: Printer Decl, Up: Declarations
+
+3.8.9 Suppressing Conflict Warnings
+-----------------------------------
+
+Bison normally warns if there are any conflicts in the grammar (*note
+Shift/Reduce Conflicts: Shift/Reduce.), but most real grammars have
+harmless shift/reduce conflicts which are resolved in a predictable way
+and would be difficult to eliminate. It is desirable to suppress the
+warning about these conflicts unless the number of conflicts changes.
+You can do this with the `%expect' declaration.
+
+ The declaration looks like this:
+
+ %expect N
+
+ Here N is a decimal integer. The declaration says there should be N
+shift/reduce conflicts and no reduce/reduce conflicts. Bison reports
+an error if the number of shift/reduce conflicts differs from N, or if
+there are any reduce/reduce conflicts.
+
+ For deterministic parsers, reduce/reduce conflicts are more serious,
+and should be eliminated entirely. Bison will always report
+reduce/reduce conflicts for these parsers. With GLR parsers, however,
+both kinds of conflicts are routine; otherwise, there would be no need
+to use GLR parsing. Therefore, it is also possible to specify an
+expected number of reduce/reduce conflicts in GLR parsers, using the
+declaration:
+
+ %expect-rr N
+
+ In general, using `%expect' involves these steps:
+
+ * Compile your grammar without `%expect'. Use the `-v' option to
+ get a verbose list of where the conflicts occur. Bison will also
+ print the number of conflicts.
+
+ * Check each of the conflicts to make sure that Bison's default
+ resolution is what you really want. If not, rewrite the grammar
+ and go back to the beginning.
+
+ * Add an `%expect' declaration, copying the number N from the number
+ which Bison printed. With GLR parsers, add an `%expect-rr'
+ declaration as well.
+
+ Now Bison will report an error if you introduce an unexpected
+conflict, but will keep silent otherwise.

+
+3.8.10 The Start-Symbol
+-----------------------
+
+Bison assumes by default that the start symbol for the grammar is the
+first nonterminal specified in the grammar specification section. The
+programmer may override this restriction with the `%start' declaration
+as follows:
+
+ %start SYMBOL
+
+\1f
+File: bison.info, Node: Pure Decl, Next: Push Decl, Prev: Start Decl, Up: Declarations
+
+3.8.11 A Pure (Reentrant) Parser
+--------------------------------
+
+A "reentrant" program is one which does not alter in the course of
+execution; in other words, it consists entirely of "pure" (read-only)
+code. Reentrancy is important whenever asynchronous execution is
+possible; for example, a nonreentrant program may not be safe to call
+from a signal handler. In systems with multiple threads of control, a
+nonreentrant program must be called only within interlocks.
+
+ Normally, Bison generates a parser which is not reentrant. This is
+suitable for most uses, and it permits compatibility with Yacc. (The
+standard Yacc interfaces are inherently nonreentrant, because they use
+statically allocated variables for communication with `yylex',
+including `yylval' and `yylloc'.)
+
+ Alternatively, you can generate a pure, reentrant parser. The Bison
+declaration `%define api.pure' says that you want the parser to be
+reentrant. It looks like this:
+
+ %define api.pure
+
+ The result is that the communication variables `yylval' and `yylloc'
+become local variables in `yyparse', and a different calling convention
+is used for the lexical analyzer function `yylex'. *Note Calling
+Conventions for Pure Parsers: Pure Calling, for the details of this.
+The variable `yynerrs' becomes local in `yyparse' in pull mode but it
+becomes a member of yypstate in push mode. (*note The Error Reporting
+Function `yyerror': Error Reporting.). The convention for calling
+`yyparse' itself is unchanged.
+
+ Whether the parser is pure has nothing to do with the grammar rules.
+You can generate either a pure parser or a nonreentrant parser from any
+valid grammar.
+

+File: bison.info, Node: Push Decl, Next: Decl Summary, Prev: Pure Decl, Up: Declarations
+
+3.8.12 A Push Parser
+--------------------
+
+(The current push parsing interface is experimental and may evolve.
+More user feedback will help to stabilize it.)
+
+ A pull parser is called once and it takes control until all its input
+is completely parsed. A push parser, on the other hand, is called each
+time a new token is made available.
+
+ A push parser is typically useful when the parser is part of a main
+event loop in the client's application. This is typically a
+requirement of a GUI, when the main event loop needs to be triggered
+within a certain time period.
+
+ Normally, Bison generates a pull parser. The following Bison
+declaration says that you want the parser to be a push parser (*note
+api.push-pull: %define Summary.):
+
+ %define api.push-pull push
+
+ In almost all cases, you want to ensure that your push parser is also
+a pure parser (*note A Pure (Reentrant) Parser: Pure Decl.). The only
+time you should create an impure push parser is to have backwards
+compatibility with the impure Yacc pull mode interface. Unless you know
+what you are doing, your declarations should look like this:
+
+ %define api.pure
+ %define api.push-pull push
+
+ There is a major notable functional difference between the pure push
+parser and the impure push parser. It is acceptable for a pure push
+parser to have many parser instances, of the same type of parser, in
+memory at the same time. An impure push parser should only use one
+parser at a time.
+
+ When a push parser is selected, Bison will generate some new symbols
+in the generated parser. `yypstate' is a structure that the generated
+parser uses to store the parser's state. `yypstate_new' is the
+function that will create a new parser instance. `yypstate_delete'
+will free the resources associated with the corresponding parser
+instance. Finally, `yypush_parse' is the function that should be
+called whenever a token is available to provide the parser. A trivial
+example of using a pure push parser would look like this:
+
+ int status;
+ yypstate *ps = yypstate_new ();
+ do {
+ status = yypush_parse (ps, yylex (), NULL);
+ } while (status == YYPUSH_MORE);
+ yypstate_delete (ps);
+
+ If the user decided to use an impure push parser, a few things about
+the generated parser will change. The `yychar' variable becomes a
+global variable instead of a variable in the `yypush_parse' function.
+For this reason, the signature of the `yypush_parse' function is
+changed to remove the token as a parameter. A nonreentrant push parser
+example would thus look like this:
+
+ extern int yychar;
+ int status;
+ yypstate *ps = yypstate_new ();
+ do {
+ yychar = yylex ();
+ status = yypush_parse (ps);
+ } while (status == YYPUSH_MORE);
+ yypstate_delete (ps);
+
+ That's it. Notice the next token is put into the global variable
+`yychar' for use by the next invocation of the `yypush_parse' function.
+
+ Bison also supports both the push parser interface along with the
+pull parser interface in the same generated parser. In order to get
+this functionality, you should replace the `%define api.push-pull push'
+declaration with the `%define api.push-pull both' declaration. Doing
+this will create all of the symbols mentioned earlier along with the
+two extra symbols, `yyparse' and `yypull_parse'. `yyparse' can be used
+exactly as it normally would be used. However, the user should note
+that it is implemented in the generated parser by calling
+`yypull_parse'. This makes the `yyparse' function that is generated
+with the `%define api.push-pull both' declaration slower than the normal
+`yyparse' function. If the user calls the `yypull_parse' function it
+will parse the rest of the input stream. It is possible to
+`yypush_parse' tokens to select a subgrammar and then `yypull_parse'
+the rest of the input stream. If you would like to switch back and
+forth between between parsing styles, you would have to write your own
+`yypull_parse' function that knows when to quit looking for input. An
+example of using the `yypull_parse' function would look like this:
+
+ yypstate *ps = yypstate_new ();
+ yypull_parse (ps); /* Will call the lexer */
+ yypstate_delete (ps);
+
+ Adding the `%define api.pure' declaration does exactly the same
+thing to the generated parser with `%define api.push-pull both' as it
+did for `%define api.push-pull push'.

+3.8.13 Bison Declaration Summary
+--------------------------------
+
+Here is a summary of the declarations used to define a grammar:
+
+ -- Directive: %union
+ Declare the collection of data types that semantic values may have
+ (*note The Collection of Value Types: Union Decl.).
+
+ -- Directive: %token
+ Declare a terminal symbol (token type name) with no precedence or
+ associativity specified (*note Token Type Names: Token Decl.).
+
+ -- Directive: %right
+ Declare a terminal symbol (token type name) that is
+ right-associative (*note Operator Precedence: Precedence Decl.).
+
+ -- Directive: %left
+ Declare a terminal symbol (token type name) that is
+ left-associative (*note Operator Precedence: Precedence Decl.).
+
+ -- Directive: %nonassoc
+ Declare a terminal symbol (token type name) that is nonassociative
+ (*note Operator Precedence: Precedence Decl.). Using it in a way
+ that would be associative is a syntax error.
+
+ -- Directive: %type
+ Declare the type of semantic values for a nonterminal symbol
+ (*note Nonterminal Symbols: Type Decl.).
+
+ -- Directive: %start
+ Specify the grammar's start symbol (*note The Start-Symbol: Start
+ Decl.).
+
+ -- Directive: %expect
+ Declare the expected number of shift-reduce conflicts (*note
+ Suppressing Conflict Warnings: Expect Decl.).
+
+
+In order to change the behavior of `bison', use the following
+directives:
+
+ -- Directive: %code {CODE}
+ -- Directive: %code QUALIFIER {CODE}
+ Insert CODE verbatim into the output parser source at the default
+ location or at the location specified by QUALIFIER. *Note %code
+ Summary::.
+
+ -- Directive: %debug
+ In the parser implementation file, define the macro `YYDEBUG' (or
+ `PREFIXDEBUG' with `%define api.prefix PREFIX'), see *note
+ Multiple Parsers in the Same Program: Multiple Parsers.) to 1 if
+ it is not already defined, so that the debugging facilities are
+ compiled. *Note Tracing Your Parser: Tracing.
+
+ -- Directive: %define VARIABLE
+ -- Directive: %define VARIABLE VALUE
+ -- Directive: %define VARIABLE "VALUE"
+ Define a variable to adjust Bison's behavior. *Note %define
+ Summary::.
+
+ -- Directive: %defines
+ Write a parser header file containing macro definitions for the
+ token type names defined in the grammar as well as a few other
+ declarations. If the parser implementation file is named `NAME.c'
+ then the parser header file is named `NAME.h'.
+
+ For C parsers, the parser header file declares `YYSTYPE' unless
+ `YYSTYPE' is already defined as a macro or you have used a
+ `<TYPE>' tag without using `%union'. Therefore, if you are using
+ a `%union' (*note More Than One Value Type: Multiple Types.) with
+ components that require other definitions, or if you have defined
+ a `YYSTYPE' macro or type definition (*note Data Types of Semantic
+ Values: Value Type.), you need to arrange for these definitions to
+ be propagated to all modules, e.g., by putting them in a
+ prerequisite header that is included both by your parser and by any
+ other module that needs `YYSTYPE'.
+
+ Unless your parser is pure, the parser header file declares
+ `yylval' as an external variable. *Note A Pure (Reentrant)
+ Parser: Pure Decl.
+
+ If you have also used locations, the parser header file declares
+ `YYLTYPE' and `yylloc' using a protocol similar to that of the
+ `YYSTYPE' macro and `yylval'. *Note Tracking Locations::.
+
+ This parser header file is normally essential if you wish to put
+ the definition of `yylex' in a separate source file, because
+ `yylex' typically needs to be able to refer to the above-mentioned
+ declarations and to the token type codes. *Note Semantic Values
+ of Tokens: Token Values.
+
+ If you have declared `%code requires' or `%code provides', the
+ output header also contains their code. *Note %code Summary::.
+
+ -- Directive: %defines DEFINES-FILE
+ Same as above, but save in the file DEFINES-FILE.
+
+ -- Directive: %destructor
+ Specify how the parser should reclaim the memory associated to
+ discarded symbols. *Note Freeing Discarded Symbols: Destructor
+ Decl.
+
+ -- Directive: %file-prefix "PREFIX"
+ Specify a prefix to use for all Bison output file names. The names
+ are chosen as if the grammar file were named `PREFIX.y'.
+
+ -- Directive: %language "LANGUAGE"
+ Specify the programming language for the generated parser.
+ Currently supported languages include C, C++, and Java. LANGUAGE
+ is case-insensitive.
+
+ This directive is experimental and its effect may be modified in
+ future releases.
+
+ -- Directive: %locations
+ Generate the code processing the locations (*note Special Features
+ for Use in Actions: Action Features.). This mode is enabled as
+ soon as the grammar uses the special `@N' tokens, but if your
+ grammar does not use it, using `%locations' allows for more
+ accurate syntax error messages.
+
+ -- Directive: %no-lines
+ Don't generate any `#line' preprocessor commands in the parser
+ implementation file. Ordinarily Bison writes these commands in the
+ parser implementation file so that the C compiler and debuggers
+ will associate errors and object code with your source file (the
+ grammar file). This directive causes them to associate errors
+ with the parser implementation file, treating it as an independent
+ source file in its own right.
+
+ -- Directive: %output "FILE"
+ Specify FILE for the parser implementation file.
+
+ -- Directive: %pure-parser
+ Deprecated version of `%define api.pure' (*note api.pure: %define
+ Summary.), for which Bison is more careful to warn about
+ unreasonable usage.
+
+ -- Directive: %require "VERSION"
+ Require version VERSION or higher of Bison. *Note Require a
+ Version of Bison: Require Decl.
+
+ -- Directive: %skeleton "FILE"
+ Specify the skeleton to use.
+
+ If FILE does not contain a `/', FILE is the name of a skeleton
+ file in the Bison installation directory. If it does, FILE is an
+ absolute file name or a file name relative to the directory of the
+ grammar file. This is similar to how most shells resolve commands.
+
+ -- Directive: %token-table
+ Generate an array of token names in the parser implementation file.
+ The name of the array is `yytname'; `yytname[I]' is the name of
+ the token whose internal Bison token code number is I. The first
+ three elements of `yytname' correspond to the predefined tokens
+ `"$end"', `"error"', and `"$undefined"'; after these come the
+ symbols defined in the grammar file.
+
+ The name in the table includes all the characters needed to
+ represent the token in Bison. For single-character literals and
+ literal strings, this includes the surrounding quoting characters
+ and any escape sequences. For example, the Bison single-character
+ literal `'+'' corresponds to a three-character name, represented
+ in C as `"'+'"'; and the Bison two-character literal string `"\\/"'
+ corresponds to a five-character name, represented in C as
+ `"\"\\\\/\""'.
+
+ When you specify `%token-table', Bison also generates macro
+ definitions for macros `YYNTOKENS', `YYNNTS', and `YYNRULES', and
+ `YYNSTATES':
+
+ `YYNTOKENS'
+ The highest token number, plus one.
+
+ `YYNNTS'
+ The number of nonterminal symbols.
+
+ `YYNRULES'
+ The number of grammar rules,
+
+ `YYNSTATES'
+ The number of parser states (*note Parser States::).
+
+ -- Directive: %verbose
+ Write an extra output file containing verbose descriptions of the
+ parser states and what is done for each type of lookahead token in
+ that state. *Note Understanding Your Parser: Understanding, for
+ more information.
+
+ -- Directive: %yacc
+ Pretend the option `--yacc' was given, i.e., imitate Yacc,
+ including its naming conventions. *Note Bison Options::, for more.

+
+3.8.14 %define Summary
+----------------------
+
+There are many features of Bison's behavior that can be controlled by
+assigning the feature a single value. For historical reasons, some
+such features are assigned values by dedicated directives, such as
+`%start', which assigns the start symbol. However, newer such features
+are associated with variables, which are assigned by the `%define'
+directive:
+
+ -- Directive: %define VARIABLE
+ -- Directive: %define VARIABLE VALUE
+ -- Directive: %define VARIABLE "VALUE"
+ Define VARIABLE to VALUE.
+
+ VALUE must be placed in quotation marks if it contains any
+ character other than a letter, underscore, period, or non-initial
+ dash or digit. Omitting `"VALUE"' entirely is always equivalent
+ to specifying `""'.
+
+ It is an error if a VARIABLE is defined by `%define' multiple
+ times, but see *note -D NAME[=VALUE]: Bison Options.
+
+ The rest of this section summarizes variables and values that
+`%define' accepts.
+
+ Some VARIABLEs take Boolean values. In this case, Bison will
+complain if the variable definition does not meet one of the following
+four conditions:
+
+ 1. `VALUE' is `true'
+
+ 2. `VALUE' is omitted (or `""' is specified). This is equivalent to
+ `true'.
+
+ 3. `VALUE' is `false'.
+
+ 4. VARIABLE is never defined. In this case, Bison selects a default
+ value.
+
+ What VARIABLEs are accepted, as well as their meanings and default
+values, depend on the selected target language and/or the parser
+skeleton (*note %language: Decl Summary, *note %skeleton: Decl
+Summary.). Unaccepted VARIABLEs produce an error. Some of the
+accepted VARIABLEs are:
+
+ * `api.prefix'
+

+3.8.15 %code Summary
+--------------------
+
+The `%code' directive inserts code verbatim into the output parser
+source at any of a predefined set of locations. It thus serves as a
+flexible and user-friendly alternative to the traditional Yacc
+prologue, `%{CODE%}'. This section summarizes the functionality of
+`%code' for the various target languages supported by Bison. For a
+detailed discussion of how to use `%code' in place of `%{CODE%}' for
+C/C++ and why it is advantageous to do so, *note Prologue
+Alternatives::.
+
+ -- Directive: %code {CODE}
+ This is the unqualified form of the `%code' directive. It inserts
+ CODE verbatim at a language-dependent default location in the
+ parser implementation.
+
+ For C/C++, the default location is the parser implementation file
+ after the usual contents of the parser header file. Thus, the
+ unqualified form replaces `%{CODE%}' for most purposes.
+
+ For Java, the default location is inside the parser class.
+
+ -- Directive: %code QUALIFIER {CODE}
+ This is the qualified form of the `%code' directive. QUALIFIER
+ identifies the purpose of CODE and thus the location(s) where
+ Bison should insert it. That is, if you need to specify
+ location-sensitive CODE that does not belong at the default
+ location selected by the unqualified `%code' form, use this form
+ instead.
+
+ For any particular qualifier or for the unqualified form, if there
+are multiple occurrences of the `%code' directive, Bison concatenates
+the specified code in the order in which it appears in the grammar file.
+
+ Not all qualifiers are accepted for all target languages. Unaccepted
+qualifiers produce an error. Some of the accepted qualifiers are:
+
+ * requires
+
+ * Language(s): C, C++
+
+ * Purpose: This is the best place to write dependency code
+ required for `YYSTYPE' and `YYLTYPE'. In other words, it's
+ the best place to define types referenced in `%union'
+ directives, and it's the best place to override Bison's
+ default `YYSTYPE' and `YYLTYPE' definitions.
+
+ * Location(s): The parser header file and the parser
+ implementation file before the Bison-generated `YYSTYPE' and
+ `YYLTYPE' definitions.
+
+ * provides
+
+ * Language(s): C, C++
+
+ * Purpose: This is the best place to write additional
+ definitions and declarations that should be provided to other
+ modules.
+
+ * Location(s): The parser header file and the parser
+ implementation file after the Bison-generated `YYSTYPE',
+ `YYLTYPE', and token definitions.
+
+ * top
+
+ * Language(s): C, C++
+
+ * Purpose: The unqualified `%code' or `%code requires' should
+ usually be more appropriate than `%code top'. However,
+ occasionally it is necessary to insert code much nearer the
+ top of the parser implementation file. For example:
+
+ %code top {
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ }
+
+ * Location(s): Near the top of the parser implementation file.
+
+ * imports
+
+ * Language(s): Java
+
+ * Purpose: This is the best place to write Java import
+ directives.
+
+ * Location(s): The parser Java file after any Java package
+ directive and before any class definitions.
+
+ Though we say the insertion locations are language-dependent, they
+are technically skeleton-dependent. Writers of non-standard skeletons
+however should choose their locations consistently with the behavior of
+the standard Bison skeletons.

+
+3.9 Multiple Parsers in the Same Program
+========================================
+
+Most programs that use Bison parse only one language and therefore
+contain only one Bison parser. But what if you want to parse more than
+one language with the same program? Then you need to avoid name
+conflicts between different definitions of functions and variables such
+as `yyparse', `yylval'. To use different parsers from the same
+compilation unit, you also need to avoid conflicts on types and macros
+(e.g., `YYSTYPE') exported in the generated header.
+
+ The easy way to do this is to define the `%define' variable
+`api.prefix'. With different `api.prefix's it is guaranteed that
+headers do not conflict when included together, and that compiled
+objects can be linked together too. Specifying `%define api.prefix
+PREFIX' (or passing the option `-Dapi.prefix=PREFIX', see *note
+Invoking Bison: Invocation.) renames the interface functions and
+variables of the Bison parser to start with PREFIX instead of `yy', and
+all the macros to start by PREFIX (i.e., PREFIX upper-cased) instead of
+`YY'.
+
+ The renamed symbols include `yyparse', `yylex', `yyerror',
+`yynerrs', `yylval', `yylloc', `yychar' and `yydebug'. If you use a
+push parser, `yypush_parse', `yypull_parse', `yypstate', `yypstate_new'
+and `yypstate_delete' will also be renamed. The renamed macros include
+`YYSTYPE', `YYLTYPE', and `YYDEBUG', which is treated specifically --
+more about this below.
+
+ For example, if you use `%define api.prefix c', the names become
+`cparse', `clex', ..., `CSTYPE', `CLTYPE', and so on.
+
+ The `%define' variable `api.prefix' works in two different ways. In
+the implementation file, it works by adding macro definitions to the
+beginning of the parser implementation file, defining `yyparse' as
+`PREFIXparse', and so on:
+
+ #define YYSTYPE CTYPE
+ #define yyparse cparse
+ #define yylval clval
+ ...
+ YYSTYPE yylval;
+ int yyparse (void);
+
+ This effectively substitutes one name for the other in the entire
+parser implementation file, thus the "original" names (`yylex',
+`YYSTYPE', ...) are also usable in the parser implementation file.
+
+ However, in the parser header file, the symbols are defined renamed,
+for instance:
+
+ extern CSTYPE clval;
+ int cparse (void);
+
+ The macro `YYDEBUG' is commonly used to enable the tracing support in
+parsers. To comply with this tradition, when `api.prefix' is used,
+`YYDEBUG' (not renamed) is used as a default value:
+
+ /* Enabling traces. */
+ #ifndef CDEBUG
+ # if defined YYDEBUG
+ # if YYDEBUG
+ # define CDEBUG 1
+ # else
+ # define CDEBUG 0
+ # endif
+ # else
+ # define CDEBUG 0
+ # endif
+ #endif
+ #if CDEBUG
+ extern int cdebug;
+ #endif
+
+
+
+ Prior to Bison 2.6, a feature similar to `api.prefix' was provided by
+the obsolete directive `%name-prefix' (*note Bison Symbols: Table of
+Symbols.) and the option `--name-prefix' (*note Bison Options::).

+that it needs to use.
+
+ Keep in mind that the parser uses many C identifiers starting with
+`yy' and `YY' for internal purposes. If you use such an identifier
+(aside from those in this manual) in an action or in epilogue in the
+grammar file, you are likely to run into trouble.

+File: bison.info, Node: Parser Function, Next: Push Parser Function, Up: Interface
+
+4.1 The Parser Function `yyparse'
+=================================
+
+You call the function `yyparse' to cause parsing to occur. This
+function reads tokens, executes actions, and ultimately returns when it
+encounters end-of-input or an unrecoverable syntax error. You can also
+write an action which directs `yyparse' to return immediately without
+reading further.
+
+ -- Function: int yyparse (void)
+ The value returned by `yyparse' is 0 if parsing was successful
+ (return is due to end-of-input).
+
+ The value is 1 if parsing failed because of invalid input, i.e.,
+ input that contains a syntax error or that causes `YYABORT' to be
+ invoked.
+
+ The value is 2 if parsing failed due to memory exhaustion.
+
+ In an action, you can cause immediate return from `yyparse' by using
+these macros:
+
+ -- Macro: YYACCEPT
+ Return immediately with value 0 (to report success).
+
+ -- Macro: YYABORT
+ Return immediately with value 1 (to report failure).
+
+ If you use a reentrant parser, you can optionally pass additional
+parameter information to it in a reentrant way. To do so, use the
+declaration `%parse-param':
+
+ -- Directive: %parse-param {ARGUMENT-DECLARATION}
+ Declare that an argument declared by the braced-code
+ ARGUMENT-DECLARATION is an additional `yyparse' argument. The
+ ARGUMENT-DECLARATION is used when declaring functions or
+ prototypes. The last identifier in ARGUMENT-DECLARATION must be
+ the argument name.
+
+ Here's an example. Write this in the parser:
+
+ %parse-param {int *nastiness}
+ %parse-param {int *randomness}
+
+Then call the parser like this:
+
+ {
+ int nastiness, randomness;
+ ... /* Store proper data in `nastiness' and `randomness'. */
+ value = yyparse (&nastiness, &randomness);
+ ...
+ }
+
+In the grammar actions, use expressions like this to refer to the data:
+
+ exp: ... { ...; *randomness += 1; ... }

+
+ You call the function `yypush_parse' to parse a single token. This

+
+ -- Function: yypstate* yypstate_new (void)

+ You call the function `yypstate_delete' to delete a parser instance.
+function is available if either the `%define api.push-pull push' or

+
+4.6 The Lexical Analyzer Function `yylex'
+=========================================
+
+The "lexical analyzer" function, `yylex', recognizes tokens from the
+input stream and returns them to the parser. Bison does not create
+this function automatically; you must write it so that `yyparse' can
+call it. The function is sometimes referred to as a lexical scanner.
+
+ In simple programs, `yylex' is often defined at the end of the Bison
+grammar file. If `yylex' is defined in a separate source file, you
+need to arrange for the token-type macro definitions to be available
+there. To do this, use the `-d' option when you run Bison, so that it
+will write these macro definitions into the separate parser header
+file, `NAME.tab.h', which you can include in the other source files
+that need it. *Note Invoking Bison: Invocation.
+
+* Menu:
+
+* Calling Convention:: How `yyparse' calls `yylex'.
+* Token Values:: How `yylex' must return the semantic value
+ of the token it has read.
+* Token Locations:: How `yylex' must return the text location
+ (line number, etc.) of the token, if the
+ actions want that.
+* Pure Calling:: How the calling convention differs in a pure parser
+ (*note A Pure (Reentrant) Parser: Pure Decl.).
+
+\1f
+File: bison.info, Node: Calling Convention, Next: Token Values, Up: Lexical
+
+4.6.1 Calling Convention for `yylex'
+------------------------------------
+
+The value that `yylex' returns must be the positive numeric code for
+the type of token it has just found; a zero or negative value signifies
+end-of-input.
+
+ When a token is referred to in the grammar rules by a name, that name
+in the parser implementation file becomes a C macro whose definition is
+the proper numeric code for that token type. So `yylex' can use the
+name to indicate that type. *Note Symbols::.
+
+ When a token is referred to in the grammar rules by a character
+literal, the numeric code for that character is also the code for the
+token type. So `yylex' can simply return that character code, possibly
+converted to `unsigned char' to avoid sign-extension. The null
+character must not be used this way, because its code is zero and that
+signifies end-of-input.
+
+ Here is an example showing these things:
+
+ int
+ yylex (void)
+ {
+ ...
+ if (c == EOF) /* Detect end-of-input. */
+ return 0;
+ ...
+ if (c == '+' || c == '-')
+ return c; /* Assume token type for `+' is '+'. */
+ ...
+ return INT; /* Return the type of the token. */
+ ...
+ }
+
+This interface has been designed so that the output from the `lex'
+utility can be used without change as the definition of `yylex'.
+
+ If the grammar uses literal string tokens, there are two ways that
+`yylex' can determine the token type codes for them:
+
+ * If the grammar defines symbolic token names as aliases for the
+ literal string tokens, `yylex' can use these symbolic names like
+ all others. In this case, the use of the literal string tokens in
+ the grammar file has no effect on `yylex'.
+
+ * `yylex' can find the multicharacter token in the `yytname' table.
+ The index of the token in the table is the token type's code. The
+ name of a multicharacter token is recorded in `yytname' with a
+ double-quote, the token's characters, and another double-quote.
+ The token's characters are escaped as necessary to be suitable as
+ input to Bison.
+
+ Here's code for looking up a multicharacter token in `yytname',
+ assuming that the characters of the token are stored in
+ `token_buffer', and assuming that the token does not contain any
+ characters like `"' that require escaping.
+
+ for (i = 0; i < YYNTOKENS; i++)
+ {
+ if (yytname[i] != 0
+ && yytname[i][0] == '"'
+ && ! strncmp (yytname[i] + 1, token_buffer,
+ strlen (token_buffer))
+ && yytname[i][strlen (token_buffer) + 1] == '"'
+ && yytname[i][strlen (token_buffer) + 2] == 0)
+ break;
+ }
+
+ The `yytname' table is generated only if you use the
+ `%token-table' declaration. *Note Decl Summary::.
+
+\1f
+File: bison.info, Node: Token Values, Next: Token Locations, Prev: Calling Convention, Up: Lexical
+
+4.6.2 Semantic Values of Tokens
+-------------------------------
+
+In an ordinary (nonreentrant) parser, the semantic value of the token
+must be stored into the global variable `yylval'. When you are using
+just one data type for semantic values, `yylval' has that type. Thus,
+if the type is `int' (the default), you might write this in `yylex':
+
+ ...
+ yylval = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ ...
+
+ When you are using multiple data types, `yylval''s type is a union
+made from the `%union' declaration (*note The Collection of Value
+Types: Union Decl.). So when you store a token's value, you must use
+the proper member of the union. If the `%union' declaration looks like
+this:
+
+ %union {
+ int intval;
+ double val;
+ symrec *tptr;
+ }
+
+then the code in `yylex' might look like this:
+
+ ...
+ yylval.intval = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ ...
+
+\1f
+File: bison.info, Node: Token Locations, Next: Pure Calling, Prev: Token Values, Up: Lexical
+
+4.6.3 Textual Locations of Tokens
+---------------------------------
+
+If you are using the `@N'-feature (*note Tracking Locations::) in
+actions to keep track of the textual locations of tokens and groupings,
+then you must provide this information in `yylex'. The function
+`yyparse' expects to find the textual location of a token just parsed
+in the global variable `yylloc'. So `yylex' must store the proper data
+in that variable.
+
+ By default, the value of `yylloc' is a structure and you need only
+initialize the members that are going to be used by the actions. The
+four members are called `first_line', `first_column', `last_line' and
+`last_column'. Note that the use of this feature makes the parser
+noticeably slower.
+
+ The data type of `yylloc' has the name `YYLTYPE'.
+
+\1f
+File: bison.info, Node: Pure Calling, Prev: Token Locations, Up: Lexical
+
+4.6.4 Calling Conventions for Pure Parsers
+------------------------------------------
+
+When you use the Bison declaration `%define api.pure' to request a
+pure, reentrant parser, the global communication variables `yylval' and
+`yylloc' cannot be used. (*Note A Pure (Reentrant) Parser: Pure Decl.)
+In such parsers the two global variables are replaced by pointers
+passed as arguments to `yylex'. You must declare them as shown here,
+and pass the information back by storing it through those pointers.
+
+ int
+ yylex (YYSTYPE *lvalp, YYLTYPE *llocp)
+ {
+ ...
+ *lvalp = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ ...
+ }
+
+ If the grammar file does not use the `@' constructs to refer to
+textual locations, then the type `YYLTYPE' will not be defined. In
+this case, omit the second argument; `yylex' will be called with only
+one argument.
+
+ If you wish to pass the additional parameter data to `yylex', use
+`%lex-param' just like `%parse-param' (*note Parser Function::).
+
+ -- Directive: lex-param {ARGUMENT-DECLARATION}
+ Declare that the braced-code ARGUMENT-DECLARATION is an additional
+ `yylex' argument declaration.
+
+ For instance:
+
+ %parse-param {int *nastiness}
+ %lex-param {int *nastiness}
+ %parse-param {int *randomness}
+
+results in the following signatures:
+
+ int yylex (int *nastiness);
+ int yyparse (int *nastiness, int *randomness);
+
+ If `%define api.pure' is added:
+
+ int yylex (YYSTYPE *lvalp, int *nastiness);
+ int yyparse (int *nastiness, int *randomness);
+
+and finally, if both `%define api.pure' and `%locations' are used:
+
+ int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness);
+ int yyparse (int *nastiness, int *randomness);
+

+File: bison.info, Node: Error Reporting, Next: Action Features, Prev: Lexical, Up: Interface
+
+4.7 The Error Reporting Function `yyerror'
+==========================================
+
+The Bison parser detects a "syntax error" or "parse error" whenever it
+reads a token which cannot satisfy any syntax rule. An action in the
+grammar can also explicitly proclaim an error, using the macro
+`YYERROR' (*note Special Features for Use in Actions: Action Features.).
+
+ The Bison parser expects to report the error by calling an error
+reporting function named `yyerror', which you must supply. It is
+called by `yyparse' whenever a syntax error is found, and it receives
+one argument. For a syntax error, the string is normally
+`"syntax error"'.
+
+ If you invoke the directive `%error-verbose' in the Bison
+declarations section (*note The Bison Declarations Section: Bison
+Declarations.), then Bison provides a more verbose and specific error
+message string instead of just plain `"syntax error"'. However, that
+message sometimes contains incorrect information if LAC is not enabled
+(*note LAC::).
+
+ The parser can detect one other kind of error: memory exhaustion.
+This can happen when the input contains constructions that are very
+deeply nested. It isn't likely you will encounter this, since the Bison
+parser normally extends its stack automatically up to a very large
+limit. But if memory is exhausted, `yyparse' calls `yyerror' in the
+usual fashion, except that the argument string is `"memory exhausted"'.
+
+ In some cases diagnostics like `"syntax error"' are translated
+automatically from English to some other language before they are
+passed to `yyerror'. *Note Internationalization::.
+
+ The following definition suffices in simple programs:
+
+ void
+ yyerror (char const *s)
+ {
+ fprintf (stderr, "%s\n", s);
+ }
+
+ After `yyerror' returns to `yyparse', the latter will attempt error
+recovery if you have written suitable error recovery grammar rules
+(*note Error Recovery::). If recovery is impossible, `yyparse' will
+immediately return 1.
+
+ Obviously, in location tracking pure parsers, `yyerror' should have
+an access to the current location. This is indeed the case for the GLR
+parsers, but not for the Yacc parser, for historical reasons. I.e., if
+`%locations %define api.pure' is passed then the prototypes for
+`yyerror' are:
+
+ void yyerror (char const *msg); /* Yacc parsers. */
+ void yyerror (YYLTYPE *locp, char const *msg); /* GLR parsers. */
+
+ If `%parse-param {int *nastiness}' is used, then:
+
+ void yyerror (int *nastiness, char const *msg); /* Yacc parsers. */
+ void yyerror (int *nastiness, char const *msg); /* GLR parsers. */
+
+ Finally, GLR and Yacc parsers share the same `yyerror' calling
+convention for absolutely pure parsers, i.e., when the calling
+convention of `yylex' _and_ the calling convention of `%define
+api.pure' are pure. I.e.:
+
+ /* Location tracking. */
+ %locations
+ /* Pure yylex. */
+ %define api.pure
+ %lex-param {int *nastiness}
+ /* Pure yyparse. */
+ %parse-param {int *nastiness}
+ %parse-param {int *randomness}
+
+results in the following signatures for all the parser kinds:
+
+ int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness);
+ int yyparse (int *nastiness, int *randomness);
+ void yyerror (YYLTYPE *locp,
+ int *nastiness, int *randomness,
+ char const *msg);
+
+The prototypes are only indications of how the code produced by Bison
+uses `yyerror'. Bison-generated code always ignores the returned
+value, so `yyerror' can return any type, including `void'. Also,
+`yyerror' can be a variadic function; that is why the message is always
+passed last.
+
+ Traditionally `yyerror' returns an `int' that is always ignored, but
+this is purely for historical reasons, and `void' is preferable since
+it more accurately describes the return type for `yyerror'.
+
+ The variable `yynerrs' contains the number of syntax errors reported
+so far. Normally this variable is global; but if you request a pure
+parser (*note A Pure (Reentrant) Parser: Pure Decl.) then it is a
+local variable which only the actions can access.

+
+4.8 Special Features for Use in Actions
+=======================================
+
+Here is a table of Bison constructs, variables and macros that are
+useful in actions.
+
+ -- Variable: $$
+ Acts like a variable that contains the semantic value for the
+ grouping made by the current rule. *Note Actions::.
+
+ -- Variable: $N
+ Acts like a variable that contains the semantic value for the Nth
+ component of the current rule. *Note Actions::.
+
+ -- Variable: $<TYPEALT>$
+ Like `$$' but specifies alternative TYPEALT in the union specified
+ by the `%union' declaration. *Note Data Types of Values in
+ Actions: Action Types.
+
+ -- Variable: $<TYPEALT>N
+ Like `$N' but specifies alternative TYPEALT in the union specified
+ by the `%union' declaration. *Note Data Types of Values in
+ Actions: Action Types.
+
+ -- Macro: YYABORT `;'
+ Return immediately from `yyparse', indicating failure. *Note The
+ Parser Function `yyparse': Parser Function.
+
+ -- Macro: YYACCEPT `;'
+ Return immediately from `yyparse', indicating success. *Note The
+ Parser Function `yyparse': Parser Function.
+
+ -- Macro: YYBACKUP (TOKEN, VALUE)`;'
+ Unshift a token. This macro is allowed only for rules that reduce
+ a single value, and only when there is no lookahead token. It is
+ also disallowed in GLR parsers. It installs a lookahead token
+ with token type TOKEN and semantic value VALUE; then it discards
+ the value that was going to be reduced by this rule.
+
+ If the macro is used when it is not valid, such as when there is a
+ lookahead token already, then it reports a syntax error with a
+ message `cannot back up' and performs ordinary error recovery.
+
+ In either case, the rest of the action is not executed.
+
+ -- Macro: YYEMPTY
+ Value stored in `yychar' when there is no lookahead token.
+
+ -- Macro: YYEOF
+ Value stored in `yychar' when the lookahead is the end of the input
+ stream.
+
+ -- Macro: YYERROR `;'
+ Cause an immediate syntax error. This statement initiates error
+ recovery just as if the parser itself had detected an error;
+ however, it does not call `yyerror', and does not print any
+ message. If you want to print an error message, call `yyerror'
+ explicitly before the `YYERROR;' statement. *Note Error
+ Recovery::.
+
+ -- Macro: YYRECOVERING
+ The expression `YYRECOVERING ()' yields 1 when the parser is
+ recovering from a syntax error, and 0 otherwise. *Note Error
+ Recovery::.
+
+ -- Variable: yychar
+ Variable containing either the lookahead token, or `YYEOF' when the
+ lookahead is the end of the input stream, or `YYEMPTY' when no
+ lookahead has been performed so the next token is not yet known.
+ Do not modify `yychar' in a deferred semantic action (*note GLR
+ Semantic Actions::). *Note Lookahead Tokens: Lookahead.
+
+ -- Macro: yyclearin `;'
+ Discard the current lookahead token. This is useful primarily in
+ error rules. Do not invoke `yyclearin' in a deferred semantic
+ action (*note GLR Semantic Actions::). *Note Error Recovery::.
+
+ -- Macro: yyerrok `;'
+ Resume generating error messages immediately for subsequent syntax
+ errors. This is useful primarily in error rules. *Note Error
+ Recovery::.
+
+ -- Variable: yylloc
+ Variable containing the lookahead token location when `yychar' is
+ not set to `YYEMPTY' or `YYEOF'. Do not modify `yylloc' in a
+ deferred semantic action (*note GLR Semantic Actions::). *Note
+ Actions and Locations: Actions and Locations.
+
+ -- Variable: yylval
+ Variable containing the lookahead token semantic value when
+ `yychar' is not set to `YYEMPTY' or `YYEOF'. Do not modify
+ `yylval' in a deferred semantic action (*note GLR Semantic
+ Actions::). *Note Actions: Actions.
+
+ -- Value: @$
+ Acts like a structure variable containing information on the
+ textual location of the grouping made by the current rule. *Note
+ Tracking Locations::.
+
+
+ -- Value: @N
+ Acts like a structure variable containing information on the
+ textual location of the Nth component of the current rule. *Note
+ Tracking Locations::.

+
+4.9 Parser Internationalization
+===============================
+
+A Bison-generated parser can print diagnostics, including error and
+tracing messages. By default, they appear in English. However, Bison
+also supports outputting diagnostics in the user's native language. To
+make this work, the user should set the usual environment variables.
+*Note The User's View: (gettext)Users. For example, the shell command
+`export LC_ALL=fr_CA.UTF-8' might set the user's locale to French
+Canadian using the UTF-8 encoding. The exact set of available locales
+depends on the user's installation.
+
+ The maintainer of a package that uses a Bison-generated parser
+enables the internationalization of the parser's output through the
+following steps. Here we assume a package that uses GNU Autoconf and
+GNU Automake.
+
+ 1. Into the directory containing the GNU Autoconf macros used by the
+ package--often called `m4'--copy the `bison-i18n.m4' file
+ installed by Bison under `share/aclocal/bison-i18n.m4' in Bison's
+ installation directory. For example:
+
+ cp /usr/local/share/aclocal/bison-i18n.m4 m4/bison-i18n.m4
+
+ 2. In the top-level `configure.ac', after the `AM_GNU_GETTEXT'
+ invocation, add an invocation of `BISON_I18N'. This macro is
+ defined in the file `bison-i18n.m4' that you copied earlier. It
+ causes `configure' to find the value of the `BISON_LOCALEDIR'
+ variable, and it defines the source-language symbol `YYENABLE_NLS'
+ to enable translations in the Bison-generated parser.
+
+ 3. In the `main' function of your program, designate the directory
+ containing Bison's runtime message catalog, through a call to
+ `bindtextdomain' with domain name `bison-runtime'. For example:
+
+ bindtextdomain ("bison-runtime", BISON_LOCALEDIR);
+
+ Typically this appears after any other call `bindtextdomain
+ (PACKAGE, LOCALEDIR)' that your package already has. Here we rely
+ on `BISON_LOCALEDIR' to be defined as a string through the
+ `Makefile'.
+
+ 4. In the `Makefile.am' that controls the compilation of the `main'
+ function, make `BISON_LOCALEDIR' available as a C preprocessor
+ macro, either in `DEFS' or in `AM_CPPFLAGS'. For example:
+
+ DEFS = @DEFS@ -DBISON_LOCALEDIR='"$(BISON_LOCALEDIR)"'
+
+ or:
+
+ AM_CPPFLAGS = -DBISON_LOCALEDIR='"$(BISON_LOCALEDIR)"'
+
+ 5. Finally, invoke the command `autoreconf' to generate the build
+ infrastructure.

+
+5 The Bison Parser Algorithm
+****************************
+
+As Bison reads tokens, it pushes them onto a stack along with their
+semantic values. The stack is called the "parser stack". Pushing a
+token is traditionally called "shifting".
+
+ For example, suppose the infix calculator has read `1 + 5 *', with a
+`3' to come. The stack will have four elements, one for each token
+that was shifted.
+
+ But the stack does not always have an element for each token read.
+When the last N tokens and groupings shifted match the components of a
+grammar rule, they can be combined according to that rule. This is
+called "reduction". Those tokens and groupings are replaced on the
+stack by a single grouping whose symbol is the result (left hand side)
+of that rule. Running the rule's action is part of the process of
+reduction, because this is what computes the semantic value of the
+resulting grouping.
+
+ For example, if the infix calculator's parser stack contains this:
+
+ 1 + 5 * 3
+
+and the next input token is a newline character, then the last three
+elements can be reduced to 15 via the rule:
+
+ expr: expr '*' expr;
+
+Then the stack contains just these three elements:
+
+ 1 + 15
+
+At this point, another reduction can be made, resulting in the single
+value 16. Then the newline token can be shifted.
+
+ The parser tries, by shifts and reductions, to reduce the entire
+input down to a single grouping whose symbol is the grammar's
+start-symbol (*note Languages and Context-Free Grammars: Language and
+Grammar.).
+
+ This kind of parser is known in the literature as a bottom-up parser.

+
+5.1 Lookahead Tokens
+====================
+
+The Bison parser does _not_ always reduce immediately as soon as the
+last N tokens and groupings match a rule. This is because such a
+simple strategy is inadequate to handle most languages. Instead, when a
+reduction is possible, the parser sometimes "looks ahead" at the next
+token in order to decide what to do.
+
+ When a token is read, it is not immediately shifted; first it
+becomes the "lookahead token", which is not on the stack. Now the
+parser can perform one or more reductions of tokens and groupings on
+the stack, while the lookahead token remains off to the side. When no
+more reductions should take place, the lookahead token is shifted onto
+the stack. This does not mean that all possible reductions have been
+done; depending on the token type of the lookahead token, some rules
+may choose to delay their application.
+
+ Here is a simple case where lookahead is needed. These three rules
+define expressions which contain binary addition operators and postfix
+unary factorial operators (`!'), and allow parentheses for grouping.
+
+ expr:
+ term '+' expr
+ | term
+ ;
+
+ term:
+ '(' expr ')'
+ | term '!'
+ | NUMBER
+ ;
+
+ Suppose that the tokens `1 + 2' have been read and shifted; what
+should be done? If the following token is `)', then the first three
+tokens must be reduced to form an `expr'. This is the only valid
+course, because shifting the `)' would produce a sequence of symbols
+`term ')'', and no rule allows this.
+
+ If the following token is `!', then it must be shifted immediately so
+that `2 !' can be reduced to make a `term'. If instead the parser were
+to reduce before shifting, `1 + 2' would become an `expr'. It would
+then be impossible to shift the `!' because doing so would produce on
+the stack the sequence of symbols `expr '!''. No rule allows that
+sequence.
+
+ The lookahead token is stored in the variable `yychar'. Its
+semantic value and location, if any, are stored in the variables
+`yylval' and `yylloc'. *Note Special Features for Use in Actions:
+Action Features.

+File: bison.info, Node: Shift/Reduce, Next: Precedence, Prev: Lookahead, Up: Algorithm
+
+5.2 Shift/Reduce Conflicts
+==========================
+
+Suppose we are parsing a language which has if-then and if-then-else
+statements, with a pair of rules like this:
+
+ if_stmt:
+ IF expr THEN stmt
+ | IF expr THEN stmt ELSE stmt
+ ;
+
+Here we assume that `IF', `THEN' and `ELSE' are terminal symbols for
+specific keyword tokens.
+
+ When the `ELSE' token is read and becomes the lookahead token, the
+contents of the stack (assuming the input is valid) are just right for
+reduction by the first rule. But it is also legitimate to shift the
+`ELSE', because that would lead to eventual reduction by the second
+rule.
+
+ This situation, where either a shift or a reduction would be valid,
+is called a "shift/reduce conflict". Bison is designed to resolve
+these conflicts by choosing to shift, unless otherwise directed by
+operator precedence declarations. To see the reason for this, let's
+contrast it with the other alternative.
+
+ Since the parser prefers to shift the `ELSE', the result is to attach
+the else-clause to the innermost if-statement, making these two inputs
+equivalent:
+
+ if x then if y then win (); else lose;
+
+ if x then do; if y then win (); else lose; end;
+
+ But if the parser chose to reduce when possible rather than shift,
+the result would be to attach the else-clause to the outermost
+if-statement, making these two inputs equivalent:
+
+ if x then if y then win (); else lose;
+
+ if x then do; if y then win (); end; else lose;
+
+ The conflict exists because the grammar as written is ambiguous:
+either parsing of the simple nested if-statement is legitimate. The
+established convention is that these ambiguities are resolved by
+attaching the else-clause to the innermost if-statement; this is what
+Bison accomplishes by choosing to shift rather than reduce. (It would
+ideally be cleaner to write an unambiguous grammar, but that is very
+hard to do in this case.) This particular ambiguity was first
+encountered in the specifications of Algol 60 and is called the
+"dangling `else'" ambiguity.
+
+ To avoid warnings from Bison about predictable, legitimate
+shift/reduce conflicts, use the `%expect N' declaration. There will be
+no warning as long as the number of shift/reduce conflicts is exactly
+N, and Bison will report an error if there is a different number.
+*Note Suppressing Conflict Warnings: Expect Decl.
+
+ The definition of `if_stmt' above is solely to blame for the
+conflict, but the conflict does not actually appear without additional
+rules. Here is a complete Bison grammar file that actually manifests
+the conflict:
+
+ %token IF THEN ELSE variable
+ %%
+ stmt:
+ expr
+ | if_stmt
+ ;
+
+ if_stmt:
+ IF expr THEN stmt
+ | IF expr THEN stmt ELSE stmt
+ ;
+
+ expr:
+ variable
+ ;

+
+5.3 Operator Precedence
+=======================
+
+Another situation where shift/reduce conflicts appear is in arithmetic
+expressions. Here shifting is not always the preferred resolution; the
+Bison declarations for operator precedence allow you to specify when to
+shift and when to reduce.

+* Why Precedence:: An example showing why precedence is needed.
+* Using Precedence:: How to specify precedence in Bison grammars.
+* Precedence Examples:: How these features are used in the previous example.
+* How Precedence:: How they work.
+
+\1f
+File: bison.info, Node: Why Precedence, Next: Using Precedence, Up: Precedence
+
+5.3.1 When Precedence is Needed
+-------------------------------
+
+Consider the following ambiguous grammar fragment (ambiguous because the
+input `1 - 2 * 3' can be parsed in two different ways):
+
+ expr:
+ expr '-' expr
+ | expr '*' expr
+ | expr '<' expr
+ | '(' expr ')'
+ ...
+ ;
+
+Suppose the parser has seen the tokens `1', `-' and `2'; should it
+reduce them via the rule for the subtraction operator? It depends on
+the next token. Of course, if the next token is `)', we must reduce;
+shifting is invalid because no single rule can reduce the token
+sequence `- 2 )' or anything starting with that. But if the next token
+is `*' or `<', we have a choice: either shifting or reduction would
+allow the parse to complete, but with different results.
+
+ To decide which one Bison should do, we must consider the results.
+If the next operator token OP is shifted, then it must be reduced first
+in order to permit another opportunity to reduce the difference. The
+result is (in effect) `1 - (2 OP 3)'. On the other hand, if the
+subtraction is reduced before shifting OP, the result is
+`(1 - 2) OP 3'. Clearly, then, the choice of shift or reduce should
+depend on the relative precedence of the operators `-' and OP: `*'
+should be shifted first, but not `<'.
+
+ What about input such as `1 - 2 - 5'; should this be `(1 - 2) - 5'
+or should it be `1 - (2 - 5)'? For most operators we prefer the
+former, which is called "left association". The latter alternative,
+"right association", is desirable for assignment operators. The choice
+of left or right association is a matter of whether the parser chooses
+to shift or reduce when the stack contains `1 - 2' and the lookahead
+token is `-': shifting makes right-associativity.
+
+\1f
+File: bison.info, Node: Using Precedence, Next: Precedence Examples, Prev: Why Precedence, Up: Precedence
+
+5.3.2 Specifying Operator Precedence
+------------------------------------
+
+Bison allows you to specify these choices with the operator precedence
+declarations `%left' and `%right'. Each such declaration contains a
+list of tokens, which are operators whose precedence and associativity
+is being declared. The `%left' declaration makes all those operators
+left-associative and the `%right' declaration makes them
+right-associative. A third alternative is `%nonassoc', which declares
+that it is a syntax error to find the same operator twice "in a row".
+
+ The relative precedence of different operators is controlled by the
+order in which they are declared. The first `%left' or `%right'
+declaration in the file declares the operators whose precedence is
+lowest, the next such declaration declares the operators whose
+precedence is a little higher, and so on.
+
+\1f
+File: bison.info, Node: Precedence Examples, Next: How Precedence, Prev: Using Precedence, Up: Precedence
+
+5.3.3 Precedence Examples
+-------------------------
+
+In our example, we would want the following declarations:
+
+ %left '<'
+ %left '-'
+ %left '*'
+
+ In a more complete example, which supports other operators as well,
+we would declare them in groups of equal precedence. For example,
+`'+'' is declared with `'-'':
+
+ %left '<' '>' '=' NE LE GE
+ %left '+' '-'
+ %left '*' '/'
+
+(Here `NE' and so on stand for the operators for "not equal" and so on.
+We assume that these tokens are more than one character long and
+therefore are represented by names, not character literals.)
+
+\1f
+File: bison.info, Node: How Precedence, Prev: Precedence Examples, Up: Precedence
+
+5.3.4 How Precedence Works
+--------------------------
+
+The first effect of the precedence declarations is to assign precedence
+levels to the terminal symbols declared. The second effect is to assign
+precedence levels to certain rules: each rule gets its precedence from
+the last terminal symbol mentioned in the components. (You can also
+specify explicitly the precedence of a rule. *Note Context-Dependent
+Precedence: Contextual Precedence.)
+
+ Finally, the resolution of conflicts works by comparing the
+precedence of the rule being considered with that of the lookahead
+token. If the token's precedence is higher, the choice is to shift.
+If the rule's precedence is higher, the choice is to reduce. If they
+have equal precedence, the choice is made based on the associativity of
+that precedence level. The verbose output file made by `-v' (*note
+Invoking Bison: Invocation.) says how each conflict was resolved.
+
+ Not all rules and not all tokens have precedence. If either the
+rule or the lookahead token has no precedence, then the default is to
+shift.
+
+\1f
+File: bison.info, Node: Contextual Precedence, Next: Parser States, Prev: Precedence, Up: Algorithm
+
+5.4 Context-Dependent Precedence
+================================
+
+Often the precedence of an operator depends on the context. This sounds
+outlandish at first, but it is really very common. For example, a minus
+sign typically has a very high precedence as a unary operator, and a
+somewhat lower precedence (lower than multiplication) as a binary
+operator.
+
+ The Bison precedence declarations, `%left', `%right' and
+`%nonassoc', can only be used once for a given token; so a token has
+only one precedence declared in this way. For context-dependent
+precedence, you need to use an additional mechanism: the `%prec'
+modifier for rules.
+
+ The `%prec' modifier declares the precedence of a particular rule by
+specifying a terminal symbol whose precedence should be used for that
+rule. It's not necessary for that symbol to appear otherwise in the
+rule. The modifier's syntax is:
+
+ %prec TERMINAL-SYMBOL
+
+and it is written after the components of the rule. Its effect is to
+assign the rule the precedence of TERMINAL-SYMBOL, overriding the
+precedence that would be deduced for it in the ordinary way. The
+altered rule precedence then affects how conflicts involving that rule
+are resolved (*note Operator Precedence: Precedence.).
+
+ Here is how `%prec' solves the problem of unary minus. First,
+declare a precedence for a fictitious terminal symbol named `UMINUS'.
+There are no tokens of this type, but the symbol serves to stand for its
+precedence:
+
+ ...
+ %left '+' '-'
+ %left '*'
+ %left UMINUS
+
+ Now the precedence of `UMINUS' can be used in specific rules:
+
+ exp:
+ ...
+ | exp '-' exp
+ ...
+ | '-' exp %prec UMINUS
+
+\1f

+
+5.5 Parser States
+=================
+
+The function `yyparse' is implemented using a finite-state machine.
+The values pushed on the parser stack are not simply token type codes;
+they represent the entire sequence of terminal and nonterminal symbols
+at or near the top of the stack. The current state collects all the
+information about previous input which is relevant to deciding what to
+do next.
+
+ Each time a lookahead token is read, the current parser state
+together with the type of lookahead token are looked up in a table.
+This table entry can say, "Shift the lookahead token." In this case,
+it also specifies the new parser state, which is pushed onto the top of
+the parser stack. Or it can say, "Reduce using rule number N." This
+means that a certain number of tokens or groupings are taken off the
+top of the stack, and replaced by one grouping. In other words, that
+number of states are popped from the stack, and one new state is pushed.
+
+ There is one other alternative: the table can say that the lookahead
+token is erroneous in the current state. This causes error processing
+to begin (*note Error Recovery::).
+
+\1f
+File: bison.info, Node: Reduce/Reduce, Next: Mysterious Conflicts, Prev: Parser States, Up: Algorithm
+
+5.6 Reduce/Reduce Conflicts
+===========================
+
+A reduce/reduce conflict occurs if there are two or more rules that
+apply to the same sequence of input. This usually indicates a serious
+error in the grammar.
+
+ For example, here is an erroneous attempt to define a sequence of
+zero or more `word' groupings.
+
+ sequence:
+ /* empty */ { printf ("empty sequence\n"); }
+ | maybeword
+ | sequence word { printf ("added word %s\n", $2); }
+ ;
+
+ maybeword:
+ /* empty */ { printf ("empty maybeword\n"); }
+ | word { printf ("single word %s\n", $1); }
+ ;
+
+The error is an ambiguity: there is more than one way to parse a single
+`word' into a `sequence'. It could be reduced to a `maybeword' and
+then into a `sequence' via the second rule. Alternatively,
+nothing-at-all could be reduced into a `sequence' via the first rule,
+and this could be combined with the `word' using the third rule for
+`sequence'.
+
+ There is also more than one way to reduce nothing-at-all into a
+`sequence'. This can be done directly via the first rule, or
+indirectly via `maybeword' and then the second rule.
+
+ You might think that this is a distinction without a difference,
+because it does not change whether any particular input is valid or
+not. But it does affect which actions are run. One parsing order runs
+the second rule's action; the other runs the first rule's action and
+the third rule's action. In this example, the output of the program
+changes.
+
+ Bison resolves a reduce/reduce conflict by choosing to use the rule
+that appears first in the grammar, but it is very risky to rely on
+this. Every reduce/reduce conflict must be studied and usually
+eliminated. Here is the proper way to define `sequence':
+
+ sequence:
+ /* empty */ { printf ("empty sequence\n"); }
+ | sequence word { printf ("added word %s\n", $2); }
+ ;
+
+ Here is another common error that yields a reduce/reduce conflict:
+
+ sequence:
+ /* empty */
+ | sequence words
+ | sequence redirects
+ ;
+
+ words:
+ /* empty */
+ | words word
+ ;
+
+ redirects:
+ /* empty */
+ | redirects redirect
+ ;
+
+The intention here is to define a sequence which can contain either
+`word' or `redirect' groupings. The individual definitions of
+`sequence', `words' and `redirects' are error-free, but the three
+together make a subtle ambiguity: even an empty input can be parsed in
+infinitely many ways!
+
+ Consider: nothing-at-all could be a `words'. Or it could be two
+`words' in a row, or three, or any number. It could equally well be a
+`redirects', or two, or any number. Or it could be a `words' followed
+by three `redirects' and another `words'. And so on.
+
+ Here are two ways to correct these rules. First, to make it a
+single level of sequence:
+
+ sequence:
+ /* empty */
+ | sequence word
+ | sequence redirect
+ ;
+
+ Second, to prevent either a `words' or a `redirects' from being
+empty:
+
+ sequence:
+ /* empty */
+ | sequence words
+ | sequence redirects
+ ;
+
+ words:
+ word
+ | words word
+ ;
+
+ redirects:

+
+5.7 Mysterious Conflicts
+========================
+
+Sometimes reduce/reduce conflicts can occur that don't look warranted.
+Here is an example:
+
+ %token ID
+
+ %%
+ def: param_spec return_spec ',';
+ param_spec:
+ type
+ | name_list ':' type
+ ;
+ return_spec:
+ type
+ | name ':' type
+ ;
+ type: ID;
+ name: ID;
+ name_list:
+ name
+ | name ',' name_list
+ ;
+
+ It would seem that this grammar can be parsed with only a single
+token of lookahead: when a `param_spec' is being read, an `ID' is a
+`name' if a comma or colon follows, or a `type' if another `ID'
+follows. In other words, this grammar is LR(1).
+
+ However, for historical reasons, Bison cannot by default handle all
+LR(1) grammars. In this grammar, two contexts, that after an `ID' at
+the beginning of a `param_spec' and likewise at the beginning of a
+`return_spec', are similar enough that Bison assumes they are the same.
+They appear similar because the same set of rules would be active--the
+rule for reducing to a `name' and that for reducing to a `type'. Bison
+is unable to determine at that stage of processing that the rules would
+require different lookahead tokens in the two contexts, so it makes a
+single parser state for them both. Combining the two contexts causes a
+conflict later. In parser terminology, this occurrence means that the
+grammar is not LALR(1).
+
+ For many practical grammars (specifically those that fall into the
+non-LR(1) class), the limitations of LALR(1) result in difficulties
+beyond just mysterious reduce/reduce conflicts. The best way to fix
+all these problems is to select a different parser table construction
+algorithm. Either IELR(1) or canonical LR(1) would suffice, but the
+former is more efficient and easier to debug during development. *Note
+LR Table Construction::, for details. (Bison's IELR(1) and canonical
+LR(1) implementations are experimental. More user feedback will help
+to stabilize them.)
+
+ If you instead wish to work around LALR(1)'s limitations, you can
+often fix a mysterious conflict by identifying the two parser states
+that are being confused, and adding something to make them look
+distinct. In the above example, adding one rule to `return_spec' as
+follows makes the problem go away:
+
+ %token BOGUS
+ ...
+ %%
+ ...
+ return_spec:
+ type
+ | name ':' type
+ | ID BOGUS /* This rule is never used. */
+ ;
+
+ This corrects the problem because it introduces the possibility of an
+additional active rule in the context after the `ID' at the beginning of
+`return_spec'. This rule is not active in the corresponding context in
+a `param_spec', so the two contexts receive distinct parser states. As
+long as the token `BOGUS' is never generated by `yylex', the added rule
+cannot alter the way actual input is parsed.
+
+ In this particular example, there is another way to solve the
+problem: rewrite the rule for `return_spec' to use `ID' directly
+instead of via `name'. This also causes the two confusing contexts to
+have different sets of active rules, because the one for `return_spec'
+activates the altered rule for `return_spec' rather than the one for
+`name'.
+
+ param_spec:
+ type
+ | name_list ':' type
+ ;
+ return_spec:
+ type
+ | ID ':' type

+
+5.8 Tuning LR
+=============
+
+The default behavior of Bison's LR-based parsers is chosen mostly for
+historical reasons, but that behavior is often not robust. For
+example, in the previous section, we discussed the mysterious conflicts
+that can be produced by LALR(1), Bison's default parser table
+construction algorithm. Another example is Bison's `%error-verbose'
+directive, which instructs the generated parser to produce verbose
+syntax error messages, which can sometimes contain incorrect
+information.
+
+ In this section, we explore several modern features of Bison that
+allow you to tune fundamental aspects of the generated LR-based
+parsers. Some of these features easily eliminate shortcomings like
+those mentioned above. Others can be helpful purely for understanding
+your parser.
+
+ Most of the features discussed in this section are still
+experimental. More user feedback will help to stabilize them.

+File: bison.info, Node: LR Table Construction, Next: Default Reductions, Up: Tuning LR
+
+5.8.1 LR Table Construction
+---------------------------
+
+For historical reasons, Bison constructs LALR(1) parser tables by
+default. However, LALR does not possess the full language-recognition
+power of LR. As a result, the behavior of parsers employing LALR
+parser tables is often mysterious. We presented a simple example of
+this effect in *note Mysterious Conflicts::.
+
+ As we also demonstrated in that example, the traditional approach to
+eliminating such mysterious behavior is to restructure the grammar.
+Unfortunately, doing so correctly is often difficult. Moreover, merely
+discovering that LALR causes mysterious behavior in your parser can be
+difficult as well.
+
+ Fortunately, Bison provides an easy way to eliminate the possibility
+of such mysterious behavior altogether. You simply need to activate a
+more powerful parser table construction algorithm by using the `%define
+lr.type' directive.
+
+ -- Directive: %define lr.type TYPE
+ Specify the type of parser tables within the LR(1) family. The
+ accepted values for TYPE are:
+
+ * `lalr' (default)
+
+ * `ielr'
+
+ * `canonical-lr'
+
+ (This feature is experimental. More user feedback will help to
+ stabilize it.)
+
+ For example, to activate IELR, you might add the following directive
+to you grammar file:
+
+ %define lr.type ielr
+
+For the example in *note Mysterious Conflicts::, the mysterious
+conflict is then eliminated, so there is no need to invest time in
+comprehending the conflict or restructuring the grammar to fix it. If,
+during future development, the grammar evolves such that all mysterious
+behavior would have disappeared using just LALR, you need not fear that
+continuing to use IELR will result in unnecessarily large parser tables.
+That is, IELR generates LALR tables when LALR (using a deterministic
+parsing algorithm) is sufficient to support the full
+language-recognition power of LR. Thus, by enabling IELR at the start
+of grammar development, you can safely and completely eliminate the
+need to consider LALR's shortcomings.
+
+ While IELR is almost always preferable, there are circumstances
+where LALR or the canonical LR parser tables described by Knuth (*note
+Knuth 1965: Bibliography.) can be useful. Here we summarize the
+relative advantages of each parser table construction algorithm within
+Bison:
+
+ * LALR
+
+ There are at least two scenarios where LALR can be worthwhile:
+
+ * GLR without static conflict resolution.
+
+ When employing GLR parsers (*note GLR Parsers::), if you do
+ not resolve any conflicts statically (for example, with
+ `%left' or `%prec'), then the parser explores all potential
+ parses of any given input. In this case, the choice of
+ parser table construction algorithm is guaranteed not to alter
+ the language accepted by the parser. LALR parser tables are
+ the smallest parser tables Bison can currently construct, so
+ they may then be preferable. Nevertheless, once you begin to
+ resolve conflicts statically, GLR behaves more like a
+ deterministic parser in the syntactic contexts where those
+ conflicts appear, and so either IELR or canonical LR can then
+ be helpful to avoid LALR's mysterious behavior.
+
+ * Malformed grammars.
+
+ Occasionally during development, an especially malformed
+ grammar with a major recurring flaw may severely impede the
+ IELR or canonical LR parser table construction algorithm.
+ LALR can be a quick way to construct parser tables in order
+ to investigate such problems while ignoring the more subtle
+ differences from IELR and canonical LR.
+
+ * IELR
+
+ IELR (Inadequacy Elimination LR) is a minimal LR algorithm. That
+ is, given any grammar (LR or non-LR), parsers using IELR or
+ canonical LR parser tables always accept exactly the same set of
+ sentences. However, like LALR, IELR merges parser states during
+ parser table construction so that the number of parser states is
+ often an order of magnitude less than for canonical LR. More
+ importantly, because canonical LR's extra parser states may contain
+ duplicate conflicts in the case of non-LR grammars, the number of
+ conflicts for IELR is often an order of magnitude less as well.
+ This effect can significantly reduce the complexity of developing
+ a grammar.
+
+ * Canonical LR
+
+ While inefficient, canonical LR parser tables can be an
+ interesting means to explore a grammar because they possess a
+ property that IELR and LALR tables do not. That is, if
+ `%nonassoc' is not used and default reductions are left disabled
+ (*note Default Reductions::), then, for every left context of
+ every canonical LR state, the set of tokens accepted by that state
+ is guaranteed to be the exact set of tokens that is syntactically
+ acceptable in that left context. It might then seem that an
+ advantage of canonical LR parsers in production is that, under the
+ above constraints, they are guaranteed to detect a syntax error as
+ soon as possible without performing any unnecessary reductions.
+ However, IELR parsers that use LAC are also able to achieve this
+ behavior without sacrificing `%nonassoc' or default reductions.
+ For details and a few caveats of LAC, *note LAC::.
+
+ For a more detailed exposition of the mysterious behavior in LALR
+parsers and the benefits of IELR, *note Denny 2008 March: Bibliography,
+and *note Denny 2010 November: Bibliography.

+
+5.8.2 Default Reductions
+------------------------
+
+After parser table construction, Bison identifies the reduction with the
+largest lookahead set in each parser state. To reduce the size of the
+parser state, traditional Bison behavior is to remove that lookahead
+set and to assign that reduction to be the default parser action. Such
+a reduction is known as a "default reduction".
+
+ Default reductions affect more than the size of the parser tables.
+They also affect the behavior of the parser:
+
+ * Delayed `yylex' invocations.
+
+ A "consistent state" is a state that has only one possible parser
+ action. If that action is a reduction and is encoded as a default
+ reduction, then that consistent state is called a "defaulted
+ state". Upon reaching a defaulted state, a Bison-generated parser
+ does not bother to invoke `yylex' to fetch the next token before
+ performing the reduction. In other words, whether default
+ reductions are enabled in consistent states determines how soon a
+ Bison-generated parser invokes `yylex' for a token: immediately
+ when it _reaches_ that token in the input or when it eventually
+ _needs_ that token as a lookahead to determine the next parser
+ action. Traditionally, default reductions are enabled, and so the
+ parser exhibits the latter behavior.
+
+ The presence of defaulted states is an important consideration when
+ designing `yylex' and the grammar file. That is, if the behavior
+ of `yylex' can influence or be influenced by the semantic actions
+ associated with the reductions in defaulted states, then the delay
+ of the next `yylex' invocation until after those reductions is
+ significant. For example, the semantic actions might pop a scope
+ stack that `yylex' uses to determine what token to return. Thus,
+ the delay might be necessary to ensure that `yylex' does not look
+ up the next token in a scope that should already be considered
+ closed.
+
+ * Delayed syntax error detection.
+
+ When the parser fetches a new token by invoking `yylex', it checks
+ whether there is an action for that token in the current parser
+ state. The parser detects a syntax error if and only if either
+ (1) there is no action for that token or (2) the action for that
+ token is the error action (due to the use of `%nonassoc').
+ However, if there is a default reduction in that state (which
+ might or might not be a defaulted state), then it is impossible
+ for condition 1 to exist. That is, all tokens have an action.
+ Thus, the parser sometimes fails to detect the syntax error until
+ it reaches a later state.
+
+ While default reductions never cause the parser to accept
+ syntactically incorrect sentences, the delay of syntax error
+ detection can have unexpected effects on the behavior of the
+ parser. However, the delay can be caused anyway by parser state
+ merging and the use of `%nonassoc', and it can be fixed by another
+ Bison feature, LAC. We discuss the effects of delayed syntax
+ error detection and LAC more in the next section (*note LAC::).
+
+ For canonical LR, the only default reduction that Bison enables by
+default is the accept action, which appears only in the accepting
+state, which has no other action and is thus a defaulted state.
+However, the default accept action does not delay any `yylex'
+invocation or syntax error detection because the accept action ends the
+parse.
+
+ For LALR and IELR, Bison enables default reductions in nearly all
+states by default. There are only two exceptions. First, states that
+have a shift action on the `error' token do not have default reductions
+because delayed syntax error detection could then prevent the `error'
+token from ever being shifted in that state. However, parser state
+merging can cause the same effect anyway, and LAC fixes it in both
+cases, so future versions of Bison might drop this exception when LAC
+is activated. Second, GLR parsers do not record the default reduction
+as the action on a lookahead token for which there is a conflict. The
+correct action in this case is to split the parse instead.
+
+ To adjust which states have default reductions enabled, use the
+`%define lr.default-reductions' directive.
+
+ -- Directive: %define lr.default-reductions WHERE
+ Specify the kind of states that are permitted to contain default
+ reductions. The accepted values of WHERE are:
+ * `most' (default for LALR and IELR)
+
+ * `consistent'
+
+ * `accepting' (default for canonical LR)
+
+ (The ability to specify where default reductions are permitted is
+ experimental. More user feedback will help to stabilize it.)
+

+
+5.8.3 LAC
+---------
+
+Canonical LR, IELR, and LALR can suffer from a couple of problems upon
+encountering a syntax error. First, the parser might perform additional
+parser stack reductions before discovering the syntax error. Such
+reductions can perform user semantic actions that are unexpected because
+they are based on an invalid token, and they cause error recovery to
+begin in a different syntactic context than the one in which the
+invalid token was encountered. Second, when verbose error messages are
+enabled (*note Error Reporting::), the expected token list in the
+syntax error message can both contain invalid tokens and omit valid
+tokens.
+
+ The culprits for the above problems are `%nonassoc', default
+reductions in inconsistent states (*note Default Reductions::), and
+parser state merging. Because IELR and LALR merge parser states, they
+suffer the most. Canonical LR can suffer only if `%nonassoc' is used
+or if default reductions are enabled for inconsistent states.
+
+ LAC (Lookahead Correction) is a new mechanism within the parsing
+algorithm that solves these problems for canonical LR, IELR, and LALR
+without sacrificing `%nonassoc', default reductions, or state merging.
+You can enable LAC with the `%define parse.lac' directive.
+
+ -- Directive: %define parse.lac VALUE
+ Enable LAC to improve syntax error handling.
+ * `none' (default)
+
+ * `full'
+ (This feature is experimental. More user feedback will help to
+ stabilize it. Moreover, it is currently only available for
+ deterministic parsers in C.)
+
+ Conceptually, the LAC mechanism is straight-forward. Whenever the
+parser fetches a new token from the scanner so that it can determine
+the next parser action, it immediately suspends normal parsing and
+performs an exploratory parse using a temporary copy of the normal
+parser state stack. During this exploratory parse, the parser does not
+perform user semantic actions. If the exploratory parse reaches a
+shift action, normal parsing then resumes on the normal parser stacks.
+If the exploratory parse reaches an error instead, the parser reports a
+syntax error. If verbose syntax error messages are enabled, the parser
+must then discover the list of expected tokens, so it performs a
+separate exploratory parse for each token in the grammar.
+
+ There is one subtlety about the use of LAC. That is, when in a
+consistent parser state with a default reduction, the parser will not
+attempt to fetch a token from the scanner because no lookahead is
+needed to determine the next parser action. Thus, whether default
+reductions are enabled in consistent states (*note Default
+Reductions::) affects how soon the parser detects a syntax error:
+immediately when it _reaches_ an erroneous token or when it eventually
+_needs_ that token as a lookahead to determine the next parser action.
+The latter behavior is probably more intuitive, so Bison currently
+provides no way to achieve the former behavior while default reductions
+are enabled in consistent states.
+
+ Thus, when LAC is in use, for some fixed decision of whether to
+enable default reductions in consistent states, canonical LR and IELR
+behave almost exactly the same for both syntactically acceptable and
+syntactically unacceptable input. While LALR still does not support
+the full language-recognition power of canonical LR and IELR, LAC at
+least enables LALR's syntax error handling to correctly reflect LALR's
+language-recognition power.
+
+ There are a few caveats to consider when using LAC:
+
+ * Infinite parsing loops.
+
+ IELR plus LAC does have one shortcoming relative to canonical LR.
+ Some parsers generated by Bison can loop infinitely. LAC does not
+ fix infinite parsing loops that occur between encountering a
+ syntax error and detecting it, but enabling canonical LR or
+ disabling default reductions sometimes does.
+
+ * Verbose error message limitations.
+
+ Because of internationalization considerations, Bison-generated
+ parsers limit the size of the expected token list they are willing
+ to report in a verbose syntax error message. If the number of
+ expected tokens exceeds that limit, the list is simply dropped
+ from the message. Enabling LAC can increase the size of the list
+ and thus cause the parser to drop it. Of course, dropping the
+ list is better than reporting an incorrect list.
+
+ * Performance.
+
+ Because LAC requires many parse actions to be performed twice, it
+ can have a performance penalty. However, not all parse actions
+ must be performed twice. Specifically, during a series of default
+ reductions in consistent states and shift actions, the parser
+ never has to initiate an exploratory parse. Moreover, the most
+ time-consuming tasks in a parse are often the file I/O, the
+ lexical analysis performed by the scanner, and the user's semantic
+ actions, but none of these are performed during the exploratory
+ parse. Finally, the base of the temporary stack used during an
+ exploratory parse is a pointer into the normal parser state stack
+ so that the stack is never physically copied. In our experience,
+ the performance penalty of LAC has proved insignificant for
+ practical grammars.
+
+ While the LAC algorithm shares techniques that have been recognized
+in the parser community for years, for the publication that introduces
+LAC, *note Denny 2010 May: Bibliography.
+
+\1f
+File: bison.info, Node: Unreachable States, Prev: LAC, Up: Tuning LR
+
+5.8.4 Unreachable States
+------------------------
+
+If there exists no sequence of transitions from the parser's start
+state to some state S, then Bison considers S to be an "unreachable
+state". A state can become unreachable during conflict resolution if
+Bison disables a shift action leading to it from a predecessor state.
+
+ By default, Bison removes unreachable states from the parser after
+conflict resolution because they are useless in the generated parser.
+However, keeping unreachable states is sometimes useful when trying to
+understand the relationship between the parser and the grammar.
+
+ -- Directive: %define lr.keep-unreachable-states VALUE
+ Request that Bison allow unreachable states to remain in the
+ parser tables. VALUE must be a Boolean. The default is `false'.
+
+ There are a few caveats to consider:
+
+ * Missing or extraneous warnings.
+
+ Unreachable states may contain conflicts and may use rules not
+ used in any other state. Thus, keeping unreachable states may
+ induce warnings that are irrelevant to your parser's behavior, and
+ it may eliminate warnings that are relevant. Of course, the
+ change in warnings may actually be relevant to a parser table
+ analysis that wants to keep unreachable states, so this behavior
+ will likely remain in future Bison releases.
+
+ * Other useless states.
+
+ While Bison is able to remove unreachable states, it is not
+ guaranteed to remove other kinds of useless states. Specifically,
+ when Bison disables reduce actions during conflict resolution,
+ some goto actions may become useless, and thus some additional
+ states may become useless. If Bison were to compute which goto
+ actions were useless and then disable those actions, it could
+ identify such states as unreachable and then remove those states.
+ However, Bison does not compute which goto actions are useless.

+
+5.9 Generalized LR (GLR) Parsing
+================================
+
+Bison produces _deterministic_ parsers that choose uniquely when to
+reduce and which reduction to apply based on a summary of the preceding
+input and on one extra token of lookahead. As a result, normal Bison
+handles a proper subset of the family of context-free languages.
+Ambiguous grammars, since they have strings with more than one possible
+sequence of reductions cannot have deterministic parsers in this sense.
+The same is true of languages that require more than one symbol of
+lookahead, since the parser lacks the information necessary to make a
+decision at the point it must be made in a shift-reduce parser.
+Finally, as previously mentioned (*note Mysterious Conflicts::), there
+are languages where Bison's default choice of how to summarize the
+input seen so far loses necessary information.
+
+ When you use the `%glr-parser' declaration in your grammar file,
+Bison generates a parser that uses a different algorithm, called
+Generalized LR (or GLR). A Bison GLR parser uses the same basic
+algorithm for parsing as an ordinary Bison parser, but behaves
+differently in cases where there is a shift-reduce conflict that has not
+been resolved by precedence rules (*note Precedence::) or a
+reduce-reduce conflict. When a GLR parser encounters such a situation,
+it effectively _splits_ into a several parsers, one for each possible
+shift or reduction. These parsers then proceed as usual, consuming
+tokens in lock-step. Some of the stacks may encounter other conflicts
+and split further, with the result that instead of a sequence of states,
+a Bison GLR parsing stack is what is in effect a tree of states.
+
+ In effect, each stack represents a guess as to what the proper parse
+is. Additional input may indicate that a guess was wrong, in which case
+the appropriate stack silently disappears. Otherwise, the semantics
+actions generated in each stack are saved, rather than being executed
+immediately. When a stack disappears, its saved semantic actions never
+get executed. When a reduction causes two stacks to become equivalent,
+their sets of semantic actions are both saved with the state that
+results from the reduction. We say that two stacks are equivalent when
+they both represent the same sequence of states, and each pair of
+corresponding states represents a grammar symbol that produces the same
+segment of the input token stream.
+
+ Whenever the parser makes a transition from having multiple states
+to having one, it reverts to the normal deterministic parsing
+algorithm, after resolving and executing the saved-up actions. At this
+transition, some of the states on the stack will have semantic values
+that are sets (actually multisets) of possible actions. The parser
+tries to pick one of the actions by first finding one whose rule has
+the highest dynamic precedence, as set by the `%dprec' declaration.
+Otherwise, if the alternative actions are not ordered by precedence,
+but there the same merging function is declared for both rules by the
+`%merge' declaration, Bison resolves and evaluates both and then calls
+the merge function on the result. Otherwise, it reports an ambiguity.
+
+ It is possible to use a data structure for the GLR parsing tree that
+permits the processing of any LR(1) grammar in linear time (in the size
+of the input), any unambiguous (not necessarily LR(1)) grammar in
+quadratic worst-case time, and any general (possibly ambiguous)
+context-free grammar in cubic worst-case time. However, Bison currently
+uses a simpler data structure that requires time proportional to the
+length of the input times the maximum number of stacks required for any
+prefix of the input. Thus, really ambiguous or nondeterministic
+grammars can require exponential time and space to process. Such badly
+behaving examples, however, are not generally of practical interest.
+Usually, nondeterminism in a grammar is local--the parser is "in doubt"
+only for a few tokens at a time. Therefore, the current data structure
+should generally be adequate. On LR(1) portions of a grammar, in
+particular, it is only slightly slower than with the deterministic
+LR(1) Bison parser.
+
+ For a more detailed exposition of GLR parsers, *note Scott 2000:

+
+5.10 Memory Management, and How to Avoid Memory Exhaustion
+==========================================================
+
+The Bison parser stack can run out of memory if too many tokens are
+shifted and not reduced. When this happens, the parser function
+`yyparse' calls `yyerror' and then returns 2.
+
+ Because Bison parsers have growing stacks, hitting the upper limit
+usually results from using a right recursion instead of a left
+recursion, see *note Recursive Rules: Recursion.
+
+ By defining the macro `YYMAXDEPTH', you can control how deep the
+parser stack can become before memory is exhausted. Define the macro
+with a value that is an integer. This value is the maximum number of
+tokens that can be shifted (and not reduced) before overflow.
+
+ The stack space allowed is not necessarily allocated. If you
+specify a large value for `YYMAXDEPTH', the parser normally allocates a
+small stack at first, and then makes it bigger by stages as needed.
+This increasing allocation happens automatically and silently.
+Therefore, you do not need to make `YYMAXDEPTH' painfully small merely
+to save space for ordinary inputs that do not need much stack.
+
+ However, do not allow `YYMAXDEPTH' to be a value so large that
+arithmetic overflow could occur when calculating the size of the stack
+space. Also, do not allow `YYMAXDEPTH' to be less than `YYINITDEPTH'.
+
+ The default value of `YYMAXDEPTH', if you do not define it, is 10000.
+
+ You can control how much stack is allocated initially by defining the
+macro `YYINITDEPTH' to a positive integer. For the deterministic
+parser in C, this value must be a compile-time constant unless you are
+assuming C99 or some other target language or compiler that allows
+variable-length arrays. The default is 200.
+
+ Do not allow `YYINITDEPTH' to be greater than `YYMAXDEPTH'.
+
+ Because of semantic differences between C and C++, the deterministic
+parsers in C produced by Bison cannot grow when compiled by C++
+compilers. In this precise case (compiling a C parser as C++) you are
+suggested to grow `YYINITDEPTH'. The Bison maintainers hope to fix
+this deficiency in a future release.

+6 Error Recovery
+****************
+
+It is not usually acceptable to have a program terminate on a syntax
+error. For example, a compiler should recover sufficiently to parse the
+rest of the input file and check it for errors; a calculator should
+accept another expression.
+
+ In a simple interactive command parser where each input is one line,
+it may be sufficient to allow `yyparse' to return 1 on error and have
+the caller ignore the rest of the input line when that happens (and
+then call `yyparse' again). But this is inadequate for a compiler,
+because it forgets all the syntactic context leading up to the error.
+A syntax error deep within a function in the compiler input should not
+cause the compiler to treat the following line like the beginning of a
+source file.
+
+ You can define how to recover from a syntax error by writing rules to
+recognize the special token `error'. This is a terminal symbol that is
+always defined (you need not declare it) and reserved for error
+handling. The Bison parser generates an `error' token whenever a
+syntax error happens; if you have provided a rule to recognize this
+token in the current context, the parse can continue.
+
+ For example:
+
+ stmts:
+ /* empty string */
+ | stmts '\n'
+ | stmts exp '\n'
+ | stmts error '\n'
+
+ The fourth rule in this example says that an error followed by a
+newline makes a valid addition to any `stmts'.
+
+ What happens if a syntax error occurs in the middle of an `exp'? The
+error recovery rule, interpreted strictly, applies to the precise
+sequence of a `stmts', an `error' and a newline. If an error occurs in
+the middle of an `exp', there will probably be some additional tokens
+and subexpressions on the stack after the last `stmts', and there will
+be tokens to read before the next newline. So the rule is not
+applicable in the ordinary way.
+
+ But Bison can force the situation to fit the rule, by discarding
+part of the semantic context and part of the input. First it discards
+states and objects from the stack until it gets back to a state in
+which the `error' token is acceptable. (This means that the
+subexpressions already parsed are discarded, back to the last complete
+`stmts'.) At this point the `error' token can be shifted. Then, if
+the old lookahead token is not acceptable to be shifted next, the
+parser reads tokens and discards them until it finds a token which is
+acceptable. In this example, Bison reads and discards input until the
+next newline so that the fourth rule can apply. Note that discarded
+symbols are possible sources of memory leaks, see *note Freeing
+Discarded Symbols: Destructor Decl, for a means to reclaim this memory.
+
+ The choice of error rules in the grammar is a choice of strategies
+for error recovery. A simple and useful strategy is simply to skip the
+rest of the current input line or current statement if an error is
+detected:
+
+ stmt: error ';' /* On error, skip until ';' is read. */
+
+ It is also useful to recover to the matching close-delimiter of an
+opening-delimiter that has already been parsed. Otherwise the
+close-delimiter will probably appear to be unmatched, and generate
+another, spurious error message:
+
+ primary:
+ '(' expr ')'
+ | '(' error ')'
+ ...
+ ;
+
+ Error recovery strategies are necessarily guesses. When they guess
+wrong, one syntax error often leads to another. In the above example,
+the error recovery rule guesses that an error is due to bad input
+within one `stmt'. Suppose that instead a spurious semicolon is
+inserted in the middle of a valid `stmt'. After the error recovery
+rule recovers from the first error, another syntax error will be found
+straightaway, since the text following the spurious semicolon is also
+an invalid `stmt'.
+
+ To prevent an outpouring of error messages, the parser will output
+no error message for another syntax error that happens shortly after
+the first; only after three consecutive input tokens have been
+successfully shifted will error messages resume.
+
+ Note that rules which accept the `error' token may have actions, just
+as any other rules can.
+
+ You can make error messages resume immediately by using the macro
+`yyerrok' in an action. If you do this in the error rule's action, no
+error messages will be suppressed. This macro requires no arguments;
+`yyerrok;' is a valid C statement.
+
+ The previous lookahead token is reanalyzed immediately after an
+error. If this is unacceptable, then the macro `yyclearin' may be used
+to clear this token. Write the statement `yyclearin;' in the error
+rule's action. *Note Special Features for Use in Actions: Action
+Features.
+
+ For example, suppose that on a syntax error, an error handling
+routine is called that advances the input stream to some point where
+parsing should once again commence. The next symbol returned by the
+lexical scanner is probably correct. The previous lookahead token
+ought to be discarded with `yyclearin;'.
+
+ The expression `YYRECOVERING ()' yields 1 when the parser is
+recovering from a syntax error, and 0 otherwise. Syntax error
+diagnostics are suppressed while recovering from a syntax error.

+7 Handling Context Dependencies
+*******************************
+
+The Bison paradigm is to parse tokens first, then group them into larger
+syntactic units. In many languages, the meaning of a token is affected
+by its context. Although this violates the Bison paradigm, certain
+techniques (known as "kludges") may enable you to write Bison parsers
+for such languages.
+
+* Menu:
+
+* Semantic Tokens:: Token parsing can depend on the semantic context.
+* Lexical Tie-ins:: Token parsing can depend on the syntactic context.
+* Tie-in Recovery:: Lexical tie-ins have implications for how
+ error recovery rules must be written.
+
+ (Actually, "kludge" means any technique that gets its job done but is
+neither clean nor robust.)
+
+\1f
+File: bison.info, Node: Semantic Tokens, Next: Lexical Tie-ins, Up: Context Dependency
+
+7.1 Semantic Info in Token Types
+================================
+
+The C language has a context dependency: the way an identifier is used
+depends on what its current meaning is. For example, consider this:
+
+ foo (x);
+
+ This looks like a function call statement, but if `foo' is a typedef
+name, then this is actually a declaration of `x'. How can a Bison
+parser for C decide how to parse this input?
+
+ The method used in GNU C is to have two different token types,
+`IDENTIFIER' and `TYPENAME'. When `yylex' finds an identifier, it
+looks up the current declaration of the identifier in order to decide
+which token type to return: `TYPENAME' if the identifier is declared as
+a typedef, `IDENTIFIER' otherwise.
+
+ The grammar rules can then express the context dependency by the
+choice of token type to recognize. `IDENTIFIER' is accepted as an
+expression, but `TYPENAME' is not. `TYPENAME' can start a declaration,
+but `IDENTIFIER' cannot. In contexts where the meaning of the
+identifier is _not_ significant, such as in declarations that can
+shadow a typedef name, either `TYPENAME' or `IDENTIFIER' is
+accepted--there is one rule for each of the two token types.
+
+ This technique is simple to use if the decision of which kinds of
+identifiers to allow is made at a place close to where the identifier is
+parsed. But in C this is not always so: C allows a declaration to
+redeclare a typedef name provided an explicit type has been specified
+earlier:
+
+ typedef int foo, bar;
+ int baz (void)
+ {
+ static bar (bar); /* redeclare `bar' as static variable */
+ extern foo foo (foo); /* redeclare `foo' as function */
+ return foo (bar);
+ }
+
+ Unfortunately, the name being declared is separated from the
+declaration construct itself by a complicated syntactic structure--the
+"declarator".
+
+ As a result, part of the Bison parser for C needs to be duplicated,
+with all the nonterminal names changed: once for parsing a declaration
+in which a typedef name can be redefined, and once for parsing a
+declaration in which that can't be done. Here is a part of the
+duplication, with actions omitted for brevity:
+
+ initdcl:
+ declarator maybeasm '=' init
+ | declarator maybeasm
+ ;
+
+ notype_initdcl:
+ notype_declarator maybeasm '=' init
+ | notype_declarator maybeasm
+ ;
+
+Here `initdcl' can redeclare a typedef name, but `notype_initdcl'
+cannot. The distinction between `declarator' and `notype_declarator'
+is the same sort of thing.
+
+ There is some similarity between this technique and a lexical tie-in
+(described next), in that information which alters the lexical analysis
+is changed during parsing by other parts of the program. The
+difference is here the information is global, and is used for other
+purposes in the program. A true lexical tie-in has a special-purpose
+flag controlled by the syntactic context.
+
+\1f
+File: bison.info, Node: Lexical Tie-ins, Next: Tie-in Recovery, Prev: Semantic Tokens, Up: Context Dependency
+
+7.2 Lexical Tie-ins
+===================
+
+One way to handle context-dependency is the "lexical tie-in": a flag
+which is set by Bison actions, whose purpose is to alter the way tokens
+are parsed.
+
+ For example, suppose we have a language vaguely like C, but with a
+special construct `hex (HEX-EXPR)'. After the keyword `hex' comes an
+expression in parentheses in which all integers are hexadecimal. In
+particular, the token `a1b' must be treated as an integer rather than
+as an identifier if it appears in that context. Here is how you can do
+it:
+
+ %{
+ int hexflag;
+ int yylex (void);
+ void yyerror (char const *);
+ %}
+ %%
+ ...
+ expr:
+ IDENTIFIER
+ | constant
+ | HEX '(' { hexflag = 1; }
+ expr ')' { hexflag = 0; $$ = $4; }
+ | expr '+' expr { $$ = make_sum ($1, $3); }
+ ...
+ ;
+
+ constant:
+ INTEGER
+ | STRING
+ ;
+
+Here we assume that `yylex' looks at the value of `hexflag'; when it is
+nonzero, all integers are parsed in hexadecimal, and tokens starting
+with letters are parsed as integers if possible.
+
+ The declaration of `hexflag' shown in the prologue of the grammar
+file is needed to make it accessible to the actions (*note The
+Prologue: Prologue.). You must also write the code in `yylex' to obey
+the flag.
+
+\1f
+File: bison.info, Node: Tie-in Recovery, Prev: Lexical Tie-ins, Up: Context Dependency
+
+7.3 Lexical Tie-ins and Error Recovery
+======================================
+
+Lexical tie-ins make strict demands on any error recovery rules you
+have. *Note Error Recovery::.
+
+ The reason for this is that the purpose of an error recovery rule is
+to abort the parsing of one construct and resume in some larger
+construct. For example, in C-like languages, a typical error recovery
+rule is to skip tokens until the next semicolon, and then start a new
+statement, like this:
+
+ stmt:
+ expr ';'
+ | IF '(' expr ')' stmt { ... }
+ ...
+ | error ';' { hexflag = 0; }
+ ;
+
+ If there is a syntax error in the middle of a `hex (EXPR)'
+construct, this error rule will apply, and then the action for the
+completed `hex (EXPR)' will never run. So `hexflag' would remain set
+for the entire rest of the input, or until the next `hex' keyword,
+causing identifiers to be misinterpreted as integers.
+
+ To avoid this problem the error recovery rule itself clears
+`hexflag'.
+
+ There may also be an error recovery rule that works within
+expressions. For example, there could be a rule which applies within
+parentheses and skips to the close-parenthesis:
+
+ expr:
+ ...
+ | '(' expr ')' { $$ = $2; }
+ | '(' error ')'
+ ...
+
+ If this rule acts within the `hex' construct, it is not going to
+abort that construct (since it applies to an inner level of parentheses
+within the construct). Therefore, it should not clear the flag: the
+rest of the `hex' construct should be parsed with the flag still in
+effect.
+
+ What if there is an error recovery rule which might abort out of the
+`hex' construct or might not, depending on circumstances? There is no
+way you can write the action to determine whether a `hex' construct is
+being aborted or not. So if you are using a lexical tie-in, you had
+better make sure your error recovery rules are not of this kind. Each
+rule must be such that you can be sure that it always will, or always
+won't, have to clear the flag.

+8 Debugging Your Parser
+***********************
+
+Developing a parser can be a challenge, especially if you don't
+understand the algorithm (*note The Bison Parser Algorithm:
+Algorithm.). This chapter explains how to generate and read the
+detailed description of the automaton, and how to enable and understand
+the parser run-time traces.
+
+* Menu:
+
+* Understanding:: Understanding the structure of your parser.
+* Tracing:: Tracing the execution of your parser.
+
+\1f
+File: bison.info, Node: Understanding, Next: Tracing, Up: Debugging
+
+8.1 Understanding Your Parser
+=============================
+
+As documented elsewhere (*note The Bison Parser Algorithm: Algorithm.)
+Bison parsers are "shift/reduce automata". In some cases (much more
+frequent than one would hope), looking at this automaton is required to
+tune or simply fix a parser. Bison provides two different
+representation of it, either textually or graphically (as a DOT file).
+
+ The textual file is generated when the options `--report' or
+`--verbose' are specified, see *note Invoking Bison: Invocation. Its
+name is made by removing `.tab.c' or `.c' from the parser
+implementation file name, and adding `.output' instead. Therefore, if
+the grammar file is `foo.y', then the parser implementation file is
+called `foo.tab.c' by default. As a consequence, the verbose output
+file is called `foo.output'.
+
+ The following grammar file, `calc.y', will be used in the sequel:
+
+ %token NUM STR
+ %left '+' '-'
+ %left '*'
+ %%
+ exp:
+ exp '+' exp
+ | exp '-' exp
+ | exp '*' exp
+ | exp '/' exp
+ | NUM
+ ;
+ useless: STR;
+ %%
+
+ `bison' reports:
+
+ calc.y: warning: 1 nonterminal useless in grammar
+ calc.y: warning: 1 rule useless in grammar
+ calc.y:11.1-7: warning: nonterminal useless in grammar: useless
+ calc.y:11.10-12: warning: rule useless in grammar: useless: STR
+ calc.y: conflicts: 7 shift/reduce
+
+ When given `--report=state', in addition to `calc.tab.c', it creates
+a file `calc.output' with contents detailed below. The order of the
+output and the exact presentation might vary, but the interpretation is
+the same.
+
+The first section reports useless tokens, nonterminals and rules.
+Useless nonterminals and rules are removed in order to produce a
+smaller parser, but useless tokens are preserved, since they might be
+used by the scanner (note the difference between "useless" and "unused"
+below):
+
+ Nonterminals useless in grammar
+ useless
+
+ Terminals unused in grammar
+ STR
+
+ Rules useless in grammar
+ 6 useless: STR
+
+The next section lists states that still have conflicts.
+
+ State 8 conflicts: 1 shift/reduce
+ State 9 conflicts: 1 shift/reduce
+ State 10 conflicts: 1 shift/reduce
+ State 11 conflicts: 4 shift/reduce
+
+Then Bison reproduces the exact grammar it used:
+
+ Grammar
+
+ 0 $accept: exp $end
+
+ 1 exp: exp '+' exp
+ 2 | exp '-' exp
+ 3 | exp '*' exp
+ 4 | exp '/' exp
+ 5 | NUM
+
+and reports the uses of the symbols:
+
+ Terminals, with rules where they appear
+
+ $end (0) 0
+ '*' (42) 3
+ '+' (43) 1
+ '-' (45) 2
+ '/' (47) 4
+ error (256)
+ NUM (258) 5
+ STR (259)
+
+ Nonterminals, with rules where they appear
+
+ $accept (9)
+ on left: 0
+ exp (10)
+ on left: 1 2 3 4 5, on right: 0 1 2 3 4
+
+Bison then proceeds onto the automaton itself, describing each state
+with its set of "items", also known as "pointed rules". Each item is a
+production rule together with a point (`.') marking the location of the
+input cursor.
+
+ state 0
+
+ 0 $accept: . exp $end
+
+ NUM shift, and go to state 1
+
+ exp go to state 2
+
+ This reads as follows: "state 0 corresponds to being at the very
+beginning of the parsing, in the initial rule, right before the start
+symbol (here, `exp'). When the parser returns to this state right
+after having reduced a rule that produced an `exp', the control flow
+jumps to state 2. If there is no such transition on a nonterminal
+symbol, and the lookahead is a `NUM', then this token is shifted onto
+the parse stack, and the control flow jumps to state 1. Any other
+lookahead triggers a syntax error."
+
+ Even though the only active rule in state 0 seems to be rule 0, the
+report lists `NUM' as a lookahead token because `NUM' can be at the
+beginning of any rule deriving an `exp'. By default Bison reports the
+so-called "core" or "kernel" of the item set, but if you want to see
+more detail you can invoke `bison' with `--report=itemset' to list the
+derived items as well:
+
+ state 0
+
+ 0 $accept: . exp $end
+ 1 exp: . exp '+' exp
+ 2 | . exp '-' exp
+ 3 | . exp '*' exp
+ 4 | . exp '/' exp
+ 5 | . NUM
+
+ NUM shift, and go to state 1
+
+ exp go to state 2
+
+In the state 1...
+
+ state 1
+
+ 5 exp: NUM .
+
+ $default reduce using rule 5 (exp)
+
+the rule 5, `exp: NUM;', is completed. Whatever the lookahead token
+(`$default'), the parser will reduce it. If it was coming from state
+0, then, after this reduction it will return to state 0, and will jump
+to state 2 (`exp: go to state 2').
+
+ state 2
+
+ 0 $accept: exp . $end
+ 1 exp: exp . '+' exp
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ $end shift, and go to state 3
+ '+' shift, and go to state 4
+ '-' shift, and go to state 5
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+In state 2, the automaton can only shift a symbol. For instance,
+because of the item `exp: exp . '+' exp', if the lookahead is `+' it is
+shifted onto the parse stack, and the automaton jumps to state 4,
+corresponding to the item `exp: exp '+' . exp'. Since there is no
+default action, any lookahead not listed triggers a syntax error.
+
+ The state 3 is named the "final state", or the "accepting state":
+
+ state 3
+
+ 0 $accept: exp $end .
+
+ $default accept
+
+the initial rule is completed (the start symbol and the end-of-input
+were read), the parsing exits successfully.
+
+ The interpretation of states 4 to 7 is straightforward, and is left
+to the reader.
+
+ state 4
+
+ 1 exp: exp '+' . exp
+
+ NUM shift, and go to state 1
+
+ exp go to state 8
+
+
+ state 5
+
+ 2 exp: exp '-' . exp
+
+ NUM shift, and go to state 1
+
+ exp go to state 9
+
+
+ state 6
+
+ 3 exp: exp '*' . exp
+
+ NUM shift, and go to state 1
+
+ exp go to state 10
+
+
+ state 7
+
+ 4 exp: exp '/' . exp
+
+ NUM shift, and go to state 1
+
+ exp go to state 11
+
+ As was announced in beginning of the report, `State 8 conflicts: 1
+shift/reduce':
+
+ state 8
+
+ 1 exp: exp . '+' exp
+ 1 | exp '+' exp .
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+ '/' [reduce using rule 1 (exp)]
+ $default reduce using rule 1 (exp)
+
+ Indeed, there are two actions associated to the lookahead `/':
+either shifting (and going to state 7), or reducing rule 1. The
+conflict means that either the grammar is ambiguous, or the parser lacks
+information to make the right decision. Indeed the grammar is
+ambiguous, as, since we did not specify the precedence of `/', the
+sentence `NUM + NUM / NUM' can be parsed as `NUM + (NUM / NUM)', which
+corresponds to shifting `/', or as `(NUM + NUM) / NUM', which
+corresponds to reducing rule 1.
+
+ Because in deterministic parsing a single decision can be made, Bison
+arbitrarily chose to disable the reduction, see *note Shift/Reduce
+Conflicts: Shift/Reduce. Discarded actions are reported between square
+brackets.
+
+ Note that all the previous states had a single possible action:
+either shifting the next token and going to the corresponding state, or
+reducing a single rule. In the other cases, i.e., when shifting _and_
+reducing is possible or when _several_ reductions are possible, the
+lookahead is required to select the action. State 8 is one such state:
+if the lookahead is `*' or `/' then the action is shifting, otherwise
+the action is reducing rule 1. In other words, the first two items,
+corresponding to rule 1, are not eligible when the lookahead token is
+`*', since we specified that `*' has higher precedence than `+'. More
+generally, some items are eligible only with some set of possible
+lookahead tokens. When run with `--report=lookahead', Bison specifies
+these lookahead tokens:
+
+ state 8
+
+ 1 exp: exp . '+' exp
+ 1 | exp '+' exp . [$end, '+', '-', '/']
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+ '/' [reduce using rule 1 (exp)]
+ $default reduce using rule 1 (exp)
+
+ Note however that while `NUM + NUM / NUM' is ambiguous (which
+results in the conflicts on `/'), `NUM + NUM * NUM' is not: the
+conflict was solved thanks to associativity and precedence directives.
+If invoked with `--report=solved', Bison includes information about the
+solved conflicts in the report:
+
+ Conflict between rule 1 and token '+' resolved as reduce (%left '+').
+ Conflict between rule 1 and token '-' resolved as reduce (%left '-').
+ Conflict between rule 1 and token '*' resolved as shift ('+' < '*').
+
+ The remaining states are similar:
+
+ state 9
+
+ 1 exp: exp . '+' exp
+ 2 | exp . '-' exp
+ 2 | exp '-' exp .
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+ '/' [reduce using rule 2 (exp)]
+ $default reduce using rule 2 (exp)
+
+ state 10
+
+ 1 exp: exp . '+' exp
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 3 | exp '*' exp .
+ 4 | exp . '/' exp
+
+ '/' shift, and go to state 7
+
+ '/' [reduce using rule 3 (exp)]
+ $default reduce using rule 3 (exp)
+
+ state 11
+
+ 1 exp: exp . '+' exp
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+ 4 | exp '/' exp .
+
+ '+' shift, and go to state 4
+ '-' shift, and go to state 5
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+ '+' [reduce using rule 4 (exp)]
+ '-' [reduce using rule 4 (exp)]
+ '*' [reduce using rule 4 (exp)]
+ '/' [reduce using rule 4 (exp)]
+ $default reduce using rule 4 (exp)
+
+Observe that state 11 contains conflicts not only due to the lack of
+precedence of `/' with respect to `+', `-', and `*', but also because
+the associativity of `/' is not specified.

+8.2 Tracing Your Parser
+=======================
+
+When a Bison grammar compiles properly but parses "incorrectly", the
+`yydebug' parser-trace feature helps figuring out why.
+
+* Menu:
+
+* Enabling Traces:: Activating run-time trace support
+* Mfcalc Traces:: Extending `mfcalc' to support traces
+* The YYPRINT Macro:: Obsolete interface for semantic value reports
+
+\1f
+File: bison.info, Node: Enabling Traces, Next: Mfcalc Traces, Up: Tracing
+
+8.2.1 Enabling Traces
+---------------------
+
+There are several means to enable compilation of trace facilities:
+
+the macro `YYDEBUG'
+ Define the macro `YYDEBUG' to a nonzero value when you compile the
+ parser. This is compliant with POSIX Yacc. You could use
+ `-DYYDEBUG=1' as a compiler option or you could put `#define
+ YYDEBUG 1' in the prologue of the grammar file (*note The
+ Prologue: Prologue.).
+
+ If the `%define' variable `api.prefix' is used (*note Multiple
+ Parsers in the Same Program: Multiple Parsers.), for instance
+ `%define api.prefix x', then if `CDEBUG' is defined, its value
+ controls the tracing feature (enabled iff nonzero); otherwise
+ tracing is enabled iff `YYDEBUG' is nonzero.
+
+the option `-t' (POSIX Yacc compliant)
+the option `--debug' (Bison extension)
+ Use the `-t' option when you run Bison (*note Invoking Bison:
+ Invocation.). With `%define api.prefix c', it defines `CDEBUG' to
+ 1, otherwise it defines `YYDEBUG' to 1.
+
+the directive `%debug'
+ Add the `%debug' directive (*note Bison Declaration Summary: Decl
+ Summary.). This is a Bison extension, especially useful for
+ languages that don't use a preprocessor. Unless POSIX and Yacc
+ portability matter to you, this is the preferred solution.
+
+ We suggest that you always enable the debug option so that debugging
+is always possible.
+
+ The trace facility outputs messages with macro calls of the form
+`YYFPRINTF (stderr, FORMAT, ARGS)' where FORMAT and ARGS are the usual
+`printf' format and variadic arguments. If you define `YYDEBUG' to a
+nonzero value but do not define `YYFPRINTF', `<stdio.h>' is
+automatically included and `YYFPRINTF' is defined to `fprintf'.
+
+ Once you have compiled the program with trace facilities, the way to
+request a trace is to store a nonzero value in the variable `yydebug'.
+You can do this by making the C code do it (in `main', perhaps), or you
+can alter the value with a C debugger.
+
+ Each step taken by the parser when `yydebug' is nonzero produces a
+line or two of trace information, written on `stderr'. The trace
+messages tell you these things:
+
+ * Each time the parser calls `yylex', what kind of token was read.
+
+ * Each time a token is shifted, the depth and complete contents of
+ the state stack (*note Parser States::).
+
+ * Each time a rule is reduced, which rule it is, and the complete
+ contents of the state stack afterward.
+
+ To make sense of this information, it helps to refer to the automaton
+description file (*note Understanding Your Parser: Understanding.).
+This file shows the meaning of each state in terms of positions in
+various rules, and also what each state will do with each possible
+input token. As you read the successive trace messages, you can see
+that the parser is functioning according to its specification in the
+listing file. Eventually you will arrive at the place where something
+undesirable happens, and you will see which parts of the grammar are to
+blame.
+
+ The parser implementation file is a C/C++/Java program and you can
+use debuggers on it, but it's not easy to interpret what it is doing.
+The parser function is a finite-state machine interpreter, and aside

+
+8.2.2 Enabling Debug Traces for `mfcalc'
+----------------------------------------
+
+The debugging information normally gives the token type of each token
+read, but not its semantic value. The `%printer' directive allows
+specify how semantic values are reported, see *note Printing Semantic
+Values: Printer Decl. For backward compatibility, Yacc like C parsers
+may also use the `YYPRINT' (*note The `YYPRINT' Macro: The YYPRINT
+Macro.), but its use is discouraged.
+
+ As a demonstration of `%printer', consider the multi-function
+calculator, `mfcalc' (*note Multi-function Calc::). To enable run-time
+traces, and semantic value reports, insert the following directives in
+its prologue:
+
+ /* Generate the parser description file. */
+ %verbose
+ /* Enable run-time traces (yydebug). */
+ %define parse.trace
+
+ /* Formatting semantic values. */
+ %printer { fprintf (yyoutput, "%s", $$->name); } VAR;
+ %printer { fprintf (yyoutput, "%s()", $$->name); } FNCT;
+ %printer { fprintf (yyoutput, "%g", $$); } <val>;
+
+ The `%define' directive instructs Bison to generate run-time trace
+support. Then, activation of these traces is controlled at run-time by
+the `yydebug' variable, which is disabled by default. Because these
+traces will refer to the "states" of the parser, it is helpful to ask
+for the creation of a description of that parser; this is the purpose
+of (admittedly ill-named) `%verbose' directive.
+
+ The set of `%printer' directives demonstrates how to format the
+semantic value in the traces. Note that the specification can be done
+either on the symbol type (e.g., `VAR' or `FNCT'), or on the type tag:
+since `<val>' is the type for both `NUM' and `exp', this printer will
+be used for them.
+
+ Here is a sample of the information provided by run-time traces.
+The traces are sent onto standard error.
+

+ Starting parse
+ Entering state 0
+ Reducing stack by rule 1 (line 34):
+ -> $$ = nterm input ()
+ Stack now 0
+ Entering state 1
+
+This first batch shows a specific feature of this grammar: the first
+rule (which is in line 34 of `mfcalc.y' can be reduced without even
+having to look for the first token. The resulting left-hand symbol
+(`$$') is a valueless (`()') `input' non terminal (`nterm').
+
+ Then the parser calls the scanner.
+ Reading a token: Next token is token FNCT (sin())
+ Shifting token FNCT (sin())
+ Entering state 6
+
+That token (`token') is a function (`FNCT') whose value is `sin' as

+(`Shifting') that token, and others, until it can do something about it.

+
+8.2.3 The `YYPRINT' Macro
+-------------------------
+
+Before `%printer' support, semantic values could be displayed using the
+`YYPRINT' macro, which works only for terminal symbols and only with
+the `yacc.c' skeleton.
+
+ -- Macro: YYPRINT (STREAM, TOKEN, VALUE);
+ If you define `YYPRINT', it should take three arguments. The
+ parser will pass a standard I/O stream, the numeric code for the
+ token type, and the token value (from `yylval').
+
+ For `yacc.c' only. Obsoleted by `%printer'.
+
+ Here is an example of `YYPRINT' suitable for the multi-function
+calculator (*note Declarations for `mfcalc': Mfcalc Declarations.):
+
+ %{
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(File, Type, Value) \
+ print_token_value (File, Type, Value)
+ %}
+
+ ... %% ... %% ...
+
+ static void
+ print_token_value (FILE *file, int type, YYSTYPE value)
+ {
+ if (type == VAR)
+ fprintf (file, "%s", value.tptr->name);
+ else if (type == NUM)
+ fprintf (file, "%d", value.val);
+ }

+
+9 Invoking Bison
+****************
+
+The usual way to invoke Bison is as follows:
+
+ bison INFILE
+
+ Here INFILE is the grammar file name, which usually ends in `.y'.
+The parser implementation file's name is made by replacing the `.y'
+with `.tab.c' and removing any leading directory. Thus, the `bison
+foo.y' file name yields `foo.tab.c', and the `bison hack/foo.y' file
+name yields `foo.tab.c'. It's also possible, in case you are writing
+C++ code instead of C in your grammar file, to name it `foo.ypp' or
+`foo.y++'. Then, the output files will take an extension like the
+given one as input (respectively `foo.tab.cpp' and `foo.tab.c++'). This
+feature takes effect with all options that manipulate file names like
+`-o' or `-d'.
+
+ For example :
+
+ bison -d INFILE.YXX
+ will produce `infile.tab.cxx' and `infile.tab.hxx', and
+
+ bison -d -o OUTPUT.C++ INFILE.Y
+ will produce `output.c++' and `outfile.h++'.
+
+ For compatibility with POSIX, the standard Bison distribution also
+contains a shell script called `yacc' that invokes Bison with the `-y'
+option.
+
+* Menu:
+
+* Bison Options:: All the options described in detail,
+ in alphabetical order by short options.
+* Option Cross Key:: Alphabetical list of long options.
+* Yacc Library:: Yacc-compatible `yylex' and `main'.

+File: bison.info, Node: Bison Options, Next: Option Cross Key, Up: Invocation
+
+9.1 Bison Options
+=================
+
+Bison supports both traditional single-letter options and mnemonic long
+option names. Long option names are indicated with `--' instead of
+`-'. Abbreviations for option names are allowed as long as they are
+unique. When a long option takes an argument, like `--file-prefix',
+connect the option name and the argument with `='.
+
+ Here is a list of options that can be used with Bison, alphabetized
+by short option. It is followed by a cross key alphabetized by long
+option.
+
+Operations modes:
+`-h'
+`--help'
+ Print a summary of the command-line options to Bison and exit.
+
+`-V'
+`--version'
+ Print the version number of Bison and exit.
+
+`--print-localedir'
+ Print the name of the directory containing locale-dependent data.
+
+`--print-datadir'
+ Print the name of the directory containing skeletons and XSLT.
+
+`-y'
+`--yacc'
+ Act more like the traditional Yacc command. This can cause
+ different diagnostics to be generated, and may change behavior in
+ other minor ways. Most importantly, imitate Yacc's output file
+ name conventions, so that the parser implementation file is called
+ `y.tab.c', and the other outputs are called `y.output' and
+ `y.tab.h'. Also, if generating a deterministic parser in C,
+ generate `#define' statements in addition to an `enum' to associate
+ token numbers with token names. Thus, the following shell script
+ can substitute for Yacc, and the Bison distribution contains such
+ a script for compatibility with POSIX:
+
+ #! /bin/sh
+ bison -y "$@"
+
+ The `-y'/`--yacc' option is intended for use with traditional Yacc
+ grammars. If your grammar uses a Bison extension like
+ `%glr-parser', Bison might not be Yacc-compatible even if this
+ option is specified.
+
+`-W [CATEGORY]'
+`--warnings[=CATEGORY]'
+ Output warnings falling in CATEGORY. CATEGORY can be one of:
+ `midrule-values'
+ Warn about mid-rule values that are set but not used within
+ any of the actions of the parent rule. For example, warn
+ about unused `$2' in:
+
+ exp: '1' { $$ = 1; } '+' exp { $$ = $1 + $4; };
+
+ Also warn about mid-rule values that are used but not set.
+ For example, warn about unset `$$' in the mid-rule action in:
+
+ exp: '1' { $1 = 1; } '+' exp { $$ = $2 + $4; };
+
+ These warnings are not enabled by default since they
+ sometimes prove to be false alarms in existing grammars
+ employing the Yacc constructs `$0' or `$-N' (where N is some
+ positive integer).
+
+ `yacc'
+ Incompatibilities with POSIX Yacc.
+
+ `conflicts-sr'
+ `conflicts-rr'
+ S/R and R/R conflicts. These warnings are enabled by
+ default. However, if the `%expect' or `%expect-rr' directive
+ is specified, an unexpected number of conflicts is an error,
+ and an expected number of conflicts is not reported, so `-W'
+ and `--warning' then have no effect on the conflict report.
+
+ `other'
+ All warnings not categorized above. These warnings are
+ enabled by default.
+
+ This category is provided merely for the sake of
+ completeness. Future releases of Bison may move warnings
+ from this category to new, more specific categories.
+
+ `all'
+ All the warnings.
+
+ `none'
+ Turn off all the warnings.
+
+ `error'
+ Treat warnings as errors.
+
+ A category can be turned off by prefixing its name with `no-'. For
+ instance, `-Wno-yacc' will hide the warnings about POSIX Yacc
+ incompatibilities.
+
+Tuning the parser:
+
+`-t'
+`--debug'
+ In the parser implementation file, define the macro `YYDEBUG' to 1
+ if it is not already defined, so that the debugging facilities are
+ compiled. *Note Tracing Your Parser: Tracing.
+
+`-D NAME[=VALUE]'
+`--define=NAME[=VALUE]'
+`-F NAME[=VALUE]'
+`--force-define=NAME[=VALUE]'
+ Each of these is equivalent to `%define NAME "VALUE"' (*note
+ %define Summary::) except that Bison processes multiple
+ definitions for the same NAME as follows:
+
+ * Bison quietly ignores all command-line definitions for NAME
+ except the last.
+
+ * If that command-line definition is specified by a `-D' or
+ `--define', Bison reports an error for any `%define'
+ definition for NAME.
+
+ * If that command-line definition is specified by a `-F' or
+ `--force-define' instead, Bison quietly ignores all `%define'
+ definitions for NAME.
+
+ * Otherwise, Bison reports an error if there are multiple
+ `%define' definitions for NAME.
+
+ You should avoid using `-F' and `--force-define' in your make
+ files unless you are confident that it is safe to quietly ignore
+ any conflicting `%define' that may be added to the grammar file.
+
+`-L LANGUAGE'
+`--language=LANGUAGE'
+ Specify the programming language for the generated parser, as if
+ `%language' was specified (*note Bison Declaration Summary: Decl
+ Summary.). Currently supported languages include C, C++, and Java.
+ LANGUAGE is case-insensitive.
+
+ This option is experimental and its effect may be modified in
+ future releases.
+
+`--locations'
+ Pretend that `%locations' was specified. *Note Decl Summary::.
+
+`-p PREFIX'
+`--name-prefix=PREFIX'
+ Pretend that `%name-prefix "PREFIX"' was specified (*note Decl
+ Summary::). Obsoleted by `-Dapi.prefix=PREFIX'. *Note Multiple
+ Parsers in the Same Program: Multiple Parsers.
+
+`-l'
+`--no-lines'
+ Don't put any `#line' preprocessor commands in the parser
+ implementation file. Ordinarily Bison puts them in the parser
+ implementation file so that the C compiler and debuggers will
+ associate errors with your source file, the grammar file. This
+ option causes them to associate errors with the parser
+ implementation file, treating it as an independent source file in
+ its own right.
+
+`-S FILE'
+`--skeleton=FILE'
+ Specify the skeleton to use, similar to `%skeleton' (*note Bison
+ Declaration Summary: Decl Summary.).
+
+ If FILE does not contain a `/', FILE is the name of a skeleton
+ file in the Bison installation directory. If it does, FILE is an
+ absolute file name or a file name relative to the current working
+ directory. This is similar to how most shells resolve commands.
+
+`-k'
+`--token-table'
+ Pretend that `%token-table' was specified. *Note Decl Summary::.
+
+Adjust the output:
+
+`--defines[=FILE]'
+ Pretend that `%defines' was specified, i.e., write an extra output
+ file containing macro definitions for the token type names defined
+ in the grammar, as well as a few other declarations. *Note Decl
+ Summary::.
+
+`-d'
+ This is the same as `--defines' except `-d' does not accept a FILE
+ argument since POSIX Yacc requires that `-d' can be bundled with
+ other short options.
+
+`-b FILE-PREFIX'
+`--file-prefix=PREFIX'
+ Pretend that `%file-prefix' was specified, i.e., specify prefix to
+ use for all Bison output file names. *Note Decl Summary::.
+
+`-r THINGS'
+`--report=THINGS'
+ Write an extra output file containing verbose description of the
+ comma separated list of THINGS among:
+
+ `state'
+ Description of the grammar, conflicts (resolved and
+ unresolved), and parser's automaton.
+
+ `lookahead'
+ Implies `state' and augments the description of the automaton
+ with each rule's lookahead set.
+
+ `itemset'
+ Implies `state' and augments the description of the automaton
+ with the full set of items for each state, instead of its
+ core only.
+
+`--report-file=FILE'
+ Specify the FILE for the verbose description.
+
+`-v'
+`--verbose'
+ Pretend that `%verbose' was specified, i.e., write an extra output
+ file containing verbose descriptions of the grammar and parser.
+ *Note Decl Summary::.
+
+`-o FILE'
+`--output=FILE'
+ Specify the FILE for the parser implementation file.
+
+ The other output files' names are constructed from FILE as
+ described under the `-v' and `-d' options.
+
+`-g [FILE]'
+`--graph[=FILE]'
+ Output a graphical representation of the parser's automaton
+ computed by Bison, in Graphviz (http://www.graphviz.org/) DOT
+ (http://www.graphviz.org/doc/info/lang.html) format. `FILE' is
+ optional. If omitted and the grammar file is `foo.y', the output
+ file will be `foo.dot'.
+
+`-x [FILE]'
+`--xml[=FILE]'
+ Output an XML report of the parser's automaton computed by Bison.
+ `FILE' is optional. If omitted and the grammar file is `foo.y',

+9.3 Yacc Library
+================
+
+The Yacc library contains default implementations of the `yyerror' and
+`main' functions. These default implementations are normally not
+useful, but POSIX requires them. To use the Yacc library, link your
+program with the `-ly' option. Note that Bison's implementation of the
+Yacc library is distributed under the terms of the GNU General Public
+License (*note Copying::).
+
+ If you use the Yacc library's `yyerror' function, you should declare
+`yyerror' as follows:
+
+ int yyerror (char const *);
+
+ Bison ignores the `int' value returned by this `yyerror'. If you
+use the Yacc library's `main' function, your `yyparse' function should
+have the following type signature:
+
+ int yyparse (void);

+--------------------------
+
+The C++ deterministic parser is selected using the skeleton directive,
+`%skeleton "lalr1.cc"', or the synonymous command-line option
+`--skeleton=lalr1.cc'. *Note Decl Summary::.
+
+ When run, `bison' will create several entities in the `yy' namespace. Use
+the `%define namespace' directive to change the namespace name, see
+*note namespace: %define Summary. The various classes are generated in
+the following files:
+
+`position.hh'
+`location.hh'
+ The definition of the classes `position' and `location', used for
+ location tracking. *Note C++ Location Values::.
+
+`stack.hh'
+ An auxiliary class `stack' used by the parser.
+
+`FILE.hh'

+ (Assuming the extension of the grammar file was `.yy'.) The
+ declaration and implementation of the C++ parser class. The
+ basename and extension of these two files follow the same rules as
+ with regular C parsers (*note Invocation::).
+
+ The header is _mandatory_; you must either pass `-d'/`--defines'
+ to `bison', or use the `%defines' directive.
+
+ All these files are documented using Doxygen; run `doxygen' for a
+complete and accurate documentation.

+
+10.1.2 C++ Semantic Values
+--------------------------
+
+The `%union' directive works as for C, see *note The Collection of
+Value Types: Union Decl. In particular it produces a genuine
+`union'(1), which have a few specific features in C++.
+ - The type `YYSTYPE' is defined but its use is discouraged: rather
+ you should refer to the parser's encapsulated type
+ `yy::parser::semantic_type'.
+
+ - Non POD (Plain Old Data) types cannot be used. C++ forbids any
+ instance of classes with constructors in unions: only _pointers_
+ to such objects are allowed.
+
+ Because objects have to be stored via pointers, memory is not
+reclaimed automatically: using the `%destructor' directive is the only
+means to avoid leaks. *Note Freeing Discarded Symbols: Destructor Decl.
+
+ ---------- Footnotes ----------
+
+ (1) In the future techniques to allow complex types within
+pseudo-unions (similar to Boost variants) might be implemented to
+alleviate these issues.

+10.1.4 C++ Parser Interface
+---------------------------
+
+The output files `OUTPUT.hh' and `OUTPUT.cc' declare and define the
+parser class in the namespace `yy'. The class name defaults to
+`parser', but may be changed using `%define parser_class_name "NAME"'.
+The interface of this class is detailed below. It can be extended
+using the `%parse-param' feature: its semantics is slightly changed
+since it describes an additional member of the parser class, and an
+additional argument for its constructor.
+
+ -- Type of parser: semantic_type
+ -- Type of parser: location_type
+ The types for semantics value and locations.
+
+ -- Type of parser: token
+ A structure that contains (only) the `yytokentype' enumeration,
+ which defines the tokens. To refer to the token `FOO', use
+ `yy::parser::token::FOO'. The scanner can use `typedef
+ yy::parser::token token;' to "import" the token enumeration (*note
+ Calc++ Scanner::).
+
+ -- Method on parser: parser (TYPE1 ARG1, ...)
+ Build a new parser object. There are no arguments by default,
+ unless `%parse-param {TYPE1 ARG1}' was used.
+
+ -- Method on parser: int parse ()
+ Run the syntactic analysis, and return 0 on success, 1 otherwise.
+
+ -- Method on parser: std::ostream& debug_stream ()
+ -- Method on parser: void set_debug_stream (std::ostream& O)
+ Get or set the stream used for tracing the parsing. It defaults to
+ `std::cerr'.
+
+ -- Method on parser: debug_level_type debug_level ()
+ -- Method on parser: void set_debug_level (debug_level L)
+ Get or set the tracing level. Currently its value is either 0, no
+ trace, or nonzero, full tracing.
+
+ -- Method on parser: void error (const location_type& L, const
+ std::string& M)
+ The definition for this member function must be supplied by the
+ user: the parser uses it to report a parser error occurring at L,
+ described by M.

+
+10.1.5 C++ Scanner Interface
+----------------------------
+
+The parser invokes the scanner by calling `yylex'. Contrary to C
+parsers, C++ parsers are always pure: there is no point in using the
+`%define api.pure' directive. Therefore the interface is as follows.
+
+ -- Method on parser: int yylex (semantic_type* YYLVAL, location_type*
+ YYLLOC, TYPE1 ARG1, ...)
+ Return the next token. Its type is the return value, its semantic
+ value and location being YYLVAL and YYLLOC. Invocations of
+ `%lex-param {TYPE1 ARG1}' yield additional arguments.

+-----------------------------
+
+This section demonstrates the use of a C++ parser with a simple but
+complete example. This example should be available on your system,
+ready to compile, in the directory "../bison/examples/calc++". It
+focuses on the use of Bison, therefore the design of the various C++
+classes is very naive: no accessors, no encapsulation of members etc.
+We will use a Lex scanner, and more precisely, a Flex scanner, to
+demonstrate the various interaction. A hand written scanner is
+actually easier to interface with.

+
+Of course the grammar is dedicated to arithmetics, a single expression,
+possibly preceded by variable assignments. An environment containing
+possibly predefined variables such as `one' and `two', is exchanged
+with the parser. An example of valid input follows.

+
+10.1.6.2 Calc++ Parsing Driver
+..............................
+
+To support a pure interface with the parser (and the scanner) the
+technique of the "parsing context" is convenient: a structure
+containing all the data to exchange. Since, in addition to simply
+launch the parsing, there are several auxiliary tasks to execute (open
+the file for parsing, instantiate the parser etc.), we recommend
+transforming the simple parsing context structure into a fully blown
+"parsing driver" class.
+
+ The declaration of this driver class, `calc++-driver.hh', is as
+follows. The first part includes the CPP guard and imports the
+required standard library components, and the declaration of the parser
+class.
+
+ #ifndef CALCXX_DRIVER_HH
+ # define CALCXX_DRIVER_HH
+ # include <string>
+ # include <map>
+ # include "calc++-parser.hh"
+
+Then comes the declaration of the scanning function. Flex expects the
+signature of `yylex' to be defined in the macro `YY_DECL', and the C++
+parser expects it to be declared. We can factor both as follows.
+
+ // Tell Flex the lexer's prototype ...
+ # define YY_DECL \
+ yy::calcxx_parser::token_type \
+ yylex (yy::calcxx_parser::semantic_type* yylval, \
+ yy::calcxx_parser::location_type* yylloc, \
+ calcxx_driver& driver)
+ // ... and declare it for the parser's sake.
+ YY_DECL;
+
+The `calcxx_driver' class is then declared with its most obvious
+members.
+
+ // Conducting the whole scanning and parsing of Calc++.
+ class calcxx_driver
+ {
+ public:
+ calcxx_driver ();
+ virtual ~calcxx_driver ();
+
+ std::map<std::string, int> variables;
+
+ int result;
+
+To encapsulate the coordination with the Flex scanner, it is useful to
+have two members function to open and close the scanning phase.
+
+ // Handling the scanner.
+ void scan_begin ();
+ void scan_end ();
+ bool trace_scanning;
+
+Similarly for the parser itself.
+
+ // Run the parser. Return 0 on success.
+ int parse (const std::string& f);
+ std::string file;
+ bool trace_parsing;
+
+To demonstrate pure handling of parse errors, instead of simply dumping
+them on the standard error output, we will pass them to the compiler
+driver using the following two member functions. Finally, we close the
+class declaration and CPP guard.
+
+ // Error handling.
+ void error (const yy::location& l, const std::string& m);
+ void error (const std::string& m);
+ };
+ #endif // ! CALCXX_DRIVER_HH
+
+ The implementation of the driver is straightforward. The `parse'
+member function deserves some attention. The `error' functions are
+simple stubs, they should actually register the located error messages
+and set error state.
+
+ #include "calc++-driver.hh"
+ #include "calc++-parser.hh"

+
+10.1.6.3 Calc++ Parser
+......................
+
+The grammar file `calc++-parser.yy' starts by asking for the C++
+deterministic parser skeleton, the creation of the parser header file,
+and specifies the name of the parser class. Because the C++ skeleton
+changed several times, it is safer to require the version you designed
+the grammar for.
+
+ %skeleton "lalr1.cc" /* -*- C++ -*- */
+ %require "2.5.91"
+ %defines
+ %define parser_class_name "calcxx_parser"
+
+Then come the declarations/inclusions needed to define the `%union'.
+Because the parser uses the parsing driver and reciprocally, both
+cannot include the header of the other. Because the driver's header
+needs detailed knowledge about the parser class (in particular its
+inner types), it is the parser's header which will simply use a forward
+declaration of the driver. *Note %code Summary::.
+
+ %code requires {
+ # include <string>
+ class calcxx_driver;
+ }
+
+The driver is passed by reference to the parser and to the scanner.
+This provides a simple but effective pure interface, not relying on
+global variables.
+
+ // The parsing context.
+ %parse-param { calcxx_driver& driver }
+ %lex-param { calcxx_driver& driver }
+
+Then we request the location tracking feature, and initialize the first
+location's file name. Afterward new locations are computed relatively
+to the previous locations: the file name will be automatically
+propagated.
+
+ %locations
+ %initial-action
+ {
+ // Initialize the initial location.
+ @$.begin.filename = @$.end.filename = &driver.file;
+ };
+
+Use the two following directives to enable parser tracing and verbose
+error messages. However, verbose error messages can contain incorrect
+information (*note LAC::).
+
+ %debug
+ %error-verbose
+
+Semantic values cannot use "real" objects, but only pointers to them.
+
+ // Symbols.
+ %union
+ {
+ int ival;
+ std::string *sval;
+ };
+
+The code between `%code {' and `}' is output in the `*.cc' file; it
+needs detailed knowledge about the driver.
+
+ %code {
+ # include "calc++-driver.hh"
+ }
+
+The token numbered as 0 corresponds to end of file; the following line
+allows for nicer error messages referring to "end of file" instead of
+"$end". Similarly user friendly named are provided for each symbol.
+Note that the tokens names are prefixed by `TOKEN_' to avoid name
+clashes.
+
+ %token END 0 "end of file"
+ %token ASSIGN ":="
+ %token <sval> IDENTIFIER "identifier"
+ %token <ival> NUMBER "number"
+ %type <ival> exp
+
+To enable memory deallocation during error recovery, use `%destructor'.
+
+ %printer { yyoutput << *$$; } "identifier"
+ %destructor { delete $$; } "identifier"
+
+ %printer { yyoutput << $$; } <ival>
+
+The grammar itself is straightforward.
+
+ %%
+ %start unit;
+ unit: assignments exp { driver.result = $2; };
+
+ assignments:
+ /* Nothing. */ {}
+ | assignments assignment {};
+
+ assignment:
+ "identifier" ":=" exp
+ { driver.variables[*$1] = $3; delete $1; };
+
+ %left '+' '-';
+ %left '*' '/';
+ exp: exp '+' exp { $$ = $1 + $3; }
+ | exp '-' exp { $$ = $1 - $3; }
+ | exp '*' exp { $$ = $1 * $3; }
+ | exp '/' exp { $$ = $1 / $3; }
+ | "identifier" { $$ = driver.variables[*$1]; delete $1; }
+ | "number" { $$ = $1; };
+ %%
+
+Finally the `error' member function registers the errors to the driver.
+
+ void
+ yy::calcxx_parser::error (const yy::calcxx_parser::location_type& l,
+ const std::string& m)
+ {
+ driver.error (l, m);

+10.1.6.4 Calc++ Scanner
+.......................
+
+The Flex scanner first includes the driver declaration, then the
+parser's to get the set of defined tokens.
+
+ %{ /* -*- C++ -*- */
+ # include <cstdlib>
+ # include <cerrno>
+ # include <climits>
+ # include <string>

+ 2.5.31 through 2.5.33): it generates code that does
+ not conform to C89. See Debian bug 333231
+ <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333231>. */
+ # undef yywrap
+ # define yywrap() 1
+
+ /* By default yylex returns int, we use token_type.
+ Unfortunately yyterminate by default returns 0, which is
+ not of token_type. */
+ #define yyterminate() return token::END
+ %}
+
+Because there is no `#include'-like feature we don't need `yywrap', we
+don't need `unput' either, and we parse an actual file, this is not an
+interactive session with the user. Finally we enable the scanner
+tracing features.
+
+ %option noyywrap nounput batch debug
+
+Abbreviations allow for more readable rules.
+
+ id [a-zA-Z][a-zA-Z_0-9]*
+ int [0-9]+
+ blank [ \t]
+
+The following paragraph suffices to track locations accurately. Each
+time `yylex' is invoked, the begin position is moved onto the end
+position. Then when a pattern is matched, the end position is advanced
+of its width. In case it matched ends of lines, the end cursor is
+adjusted, and each time blanks are matched, the begin cursor is moved
+onto the end cursor to effectively ignore the blanks preceding tokens.
+Comments would be treated equally.
+
+ %{
+ # define YY_USER_ACTION yylloc->columns (yyleng);
+ %}
+ %%
+ %{
+ yylloc->step ();
+ %}
+ {blank}+ yylloc->step ();
+ [\n]+ yylloc->lines (yyleng); yylloc->step ();
+
+The rules are simple, just note the use of the driver to report errors.
+It is convenient to use a typedef to shorten
+`yy::calcxx_parser::token::identifier' into `token::identifier' for
+instance.
+
+ %{
+ typedef yy::calcxx_parser::token token;
+ %}
+ /* Convert ints to the actual type of tokens. */
+ [-+*/] return yy::calcxx_parser::token_type (yytext[0]);
+ ":=" return token::ASSIGN;
+ {int} {
+ errno = 0;
+ long n = strtol (yytext, NULL, 10);
+ if (! (INT_MIN <= n && n <= INT_MAX && errno != ERANGE))
+ driver.error (*yylloc, "integer is out of range");
+ yylval->ival = n;
+ return token::NUMBER;
+ }
+ {id} yylval->sval = new std::string (yytext); return token::IDENTIFIER;
+ . driver.error (*yylloc, "invalid character");
+ %%
+
+Finally, because the scanner related driver's member function depend on
+the scanner's data, it is simpler to implement them in this file.
+
+ void
+ calcxx_driver::scan_begin ()
+ {
+ yy_flex_debug = trace_scanning;

+
+10.2.1 Java Bison Interface
+---------------------------
+
+(The current Java interface is experimental and may evolve. More user
+feedback will help to stabilize it.)
+
+ The Java parser skeletons are selected using the `%language "Java"'
+directive or the `-L java'/`--language=java' option.
+
+ When generating a Java parser, `bison BASENAME.y' will create a
+single Java source file named `BASENAME.java' containing the parser
+implementation. Using a grammar file without a `.y' suffix is
+currently broken. The basename of the parser implementation file can
+be changed by the `%file-prefix' directive or the `-p'/`--name-prefix'
+option. The entire parser implementation file name can be changed by
+the `%output' directive or the `-o'/`--output' option. The parser
+implementation file contains a single class for the parser.
+
+ You can create documentation for generated parsers using Javadoc.
+
+ Contrary to C parsers, Java parsers do not use global variables; the
+state of the parser is always local to an instance of the parser class.
+Therefore, all Java parsers are "pure", and the `%pure-parser' and
+`%define api.pure' directives does not do anything when used in Java.
+
+ Push parsers are currently unsupported in Java and `%define
+api.push-pull' have no effect.
+
+ GLR parsers are currently unsupported in Java. Do not use the
+`glr-parser' directive.
+
+ No header file can be generated for Java parsers. Do not use the
+`%defines' directive or the `-d'/`--defines' options.
+
+ Currently, support for debugging and verbose errors are always
+compiled in. Thus the `%debug' and `%token-table' directives and the
+`-t'/`--debug' and `-k'/`--token-table' options have no effect. This
+may change in the future to eliminate unused code in the generated
+parser, so use `%debug' and `%verbose-error' explicitly if needed.
+Also, in the future the `%token-table' directive might enable a public
+interface to access the token names and codes.
+
+\1f
+File: bison.info, Node: Java Semantic Values, Next: Java Location Values, Prev: Java Bison Interface, Up: Java Parsers
+
+10.2.2 Java Semantic Values
+---------------------------
+
+There is no `%union' directive in Java parsers. Instead, the semantic
+values' types (class names) should be specified in the `%type' or
+`%token' directive:
+
+ %type <Expression> expr assignment_expr term factor
+ %type <Integer> number
+
+ By default, the semantic stack is declared to have `Object' members,
+which means that the class types you specify can be of any class. To
+improve the type safety of the parser, you can declare the common
+superclass of all the semantic values using the `%define stype'
+directive. For example, after the following declaration:
+
+ %define stype "ASTNode"
+
+any `%type' or `%token' specifying a semantic type which is not a
+subclass of ASTNode, will cause a compile-time error.
+
+ Types used in the directives may be qualified with a package name.
+Primitive data types are accepted for Java version 1.5 or later. Note
+that in this case the autoboxing feature of Java 1.5 will be used.
+Generic types may not be used; this is due to a limitation in the
+implementation of Bison, and may change in future releases.
+
+ Java parsers do not support `%destructor', since the language adopts
+garbage collection. The parser will try to hold references to semantic
+values for as little time as needed.
+
+ Java parsers do not support `%printer', as `toString()' can be used
+to print the semantic values. This however may change (in a
+backwards-compatible way) in future versions of Bison.
+
+\1f
+File: bison.info, Node: Java Location Values, Next: Java Parser Interface, Prev: Java Semantic Values, Up: Java Parsers
+
+10.2.3 Java Location Values
+---------------------------
+
+When the directive `%locations' is used, the Java parser supports
+location tracking, see *note Tracking Locations::. An auxiliary
+user-defined class defines a "position", a single point in a file;
+Bison itself defines a class representing a "location", a range
+composed of a pair of positions (possibly spanning several files). The
+location class is an inner class of the parser; the name is `Location'
+by default, and may also be renamed using `%define location_type
+"CLASS-NAME"'.
+
+ The location class treats the position as a completely opaque value.
+By default, the class name is `Position', but this can be changed with
+`%define position_type "CLASS-NAME"'. This class must be supplied by
+the user.
+
+ -- Instance Variable of Location: Position begin
+ -- Instance Variable of Location: Position end
+ The first, inclusive, position of the range, and the first beyond.
+
+ -- Constructor on Location: Location (Position LOC)
+ Create a `Location' denoting an empty range located at a given
+ point.
+
+ -- Constructor on Location: Location (Position BEGIN, Position END)
+ Create a `Location' from the endpoints of the range.
+
+ -- Method on Location: String toString ()
+ Prints the range represented by the location. For this to work
+ properly, the position class should override the `equals' and
+ `toString' methods appropriately.
+
+\1f
+File: bison.info, Node: Java Parser Interface, Next: Java Scanner Interface, Prev: Java Location Values, Up: Java Parsers
+
+10.2.4 Java Parser Interface
+----------------------------
+
+The name of the generated parser class defaults to `YYParser'. The
+`YY' prefix may be changed using the `%name-prefix' directive or the
+`-p'/`--name-prefix' option. Alternatively, use `%define
+parser_class_name "NAME"' to give a custom name to the class. The
+interface of this class is detailed below.
+
+ By default, the parser class has package visibility. A declaration
+`%define public' will change to public visibility. Remember that,
+according to the Java language specification, the name of the `.java'
+file should match the name of the class in this case. Similarly, you
+can use `abstract', `final' and `strictfp' with the `%define'
+declaration to add other modifiers to the parser class.
+
+ The Java package name of the parser class can be specified using the
+`%define package' directive. The superclass and the implemented
+interfaces of the parser class can be specified with the `%define
+extends' and `%define implements' directives.
+
+ The parser class defines an inner class, `Location', that is used
+for location tracking (see *note Java Location Values::), and a inner
+interface, `Lexer' (see *note Java Scanner Interface::). Other than
+these inner class/interface, and the members described in the interface
+below, all the other members and fields are preceded with a `yy' or
+`YY' prefix to avoid clashes with user code.
+
+ The parser class can be extended using the `%parse-param' directive.
+Each occurrence of the directive will add a `protected final' field to
+the parser class, and an argument to its constructor, which initialize
+them automatically.
+
+ Token names defined by `%token' and the predefined `EOF' token name
+are added as constant fields to the parser class.
+
+ -- Constructor on YYParser: YYParser (LEX_PARAM, ..., PARSE_PARAM,
+ ...)
+ Build a new parser object with embedded `%code lexer'. There are
+ no parameters, unless `%parse-param's and/or `%lex-param's are
+ used.
+
+ -- Constructor on YYParser: YYParser (Lexer LEXER, PARSE_PARAM, ...)
+ Build a new parser object using the specified scanner. There are
+ no additional parameters unless `%parse-param's are used.
+
+ If the scanner is defined by `%code lexer', this constructor is
+ declared `protected' and is called automatically with a scanner
+ created with the correct `%lex-param's.
+
+ -- Method on YYParser: boolean parse ()
+ Run the syntactic analysis, and return `true' on success, `false'
+ otherwise.
+
+ -- Method on YYParser: boolean recovering ()
+ During the syntactic analysis, return `true' if recovering from a
+ syntax error. *Note Error Recovery::.
+
+ -- Method on YYParser: java.io.PrintStream getDebugStream ()
+ -- Method on YYParser: void setDebugStream (java.io.printStream O)
+ Get or set the stream used for tracing the parsing. It defaults to
+ `System.err'.
+
+ -- Method on YYParser: int getDebugLevel ()
+ -- Method on YYParser: void setDebugLevel (int L)
+ Get or set the tracing level. Currently its value is either 0, no
+ trace, or nonzero, full tracing.

+File: bison.info, Node: Java Scanner Interface, Next: Java Action Features, Prev: Java Parser Interface, Up: Java Parsers
+
+10.2.5 Java Scanner Interface
+-----------------------------
+
+There are two possible ways to interface a Bison-generated Java parser
+with a scanner: the scanner may be defined by `%code lexer', or defined
+elsewhere. In either case, the scanner has to implement the `Lexer'
+inner interface of the parser class.
+
+ In the first case, the body of the scanner class is placed in `%code
+lexer' blocks. If you want to pass parameters from the parser
+constructor to the scanner constructor, specify them with `%lex-param';
+they are passed before `%parse-param's to the constructor.
+
+ In the second case, the scanner has to implement the `Lexer'
+interface, which is defined within the parser class (e.g.,
+`YYParser.Lexer'). The constructor of the parser object will then
+accept an object implementing the interface; `%lex-param' is not used
+in this case.
+
+ In both cases, the scanner has to implement the following methods.
+
+ -- Method on Lexer: void yyerror (Location LOC, String MSG)
+ This method is defined by the user to emit an error message. The
+ first parameter is omitted if location tracking is not active.
+ Its type can be changed using `%define location_type "CLASS-NAME".'
+
+ -- Method on Lexer: int yylex ()
+ Return the next token. Its type is the return value, its semantic
+ value and location are saved and returned by the their methods in
+ the interface.
+
+ Use `%define lex_throws' to specify any uncaught exceptions.
+ Default is `java.io.IOException'.
+
+ -- Method on Lexer: Position getStartPos ()
+ -- Method on Lexer: Position getEndPos ()
+ Return respectively the first position of the last token that
+ `yylex' returned, and the first position beyond it. These methods
+ are not needed unless location tracking is active.
+
+ The return type can be changed using `%define position_type
+ "CLASS-NAME".'
+
+ -- Method on Lexer: Object getLVal ()
+ Return the semantic value of the last token that yylex returned.
+
+ The return type can be changed using `%define stype "CLASS-NAME".'

+
+10.2.6 Special Features for Use in Java Actions
+-----------------------------------------------
+
+The following special constructs can be uses in Java actions. Other
+analogous C action features are currently unavailable for Java.
+
+ Use `%define throws' to specify any uncaught exceptions from parser
+actions, and initial actions specified by `%initial-action'.
+
+ -- Variable: $N
+ The semantic value for the Nth component of the current rule.
+ This may not be assigned to. *Note Java Semantic Values::.
+
+ -- Variable: $<TYPEALT>N
+ Like `$N' but specifies a alternative type TYPEALT. *Note Java
+ Semantic Values::.
+
+ -- Variable: $$
+ The semantic value for the grouping made by the current rule. As a
+ value, this is in the base type (`Object' or as specified by
+ `%define stype') as in not cast to the declared subtype because
+ casts are not allowed on the left-hand side of Java assignments.
+ Use an explicit Java cast if the correct subtype is needed. *Note
+ Java Semantic Values::.
+
+ -- Variable: $<TYPEALT>$
+ Same as `$$' since Java always allow assigning to the base type.
+ Perhaps we should use this and `$<>$' for the value and `$$' for
+ setting the value but there is currently no easy way to distinguish
+ these constructs. *Note Java Semantic Values::.
+
+ -- Variable: @N
+ The location information of the Nth component of the current rule.
+ This may not be assigned to. *Note Java Location Values::.
+
+ -- Variable: @$
+ The location information of the grouping made by the current rule.
+ *Note Java Location Values::.
+
+ -- Statement: return YYABORT `;'
+ Return immediately from the parser, indicating failure. *Note
+ Java Parser Interface::.
+
+ -- Statement: return YYACCEPT `;'
+ Return immediately from the parser, indicating success. *Note
+ Java Parser Interface::.
+
+ -- Statement: return YYERROR `;'
+ Start error recovery (without printing an error message). *Note
+ Error Recovery::.
+
+ -- Function: boolean recovering ()
+ Return whether error recovery is being done. In this state, the
+ parser reads token until it reaches a known state, and then
+ restarts normal operation. *Note Error Recovery::.
+
+ -- Function: protected void yyerror (String msg)
+ -- Function: protected void yyerror (Position pos, String msg)
+ -- Function: protected void yyerror (Location loc, String msg)
+ Print an error message using the `yyerror' method of the scanner
+ instance in use.

+
+10.2.7 Differences between C/C++ and Java Grammars
+--------------------------------------------------
+
+The different structure of the Java language forces several differences
+between C/C++ grammars, and grammars designed for Java parsers. This
+section summarizes these differences.
+
+ * Java lacks a preprocessor, so the `YYERROR', `YYACCEPT', `YYABORT'
+ symbols (*note Table of Symbols::) cannot obviously be macros.
+ Instead, they should be preceded by `return' when they appear in
+ an action. The actual definition of these symbols is opaque to
+ the Bison grammar, and it might change in the future. The only
+ meaningful operation that you can do, is to return them. *Note
+ Java Action Features::.
+
+ Note that of these three symbols, only `YYACCEPT' and `YYABORT'
+ will cause a return from the `yyparse' method(1).
+
+ * Java lacks unions, so `%union' has no effect. Instead, semantic
+ values have a common base type: `Object' or as specified by
+ `%define stype'. Angle brackets on `%token', `type', `$N' and
+ `$$' specify subtypes rather than fields of an union. The type of
+ `$$', even with angle brackets, is the base type since Java casts
+ are not allow on the left-hand side of assignments. Also, `$N'
+ and `@N' are not allowed on the left-hand side of assignments.
+ *Note Java Semantic Values::, and *note Java Action Features::.
+
+ * The prologue declarations have a different meaning than in C/C++
+ code.
+ `%code imports'
+ blocks are placed at the beginning of the Java source code.
+ They may include copyright notices. For a `package'
+ declarations, it is suggested to use `%define package'
+ instead.
+
+ unqualified `%code'
+ blocks are placed inside the parser class.
+
+ `%code lexer'
+ blocks, if specified, should include the implementation of the
+ scanner. If there is no such block, the scanner can be any
+ class that implements the appropriate interface (*note Java
+ Scanner Interface::).
+
+ Other `%code' blocks are not supported in Java parsers. In
+ particular, `%{ ... %}' blocks should not be used and may give an
+ error in future versions of Bison.
+
+ The epilogue has the same meaning as in C/C++ code and it can be
+ used to define other classes used by the parser _outside_ the
+ parser class.
+
+ ---------- Footnotes ----------
+
+ (1) Java parsers include the actions in a separate method than
+`yyparse' in order to have an intuitive syntax that corresponds to
+these C macros.

+
+11.1 Memory Exhausted

+ What can I do?
+
+ This question is already addressed elsewhere, see *note Recursive
+Rules: Recursion.
+
+\1f
+File: bison.info, Node: How Can I Reset the Parser, Next: Strings are Destroyed, Prev: Memory Exhausted, Up: FAQ
+
+11.2 How Can I Reset the Parser
+===============================
+
+The following phenomenon has several symptoms, resulting in the
+following typical questions:
+
+ I invoke `yyparse' several times, and on correct input it works
+ properly; but when a parse error is found, all the other calls fail
+ too. How can I reset the error flag of `yyparse'?
+
+or
+
+ My parser includes support for an `#include'-like feature, in
+ which case I run `yyparse' from `yyparse'. This fails although I
+ did specify `%define api.pure'.
+
+ These problems typically come not from Bison itself, but from
+Lex-generated scanners. Because these scanners use large buffers for
+speed, they might not notice a change of input file. As a
+demonstration, consider the following source file, `first-line.l':
+
+ %{
+ #include <stdio.h>
+ #include <stdlib.h>
+ %}
+ %%
+ .*\n ECHO; return 1;
+ %%
+ int
+ yyparse (char const *file)
+ {
+ yyin = fopen (file, "r");
+ if (!yyin)
+ {
+ perror ("fopen");
+ exit (EXIT_FAILURE);
+ }
+ /* One token only. */
+ yylex ();
+ if (fclose (yyin) != 0)
+ {
+ perror ("fclose");
+ exit (EXIT_FAILURE);
+ }
+ return 0;
+ }
+
+ int
+ main (void)
+ {
+ yyparse ("input");
+ yyparse ("input");
+ return 0;
+ }
+
+If the file `input' contains
+
+ input:1: Hello,
+ input:2: World!
+
+then instead of getting the first line twice, you get:
+
+ $ flex -ofirst-line.c first-line.l
+ $ gcc -ofirst-line first-line.c -ll
+ $ ./first-line
+ input:1: Hello,
+ input:2: World!
+
+ Therefore, whenever you change `yyin', you must tell the
+Lex-generated scanner to discard its current buffer and switch to the
+new one. This depends upon your implementation of Lex; see its
+documentation for more. For Flex, it suffices to call
+`YY_FLUSH_BUFFER' after each change to `yyin'. If your Flex-generated
+scanner needs to read from several input streams to handle features
+like include files, you might consider using Flex functions like
+`yy_switch_to_buffer' that manipulate multiple input buffers.
+
+ If your Flex-generated scanner uses start conditions (*note Start
+conditions: (flex)Start conditions.), you might also want to reset the
+scanner's state, i.e., go back to the initial start condition, through
+a call to `BEGIN (0)'.
+
+\1f
+File: bison.info, Node: Strings are Destroyed, Next: Implementing Gotos/Loops, Prev: How Can I Reset the Parser, Up: FAQ
+
+11.3 Strings are Destroyed
+==========================
+
+ My parser seems to destroy old strings, or maybe it loses track of
+ them. Instead of reporting `"foo", "bar"', it reports `"bar",
+ "bar"', or even `"foo\nbar", "bar"'.
+
+ This error is probably the single most frequent "bug report" sent to
+Bison lists, but is only concerned with a misunderstanding of the role
+of the scanner. Consider the following Lex code:
+
+ %{
+ #include <stdio.h>
+ char *yylval = NULL;
+ %}
+ %%
+ .* yylval = yytext; return 1;
+ \n /* IGNORE */
+ %%
+ int
+ main ()
+ {
+ /* Similar to using $1, $2 in a Bison action. */
+ char *fst = (yylex (), yylval);
+ char *snd = (yylex (), yylval);
+ printf ("\"%s\", \"%s\"\n", fst, snd);
+ return 0;
+ }
+
+ If you compile and run this code, you get:
+
+ $ flex -osplit-lines.c split-lines.l
+ $ gcc -osplit-lines split-lines.c -ll
+ $ printf 'one\ntwo\n' | ./split-lines
+ "one
+ two", "two"
+
+this is because `yytext' is a buffer provided for _reading_ in the
+action, but if you want to keep it, you have to duplicate it (e.g.,
+using `strdup'). Note that the output may depend on how your
+implementation of Lex handles `yytext'. For instance, when given the
+Lex compatibility option `-l' (which triggers the option `%array') Flex
+generates a different behavior:
+
+ $ flex -l -osplit-lines.c split-lines.l
+ $ gcc -osplit-lines split-lines.c -ll
+ $ printf 'one\ntwo\n' | ./split-lines
+ "two", "two"
+

+
+11.4 Implementing Gotos/Loops
+=============================
+
+ My simple calculator supports variables, assignments, and
+ functions, but how can I implement gotos, or loops?
+
+ Although very pedagogical, the examples included in the document blur
+the distinction to make between the parser--whose job is to recover the
+structure of a text and to transmit it to subsequent modules of the
+program--and the processing (such as the execution) of this structure.
+This works well with so called straight line programs, i.e., precisely
+those that have a straightforward execution model: execute simple
+instructions one after the others.
+
+ If you want a richer model, you will probably need to use the parser
+to construct a tree that does represent the structure it has recovered;
+this tree is usually called the "abstract syntax tree", or "AST" for
+short. Then, walking through this tree, traversing it in various ways,
+will enable treatments such as its execution or its translation, which
+will result in an interpreter or a compiler.
+
+ This topic is way beyond the scope of this manual, and the reader is
+invited to consult the dedicated literature.
+
+\1f
+File: bison.info, Node: Multiple start-symbols, Next: Secure? Conform?, Prev: Implementing Gotos/Loops, Up: FAQ
+
+11.5 Multiple start-symbols
+===========================
+
+ I have several closely related grammars, and I would like to share
+ their implementations. In fact, I could use a single grammar but
+ with multiple entry points.
+
+ Bison does not support multiple start-symbols, but there is a very
+simple means to simulate them. If `foo' and `bar' are the two pseudo
+start-symbols, then introduce two new tokens, say `START_FOO' and
+`START_BAR', and use them as switches from the real start-symbol:
+
+ %token START_FOO START_BAR;
+ %start start;
+ start:
+ START_FOO foo
+ | START_BAR bar;
+
+ These tokens prevents the introduction of new conflicts. As far as
+the parser goes, that is all that is needed.
+
+ Now the difficult part is ensuring that the scanner will send these
+tokens first. If your scanner is hand-written, that should be
+straightforward. If your scanner is generated by Lex, them there is
+simple means to do it: recall that anything between `%{ ... %}' after
+the first `%%' is copied verbatim in the top of the generated `yylex'
+function. Make sure a variable `start_token' is available in the
+scanner (e.g., a global variable or using `%lex-param' etc.), and use
+the following:
+
+ /* Prologue. */
+ %%
+ %{
+ if (start_token)
+ {
+ int t = start_token;
+ start_token = 0;
+ return t;
+ }
+ %}
+ /* The rules. */

+ I can't build Bison because `make' complains that `msgfmt' is not
+ found. What should I do?
+
+ Like most GNU packages with internationalization support, that
+feature is turned on by default. If you have problems building in the
+`po' subdirectory, it indicates that your system's internationalization
+support is lacking. You can re-configure Bison with `--disable-nls' to
+turn off this support, or you can install GNU gettext from
+`ftp://ftp.gnu.org/gnu/gettext/' and re-configure Bison. See the file
+`ABOUT-NLS' for more information.

+
+11.9 Bug Reports
+================
+
+ I found a bug. What should I include in the bug report?
+
+ Before you send a bug report, make sure you are using the latest
+version. Check `ftp://ftp.gnu.org/pub/gnu/bison/' or one of its
+mirrors. Be sure to include the version number in your bug report. If
+the bug is present in the latest version but not in a previous version,
+try to determine the most recent version which did not contain the bug.
+
+ If the bug is parser-related, you should include the smallest grammar
+you can which demonstrates the bug. The grammar file should also be
+complete (i.e., I should be able to run it through Bison without having
+to edit or add anything). The smaller and simpler the grammar, the
+easier it will be to fix the bug.
+
+ Include information about your compilation environment, including
+your operating system's name and version and your compiler's name and
+version. If you have trouble compiling, you should also include a
+transcript of the build session, starting with the invocation of
+`configure'. Depending on the nature of the bug, you may be asked to
+send additional files as well (such as `config.h' or `config.cache').
+
+ Patches are most welcome, but not required. That is, do not
+hesitate to send a bug report just because you cannot provide a fix.
+
+ Send bug reports to <bug-bison@gnu.org>.

+
+11.11 Beta Testing
+==================
+
+ What is involved in being a beta tester?
+
+ It's not terribly involved. Basically, you would download a test
+release, compile it, and use it to build and run a parser or two. After
+that, you would submit either a bug report or a message saying that
+everything is okay. It is important to report successes as well as
+failures because test releases eventually become mainstream releases,
+but only if they are adequately tested. If no one tests, development is
+essentially halted.
+
+ Beta testers are particularly needed for operating systems to which
+the developers do not have easy access. They currently have easy
+access to recent GNU/Linux and Solaris versions. Reports about other
+operating systems are especially welcome.

+ parse time to resolve reduce/reduce conflicts. *Note Writing GLR
+ Parsers: GLR Parsers.
+
+ -- Symbol: $end
+ The predefined token marking the end of the token stream. It
+ cannot be used in the grammar.
+
+ -- Symbol: error
+ A token name reserved for error recovery. This token may be used
+ in grammar rules so as to allow the Bison parser to recognize an
+ error in the grammar without halting the process. In effect, a
+ sentence containing an error may be recognized as valid. On a
+ syntax error, the token `error' becomes the current lookahead
+ token. Actions corresponding to `error' are then executed, and
+ the lookahead token is reset to the token that originally caused
+ the violation. *Note Error Recovery::.
+
+ -- Directive: %error-verbose
+ Bison declaration to request verbose, specific error message
+ strings when `yyerror' is called. *Note Error Reporting::.

+
+ -- Directive: %merge

+ merging function, the function is applied to the two semantic
+ values to get a single result. *Note Writing GLR Parsers: GLR
+ Parsers.
+
+ -- Directive: %name-prefix "PREFIX"
+ Obsoleted by the `%define' variable `api.prefix' (*note Multiple
+ Parsers in the Same Program: Multiple Parsers.).
+
+ Rename the external symbols (variables and functions) used in the
+ parser so that they start with PREFIX instead of `yy'. Contrary to
+ `api.prefix', do no rename types and macros.
+
+ The precise list of symbols renamed in C parsers is `yyparse',
+ `yylex', `yyerror', `yynerrs', `yylval', `yychar', `yydebug', and
+ (if locations are used) `yylloc'. If you use a push parser,
+ `yypush_parse', `yypull_parse', `yypstate', `yypstate_new' and
+ `yypstate_delete' will also be renamed. For example, if you use
+ `%name-prefix "c_"', the names become `c_parse', `c_lex', and so
+ on. For C++ parsers, see the `%define namespace' documentation in

+ -- Directive: %union
+ Bison declaration to specify several possible data types for
+ semantic values. *Note The Collection of Value Types: Union Decl.
+
+ -- Macro: YYABORT
+ Macro to pretend that an unrecoverable syntax error has occurred,
+ by making `yyparse' return 1 immediately. The error reporting
+ function `yyerror' is not called. *Note The Parser Function
+ `yyparse': Parser Function.
+
+ For Java parsers, this functionality is invoked using `return

+
+ -- Macro: YYACCEPT
+ Macro to pretend that a complete utterance of the language has been

+ Macro to discard a value from the parser stack and fake a lookahead
+ token. *Note Special Features for Use in Actions: Action Features.
+
+ -- Variable: yychar
+ External integer variable that contains the integer value of the

+
+ -- Macro: yyerrok
+ Macro to cause parser to recover immediately to its normal mode
+ after a syntax error. *Note Error Recovery::.
+
+ -- Macro: YYERROR
+ Cause an immediate syntax error. This statement initiates error
+ recovery just as if the parser itself had detected an error;
+ however, it does not call `yyerror', and does not print any
+ message. If you want to print an error message, call `yyerror'
+ explicitly before the `YYERROR;' statement. *Note Error
+ Recovery::.
+
+ For Java parsers, this functionality is invoked using `return
+ YYERROR;' instead.
+
+ -- Function: yyerror
+ User-supplied function to be called by `yyparse' on error. *Note
+ The Error Reporting Function `yyerror': Error Reporting.
+
+ -- Macro: YYERROR_VERBOSE
+ An obsolete macro that you define with `#define' in the prologue
+ to request verbose, specific error message strings when `yyerror'

+ *Note Calling Conventions for Pure Parsers: Pure Calling.
+
+ -- Variable: yylloc
+ External variable in which `yylex' should place the line and column
+ numbers associated with a token. (In a pure parser, it is a local
+ variable within `yyparse', and its address is passed to `yylex'.)
+ You can ignore this variable if you don't use the `@' feature in
+ the grammar actions. *Note Textual Locations of Tokens: Token
+ Locations. In semantic actions, it stores the location of the
+ lookahead token. *Note Actions and Locations: Actions and
+ Locations.
+

+ *Note Data Types of Locations: Location Type.
+
+ -- Variable: yylval
+ External variable in which `yylex' should place the semantic value
+ associated with a token. (In a pure parser, it is a local
+ variable within `yyparse', and its address is passed to `yylex'.)
+ *Note Semantic Values of Tokens: Token Values. In semantic
+ actions, it stores the semantic value of the lookahead token.
+ *Note Actions: Actions.
+
+ -- Macro: YYMAXDEPTH
+ Macro for specifying the maximum size of the parser stack. *Note
+ Memory Management::.
+
+ -- Variable: yynerrs
+ Global variable which Bison increments each time it reports a

+ -- Function: yyparse
+ The parser function produced by Bison; call this function to start
+ parsing. *Note The Parser Function `yyparse': Parser Function.

+ The function to delete a parser instance, produced by Bison in
+ push mode; call this function to delete the memory associated with
+ a parser. *Note The Parser Delete Function `yypstate_delete':

+ experimental and may evolve. More user feedback will help to
+ stabilize it.)
+
+ -- Function: yypstate_new
+ The function to create a parser instance, produced by Bison in
+ push mode; call this function to create a new parser. *Note The
+ Parser Create Function `yypstate_new': Parser Create Function.
+ (The current push parsing interface is experimental and may evolve.

+
+ -- Macro: YYRECOVERING
+ The expression `YYRECOVERING ()' yields 1 when the parser is
+ recovering from a syntax error, and 0 otherwise. *Note Special
+ Features for Use in Actions: Action Features.
+
+ -- Macro: YYSTACK_USE_ALLOCA
+ Macro used to control the use of `alloca' when the deterministic
+ parser in C needs to extend its stacks. If defined to 0, the
+ parser will use `malloc' to extend its stacks. If defined to 1,
+ the parser will use `alloca'. Values other than 0 and 1 are
+ reserved for future Bison extensions. If not defined,
+ `YYSTACK_USE_ALLOCA' defaults to 0.
+
+ In the all-too-common case where your code may run on a host with a
+ limited stack and with unreliable stack-overflow checking, you
+ should set `YYMAXDEPTH' to a value that cannot possibly result in
+ unchecked stack overflow on any of your target hosts when `alloca'
+ is called. You can inspect the code that Bison generates in order
+ to determine the proper numeric values. This will require some
+ expertise in low-level implementation details.
+
+ -- Type: YYSTYPE
+ Data type of semantic values; `int' by default. *Note Data Types
+ of Semantic Values: Value Type.

+*****************
+
+Accepting state
+ A state whose only action is the accept action. The accepting
+ state is thus a consistent state. *Note Understanding::.
+
+Backus-Naur Form (BNF; also called "Backus Normal Form")
+ Formal method of specifying context-free grammars originally
+ proposed by John Backus, and slightly improved by Peter Naur in
+ his 1960-01-02 committee document contributing to what became the
+ Algol 60 report. *Note Languages and Context-Free Grammars:
+ Language and Grammar.
+
+Consistent state
+ A state containing only one possible action. *Note Default
+ Reductions::.
+
+Context-free grammars
+ Grammars specified as rules that can be applied regardless of
+ context. Thus, if there is a rule which says that an integer can
+ be used as an expression, integers are allowed _anywhere_ an
+ expression is permitted. *Note Languages and Context-Free
+ Grammars: Language and Grammar.
+
+Default reduction
+ The reduction that a parser should perform if the current parser
+ state contains no other action for the lookahead token. In
+ permitted parser states, Bison declares the reduction with the
+ largest lookahead set to be the default reduction and removes that
+ lookahead set. *Note Default Reductions::.
+
+Defaulted state
+ A consistent state with a default reduction. *Note Default
+ Reductions::.
+
+Dynamic allocation
+ Allocation of memory that occurs during execution, rather than at
+ compile time or on entry to a function.
+
+Empty string
+ Analogous to the empty set in set theory, the empty string is a
+ character string of length zero.
+
+Finite-state stack machine
+ A "machine" that has discrete states in which it is said to exist
+ at each instant in time. As input to the machine is processed, the
+ machine moves from state to state as specified by the logic of the
+ machine. In the case of the parser, the input is the language
+ being parsed, and the states correspond to various stages in the
+ grammar rules. *Note The Bison Parser Algorithm: Algorithm.
+
+Generalized LR (GLR)
+ A parsing algorithm that can handle all context-free grammars,
+ including those that are not LR(1). It resolves situations that
+ Bison's deterministic parsing algorithm cannot by effectively
+ splitting off multiple parsers, trying all possible parsers, and
+ discarding those that fail in the light of additional right
+ context. *Note Generalized LR Parsing: Generalized LR Parsing.
+
+Grouping
+ A language construct that is (in general) grammatically divisible;
+ for example, `expression' or `declaration' in C. *Note Languages
+ and Context-Free Grammars: Language and Grammar.
+
+IELR(1) (Inadequacy Elimination LR(1))
+ A minimal LR(1) parser table construction algorithm. That is,
+ given any context-free grammar, IELR(1) generates parser tables
+ with the full language-recognition power of canonical LR(1) but
+ with nearly the same number of parser states as LALR(1). This
+ reduction in parser states is often an order of magnitude. More
+ importantly, because canonical LR(1)'s extra parser states may
+ contain duplicate conflicts in the case of non-LR(1) grammars, the
+ number of conflicts for IELR(1) is often an order of magnitude
+ less as well. This can significantly reduce the complexity of
+ developing a grammar. *Note LR Table Construction::.
+
+Infix operator
+ An arithmetic operator that is placed between the operands on
+ which it performs some operation.
+
+Input stream
+ A continuous flow of data between devices or programs.
+
+LAC (Lookahead Correction)
+ A parsing mechanism that fixes the problem of delayed syntax error
+ detection, which is caused by LR state merging, default
+ reductions, and the use of `%nonassoc'. Delayed syntax error
+ detection results in unexpected semantic actions, initiation of
+ error recovery in the wrong syntactic context, and an incorrect
+ list of expected tokens in a verbose syntax error message. *Note
+ LAC::.
+
+Language construct
+ One of the typical usage schemas of the language. For example,
+ one of the constructs of the C language is the `if' statement.
+ *Note Languages and Context-Free Grammars: Language and Grammar.
+
+Left associativity
+ Operators having left associativity are analyzed from left to
+ right: `a+b+c' first computes `a+b' and then combines with `c'.
+ *Note Operator Precedence: Precedence.
+
+Left recursion
+ A rule whose result symbol is also its first component symbol; for
+ example, `expseq1 : expseq1 ',' exp;'. *Note Recursive Rules:
+ Recursion.
+
+Left-to-right parsing
+ Parsing a sentence of a language by analyzing it token by token
+ from left to right. *Note The Bison Parser Algorithm: Algorithm.
+
+Lexical analyzer (scanner)
+ A function that reads an input stream and returns tokens one by
+ one. *Note The Lexical Analyzer Function `yylex': Lexical.
+
+Lexical tie-in
+ A flag, set by actions in the grammar rules, which alters the way
+ tokens are parsed. *Note Lexical Tie-ins::.
+
+Literal string token
+ A token which consists of two or more fixed characters. *Note
+ Symbols::.
+
+Lookahead token
+ A token already read but not yet shifted. *Note Lookahead Tokens:
+ Lookahead.
+
+LALR(1)
+ The class of context-free grammars that Bison (like most other
+ parser generators) can handle by default; a subset of LR(1).
+ *Note Mysterious Conflicts::.
+
+LR(1)
+ The class of context-free grammars in which at most one token of
+ lookahead is needed to disambiguate the parsing of any piece of
+ input.
+
+Nonterminal symbol
+ A grammar symbol standing for a grammatical construct that can be
+ expressed through rules in terms of smaller constructs; in other
+ words, a construct that is not a token. *Note Symbols::.
+
+Parser
+ A function that recognizes valid sentences of a language by
+ analyzing the syntax structure of a set of tokens passed to it
+ from a lexical analyzer.
+
+Postfix operator
+ An arithmetic operator that is placed after the operands upon
+ which it performs some operation.
+
+Reduction
+ Replacing a string of nonterminals and/or terminals with a single
+ nonterminal, according to a grammar rule. *Note The Bison Parser
+ Algorithm: Algorithm.
+
+Reentrant
+ A reentrant subprogram is a subprogram which can be in invoked any
+ number of times in parallel, without interference between the
+ various invocations. *Note A Pure (Reentrant) Parser: Pure Decl.
+
+Reverse polish notation
+ A language in which all operators are postfix operators.
+
+Right recursion
+ A rule whose result symbol is also its last component symbol; for
+ example, `expseq1: exp ',' expseq1;'. *Note Recursive Rules:
+ Recursion.
+
+Semantics
+ In computer languages, the semantics are specified by the actions
+ taken for each instance of the language, i.e., the meaning of each
+ statement. *Note Defining Language Semantics: Semantics.
+
+Shift
+ A parser is said to shift when it makes the choice of analyzing
+ further input from the stream rather than reducing immediately some
+ already-recognized rule. *Note The Bison Parser Algorithm:
+ Algorithm.
+
+Single-character literal
+ A single character that is recognized and interpreted as is.
+ *Note From Formal Rules to Bison Input: Grammar in Bison.
+
+Start symbol
+ The nonterminal symbol that stands for a complete valid utterance
+ in the language being parsed. The start symbol is usually listed
+ as the first nonterminal symbol in a language specification.
+ *Note The Start-Symbol: Start Decl.
+
+Symbol table
+ A data structure where symbol names and associated data are stored
+ during parsing to allow for recognition and use of existing
+ information in repeated uses of a symbol. *Note Multi-function
+ Calc::.
+
+Syntax error
+ An error encountered during parsing of an input stream due to
+ invalid syntax. *Note Error Recovery::.
+
+Token
+ A basic, grammatically indivisible unit of a language. The symbol
+ that describes a token in the grammar is a terminal symbol. The
+ input of the Bison parser is a stream of tokens which comes from
+ the lexical analyzer. *Note Symbols::.
+
+Terminal symbol
+ A grammar symbol that has no rules in the grammar and therefore is
+ grammatically indivisible. The piece of text it represents is a
+ token. *Note Languages and Context-Free Grammars: Language and
+ Grammar.
+
+Unreachable state
+ A parser state to which there does not exist a sequence of
+ transitions from the parser's start state. A state can become
+ unreachable during conflict resolution. *Note Unreachable
+ States::.

+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ 0. PREAMBLE
+
+ The purpose of this License is to make a manual, textbook, or other
+ functional and useful document "free" in the sense of freedom: to
+ assure everyone the effective freedom to copy and redistribute it,
+ with or without modifying it, either commercially or
+ noncommercially. Secondarily, this License preserves for the
+ author and publisher a way to get credit for their work, while not
+ being considered responsible for modifications made by others.
+
+ This License is a kind of "copyleft", which means that derivative
+ works of the document must themselves be free in the same sense.
+ It complements the GNU General Public License, which is a copyleft
+ license designed for free software.
+
+ We have designed this License in order to use it for manuals for
+ free software, because free software needs free documentation: a
+ free program should come with manuals providing the same freedoms
+ that the software does. But this License is not limited to
+ software manuals; it can be used for any textual work, regardless
+ of subject matter or whether it is published as a printed book.
+ We recommend this License principally for works whose purpose is
+ instruction or reference.
+
+ 1. APPLICABILITY AND DEFINITIONS
+
+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it
+ can be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You
+ accept the license if you copy, modify or distribute the work in a
+ way requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in
+ the notice that says that the Document is released under this
+ License. If a section does not fit the above definition of
+ Secondary then it is not allowed to be designated as Invariant.
+ The Document may contain zero Invariant Sections. If the Document
+ does not identify any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images
+ composed of pixels) generic paint programs or (for drawings) some
+ widely available drawing editor, and that is suitable for input to
+ text formatters or for automatic translation to a variety of
+ formats suitable for input to text formatters. A copy made in an
+ otherwise Transparent file format whose markup, or absence of
+ markup, has been arranged to thwart or discourage subsequent
+ modification by readers is not Transparent. An image format is
+ not Transparent if used for any substantial amount of text. A
+ copy that is not "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and
+ standard-conforming simple HTML, PostScript or PDF designed for
+ human modification. Examples of transparent image formats include
+ PNG, XCF and JPG. Opaque formats include proprietary formats that
+ can be read and edited only by proprietary word processors, SGML or
+ XML for which the DTD and/or processing tools are not generally
+ available, and the machine-generated HTML, PostScript or PDF
+ produced by some word processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow
+ the conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the
+ title equally prominent and visible. You may add other material
+ on the covers in addition. Copying with changes limited to the
+ covers, as long as they preserve the title of the Document and
+ satisfy these conditions, can be treated as verbatim copying in
+ other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a
+ machine-readable Transparent copy along with each Opaque copy, or
+ state in or with each Opaque copy a computer-network location from
+ which the general network-using public has access to download
+ using public-standard network protocols a complete Transparent
+ copy of the Document, free of added material. If you use the
+ latter option, you must take reasonably prudent steps, when you
+ begin distribution of Opaque copies in quantity, to ensure that
+ this Transparent copy will remain thus accessible at the stated
+ location until at least one year after the last time you
+ distribute an Opaque copy (directly or through your agents or
+ retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of
+ copies, to give them a chance to provide you with an updated
+ version of the Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with
+ the Modified Version filling the role of the Document, thus
+ licensing distribution and modification of the Modified Version to
+ whoever possesses a copy of it. In addition, you must do these
+ things in the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of
+ previous versions (which should, if there were any, be listed
+ in the History section of the Document). You may use the
+ same title as a previous version if the original publisher of
+ that version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on
+ the Title Page. If there is no section Entitled "History" in
+ the Document, create one stating the title, year, authors,
+ and publisher of the Document as given on its Title Page,
+ then add an item describing the Modified Version as stated in
+ the previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in
+ the "History" section. You may omit a network location for a
+ work that was published at least four years before the
+ Document itself, or if the original publisher of the version
+ it refers to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the
+ section all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section
+ titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option
+ designate some or all of these sections as invariant. To do this,
+ add their titles to the list of Invariant Sections in the Modified
+ Version's license notice. These titles must be distinct from any
+ other section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end
+ of the list of Cover Texts in the Modified Version. Only one
+ passage of Front-Cover Text and one of Back-Cover Text may be
+ added by (or through arrangements made by) any one entity. If the
+ Document already includes a cover text for the same cover,
+ previously added by you or by arrangement made by the same entity
+ you are acting on behalf of, you may not add another; but you may
+ replace the old one, on explicit permission from the previous
+ publisher that added the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination
+ all of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the
+ documents in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow
+ this License in all other respects regarding verbatim copying of
+ that document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of
+ a storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly
+ and finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from
+ you under this License. If your rights have been terminated and
+ not permanently reinstated, receipt of a copy of some or all of
+ the same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ `http://www.gnu.org/copyleft/'.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If
+ the Document does not specify a version number of this License,
+ you may choose any version ever published (not as a draft) by the
+ Free Software Foundation. If the Document specifies that a proxy
+ can decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+@node Introduction
+@unnumbered Introduction
+@cindex introduction
+
+@dfn{Bison} is a general-purpose parser generator that converts an
+annotated context-free grammar into a deterministic LR or generalized
+LR (GLR) parser employing LALR(1) parser tables. As an experimental
+feature, Bison can also generate IELR(1) or canonical LR(1) parser
+tables. Once you are proficient with Bison, you can use it to develop
+a wide range of language parsers, from those used in simple desk
+calculators to complex programming languages.
+
+Bison is upward compatible with Yacc: all properly-written Yacc
+grammars ought to work with Bison with no change. Anyone familiar
+with Yacc should be able to use Bison with little trouble. You need
+to be fluent in C or C++ programming in order to use Bison or to
+understand this manual. Java is also supported as an experimental
+feature.
+
+We begin with tutorial chapters that explain the basic concepts of
+using Bison and show three explained examples, each building on the
+last. If you don't know Bison or Yacc, start by reading these
+chapters. Reference chapters follow, which describe specific aspects
+of Bison in detail.
+
+Bison was written originally by Robert Corbett. Richard Stallman made
+it Yacc-compatible. Wilfred Hansen of Carnegie Mellon University
+added multi-character string literals and other features. Since then,
+Bison has grown more robust and evolved many other new features thanks
+to the hard work of a long list of volunteers. For details, see the
+@file{THANKS} and @file{ChangeLog} files included in the Bison
+distribution.
+
+This edition corresponds to version @value{VERSION} of Bison.
+
+@node Conditions
+@unnumbered Conditions for Using Bison
+
+The distribution terms for Bison-generated parsers permit using the
+parsers in nonfree programs. Before Bison version 2.2, these extra
+permissions applied only when Bison was generating LALR(1)
+parsers in C@. And before Bison version 1.24, Bison-generated
+parsers could be used only in programs that were free software.
+
+The other GNU programming tools, such as the GNU C
+compiler, have never
+had such a requirement. They could always be used for nonfree
+software. The reason Bison was different was not due to a special
+policy decision; it resulted from applying the usual General Public
+License to all of the Bison source code.
+
+The main output of the Bison utility---the Bison parser implementation
+file---contains a verbatim copy of a sizable piece of Bison, which is
+the code for the parser's implementation. (The actions from your
+grammar are inserted into this implementation at one point, but most
+of the rest of the implementation is not changed.) When we applied
+the GPL terms to the skeleton code for the parser's implementation,
+the effect was to restrict the use of Bison output to free software.
+
+We didn't change the terms because of sympathy for people who want to
+make software proprietary. @strong{Software should be free.} But we
+concluded that limiting Bison's use to free software was doing little to
+encourage people to make other software free. So we decided to make the
+practical conditions for using Bison match the practical conditions for
+using the other GNU tools.
+
+This exception applies when Bison is generating code for a parser.
+You can tell whether the exception applies to a Bison output file by
+inspecting the file for text beginning with ``As a special
+exception@dots{}''. The text spells out the exact terms of the
+exception.

+@node Language and Grammar
+@section Languages and Context-Free Grammars
+
+@cindex context-free grammar
+@cindex grammar, context-free
+In order for Bison to parse a language, it must be described by a
+@dfn{context-free grammar}. This means that you specify one or more
+@dfn{syntactic groupings} and give rules for constructing them from their
+parts. For example, in the C language, one kind of grouping is called an
+`expression'. One rule for making an expression might be, ``An expression
+can be made of a minus sign and another expression''. Another would be,
+``An expression can be an integer''. As you can see, rules are often
+recursive, but there must be at least one rule which leads out of the
+recursion.
+
+@cindex BNF
+@cindex Backus-Naur form
+The most common formal system for presenting such rules for humans to read
+is @dfn{Backus-Naur Form} or ``BNF'', which was developed in
+order to specify the language Algol 60. Any grammar expressed in
+BNF is a context-free grammar. The input to Bison is
+essentially machine-readable BNF.
+
+@cindex LALR grammars
+@cindex IELR grammars
+@cindex LR grammars
+There are various important subclasses of context-free grammars. Although
+it can handle almost all context-free grammars, Bison is optimized for what
+are called LR(1) grammars. In brief, in these grammars, it must be possible
+to tell how to parse any portion of an input string with just a single token
+of lookahead. For historical reasons, Bison by default is limited by the
+additional restrictions of LALR(1), which is hard to explain simply.
+@xref{Mysterious Conflicts}, for more information on this. As an
+experimental feature, you can escape these additional restrictions by
+requesting IELR(1) or canonical LR(1) parser tables. @xref{LR Table
+Construction}, to learn how.
+
+@cindex GLR parsing
+@cindex generalized LR (GLR) parsing
+@cindex ambiguous grammars
+@cindex nondeterministic parsing
+
+Parsers for LR(1) grammars are @dfn{deterministic}, meaning
+roughly that the next grammar rule to apply at any point in the input is
+uniquely determined by the preceding input and a fixed, finite portion
+(called a @dfn{lookahead}) of the remaining input. A context-free
+grammar can be @dfn{ambiguous}, meaning that there are multiple ways to
+apply the grammar rules to get the same inputs. Even unambiguous
+grammars can be @dfn{nondeterministic}, meaning that no fixed
+lookahead always suffices to determine the next grammar rule to apply.
+With the proper declarations, Bison is also able to parse these more
+general context-free grammars, using a technique known as GLR
+parsing (for Generalized LR). Bison's GLR parsers
+are able to handle any context-free grammar for which the number of
+possible parses of any given string is finite.
+
+@cindex symbols (abstract)
+@cindex token
+@cindex syntactic grouping
+@cindex grouping, syntactic
+In the formal grammatical rules for a language, each kind of syntactic
+unit or grouping is named by a @dfn{symbol}. Those which are built by
+grouping smaller constructs according to grammatical rules are called
+@dfn{nonterminal symbols}; those which can't be subdivided are called
+@dfn{terminal symbols} or @dfn{token types}. We call a piece of input
+corresponding to a single terminal symbol a @dfn{token}, and a piece
+corresponding to a single nonterminal symbol a @dfn{grouping}.
+
+We can use the C language as an example of what symbols, terminal and
+nonterminal, mean. The tokens of C are identifiers, constants (numeric
+and string), and the various keywords, arithmetic operators and
+punctuation marks. So the terminal symbols of a grammar for C include
+`identifier', `number', `string', plus one symbol for each keyword,
+operator or punctuation mark: `if', `return', `const', `static', `int',
+`char', `plus-sign', `open-brace', `close-brace', `comma' and many more.
+(These tokens can be subdivided into characters, but that is a matter of
+lexicography, not grammar.)
+
+Here is a simple C function subdivided into tokens:
+
+@example
+int /* @r{keyword `int'} */
+square (int x) /* @r{identifier, open-paren, keyword `int',}
+ @r{identifier, close-paren} */
+@{ /* @r{open-brace} */
+ return x * x; /* @r{keyword `return', identifier, asterisk,}
+ @r{identifier, semicolon} */
+@} /* @r{close-brace} */
+@end example
+
+The syntactic groupings of C include the expression, the statement, the
+declaration, and the function definition. These are represented in the
+grammar of C by nonterminal symbols `expression', `statement',
+`declaration' and `function definition'. The full grammar uses dozens of
+additional language constructs, each with its own nonterminal symbol, in
+order to express the meanings of these four. The example above is a
+function definition; it contains one declaration, and one statement. In
+the statement, each @samp{x} is an expression and so is @samp{x * x}.
+
+Each nonterminal symbol must have grammatical rules showing how it is made
+out of simpler constructs. For example, one kind of C statement is the
+@code{return} statement; this would be described with a grammar rule which
+reads informally as follows:
+
+@quotation
+A `statement' can be made of a `return' keyword, an `expression' and a
+`semicolon'.
+@end quotation
+
+@noindent
+There would be many other rules for `statement', one for each kind of
+statement in C.
+
+@cindex start symbol
+One nonterminal symbol must be distinguished as the special one which
+defines a complete utterance in the language. It is called the @dfn{start
+symbol}. In a compiler, this means a complete input program. In the C
+language, the nonterminal symbol `sequence of definitions and declarations'
+plays this role.
+
+For example, @samp{1 + 2} is a valid C expression---a valid part of a C
+program---but it is not valid as an @emph{entire} C program. In the
+context-free grammar of C, this follows from the fact that `expression' is
+not the start symbol.
+
+The Bison parser reads a sequence of tokens as its input, and groups the
+tokens using the grammar rules. If the input is valid, the end result is
+that the entire token sequence reduces to a single grouping whose symbol is
+the grammar's start symbol. If we use a grammar for C, the entire input
+must be a `sequence of definitions and declarations'. If not, the parser
+reports a syntax error.
+
+@node Grammar in Bison
+@section From Formal Rules to Bison Input
+@cindex Bison grammar
+@cindex grammar, Bison
+@cindex formal grammar
+
+A formal grammar is a mathematical construct. To define the language
+for Bison, you must write a file expressing the grammar in Bison syntax:
+a @dfn{Bison grammar} file. @xref{Grammar File, ,Bison Grammar Files}.
+
+A nonterminal symbol in the formal grammar is represented in Bison input
+as an identifier, like an identifier in C@. By convention, it should be
+in lower case, such as @code{expr}, @code{stmt} or @code{declaration}.
+
+The Bison representation for a terminal symbol is also called a @dfn{token
+type}. Token types as well can be represented as C-like identifiers. By
+convention, these identifiers should be upper case to distinguish them from
+nonterminals: for example, @code{INTEGER}, @code{IDENTIFIER}, @code{IF} or
+@code{RETURN}. A terminal symbol that stands for a particular keyword in
+the language should be named after that keyword converted to upper case.
+The terminal symbol @code{error} is reserved for error recovery.
+@xref{Symbols}.
+
+A terminal symbol can also be represented as a character literal, just like
+a C character constant. You should do this whenever a token is just a
+single character (parenthesis, plus-sign, etc.): use that same character in
+a literal as the terminal symbol for that token.
+
+A third way to represent a terminal symbol is with a C string constant
+containing several characters. @xref{Symbols}, for more information.
+
+The grammar rules also have an expression in Bison syntax. For example,
+here is the Bison rule for a C @code{return} statement. The semicolon in
+quotes is a literal character token, representing part of the C syntax for
+the statement; the naked semicolon, and the colon, are Bison punctuation
+used in every rule.
+
+@example
+stmt: RETURN expr ';' ;
+@end example
+
+@noindent
+@xref{Rules, ,Syntax of Grammar Rules}.
+
+@node Semantic Values
+@section Semantic Values
+@cindex semantic value
+@cindex value, semantic
+
+A formal grammar selects tokens only by their classifications: for example,
+if a rule mentions the terminal symbol `integer constant', it means that
+@emph{any} integer constant is grammatically valid in that position. The
+precise value of the constant is irrelevant to how to parse the input: if
+@samp{x+4} is grammatical then @samp{x+1} or @samp{x+3989} is equally
+grammatical.
+
+But the precise value is very important for what the input means once it is
+parsed. A compiler is useless if it fails to distinguish between 4, 1 and
+3989 as constants in the program! Therefore, each token in a Bison grammar
+has both a token type and a @dfn{semantic value}. @xref{Semantics,
+,Defining Language Semantics},
+for details.
+
+The token type is a terminal symbol defined in the grammar, such as
+@code{INTEGER}, @code{IDENTIFIER} or @code{','}. It tells everything
+you need to know to decide where the token may validly appear and how to
+group it with other tokens. The grammar rules know nothing about tokens
+except their types.
+
+The semantic value has all the rest of the information about the
+meaning of the token, such as the value of an integer, or the name of an
+identifier. (A token such as @code{','} which is just punctuation doesn't
+need to have any semantic value.)
+
+For example, an input token might be classified as token type
+@code{INTEGER} and have the semantic value 4. Another input token might
+have the same token type @code{INTEGER} but value 3989. When a grammar
+rule says that @code{INTEGER} is allowed, either of these tokens is
+acceptable because each is an @code{INTEGER}. When the parser accepts the
+token, it keeps track of the token's semantic value.
+
+Each grouping can also have a semantic value as well as its nonterminal
+symbol. For example, in a calculator, an expression typically has a
+semantic value that is a number. In a compiler for a programming
+language, an expression typically has a semantic value that is a tree
+structure describing the meaning of the expression.
+
+@node Semantic Actions
+@section Semantic Actions
+@cindex semantic actions
+@cindex actions, semantic
+
+In order to be useful, a program must do more than parse input; it must
+also produce some output based on the input. In a Bison grammar, a grammar
+rule can have an @dfn{action} made up of C statements. Each time the
+parser recognizes a match for that rule, the action is executed.
+@xref{Actions}.
+
+Most of the time, the purpose of an action is to compute the semantic value
+of the whole construct from the semantic values of its parts. For example,
+suppose we have a rule which says an expression can be the sum of two
+expressions. When the parser recognizes such a sum, each of the
+subexpressions has a semantic value which describes how it was built up.
+The action for this rule should create a similar sort of value for the
+newly recognized larger expression.
+
+For example, here is a rule that says an expression can be the sum of
+two subexpressions:
+
+@example
+expr: expr '+' expr @{ $$ = $1 + $3; @} ;
+@end example
+
+@noindent
+The action says how to produce the semantic value of the sum expression

+@cindex conflicts
+@cindex shift/reduce conflicts
+@cindex reduce/reduce conflicts
+
+In some grammars, Bison's deterministic
+LR(1) parsing algorithm cannot decide whether to apply a
+certain grammar rule at a given point. That is, it may not be able to
+decide (on the basis of the input read so far) which of two possible
+reductions (applications of a grammar rule) applies, or whether to apply
+a reduction or read more of the input and apply a reduction later in the
+input. These are known respectively as @dfn{reduce/reduce} conflicts
+(@pxref{Reduce/Reduce}), and @dfn{shift/reduce} conflicts
+(@pxref{Shift/Reduce}).
+
+To use a grammar that is not easily modified to be LR(1), a
+more general parsing algorithm is sometimes necessary. If you include
+@code{%glr-parser} among the Bison declarations in your file
+(@pxref{Grammar Outline}), the result is a Generalized LR
+(GLR) parser. These parsers handle Bison grammars that
+contain no unresolved conflicts (i.e., after applying precedence
+declarations) identically to deterministic parsers. However, when
+faced with unresolved shift/reduce and reduce/reduce conflicts,
+GLR parsers use the simple expedient of doing both,
+effectively cloning the parser to follow both possibilities. Each of
+the resulting parsers can again split, so that at any given time, there
+can be any number of possible parses being explored. The parsers
+proceed in lockstep; that is, all of them consume (shift) a given input
+symbol before any of them proceed to the next. Each of the cloned
+parsers eventually meets one of two possible fates: either it runs into
+a parsing error, in which case it simply vanishes, or it merges with
+another parser, because the two of them have reduced the input to an
+identical set of symbols.
+
+During the time that there are multiple parsers, semantic actions are
+recorded, but not performed. When a parser disappears, its recorded
+semantic actions disappear as well, and are never performed. When a
+reduction makes two parsers identical, causing them to merge, Bison
+records both sets of semantic actions. Whenever the last two parsers
+merge, reverting to the single-parser case, Bison resolves all the
+outstanding actions either by precedences given to the grammar rules
+involved, or by performing both actions, and then calling a designated
+user-defined function on the resulting values to produce an arbitrary
+merged result.

+@subsection Using GLR on Unambiguous Grammars
+@cindex GLR parsing, unambiguous grammars
+@cindex generalized LR (GLR) parsing, unambiguous grammars
+@findex %glr-parser
+@findex %expect-rr
+@cindex conflicts
+@cindex reduce/reduce conflicts
+@cindex shift/reduce conflicts
+
+In the simplest cases, you can use the GLR algorithm
+to parse grammars that are unambiguous but fail to be LR(1).
+Such grammars typically require more than one symbol of lookahead.
+
+Consider a problem that
+arises in the declaration of enumerated and subrange types in the
+programming language Pascal. Here are some examples:
+
+@example
+type subrange = lo .. hi;
+type enum = (a, b, c);
+@end example
+
+@noindent
+The original language standard allows only numeric
+literals and constant identifiers for the subrange bounds (@samp{lo}
+and @samp{hi}), but Extended Pascal (ISO/IEC
+10206) and many other
+Pascal implementations allow arbitrary expressions there. This gives
+rise to the following situation, containing a superfluous pair of
+parentheses:
+
+@example
+type subrange = (a) .. b;
+@end example
+
+@noindent
+Compare this to the following declaration of an enumerated
+type with only one value:
+
+@example
+type enum = (a);
+@end example
+
+@noindent
+(These declarations are contrived, but they are syntactically
+valid, and more-complicated cases can come up in practical programs.)
+
+These two declarations look identical until the @samp{..} token.
+With normal LR(1) one-token lookahead it is not
+possible to decide between the two forms when the identifier
+@samp{a} is parsed. It is, however, desirable
+for a parser to decide this, since in the latter case
+@samp{a} must become a new identifier to represent the enumeration
+value, while in the former case @samp{a} must be evaluated with its
+current meaning, which may be a constant or even a function call.
+
+You could parse @samp{(a)} as an ``unspecified identifier in parentheses'',
+to be resolved later, but this typically requires substantial
+contortions in both semantic actions and large parts of the
+grammar, where the parentheses are nested in the recursive rules for
+expressions.
+
+You might think of using the lexer to distinguish between the two
+forms by returning different tokens for currently defined and
+undefined identifiers. But if these declarations occur in a local
+scope, and @samp{a} is defined in an outer scope, then both forms
+are possible---either locally redefining @samp{a}, or using the
+value of @samp{a} from the outer scope. So this approach cannot
+work.
+
+A simple solution to this problem is to declare the parser to
+use the GLR algorithm.
+When the GLR parser reaches the critical state, it
+merely splits into two branches and pursues both syntax rules
+simultaneously. Sooner or later, one of them runs into a parsing
+error. If there is a @samp{..} token before the next
+@samp{;}, the rule for enumerated types fails since it cannot
+accept @samp{..} anywhere; otherwise, the subrange type rule
+fails since it requires a @samp{..} token. So one of the branches
+fails silently, and the other one continues normally, performing
+all the intermediate actions that were postponed during the split.
+
+If the input is syntactically incorrect, both branches fail and the parser
+reports a syntax error as usual.
+
+The effect of all this is that the parser seems to ``guess'' the
+correct branch to take, or in other words, it seems to use more
+lookahead than the underlying LR(1) algorithm actually allows
+for. In this example, LR(2) would suffice, but also some cases
+that are not LR(@math{k}) for any @math{k} can be handled this way.
+
+In general, a GLR parser can take quadratic or cubic worst-case time,
+and the current Bison parser even takes exponential time and space
+for some grammars. In practice, this rarely happens, and for many
+grammars it is possible to prove that it cannot happen.
+The present example contains only one conflict between two
+rules, and the type-declaration context containing the conflict
+cannot be nested. So the number of
+branches that can exist at any time is limited by the constant 2,
+and the parsing time is still linear.
+
+Here is a Bison grammar corresponding to the example above. It
+parses a vastly simplified form of Pascal type declarations.
+
+@example
+%token TYPE DOTDOT ID
+
+@group
+%left '+' '-'
+%left '*' '/'
+@end group
+
+%%
+
+@group
+type_decl: TYPE ID '=' type ';' ;
+@end group
+
+@group
+type:
+ '(' id_list ')'
+| expr DOTDOT expr
+;
+@end group
+
+@group
+id_list:
+ ID
+| id_list ',' ID
+;
+@end group
+
+@group
+expr:
+ '(' expr ')'
+| expr '+' expr
+| expr '-' expr
+| expr '*' expr
+| expr '/' expr
+| ID
+;
+@end group
+@end example
+
+When used as a normal LR(1) grammar, Bison correctly complains
+about one reduce/reduce conflict. In the conflicting situation the
+parser chooses one of the alternatives, arbitrarily the one
+declared first. Therefore the following correct input is not
+recognized:
+
+@example
+type t = (a) .. b;
+@end example
+
+The parser can be turned into a GLR parser, while also telling Bison
+to be silent about the one known reduce/reduce conflict, by adding
+these two declarations to the Bison grammar file (before the first
+@samp{%%}):
+
+@example
+%glr-parser
+%expect-rr 1
+@end example
+
+@noindent
+No change in the grammar itself is required. Now the
+parser recognizes all valid declarations, according to the
+limited syntax above, transparently. In fact, the user does not even
+notice when the parser splits.
+
+So here we have a case where we can use the benefits of GLR,
+almost without disadvantages. Even in simple cases like this, however,
+there are at least two potential problems to beware. First, always
+analyze the conflicts reported by Bison to make sure that GLR
+splitting is only done where it is intended. A GLR parser
+splitting inadvertently may cause problems less obvious than an
+LR parser statically choosing the wrong alternative in a
+conflict. Second, consider interactions with the lexer (@pxref{Semantic
+Tokens}) with great care. Since a split parser consumes tokens without
+performing any actions during the split, the lexer cannot obtain
+information via parser actions. Some cases of lexer interactions can be
+eliminated by using GLR to shift the complications from the
+lexer to the parser. You must check the remaining cases for
+correctness.
+
+In our example, it would be safe for the lexer to return tokens based on
+their current meanings in some symbol table, because no new symbols are
+defined in the middle of a type declaration. Though it is possible for
+a parser to define the enumeration constants as they are parsed, before
+the type declaration is completed, it actually makes no difference since
+they cannot be used within the same enumerated type declaration.

+@cindex generalized LR (GLR) parsing, ambiguous grammars
+@findex %dprec
+@findex %merge
+@cindex conflicts
+@cindex reduce/reduce conflicts
+
+Let's consider an example, vastly simplified from a C++ grammar.
+
+@example
+%@{
+ #include <stdio.h>
+ #define YYSTYPE char const *
+ int yylex (void);
+ void yyerror (char const *);
+%@}
+
+%token TYPENAME ID
+

+
+%glr-parser
+
+%%
+
+prog:
+ /* Nothing. */
+| prog stmt @{ printf ("\n"); @}
+;
+
+stmt:
+ expr ';' %dprec 1
+| decl %dprec 2
+;
+
+expr:
+ ID @{ printf ("%s ", $$); @}
+| TYPENAME '(' expr ')'
+ @{ printf ("%s <cast> ", $1); @}
+| expr '+' expr @{ printf ("+ "); @}
+| expr '=' expr @{ printf ("= "); @}
+;
+
+decl:
+ TYPENAME declarator ';'
+ @{ printf ("%s <declare> ", $1); @}
+| TYPENAME declarator '=' expr ';'
+ @{ printf ("%s <init-declare> ", $1); @}
+;
+
+declarator:
+ ID @{ printf ("\"%s\" ", $1); @}
+| '(' declarator ')'
+;
+@end example
+
+@noindent
+This models a problematic part of the C++ grammar---the ambiguity between
+certain declarations and statements. For example,
+
+@example
+T (x) = y+z;
+@end example
+
+@noindent
+parses as either an @code{expr} or a @code{stmt}
+(assuming that @samp{T} is recognized as a @code{TYPENAME} and
+@samp{x} as an @code{ID}).
+Bison detects this as a reduce/reduce conflict between the rules
+@code{expr : ID} and @code{declarator : ID}, which it cannot resolve at the
+time it encounters @code{x} in the example above. Since this is a
+GLR parser, it therefore splits the problem into two parses, one for
+each choice of resolving the reduce/reduce conflict.
+Unlike the example from the previous section (@pxref{Simple GLR Parsers}),
+however, neither of these parses ``dies,'' because the grammar as it stands is
+ambiguous. One of the parsers eventually reduces @code{stmt : expr ';'} and
+the other reduces @code{stmt : decl}, after which both parsers are in an
+identical state: they've seen @samp{prog stmt} and have the same unprocessed
+input remaining. We say that these parses have @dfn{merged.}
+
+At this point, the GLR parser requires a specification in the
+grammar of how to choose between the competing parses.
+In the example above, the two @code{%dprec}
+declarations specify that Bison is to give precedence
+to the parse that interprets the example as a
+@code{decl}, which implies that @code{x} is a declarator.
+The parser therefore prints
+
+@example
+"x" y z + T <init-declare>
+@end example
+
+The @code{%dprec} declarations only come into play when more than one
+parse survives. Consider a different input string for this parser:
+
+@example
+T (x) + y;
+@end example
+
+@noindent
+This is another example of using GLR to parse an unambiguous
+construct, as shown in the previous section (@pxref{Simple GLR Parsers}).
+Here, there is no ambiguity (this cannot be parsed as a declaration).
+However, at the time the Bison parser encounters @code{x}, it does not
+have enough information to resolve the reduce/reduce conflict (again,
+between @code{x} as an @code{expr} or a @code{declarator}). In this
+case, no precedence declaration is used. Again, the parser splits
+into two, one assuming that @code{x} is an @code{expr}, and the other
+assuming @code{x} is a @code{declarator}. The second of these parsers
+then vanishes when it sees @code{+}, and the parser prints
+
+@example
+x T <cast> y +
+@end example
+
+Suppose that instead of resolving the ambiguity, you wanted to see all
+the possibilities. For this purpose, you must merge the semantic
+actions of the two possible parsers, rather than choosing one over the
+other. To do so, you could change the declaration of @code{stmt} as
+follows:
+
+@example
+stmt:
+ expr ';' %merge <stmtMerge>
+| decl %merge <stmtMerge>
+;
+@end example
+
+@noindent
+and define the @code{stmtMerge} function as:
+
+@example
+static YYSTYPE
+stmtMerge (YYSTYPE x0, YYSTYPE x1)
+@{
+ printf ("<OR> ");
+ return "";
+@}
+@end example
+
+@noindent
+with an accompanying forward declaration
+in the C declarations at the beginning of the file:
+
+@example
+%@{
+ #define YYSTYPE char const *
+ static YYSTYPE stmtMerge (YYSTYPE x0, YYSTYPE x1);
+%@}
+@end example
+
+@noindent
+With these declarations, the resulting parser parses the first example
+as both an @code{expr} and a @code{decl}, and prints
+
+@example
+"x" y z + T <init-declare> x T <cast> y z + = <OR>
+@end example
+
+Bison requires that all of the
+productions that participate in any particular merge have identical
+@samp{%merge} clauses. Otherwise, the ambiguity would be unresolvable,
+and the parser will report an error during any parse that results in
+the offending merge.
+
+@node GLR Semantic Actions
+@subsection GLR Semantic Actions
+
+@cindex deferred semantic actions
+By definition, a deferred semantic action is not performed at the same time as
+the associated reduction.
+This raises caveats for several Bison features you might use in a semantic
+action in a GLR parser.
+
+@vindex yychar
+@cindex GLR parsers and @code{yychar}
+@vindex yylval
+@cindex GLR parsers and @code{yylval}
+@vindex yylloc
+@cindex GLR parsers and @code{yylloc}
+In any semantic action, you can examine @code{yychar} to determine the type of
+the lookahead token present at the time of the associated reduction.
+After checking that @code{yychar} is not set to @code{YYEMPTY} or @code{YYEOF},
+you can then examine @code{yylval} and @code{yylloc} to determine the
+lookahead token's semantic value and location, if any.
+In a nondeferred semantic action, you can also modify any of these variables to
+influence syntax analysis.
+@xref{Lookahead, ,Lookahead Tokens}.
+
+@findex yyclearin
+@cindex GLR parsers and @code{yyclearin}
+In a deferred semantic action, it's too late to influence syntax analysis.
+In this case, @code{yychar}, @code{yylval}, and @code{yylloc} are set to
+shallow copies of the values they had at the time of the associated reduction.
+For this reason alone, modifying them is dangerous.
+Moreover, the result of modifying them is undefined and subject to change with
+future versions of Bison.
+For example, if a semantic action might be deferred, you should never write it
+to invoke @code{yyclearin} (@pxref{Action Features}) or to attempt to free
+memory referenced by @code{yylval}.
+
+@findex YYERROR
+@cindex GLR parsers and @code{YYERROR}
+Another Bison feature requiring special consideration is @code{YYERROR}
+(@pxref{Action Features}), which you can invoke in a semantic action to
+initiate error recovery.
+During deterministic GLR operation, the effect of @code{YYERROR} is
+the same as its effect in a deterministic parser.
+In a deferred semantic action, its effect is undefined.
+@c The effect is probably a syntax error at the split point.
+
+Also, see @ref{Location Default Action, ,Default Action for Locations}, which
+describes a special usage of @code{YYLLOC_DEFAULT} in GLR parsers.
+
+@node Compiler Requirements
+@subsection Considerations when Compiling GLR Parsers
+@cindex @code{inline}
+@cindex GLR parsers and @code{inline}
+
+The GLR parsers require a compiler for ISO C89 or
+later. In addition, they use the @code{inline} keyword, which is not
+C89, but is C99 and is a common extension in pre-C99 compilers. It is
+up to the user of these parsers to handle
+portability issues. For instance, if using Autoconf and the Autoconf
+macro @code{AC_C_INLINE}, a mere
+
+@example
+%@{
+ #include <config.h>
+%@}
+@end example
+
+@noindent
+will suffice. Otherwise, we suggest
+
+@example
+%@{
+ #if (__STDC_VERSION__ < 199901 && ! defined __GNUC__ \
+ && ! defined inline)
+ # define inline
+ #endif
+%@}
+@end example
+
+@node Locations
+@section Locations
+@cindex location
+@cindex textual location
+@cindex location, textual
+
+Many applications, like interpreters or compilers, have to produce verbose
+and useful error messages. To achieve this, one must be able to keep track of
+the @dfn{textual location}, or @dfn{location}, of each syntactic construct.
+Bison provides a mechanism for handling these locations.
+
+Each token has a semantic value. In a similar fashion, each token has an
+associated location, but the type of locations is the same for all tokens
+and groupings. Moreover, the output parser is equipped with a default data
+structure for storing locations (@pxref{Tracking Locations}, for more
+details).
+
+Like semantic values, locations can be reached in actions using a dedicated
+set of constructs. In the example above, the location of the whole grouping
+is @code{@@$}, while the locations of the subexpressions are @code{@@1} and
+@code{@@3}.
+
+When a rule is matched, a default action is used to compute the semantic value
+of its left hand side (@pxref{Actions}). In the same way, another default
+action is used for locations. However, the action for locations is general
+enough for most cases, meaning there is usually no need to describe for each
+rule how @code{@@$} should be formed. When building a new location for a given
+grouping, the default behavior of the output parser is to take the beginning
+of the first symbol, and the end of the last symbol.
+
+@node Bison Parser
+@section Bison Output: the Parser Implementation File
+@cindex Bison parser
+@cindex Bison utility
+@cindex lexical analyzer, purpose
+@cindex parser
+
+When you run Bison, you give it a Bison grammar file as input. The
+most important output is a C source file that implements a parser for
+the language described by the grammar. This parser is called a
+@dfn{Bison parser}, and this file is called a @dfn{Bison parser
+implementation file}. Keep in mind that the Bison utility and the
+Bison parser are two distinct programs: the Bison utility is a program
+whose output is the Bison parser implementation file that becomes part
+of your program.
+
+The job of the Bison parser is to group tokens into groupings according to
+the grammar rules---for example, to build identifiers and operators into
+expressions. As it does this, it runs the actions for the grammar rules it
+uses.
+
+The tokens come from a function called the @dfn{lexical analyzer} that
+you must supply in some fashion (such as by writing it in C). The Bison
+parser calls the lexical analyzer each time it wants a new token. It
+doesn't know what is ``inside'' the tokens (though their semantic values
+may reflect this). Typically the lexical analyzer makes the tokens by
+parsing characters of text, but Bison does not depend on this.
+@xref{Lexical, ,The Lexical Analyzer Function @code{yylex}}.
+
+The Bison parser implementation file is C code which defines a
+function named @code{yyparse} which implements that grammar. This
+function does not make a complete C program: you must supply some
+additional functions. One is the lexical analyzer. Another is an
+error-reporting function which the parser calls to report an error.
+In addition, a complete C program must start with a function called
+@code{main}; you have to provide this, and arrange for it to call
+@code{yyparse} or the parser will never run. @xref{Interface, ,Parser
+C-Language Interface}.
+
+Aside from the token type names and the symbols in the actions you
+write, all symbols defined in the Bison parser implementation file
+itself begin with @samp{yy} or @samp{YY}. This includes interface
+functions such as the lexical analyzer function @code{yylex}, the
+error reporting function @code{yyerror} and the parser function
+@code{yyparse} itself. This also includes numerous identifiers used
+for internal purposes. Therefore, you should avoid using C
+identifiers starting with @samp{yy} or @samp{YY} in the Bison grammar
+file except for the ones defined in this manual. Also, you should
+avoid using the C identifiers @samp{malloc} and @samp{free} for
+anything other than their usual meanings.
+
+In some cases the Bison parser implementation file includes system
+headers, and in those cases your code should respect the identifiers
+reserved by those headers. On some non-GNU hosts, @code{<alloca.h>},
+@code{<malloc.h>}, @code{<stddef.h>}, and @code{<stdlib.h>} are
+included as needed to declare memory allocators and related types.
+@code{<libintl.h>} is included if message translation is in use
+(@pxref{Internationalization}). Other system headers may be included
+if you define @code{YYDEBUG} to a nonzero value (@pxref{Tracing,
+,Tracing Your Parser}).

+The @samp{%%}, @samp{%@{} and @samp{%@}} are punctuation that appears

+
+The prologue may define types and variables used in the actions. You can
+also use preprocessor commands to define macros used there, and use
+@code{#include} to include header files that do any of these things.
+You need to declare the lexical analyzer @code{yylex} and the error
+printer @code{yyerror} here, along with any other global identifiers
+used by the actions in the grammar rules.
+
+The Bison declarations declare the names of the terminal and nonterminal
+symbols, and may also describe operator precedence and the data types of
+semantic values of various symbols.
+
+The grammar rules define how to construct each nonterminal symbol from its
+parts.

+The epilogue can contain any code you want to use. Often the

+@end example
+
+The declarations section (@pxref{Prologue, , The prologue}) contains two
+preprocessor directives and two forward declarations.
+
+The @code{#define} directive defines the macro @code{YYSTYPE}, thus
+specifying the C data type for semantic values of both tokens and
+groupings (@pxref{Value Type, ,Data Types of Semantic Values}). The
+Bison parser will use whatever type @code{YYSTYPE} is defined as; if you
+don't define it, @code{int} is the default. Because we specify
+@code{double}, each token and each expression has an associated value,
+which is a floating point number.
+
+The @code{#include} directive is used to declare the exponentiation
+function @code{pow}.
+
+The forward declarations for @code{yylex} and @code{yyerror} are
+needed because the C language requires that functions be declared
+before they are used. These functions will be defined in the
+epilogue, but the parser calls them so they must be declared in the
+prologue.
+
+The second section, Bison declarations, provides information to Bison
+about the token types (@pxref{Bison Declarations, ,The Bison
+Declarations Section}). Each terminal symbol that is not a
+single-character literal must be declared here. (Single-character
+literals normally don't need to be declared.) In this example, all the
+arithmetic operators are designated by single-character literals, so the
+only terminal symbol that needs to be declared is @code{NUM}, the token
+type for numeric constants.
+
+@node Rpcalc Rules
+@subsection Grammar Rules for @code{rpcalc}
+
+Here are the grammar rules for the reverse polish notation calculator.
+
+@example
+@group
+input:
+ /* empty */
+| input line
+;
+@end group
+
+@group
+line:
+ '\n'
+| exp '\n' @{ printf ("%.10g\n", $1); @}
+;
+@end group
+
+@group
+exp:
+ NUM @{ $$ = $1; @}
+| exp exp '+' @{ $$ = $1 + $2; @}
+| exp exp '-' @{ $$ = $1 - $2; @}
+| exp exp '*' @{ $$ = $1 * $2; @}
+| exp exp '/' @{ $$ = $1 / $2; @}
+| exp exp '^' @{ $$ = pow ($1, $2); @} /* Exponentiation */
+| exp 'n' @{ $$ = -$1; @} /* Unary minus */
+;
+@end group
+%%
+@end example
+
+The groupings of the rpcalc ``language'' defined here are the expression
+(given the name @code{exp}), the line of input (@code{line}), and the
+complete input transcript (@code{input}). Each of these nonterminal
+symbols has several alternate rules, joined by the vertical bar @samp{|}
+which is read as ``or''. The following sections explain what these rules
+mean.
+
+The semantics of the language is determined by the actions taken when a
+grouping is recognized. The actions are the C code that appears inside
+braces. @xref{Actions}.
+
+You must specify these actions in C, but Bison provides the means for
+passing semantic values between the rules. In each action, the
+pseudo-variable @code{$$} stands for the semantic value for the grouping
+that the rule is going to construct. Assigning a value to @code{$$} is the
+main job of most actions. The semantic values of the components of the
+rule are referred to as @code{$1}, @code{$2}, and so on.

+
+@node Rpcalc Input
+@subsubsection Explanation of @code{input}
+
+Consider the definition of @code{input}:
+
+@example
+input:
+ /* empty */
+| input line
+;
+@end example
+
+This definition reads as follows: ``A complete input is either an empty
+string, or a complete input followed by an input line''. Notice that
+``complete input'' is defined in terms of itself. This definition is said
+to be @dfn{left recursive} since @code{input} appears always as the
+leftmost symbol in the sequence. @xref{Recursion, ,Recursive Rules}.
+
+The first alternative is empty because there are no symbols between the
+colon and the first @samp{|}; this means that @code{input} can match an
+empty string of input (no tokens). We write the rules this way because it
+is legitimate to type @kbd{Ctrl-d} right after you start the calculator.
+It's conventional to put an empty alternative first and write the comment
+@samp{/* empty */} in it.
+
+The second alternate rule (@code{input line}) handles all nontrivial input.
+It means, ``After reading any number of lines, read one more line if
+possible.'' The left recursion makes this rule into a loop. Since the
+first alternative matches empty input, the loop can be executed zero or
+more times.
+
+The parser function @code{yyparse} continues to process input until a
+grammatical error is seen or the lexical analyzer says there are no more
+input tokens; we will arrange for the latter to happen at end-of-input.
+
+@node Rpcalc Line
+@subsubsection Explanation of @code{line}
+
+Now consider the definition of @code{line}:
+
+@example
+line:
+ '\n'
+| exp '\n' @{ printf ("%.10g\n", $1); @}
+;
+@end example
+
+The first alternative is a token which is a newline character; this means
+that rpcalc accepts a blank line (and ignores it, since there is no
+action). The second alternative is an expression followed by a newline.
+This is the alternative that makes rpcalc useful. The semantic value of
+the @code{exp} grouping is the value of @code{$1} because the @code{exp} in
+question is the first symbol in the alternative. The action prints this
+value, which is the result of the computation the user asked for.
+
+This action is unusual because it does not assign a value to @code{$$}. As
+a consequence, the semantic value associated with the @code{line} is
+uninitialized (its value will be unpredictable). This would be a bug if
+that value were ever used, but we don't use it: once rpcalc has printed the
+value of the user's input line, that value is no longer needed.
+
+@node Rpcalc Expr
+@subsubsection Explanation of @code{expr}
+
+The @code{exp} grouping has several rules, one for each kind of expression.
+The first rule handles the simplest expressions: those that are just numbers.
+The second handles an addition-expression, which looks like two expressions
+followed by a plus-sign. The third handles subtraction, and so on.
+
+@example
+exp:
+ NUM
+| exp exp '+' @{ $$ = $1 + $2; @}
+| exp exp '-' @{ $$ = $1 - $2; @}
+@dots{}
+;
+@end example
+
+We have used @samp{|} to join all the rules for @code{exp}, but we could
+equally well have written them separately:
+
+@example
+exp: NUM ;
+exp: exp exp '+' @{ $$ = $1 + $2; @};
+exp: exp exp '-' @{ $$ = $1 - $2; @};
+@dots{}
+@end example
+
+Most of the rules have actions that compute the value of the expression in
+terms of the value of its parts. For example, in the rule for addition,
+@code{$1} refers to the first component @code{exp} and @code{$2} refers to
+the second one. The third component, @code{'+'}, has no meaningful
+associated semantic value, but if it had one you could refer to it as
+@code{$3}. When @code{yyparse} recognizes a sum expression using this
+rule, the sum of the two subexpressions' values is produced as the value of
+the entire expression. @xref{Actions}.
+
+You don't have to give an action for every rule. When a rule has no
+action, Bison by default copies the value of @code{$1} into @code{$$}.
+This is what happens in the first rule (the one that uses @code{NUM}).
+
+The formatting shown here is the recommended convention, but Bison does
+not require it. You can add or change white space as much as you wish.
+For example, this:
+
+@example
+exp: NUM | exp exp '+' @{$$ = $1 + $2; @} | @dots{} ;
+@end example
+
+@noindent
+means the same thing as this:
+
+@example
+exp:
+ NUM
+| exp exp '+' @{ $$ = $1 + $2; @}
+| @dots{}
+;
+@end example
+
+@noindent
+The latter, however, is much more readable.
+
+@node Rpcalc Lexer
+@subsection The @code{rpcalc} Lexical Analyzer
+@cindex writing a lexical analyzer
+@cindex lexical analyzer, writing
+
+The lexical analyzer's job is low-level parsing: converting characters
+or sequences of characters into tokens. The Bison parser gets its
+tokens by calling the lexical analyzer. @xref{Lexical, ,The Lexical
+Analyzer Function @code{yylex}}.
+
+Only a simple lexical analyzer is needed for the RPN
+calculator. This
+lexical analyzer skips blanks and tabs, then reads in numbers as
+@code{double} and returns them as @code{NUM} tokens. Any other character
+that isn't part of a number is a separate token. Note that the token-code
+for such a single-character token is the character itself.
+
+The return value of the lexical analyzer function is a numeric code which
+represents a token type. The same text used in Bison rules to stand for
+this token type is also a C expression for the numeric code for the type.
+This works in two ways. If the token type is a character literal, then its
+numeric code is that of the character; you can use the same
+character literal in the lexical analyzer to express the number. If the
+token type is an identifier, that identifier is defined by Bison as a C
+macro whose definition is the appropriate number. In this example,
+therefore, @code{NUM} becomes a macro for @code{yylex} to use.
+
+The semantic value of the token (if it has one) is stored into the
+global variable @code{yylval}, which is where the Bison parser will look
+for it. (The C data type of @code{yylval} is @code{YYSTYPE}, which was
+defined at the beginning of the grammar; @pxref{Rpcalc Declarations,
+,Declarations for @code{rpcalc}}.)
+
+A token type code of zero is returned if the end-of-input is encountered.
+(Bison recognizes any nonpositive value as indicating end-of-input.)
+
+Here is the code for the lexical analyzer:
+
+@example
+@group
+/* The lexical analyzer returns a double floating point
+ number on the stack and the token NUM, or the numeric code
+ of the character read if not a number. It skips all blanks
+ and tabs, and returns 0 for end-of-input. */
+
+#include <ctype.h>
+@end group
+
+@group
+int
+yylex (void)
+@{
+ int c;
+
+ /* Skip white space. */
+ while ((c = getchar ()) == ' ' || c == '\t')
+ continue;
+@end group
+@group
+ /* Process numbers. */
+ if (c == '.' || isdigit (c))
+ @{
+ ungetc (c, stdin);
+ scanf ("%lf", &yylval);
+ return NUM;
+ @}
+@end group
+@group
+ /* Return end-of-input. */

+ return 0;
+ /* Return a single char. */

+
+@node Rpcalc Main
+@subsection The Controlling Function
+@cindex controlling function
+@cindex main function in simple example
+
+In keeping with the spirit of this example, the controlling function is
+kept to the bare minimum. The only requirement is that it call
+@code{yyparse} to start the process of parsing.
+
+@example
+@group
+int
+main (void)
+@{
+ return yyparse ();
+@}
+@end group
+@end example
+
+@node Rpcalc Error
+@subsection The Error Reporting Routine
+@cindex error reporting routine
+
+When @code{yyparse} detects a syntax error, it calls the error reporting
+function @code{yyerror} to print an error message (usually but not
+always @code{"syntax error"}). It is up to the programmer to supply
+@code{yyerror} (@pxref{Interface, ,Parser C-Language Interface}), so
+here is the definition we will use:
+
+@example
+@group
+#include <stdio.h>
+@end group
+
+@group
+/* Called by yyparse on error. */
+void
+yyerror (char const *s)
+@{
+ fprintf (stderr, "%s\n", s);
+@}
+@end group
+@end example
+
+After @code{yyerror} returns, the Bison parser may recover from the error
+and continue parsing if the grammar contains a suitable error rule
+(@pxref{Error Recovery}). Otherwise, @code{yyparse} returns nonzero. We
+have not written any error rules in this example, so any invalid input will
+cause the calculator program to exit. This is not clean behavior for a
+real calculator, but it is adequate for the first example.
+
+@node Rpcalc Generate
+@subsection Running Bison to Make the Parser
+@cindex running Bison (introduction)
+
+Before running Bison to produce a parser, we need to decide how to
+arrange all the source code in one or more source files. For such a
+simple example, the easiest thing is to put everything in one file,
+the grammar file. The definitions of @code{yylex}, @code{yyerror} and
+@code{main} go at the end, in the epilogue of the grammar file
+(@pxref{Grammar Layout, ,The Overall Layout of a Bison Grammar}).
+
+For a large project, you would probably have several source files, and use
+@code{make} to arrange to recompile them.
+
+With all the source in the grammar file, you use the following command
+to convert it into a parser implementation file:
+
+@example
+bison @var{file}.y
+@end example
+
+@noindent
+In this example, the grammar file is called @file{rpcalc.y} (for
+``Reverse Polish @sc{calc}ulator''). Bison produces a parser
+implementation file named @file{@var{file}.tab.c}, removing the
+@samp{.y} from the grammar file name. The parser implementation file
+contains the source code for @code{yyparse}. The additional functions
+in the grammar file (@code{yylex}, @code{yyerror} and @code{main}) are
+copied verbatim to the parser implementation file.
+
+@node Rpcalc Compile
+@subsection Compiling the Parser Implementation File
+@cindex compiling the parser
+
+Here is how to compile and run the parser implementation file:
+
+@example
+@group
+# @r{List files in current directory.}
+$ @kbd{ls}
+rpcalc.tab.c rpcalc.y
+@end group
+
+@group
+# @r{Compile the Bison parser.}
+# @r{@samp{-lm} tells compiler to search math library for @code{pow}.}
+$ @kbd{cc -lm -o rpcalc rpcalc.tab.c}
+@end group
+
+@group
+# @r{List files again.}
+$ @kbd{ls}
+rpcalc rpcalc.tab.c rpcalc.y
+@end group

+
+The file @file{rpcalc} now contains the executable code. Here is an

+;
+@end group
+%%
+@end example
+
+@noindent
+The functions @code{yylex}, @code{yyerror} and @code{main} can be the
+same as before.
+
+There are two important new features shown in this code.
+
+In the second section (Bison declarations), @code{%left} declares token
+types and says they are left-associative operators. The declarations
+@code{%left} and @code{%right} (right associativity) take the place of
+@code{%token} which is used to declare a token type name without
+associativity. (These tokens are single-character literals, which
+ordinarily don't need to be declared. We declare them here to specify
+the associativity.)
+
+Operator precedence is determined by the line ordering of the
+declarations; the higher the line number of the declaration (lower on
+the page or screen), the higher the precedence. Hence, exponentiation
+has the highest precedence, unary minus (@code{NEG}) is next, followed
+by @samp{*} and @samp{/}, and so on. @xref{Precedence, ,Operator
+Precedence}.
+
+The other important new feature is the @code{%prec} in the grammar
+section for the unary minus operator. The @code{%prec} simply instructs
+Bison that the rule @samp{| '-' exp} has the same precedence as
+@code{NEG}---in this case the next-to-highest. @xref{Contextual
+Precedence, ,Context-Dependent Precedence}.
+
+Here is a sample run of @file{calc.y}:
+
+@need 500
+@example
+$ @kbd{calc}
+@kbd{4 + 4.5 - (34/(8*3+-3))}

+@kbd{3 ^ 2}

+@end example
+
+@node Simple Error Recovery
+@section Simple Error Recovery
+@cindex error recovery, simple
+
+Up to this point, this manual has not addressed the issue of @dfn{error
+recovery}---how to continue parsing after the parser detects a syntax
+error. All we have handled is error reporting with @code{yyerror}.
+Recall that by default @code{yyparse} returns after calling
+@code{yyerror}. This means that an erroneous input line causes the
+calculator program to exit. Now we show how to rectify this deficiency.
+
+The Bison language itself includes the reserved word @code{error}, which
+may be included in the grammar rules. In the example below it has
+been added to one of the alternatives for @code{line}:
+
+@example
+@group
+line:
+ '\n'
+| exp '\n' @{ printf ("\t%.10g\n", $1); @}
+| error '\n' @{ yyerrok; @}
+;
+@end group
+@end example
+
+This addition to the grammar allows for simple error recovery in the
+event of a syntax error. If an expression that cannot be evaluated is
+read, the error will be recognized by the third rule for @code{line},
+and parsing will continue. (The @code{yyerror} function is still called
+upon to print its message as well.) The action executes the statement
+@code{yyerrok}, a macro defined automatically by Bison; its meaning is
+that error recovery is complete (@pxref{Error Recovery}). Note the
+difference between @code{yyerrok} and @code{yyerror}; neither one is a
+misprint.
+
+This form of error recovery deals with syntax errors. There are other
+kinds of errors; for example, division by zero, which raises an exception
+signal that is normally fatal. A real calculator program must handle this
+signal and use @code{longjmp} to return to @code{main} and resume parsing
+input lines; it would also have to discard the rest of the current line of
+input. We won't discuss this issue further because it is not specific to
+Bison programs.

+Whether handling locations or not has no effect on the syntax of your

+
+Here, we will use locations to report divisions by zero, and locate the
+wrong expressions or subexpressions.

+| input line
+;

+

+@end group
+@end example
+
+This code shows how to reach locations inside of semantic actions, by
+using the pseudo-variables @code{@@@var{n}} for rule components, and the
+pseudo-variable @code{@@$} for groupings.
+
+We don't need to assign a value to @code{@@$}: the output parser does it
+automatically. By default, before executing the C code of each action,
+@code{@@$} is set to range from the beginning of @code{@@1} to the end
+of @code{@@@var{n}}, for a rule with @var{n} components. This behavior
+can be redefined (@pxref{Location Default Action, , Default Action for
+Locations}), and for very specific rules, @code{@@$} can be computed by
+hand.
+
+@node Ltcalc Lexer
+@subsection The @code{ltcalc} Lexical Analyzer.
+
+Until now, we relied on Bison's defaults to enable location
+tracking. The next step is to rewrite the lexical analyzer, and make it
+able to feed the parser with the token locations, as it already does for
+semantic values.
+
+To this end, we must take into account every single character of the
+input text, to avoid the computed locations of being fuzzy or wrong:
+
+@example
+@group
+int
+yylex (void)
+@{
+ int c;
+@end group
+
+@group
+ /* Skip white space. */
+ while ((c = getchar ()) == ' ' || c == '\t')
+ ++yylloc.last_column;
+@end group
+
+@group
+ /* Step. */
+ yylloc.first_line = yylloc.last_line;
+ yylloc.first_column = yylloc.last_column;
+@end group
+
+@group
+ /* Process numbers. */
+ if (isdigit (c))
+ @{
+ yylval = c - '0';
+ ++yylloc.last_column;
+ while (isdigit (c = getchar ()))
+ @{
+ ++yylloc.last_column;
+ yylval = yylval * 10 + c - '0';
+ @}
+ ungetc (c, stdin);
+ return NUM;
+ @}
+@end group
+
+ /* Return end-of-input. */
+ if (c == EOF)
+ return 0;
+
+@group
+ /* Return a single char, and update location. */
+ if (c == '\n')
+ @{
+ ++yylloc.last_line;
+ yylloc.last_column = 0;
+ @}
+ else
+ ++yylloc.last_column;
+ return c;
+@}
+@end group
+@end example
+
+Basically, the lexical analyzer performs the same processing as before:
+it skips blanks and tabs, and reads numbers or single-character tokens.
+In addition, it updates @code{yylloc}, the global variable (of type
+@code{YYLTYPE}) containing the token's location.
+
+Now, each time this function returns a token, the parser has its number
+as well as its semantic value, and its location in the text. The last
+needed change is to initialize @code{yylloc}, for example in the
+controlling function:
+
+@example
+@group
+int
+main (void)
+@{
+ yylloc.first_line = yylloc.last_line = 1;
+ yylloc.first_column = yylloc.last_column = 0;
+ return yyparse ();
+@}
+@end group
+@end example
+
+Remember that computing locations is not a matter of syntax. Every
+character must be associated to a location update, whether it is in

+@cindex calculator, multi-function
+
+Now that the basics of Bison have been discussed, it is time to move on to
+a more advanced problem. The above calculators provided only five
+functions, @samp{+}, @samp{-}, @samp{*}, @samp{/} and @samp{^}. It would
+be nice to have a calculator that provides other mathematical functions such
+as @code{sin}, @code{cos}, etc.
+
+It is easy to add new operators to the infix calculator as long as they are
+only single-character literals. The lexical analyzer @code{yylex} passes
+back all nonnumeric characters as tokens, so new grammar rules suffice for
+adding a new operator. But we want something more flexible: built-in
+functions whose syntax has this form:
+
+@example
+@var{function_name} (@var{argument})
+@end example
+
+@noindent
+At the same time, we will add memory to the calculator, by allowing you
+to create named variables, store values in them, and use them later.
+Here is a sample session with the multi-function calculator:
+
+@example
+$ @kbd{mfcalc}
+@kbd{pi = 3.141592653589}
+3.1415926536
+@kbd{sin(pi)}
+0.0000000000
+@kbd{alpha = beta1 = 2.3}
+2.3000000000
+@kbd{alpha}
+2.3000000000
+@kbd{ln(alpha)}
+0.8329091229
+@kbd{exp(ln(beta1))}
+2.3000000000
+$
+@end example
+
+Note that multiple assignment and nested function calls are permitted.

+
+@comment file: mfcalc.y: 1

+ #include <math.h> /* For math functions, cos(), sin(), etc. */

+%right '^' /* exponentiation */
+@end group
+@end example
+
+The above grammar introduces only two new features of the Bison language.
+These features allow semantic values to have various data types
+(@pxref{Multiple Types, ,More Than One Value Type}).
+
+The @code{%union} declaration specifies the entire list of possible types;
+this is instead of defining @code{YYSTYPE}. The allowable types are now
+double-floats (for @code{exp} and @code{NUM}) and pointers to entries in
+the symbol table. @xref{Union Decl, ,The Collection of Value Types}.
+
+Since values can now have various types, it is necessary to associate a
+type with each grammar symbol whose semantic value is used. These symbols
+are @code{NUM}, @code{VAR}, @code{FNCT}, and @code{exp}. Their
+declarations are augmented with information about their data type (placed
+between angle brackets).
+
+The Bison construct @code{%type} is used for declaring nonterminal
+symbols, just as @code{%token} is used for declaring token types. We
+have not used @code{%type} before because nonterminal symbols are
+normally declared implicitly by the rules that define them. But
+@code{exp} must be declared explicitly so we can specify its value type.

+@node Mfcalc Symbol Table
+@subsection The @code{mfcalc} Symbol Table
+@cindex symbol table example
+
+The multi-function calculator requires a symbol table to keep track of the
+names and meanings of variables and functions. This doesn't affect the
+grammar rules (except for the actions) or the Bison declarations, but it
+requires some additional C functions for support.
+
+The symbol table itself consists of a linked list of records. Its
+definition, which is kept in the header @file{calc.h}, is as follows. It
+provides for either functions or variables to be placed in the table.
+
+@comment file: calc.h
+@example
+@group
+/* Function type. */
+typedef double (*func_t) (double);
+@end group
+
+@group
+/* Data type for links in the chain of symbols. */
+struct symrec
+@{
+ char *name; /* name of symbol */
+ int type; /* type of symbol: either VAR or FNCT */
+ union
+ @{
+ double var; /* value of a VAR */
+ func_t fnctptr; /* value of a FNCT */
+ @} value;
+ struct symrec *next; /* link field */
+@};
+@end group
+
+@group
+typedef struct symrec symrec;
+
+/* The symbol table: a chain of `struct symrec'. */
+extern symrec *sym_table;
+
+symrec *putsym (char const *, int);
+symrec *getsym (char const *);
+@end group
+@end example
+
+The new version of @code{main} includes a call to @code{init_table}, a
+function that initializes the symbol table. Here it is, and
+@code{init_table} as well:
+
+@comment file: mfcalc.y: 3
+@example
+#include <stdio.h>
+
+@group
+/* Called by yyparse on error. */
+void
+yyerror (char const *s)
+@{
+ printf ("%s\n", s);
+@}
+@end group
+
+@group
+struct init
+@{
+ char const *fname;
+ double (*fnct) (double);
+@};
+@end group
+
+@group
+struct init const arith_fncts[] =
+@{
+ "sin", sin,
+ "cos", cos,
+ "atan", atan,
+ "ln", log,
+ "exp", exp,
+ "sqrt", sqrt,
+ 0, 0
+@};
+@end group
+
+@group
+/* The symbol table: a chain of `struct symrec'. */
+symrec *sym_table;
+@end group
+

+init_table (void)
+@{
+ int i;
+ for (i = 0; arith_fncts[i].fname != 0; i++)
+ @{
+ symrec *ptr = putsym (arith_fncts[i].fname, FNCT);
+ ptr->value.fnctptr = arith_fncts[i].fnct;
+ @}
+@}
+@end group
+
+@group
+int
+main (void)
+@{
+ init_table ();
+ return yyparse ();
+@}
+@end group
+@end example
+
+By simply editing the initialization list and adding the necessary include
+files, you can add additional functions to the calculator.
+
+Two important functions allow look-up and installation of symbols in the
+symbol table. The function @code{putsym} is passed a name and the type
+(@code{VAR} or @code{FNCT}) of the object to be installed. The object is
+linked to the front of the list, and a pointer to the object is returned.
+The function @code{getsym} is passed the name of the symbol to look up. If
+found, a pointer to that symbol is returned; otherwise zero is returned.
+
+@comment file: mfcalc.y: 3
+@example
+#include <stdlib.h> /* malloc. */
+#include <string.h> /* strlen. */
+
+@group
+symrec *
+putsym (char const *sym_name, int sym_type)
+@{
+ symrec *ptr = (symrec *) malloc (sizeof (symrec));
+ ptr->name = (char *) malloc (strlen (sym_name) + 1);
+ strcpy (ptr->name,sym_name);
+ ptr->type = sym_type;
+ ptr->value.var = 0; /* Set value to 0 even if fctn. */
+ ptr->next = (struct symrec *)sym_table;
+ sym_table = ptr;
+ return ptr;
+@}
+@end group
+
+@group
+symrec *
+getsym (char const *sym_name)
+@{
+ symrec *ptr;
+ for (ptr = sym_table; ptr != (symrec *) 0;
+ ptr = (symrec *)ptr->next)
+ if (strcmp (ptr->name,sym_name) == 0)
+ return ptr;
+ return 0;
+@}
+@end group
+@end example
+
+The function @code{yylex} must now recognize variables, numeric values, and
+the single-character arithmetic operators. Strings of alphanumeric
+characters with a leading letter are recognized as either variables or
+functions depending on what the symbol table says about them.
+
+The string is passed to @code{getsym} for look up in the symbol table. If
+the name appears in the table, a pointer to its location and its type
+(@code{VAR} or @code{FNCT}) is returned to @code{yyparse}. If it is not
+already in the table, then it is installed as a @code{VAR} using
+@code{putsym}. Again, a pointer and its type (which must be @code{VAR}) is
+returned to @code{yyparse}.
+
+No change is needed in the handling of numeric values and arithmetic
+operators in @code{yylex}.
+
+@comment file: mfcalc.y: 3

+@end group
+@end example
+
+The error reporting function is unchanged, and the new version of
+@code{main} includes a call to @code{init_table} and sets the @code{yydebug}
+on user demand (@xref{Tracing, , Tracing Your Parser}, for details):
+

+
+@node Prologue
+@subsection The prologue
+@cindex declarations section
+@cindex Prologue
+@cindex declarations
+
+The @var{Prologue} section contains macro definitions and declarations
+of functions and variables that are used in the actions in the grammar
+rules. These are copied to the beginning of the parser implementation
+file so that they precede the definition of @code{yyparse}. You can
+use @samp{#include} to get the declarations from a header file. If
+you don't need any C declarations, you may omit the @samp{%@{} and
+@samp{%@}} delimiters that bracket this section.
+
+The @var{Prologue} section is terminated by the first occurrence
+of @samp{%@}} that is outside a comment, a string literal, or a
+character constant.
+
+You may have more than one @var{Prologue} section, intermixed with the
+@var{Bison declarations}. This allows you to have C and Bison
+declarations that refer to each other. For example, the @code{%union}
+declaration may use types defined in a header file, and you may wish to
+prototype functions that take arguments of type @code{YYSTYPE}. This
+can be done with two @var{Prologue} blocks, one before and one after the
+@code{%union} declaration.
+
+@example
+%@{
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ #include "ptypes.h"
+%@}
+
+%union @{
+ long int n;
+ tree t; /* @r{@code{tree} is defined in @file{ptypes.h}.} */
+@}
+
+%@{
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+%@}
+
+@dots{}
+@end example
+
+When in doubt, it is usually safer to put prologue code before all
+Bison declarations, rather than after. For example, any definitions
+of feature test macros like @code{_GNU_SOURCE} or
+@code{_POSIX_C_SOURCE} should appear before all Bison declarations, as
+feature test macros can affect the behavior of Bison-generated
+@code{#include} directives.
+
+@node Prologue Alternatives
+@subsection Prologue Alternatives
+@cindex Prologue Alternatives
+
+@findex %code
+@findex %code requires
+@findex %code provides
+@findex %code top
+
+The functionality of @var{Prologue} sections can often be subtle and
+inflexible. As an alternative, Bison provides a @code{%code}
+directive with an explicit qualifier field, which identifies the
+purpose of the code and thus the location(s) where Bison should
+generate it. For C/C++, the qualifier can be omitted for the default
+location, or it can be one of @code{requires}, @code{provides},
+@code{top}. @xref{%code Summary}.
+
+Look again at the example of the previous section:
+
+@example
+%@{
+ #define _GNU_SOURCE
+ #include <stdio.h>
+ #include "ptypes.h"
+%@}
+
+%union @{
+ long int n;
+ tree t; /* @r{@code{tree} is defined in @file{ptypes.h}.} */
+@}
+
+%@{
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+%@}
+
+@dots{}
+@end example
+
+@noindent
+Notice that there are two @var{Prologue} sections here, but there's a
+subtle distinction between their functionality. For example, if you
+decide to override Bison's default definition for @code{YYLTYPE}, in
+which @var{Prologue} section should you write your new definition?
+You should write it in the first since Bison will insert that code
+into the parser implementation file @emph{before} the default
+@code{YYLTYPE} definition. In which @var{Prologue} section should you
+prototype an internal function, @code{trace_token}, that accepts
+@code{YYLTYPE} and @code{yytokentype} as arguments? You should
+prototype it in the second since Bison will insert that code
+@emph{after} the @code{YYLTYPE} and @code{yytokentype} definitions.
+
+This distinction in functionality between the two @var{Prologue} sections is
+established by the appearance of the @code{%union} between them.
+This behavior raises a few questions.
+First, why should the position of a @code{%union} affect definitions related to
+@code{YYLTYPE} and @code{yytokentype}?
+Second, what if there is no @code{%union}?
+In that case, the second kind of @var{Prologue} section is not available.
+This behavior is not intuitive.
+
+To avoid this subtle @code{%union} dependency, rewrite the example using a
+@code{%code top} and an unqualified @code{%code}.
+Let's go ahead and add the new @code{YYLTYPE} definition and the
+@code{trace_token} prototype at the same time:
+
+@example
+%code top @{
+ #define _GNU_SOURCE
+ #include <stdio.h>
+
+ /* WARNING: The following code really belongs
+ * in a `%code requires'; see below. */
+
+ #include "ptypes.h"
+ #define YYLTYPE YYLTYPE
+ typedef struct YYLTYPE
+ @{
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+ char *filename;
+ @} YYLTYPE;
+@}
+
+%union @{
+ long int n;
+ tree t; /* @r{@code{tree} is defined in @file{ptypes.h}.} */
+@}
+
+%code @{
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ static void trace_token (enum yytokentype token, YYLTYPE loc);
+@}
+
+@dots{}
+@end example
+
+@noindent
+In this way, @code{%code top} and the unqualified @code{%code} achieve the same
+functionality as the two kinds of @var{Prologue} sections, but it's always
+explicit which kind you intend.
+Moreover, both kinds are always available even in the absence of @code{%union}.
+
+The @code{%code top} block above logically contains two parts. The
+first two lines before the warning need to appear near the top of the
+parser implementation file. The first line after the warning is
+required by @code{YYSTYPE} and thus also needs to appear in the parser
+implementation file. However, if you've instructed Bison to generate
+a parser header file (@pxref{Decl Summary, ,%defines}), you probably
+want that line to appear before the @code{YYSTYPE} definition in that
+header file as well. The @code{YYLTYPE} definition should also appear
+in the parser header file to override the default @code{YYLTYPE}
+definition there.
+
+In other words, in the @code{%code top} block above, all but the first two
+lines are dependency code required by the @code{YYSTYPE} and @code{YYLTYPE}
+definitions.
+Thus, they belong in one or more @code{%code requires}:
+
+@example
+@group
+%code top @{
+ #define _GNU_SOURCE
+ #include <stdio.h>
+@}
+@end group
+
+@group
+%code requires @{
+ #include "ptypes.h"
+@}
+@end group
+@group
+%union @{
+ long int n;
+ tree t; /* @r{@code{tree} is defined in @file{ptypes.h}.} */
+@}
+@end group
+
+@group
+%code requires @{
+ #define YYLTYPE YYLTYPE
+ typedef struct YYLTYPE
+ @{
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+ char *filename;
+ @} YYLTYPE;
+@}
+@end group
+
+@group
+%code @{
+ static void print_token_value (FILE *, int, YYSTYPE);
+ #define YYPRINT(F, N, L) print_token_value (F, N, L)
+ static void trace_token (enum yytokentype token, YYLTYPE loc);
+@}
+@end group
+
+@dots{}
+@end example
+
+@noindent
+Now Bison will insert @code{#include "ptypes.h"} and the new
+@code{YYLTYPE} definition before the Bison-generated @code{YYSTYPE}
+and @code{YYLTYPE} definitions in both the parser implementation file
+and the parser header file. (By the same reasoning, @code{%code
+requires} would also be the appropriate place to write your own
+definition for @code{YYSTYPE}.)
+
+When you are writing dependency code for @code{YYSTYPE} and
+@code{YYLTYPE}, you should prefer @code{%code requires} over
+@code{%code top} regardless of whether you instruct Bison to generate
+a parser header file. When you are writing code that you need Bison
+to insert only into the parser implementation file and that has no
+special need to appear at the top of that file, you should prefer the
+unqualified @code{%code} over @code{%code top}. These practices will
+make the purpose of each block of your code explicit to Bison and to
+other developers reading your grammar file. Following these
+practices, we expect the unqualified @code{%code} and @code{%code
+requires} to be the most important of the four @var{Prologue}
+alternatives.
+
+At some point while developing your parser, you might decide to
+provide @code{trace_token} to modules that are external to your
+parser. Thus, you might wish for Bison to insert the prototype into
+both the parser header file and the parser implementation file. Since
+this function is not a dependency required by @code{YYSTYPE} or
+@code{YYLTYPE}, it doesn't make sense to move its prototype to a
+@code{%code requires}. More importantly, since it depends upon
+@code{YYLTYPE} and @code{yytokentype}, @code{%code requires} is not
+sufficient. Instead, move its prototype from the unqualified
+@code{%code} to a @code{%code provides}:
+
+@example
+@group
+%code top @{
+ #define _GNU_SOURCE

+Bison will insert the @code{trace_token} prototype into both the
+parser header file and the parser implementation file after the
+definitions for @code{yytokentype}, @code{YYLTYPE}, and
+@code{YYSTYPE}.
+
+The above examples are careful to write directives in an order that
+reflects the layout of the generated parser implementation and header
+files: @code{%code top}, @code{%code requires}, @code{%code provides},
+and then @code{%code}. While your grammar files may generally be
+easier to read if you also follow this order, Bison does not require
+it. Instead, Bison lets you choose an organization that makes sense
+to you.
+
+You may declare any of these directives multiple times in the grammar file.
+In that case, Bison concatenates the contained code in declaration order.
+This is the only way in which the position of one of these directives within
+the grammar file affects its functionality.
+
+The result of the previous two properties is greater flexibility in how you may
+organize your grammar file.
+For example, you may organize semantic-type-related directives by semantic
+type:
+
+@example
+@group
+%code requires @{ #include "type1.h" @}
+%union @{ type1 field1; @}
+%destructor @{ type1_free ($$); @} <field1>
+%printer @{ type1_print (yyoutput, $$); @} <field1>
+@end group
+
+@group
+%code requires @{ #include "type2.h" @}
+%union @{ type2 field2; @}
+%destructor @{ type2_free ($$); @} <field2>
+%printer @{ type2_print (yyoutput, $$); @} <field2>
+@end group
+@end example
+
+@noindent
+You could even place each of the above directive groups in the rules section of
+the grammar file next to the set of rules that uses the associated semantic
+type.
+(In the rules section, you must terminate each of those directives with a
+semicolon.)
+And you don't have to worry that some directive (like a @code{%union}) in the
+definitions section is going to adversely affect their functionality in some
+counter-intuitive manner just because it comes first.
+Such an organization is not possible using @var{Prologue} sections.
+
+This section has been concerned with explaining the advantages of the four
+@var{Prologue} alternatives over the original Yacc @var{Prologue}.
+However, in most cases when using these directives, you shouldn't need to
+think about all the low-level ordering issues discussed here.
+Instead, you should simply use these directives to label each block of your
+code according to its purpose and let Bison handle the ordering.
+@code{%code} is the most generic label.
+Move code to @code{%code requires}, @code{%code provides}, or @code{%code top}
+as needed.

+@node Bison Declarations
+@subsection The Bison Declarations Section
+@cindex Bison declarations (introduction)
+@cindex declarations, Bison (introduction)
+
+The @var{Bison declarations} section contains declarations that define
+terminal and nonterminal symbols, specify precedence, and so on.
+In some simple grammars you may not need any declarations.
+@xref{Declarations, ,Bison Declarations}.
+
+@node Grammar Rules
+@subsection The Grammar Rules Section
+@cindex grammar rules section
+@cindex rules section for grammar
+
+The @dfn{grammar rules} section contains one or more Bison grammar
+rules, and nothing else. @xref{Rules, ,Syntax of Grammar Rules}.
+
+There must always be at least one grammar rule, and the first
+@samp{%%} (which precedes the grammar rules) may never be omitted even
+if it is the first thing in the file.
+
+@node Epilogue
+@subsection The epilogue
+@cindex additional C code section
+@cindex epilogue
+@cindex C code, section for additional
+
+The @var{Epilogue} is copied verbatim to the end of the parser
+implementation file, just as the @var{Prologue} is copied to the
+beginning. This is the most convenient place to put anything that you
+want to have in the parser implementation file but which need not come
+before the definition of @code{yyparse}. For example, the definitions
+of @code{yylex} and @code{yyerror} often go here. Because C requires
+functions to be declared before being used, you often need to declare
+functions like @code{yylex} and @code{yyerror} in the Prologue, even
+if you define them in the Epilogue. @xref{Interface, ,Parser
+C-Language Interface}.
+
+If the last section is empty, you may omit the @samp{%%} that separates it
+from the grammar rules.
+
+The Bison parser itself contains many macros and identifiers whose names
+start with @samp{yy} or @samp{YY}, so it is a good idea to avoid using
+any such names (except those documented in this manual) in the epilogue
+of the grammar file.
+
+@node Symbols
+@section Symbols, Terminal and Nonterminal
+@cindex nonterminal symbol
+@cindex terminal symbol
+@cindex token type
+@cindex symbol
+
+@dfn{Symbols} in Bison grammars represent the grammatical classifications
+of the language.
+
+A @dfn{terminal symbol} (also known as a @dfn{token type}) represents a
+class of syntactically equivalent tokens. You use the symbol in grammar
+rules to mean that a token in that class is allowed. The symbol is
+represented in the Bison parser by a numeric code, and the @code{yylex}
+function returns a token type code to indicate what kind of token has
+been read. You don't need to know what the code value is; you can use
+the symbol to stand for it.
+
+A @dfn{nonterminal symbol} stands for a class of syntactically
+equivalent groupings. The symbol name is used in writing grammar rules.
+By convention, it should be all lower case.
+
+Symbol names can contain letters, underscores, periods, and non-initial
+digits and dashes. Dashes in symbol names are a GNU extension, incompatible
+with POSIX Yacc. Periods and dashes make symbol names less convenient to
+use with named references, which require brackets around such names
+(@pxref{Named References}). Terminal symbols that contain periods or dashes
+make little sense: since they are not valid symbols (in most programming
+languages) they are not exported as token names.
+
+There are three ways of writing terminal symbols in the grammar:
+
+@itemize @bullet
+@item
+A @dfn{named token type} is written with an identifier, like an
+identifier in C@. By convention, it should be all upper case. Each
+such name must be defined with a Bison declaration such as
+@code{%token}. @xref{Token Decl, ,Token Type Names}.
+
+@item
+@cindex character token
+@cindex literal token
+@cindex single-character literal
+A @dfn{character token type} (or @dfn{literal character token}) is
+written in the grammar using the same syntax used in C for character
+constants; for example, @code{'+'} is a character token type. A
+character token type doesn't need to be declared unless you need to
+specify its semantic value data type (@pxref{Value Type, ,Data Types of
+Semantic Values}), associativity, or precedence (@pxref{Precedence,
+,Operator Precedence}).
+
+By convention, a character token type is used only to represent a
+token that consists of that particular character. Thus, the token
+type @code{'+'} is used to represent the character @samp{+} as a
+token. Nothing enforces this convention, but if you depart from it,
+your program will confuse other readers.
+
+All the usual escape sequences used in character literals in C can be
+used in Bison as well, but you must not use the null character as a
+character literal because its numeric code, zero, signifies
+end-of-input (@pxref{Calling Convention, ,Calling Convention
+for @code{yylex}}). Also, unlike standard C, trigraphs have no
+special meaning in Bison character literals, nor is backslash-newline
+allowed.
+
+@item
+@cindex string token
+@cindex literal string token
+@cindex multicharacter literal
+A @dfn{literal string token} is written like a C string constant; for
+example, @code{"<="} is a literal string token. A literal string token
+doesn't need to be declared unless you need to specify its semantic
+value data type (@pxref{Value Type}), associativity, or precedence
+(@pxref{Precedence}).
+
+You can associate the literal string token with a symbolic name as an
+alias, using the @code{%token} declaration (@pxref{Token Decl, ,Token
+Declarations}). If you don't do that, the lexical analyzer has to
+retrieve the token number for the literal string token from the
+@code{yytname} table (@pxref{Calling Convention}).
+
+@strong{Warning}: literal string tokens do not work in Yacc.
+
+By convention, a literal string token is used only to represent a token
+that consists of that particular string. Thus, you should use the token
+type @code{"<="} to represent the string @samp{<=} as a token. Bison
+does not enforce this convention, but if you depart from it, people who
+read your program will be confused.
+
+All the escape sequences used in string literals in C can be used in
+Bison as well, except that you must not use a null character within a
+string literal. Also, unlike Standard C, trigraphs have no special
+meaning in Bison string literals, nor is backslash-newline allowed. A
+literal string token must contain two or more characters; for a token
+containing just one character, use a character token (see above).
+@end itemize
+
+How you choose to write a terminal symbol has no effect on its
+grammatical meaning. That depends only on where it appears in rules and
+on when the parser function returns that symbol.
+
+The value returned by @code{yylex} is always one of the terminal
+symbols, except that a zero or negative value signifies end-of-input.
+Whichever way you write the token type in the grammar rules, you write
+it the same way in the definition of @code{yylex}. The numeric code
+for a character token type is simply the positive numeric code of the
+character, so @code{yylex} can use the identical value to generate the
+requisite code, though you may need to convert it to @code{unsigned
+char} to avoid sign-extension on hosts where @code{char} is signed.
+Each named token type becomes a C macro in the parser implementation
+file, so @code{yylex} can use the name to stand for the code. (This
+is why periods don't make sense in terminal symbols.) @xref{Calling
+Convention, ,Calling Convention for @code{yylex}}.
+
+If @code{yylex} is defined in a separate file, you need to arrange for the
+token-type macro definitions to be available there. Use the @samp{-d}
+option when you run Bison, so that it will write these macro definitions
+into a separate header file @file{@var{name}.tab.h} which you can include
+in the other source files that need it. @xref{Invocation, ,Invoking Bison}.
+
+If you want to write a grammar that is portable to any Standard C
+host, you must use only nonnull character tokens taken from the basic
+execution character set of Standard C@. This set consists of the ten
+digits, the 52 lower- and upper-case English letters, and the
+characters in the following C-language string:
+
+@example
+"\a\b\t\n\v\f\r !\"#%&'()*+,-./:;<=>?[\\]^_@{|@}~"
+@end example
+
+The @code{yylex} function and Bison must use a consistent character set
+and encoding for character tokens. For example, if you run Bison in an
+ASCII environment, but then compile and run the resulting
+program in an environment that uses an incompatible character set like
+EBCDIC, the resulting program may not work because the tables
+generated by Bison will assume ASCII numeric values for
+character tokens. It is standard practice for software distributions to
+contain C source files that were generated by Bison in an
+ASCII environment, so installers on platforms that are
+incompatible with ASCII must rebuild those files before
+compiling them.
+
+The symbol @code{error} is a terminal symbol reserved for error recovery
+(@pxref{Error Recovery}); you shouldn't use it for any other purpose.
+In particular, @code{yylex} should never return this value. The default
+value of the error token is 256, unless you explicitly assigned 256 to
+one of your tokens with a @code{%token} declaration.
+
+@node Rules
+@section Syntax of Grammar Rules
+@cindex rule syntax
+@cindex grammar rule syntax
+@cindex syntax of grammar rules
+
+A Bison grammar rule has the following general form:
+
+@example
+@group
+@var{result}: @var{components}@dots{};
+@end group
+@end example
+
+@noindent
+where @var{result} is the nonterminal symbol that this rule describes,
+and @var{components} are various terminal and nonterminal symbols that
+are put together by this rule (@pxref{Symbols}).
+
+For example,
+
+@example
+@group
+exp: exp '+' exp;
+@end group
+@end example
+
+@noindent
+says that two groupings of type @code{exp}, with a @samp{+} token in between,
+can be combined into a larger grouping of type @code{exp}.
+
+White space in rules is significant only to separate symbols. You can add
+extra white space as you wish.
+
+Scattered among the components can be @var{actions} that determine
+the semantics of the rule. An action looks like this:
+
+@example
+@{@var{C statements}@}
+@end example
+
+@noindent
+@cindex braced code
+This is an example of @dfn{braced code}, that is, C code surrounded by
+braces, much like a compound statement in C@. Braced code can contain
+any sequence of C tokens, so long as its braces are balanced. Bison
+does not check the braced code for correctness directly; it merely
+copies the code to the parser implementation file, where the C
+compiler can check it.
+
+Within braced code, the balanced-brace count is not affected by braces
+within comments, string literals, or character constants, but it is
+affected by the C digraphs @samp{<%} and @samp{%>} that represent
+braces. At the top level braced code must be terminated by @samp{@}}
+and not by a digraph. Bison does not look for trigraphs, so if braced
+code uses trigraphs you should ensure that they do not affect the
+nesting of braces or the boundaries of comments, string literals, or
+character constants.
+
+Usually there is only one action and it follows the components.
+@xref{Actions}.
+
+@findex |
+Multiple rules for the same @var{result} can be written separately or can
+be joined with the vertical-bar character @samp{|} as follows:
+
+@example
+@group
+@var{result}:
+ @var{rule1-components}@dots{}
+| @var{rule2-components}@dots{}
+@dots{}
+;
+@end group
+@end example
+
+@noindent
+They are still considered distinct rules even when joined in this way.
+
+If @var{components} in a rule is empty, it means that @var{result} can
+match the empty string. For example, here is how to define a
+comma-separated sequence of zero or more @code{exp} groupings:
+
+@example
+@group
+expseq:
+ /* empty */
+| expseq1
+;
+@end group
+
+@group
+expseq1:
+ exp
+| expseq1 ',' exp
+;
+@end group
+@end example
+
+@noindent
+It is customary to write a comment @samp{/* empty */} in each rule
+with no components.
+
+@node Recursion
+@section Recursive Rules
+@cindex recursive rule
+
+A rule is called @dfn{recursive} when its @var{result} nonterminal
+appears also on its right hand side. Nearly all Bison grammars need to
+use recursion, because that is the only way to define a sequence of any
+number of a particular thing. Consider this recursive definition of a
+comma-separated sequence of one or more expressions:
+
+@example
+@group
+expseq1:
+ exp
+| expseq1 ',' exp
+;
+@end group
+@end example
+
+@cindex left recursion
+@cindex right recursion
+@noindent
+Since the recursive use of @code{expseq1} is the leftmost symbol in the
+right hand side, we call this @dfn{left recursion}. By contrast, here
+the same construct is defined using @dfn{right recursion}:
+
+@example
+@group
+expseq1:
+ exp
+| exp ',' expseq1
+;
+@end group
+@end example
+
+@noindent
+Any kind of sequence can be defined using either left recursion or right
+recursion, but you should always use left recursion, because it can
+parse a sequence of any number of elements with bounded stack space.
+Right recursion uses up space on the Bison stack in proportion to the
+number of elements in the sequence, because all the elements must be
+shifted onto the stack before the rule can be applied even once.
+@xref{Algorithm, ,The Bison Parser Algorithm}, for further explanation
+of this.
+
+@cindex mutual recursion
+@dfn{Indirect} or @dfn{mutual} recursion occurs when the result of the
+rule does not appear directly on its right hand side, but does appear
+in rules for other nonterminals which do appear on its right hand
+side.
+
+For example:
+
+@example
+@group
+expr:
+ primary
+| primary '+' primary
+;
+@end group
+
+@group
+primary:
+ constant
+| '(' expr ')'
+;
+@end group
+@end example
+
+@noindent
+defines two mutually-recursive nonterminals, since each refers to the
+other.
+
+@node Semantics
+@section Defining Language Semantics
+@cindex defining language semantics
+@cindex language semantics, defining
+
+The grammar rules for a language determine only the syntax. The semantics
+are determined by the semantic values associated with various tokens and
+groupings, and by the actions taken when various groupings are recognized.
+
+For example, the calculator calculates properly because the value
+associated with each expression is the proper number; it adds properly
+because the action for the grouping @w{@samp{@var{x} + @var{y}}} is to add
+the numbers associated with @var{x} and @var{y}.

+@node Value Type
+@subsection Data Types of Semantic Values
+@cindex semantic value type
+@cindex value type, semantic
+@cindex data types of semantic values
+@cindex default data type
+
+In a simple program it may be sufficient to use the same data type for
+the semantic values of all language constructs. This was true in the
+RPN and infix calculator examples (@pxref{RPN Calc, ,Reverse Polish
+Notation Calculator}).
+
+Bison normally uses the type @code{int} for semantic values if your
+program uses the same data type for all language constructs. To
+specify some other type, define @code{YYSTYPE} as a macro, like this:
+
+@example
+#define YYSTYPE double
+@end example
+
+@noindent
+@code{YYSTYPE}'s replacement list should be a type name
+that does not contain parentheses or square brackets.
+This macro definition must go in the prologue of the grammar file
+(@pxref{Grammar Outline, ,Outline of a Bison Grammar}).
+
+@node Multiple Types
+@subsection More Than One Value Type
+
+In most programs, you will need different data types for different kinds
+of tokens and groupings. For example, a numeric constant may need type
+@code{int} or @code{long int}, while a string constant needs type
+@code{char *}, and an identifier might need a pointer to an entry in the
+symbol table.
+
+To use more than one data type for semantic values in one parser, Bison
+requires you to do two things:
+
+@itemize @bullet
+@item
+Specify the entire collection of possible data types, either by using the
+@code{%union} Bison declaration (@pxref{Union Decl, ,The Collection of
+Value Types}), or by using a @code{typedef} or a @code{#define} to
+define @code{YYSTYPE} to be a union type whose member names are
+the type tags.
+
+@item
+Choose one of those types for each symbol (terminal or nonterminal) for
+which semantic values are used. This is done for tokens with the
+@code{%token} Bison declaration (@pxref{Token Decl, ,Token Type Names})
+and for groupings with the @code{%type} Bison declaration (@pxref{Type
+Decl, ,Nonterminal Symbols}).
+@end itemize
+
+@node Actions
+@subsection Actions
+@cindex action
+@vindex $$
+@vindex $@var{n}
+@vindex $@var{name}
+@vindex $[@var{name}]
+
+An action accompanies a syntactic rule and contains C code to be executed
+each time an instance of that rule is recognized. The task of most actions
+is to compute a semantic value for the grouping built by the rule from the
+semantic values associated with tokens or smaller groupings.
+
+An action consists of braced code containing C statements, and can be
+placed at any position in the rule;
+it is executed at that position. Most rules have just one action at the
+end of the rule, following all the components. Actions in the middle of
+a rule are tricky and used only for special purposes (@pxref{Mid-Rule
+Actions, ,Actions in Mid-Rule}).
+
+The C code in an action can refer to the semantic values of the
+components matched by the rule with the construct @code{$@var{n}},
+which stands for the value of the @var{n}th component. The semantic
+value for the grouping being constructed is @code{$$}. In addition,
+the semantic values of symbols can be accessed with the named
+references construct @code{$@var{name}} or @code{$[@var{name}]}.
+Bison translates both of these constructs into expressions of the
+appropriate type when it copies the actions into the parser
+implementation file. @code{$$} (or @code{$@var{name}}, when it stands
+for the current grouping) is translated to a modifiable lvalue, so it
+can be assigned to.
+
+Here is a typical example:
+
+@example
+@group
+exp:
+@dots{}
+| exp '+' exp @{ $$ = $1 + $3; @}
+@end group
+@end example
+
+Or, in terms of named references:
+
+@example
+@group
+exp[result]:
+@dots{}
+| exp[left] '+' exp[right] @{ $result = $left + $right; @}
+@end group
+@end example
+
+@noindent
+This rule constructs an @code{exp} from two smaller @code{exp} groupings
+connected by a plus-sign token. In the action, @code{$1} and @code{$3}
+(@code{$left} and @code{$right})
+refer to the semantic values of the two component @code{exp} groupings,
+which are the first and third symbols on the right hand side of the rule.
+The sum is stored into @code{$$} (@code{$result}) so that it becomes the
+semantic value of
+the addition-expression just recognized by the rule. If there were a
+useful semantic value associated with the @samp{+} token, it could be
+referred to as @code{$2}.
+
+@xref{Named References}, for more information about using the named
+references construct.
+
+Note that the vertical-bar character @samp{|} is really a rule
+separator, and actions are attached to a single rule. This is a
+difference with tools like Flex, for which @samp{|} stands for either
+``or'', or ``the same action as that of the next rule''. In the
+following example, the action is triggered only when @samp{b} is found:
+
+@example
+@group
+a-or-b: 'a'|'b' @{ a_or_b_found = 1; @};
+@end group
+@end example
+
+@cindex default action
+If you don't specify an action for a rule, Bison supplies a default:
+@w{@code{$$ = $1}.} Thus, the value of the first symbol in the rule
+becomes the value of the whole rule. Of course, the default action is
+valid only if the two data types match. There is no meaningful default
+action for an empty rule; every empty rule must have an explicit action
+unless the rule's value does not matter.
+
+@code{$@var{n}} with @var{n} zero or negative is allowed for reference
+to tokens and groupings on the stack @emph{before} those that match the
+current rule. This is a very risky practice, and to use it reliably
+you must be certain of the context in which the rule is applied. Here
+is a case in which you can use this reliably:
+
+@example
+@group
+foo:
+ expr bar '+' expr @{ @dots{} @}
+| expr bar '-' expr @{ @dots{} @}
+;
+@end group
+
+@group
+bar:
+ /* empty */ @{ previous_expr = $0; @}
+;
+@end group
+@end example
+
+As long as @code{bar} is used only in the fashion shown here, @code{$0}
+always refers to the @code{expr} which precedes @code{bar} in the
+definition of @code{foo}.
+
+@vindex yylval
+It is also possible to access the semantic value of the lookahead token, if
+any, from a semantic action.
+This semantic value is stored in @code{yylval}.
+@xref{Action Features, ,Special Features for Use in Actions}.
+
+@node Action Types
+@subsection Data Types of Values in Actions
+@cindex action data types
+@cindex data types in actions
+
+If you have chosen a single data type for semantic values, the @code{$$}
+and @code{$@var{n}} constructs always have that data type.
+
+If you have used @code{%union} to specify a variety of data types, then you
+must declare a choice among these types for each terminal or nonterminal
+symbol that can have a semantic value. Then each time you use @code{$$} or
+@code{$@var{n}}, its data type is determined by which symbol it refers to
+in the rule. In this example,
+
+@example
+@group
+exp:
+ @dots{}
+| exp '+' exp @{ $$ = $1 + $3; @}
+@end group
+@end example
+
+@noindent
+@code{$1} and @code{$3} refer to instances of @code{exp}, so they all
+have the data type declared for the nonterminal symbol @code{exp}. If
+@code{$2} were used, it would have the data type declared for the
+terminal symbol @code{'+'}, whatever that might be.
+
+Alternatively, you can specify the data type when you refer to the value,
+by inserting @samp{<@var{type}>} after the @samp{$} at the beginning of the
+reference. For example, if you have defined types as shown here:
+
+@example
+@group
+%union @{
+ int itype;
+ double dtype;
+@}
+@end group
+@end example
+
+@noindent
+then you can write @code{$<itype>1} to refer to the first subunit of the
+rule as an integer, or @code{$<dtype>1} to refer to it as a double.
+
+@node Mid-Rule Actions
+@subsection Actions in Mid-Rule
+@cindex actions in mid-rule
+@cindex mid-rule actions
+
+Occasionally it is useful to put an action in the middle of a rule.
+These actions are written just like usual end-of-rule actions, but they
+are executed before the parser even recognizes the following components.
+
+A mid-rule action may refer to the components preceding it using
+@code{$@var{n}}, but it may not refer to subsequent components because
+it is run before they are parsed.
+
+The mid-rule action itself counts as one of the components of the rule.
+This makes a difference when there is another action later in the same rule
+(and usually there is another at the end): you have to count the actions
+along with the symbols when working out which number @var{n} to use in
+@code{$@var{n}}.
+
+The mid-rule action can also have a semantic value. The action can set
+its value with an assignment to @code{$$}, and actions later in the rule
+can refer to the value using @code{$@var{n}}. Since there is no symbol
+to name the action, there is no way to declare a data type for the value
+in advance, so you must use the @samp{$<@dots{}>@var{n}} construct to
+specify a data type each time you refer to this value.
+
+There is no way to set the value of the entire rule with a mid-rule
+action, because assignments to @code{$$} do not have that effect. The
+only way to set the value for the entire rule is with an ordinary action
+at the end of the rule.
+
+Here is an example from a hypothetical compiler, handling a @code{let}
+statement that looks like @samp{let (@var{variable}) @var{statement}} and
+serves to create a variable named @var{variable} temporarily for the
+duration of @var{statement}. To parse this construct, we must put
+@var{variable} into the symbol table while @var{statement} is parsed, then
+remove it afterward. Here is how it is done:
+
+@example
+@group
+stmt:
+ LET '(' var ')'
+ @{ $<context>$ = push_context (); declare_variable ($3); @}
+ stmt
+ @{ $$ = $6; pop_context ($<context>5); @}
+@end group
+@end example
+
+@noindent
+As soon as @samp{let (@var{variable})} has been recognized, the first
+action is run. It saves a copy of the current semantic context (the
+list of accessible variables) as its semantic value, using alternative
+@code{context} in the data-type union. Then it calls
+@code{declare_variable} to add the new variable to that list. Once the
+first action is finished, the embedded statement @code{stmt} can be
+parsed. Note that the mid-rule action is component number 5, so the
+@samp{stmt} is component number 6.
+
+After the embedded statement is parsed, its semantic value becomes the
+value of the entire @code{let}-statement. Then the semantic value from the
+earlier action is used to restore the prior list of variables. This
+removes the temporary @code{let}-variable from the list so that it won't
+appear to exist while the rest of the program is parsed.
+
+@findex %destructor
+@cindex discarded symbols, mid-rule actions
+@cindex error recovery, mid-rule actions
+In the above example, if the parser initiates error recovery (@pxref{Error
+Recovery}) while parsing the tokens in the embedded statement @code{stmt},
+it might discard the previous semantic context @code{$<context>5} without
+restoring it.
+Thus, @code{$<context>5} needs a destructor (@pxref{Destructor Decl, , Freeing
+Discarded Symbols}).
+However, Bison currently provides no means to declare a destructor specific to
+a particular mid-rule action's semantic value.
+
+One solution is to bury the mid-rule action inside a nonterminal symbol and to
+declare a destructor for that symbol:
+
+@example
+@group
+%type <context> let
+%destructor @{ pop_context ($$); @} let
+
+%%
+
+stmt:
+ let stmt
+ @{
+ $$ = $2;
+ pop_context ($1);
+ @};
+
+let:
+ LET '(' var ')'
+ @{
+ $$ = push_context ();
+ declare_variable ($3);
+ @};
+
+@end group
+@end example
+
+@noindent
+Note that the action is now at the end of its rule.
+Any mid-rule action can be converted to an end-of-rule action in this way, and
+this is what Bison actually does to implement mid-rule actions.
+
+Taking action before a rule is completely recognized often leads to
+conflicts since the parser must commit to a parse in order to execute the
+action. For example, the following two rules, without mid-rule actions,
+can coexist in a working parser because the parser can shift the open-brace
+token and look at what follows before deciding whether there is a
+declaration or not:
+
+@example
+@group
+compound:
+ '@{' declarations statements '@}'
+| '@{' statements '@}'
+;
+@end group
+@end example
+
+@noindent
+But when we add a mid-rule action as follows, the rules become nonfunctional:
+
+@example
+@group
+compound:
+ @{ prepare_for_local_variables (); @}
+ '@{' declarations statements '@}'
+@end group
+@group
+| '@{' statements '@}'
+;
+@end group
+@end example
+
+@noindent
+Now the parser is forced to decide whether to run the mid-rule action
+when it has read no farther than the open-brace. In other words, it
+must commit to using one rule or the other, without sufficient
+information to do it correctly. (The open-brace token is what is called
+the @dfn{lookahead} token at this time, since the parser is still
+deciding what to do about it. @xref{Lookahead, ,Lookahead Tokens}.)
+
+You might think that you could correct the problem by putting identical
+actions into the two rules, like this:
+
+@example
+@group
+compound:
+ @{ prepare_for_local_variables (); @}
+ '@{' declarations statements '@}'
+| @{ prepare_for_local_variables (); @}
+ '@{' statements '@}'
+;
+@end group
+@end example
+
+@noindent
+But this does not help, because Bison does not realize that the two actions
+are identical. (Bison never tries to understand the C code in an action.)
+
+If the grammar is such that a declaration can be distinguished from a
+statement by the first token (which is true in C), then one solution which
+does work is to put the action after the open-brace, like this:
+
+@example
+@group
+compound:
+ '@{' @{ prepare_for_local_variables (); @}
+ declarations statements '@}'
+| '@{' statements '@}'
+;
+@end group
+@end example
+
+@noindent
+Now the first token of the following declaration or statement,
+which would in any case tell Bison which rule to use, can still do so.
+
+Another solution is to bury the action inside a nonterminal symbol which
+serves as a subroutine:
+
+@example
+@group
+subroutine:
+ /* empty */ @{ prepare_for_local_variables (); @}
+;
+@end group
+
+@group
+compound:
+ subroutine '@{' declarations statements '@}'
+| subroutine '@{' statements '@}'
+;
+@end group
+@end example
+
+@noindent
+Now Bison can execute the action in the rule for @code{subroutine} without
+deciding which rule for @code{compound} it will eventually use.

+@cindex textual location
+@cindex location, textual
+
+Though grammar rules and semantic actions are enough to write a fully
+functional parser, it can be useful to process some additional information,
+especially symbol locations.
+
+The way locations are handled is defined by providing a data type, and
+actions to take when rules are matched.
+
+@menu
+* Location Type:: Specifying a data type for locations.
+* Actions and Locations:: Using locations in actions.
+* Location Default Action:: Defining a general way to compute locations.
+@end menu
+
+@node Location Type
+@subsection Data Type of Locations
+@cindex data type of locations
+@cindex default location type
+
+Defining a data type for locations is much simpler than for semantic values,
+since all tokens and groupings always use the same type.
+
+You can specify the type of locations by defining a macro called
+@code{YYLTYPE}, just as you can specify the semantic value type by
+defining a @code{YYSTYPE} macro (@pxref{Value Type}).
+When @code{YYLTYPE} is not defined, Bison uses a default structure type with
+four members:
+
+@example
+typedef struct YYLTYPE
+@{
+ int first_line;
+ int first_column;
+ int last_line;
+ int last_column;
+@} YYLTYPE;
+@end example
+
+When @code{YYLTYPE} is not defined, at the beginning of the parsing, Bison
+initializes all these fields to 1 for @code{yylloc}. To initialize
+@code{yylloc} with a custom location type (or to chose a different
+initialization), use the @code{%initial-action} directive. @xref{Initial
+Action Decl, , Performing Actions before Parsing}.
+
+@node Actions and Locations
+@subsection Actions and Locations
+@cindex location actions
+@cindex actions, location
+@vindex @@$
+@vindex @@@var{n}
+@vindex @@@var{name}
+@vindex @@[@var{name}]
+
+Actions are not only useful for defining language semantics, but also for
+describing the behavior of the output parser with locations.
+
+The most obvious way for building locations of syntactic groupings is very
+similar to the way semantic values are computed. In a given rule, several
+constructs can be used to access the locations of the elements being matched.
+The location of the @var{n}th component of the right hand side is
+@code{@@@var{n}}, while the location of the left hand side grouping is
+@code{@@$}.
+
+In addition, the named references construct @code{@@@var{name}} and
+@code{@@[@var{name}]} may also be used to address the symbol locations.
+@xref{Named References}, for more information about using the named
+references construct.
+
+Here is a basic example using the default data type for locations:
+
+@example
+@group
+exp:
+ @dots{}
+| exp '/' exp
+ @{
+ @@$.first_column = @@1.first_column;
+ @@$.first_line = @@1.first_line;
+ @@$.last_column = @@3.last_column;
+ @@$.last_line = @@3.last_line;
+ if ($3)
+ $$ = $1 / $3;
+ else
+ @{
+ $$ = 1;
+ fprintf (stderr,
+ "Division by zero, l%d,c%d-l%d,c%d",
+ @@3.first_line, @@3.first_column,
+ @@3.last_line, @@3.last_column);
+ @}
+ @}
+@end group
+@end example
+
+As for semantic values, there is a default action for locations that is
+run each time a rule is matched. It sets the beginning of @code{@@$} to the
+beginning of the first symbol, and the end of @code{@@$} to the end of the
+last symbol.
+
+With this default action, the location tracking can be fully automatic. The
+example above simply rewrites this way:
+
+@example
+@group
+exp:
+ @dots{}
+| exp '/' exp
+ @{
+ if ($3)
+ $$ = $1 / $3;
+ else
+ @{
+ $$ = 1;
+ fprintf (stderr,
+ "Division by zero, l%d,c%d-l%d,c%d",
+ @@3.first_line, @@3.first_column,
+ @@3.last_line, @@3.last_column);
+ @}
+ @}
+@end group
+@end example
+
+@vindex yylloc
+It is also possible to access the location of the lookahead token, if any,
+from a semantic action.
+This location is stored in @code{yylloc}.
+@xref{Action Features, ,Special Features for Use in Actions}.
+
+@node Location Default Action
+@subsection Default Action for Locations
+@vindex YYLLOC_DEFAULT
+@cindex GLR parsers and @code{YYLLOC_DEFAULT}
+
+Actually, actions are not the best place to compute locations. Since
+locations are much more general than semantic values, there is room in
+the output parser to redefine the default action to take for each
+rule. The @code{YYLLOC_DEFAULT} macro is invoked each time a rule is
+matched, before the associated action is run. It is also invoked
+while processing a syntax error, to compute the error's location.
+Before reporting an unresolvable syntactic ambiguity, a GLR
+parser invokes @code{YYLLOC_DEFAULT} recursively to compute the location
+of that ambiguity.
+
+Most of the time, this macro is general enough to suppress location
+dedicated code from semantic actions.
+
+The @code{YYLLOC_DEFAULT} macro takes three parameters. The first one is
+the location of the grouping (the result of the computation). When a
+rule is matched, the second parameter identifies locations of
+all right hand side elements of the rule being matched, and the third
+parameter is the size of the rule's right hand side.
+When a GLR parser reports an ambiguity, which of multiple candidate
+right hand sides it passes to @code{YYLLOC_DEFAULT} is undefined.
+When processing a syntax error, the second parameter identifies locations
+of the symbols that were discarded during error processing, and the third
+parameter is the number of discarded symbols.
+
+By default, @code{YYLLOC_DEFAULT} is defined this way:
+
+@example
+@group
+# define YYLLOC_DEFAULT(Cur, Rhs, N) \
+do \
+ if (N) \
+ @{ \
+ (Cur).first_line = YYRHSLOC(Rhs, 1).first_line; \
+ (Cur).first_column = YYRHSLOC(Rhs, 1).first_column; \
+ (Cur).last_line = YYRHSLOC(Rhs, N).last_line; \
+ (Cur).last_column = YYRHSLOC(Rhs, N).last_column; \
+ @} \
+ else \
+ @{ \
+ (Cur).first_line = (Cur).last_line = \
+ YYRHSLOC(Rhs, 0).last_line; \
+ (Cur).first_column = (Cur).last_column = \
+ YYRHSLOC(Rhs, 0).last_column; \
+ @} \
+while (0)
+@end group
+@end example
+
+@noindent
+where @code{YYRHSLOC (rhs, k)} is the location of the @var{k}th symbol
+in @var{rhs} when @var{k} is positive, and the location of the symbol
+just before the reduction when @var{k} and @var{n} are both zero.
+
+When defining @code{YYLLOC_DEFAULT}, you should consider that:
+
+@itemize @bullet
+@item
+All arguments are free of side-effects. However, only the first one (the
+result) should be modified by @code{YYLLOC_DEFAULT}.
+
+@item
+For consistency with semantic actions, valid indexes within the
+right hand side range from 1 to @var{n}. When @var{n} is zero, only 0 is a
+valid index, and it refers to the symbol just before the reduction.
+During error processing @var{n} is always positive.
+
+@item
+Your macro should parenthesize its arguments, if need be, since the
+actual arguments may not be surrounded by parentheses. Also, your
+macro should expand to something that can be used as a single
+statement when it is followed by a semicolon.
+@end itemize
+
+@node Named References
+@section Named References
+@cindex named references
+
+As described in the preceding sections, the traditional way to refer to any
+semantic value or location is a @dfn{positional reference}, which takes the
+form @code{$@var{n}}, @code{$$}, @code{@@@var{n}}, and @code{@@$}. However,
+such a reference is not very descriptive. Moreover, if you later decide to
+insert or remove symbols in the right-hand side of a grammar rule, the need
+to renumber such references can be tedious and error-prone.
+
+To avoid these issues, you can also refer to a semantic value or location
+using a @dfn{named reference}. First of all, original symbol names may be
+used as named references. For example:
+
+@example
+@group
+invocation: op '(' args ')'
+ @{ $invocation = new_invocation ($op, $args, @@invocation); @}
+@end group
+@end example
+
+@noindent
+Positional and named references can be mixed arbitrarily. For example:
+
+@example
+@group
+invocation: op '(' args ')'
+ @{ $$ = new_invocation ($op, $args, @@$); @}
+@end group
+@end example
+
+@noindent
+However, sometimes regular symbol names are not sufficient due to
+ambiguities:
+
+@example
+@group
+exp: exp '/' exp
+ @{ $exp = $exp / $exp; @} // $exp is ambiguous.
+
+exp: exp '/' exp
+ @{ $$ = $1 / $exp; @} // One usage is ambiguous.
+
+exp: exp '/' exp
+ @{ $$ = $1 / $3; @} // No error.
+@end group
+@end example
+
+@noindent
+When ambiguity occurs, explicitly declared names may be used for values and
+locations. Explicit names are declared as a bracketed name after a symbol
+appearance in rule definitions. For example:
+@example
+@group
+exp[result]: exp[left] '/' exp[right]
+ @{ $result = $left / $right; @}
+@end group
+@end example
+
+@noindent
+In order to access a semantic value generated by a mid-rule action, an
+explicit name may also be declared by putting a bracketed name after the
+closing brace of the mid-rule action code:
+@example
+@group
+exp[res]: exp[x] '+' @{$left = $x;@}[left] exp[right]
+ @{ $res = $left + $right; @}
+@end group
+@end example
+
+@noindent
+
+In references, in order to specify names containing dots and dashes, an explicit
+bracketed syntax @code{$[name]} and @code{@@[name]} must be used:
+@example
+@group
+if-stmt: "if" '(' expr ')' "then" then.stmt ';'
+ @{ $[if-stmt] = new_if_stmt ($expr, $[then.stmt]); @}
+@end group
+@end example
+
+It often happens that named references are followed by a dot, dash or other
+C punctuation marks and operators. By default, Bison will read
+@samp{$name.suffix} as a reference to symbol value @code{$name} followed by
+@samp{.suffix}, i.e., an access to the @code{suffix} field of the semantic
+value. In order to force Bison to recognize @samp{name.suffix} in its
+entirety as the name of a semantic value, the bracketed syntax
+@samp{$[name.suffix]} must be used.
+
+The named references feature is experimental. More user feedback will help
+to stabilize it.

+
+@node Token Decl
+@subsection Token Type Names
+@cindex declaring token type names
+@cindex token type names, declaring
+@cindex declaring literal string tokens
+@findex %token
+
+The basic way to declare a token type name (terminal symbol) is as follows:
+
+@example
+%token @var{name}
+@end example
+
+Bison will convert this into a @code{#define} directive in
+the parser, so that the function @code{yylex} (if it is in this file)
+can use the name @var{name} to stand for this token type's code.
+
+Alternatively, you can use @code{%left}, @code{%right}, or
+@code{%nonassoc} instead of @code{%token}, if you wish to specify
+associativity and precedence. @xref{Precedence Decl, ,Operator
+Precedence}.
+
+You can explicitly specify the numeric code for a token type by appending
+a nonnegative decimal or hexadecimal integer value in the field immediately
+following the token name:
+
+@example
+%token NUM 300
+%token XNUM 0x12d // a GNU extension
+@end example
+
+@noindent
+It is generally best, however, to let Bison choose the numeric codes for
+all token types. Bison will automatically select codes that don't conflict
+with each other or with normal characters.
+
+In the event that the stack type is a union, you must augment the
+@code{%token} or other token declaration to include the data type
+alternative delimited by angle-brackets (@pxref{Multiple Types, ,More
+Than One Value Type}).
+
+For example:
+
+@example
+@group
+%union @{ /* define stack type */
+ double val;
+ symrec *tptr;
+@}
+%token <val> NUM /* define token NUM and its type */
+@end group
+@end example
+
+You can associate a literal string token with a token type name by
+writing the literal string at the end of a @code{%token}
+declaration which declares the name. For example:
+
+@example
+%token arrow "=>"
+@end example
+
+@noindent
+For example, a grammar for the C language might specify these names with
+equivalent literal string tokens:
+
+@example
+%token <operator> OR "||"
+%token <operator> LE 134 "<="
+%left OR "<="
+@end example
+
+@noindent
+Once you equate the literal string and the token name, you can use them
+interchangeably in further declarations or the grammar rules. The
+@code{yylex} function can use the token name or the literal string to
+obtain the token type code number (@pxref{Calling Convention}).
+Syntax error messages passed to @code{yyerror} from the parser will reference
+the literal string instead of the token name.
+
+The token numbered as 0 corresponds to end of file; the following line
+allows for nicer error messages referring to ``end of file'' instead
+of ``$end'':
+
+@example
+%token END 0 "end of file"
+@end example
+
+@node Precedence Decl
+@subsection Operator Precedence
+@cindex precedence declarations
+@cindex declaring operator precedence
+@cindex operator precedence, declaring
+
+Use the @code{%left}, @code{%right} or @code{%nonassoc} declaration to
+declare a token and specify its precedence and associativity, all at
+once. These are called @dfn{precedence declarations}.
+@xref{Precedence, ,Operator Precedence}, for general information on
+operator precedence.
+
+The syntax of a precedence declaration is nearly the same as that of
+@code{%token}: either
+
+@example
+%left @var{symbols}@dots{}
+@end example
+
+@noindent
+or
+
+@example
+%left <@var{type}> @var{symbols}@dots{}
+@end example
+
+And indeed any of these declarations serves the purposes of @code{%token}.
+But in addition, they specify the associativity and relative precedence for
+all the @var{symbols}:
+
+@itemize @bullet
+@item
+The associativity of an operator @var{op} determines how repeated uses
+of the operator nest: whether @samp{@var{x} @var{op} @var{y} @var{op}
+@var{z}} is parsed by grouping @var{x} with @var{y} first or by
+grouping @var{y} with @var{z} first. @code{%left} specifies
+left-associativity (grouping @var{x} with @var{y} first) and
+@code{%right} specifies right-associativity (grouping @var{y} with
+@var{z} first). @code{%nonassoc} specifies no associativity, which
+means that @samp{@var{x} @var{op} @var{y} @var{op} @var{z}} is
+considered a syntax error.
+
+@item
+The precedence of an operator determines how it nests with other operators.
+All the tokens declared in a single precedence declaration have equal
+precedence and nest together according to their associativity.
+When two tokens declared in different precedence declarations associate,
+the one declared later has the higher precedence and is grouped first.
+@end itemize
+
+For backward compatibility, there is a confusing difference between the
+argument lists of @code{%token} and precedence declarations.
+Only a @code{%token} can associate a literal string with a token type name.
+A precedence declaration always interprets a literal string as a reference to a
+separate token.
+For example:
+
+@example
+%left OR "<=" // Does not declare an alias.
+%left OR 134 "<=" 135 // Declares 134 for OR and 135 for "<=".
+@end example
+
+@node Union Decl
+@subsection The Collection of Value Types
+@cindex declaring value types
+@cindex value types, declaring
+@findex %union
+
+The @code{%union} declaration specifies the entire collection of
+possible data types for semantic values. The keyword @code{%union} is
+followed by braced code containing the same thing that goes inside a
+@code{union} in C@.
+
+For example:
+
+@example
+@group
+%union @{
+ double val;
+ symrec *tptr;
+@}
+@end group
+@end example
+
+@noindent
+This says that the two alternative types are @code{double} and @code{symrec
+*}. They are given names @code{val} and @code{tptr}; these names are used
+in the @code{%token} and @code{%type} declarations to pick one of the types
+for a terminal or nonterminal symbol (@pxref{Type Decl, ,Nonterminal Symbols}).
+
+As an extension to POSIX, a tag is allowed after the
+@code{union}. For example:
+
+@example
+@group
+%union value @{
+ double val;
+ symrec *tptr;
+@}
+@end group
+@end example
+
+@noindent
+specifies the union tag @code{value}, so the corresponding C type is
+@code{union value}. If you do not specify a tag, it defaults to
+@code{YYSTYPE}.
+
+As another extension to POSIX, you may specify multiple
+@code{%union} declarations; their contents are concatenated. However,
+only the first @code{%union} declaration can specify a tag.
+
+Note that, unlike making a @code{union} declaration in C, you need not write
+a semicolon after the closing brace.
+
+Instead of @code{%union}, you can define and use your own union type
+@code{YYSTYPE} if your grammar contains at least one
+@samp{<@var{type}>} tag. For example, you can put the following into
+a header file @file{parser.h}:
+
+@example
+@group
+union YYSTYPE @{
+ double val;
+ symrec *tptr;
+@};
+typedef union YYSTYPE YYSTYPE;
+@end group
+@end example
+
+@noindent
+and then your grammar can use the following
+instead of @code{%union}:
+
+@example
+@group
+%@{
+#include "parser.h"
+%@}
+%type <val> expr
+%token <tptr> ID
+@end group
+@end example
+
+@node Type Decl
+@subsection Nonterminal Symbols
+@cindex declaring value types, nonterminals
+@cindex value types, nonterminals, declaring
+@findex %type
+
+@noindent
+When you use @code{%union} to specify multiple value types, you must
+declare the value type of each nonterminal symbol for which values are
+used. This is done with a @code{%type} declaration, like this:
+
+@example
+%type <@var{type}> @var{nonterminal}@dots{}
+@end example
+
+@noindent
+Here @var{nonterminal} is the name of a nonterminal symbol, and
+@var{type} is the name given in the @code{%union} to the alternative
+that you want (@pxref{Union Decl, ,The Collection of Value Types}). You
+can give any number of nonterminal symbols in the same @code{%type}
+declaration, if they have the same value type. Use spaces to separate
+the symbol names.
+
+You can also declare the value type of a terminal symbol. To do this,
+use the same @code{<@var{type}>} construction in a declaration for the
+terminal symbol. All kinds of token declarations allow
+@code{<@var{type}>}.

+@subsection Performing Actions before Parsing
+@findex %initial-action
+
+Sometimes your parser needs to perform some initializations before
+parsing. The @code{%initial-action} directive allows for such arbitrary
+code.
+
+@deffn {Directive} %initial-action @{ @var{code} @}
+@findex %initial-action
+Declare that the braced @var{code} must be invoked before parsing each time
+@code{yyparse} is called. The @var{code} may use @code{$$} and
+@code{@@$} --- initial value and location of the lookahead --- and the
+@code{%parse-param}.
+@end deffn
+
+For instance, if your locations use a file name, you may use
+
+@example
+%parse-param @{ char const *file_name @};
+%initial-action
+@{
+ @@$.initialize (file_name);
+@};
+@end example

+@node Destructor Decl
+@subsection Freeing Discarded Symbols
+@cindex freeing discarded symbols
+@findex %destructor
+@findex <*>
+@findex <>
+During error recovery (@pxref{Error Recovery}), symbols already pushed
+on the stack and tokens coming from the rest of the file are discarded
+until the parser falls on its feet. If the parser runs out of memory,
+or if it returns via @code{YYABORT} or @code{YYACCEPT}, all the
+symbols on the stack must be discarded. Even if the parser succeeds, it
+must discard the start symbol.
+
+When discarded symbols convey heap based information, this memory is
+lost. While this behavior can be tolerable for batch parsers, such as
+in traditional compilers, it is unacceptable for programs like shells or
+protocol implementations that may parse and execute indefinitely.
+
+The @code{%destructor} directive defines code that is called when a
+symbol is automatically discarded.
+
+@deffn {Directive} %destructor @{ @var{code} @} @var{symbols}
+@findex %destructor
+Invoke the braced @var{code} whenever the parser discards one of the
+@var{symbols}.
+Within @var{code}, @code{$$} designates the semantic value associated
+with the discarded symbol, and @code{@@$} designates its location.
+The additional parser parameters are also available (@pxref{Parser Function, ,
+The Parser Function @code{yyparse}}).
+
+When a symbol is listed among @var{symbols}, its @code{%destructor} is called a
+per-symbol @code{%destructor}.
+You may also define a per-type @code{%destructor} by listing a semantic type
+tag among @var{symbols}.
+In that case, the parser will invoke this @var{code} whenever it discards any
+grammar symbol that has that semantic type tag unless that symbol has its own
+per-symbol @code{%destructor}.
+
+Finally, you can define two different kinds of default @code{%destructor}s.
+(These default forms are experimental.
+More user feedback will help to determine whether they should become permanent
+features.)
+You can place each of @code{<*>} and @code{<>} in the @var{symbols} list of
+exactly one @code{%destructor} declaration in your grammar file.
+The parser will invoke the @var{code} associated with one of these whenever it
+discards any user-defined grammar symbol that has no per-symbol and no per-type
+@code{%destructor}.
+The parser uses the @var{code} for @code{<*>} in the case of such a grammar
+symbol for which you have formally declared a semantic type tag (@code{%type}
+counts as such a declaration, but @code{$<tag>$} does not).
+The parser uses the @var{code} for @code{<>} in the case of such a grammar
+symbol that has no declared semantic type tag.
+@end deffn
+
+@noindent
+For example:
+
+@example
+%union @{ char *string; @}
+%token <string> STRING1
+%token <string> STRING2
+%type <string> string1
+%type <string> string2
+%union @{ char character; @}
+%token <character> CHR
+%type <character> chr
+%token TAGLESS
+
+%destructor @{ @} <character>
+%destructor @{ free ($$); @} <*>
+%destructor @{ free ($$); printf ("%d", @@$.first_line); @} STRING1 string1
+%destructor @{ printf ("Discarding tagless symbol.\n"); @} <>
+@end example
+
+@noindent
+guarantees that, when the parser discards any user-defined symbol that has a
+semantic type tag other than @code{<character>}, it passes its semantic value
+to @code{free} by default.
+However, when the parser discards a @code{STRING1} or a @code{string1}, it also
+prints its line number to @code{stdout}.
+It performs only the second @code{%destructor} in this case, so it invokes
+@code{free} only once.
+Finally, the parser merely prints a message whenever it discards any symbol,
+such as @code{TAGLESS}, that has no semantic type tag.
+
+A Bison-generated parser invokes the default @code{%destructor}s only for
+user-defined as opposed to Bison-defined symbols.
+For example, the parser will not invoke either kind of default
+@code{%destructor} for the special Bison-defined symbols @code{$accept},
+@code{$undefined}, or @code{$end} (@pxref{Table of Symbols, ,Bison Symbols}),
+none of which you can reference in your grammar.
+It also will not invoke either for the @code{error} token (@pxref{Table of
+Symbols, ,error}), which is always defined by Bison regardless of whether you
+reference it in your grammar.
+However, it may invoke one of them for the end token (token 0) if you
+redefine it from @code{$end} to, for example, @code{END}:
+
+@example
+%token END 0
+@end example
+
+@cindex actions in mid-rule
+@cindex mid-rule actions
+Finally, Bison will never invoke a @code{%destructor} for an unreferenced
+mid-rule semantic value (@pxref{Mid-Rule Actions,,Actions in Mid-Rule}).
+That is, Bison does not consider a mid-rule to have a semantic value if you
+do not reference @code{$$} in the mid-rule's action or @code{$@var{n}}
+(where @var{n} is the right-hand side symbol position of the mid-rule) in
+any later action in that rule. However, if you do reference either, the
+Bison-generated parser will invoke the @code{<>} @code{%destructor} whenever
+it discards the mid-rule symbol.
+
+@ignore
+@noindent
+In the future, it may be possible to redefine the @code{error} token as a
+nonterminal that captures the discarded symbols.
+In that case, the parser will invoke the default destructor for it as well.
+@end ignore
+
+@sp 1
+
+@cindex discarded symbols
+@dfn{Discarded symbols} are the following:
+
+@itemize
+@item
+stacked symbols popped during the first phase of error recovery,
+@item
+incoming terminals during the second phase of error recovery,
+@item
+the current lookahead and the entire stack (except the current
+right-hand side symbols) when the parser returns immediately, and
+@item
+the start symbol, when the parser succeeds.
+@end itemize
+
+The parser can @dfn{return immediately} because of an explicit call to
+@code{YYABORT} or @code{YYACCEPT}, or failed error recovery, or memory
+exhaustion.
+
+Right-hand side symbols of a rule that explicitly triggers a syntax
+error via @code{YYERROR} are not discarded automatically. As a rule
+of thumb, destructors are invoked only when user actions cannot manage
+the memory.
+
+@node Printer Decl
+@subsection Printing Semantic Values
+@cindex printing semantic values
+@findex %printer
+@findex <*>
+@findex <>
+When run-time traces are enabled (@pxref{Tracing, ,Tracing Your Parser}),
+the parser reports its actions, such as reductions. When a symbol involved
+in an action is reported, only its kind is displayed, as the parser cannot
+know how semantic values should be formatted.
+
+The @code{%printer} directive defines code that is called when a symbol is
+reported. Its syntax is the same as @code{%destructor} (@pxref{Destructor
+Decl, , Freeing Discarded Symbols}).
+
+@deffn {Directive} %printer @{ @var{code} @} @var{symbols}

+(a @code{FILE*} in C, and an @code{std::ostream&} in C++),
+@code{$$} designates the semantic value associated with the symbol, and
+@code{@@$} its location. The additional parser parameters are also
+available (@pxref{Parser Function, , The Parser Function @code{yyparse}}).
+
+The @var{symbols} are defined as for @code{%destructor} (@pxref{Destructor

+@samp{<ival>}), per-symbol (e.g., @samp{exp}, @samp{NUM}, @samp{"float"}),
+typed per-default (i.e., @samp{<*>}, or untyped per-default (i.e.,
+@samp{<>}).
+@end deffn

+@noindent
+guarantees that, when the parser print any symbol that has a semantic type
+tag other than @code{<character>}, it display the address of the semantic
+value by default. However, when the parser displays a @code{STRING1} or a
+@code{string1}, it formats it as a string in double quotes. It performs
+only the second @code{%printer} in this case, so it prints only once.
+Finally, the parser print @samp{<>} for any symbol, such as @code{TAGLESS},
+that has no semantic type tag. See also

+@node Expect Decl
+@subsection Suppressing Conflict Warnings
+@cindex suppressing conflict warnings
+@cindex preventing warnings about conflicts
+@cindex warnings, preventing
+@cindex conflicts, suppressing warnings of
+@findex %expect
+@findex %expect-rr
+
+Bison normally warns if there are any conflicts in the grammar
+(@pxref{Shift/Reduce, ,Shift/Reduce Conflicts}), but most real grammars
+have harmless shift/reduce conflicts which are resolved in a predictable
+way and would be difficult to eliminate. It is desirable to suppress
+the warning about these conflicts unless the number of conflicts
+changes. You can do this with the @code{%expect} declaration.
+
+The declaration looks like this:
+
+@example
+%expect @var{n}
+@end example
+
+Here @var{n} is a decimal integer. The declaration says there should
+be @var{n} shift/reduce conflicts and no reduce/reduce conflicts.
+Bison reports an error if the number of shift/reduce conflicts differs
+from @var{n}, or if there are any reduce/reduce conflicts.
+
+For deterministic parsers, reduce/reduce conflicts are more
+serious, and should be eliminated entirely. Bison will always report
+reduce/reduce conflicts for these parsers. With GLR
+parsers, however, both kinds of conflicts are routine; otherwise,
+there would be no need to use GLR parsing. Therefore, it is
+also possible to specify an expected number of reduce/reduce conflicts
+in GLR parsers, using the declaration:
+
+@example
+%expect-rr @var{n}
+@end example
+
+In general, using @code{%expect} involves these steps:
+
+@itemize @bullet
+@item
+Compile your grammar without @code{%expect}. Use the @samp{-v} option
+to get a verbose list of where the conflicts occur. Bison will also
+print the number of conflicts.
+
+@item
+Check each of the conflicts to make sure that Bison's default
+resolution is what you really want. If not, rewrite the grammar and
+go back to the beginning.
+
+@item
+Add an @code{%expect} declaration, copying the number @var{n} from the
+number which Bison printed. With GLR parsers, add an
+@code{%expect-rr} declaration as well.
+@end itemize
+
+Now Bison will report an error if you introduce an unexpected conflict,
+but will keep silent otherwise.
+
+@node Start Decl
+@subsection The Start-Symbol
+@cindex declaring the start symbol
+@cindex start symbol, declaring
+@cindex default start symbol
+@findex %start
+
+Bison assumes by default that the start symbol for the grammar is the first
+nonterminal specified in the grammar specification section. The programmer
+may override this restriction with the @code{%start} declaration as follows:
+
+@example
+%start @var{symbol}
+@end example
+
+@node Pure Decl
+@subsection A Pure (Reentrant) Parser
+@cindex reentrant parser
+@cindex pure parser
+@findex %define api.pure
+
+A @dfn{reentrant} program is one which does not alter in the course of
+execution; in other words, it consists entirely of @dfn{pure} (read-only)
+code. Reentrancy is important whenever asynchronous execution is possible;
+for example, a nonreentrant program may not be safe to call from a signal
+handler. In systems with multiple threads of control, a nonreentrant
+program must be called only within interlocks.
+
+Normally, Bison generates a parser which is not reentrant. This is
+suitable for most uses, and it permits compatibility with Yacc. (The
+standard Yacc interfaces are inherently nonreentrant, because they use
+statically allocated variables for communication with @code{yylex},
+including @code{yylval} and @code{yylloc}.)
+
+Alternatively, you can generate a pure, reentrant parser. The Bison
+declaration @code{%define api.pure} says that you want the parser to be
+reentrant. It looks like this:
+
+@example
+%define api.pure
+@end example
+
+The result is that the communication variables @code{yylval} and
+@code{yylloc} become local variables in @code{yyparse}, and a different
+calling convention is used for the lexical analyzer function
+@code{yylex}. @xref{Pure Calling, ,Calling Conventions for Pure
+Parsers}, for the details of this. The variable @code{yynerrs}
+becomes local in @code{yyparse} in pull mode but it becomes a member
+of yypstate in push mode. (@pxref{Error Reporting, ,The Error
+Reporting Function @code{yyerror}}). The convention for calling
+@code{yyparse} itself is unchanged.
+
+Whether the parser is pure has nothing to do with the grammar rules.
+You can generate either a pure parser or a nonreentrant parser from any
+valid grammar.
+
+@node Push Decl
+@subsection A Push Parser
+@cindex push parser
+@cindex push parser
+@findex %define api.push-pull
+
+(The current push parsing interface is experimental and may evolve.
+More user feedback will help to stabilize it.)
+
+A pull parser is called once and it takes control until all its input
+is completely parsed. A push parser, on the other hand, is called
+each time a new token is made available.
+
+A push parser is typically useful when the parser is part of a
+main event loop in the client's application. This is typically
+a requirement of a GUI, when the main event loop needs to be triggered
+within a certain time period.
+
+Normally, Bison generates a pull parser.
+The following Bison declaration says that you want the parser to be a push
+parser (@pxref{%define Summary,,api.push-pull}):
+
+@example
+%define api.push-pull push
+@end example
+
+In almost all cases, you want to ensure that your push parser is also
+a pure parser (@pxref{Pure Decl, ,A Pure (Reentrant) Parser}). The only
+time you should create an impure push parser is to have backwards
+compatibility with the impure Yacc pull mode interface. Unless you know
+what you are doing, your declarations should look like this:
+
+@example
+%define api.pure
+%define api.push-pull push
+@end example
+
+There is a major notable functional difference between the pure push parser
+and the impure push parser. It is acceptable for a pure push parser to have
+many parser instances, of the same type of parser, in memory at the same time.
+An impure push parser should only use one parser at a time.
+
+When a push parser is selected, Bison will generate some new symbols in
+the generated parser. @code{yypstate} is a structure that the generated
+parser uses to store the parser's state. @code{yypstate_new} is the
+function that will create a new parser instance. @code{yypstate_delete}
+will free the resources associated with the corresponding parser instance.
+Finally, @code{yypush_parse} is the function that should be called whenever a
+token is available to provide the parser. A trivial example
+of using a pure push parser would look like this:
+
+@example
+int status;
+yypstate *ps = yypstate_new ();
+do @{
+ status = yypush_parse (ps, yylex (), NULL);
+@} while (status == YYPUSH_MORE);
+yypstate_delete (ps);
+@end example
+
+If the user decided to use an impure push parser, a few things about
+the generated parser will change. The @code{yychar} variable becomes
+a global variable instead of a variable in the @code{yypush_parse} function.
+For this reason, the signature of the @code{yypush_parse} function is
+changed to remove the token as a parameter. A nonreentrant push parser
+example would thus look like this:
+
+@example
+extern int yychar;
+int status;
+yypstate *ps = yypstate_new ();
+do @{
+ yychar = yylex ();
+ status = yypush_parse (ps);
+@} while (status == YYPUSH_MORE);
+yypstate_delete (ps);
+@end example
+
+That's it. Notice the next token is put into the global variable @code{yychar}
+for use by the next invocation of the @code{yypush_parse} function.
+
+Bison also supports both the push parser interface along with the pull parser
+interface in the same generated parser. In order to get this functionality,
+you should replace the @code{%define api.push-pull push} declaration with the
+@code{%define api.push-pull both} declaration. Doing this will create all of
+the symbols mentioned earlier along with the two extra symbols, @code{yyparse}
+and @code{yypull_parse}. @code{yyparse} can be used exactly as it normally
+would be used. However, the user should note that it is implemented in the
+generated parser by calling @code{yypull_parse}.
+This makes the @code{yyparse} function that is generated with the
+@code{%define api.push-pull both} declaration slower than the normal
+@code{yyparse} function. If the user
+calls the @code{yypull_parse} function it will parse the rest of the input
+stream. It is possible to @code{yypush_parse} tokens to select a subgrammar
+and then @code{yypull_parse} the rest of the input stream. If you would like
+to switch back and forth between between parsing styles, you would have to
+write your own @code{yypull_parse} function that knows when to quit looking
+for input. An example of using the @code{yypull_parse} function would look
+like this:
+
+@example
+yypstate *ps = yypstate_new ();
+yypull_parse (ps); /* Will call the lexer */
+yypstate_delete (ps);
+@end example
+
+Adding the @code{%define api.pure} declaration does exactly the same thing to
+the generated parser with @code{%define api.push-pull both} as it did for
+@code{%define api.push-pull push}.

+definitions to be propagated to all modules, e.g., by putting them in
+a prerequisite header that is included both by your parser and by any

+
+Unless your parser is pure, the parser header file declares

+@var{i}. The first three elements of @code{yytname} correspond to the
+predefined tokens @code{"$end"}, @code{"error"}, and
+@code{"$undefined"}; after these come the symbols defined in the
+grammar file.
+
+The name in the table includes all the characters needed to represent
+the token in Bison. For single-character literals and literal
+strings, this includes the surrounding quoting characters and any
+escape sequences. For example, the Bison single-character literal
+@code{'+'} corresponds to a three-character name, represented in C as
+@code{"'+'"}; and the Bison two-character literal string @code{"\\/"}
+corresponds to a five-character name, represented in C as
+@code{"\"\\\\/\""}.
+
+When you specify @code{%token-table}, Bison also generates macro
+definitions for macros @code{YYNTOKENS}, @code{YYNNTS}, and

+@node %define Summary
+@subsection %define Summary
+
+There are many features of Bison's behavior that can be controlled by
+assigning the feature a single value. For historical reasons, some
+such features are assigned values by dedicated directives, such as
+@code{%start}, which assigns the start symbol. However, newer such
+features are associated with variables, which are assigned by the
+@code{%define} directive:
+
+@deffn {Directive} %define @var{variable}
+@deffnx {Directive} %define @var{variable} @var{value}
+@deffnx {Directive} %define @var{variable} "@var{value}"
+Define @var{variable} to @var{value}.
+
+@var{value} must be placed in quotation marks if it contains any
+character other than a letter, underscore, period, or non-initial dash
+or digit. Omitting @code{"@var{value}"} entirely is always equivalent
+to specifying @code{""}.
+
+It is an error if a @var{variable} is defined by @code{%define}
+multiple times, but see @ref{Bison Options,,-D
+@var{name}[=@var{value}]}.
+@end deffn
+
+The rest of this section summarizes variables and values that
+@code{%define} accepts.
+
+Some @var{variable}s take Boolean values. In this case, Bison will
+complain if the variable definition does not meet one of the following
+four conditions:
+
+@enumerate
+@item @code{@var{value}} is @code{true}
+
+@item @code{@var{value}} is omitted (or @code{""} is specified).
+This is equivalent to @code{true}.
+
+@item @code{@var{value}} is @code{false}.
+
+@item @var{variable} is never defined.
+In this case, Bison selects a default value.
+@end enumerate
+
+What @var{variable}s are accepted, as well as their meanings and default
+values, depend on the selected target language and/or the parser
+skeleton (@pxref{Decl Summary,,%language}, @pxref{Decl
+Summary,,%skeleton}).
+Unaccepted @var{variable}s produce an error.

+Bison uses @code{foo::bar} verbatim in references such as:

+foo::bar::parser::semantic_type
+@end smallexample
+
+However, to open a namespace, Bison removes any leading @code{::} and then

+This usage of @code{%name-prefix} is for backward compatibility and can be

+Thus, if you specify @code{%name-prefix}, it is best to also specify
+@code{%define namespace} so that @code{%name-prefix} @emph{only} affects the

+@cindex Prologue
+
+The @code{%code} directive inserts code verbatim into the output
+parser source at any of a predefined set of locations. It thus serves
+as a flexible and user-friendly alternative to the traditional Yacc
+prologue, @code{%@{@var{code}%@}}. This section summarizes the
+functionality of @code{%code} for the various target languages
+supported by Bison. For a detailed discussion of how to use
+@code{%code} in place of @code{%@{@var{code}%@}} for C/C++ and why it
+is advantageous to do so, @pxref{Prologue Alternatives}.
+
+@deffn {Directive} %code @{@var{code}@}
+This is the unqualified form of the @code{%code} directive. It
+inserts @var{code} verbatim at a language-dependent default location
+in the parser implementation.
+
+For C/C++, the default location is the parser implementation file
+after the usual contents of the parser header file. Thus, the
+unqualified form replaces @code{%@{@var{code}%@}} for most purposes.
+
+For Java, the default location is inside the parser class.
+@end deffn
+
+@deffn {Directive} %code @var{qualifier} @{@var{code}@}
+This is the qualified form of the @code{%code} directive.
+@var{qualifier} identifies the purpose of @var{code} and thus the
+location(s) where Bison should insert it. That is, if you need to
+specify location-sensitive @var{code} that does not belong at the
+default location selected by the unqualified @code{%code} form, use
+this form instead.
+@end deffn
+
+For any particular qualifier or for the unqualified form, if there are
+multiple occurrences of the @code{%code} directive, Bison concatenates
+the specified code in the order in which it appears in the grammar
+file.
+
+Not all qualifiers are accepted for all target languages. Unaccepted
+qualifiers produce an error. Some of the accepted qualifiers are:

+
+@node Multiple Parsers
+@section Multiple Parsers in the Same Program
+
+Most programs that use Bison parse only one language and therefore contain
+only one Bison parser. But what if you want to parse more than one language
+with the same program? Then you need to avoid name conflicts between
+different definitions of functions and variables such as @code{yyparse},
+@code{yylval}. To use different parsers from the same compilation unit, you
+also need to avoid conflicts on types and macros (e.g., @code{YYSTYPE})
+exported in the generated header.
+
+The easy way to do this is to define the @code{%define} variable
+@code{api.prefix}. With different @code{api.prefix}s it is guaranteed that
+headers do not conflict when included together, and that compiled objects
+can be linked together too. Specifying @samp{%define api.prefix
+@var{prefix}} (or passing the option @samp{-Dapi.prefix=@var{prefix}}, see
+@ref{Invocation, ,Invoking Bison}) renames the interface functions and
+variables of the Bison parser to start with @var{prefix} instead of
+@samp{yy}, and all the macros to start by @var{PREFIX} (i.e., @var{prefix}
+upper-cased) instead of @samp{YY}.
+
+The renamed symbols include @code{yyparse}, @code{yylex}, @code{yyerror},
+@code{yynerrs}, @code{yylval}, @code{yylloc}, @code{yychar} and
+@code{yydebug}. If you use a push parser, @code{yypush_parse},
+@code{yypull_parse}, @code{yypstate}, @code{yypstate_new} and
+@code{yypstate_delete} will also be renamed. The renamed macros include
+@code{YYSTYPE}, @code{YYLTYPE}, and @code{YYDEBUG}, which is treated
+specifically --- more about this below.
+
+For example, if you use @samp{%define api.prefix c}, the names become
+@code{cparse}, @code{clex}, @dots{}, @code{CSTYPE}, @code{CLTYPE}, and so
+on.
+
+The @code{%define} variable @code{api.prefix} works in two different ways.
+In the implementation file, it works by adding macro definitions to the
+beginning of the parser implementation file, defining @code{yyparse} as
+@code{@var{prefix}parse}, and so on:
+
+@example
+#define YYSTYPE CTYPE
+#define yyparse cparse
+#define yylval clval
+...
+YYSTYPE yylval;
+int yyparse (void);
+@end example
+
+This effectively substitutes one name for the other in the entire parser
+implementation file, thus the ``original'' names (@code{yylex},
+@code{YYSTYPE}, @dots{}) are also usable in the parser implementation file.
+
+However, in the parser header file, the symbols are defined renamed, for
+instance:
+
+@example
+extern CSTYPE clval;
+int cparse (void);
+@end example
+
+The macro @code{YYDEBUG} is commonly used to enable the tracing support in
+parsers. To comply with this tradition, when @code{api.prefix} is used,
+@code{YYDEBUG} (not renamed) is used as a default value:
+
+@example
+/* Enabling traces. */
+#ifndef CDEBUG
+# if defined YYDEBUG
+# if YYDEBUG
+# define CDEBUG 1
+# else
+# define CDEBUG 0
+# endif
+# else
+# define CDEBUG 0
+# endif
+#endif
+#if CDEBUG
+extern int cdebug;
+#endif
+@end example
+
+@sp 2
+
+Prior to Bison 2.6, a feature similar to @code{api.prefix} was provided by
+the obsolete directive @code{%name-prefix} (@pxref{Table of Symbols, ,Bison

+@node Parser Function
+@section The Parser Function @code{yyparse}
+@findex yyparse
+
+You call the function @code{yyparse} to cause parsing to occur. This
+function reads tokens, executes actions, and ultimately returns when it
+encounters end-of-input or an unrecoverable syntax error. You can also
+write an action which directs @code{yyparse} to return immediately
+without reading further.
+
+
+@deftypefun int yyparse (void)
+The value returned by @code{yyparse} is 0 if parsing was successful (return
+is due to end-of-input).
+
+The value is 1 if parsing failed because of invalid input, i.e., input
+that contains a syntax error or that causes @code{YYABORT} to be
+invoked.
+
+The value is 2 if parsing failed due to memory exhaustion.
+@end deftypefun
+
+In an action, you can cause immediate return from @code{yyparse} by using
+these macros:
+
+@defmac YYACCEPT
+@findex YYACCEPT
+Return immediately with value 0 (to report success).
+@end defmac
+
+@defmac YYABORT
+@findex YYABORT
+Return immediately with value 1 (to report failure).
+@end defmac
+
+If you use a reentrant parser, you can optionally pass additional
+parameter information to it in a reentrant way. To do so, use the
+declaration @code{%parse-param}:
+
+@deffn {Directive} %parse-param @{@var{argument-declaration}@}
+@findex %parse-param
+Declare that an argument declared by the braced-code
+@var{argument-declaration} is an additional @code{yyparse} argument.
+The @var{argument-declaration} is used when declaring
+functions or prototypes. The last identifier in
+@var{argument-declaration} must be the argument name.
+@end deffn
+
+Here's an example. Write this in the parser:
+
+@example
+%parse-param @{int *nastiness@}
+%parse-param @{int *randomness@}

+Then call the parser like this:
+
+@example
+@{
+ int nastiness, randomness;
+ @dots{} /* @r{Store proper data in @code{nastiness} and @code{randomness}.} */
+ value = yyparse (&nastiness, &randomness);
+ @dots{}
+@}

+call it. The function is sometimes referred to as a lexical scanner.
+
+In simple programs, @code{yylex} is often defined at the end of the
+Bison grammar file. If @code{yylex} is defined in a separate source
+file, you need to arrange for the token-type macro definitions to be
+available there. To do this, use the @samp{-d} option when you run
+Bison, so that it will write these macro definitions into the separate
+parser header file, @file{@var{name}.tab.h}, which you can include in
+the other source files that need it. @xref{Invocation, ,Invoking

+* Pure Calling:: How the calling convention differs in a pure parser
+ (@pxref{Pure Decl, ,A Pure (Reentrant) Parser}).
+@end menu
+
+@node Calling Convention
+@subsection Calling Convention for @code{yylex}
+
+The value that @code{yylex} returns must be the positive numeric code
+for the type of token it has just found; a zero or negative value
+signifies end-of-input.
+
+When a token is referred to in the grammar rules by a name, that name
+in the parser implementation file becomes a C macro whose definition
+is the proper numeric code for that token type. So @code{yylex} can
+use the name to indicate that type. @xref{Symbols}.
+
+When a token is referred to in the grammar rules by a character literal,
+the numeric code for that character is also the code for the token type.
+So @code{yylex} can simply return that character code, possibly converted
+to @code{unsigned char} to avoid sign-extension. The null character
+must not be used this way, because its code is zero and that
+signifies end-of-input.
+
+Here is an example showing these things:
+
+@example
+int
+yylex (void)
+@{
+ @dots{}
+ if (c == EOF) /* Detect end-of-input. */
+ return 0;
+ @dots{}
+ if (c == '+' || c == '-')
+ return c; /* Assume token type for `+' is '+'. */
+ @dots{}
+ return INT; /* Return the type of the token. */
+ @dots{}
+@}
+@end example
+
+@noindent
+This interface has been designed so that the output from the @code{lex}
+utility can be used without change as the definition of @code{yylex}.
+
+If the grammar uses literal string tokens, there are two ways that
+@code{yylex} can determine the token type codes for them:
+
+@itemize @bullet
+@item
+If the grammar defines symbolic token names as aliases for the
+literal string tokens, @code{yylex} can use these symbolic names like
+all others. In this case, the use of the literal string tokens in
+the grammar file has no effect on @code{yylex}.
+
+@item
+@code{yylex} can find the multicharacter token in the @code{yytname}
+table. The index of the token in the table is the token type's code.
+The name of a multicharacter token is recorded in @code{yytname} with a
+double-quote, the token's characters, and another double-quote. The
+token's characters are escaped as necessary to be suitable as input
+to Bison.
+
+Here's code for looking up a multicharacter token in @code{yytname},
+assuming that the characters of the token are stored in
+@code{token_buffer}, and assuming that the token does not contain any
+characters like @samp{"} that require escaping.
+
+@example
+for (i = 0; i < YYNTOKENS; i++)
+ @{
+ if (yytname[i] != 0
+ && yytname[i][0] == '"'
+ && ! strncmp (yytname[i] + 1, token_buffer,
+ strlen (token_buffer))
+ && yytname[i][strlen (token_buffer) + 1] == '"'
+ && yytname[i][strlen (token_buffer) + 2] == 0)
+ break;

+
+@node Token Values
+@subsection Semantic Values of Tokens
+
+@vindex yylval
+In an ordinary (nonreentrant) parser, the semantic value of the token must
+be stored into the global variable @code{yylval}. When you are using
+just one data type for semantic values, @code{yylval} has that type.
+Thus, if the type is @code{int} (the default), you might write this in
+@code{yylex}:
+
+@example
+@group
+ @dots{}
+ yylval = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ @dots{}
+@end group
+@end example
+
+When you are using multiple data types, @code{yylval}'s type is a union
+made from the @code{%union} declaration (@pxref{Union Decl, ,The
+Collection of Value Types}). So when you store a token's value, you
+must use the proper member of the union. If the @code{%union}
+declaration looks like this:
+
+@example
+@group
+%union @{
+ int intval;
+ double val;
+ symrec *tptr;
+@}
+@end group
+@end example
+
+@noindent
+then the code in @code{yylex} might look like this:
+
+@example
+@group
+ @dots{}
+ yylval.intval = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ @dots{}
+@end group
+@end example
+
+@node Token Locations
+@subsection Textual Locations of Tokens
+
+@vindex yylloc
+If you are using the @samp{@@@var{n}}-feature (@pxref{Tracking Locations})
+in actions to keep track of the textual locations of tokens and groupings,
+then you must provide this information in @code{yylex}. The function
+@code{yyparse} expects to find the textual location of a token just parsed
+in the global variable @code{yylloc}. So @code{yylex} must store the proper
+data in that variable.
+
+By default, the value of @code{yylloc} is a structure and you need only
+initialize the members that are going to be used by the actions. The
+four members are called @code{first_line}, @code{first_column},
+@code{last_line} and @code{last_column}. Note that the use of this
+feature makes the parser noticeably slower.
+
+@tindex YYLTYPE
+The data type of @code{yylloc} has the name @code{YYLTYPE}.
+
+@node Pure Calling
+@subsection Calling Conventions for Pure Parsers
+
+When you use the Bison declaration @code{%define api.pure} to request a
+pure, reentrant parser, the global communication variables @code{yylval}
+and @code{yylloc} cannot be used. (@xref{Pure Decl, ,A Pure (Reentrant)
+Parser}.) In such parsers the two global variables are replaced by
+pointers passed as arguments to @code{yylex}. You must declare them as
+shown here, and pass the information back by storing it through those
+pointers.
+
+@example
+int
+yylex (YYSTYPE *lvalp, YYLTYPE *llocp)
+@{
+ @dots{}
+ *lvalp = value; /* Put value onto Bison stack. */
+ return INT; /* Return the type of the token. */
+ @dots{}
+@}
+@end example
+
+If the grammar file does not use the @samp{@@} constructs to refer to
+textual locations, then the type @code{YYLTYPE} will not be defined. In
+this case, omit the second argument; @code{yylex} will be called with
+only one argument.
+
+
+If you wish to pass the additional parameter data to @code{yylex}, use
+@code{%lex-param} just like @code{%parse-param} (@pxref{Parser
+Function}).
+
+@deffn {Directive} lex-param @{@var{argument-declaration}@}
+@findex %lex-param
+Declare that the braced-code @var{argument-declaration} is an
+additional @code{yylex} argument declaration.
+@end deffn
+
+For instance:
+
+@example
+%parse-param @{int *nastiness@}
+%lex-param @{int *nastiness@}
+%parse-param @{int *randomness@}
+@end example
+
+@noindent
+results in the following signatures:
+
+@example
+int yylex (int *nastiness);
+int yyparse (int *nastiness, int *randomness);
+@end example
+
+If @code{%define api.pure} is added:
+
+@example
+int yylex (YYSTYPE *lvalp, int *nastiness);
+int yyparse (int *nastiness, int *randomness);
+@end example
+
+@noindent
+and finally, if both @code{%define api.pure} and @code{%locations} are used:
+
+@example
+int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness);
+int yyparse (int *nastiness, int *randomness);
+@end example
+
+@node Error Reporting
+@section The Error Reporting Function @code{yyerror}
+@cindex error reporting function
+@findex yyerror
+@cindex parse error
+@cindex syntax error
+
+The Bison parser detects a @dfn{syntax error} or @dfn{parse error}
+whenever it reads a token which cannot satisfy any syntax rule. An
+action in the grammar can also explicitly proclaim an error, using the
+macro @code{YYERROR} (@pxref{Action Features, ,Special Features for Use
+in Actions}).
+
+The Bison parser expects to report the error by calling an error
+reporting function named @code{yyerror}, which you must supply. It is
+called by @code{yyparse} whenever a syntax error is found, and it
+receives one argument. For a syntax error, the string is normally
+@w{@code{"syntax error"}}.
+
+@findex %error-verbose
+If you invoke the directive @code{%error-verbose} in the Bison declarations
+section (@pxref{Bison Declarations, ,The Bison Declarations Section}), then
+Bison provides a more verbose and specific error message string instead of
+just plain @w{@code{"syntax error"}}. However, that message sometimes
+contains incorrect information if LAC is not enabled (@pxref{LAC}).
+
+The parser can detect one other kind of error: memory exhaustion. This
+can happen when the input contains constructions that are very deeply
+nested. It isn't likely you will encounter this, since the Bison
+parser normally extends its stack automatically up to a very large limit. But
+if memory is exhausted, @code{yyparse} calls @code{yyerror} in the usual
+fashion, except that the argument string is @w{@code{"memory exhausted"}}.
+
+In some cases diagnostics like @w{@code{"syntax error"}} are
+translated automatically from English to some other language before
+they are passed to @code{yyerror}. @xref{Internationalization}.
+
+The following definition suffices in simple programs:
+
+@example
+@group
+void
+yyerror (char const *s)
+@{
+@end group
+@group
+ fprintf (stderr, "%s\n", s);
+@}
+@end group
+@end example
+
+After @code{yyerror} returns to @code{yyparse}, the latter will attempt
+error recovery if you have written suitable error recovery grammar rules
+(@pxref{Error Recovery}). If recovery is impossible, @code{yyparse} will
+immediately return 1.
+
+Obviously, in location tracking pure parsers, @code{yyerror} should have
+an access to the current location.
+This is indeed the case for the GLR
+parsers, but not for the Yacc parser, for historical reasons. I.e., if
+@samp{%locations %define api.pure} is passed then the prototypes for
+@code{yyerror} are:
+
+@example
+void yyerror (char const *msg); /* Yacc parsers. */
+void yyerror (YYLTYPE *locp, char const *msg); /* GLR parsers. */
+@end example
+
+If @samp{%parse-param @{int *nastiness@}} is used, then:
+
+@example
+void yyerror (int *nastiness, char const *msg); /* Yacc parsers. */
+void yyerror (int *nastiness, char const *msg); /* GLR parsers. */
+@end example
+
+Finally, GLR and Yacc parsers share the same @code{yyerror} calling
+convention for absolutely pure parsers, i.e., when the calling
+convention of @code{yylex} @emph{and} the calling convention of
+@code{%define api.pure} are pure.
+I.e.:
+
+@example
+/* Location tracking. */
+%locations
+/* Pure yylex. */
+%define api.pure
+%lex-param @{int *nastiness@}
+/* Pure yyparse. */
+%parse-param @{int *nastiness@}
+%parse-param @{int *randomness@}
+@end example
+
+@noindent
+results in the following signatures for all the parser kinds:
+
+@example
+int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness);
+int yyparse (int *nastiness, int *randomness);
+void yyerror (YYLTYPE *locp,
+ int *nastiness, int *randomness,
+ char const *msg);
+@end example
+
+@noindent
+The prototypes are only indications of how the code produced by Bison
+uses @code{yyerror}. Bison-generated code always ignores the returned
+value, so @code{yyerror} can return any type, including @code{void}.
+Also, @code{yyerror} can be a variadic function; that is why the
+message is always passed last.
+
+Traditionally @code{yyerror} returns an @code{int} that is always
+ignored, but this is purely for historical reasons, and @code{void} is
+preferable since it more accurately describes the return type for
+@code{yyerror}.
+
+@vindex yynerrs
+The variable @code{yynerrs} contains the number of syntax errors
+reported so far. Normally this variable is global; but if you
+request a pure parser (@pxref{Pure Decl, ,A Pure (Reentrant) Parser})
+then it is a local variable which only the actions can access.

+
+A Bison-generated parser can print diagnostics, including error and
+tracing messages. By default, they appear in English. However, Bison
+also supports outputting diagnostics in the user's native language. To
+make this work, the user should set the usual environment variables.
+@xref{Users, , The User's View, gettext, GNU @code{gettext} utilities}.
+For example, the shell command @samp{export LC_ALL=fr_CA.UTF-8} might
+set the user's locale to French Canadian using the UTF-8
+encoding. The exact set of available locales depends on the user's
+installation.
+
+The maintainer of a package that uses a Bison-generated parser enables
+the internationalization of the parser's output through the following
+steps. Here we assume a package that uses GNU Autoconf and
+GNU Automake.
+
+@enumerate
+@item
+@cindex bison-i18n.m4
+Into the directory containing the GNU Autoconf macros used
+by the package---often called @file{m4}---copy the
+@file{bison-i18n.m4} file installed by Bison under
+@samp{share/aclocal/bison-i18n.m4} in Bison's installation directory.
+For example:
+

+@end example
+
+@item

+@vindex BISON_LOCALEDIR
+@vindex YYENABLE_NLS
+In the top-level @file{configure.ac}, after the @code{AM_GNU_GETTEXT}
+invocation, add an invocation of @code{BISON_I18N}. This macro is
+defined in the file @file{bison-i18n.m4} that you copied earlier. It
+causes @samp{configure} to find the value of the
+@code{BISON_LOCALEDIR} variable, and it defines the source-language
+symbol @code{YYENABLE_NLS} to enable translations in the
+Bison-generated parser.
+
+@item
+In the @code{main} function of your program, designate the directory
+containing Bison's runtime message catalog, through a call to
+@samp{bindtextdomain} with domain name @samp{bison-runtime}.
+For example:
+
+@example
+bindtextdomain ("bison-runtime", BISON_LOCALEDIR);
+@end example
+
+Typically this appears after any other call @code{bindtextdomain
+(PACKAGE, LOCALEDIR)} that your package already has. Here we rely on
+@samp{BISON_LOCALEDIR} to be defined as a string through the
+@file{Makefile}.
+
+@item
+In the @file{Makefile.am} that controls the compilation of the @code{main}
+function, make @samp{BISON_LOCALEDIR} available as a C preprocessor macro,

+@chapter The Bison Parser Algorithm
+@cindex Bison parser algorithm
+@cindex algorithm of parser
+@cindex shifting
+@cindex reduction
+@cindex parser stack
+@cindex stack, parser
+
+As Bison reads tokens, it pushes them onto a stack along with their
+semantic values. The stack is called the @dfn{parser stack}. Pushing a
+token is traditionally called @dfn{shifting}.
+
+For example, suppose the infix calculator has read @samp{1 + 5 *}, with a
+@samp{3} to come. The stack will have four elements, one for each token
+that was shifted.
+
+But the stack does not always have an element for each token read. When
+the last @var{n} tokens and groupings shifted match the components of a
+grammar rule, they can be combined according to that rule. This is called
+@dfn{reduction}. Those tokens and groupings are replaced on the stack by a
+single grouping whose symbol is the result (left hand side) of that rule.
+Running the rule's action is part of the process of reduction, because this
+is what computes the semantic value of the resulting grouping.
+
+For example, if the infix calculator's parser stack contains this:
+
+@example
+1 + 5 * 3
+@end example
+
+@noindent
+and the next input token is a newline character, then the last three
+elements can be reduced to 15 via the rule:
+
+@example
+expr: expr '*' expr;
+@end example
+
+@noindent
+Then the stack contains just these three elements:
+
+@example
+1 + 15
+@end example
+
+@noindent
+At this point, another reduction can be made, resulting in the single value
+16. Then the newline token can be shifted.
+
+The parser tries, by shifts and reductions, to reduce the entire input down
+to a single grouping whose symbol is the grammar's start-symbol
+(@pxref{Language and Grammar, ,Languages and Context-Free Grammars}).
+
+This kind of parser is known in the literature as a bottom-up parser.

+@node Lookahead
+@section Lookahead Tokens
+@cindex lookahead token
+
+The Bison parser does @emph{not} always reduce immediately as soon as the
+last @var{n} tokens and groupings match a rule. This is because such a
+simple strategy is inadequate to handle most languages. Instead, when a
+reduction is possible, the parser sometimes ``looks ahead'' at the next
+token in order to decide what to do.
+
+When a token is read, it is not immediately shifted; first it becomes the
+@dfn{lookahead token}, which is not on the stack. Now the parser can
+perform one or more reductions of tokens and groupings on the stack, while
+the lookahead token remains off to the side. When no more reductions
+should take place, the lookahead token is shifted onto the stack. This
+does not mean that all possible reductions have been done; depending on the
+token type of the lookahead token, some rules may choose to delay their
+application.
+
+Here is a simple case where lookahead is needed. These three rules define
+expressions which contain binary addition operators and postfix unary
+factorial operators (@samp{!}), and allow parentheses for grouping.
+
+@example
+@group
+expr:
+ term '+' expr
+| term
+;
+@end group
+
+@group
+term:
+ '(' expr ')'
+| term '!'
+| NUMBER
+;
+@end group
+@end example
+
+Suppose that the tokens @w{@samp{1 + 2}} have been read and shifted; what
+should be done? If the following token is @samp{)}, then the first three
+tokens must be reduced to form an @code{expr}. This is the only valid
+course, because shifting the @samp{)} would produce a sequence of symbols
+@w{@code{term ')'}}, and no rule allows this.
+
+If the following token is @samp{!}, then it must be shifted immediately so
+that @w{@samp{2 !}} can be reduced to make a @code{term}. If instead the
+parser were to reduce before shifting, @w{@samp{1 + 2}} would become an
+@code{expr}. It would then be impossible to shift the @samp{!} because
+doing so would produce on the stack the sequence of symbols @code{expr
+'!'}. No rule allows that sequence.
+
+@vindex yychar
+@vindex yylval
+@vindex yylloc
+The lookahead token is stored in the variable @code{yychar}.
+Its semantic value and location, if any, are stored in the variables
+@code{yylval} and @code{yylloc}.
+@xref{Action Features, ,Special Features for Use in Actions}.
+
+@node Shift/Reduce
+@section Shift/Reduce Conflicts
+@cindex conflicts
+@cindex shift/reduce conflicts
+@cindex dangling @code{else}
+@cindex @code{else}, dangling
+
+Suppose we are parsing a language which has if-then and if-then-else
+statements, with a pair of rules like this:
+
+@example
+@group
+if_stmt:
+ IF expr THEN stmt
+| IF expr THEN stmt ELSE stmt
+;
+@end group
+@end example
+
+@noindent
+Here we assume that @code{IF}, @code{THEN} and @code{ELSE} are
+terminal symbols for specific keyword tokens.
+
+When the @code{ELSE} token is read and becomes the lookahead token, the
+contents of the stack (assuming the input is valid) are just right for
+reduction by the first rule. But it is also legitimate to shift the
+@code{ELSE}, because that would lead to eventual reduction by the second
+rule.
+
+This situation, where either a shift or a reduction would be valid, is
+called a @dfn{shift/reduce conflict}. Bison is designed to resolve
+these conflicts by choosing to shift, unless otherwise directed by
+operator precedence declarations. To see the reason for this, let's
+contrast it with the other alternative.
+
+Since the parser prefers to shift the @code{ELSE}, the result is to attach
+the else-clause to the innermost if-statement, making these two inputs
+equivalent:
+
+@example
+if x then if y then win (); else lose;
+
+if x then do; if y then win (); else lose; end;
+@end example
+
+But if the parser chose to reduce when possible rather than shift, the
+result would be to attach the else-clause to the outermost if-statement,
+making these two inputs equivalent:
+
+@example
+if x then if y then win (); else lose;
+
+if x then do; if y then win (); end; else lose;
+@end example
+
+The conflict exists because the grammar as written is ambiguous: either
+parsing of the simple nested if-statement is legitimate. The established
+convention is that these ambiguities are resolved by attaching the
+else-clause to the innermost if-statement; this is what Bison accomplishes
+by choosing to shift rather than reduce. (It would ideally be cleaner to

+This particular ambiguity was first encountered in the specifications of

+To avoid warnings from Bison about predictable, legitimate shift/reduce

+@node Why Precedence
+@subsection When Precedence is Needed
+
+Consider the following ambiguous grammar fragment (ambiguous because the
+input @w{@samp{1 - 2 * 3}} can be parsed in two different ways):
+
+@example
+@group
+expr:
+ expr '-' expr
+| expr '*' expr
+| expr '<' expr
+| '(' expr ')'
+@dots{}
+;
+@end group
+@end example
+
+@noindent
+Suppose the parser has seen the tokens @samp{1}, @samp{-} and @samp{2};
+should it reduce them via the rule for the subtraction operator? It
+depends on the next token. Of course, if the next token is @samp{)}, we
+must reduce; shifting is invalid because no single rule can reduce the
+token sequence @w{@samp{- 2 )}} or anything starting with that. But if
+the next token is @samp{*} or @samp{<}, we have a choice: either
+shifting or reduction would allow the parse to complete, but with
+different results.
+
+To decide which one Bison should do, we must consider the results. If
+the next operator token @var{op} is shifted, then it must be reduced
+first in order to permit another opportunity to reduce the difference.
+The result is (in effect) @w{@samp{1 - (2 @var{op} 3)}}. On the other
+hand, if the subtraction is reduced before shifting @var{op}, the result
+is @w{@samp{(1 - 2) @var{op} 3}}. Clearly, then, the choice of shift or
+reduce should depend on the relative precedence of the operators
+@samp{-} and @var{op}: @samp{*} should be shifted first, but not
+@samp{<}.
+
+@cindex associativity
+What about input such as @w{@samp{1 - 2 - 5}}; should this be
+@w{@samp{(1 - 2) - 5}} or should it be @w{@samp{1 - (2 - 5)}}? For most
+operators we prefer the former, which is called @dfn{left association}.
+The latter alternative, @dfn{right association}, is desirable for
+assignment operators. The choice of left or right association is a
+matter of whether the parser chooses to shift or reduce when the stack
+contains @w{@samp{1 - 2}} and the lookahead token is @samp{-}: shifting
+makes right-associativity.
+
+@node Using Precedence
+@subsection Specifying Operator Precedence
+@findex %left
+@findex %right
+@findex %nonassoc
+
+Bison allows you to specify these choices with the operator precedence
+declarations @code{%left} and @code{%right}. Each such declaration
+contains a list of tokens, which are operators whose precedence and
+associativity is being declared. The @code{%left} declaration makes all
+those operators left-associative and the @code{%right} declaration makes
+them right-associative. A third alternative is @code{%nonassoc}, which
+declares that it is a syntax error to find the same operator twice ``in a
+row''.
+
+The relative precedence of different operators is controlled by the
+order in which they are declared. The first @code{%left} or
+@code{%right} declaration in the file declares the operators whose
+precedence is lowest, the next such declaration declares the operators
+whose precedence is a little higher, and so on.
+
+@node Precedence Examples
+@subsection Precedence Examples
+
+In our example, we would want the following declarations:
+
+@example
+%left '<'
+%left '-'
+%left '*'
+@end example
+
+In a more complete example, which supports other operators as well, we
+would declare them in groups of equal precedence. For example, @code{'+'} is
+declared with @code{'-'}:
+
+@example
+%left '<' '>' '=' NE LE GE
+%left '+' '-'
+%left '*' '/'
+@end example
+
+@noindent
+(Here @code{NE} and so on stand for the operators for ``not equal''
+and so on. We assume that these tokens are more than one character long
+and therefore are represented by names, not character literals.)
+
+@node How Precedence
+@subsection How Precedence Works
+
+The first effect of the precedence declarations is to assign precedence
+levels to the terminal symbols declared. The second effect is to assign
+precedence levels to certain rules: each rule gets its precedence from
+the last terminal symbol mentioned in the components. (You can also
+specify explicitly the precedence of a rule. @xref{Contextual
+Precedence, ,Context-Dependent Precedence}.)
+
+Finally, the resolution of conflicts works by comparing the precedence
+of the rule being considered with that of the lookahead token. If the
+token's precedence is higher, the choice is to shift. If the rule's
+precedence is higher, the choice is to reduce. If they have equal
+precedence, the choice is made based on the associativity of that
+precedence level. The verbose output file made by @samp{-v}
+(@pxref{Invocation, ,Invoking Bison}) says how each conflict was
+resolved.
+
+Not all rules and not all tokens have precedence. If either the rule or
+the lookahead token has no precedence, then the default is to shift.
+
+@node Contextual Precedence
+@section Context-Dependent Precedence
+@cindex context-dependent precedence
+@cindex unary operator precedence
+@cindex precedence, context-dependent
+@cindex precedence, unary operator
+@findex %prec
+
+Often the precedence of an operator depends on the context. This sounds
+outlandish at first, but it is really very common. For example, a minus
+sign typically has a very high precedence as a unary operator, and a
+somewhat lower precedence (lower than multiplication) as a binary operator.
+
+The Bison precedence declarations, @code{%left}, @code{%right} and
+@code{%nonassoc}, can only be used once for a given token; so a token has
+only one precedence declared in this way. For context-dependent
+precedence, you need to use an additional mechanism: the @code{%prec}
+modifier for rules.
+
+The @code{%prec} modifier declares the precedence of a particular rule by
+specifying a terminal symbol whose precedence should be used for that rule.
+It's not necessary for that symbol to appear otherwise in the rule. The
+modifier's syntax is:
+
+@example
+%prec @var{terminal-symbol}
+@end example
+
+@noindent
+and it is written after the components of the rule. Its effect is to
+assign the rule the precedence of @var{terminal-symbol}, overriding
+the precedence that would be deduced for it in the ordinary way. The
+altered rule precedence then affects how conflicts involving that rule
+are resolved (@pxref{Precedence, ,Operator Precedence}).
+
+Here is how @code{%prec} solves the problem of unary minus. First, declare
+a precedence for a fictitious terminal symbol named @code{UMINUS}. There
+are no tokens of this type, but the symbol serves to stand for its
+precedence:
+
+@example
+@dots{}
+%left '+' '-'
+%left '*'
+%left UMINUS
+@end example
+
+Now the precedence of @code{UMINUS} can be used in specific rules:
+
+@example
+@group
+exp:
+ @dots{}
+| exp '-' exp
+ @dots{}
+| '-' exp %prec UMINUS
+@end group
+@end example
+
+@ifset defaultprec
+If you forget to append @code{%prec UMINUS} to the rule for unary
+minus, Bison silently assumes that minus has its usual precedence.
+This kind of problem can be tricky to debug, since one typically
+discovers the mistake only by testing the code.
+
+The @code{%no-default-prec;} declaration makes it easier to discover
+this kind of problem systematically. It causes rules that lack a
+@code{%prec} modifier to have no precedence, even if the last terminal
+symbol mentioned in their components has a declared precedence.
+
+If @code{%no-default-prec;} is in effect, you must specify @code{%prec}
+for all rules that participate in precedence conflict resolution.
+Then you will see any shift/reduce conflict until you tell Bison how
+to resolve it, either by changing your grammar or by adding an
+explicit precedence. This will probably add declarations to the
+grammar, but it helps to protect against incorrect rule precedences.
+
+The effect of @code{%no-default-prec;} can be reversed by giving
+@code{%default-prec;}, which is the default.

+@node Parser States
+@section Parser States
+@cindex finite-state machine
+@cindex parser state
+@cindex state (of parser)
+
+The function @code{yyparse} is implemented using a finite-state machine.
+The values pushed on the parser stack are not simply token type codes; they
+represent the entire sequence of terminal and nonterminal symbols at or
+near the top of the stack. The current state collects all the information
+about previous input which is relevant to deciding what to do next.
+
+Each time a lookahead token is read, the current parser state together
+with the type of lookahead token are looked up in a table. This table
+entry can say, ``Shift the lookahead token.'' In this case, it also
+specifies the new parser state, which is pushed onto the top of the
+parser stack. Or it can say, ``Reduce using rule number @var{n}.''
+This means that a certain number of tokens or groupings are taken off
+the top of the stack, and replaced by one grouping. In other words,
+that number of states are popped from the stack, and one new state is
+pushed.
+
+There is one other alternative: the table can say that the lookahead token
+is erroneous in the current state. This causes error processing to begin
+(@pxref{Error Recovery}).
+
+@node Reduce/Reduce
+@section Reduce/Reduce Conflicts
+@cindex reduce/reduce conflict
+@cindex conflicts, reduce/reduce
+
+A reduce/reduce conflict occurs if there are two or more rules that apply
+to the same sequence of input. This usually indicates a serious error
+in the grammar.
+
+For example, here is an erroneous attempt to define a sequence
+of zero or more @code{word} groupings.
+
+@example
+@group
+sequence:
+ /* empty */ @{ printf ("empty sequence\n"); @}
+| maybeword
+| sequence word @{ printf ("added word %s\n", $2); @}
+;
+@end group
+
+@group
+maybeword:
+ /* empty */ @{ printf ("empty maybeword\n"); @}
+| word @{ printf ("single word %s\n", $1); @}
+;
+@end group
+@end example
+
+@noindent
+The error is an ambiguity: there is more than one way to parse a single
+@code{word} into a @code{sequence}. It could be reduced to a
+@code{maybeword} and then into a @code{sequence} via the second rule.
+Alternatively, nothing-at-all could be reduced into a @code{sequence}
+via the first rule, and this could be combined with the @code{word}
+using the third rule for @code{sequence}.
+
+There is also more than one way to reduce nothing-at-all into a
+@code{sequence}. This can be done directly via the first rule,
+or indirectly via @code{maybeword} and then the second rule.
+
+You might think that this is a distinction without a difference, because it
+does not change whether any particular input is valid or not. But it does
+affect which actions are run. One parsing order runs the second rule's
+action; the other runs the first rule's action and the third rule's action.
+In this example, the output of the program changes.
+
+Bison resolves a reduce/reduce conflict by choosing to use the rule that
+appears first in the grammar, but it is very risky to rely on this. Every
+reduce/reduce conflict must be studied and usually eliminated. Here is the
+proper way to define @code{sequence}:
+
+@example
+sequence:
+ /* empty */ @{ printf ("empty sequence\n"); @}
+| sequence word @{ printf ("added word %s\n", $2); @}
+;
+@end example
+
+Here is another common error that yields a reduce/reduce conflict:
+
+@example
+sequence:
+ /* empty */
+| sequence words
+| sequence redirects
+;
+
+words:
+ /* empty */
+| words word
+;
+
+redirects:
+ /* empty */
+| redirects redirect
+;
+@end example
+
+@noindent
+The intention here is to define a sequence which can contain either
+@code{word} or @code{redirect} groupings. The individual definitions of
+@code{sequence}, @code{words} and @code{redirects} are error-free, but the
+three together make a subtle ambiguity: even an empty input can be parsed
+in infinitely many ways!
+
+Consider: nothing-at-all could be a @code{words}. Or it could be two
+@code{words} in a row, or three, or any number. It could equally well be a
+@code{redirects}, or two, or any number. Or it could be a @code{words}
+followed by three @code{redirects} and another @code{words}. And so on.
+
+Here are two ways to correct these rules. First, to make it a single level
+of sequence:
+
+@example
+sequence:
+ /* empty */
+| sequence word
+| sequence redirect
+;
+@end example
+
+Second, to prevent either a @code{words} or a @code{redirects}
+from being empty:
+
+@example
+@group
+sequence:
+ /* empty */
+| sequence words
+| sequence redirects
+;
+@end group
+
+@group
+words:
+ word
+| words word
+;
+@end group
+
+@group
+redirects:
+ redirect
+| redirects redirect
+;
+@end group

+@node Mysterious Conflicts
+@section Mysterious Conflicts
+@cindex Mysterious Conflicts
+
+Sometimes reduce/reduce conflicts can occur that don't look warranted.
+Here is an example:
+
+@example
+@group
+%token ID
+
+%%
+def: param_spec return_spec ',';
+param_spec:
+ type
+| name_list ':' type
+;

+type: ID;
+@end group
+@group
+name: ID;
+name_list:
+ name
+| name ',' name_list
+;
+@end group
+@end example
+
+It would seem that this grammar can be parsed with only a single token
+of lookahead: when a @code{param_spec} is being read, an @code{ID} is
+a @code{name} if a comma or colon follows, or a @code{type} if another
+@code{ID} follows. In other words, this grammar is LR(1).
+
+@cindex LR
+@cindex LALR
+However, for historical reasons, Bison cannot by default handle all
+LR(1) grammars.
+In this grammar, two contexts, that after an @code{ID} at the beginning
+of a @code{param_spec} and likewise at the beginning of a
+@code{return_spec}, are similar enough that Bison assumes they are the
+same.
+They appear similar because the same set of rules would be
+active---the rule for reducing to a @code{name} and that for reducing to
+a @code{type}. Bison is unable to determine at that stage of processing
+that the rules would require different lookahead tokens in the two
+contexts, so it makes a single parser state for them both. Combining
+the two contexts causes a conflict later. In parser terminology, this
+occurrence means that the grammar is not LALR(1).
+
+@cindex IELR
+@cindex canonical LR
+For many practical grammars (specifically those that fall into the non-LR(1)
+class), the limitations of LALR(1) result in difficulties beyond just
+mysterious reduce/reduce conflicts. The best way to fix all these problems
+is to select a different parser table construction algorithm. Either
+IELR(1) or canonical LR(1) would suffice, but the former is more efficient
+and easier to debug during development. @xref{LR Table Construction}, for
+details. (Bison's IELR(1) and canonical LR(1) implementations are
+experimental. More user feedback will help to stabilize them.)
+
+If you instead wish to work around LALR(1)'s limitations, you
+can often fix a mysterious conflict by identifying the two parser states
+that are being confused, and adding something to make them look
+distinct. In the above example, adding one rule to
+@code{return_spec} as follows makes the problem go away:
+
+@example
+@group
+%token BOGUS
+@dots{}
+%%
+@dots{}
+return_spec:
+ type
+| name ':' type
+| ID BOGUS /* This rule is never used. */
+;
+@end group
+@end example
+
+This corrects the problem because it introduces the possibility of an
+additional active rule in the context after the @code{ID} at the beginning of
+@code{return_spec}. This rule is not active in the corresponding context
+in a @code{param_spec}, so the two contexts receive distinct parser states.
+As long as the token @code{BOGUS} is never generated by @code{yylex},
+the added rule cannot alter the way actual input is parsed.
+
+In this particular example, there is another way to solve the problem:
+rewrite the rule for @code{return_spec} to use @code{ID} directly
+instead of via @code{name}. This also causes the two confusing
+contexts to have different sets of active rules, because the one for
+@code{return_spec} activates the altered rule for @code{return_spec}
+rather than the one for @code{name}.
+
+@example
+param_spec:
+ type
+| name_list ':' type
+;
+return_spec:
+ type
+| ID ':' type

+@subsection LR Table Construction
+@cindex Mysterious Conflict
+@cindex LALR
+@cindex IELR
+@cindex canonical LR
+@findex %define lr.type
+
+For historical reasons, Bison constructs LALR(1) parser tables by default.
+However, LALR does not possess the full language-recognition power of LR.
+As a result, the behavior of parsers employing LALR parser tables is often
+mysterious. We presented a simple example of this effect in @ref{Mysterious
+Conflicts}.
+
+As we also demonstrated in that example, the traditional approach to
+eliminating such mysterious behavior is to restructure the grammar.
+Unfortunately, doing so correctly is often difficult. Moreover, merely
+discovering that LALR causes mysterious behavior in your parser can be
+difficult as well.
+
+Fortunately, Bison provides an easy way to eliminate the possibility of such
+mysterious behavior altogether. You simply need to activate a more powerful
+parser table construction algorithm by using the @code{%define lr.type}
+directive.
+
+@deffn {Directive} {%define lr.type @var{TYPE}}
+Specify the type of parser tables within the LR(1) family. The accepted
+values for @var{TYPE} are:
+
+@itemize
+@item @code{lalr} (default)
+@item @code{ielr}
+@item @code{canonical-lr}
+@end itemize
+
+(This feature is experimental. More user feedback will help to stabilize
+it.)
+@end deffn
+
+For example, to activate IELR, you might add the following directive to you
+grammar file:
+
+@example
+%define lr.type ielr
+@end example
+
+@noindent For the example in @ref{Mysterious Conflicts}, the mysterious
+conflict is then eliminated, so there is no need to invest time in
+comprehending the conflict or restructuring the grammar to fix it. If,
+during future development, the grammar evolves such that all mysterious
+behavior would have disappeared using just LALR, you need not fear that
+continuing to use IELR will result in unnecessarily large parser tables.
+That is, IELR generates LALR tables when LALR (using a deterministic parsing
+algorithm) is sufficient to support the full language-recognition power of
+LR. Thus, by enabling IELR at the start of grammar development, you can
+safely and completely eliminate the need to consider LALR's shortcomings.
+
+While IELR is almost always preferable, there are circumstances where LALR
+or the canonical LR parser tables described by Knuth
+(@pxref{Bibliography,,Knuth 1965}) can be useful. Here we summarize the
+relative advantages of each parser table construction algorithm within
+Bison:
+
+@itemize
+@item LALR
+
+There are at least two scenarios where LALR can be worthwhile:
+
+@itemize
+@item GLR without static conflict resolution.
+
+@cindex GLR with LALR
+When employing GLR parsers (@pxref{GLR Parsers}), if you do not resolve any
+conflicts statically (for example, with @code{%left} or @code{%prec}), then
+the parser explores all potential parses of any given input. In this case,
+the choice of parser table construction algorithm is guaranteed not to alter
+the language accepted by the parser. LALR parser tables are the smallest
+parser tables Bison can currently construct, so they may then be preferable.
+Nevertheless, once you begin to resolve conflicts statically, GLR behaves
+more like a deterministic parser in the syntactic contexts where those
+conflicts appear, and so either IELR or canonical LR can then be helpful to
+avoid LALR's mysterious behavior.
+
+@item Malformed grammars.
+
+Occasionally during development, an especially malformed grammar with a
+major recurring flaw may severely impede the IELR or canonical LR parser
+table construction algorithm. LALR can be a quick way to construct parser
+tables in order to investigate such problems while ignoring the more subtle
+differences from IELR and canonical LR.
+@end itemize
+
+@item IELR
+
+IELR (Inadequacy Elimination LR) is a minimal LR algorithm. That is, given
+any grammar (LR or non-LR), parsers using IELR or canonical LR parser tables
+always accept exactly the same set of sentences. However, like LALR, IELR
+merges parser states during parser table construction so that the number of
+parser states is often an order of magnitude less than for canonical LR.
+More importantly, because canonical LR's extra parser states may contain
+duplicate conflicts in the case of non-LR grammars, the number of conflicts
+for IELR is often an order of magnitude less as well. This effect can
+significantly reduce the complexity of developing a grammar.
+
+@item Canonical LR
+
+@cindex delayed syntax error detection
+@cindex LAC
+@findex %nonassoc
+While inefficient, canonical LR parser tables can be an interesting means to
+explore a grammar because they possess a property that IELR and LALR tables
+do not. That is, if @code{%nonassoc} is not used and default reductions are
+left disabled (@pxref{Default Reductions}), then, for every left context of
+every canonical LR state, the set of tokens accepted by that state is
+guaranteed to be the exact set of tokens that is syntactically acceptable in
+that left context. It might then seem that an advantage of canonical LR
+parsers in production is that, under the above constraints, they are
+guaranteed to detect a syntax error as soon as possible without performing
+any unnecessary reductions. However, IELR parsers that use LAC are also
+able to achieve this behavior without sacrificing @code{%nonassoc} or
+default reductions. For details and a few caveats of LAC, @pxref{LAC}.

+@node Default Reductions
+@subsection Default Reductions
+@cindex default reductions
+@findex %define lr.default-reductions
+@findex %nonassoc
+
+After parser table construction, Bison identifies the reduction with the
+largest lookahead set in each parser state. To reduce the size of the
+parser state, traditional Bison behavior is to remove that lookahead set and
+to assign that reduction to be the default parser action. Such a reduction
+is known as a @dfn{default reduction}.
+
+Default reductions affect more than the size of the parser tables. They
+also affect the behavior of the parser:
+
+@itemize
+@item Delayed @code{yylex} invocations.
+
+@cindex delayed yylex invocations
+@cindex consistent states
+@cindex defaulted states
+A @dfn{consistent state} is a state that has only one possible parser
+action. If that action is a reduction and is encoded as a default
+reduction, then that consistent state is called a @dfn{defaulted state}.
+Upon reaching a defaulted state, a Bison-generated parser does not bother to
+invoke @code{yylex} to fetch the next token before performing the reduction.
+In other words, whether default reductions are enabled in consistent states
+determines how soon a Bison-generated parser invokes @code{yylex} for a
+token: immediately when it @emph{reaches} that token in the input or when it
+eventually @emph{needs} that token as a lookahead to determine the next
+parser action. Traditionally, default reductions are enabled, and so the
+parser exhibits the latter behavior.
+
+The presence of defaulted states is an important consideration when
+designing @code{yylex} and the grammar file. That is, if the behavior of
+@code{yylex} can influence or be influenced by the semantic actions
+associated with the reductions in defaulted states, then the delay of the
+next @code{yylex} invocation until after those reductions is significant.
+For example, the semantic actions might pop a scope stack that @code{yylex}
+uses to determine what token to return. Thus, the delay might be necessary
+to ensure that @code{yylex} does not look up the next token in a scope that
+should already be considered closed.
+
+@item Delayed syntax error detection.
+
+@cindex delayed syntax error detection
+When the parser fetches a new token by invoking @code{yylex}, it checks
+whether there is an action for that token in the current parser state. The
+parser detects a syntax error if and only if either (1) there is no action
+for that token or (2) the action for that token is the error action (due to
+the use of @code{%nonassoc}). However, if there is a default reduction in
+that state (which might or might not be a defaulted state), then it is
+impossible for condition 1 to exist. That is, all tokens have an action.
+Thus, the parser sometimes fails to detect the syntax error until it reaches
+a later state.

+@c If there's an infinite loop, default reductions can prevent an incorrect
+@c sentence from being rejected.
+While default reductions never cause the parser to accept syntactically
+incorrect sentences, the delay of syntax error detection can have unexpected
+effects on the behavior of the parser. However, the delay can be caused
+anyway by parser state merging and the use of @code{%nonassoc}, and it can
+be fixed by another Bison feature, LAC. We discuss the effects of delayed
+syntax error detection and LAC more in the next section (@pxref{LAC}).
+@end itemize
+
+For canonical LR, the only default reduction that Bison enables by default
+is the accept action, which appears only in the accepting state, which has
+no other action and is thus a defaulted state. However, the default accept
+action does not delay any @code{yylex} invocation or syntax error detection
+because the accept action ends the parse.
+
+For LALR and IELR, Bison enables default reductions in nearly all states by
+default. There are only two exceptions. First, states that have a shift
+action on the @code{error} token do not have default reductions because
+delayed syntax error detection could then prevent the @code{error} token
+from ever being shifted in that state. However, parser state merging can
+cause the same effect anyway, and LAC fixes it in both cases, so future
+versions of Bison might drop this exception when LAC is activated. Second,
+GLR parsers do not record the default reduction as the action on a lookahead
+token for which there is a conflict. The correct action in this case is to
+split the parse instead.
+
+To adjust which states have default reductions enabled, use the

+@cindex lookahead correction
+
+Canonical LR, IELR, and LALR can suffer from a couple of problems upon
+encountering a syntax error. First, the parser might perform additional
+parser stack reductions before discovering the syntax error. Such
+reductions can perform user semantic actions that are unexpected because
+they are based on an invalid token, and they cause error recovery to begin
+in a different syntactic context than the one in which the invalid token was
+encountered. Second, when verbose error messages are enabled (@pxref{Error
+Reporting}), the expected token list in the syntax error message can both
+contain invalid tokens and omit valid tokens.
+
+The culprits for the above problems are @code{%nonassoc}, default reductions
+in inconsistent states (@pxref{Default Reductions}), and parser state
+merging. Because IELR and LALR merge parser states, they suffer the most.
+Canonical LR can suffer only if @code{%nonassoc} is used or if default
+reductions are enabled for inconsistent states.
+
+LAC (Lookahead Correction) is a new mechanism within the parsing algorithm
+that solves these problems for canonical LR, IELR, and LALR without
+sacrificing @code{%nonassoc}, default reductions, or state merging. You can
+enable LAC with the @code{%define parse.lac} directive.
+
+@deffn {Directive} {%define parse.lac @var{VALUE}}
+Enable LAC to improve syntax error handling.
+@itemize
+@item @code{none} (default)
+@item @code{full}
+@end itemize
+(This feature is experimental. More user feedback will help to stabilize
+it. Moreover, it is currently only available for deterministic parsers in
+C.)
+@end deffn
+
+Conceptually, the LAC mechanism is straight-forward. Whenever the parser
+fetches a new token from the scanner so that it can determine the next
+parser action, it immediately suspends normal parsing and performs an
+exploratory parse using a temporary copy of the normal parser state stack.
+During this exploratory parse, the parser does not perform user semantic
+actions. If the exploratory parse reaches a shift action, normal parsing
+then resumes on the normal parser stacks. If the exploratory parse reaches
+an error instead, the parser reports a syntax error. If verbose syntax
+error messages are enabled, the parser must then discover the list of
+expected tokens, so it performs a separate exploratory parse for each token
+in the grammar.
+
+There is one subtlety about the use of LAC. That is, when in a consistent
+parser state with a default reduction, the parser will not attempt to fetch
+a token from the scanner because no lookahead is needed to determine the
+next parser action. Thus, whether default reductions are enabled in
+consistent states (@pxref{Default Reductions}) affects how soon the parser
+detects a syntax error: immediately when it @emph{reaches} an erroneous
+token or when it eventually @emph{needs} that token as a lookahead to
+determine the next parser action. The latter behavior is probably more
+intuitive, so Bison currently provides no way to achieve the former behavior
+while default reductions are enabled in consistent states.
+
+Thus, when LAC is in use, for some fixed decision of whether to enable
+default reductions in consistent states, canonical LR and IELR behave almost
+exactly the same for both syntactically acceptable and syntactically
+unacceptable input. While LALR still does not support the full
+language-recognition power of canonical LR and IELR, LAC at least enables
+LALR's syntax error handling to correctly reflect LALR's
+language-recognition power.
+
+There are a few caveats to consider when using LAC:
+
+@itemize
+@item Infinite parsing loops.
+
+IELR plus LAC does have one shortcoming relative to canonical LR. Some
+parsers generated by Bison can loop infinitely. LAC does not fix infinite
+parsing loops that occur between encountering a syntax error and detecting
+it, but enabling canonical LR or disabling default reductions sometimes
+does.
+
+@item Verbose error message limitations.
+
+Because of internationalization considerations, Bison-generated parsers
+limit the size of the expected token list they are willing to report in a
+verbose syntax error message. If the number of expected tokens exceeds that
+limit, the list is simply dropped from the message. Enabling LAC can
+increase the size of the list and thus cause the parser to drop it. Of
+course, dropping the list is better than reporting an incorrect list.
+
+@item Performance.
+
+Because LAC requires many parse actions to be performed twice, it can have a
+performance penalty. However, not all parse actions must be performed
+twice. Specifically, during a series of default reductions in consistent
+states and shift actions, the parser never has to initiate an exploratory
+parse. Moreover, the most time-consuming tasks in a parse are often the
+file I/O, the lexical analysis performed by the scanner, and the user's
+semantic actions, but none of these are performed during the exploratory
+parse. Finally, the base of the temporary stack used during an exploratory
+parse is a pointer into the normal parser state stack so that the stack is
+never physically copied. In our experience, the performance penalty of LAC
+has proved insignificant for practical grammars.
+@end itemize
+
+While the LAC algorithm shares techniques that have been recognized in the
+parser community for years, for the publication that introduces LAC,
+@pxref{Bibliography,,Denny 2010 May}.

+@node Unreachable States
+@subsection Unreachable States
+@findex %define lr.keep-unreachable-states
+@cindex unreachable states
+
+If there exists no sequence of transitions from the parser's start state to
+some state @var{s}, then Bison considers @var{s} to be an @dfn{unreachable
+state}. A state can become unreachable during conflict resolution if Bison
+disables a shift action leading to it from a predecessor state.
+
+By default, Bison removes unreachable states from the parser after conflict
+resolution because they are useless in the generated parser. However,
+keeping unreachable states is sometimes useful when trying to understand the
+relationship between the parser and the grammar.
+
+@deffn {Directive} {%define lr.keep-unreachable-states @var{VALUE}}
+Request that Bison allow unreachable states to remain in the parser tables.
+@var{VALUE} must be a Boolean. The default is @code{false}.
+@end deffn
+
+There are a few caveats to consider:
+
+@itemize @bullet
+@item Missing or extraneous warnings.
+
+Unreachable states may contain conflicts and may use rules not used in any
+other state. Thus, keeping unreachable states may induce warnings that are
+irrelevant to your parser's behavior, and it may eliminate warnings that are
+relevant. Of course, the change in warnings may actually be relevant to a
+parser table analysis that wants to keep unreachable states, so this
+behavior will likely remain in future Bison releases.
+
+@item Other useless states.
+
+While Bison is able to remove unreachable states, it is not guaranteed to
+remove other kinds of useless states. Specifically, when Bison disables
+reduce actions during conflict resolution, some goto actions may become
+useless, and thus some additional states may become useless. If Bison were
+to compute which goto actions were useless and then disable those actions,
+it could identify such states as unreachable and then remove those states.
+However, Bison does not compute which goto actions are useless.

+@node Generalized LR Parsing
+@section Generalized LR (GLR) Parsing
+@cindex GLR parsing
+@cindex generalized LR (GLR) parsing
+@cindex ambiguous grammars
+@cindex nondeterministic parsing
+
+Bison produces @emph{deterministic} parsers that choose uniquely
+when to reduce and which reduction to apply
+based on a summary of the preceding input and on one extra token of lookahead.
+As a result, normal Bison handles a proper subset of the family of
+context-free languages.
+Ambiguous grammars, since they have strings with more than one possible
+sequence of reductions cannot have deterministic parsers in this sense.
+The same is true of languages that require more than one symbol of
+lookahead, since the parser lacks the information necessary to make a
+decision at the point it must be made in a shift-reduce parser.
+Finally, as previously mentioned (@pxref{Mysterious Conflicts}),
+there are languages where Bison's default choice of how to
+summarize the input seen so far loses necessary information.
+
+When you use the @samp{%glr-parser} declaration in your grammar file,
+Bison generates a parser that uses a different algorithm, called
+Generalized LR (or GLR). A Bison GLR
+parser uses the same basic
+algorithm for parsing as an ordinary Bison parser, but behaves
+differently in cases where there is a shift-reduce conflict that has not
+been resolved by precedence rules (@pxref{Precedence}) or a
+reduce-reduce conflict. When a GLR parser encounters such a
+situation, it
+effectively @emph{splits} into a several parsers, one for each possible
+shift or reduction. These parsers then proceed as usual, consuming
+tokens in lock-step. Some of the stacks may encounter other conflicts
+and split further, with the result that instead of a sequence of states,
+a Bison GLR parsing stack is what is in effect a tree of states.
+
+In effect, each stack represents a guess as to what the proper parse
+is. Additional input may indicate that a guess was wrong, in which case
+the appropriate stack silently disappears. Otherwise, the semantics
+actions generated in each stack are saved, rather than being executed
+immediately. When a stack disappears, its saved semantic actions never
+get executed. When a reduction causes two stacks to become equivalent,
+their sets of semantic actions are both saved with the state that
+results from the reduction. We say that two stacks are equivalent
+when they both represent the same sequence of states,
+and each pair of corresponding states represents a
+grammar symbol that produces the same segment of the input token
+stream.
+
+Whenever the parser makes a transition from having multiple
+states to having one, it reverts to the normal deterministic parsing
+algorithm, after resolving and executing the saved-up actions.
+At this transition, some of the states on the stack will have semantic
+values that are sets (actually multisets) of possible actions. The
+parser tries to pick one of the actions by first finding one whose rule
+has the highest dynamic precedence, as set by the @samp{%dprec}
+declaration. Otherwise, if the alternative actions are not ordered by
+precedence, but there the same merging function is declared for both
+rules by the @samp{%merge} declaration,
+Bison resolves and evaluates both and then calls the merge function on
+the result. Otherwise, it reports an ambiguity.
+
+It is possible to use a data structure for the GLR parsing tree that
+permits the processing of any LR(1) grammar in linear time (in the
+size of the input), any unambiguous (not necessarily
+LR(1)) grammar in
+quadratic worst-case time, and any general (possibly ambiguous)
+context-free grammar in cubic worst-case time. However, Bison currently
+uses a simpler data structure that requires time proportional to the
+length of the input times the maximum number of stacks required for any
+prefix of the input. Thus, really ambiguous or nondeterministic
+grammars can require exponential time and space to process. Such badly
+behaving examples, however, are not generally of practical interest.
+Usually, nondeterminism in a grammar is local---the parser is ``in
+doubt'' only for a few tokens at a time. Therefore, the current data
+structure should generally be adequate. On LR(1) portions of a
+grammar, in particular, it is only slightly slower than with the
+deterministic LR(1) Bison parser.

+@cindex memory exhaustion
+@cindex memory management
+@cindex stack overflow
+@cindex parser stack overflow
+@cindex overflow of parser stack
+
+The Bison parser stack can run out of memory if too many tokens are shifted and
+not reduced. When this happens, the parser function @code{yyparse}
+calls @code{yyerror} and then returns 2.
+
+Because Bison parsers have growing stacks, hitting the upper limit
+usually results from using a right recursion instead of a left
+recursion, see @ref{Recursion, ,Recursive Rules}.
+
+@vindex YYMAXDEPTH
+By defining the macro @code{YYMAXDEPTH}, you can control how deep the
+parser stack can become before memory is exhausted. Define the
+macro with a value that is an integer. This value is the maximum number
+of tokens that can be shifted (and not reduced) before overflow.
+
+The stack space allowed is not necessarily allocated. If you specify a
+large value for @code{YYMAXDEPTH}, the parser normally allocates a small
+stack at first, and then makes it bigger by stages as needed. This
+increasing allocation happens automatically and silently. Therefore,
+you do not need to make @code{YYMAXDEPTH} painfully small merely to save
+space for ordinary inputs that do not need much stack.
+
+However, do not allow @code{YYMAXDEPTH} to be a value so large that
+arithmetic overflow could occur when calculating the size of the stack
+space. Also, do not allow @code{YYMAXDEPTH} to be less than
+@code{YYINITDEPTH}.
+
+@cindex default stack limit
+The default value of @code{YYMAXDEPTH}, if you do not define it, is
+10000.
+
+@vindex YYINITDEPTH
+You can control how much stack is allocated initially by defining the
+macro @code{YYINITDEPTH} to a positive integer. For the deterministic
+parser in C, this value must be a compile-time constant
+unless you are assuming C99 or some other target language or compiler
+that allows variable-length arrays. The default is 200.
+
+Do not allow @code{YYINITDEPTH} to be greater than @code{YYMAXDEPTH}.
+
+@c FIXME: C++ output.
+Because of semantic differences between C and C++, the deterministic
+parsers in C produced by Bison cannot grow when compiled
+by C++ compilers. In this precise case (compiling a C parser as C++) you are

+
+@node Error Recovery
+@chapter Error Recovery
+@cindex error recovery
+@cindex recovery from errors
+
+It is not usually acceptable to have a program terminate on a syntax
+error. For example, a compiler should recover sufficiently to parse the
+rest of the input file and check it for errors; a calculator should accept
+another expression.
+
+In a simple interactive command parser where each input is one line, it may
+be sufficient to allow @code{yyparse} to return 1 on error and have the
+caller ignore the rest of the input line when that happens (and then call
+@code{yyparse} again). But this is inadequate for a compiler, because it
+forgets all the syntactic context leading up to the error. A syntax error
+deep within a function in the compiler input should not cause the compiler
+to treat the following line like the beginning of a source file.
+
+@findex error
+You can define how to recover from a syntax error by writing rules to
+recognize the special token @code{error}. This is a terminal symbol that
+is always defined (you need not declare it) and reserved for error
+handling. The Bison parser generates an @code{error} token whenever a
+syntax error happens; if you have provided a rule to recognize this token
+in the current context, the parse can continue.
+
+For example:
+
+@example
+stmts:
+ /* empty string */
+| stmts '\n'
+| stmts exp '\n'
+| stmts error '\n'
+@end example
+
+The fourth rule in this example says that an error followed by a newline
+makes a valid addition to any @code{stmts}.
+
+What happens if a syntax error occurs in the middle of an @code{exp}? The
+error recovery rule, interpreted strictly, applies to the precise sequence
+of a @code{stmts}, an @code{error} and a newline. If an error occurs in
+the middle of an @code{exp}, there will probably be some additional tokens
+and subexpressions on the stack after the last @code{stmts}, and there
+will be tokens to read before the next newline. So the rule is not
+applicable in the ordinary way.
+
+But Bison can force the situation to fit the rule, by discarding part of
+the semantic context and part of the input. First it discards states
+and objects from the stack until it gets back to a state in which the
+@code{error} token is acceptable. (This means that the subexpressions
+already parsed are discarded, back to the last complete @code{stmts}.)
+At this point the @code{error} token can be shifted. Then, if the old
+lookahead token is not acceptable to be shifted next, the parser reads
+tokens and discards them until it finds a token which is acceptable. In
+this example, Bison reads and discards input until the next newline so
+that the fourth rule can apply. Note that discarded symbols are
+possible sources of memory leaks, see @ref{Destructor Decl, , Freeing
+Discarded Symbols}, for a means to reclaim this memory.
+
+The choice of error rules in the grammar is a choice of strategies for
+error recovery. A simple and useful strategy is simply to skip the rest of
+the current input line or current statement if an error is detected:
+
+@example
+stmt: error ';' /* On error, skip until ';' is read. */
+@end example
+
+It is also useful to recover to the matching close-delimiter of an
+opening-delimiter that has already been parsed. Otherwise the
+close-delimiter will probably appear to be unmatched, and generate another,
+spurious error message:
+
+@example
+primary:
+ '(' expr ')'
+| '(' error ')'
+@dots{}
+;
+@end example
+
+Error recovery strategies are necessarily guesses. When they guess wrong,
+one syntax error often leads to another. In the above example, the error
+recovery rule guesses that an error is due to bad input within one
+@code{stmt}. Suppose that instead a spurious semicolon is inserted in the
+middle of a valid @code{stmt}. After the error recovery rule recovers
+from the first error, another syntax error will be found straightaway,
+since the text following the spurious semicolon is also an invalid
+@code{stmt}.
+
+To prevent an outpouring of error messages, the parser will output no error
+message for another syntax error that happens shortly after the first; only
+after three consecutive input tokens have been successfully shifted will
+error messages resume.
+
+Note that rules which accept the @code{error} token may have actions, just
+as any other rules can.
+
+@findex yyerrok
+You can make error messages resume immediately by using the macro
+@code{yyerrok} in an action. If you do this in the error rule's action, no
+error messages will be suppressed. This macro requires no arguments;
+@samp{yyerrok;} is a valid C statement.
+
+@findex yyclearin
+The previous lookahead token is reanalyzed immediately after an error. If
+this is unacceptable, then the macro @code{yyclearin} may be used to clear
+this token. Write the statement @samp{yyclearin;} in the error rule's
+action.
+@xref{Action Features, ,Special Features for Use in Actions}.
+
+For example, suppose that on a syntax error, an error handling routine is
+called that advances the input stream to some point where parsing should
+once again commence. The next symbol returned by the lexical scanner is
+probably correct. The previous lookahead token ought to be discarded
+with @samp{yyclearin;}.
+
+@vindex YYRECOVERING
+The expression @code{YYRECOVERING ()} yields 1 when the parser
+is recovering from a syntax error, and 0 otherwise.
+Syntax error diagnostics are suppressed while recovering from a syntax
+error.
+
+@node Context Dependency
+@chapter Handling Context Dependencies
+
+The Bison paradigm is to parse tokens first, then group them into larger
+syntactic units. In many languages, the meaning of a token is affected by
+its context. Although this violates the Bison paradigm, certain techniques
+(known as @dfn{kludges}) may enable you to write Bison parsers for such
+languages.
+
+@menu
+* Semantic Tokens:: Token parsing can depend on the semantic context.
+* Lexical Tie-ins:: Token parsing can depend on the syntactic context.
+* Tie-in Recovery:: Lexical tie-ins have implications for how

+@end menu
+
+(Actually, ``kludge'' means any technique that gets its job done but is
+neither clean nor robust.)
+
+@node Semantic Tokens
+@section Semantic Info in Token Types
+
+The C language has a context dependency: the way an identifier is used
+depends on what its current meaning is. For example, consider this:
+
+@example
+foo (x);
+@end example
+
+This looks like a function call statement, but if @code{foo} is a typedef
+name, then this is actually a declaration of @code{x}. How can a Bison
+parser for C decide how to parse this input?
+
+The method used in GNU C is to have two different token types,
+@code{IDENTIFIER} and @code{TYPENAME}. When @code{yylex} finds an
+identifier, it looks up the current declaration of the identifier in order
+to decide which token type to return: @code{TYPENAME} if the identifier is
+declared as a typedef, @code{IDENTIFIER} otherwise.
+
+The grammar rules can then express the context dependency by the choice of
+token type to recognize. @code{IDENTIFIER} is accepted as an expression,
+but @code{TYPENAME} is not. @code{TYPENAME} can start a declaration, but
+@code{IDENTIFIER} cannot. In contexts where the meaning of the identifier
+is @emph{not} significant, such as in declarations that can shadow a
+typedef name, either @code{TYPENAME} or @code{IDENTIFIER} is
+accepted---there is one rule for each of the two token types.
+
+This technique is simple to use if the decision of which kinds of
+identifiers to allow is made at a place close to where the identifier is
+parsed. But in C this is not always so: C allows a declaration to
+redeclare a typedef name provided an explicit type has been specified
+earlier:
+
+@example
+typedef int foo, bar;
+int baz (void)
+@group
+@{
+ static bar (bar); /* @r{redeclare @code{bar} as static variable} */
+ extern foo foo (foo); /* @r{redeclare @code{foo} as function} */
+ return foo (bar);
+@}
+@end group
+@end example
+
+Unfortunately, the name being declared is separated from the declaration
+construct itself by a complicated syntactic structure---the ``declarator''.
+
+As a result, part of the Bison parser for C needs to be duplicated, with
+all the nonterminal names changed: once for parsing a declaration in
+which a typedef name can be redefined, and once for parsing a
+declaration in which that can't be done. Here is a part of the
+duplication, with actions omitted for brevity:
+
+@example
+@group
+initdcl:
+ declarator maybeasm '=' init
+| declarator maybeasm
+;
+@end group
+
+@group
+notype_initdcl:
+ notype_declarator maybeasm '=' init
+| notype_declarator maybeasm
+;
+@end group
+@end example
+
+@noindent
+Here @code{initdcl} can redeclare a typedef name, but @code{notype_initdcl}
+cannot. The distinction between @code{declarator} and
+@code{notype_declarator} is the same sort of thing.
+
+There is some similarity between this technique and a lexical tie-in
+(described next), in that information which alters the lexical analysis is
+changed during parsing by other parts of the program. The difference is
+here the information is global, and is used for other purposes in the
+program. A true lexical tie-in has a special-purpose flag controlled by
+the syntactic context.
+
+@node Lexical Tie-ins
+@section Lexical Tie-ins
+@cindex lexical tie-in
+
+One way to handle context-dependency is the @dfn{lexical tie-in}: a flag
+which is set by Bison actions, whose purpose is to alter the way tokens are
+parsed.
+
+For example, suppose we have a language vaguely like C, but with a special
+construct @samp{hex (@var{hex-expr})}. After the keyword @code{hex} comes
+an expression in parentheses in which all integers are hexadecimal. In
+particular, the token @samp{a1b} must be treated as an integer rather than
+as an identifier if it appears in that context. Here is how you can do it:
+
+@example
+@group
+%@{
+ int hexflag;
+ int yylex (void);
+ void yyerror (char const *);
+%@}
+%%
+@dots{}
+@end group
+@group
+expr:
+ IDENTIFIER
+| constant
+| HEX '(' @{ hexflag = 1; @}
+ expr ')' @{ hexflag = 0; $$ = $4; @}
+| expr '+' expr @{ $$ = make_sum ($1, $3); @}
+@dots{}
+;
+@end group
+
+@group
+constant:
+ INTEGER
+| STRING
+;
+@end group
+@end example
+
+@noindent
+Here we assume that @code{yylex} looks at the value of @code{hexflag}; when
+it is nonzero, all integers are parsed in hexadecimal, and tokens starting
+with letters are parsed as integers if possible.
+
+The declaration of @code{hexflag} shown in the prologue of the grammar
+file is needed to make it accessible to the actions (@pxref{Prologue,
+,The Prologue}). You must also write the code in @code{yylex} to obey
+the flag.
+
+@node Tie-in Recovery
+@section Lexical Tie-ins and Error Recovery
+
+Lexical tie-ins make strict demands on any error recovery rules you have.
+@xref{Error Recovery}.
+
+The reason for this is that the purpose of an error recovery rule is to
+abort the parsing of one construct and resume in some larger construct.
+For example, in C-like languages, a typical error recovery rule is to skip
+tokens until the next semicolon, and then start a new statement, like this:
+
+@example
+stmt:
+ expr ';'
+| IF '(' expr ')' stmt @{ @dots{} @}
+@dots{}
+| error ';' @{ hexflag = 0; @}
+;
+@end example
+
+If there is a syntax error in the middle of a @samp{hex (@var{expr})}
+construct, this error rule will apply, and then the action for the
+completed @samp{hex (@var{expr})} will never run. So @code{hexflag} would
+remain set for the entire rest of the input, or until the next @code{hex}
+keyword, causing identifiers to be misinterpreted as integers.
+
+To avoid this problem the error recovery rule itself clears @code{hexflag}.
+
+There may also be an error recovery rule that works within expressions.
+For example, there could be a rule which applies within parentheses
+and skips to the close-parenthesis:
+
+@example
+@group
+expr:
+ @dots{}
+| '(' expr ')' @{ $$ = $2; @}
+| '(' error ')'
+@dots{}
+@end group
+@end example
+
+If this rule acts within the @code{hex} construct, it is not going to abort
+that construct (since it applies to an inner level of parentheses within
+the construct). Therefore, it should not clear the flag: the rest of
+the @code{hex} construct should be parsed with the flag still in effect.
+
+What if there is an error recovery rule which might abort out of the
+@code{hex} construct or might not, depending on circumstances? There is no
+way you can write the action to determine whether a @code{hex} construct is
+being aborted or not. So if you are using a lexical tie-in, you had better
+make sure your error recovery rules are not of this kind. Each rule must
+be such that you can be sure that it always will, or always won't, have to
+clear the flag.

+Developing a parser can be a challenge, especially if you don't understand
+the algorithm (@pxref{Algorithm, ,The Bison Parser Algorithm}). This
+chapter explains how to generate and read the detailed description of the
+automaton, and how to enable and understand the parser run-time traces.

+@section Understanding Your Parser
+
+As documented elsewhere (@pxref{Algorithm, ,The Bison Parser Algorithm})
+Bison parsers are @dfn{shift/reduce automata}. In some cases (much more
+frequent than one would hope), looking at this automaton is required to
+tune or simply fix a parser. Bison provides two different
+representation of it, either textually or graphically (as a DOT file).
+
+The textual file is generated when the options @option{--report} or
+@option{--verbose} are specified, see @ref{Invocation, , Invoking
+Bison}. Its name is made by removing @samp{.tab.c} or @samp{.c} from
+the parser implementation file name, and adding @samp{.output}
+instead. Therefore, if the grammar file is @file{foo.y}, then the
+parser implementation file is called @file{foo.tab.c} by default. As
+a consequence, the verbose output file is called @file{foo.output}.
+
+The following grammar file, @file{calc.y}, will be used in the sequel:
+
+@example
+%token NUM STR
+%left '+' '-'
+%left '*'
+%%
+exp:
+ exp '+' exp
+| exp '-' exp
+| exp '*' exp
+| exp '/' exp
+| NUM
+;
+useless: STR;
+%%
+@end example
+
+@command{bison} reports:
+
+@example
+calc.y: warning: 1 nonterminal useless in grammar
+calc.y: warning: 1 rule useless in grammar
+calc.y:11.1-7: warning: nonterminal useless in grammar: useless
+calc.y:11.10-12: warning: rule useless in grammar: useless: STR
+calc.y: conflicts: 7 shift/reduce
+@end example
+
+When given @option{--report=state}, in addition to @file{calc.tab.c}, it
+creates a file @file{calc.output} with contents detailed below. The
+order of the output and the exact presentation might vary, but the
+interpretation is the same.
+
+@noindent
+@cindex token, useless
+@cindex useless token
+@cindex nonterminal, useless
+@cindex useless nonterminal
+@cindex rule, useless
+@cindex useless rule
+The first section reports useless tokens, nonterminals and rules. Useless
+nonterminals and rules are removed in order to produce a smaller parser, but
+useless tokens are preserved, since they might be used by the scanner (note
+the difference between ``useless'' and ``unused'' below):
+
+@example
+Nonterminals useless in grammar
+ useless
+
+Terminals unused in grammar
+ STR
+
+Rules useless in grammar
+ 6 useless: STR
+@end example
+
+@noindent
+The next section lists states that still have conflicts.
+
+@example
+State 8 conflicts: 1 shift/reduce
+State 9 conflicts: 1 shift/reduce
+State 10 conflicts: 1 shift/reduce
+State 11 conflicts: 4 shift/reduce
+@end example
+
+@noindent
+Then Bison reproduces the exact grammar it used:
+
+@example
+Grammar
+
+ 0 $accept: exp $end
+
+ 1 exp: exp '+' exp
+ 2 | exp '-' exp
+ 3 | exp '*' exp
+ 4 | exp '/' exp
+ 5 | NUM
+@end example
+
+@noindent
+and reports the uses of the symbols:
+
+@example
+@group
+Terminals, with rules where they appear
+
+$end (0) 0
+'*' (42) 3
+'+' (43) 1
+'-' (45) 2
+'/' (47) 4
+error (256)
+NUM (258) 5
+STR (259)
+@end group
+
+@group
+Nonterminals, with rules where they appear
+
+$accept (9)
+ on left: 0
+exp (10)
+ on left: 1 2 3 4 5, on right: 0 1 2 3 4
+@end group
+@end example
+
+@noindent
+@cindex item
+@cindex pointed rule
+@cindex rule, pointed
+Bison then proceeds onto the automaton itself, describing each state
+with its set of @dfn{items}, also known as @dfn{pointed rules}. Each
+item is a production rule together with a point (@samp{.}) marking
+the location of the input cursor.
+
+@example
+state 0
+
+ 0 $accept: . exp $end
+
+ NUM shift, and go to state 1
+
+ exp go to state 2
+@end example
+
+This reads as follows: ``state 0 corresponds to being at the very
+beginning of the parsing, in the initial rule, right before the start
+symbol (here, @code{exp}). When the parser returns to this state right
+after having reduced a rule that produced an @code{exp}, the control
+flow jumps to state 2. If there is no such transition on a nonterminal
+symbol, and the lookahead is a @code{NUM}, then this token is shifted onto
+the parse stack, and the control flow jumps to state 1. Any other
+lookahead triggers a syntax error.''
+
+@cindex core, item set
+@cindex item set core
+@cindex kernel, item set
+@cindex item set core
+Even though the only active rule in state 0 seems to be rule 0, the
+report lists @code{NUM} as a lookahead token because @code{NUM} can be
+at the beginning of any rule deriving an @code{exp}. By default Bison
+reports the so-called @dfn{core} or @dfn{kernel} of the item set, but if
+you want to see more detail you can invoke @command{bison} with
+@option{--report=itemset} to list the derived items as well:
+
+@example
+state 0
+
+ 0 $accept: . exp $end
+ 1 exp: . exp '+' exp
+ 2 | . exp '-' exp
+ 3 | . exp '*' exp
+ 4 | . exp '/' exp
+ 5 | . NUM
+
+ NUM shift, and go to state 1
+
+ exp go to state 2
+@end example
+
+@noindent
+In the state 1@dots{}
+
+@example
+state 1
+
+ 5 exp: NUM .
+
+ $default reduce using rule 5 (exp)
+@end example
+
+@noindent
+the rule 5, @samp{exp: NUM;}, is completed. Whatever the lookahead token
+(@samp{$default}), the parser will reduce it. If it was coming from
+state 0, then, after this reduction it will return to state 0, and will
+jump to state 2 (@samp{exp: go to state 2}).
+
+@example
+state 2
+
+ 0 $accept: exp . $end
+ 1 exp: exp . '+' exp
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ $end shift, and go to state 3
+ '+' shift, and go to state 4
+ '-' shift, and go to state 5
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+@end example
+
+@noindent
+In state 2, the automaton can only shift a symbol. For instance,
+because of the item @samp{exp: exp . '+' exp}, if the lookahead is
+@samp{+} it is shifted onto the parse stack, and the automaton
+jumps to state 4, corresponding to the item @samp{exp: exp '+' . exp}.
+Since there is no default action, any lookahead not listed triggers a syntax
+error.
+
+@cindex accepting state
+The state 3 is named the @dfn{final state}, or the @dfn{accepting
+state}:
+
+@example
+state 3
+
+ 0 $accept: exp $end .
+
+ $default accept
+@end example
+
+@noindent
+the initial rule is completed (the start symbol and the end-of-input were
+read), the parsing exits successfully.
+
+The interpretation of states 4 to 7 is straightforward, and is left to
+the reader.
+
+@example
+state 4
+
+ 1 exp: exp '+' . exp
+
+ NUM shift, and go to state 1
+
+ exp go to state 8
+
+
+state 5
+
+ 2 exp: exp '-' . exp
+
+ NUM shift, and go to state 1
+
+ exp go to state 9
+
+
+state 6
+
+ 3 exp: exp '*' . exp
+
+ NUM shift, and go to state 1
+
+ exp go to state 10
+
+
+state 7
+
+ 4 exp: exp '/' . exp
+
+ NUM shift, and go to state 1
+
+ exp go to state 11
+@end example
+
+As was announced in beginning of the report, @samp{State 8 conflicts:
+1 shift/reduce}:
+
+@example
+state 8
+
+ 1 exp: exp . '+' exp
+ 1 | exp '+' exp .
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+ '/' [reduce using rule 1 (exp)]
+ $default reduce using rule 1 (exp)
+@end example
+
+Indeed, there are two actions associated to the lookahead @samp{/}:
+either shifting (and going to state 7), or reducing rule 1. The
+conflict means that either the grammar is ambiguous, or the parser lacks
+information to make the right decision. Indeed the grammar is
+ambiguous, as, since we did not specify the precedence of @samp{/}, the
+sentence @samp{NUM + NUM / NUM} can be parsed as @samp{NUM + (NUM /
+NUM)}, which corresponds to shifting @samp{/}, or as @samp{(NUM + NUM) /
+NUM}, which corresponds to reducing rule 1.
+
+Because in deterministic parsing a single decision can be made, Bison
+arbitrarily chose to disable the reduction, see @ref{Shift/Reduce, ,
+Shift/Reduce Conflicts}. Discarded actions are reported between
+square brackets.
+
+Note that all the previous states had a single possible action: either
+shifting the next token and going to the corresponding state, or
+reducing a single rule. In the other cases, i.e., when shifting
+@emph{and} reducing is possible or when @emph{several} reductions are
+possible, the lookahead is required to select the action. State 8 is
+one such state: if the lookahead is @samp{*} or @samp{/} then the action
+is shifting, otherwise the action is reducing rule 1. In other words,
+the first two items, corresponding to rule 1, are not eligible when the
+lookahead token is @samp{*}, since we specified that @samp{*} has higher
+precedence than @samp{+}. More generally, some items are eligible only
+with some set of possible lookahead tokens. When run with
+@option{--report=lookahead}, Bison specifies these lookahead tokens:
+
+@example
+state 8
+
+ 1 exp: exp . '+' exp
+ 1 | exp '+' exp . [$end, '+', '-', '/']
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+ '/' [reduce using rule 1 (exp)]
+ $default reduce using rule 1 (exp)
+@end example
+
+Note however that while @samp{NUM + NUM / NUM} is ambiguous (which results in
+the conflicts on @samp{/}), @samp{NUM + NUM * NUM} is not: the conflict was
+solved thanks to associativity and precedence directives. If invoked with
+@option{--report=solved}, Bison includes information about the solved
+conflicts in the report:
+
+@example
+Conflict between rule 1 and token '+' resolved as reduce (%left '+').
+Conflict between rule 1 and token '-' resolved as reduce (%left '-').
+Conflict between rule 1 and token '*' resolved as shift ('+' < '*').
+@end example
+
+
+The remaining states are similar:
+
+@example
+@group
+state 9
+
+ 1 exp: exp . '+' exp
+ 2 | exp . '-' exp
+ 2 | exp '-' exp .
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+ '/' [reduce using rule 2 (exp)]
+ $default reduce using rule 2 (exp)
+@end group
+
+@group
+state 10
+
+ 1 exp: exp . '+' exp
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 3 | exp '*' exp .
+ 4 | exp . '/' exp
+
+ '/' shift, and go to state 7
+
+ '/' [reduce using rule 3 (exp)]
+ $default reduce using rule 3 (exp)
+@end group
+
+@group
+state 11
+
+ 1 exp: exp . '+' exp
+ 2 | exp . '-' exp
+ 3 | exp . '*' exp
+ 4 | exp . '/' exp
+ 4 | exp '/' exp .
+
+ '+' shift, and go to state 4
+ '-' shift, and go to state 5
+ '*' shift, and go to state 6
+ '/' shift, and go to state 7
+
+ '+' [reduce using rule 4 (exp)]
+ '-' [reduce using rule 4 (exp)]
+ '*' [reduce using rule 4 (exp)]
+ '/' [reduce using rule 4 (exp)]
+ $default reduce using rule 4 (exp)
+@end group
+@end example
+
+@noindent
+Observe that state 11 contains conflicts not only due to the lack of
+precedence of @samp{/} with respect to @samp{+}, @samp{-}, and
+@samp{*}, but also because the
+associativity of @samp{/} is not specified.

+@section Tracing Your Parser
+@findex yydebug
+@cindex debugging
+@cindex tracing the parser
+
+When a Bison grammar compiles properly but parses ``incorrectly'', the
+@code{yydebug} parser-trace feature helps figuring out why.
+
+@menu
+* Enabling Traces:: Activating run-time trace support
+* Mfcalc Traces:: Extending @code{mfcalc} to support traces
+* The YYPRINT Macro:: Obsolete interface for semantic value reports
+@end menu
+
+@node Enabling Traces
+@subsection Enabling Traces
+There are several means to enable compilation of trace facilities:
+
+@table @asis
+@item the macro @code{YYDEBUG}
+@findex YYDEBUG
+Define the macro @code{YYDEBUG} to a nonzero value when you compile the
+parser. This is compliant with POSIX Yacc. You could use
+@samp{-DYYDEBUG=1} as a compiler option or you could put @samp{#define
+YYDEBUG 1} in the prologue of the grammar file (@pxref{Prologue, , The
+Prologue}).
+
+If the @code{%define} variable @code{api.prefix} is used (@pxref{Multiple
+Parsers, ,Multiple Parsers in the Same Program}), for instance @samp{%define
+api.prefix x}, then if @code{CDEBUG} is defined, its value controls the
+tracing feature (enabled iff nonzero); otherwise tracing is enabled iff
+@code{YYDEBUG} is nonzero.
+
+@item the option @option{-t} (POSIX Yacc compliant)
+@itemx the option @option{--debug} (Bison extension)
+Use the @samp{-t} option when you run Bison (@pxref{Invocation, ,Invoking
+Bison}). With @samp{%define api.prefix c}, it defines @code{CDEBUG} to 1,
+otherwise it defines @code{YYDEBUG} to 1.
+
+@item the directive @samp{%debug}
+@findex %debug
+Add the @code{%debug} directive (@pxref{Decl Summary, ,Bison Declaration
+Summary}). This is a Bison extension, especially useful for languages that
+don't use a preprocessor. Unless POSIX and Yacc portability matter to you,
+this is the preferred solution.
+@end table
+
+We suggest that you always enable the debug option so that debugging is
+always possible.
+
+@findex YYFPRINTF
+The trace facility outputs messages with macro calls of the form
+@code{YYFPRINTF (stderr, @var{format}, @var{args})} where
+@var{format} and @var{args} are the usual @code{printf} format and variadic
+arguments. If you define @code{YYDEBUG} to a nonzero value but do not
+define @code{YYFPRINTF}, @code{<stdio.h>} is automatically included
+and @code{YYFPRINTF} is defined to @code{fprintf}.
+
+Once you have compiled the program with trace facilities, the way to
+request a trace is to store a nonzero value in the variable @code{yydebug}.
+You can do this by making the C code do it (in @code{main}, perhaps), or
+you can alter the value with a C debugger.
+
+Each step taken by the parser when @code{yydebug} is nonzero produces a
+line or two of trace information, written on @code{stderr}. The trace
+messages tell you these things:
+
+@itemize @bullet
+@item
+Each time the parser calls @code{yylex}, what kind of token was read.
+
+@item
+Each time a token is shifted, the depth and complete contents of the
+state stack (@pxref{Parser States}).
+
+@item
+Each time a rule is reduced, which rule it is, and the complete contents
+of the state stack afterward.
+@end itemize
+
+To make sense of this information, it helps to refer to the automaton
+description file (@pxref{Understanding, ,Understanding Your Parser}).
+This file shows the meaning of each state in terms of
+positions in various rules, and also what each state will do with each
+possible input token. As you read the successive trace messages, you
+can see that the parser is functioning according to its specification in
+the listing file. Eventually you will arrive at the place where
+something undesirable happens, and you will see which parts of the
+grammar are to blame.
+
+The parser implementation file is a C/C++/Java program and you can use
+debuggers on it, but it's not easy to interpret what it is doing. The
+parser function is a finite-state machine interpreter, and aside from
+the actions it executes the same code over and over. Only the values
+of variables show where in the grammar it is working.
+
+@node Mfcalc Traces
+@subsection Enabling Debug Traces for @code{mfcalc}
+
+The debugging information normally gives the token type of each token read,
+but not its semantic value. The @code{%printer} directive allows specify
+how semantic values are reported, see @ref{Printer Decl, , Printing
+Semantic Values}. For backward compatibility, Yacc like C parsers may also
+use the @code{YYPRINT} (@pxref{The YYPRINT Macro, , The @code{YYPRINT}
+Macro}), but its use is discouraged.
+
+As a demonstration of @code{%printer}, consider the multi-function
+calculator, @code{mfcalc} (@pxref{Multi-function Calc}). To enable run-time
+traces, and semantic value reports, insert the following directives in its
+prologue:
+
+@comment file: mfcalc.y: 2
+@example
+/* Generate the parser description file. */
+%verbose
+/* Enable run-time traces (yydebug). */
+%define parse.trace
+
+/* Formatting semantic values. */
+%printer @{ fprintf (yyoutput, "%s", $$->name); @} VAR;
+%printer @{ fprintf (yyoutput, "%s()", $$->name); @} FNCT;
+%printer @{ fprintf (yyoutput, "%g", $$); @} <val>;
+@end example
+
+The @code{%define} directive instructs Bison to generate run-time trace
+support. Then, activation of these traces is controlled at run-time by the
+@code{yydebug} variable, which is disabled by default. Because these traces
+will refer to the ``states'' of the parser, it is helpful to ask for the
+creation of a description of that parser; this is the purpose of (admittedly
+ill-named) @code{%verbose} directive.
+
+The set of @code{%printer} directives demonstrates how to format the
+semantic value in the traces. Note that the specification can be done
+either on the symbol type (e.g., @code{VAR} or @code{FNCT}), or on the type
+tag: since @code{<val>} is the type for both @code{NUM} and @code{exp}, this
+printer will be used for them.
+
+Here is a sample of the information provided by run-time traces. The traces
+are sent onto standard error.
+
+@example
+$ @kbd{echo 'sin(1-1)' | ./mfcalc -p}
+Starting parse
+Entering state 0
+Reducing stack by rule 1 (line 34):
+-> $$ = nterm input ()
+Stack now 0
+Entering state 1
+@end example
+
+@noindent
+This first batch shows a specific feature of this grammar: the first rule
+(which is in line 34 of @file{mfcalc.y} can be reduced without even having
+to look for the first token. The resulting left-hand symbol (@code{$$}) is
+a valueless (@samp{()}) @code{input} non terminal (@code{nterm}).
+
+Then the parser calls the scanner.
+@example
+Reading a token: Next token is token FNCT (sin())
+Shifting token FNCT (sin())
+Entering state 6
+@end example
+
+@noindent
+That token (@code{token}) is a function (@code{FNCT}) whose value is
+@samp{sin} as formatted per our @code{%printer} specification: @samp{sin()}.
+The parser stores (@code{Shifting}) that token, and others, until it can do
+something about it.
+
+@example
+Reading a token: Next token is token '(' ()
+Shifting token '(' ()
+Entering state 14
+Reading a token: Next token is token NUM (1.000000)
+Shifting token NUM (1.000000)
+Entering state 4
+Reducing stack by rule 6 (line 44):
+ $1 = token NUM (1.000000)
+-> $$ = nterm exp (1.000000)
+Stack now 0 1 6 14
+Entering state 24
+@end example
+
+@noindent
+The previous reduction demonstrates the @code{%printer} directive for
+@code{<val>}: both the token @code{NUM} and the resulting non-terminal
+@code{exp} have @samp{1} as value.
+
+@example
+Reading a token: Next token is token '-' ()
+Shifting token '-' ()
+Entering state 17
+Reading a token: Next token is token NUM (1.000000)
+Shifting token NUM (1.000000)
+Entering state 4
+Reducing stack by rule 6 (line 44):
+ $1 = token NUM (1.000000)
+-> $$ = nterm exp (1.000000)
+Stack now 0 1 6 14 24 17
+Entering state 26
+Reading a token: Next token is token ')' ()
+Reducing stack by rule 11 (line 49):
+ $1 = nterm exp (1.000000)
+ $2 = token '-' ()
+ $3 = nterm exp (1.000000)
+-> $$ = nterm exp (0.000000)
+Stack now 0 1 6 14
+Entering state 24
+@end example
+
+@noindent
+The rule for the subtraction was just reduced. The parser is about to
+discover the end of the call to @code{sin}.
+
+@example
+Next token is token ')' ()
+Shifting token ')' ()
+Entering state 31
+Reducing stack by rule 9 (line 47):
+ $1 = token FNCT (sin())
+ $2 = token '(' ()
+ $3 = nterm exp (0.000000)
+ $4 = token ')' ()
+-> $$ = nterm exp (0.000000)
+Stack now 0 1
+Entering state 11
+@end example
+
+@noindent
+Finally, the end-of-line allow the parser to complete the computation, and
+display its result.
+
+@example
+Reading a token: Next token is token '\n' ()
+Shifting token '\n' ()
+Entering state 22
+Reducing stack by rule 4 (line 40):
+ $1 = nterm exp (0.000000)
+ $2 = token '\n' ()
+@result{} 0
+-> $$ = nterm line ()
+Stack now 0 1
+Entering state 10
+Reducing stack by rule 2 (line 35):
+ $1 = nterm input ()
+ $2 = nterm line ()
+-> $$ = nterm input ()
+Stack now 0
+Entering state 1
+@end example
+
+The parser has returned into state 1, in which it is waiting for the next
+expression to evaluate, or for the end-of-file token, which causes the
+completion of the parsing.
+
+@example
+Reading a token: Now at end of input.
+Shifting token $end ()
+Entering state 2
+Stack now 0 1 2
+Cleanup: popping token $end ()
+Cleanup: popping nterm input ()
+@end example

+
+@node The YYPRINT Macro
+@subsection The @code{YYPRINT} Macro
+
+@findex YYPRINT
+Before @code{%printer} support, semantic values could be displayed using the

+@c ================================================= Invoking Bison
+
+@node Invocation
+@chapter Invoking Bison
+@cindex invoking Bison
+@cindex Bison invocation
+@cindex options for invoking Bison
+
+The usual way to invoke Bison is as follows:
+
+@example
+bison @var{infile}
+@end example
+
+Here @var{infile} is the grammar file name, which usually ends in
+@samp{.y}. The parser implementation file's name is made by replacing
+the @samp{.y} with @samp{.tab.c} and removing any leading directory.
+Thus, the @samp{bison foo.y} file name yields @file{foo.tab.c}, and
+the @samp{bison hack/foo.y} file name yields @file{foo.tab.c}. It's
+also possible, in case you are writing C++ code instead of C in your
+grammar file, to name it @file{foo.ypp} or @file{foo.y++}. Then, the
+output files will take an extension like the given one as input
+(respectively @file{foo.tab.cpp} and @file{foo.tab.c++}). This
+feature takes effect with all options that manipulate file names like
+@samp{-o} or @samp{-d}.
+
+For example :
+
+@example
+bison -d @var{infile.yxx}
+@end example
+@noindent
+will produce @file{infile.tab.cxx} and @file{infile.tab.hxx}, and
+
+@example
+bison -d -o @var{output.c++} @var{infile.y}

+@section Bison Options
+
+Bison supports both traditional single-letter options and mnemonic long
+option names. Long option names are indicated with @samp{--} instead of
+@samp{-}. Abbreviations for option names are allowed as long as they
+are unique. When a long option takes an argument, like
+@samp{--file-prefix}, connect the option name and the argument with
+@samp{=}.
+
+Here is a list of options that can be used with Bison, alphabetized by
+short option. It is followed by a cross key alphabetized by long
+option.
+
+@c Please, keep this ordered as in `bison --help'.
+@noindent
+Operations modes:
+@table @option
+@item -h
+@itemx --help
+Print a summary of the command-line options to Bison and exit.
+
+@item -V
+@itemx --version
+Print the version number of Bison and exit.
+
+@item --print-localedir
+Print the name of the directory containing locale-dependent data.
+
+@item --print-datadir
+Print the name of the directory containing skeletons and XSLT.
+
+@item -y
+@itemx --yacc
+Act more like the traditional Yacc command. This can cause different
+diagnostics to be generated, and may change behavior in other minor
+ways. Most importantly, imitate Yacc's output file name conventions,
+so that the parser implementation file is called @file{y.tab.c}, and
+the other outputs are called @file{y.output} and @file{y.tab.h}.
+Also, if generating a deterministic parser in C, generate
+@code{#define} statements in addition to an @code{enum} to associate
+token numbers with token names. Thus, the following shell script can
+substitute for Yacc, and the Bison distribution contains such a script
+for compatibility with POSIX:
+
+@example
+#! /bin/sh
+bison -y "$@@"
+@end example
+
+The @option{-y}/@option{--yacc} option is intended for use with
+traditional Yacc grammars. If your grammar uses a Bison extension
+like @samp{%glr-parser}, Bison might not be Yacc-compatible even if
+this option is specified.
+
+@item -W [@var{category}]
+@itemx --warnings[=@var{category}]
+Output warnings falling in @var{category}. @var{category} can be one
+of:
+@table @code
+@item midrule-values
+Warn about mid-rule values that are set but not used within any of the actions
+of the parent rule.
+For example, warn about unused @code{$2} in:
+
+@example
+exp: '1' @{ $$ = 1; @} '+' exp @{ $$ = $1 + $4; @};
+@end example
+
+Also warn about mid-rule values that are used but not set.
+For example, warn about unset @code{$$} in the mid-rule action in:
+
+@example
+exp: '1' @{ $1 = 1; @} '+' exp @{ $$ = $2 + $4; @};
+@end example
+
+These warnings are not enabled by default since they sometimes prove to
+be false alarms in existing grammars employing the Yacc constructs
+@code{$0} or @code{$-@var{n}} (where @var{n} is some positive integer).
+
+@item yacc
+Incompatibilities with POSIX Yacc.
+
+@item conflicts-sr
+@itemx conflicts-rr
+S/R and R/R conflicts. These warnings are enabled by default. However, if
+the @code{%expect} or @code{%expect-rr} directive is specified, an
+unexpected number of conflicts is an error, and an expected number of
+conflicts is not reported, so @option{-W} and @option{--warning} then have
+no effect on the conflict report.
+
+@item other
+All warnings not categorized above. These warnings are enabled by default.
+
+This category is provided merely for the sake of completeness. Future
+releases of Bison may move warnings from this category to new, more specific
+categories.
+
+@item all
+All the warnings.
+@item none
+Turn off all the warnings.
+@item error
+Treat warnings as errors.
+@end table
+
+A category can be turned off by prefixing its name with @samp{no-}. For
+instance, @option{-Wno-yacc} will hide the warnings about
+POSIX Yacc incompatibilities.
+@end table
+
+@noindent
+Tuning the parser:
+
+@table @option
+@item -t
+@itemx --debug
+In the parser implementation file, define the macro @code{YYDEBUG} to
+1 if it is not already defined, so that the debugging facilities are
+compiled. @xref{Tracing, ,Tracing Your Parser}.
+
+@item -D @var{name}[=@var{value}]
+@itemx --define=@var{name}[=@var{value}]
+@itemx -F @var{name}[=@var{value}]
+@itemx --force-define=@var{name}[=@var{value}]
+Each of these is equivalent to @samp{%define @var{name} "@var{value}"}
+(@pxref{%define Summary}) except that Bison processes multiple
+definitions for the same @var{name} as follows:
+
+@itemize
+@item
+Bison quietly ignores all command-line definitions for @var{name} except
+the last.
+@item
+If that command-line definition is specified by a @code{-D} or
+@code{--define}, Bison reports an error for any @code{%define}
+definition for @var{name}.
+@item
+If that command-line definition is specified by a @code{-F} or
+@code{--force-define} instead, Bison quietly ignores all @code{%define}
+definitions for @var{name}.
+@item
+Otherwise, Bison reports an error if there are multiple @code{%define}
+definitions for @var{name}.
+@end itemize
+
+You should avoid using @code{-F} and @code{--force-define} in your
+make files unless you are confident that it is safe to quietly ignore
+any conflicting @code{%define} that may be added to the grammar file.
+
+@item -L @var{language}
+@itemx --language=@var{language}
+Specify the programming language for the generated parser, as if
+@code{%language} was specified (@pxref{Decl Summary, , Bison Declaration
+Summary}). Currently supported languages include C, C++, and Java.
+@var{language} is case-insensitive.
+
+This option is experimental and its effect may be modified in future

+Parsers, ,Multiple Parsers in the Same Program}.
+
+@item -l
+@itemx --no-lines
+Don't put any @code{#line} preprocessor commands in the parser
+implementation file. Ordinarily Bison puts them in the parser
+implementation file so that the C compiler and debuggers will
+associate errors with your source file, the grammar file. This option
+causes them to associate errors with the parser implementation file,
+treating it as an independent source file in its own right.
+
+@item -S @var{file}
+@itemx --skeleton=@var{file}
+Specify the skeleton to use, similar to @code{%skeleton}
+(@pxref{Decl Summary, , Bison Declaration Summary}).
+
+@c You probably don't need this option unless you are developing Bison.
+@c You should use @option{--language} if you want to specify the skeleton for a
+@c different language, because it is clearer and because it will always
+@c choose the correct skeleton for non-deterministic or push parsers.
+
+If @var{file} does not contain a @code{/}, @var{file} is the name of a skeleton
+file in the Bison installation directory.
+If it does, @var{file} is an absolute file name or a file name relative to the

+
+@item -d
+This is the same as @code{--defines} except @code{-d} does not accept a

+focuses on the use of Bison, therefore the design of the various C++
+classes is very naive: no accessors, no encapsulation of members etc.
+We will use a Lex scanner, and more precisely, a Flex scanner, to

+actually easier to interface with.

+
+Of course the grammar is dedicated to arithmetics, a single
+expression, possibly preceded by variable assignments. An
+environment containing possibly predefined variables such as
+@code{one} and @code{two}, is exchanged with the parser. An example
+of valid input follows.
+

+
+@node Calc++ Parsing Driver
+@subsubsection Calc++ Parsing Driver
+@c - An env
+@c - A place to store error messages
+@c - A place for the result
+
+To support a pure interface with the parser (and the scanner) the
+technique of the ``parsing context'' is convenient: a structure
+containing all the data to exchange. Since, in addition to simply
+launch the parsing, there are several auxiliary tasks to execute (open
+the file for parsing, instantiate the parser etc.), we recommend
+transforming the simple parsing context structure into a fully blown
+@dfn{parsing driver} class.
+
+The declaration of this driver class, @file{calc++-driver.hh}, is as
+follows. The first part includes the CPP guard and imports the
+required standard library components, and the declaration of the parser
+class.
+
+@comment file: calc++-driver.hh
+@example
+#ifndef CALCXX_DRIVER_HH
+# define CALCXX_DRIVER_HH
+# include <string>
+# include <map>
+# include "calc++-parser.hh"
+@end example
+
+
+@noindent
+Then comes the declaration of the scanning function. Flex expects
+the signature of @code{yylex} to be defined in the macro
+@code{YY_DECL}, and the C++ parser expects it to be declared. We can
+factor both as follows.
+
+@comment file: calc++-driver.hh
+@example
+// Tell Flex the lexer's prototype ...
+# define YY_DECL \
+ yy::calcxx_parser::token_type \
+ yylex (yy::calcxx_parser::semantic_type* yylval, \
+ yy::calcxx_parser::location_type* yylloc, \
+ calcxx_driver& driver)
+// ... and declare it for the parser's sake.
+YY_DECL;
+@end example
+
+@noindent
+The @code{calcxx_driver} class is then declared with its most obvious
+members.
+
+@comment file: calc++-driver.hh
+@example
+// Conducting the whole scanning and parsing of Calc++.
+class calcxx_driver
+@{
+public:
+ calcxx_driver ();
+ virtual ~calcxx_driver ();
+
+ std::map<std::string, int> variables;
+
+ int result;
+@end example
+
+@noindent
+To encapsulate the coordination with the Flex scanner, it is useful to
+have two members function to open and close the scanning phase.
+
+@comment file: calc++-driver.hh
+@example
+ // Handling the scanner.
+ void scan_begin ();
+ void scan_end ();
+ bool trace_scanning;
+@end example
+
+@noindent
+Similarly for the parser itself.
+
+@comment file: calc++-driver.hh
+@example
+ // Run the parser. Return 0 on success.
+ int parse (const std::string& f);
+ std::string file;
+ bool trace_parsing;
+@end example
+
+@noindent
+To demonstrate pure handling of parse errors, instead of simply
+dumping them on the standard error output, we will pass them to the
+compiler driver using the following two member functions. Finally, we
+close the class declaration and CPP guard.
+
+@comment file: calc++-driver.hh
+@example
+ // Error handling.
+ void error (const yy::location& l, const std::string& m);
+ void error (const std::string& m);
+@};
+#endif // ! CALCXX_DRIVER_HH
+@end example
+
+The implementation of the driver is straightforward. The @code{parse}
+member function deserves some attention. The @code{error} functions
+are simple stubs, they should actually register the located error
+messages and set error state.

+@subsubsection Calc++ Parser
+
+The grammar file @file{calc++-parser.yy} starts by asking for the C++
+deterministic parser skeleton, the creation of the parser header file,
+and specifies the name of the parser class. Because the C++ skeleton
+changed several times, it is safer to require the version you designed
+the grammar for.
+
+@comment file: calc++-parser.yy
+@example
+%skeleton "lalr1.cc" /* -*- C++ -*- */
+%require "@value{VERSION}"
+%defines
+%define parser_class_name "calcxx_parser"
+@end example
+
+@noindent
+@findex %code requires
+Then come the declarations/inclusions needed to define the
+@code{%union}. Because the parser uses the parsing driver and
+reciprocally, both cannot include the header of the other. Because the
+driver's header needs detailed knowledge about the parser class (in
+particular its inner types), it is the parser's header which will simply
+use a forward declaration of the driver.
+@xref{%code Summary}.
+
+@comment file: calc++-parser.yy
+@example
+%code requires @{
+# include <string>
+class calcxx_driver;
+@}
+@end example
+
+@noindent
+The driver is passed by reference to the parser and to the scanner.
+This provides a simple but effective pure interface, not relying on
+global variables.

+@example
+// The parsing context.
+%parse-param @{ calcxx_driver& driver @}

+Then we request the location tracking feature, and initialize the
+first location's file name. Afterward new locations are computed
+relatively to the previous locations: the file name will be
+automatically propagated.

+avoid name clashes.
+

+@node Java Bison Interface
+@subsection Java Bison Interface
+@c - %language "Java"
+
+(The current Java interface is experimental and may evolve.
+More user feedback will help to stabilize it.)
+
+The Java parser skeletons are selected using the @code{%language "Java"}
+directive or the @option{-L java}/@option{--language=java} option.
+
+@c FIXME: Documented bug.
+When generating a Java parser, @code{bison @var{basename}.y} will
+create a single Java source file named @file{@var{basename}.java}
+containing the parser implementation. Using a grammar file without a
+@file{.y} suffix is currently broken. The basename of the parser
+implementation file can be changed by the @code{%file-prefix}
+directive or the @option{-p}/@option{--name-prefix} option. The
+entire parser implementation file name can be changed by the
+@code{%output} directive or the @option{-o}/@option{--output} option.
+The parser implementation file contains a single class for the parser.
+
+You can create documentation for generated parsers using Javadoc.
+
+Contrary to C parsers, Java parsers do not use global variables; the
+state of the parser is always local to an instance of the parser class.
+Therefore, all Java parsers are ``pure'', and the @code{%pure-parser}
+and @code{%define api.pure} directives does not do anything when used in
+Java.
+
+Push parsers are currently unsupported in Java and @code{%define
+api.push-pull} have no effect.
+
+GLR parsers are currently unsupported in Java. Do not use the
+@code{glr-parser} directive.
+
+No header file can be generated for Java parsers. Do not use the
+@code{%defines} directive or the @option{-d}/@option{--defines} options.
+
+@c FIXME: Possible code change.
+Currently, support for debugging and verbose errors are always compiled
+in. Thus the @code{%debug} and @code{%token-table} directives and the
+@option{-t}/@option{--debug} and @option{-k}/@option{--token-table}
+options have no effect. This may change in the future to eliminate
+unused code in the generated parser, so use @code{%debug} and
+@code{%verbose-error} explicitly if needed. Also, in the future the
+@code{%token-table} directive might enable a public interface to
+access the token names and codes.
+
+@node Java Semantic Values
+@subsection Java Semantic Values
+@c - No %union, specify type in %type/%token.
+@c - YYSTYPE
+@c - Printer and destructor
+
+There is no @code{%union} directive in Java parsers. Instead, the
+semantic values' types (class names) should be specified in the
+@code{%type} or @code{%token} directive:
+
+@example
+%type <Expression> expr assignment_expr term factor
+%type <Integer> number
+@end example
+
+By default, the semantic stack is declared to have @code{Object} members,
+which means that the class types you specify can be of any class.
+To improve the type safety of the parser, you can declare the common
+superclass of all the semantic values using the @code{%define stype}
+directive. For example, after the following declaration:
+
+@example
+%define stype "ASTNode"
+@end example
+
+@noindent
+any @code{%type} or @code{%token} specifying a semantic type which
+is not a subclass of ASTNode, will cause a compile-time error.
+
+@c FIXME: Documented bug.
+Types used in the directives may be qualified with a package name.
+Primitive data types are accepted for Java version 1.5 or later. Note
+that in this case the autoboxing feature of Java 1.5 will be used.
+Generic types may not be used; this is due to a limitation in the
+implementation of Bison, and may change in future releases.
+
+Java parsers do not support @code{%destructor}, since the language
+adopts garbage collection. The parser will try to hold references
+to semantic values for as little time as needed.
+
+Java parsers do not support @code{%printer}, as @code{toString()}
+can be used to print the semantic values. This however may change
+(in a backwards-compatible way) in future versions of Bison.
+
+
+@node Java Location Values
+@subsection Java Location Values
+@c - %locations
+@c - class Position
+@c - class Location
+
+When the directive @code{%locations} is used, the Java parser supports
+location tracking, see @ref{Tracking Locations}. An auxiliary user-defined
+class defines a @dfn{position}, a single point in a file; Bison itself
+defines a class representing a @dfn{location}, a range composed of a pair of
+positions (possibly spanning several files). The location class is an inner
+class of the parser; the name is @code{Location} by default, and may also be
+renamed using @code{%define location_type "@var{class-name}"}.
+
+The location class treats the position as a completely opaque value.
+By default, the class name is @code{Position}, but this can be changed
+with @code{%define position_type "@var{class-name}"}. This class must
+be supplied by the user.
+
+
+@deftypeivar {Location} {Position} begin
+@deftypeivarx {Location} {Position} end
+The first, inclusive, position of the range, and the first beyond.
+@end deftypeivar
+
+@deftypeop {Constructor} {Location} {} Location (Position @var{loc})
+Create a @code{Location} denoting an empty range located at a given point.
+@end deftypeop
+
+@deftypeop {Constructor} {Location} {} Location (Position @var{begin}, Position @var{end})
+Create a @code{Location} from the endpoints of the range.
+@end deftypeop
+
+@deftypemethod {Location} {String} toString ()
+Prints the range represented by the location. For this to work
+properly, the position class should override the @code{equals} and
+@code{toString} methods appropriately.

+@c - define parser_class_name
+@c - Ctor
+@c - parse, error, set_debug_level, debug_level, set_debug_stream,
+@c debug_stream.
+@c - Reporting errors
+
+The name of the generated parser class defaults to @code{YYParser}. The
+@code{YY} prefix may be changed using the @code{%name-prefix} directive
+or the @option{-p}/@option{--name-prefix} option. Alternatively, use
+@code{%define parser_class_name "@var{name}"} to give a custom name to
+the class. The interface of this class is detailed below.
+
+By default, the parser class has package visibility. A declaration
+@code{%define public} will change to public visibility. Remember that,
+according to the Java language specification, the name of the @file{.java}
+file should match the name of the class in this case. Similarly, you can
+use @code{abstract}, @code{final} and @code{strictfp} with the
+@code{%define} declaration to add other modifiers to the parser class.
+
+The Java package name of the parser class can be specified using the
+@code{%define package} directive. The superclass and the implemented
+interfaces of the parser class can be specified with the @code{%define
+extends} and @code{%define implements} directives.
+
+The parser class defines an inner class, @code{Location}, that is used
+for location tracking (see @ref{Java Location Values}), and a inner
+interface, @code{Lexer} (see @ref{Java Scanner Interface}). Other than
+these inner class/interface, and the members described in the interface
+below, all the other members and fields are preceded with a @code{yy} or
+@code{YY} prefix to avoid clashes with user code.

+@node Java Scanner Interface
+@subsection Java Scanner Interface
+@c - %code lexer
+@c - %lex-param
+@c - Lexer interface
+
+There are two possible ways to interface a Bison-generated Java parser
+with a scanner: the scanner may be defined by @code{%code lexer}, or
+defined elsewhere. In either case, the scanner has to implement the
+@code{Lexer} inner interface of the parser class.
+
+In the first case, the body of the scanner class is placed in
+@code{%code lexer} blocks. If you want to pass parameters from the
+parser constructor to the scanner constructor, specify them with
+@code{%lex-param}; they are passed before @code{%parse-param}s to the
+constructor.
+
+In the second case, the scanner has to implement the @code{Lexer} interface,
+which is defined within the parser class (e.g., @code{YYParser.Lexer}).
+The constructor of the parser object will then accept an object
+implementing the interface; @code{%lex-param} is not used in this
+case.
+
+In both cases, the scanner has to implement the following methods.
+
+@deftypemethod {Lexer} {void} yyerror (Location @var{loc}, String @var{msg})
+This method is defined by the user to emit an error message. The first
+parameter is omitted if location tracking is not active. Its type can be
+changed using @code{%define location_type "@var{class-name}".}
+@end deftypemethod
+
+@deftypemethod {Lexer} {int} yylex ()
+Return the next token. Its type is the return value, its semantic
+value and location are saved and returned by the their methods in the
+interface.
+
+Use @code{%define lex_throws} to specify any uncaught exceptions.
+Default is @code{java.io.IOException}.
+@end deftypemethod
+
+@deftypemethod {Lexer} {Position} getStartPos ()
+@deftypemethodx {Lexer} {Position} getEndPos ()
+Return respectively the first position of the last token that
+@code{yylex} returned, and the first position beyond it. These
+methods are not needed unless location tracking is active.
+
+The return type can be changed using @code{%define position_type
+"@var{class-name}".}
+@end deftypemethod
+
+@deftypemethod {Lexer} {Object} getLVal ()

+@subsection Special Features for Use in Java Actions

+Other analogous C action features are currently unavailable for Java.

+@node Java Differences
+@subsection Differences between C/C++ and Java Grammars
+
+The different structure of the Java language forces several differences
+between C/C++ grammars, and grammars designed for Java parsers. This
+section summarizes these differences.
+
+@itemize
+@item
+Java lacks a preprocessor, so the @code{YYERROR}, @code{YYACCEPT},
+@code{YYABORT} symbols (@pxref{Table of Symbols}) cannot obviously be
+macros. Instead, they should be preceded by @code{return} when they
+appear in an action. The actual definition of these symbols is
+opaque to the Bison grammar, and it might change in the future. The
+only meaningful operation that you can do, is to return them.
+@xref{Java Action Features}.
+
+Note that of these three symbols, only @code{YYACCEPT} and
+@code{YYABORT} will cause a return from the @code{yyparse}
+method@footnote{Java parsers include the actions in a separate
+method than @code{yyparse} in order to have an intuitive syntax that
+corresponds to these C macros.}.
+
+@item
+Java lacks unions, so @code{%union} has no effect. Instead, semantic
+values have a common base type: @code{Object} or as specified by
+@samp{%define stype}. Angle brackets on @code{%token}, @code{type},
+@code{$@var{n}} and @code{$$} specify subtypes rather than fields of
+an union. The type of @code{$$}, even with angle brackets, is the base
+type since Java casts are not allow on the left-hand side of assignments.
+Also, @code{$@var{n}} and @code{@@@var{n}} are not allowed on the
+left-hand side of assignments. @xref{Java Semantic Values}, and
+@ref{Java Action Features}.
+
+@item
+The prologue declarations have a different meaning than in C/C++ code.
+@table @asis
+@item @code{%code imports}
+blocks are placed at the beginning of the Java source code. They may
+include copyright notices. For a @code{package} declarations, it is
+suggested to use @code{%define package} instead.
+
+@item unqualified @code{%code}
+blocks are placed inside the parser class.
+
+@item @code{%code lexer}
+blocks, if specified, should include the implementation of the
+scanner. If there is no such block, the scanner can be any class
+that implements the appropriate interface (@pxref{Java Scanner
+Interface}).
+@end table
+
+Other @code{%code} blocks are not supported in Java parsers.
+In particular, @code{%@{ @dots{} %@}} blocks should not be used
+and may give an error in future versions of Bison.
+
+The epilogue has the same meaning as in C/C++ code and it can
+be used to define other classes used by the parser @emph{outside}
+the parser class.

+@section Memory Exhausted
+
+@quotation
+My parser returns with error with a @samp{memory exhausted}
+message. What can I do?
+@end quotation
+
+This question is already addressed elsewhere, see @ref{Recursion, ,Recursive
+Rules}.
+
+@node How Can I Reset the Parser
+@section How Can I Reset the Parser
+
+The following phenomenon has several symptoms, resulting in the
+following typical questions:
+
+@quotation
+I invoke @code{yyparse} several times, and on correct input it works
+properly; but when a parse error is found, all the other calls fail
+too. How can I reset the error flag of @code{yyparse}?
+@end quotation
+
+@noindent
+or
+
+@quotation
+My parser includes support for an @samp{#include}-like feature, in
+which case I run @code{yyparse} from @code{yyparse}. This fails
+although I did specify @samp{%define api.pure}.
+@end quotation
+
+These problems typically come not from Bison itself, but from
+Lex-generated scanners. Because these scanners use large buffers for
+speed, they might not notice a change of input file. As a
+demonstration, consider the following source file,
+@file{first-line.l}:
+
+@example
+@group
+%@{
+#include <stdio.h>
+#include <stdlib.h>
+%@}
+@end group
+%%
+.*\n ECHO; return 1;
+%%
+@group
+int
+yyparse (char const *file)
+@{
+ yyin = fopen (file, "r");
+ if (!yyin)
+ @{
+ perror ("fopen");
+ exit (EXIT_FAILURE);
+ @}
+@end group
+@group
+ /* One token only. */
+ yylex ();
+ if (fclose (yyin) != 0)
+ @{
+ perror ("fclose");
+ exit (EXIT_FAILURE);
+ @}
+ return 0;
+@}
+@end group
+
+@group
+int
+main (void)
+@{
+ yyparse ("input");
+ yyparse ("input");
+ return 0;
+@}
+@end group
+@end example
+
+@noindent
+If the file @file{input} contains
+
+@example
+input:1: Hello,
+input:2: World!
+@end example
+
+@noindent
+then instead of getting the first line twice, you get:
+
+@example
+$ @kbd{flex -ofirst-line.c first-line.l}
+$ @kbd{gcc -ofirst-line first-line.c -ll}
+$ @kbd{./first-line}
+input:1: Hello,
+input:2: World!
+@end example
+
+Therefore, whenever you change @code{yyin}, you must tell the
+Lex-generated scanner to discard its current buffer and switch to the
+new one. This depends upon your implementation of Lex; see its
+documentation for more. For Flex, it suffices to call
+@samp{YY_FLUSH_BUFFER} after each change to @code{yyin}. If your
+Flex-generated scanner needs to read from several input streams to
+handle features like include files, you might consider using Flex
+functions like @samp{yy_switch_to_buffer} that manipulate multiple
+input buffers.
+
+If your Flex-generated scanner uses start conditions (@pxref{Start
+conditions, , Start conditions, flex, The Flex Manual}), you might
+also want to reset the scanner's state, i.e., go back to the initial
+start condition, through a call to @samp{BEGIN (0)}.
+
+@node Strings are Destroyed
+@section Strings are Destroyed
+
+@quotation
+My parser seems to destroy old strings, or maybe it loses track of
+them. Instead of reporting @samp{"foo", "bar"}, it reports
+@samp{"bar", "bar"}, or even @samp{"foo\nbar", "bar"}.
+@end quotation
+
+This error is probably the single most frequent ``bug report'' sent to
+Bison lists, but is only concerned with a misunderstanding of the role
+of the scanner. Consider the following Lex code:
+
+@example
+@group
+%@{
+#include <stdio.h>
+char *yylval = NULL;
+%@}
+@end group
+@group
+%%
+.* yylval = yytext; return 1;
+\n /* IGNORE */
+%%
+@end group
+@group
+int
+main ()
+@{
+ /* Similar to using $1, $2 in a Bison action. */
+ char *fst = (yylex (), yylval);
+ char *snd = (yylex (), yylval);
+ printf ("\"%s\", \"%s\"\n", fst, snd);
+ return 0;
+@}
+@end group
+@end example
+
+If you compile and run this code, you get:
+
+@example
+$ @kbd{flex -osplit-lines.c split-lines.l}
+$ @kbd{gcc -osplit-lines split-lines.c -ll}
+$ @kbd{printf 'one\ntwo\n' | ./split-lines}
+"one
+two", "two"
+@end example
+
+@noindent
+this is because @code{yytext} is a buffer provided for @emph{reading}
+in the action, but if you want to keep it, you have to duplicate it
+(e.g., using @code{strdup}). Note that the output may depend on how
+your implementation of Lex handles @code{yytext}. For instance, when
+given the Lex compatibility option @option{-l} (which triggers the
+option @samp{%array}) Flex generates a different behavior:
+
+@example
+$ @kbd{flex -l -osplit-lines.c split-lines.l}
+$ @kbd{gcc -osplit-lines split-lines.c -ll}
+$ @kbd{printf 'one\ntwo\n' | ./split-lines}
+"two", "two"
+@end example
+
+
+@node Implementing Gotos/Loops
+@section Implementing Gotos/Loops
+
+@quotation
+My simple calculator supports variables, assignments, and functions,
+but how can I implement gotos, or loops?
+@end quotation
+
+Although very pedagogical, the examples included in the document blur
+the distinction to make between the parser---whose job is to recover
+the structure of a text and to transmit it to subsequent modules of
+the program---and the processing (such as the execution) of this
+structure. This works well with so called straight line programs,
+i.e., precisely those that have a straightforward execution model:
+execute simple instructions one after the others.
+
+@cindex abstract syntax tree
+@cindex AST
+If you want a richer model, you will probably need to use the parser
+to construct a tree that does represent the structure it has
+recovered; this tree is usually called the @dfn{abstract syntax tree},
+or @dfn{AST} for short. Then, walking through this tree,
+traversing it in various ways, will enable treatments such as its
+execution or its translation, which will result in an interpreter or a
+compiler.
+
+This topic is way beyond the scope of this manual, and the reader is
+invited to consult the dedicated literature.
+
+
+@node Multiple start-symbols
+@section Multiple start-symbols
+
+@quotation
+I have several closely related grammars, and I would like to share their
+implementations. In fact, I could use a single grammar but with
+multiple entry points.
+@end quotation
+
+Bison does not support multiple start-symbols, but there is a very
+simple means to simulate them. If @code{foo} and @code{bar} are the two
+pseudo start-symbols, then introduce two new tokens, say
+@code{START_FOO} and @code{START_BAR}, and use them as switches from the
+real start-symbol:
+
+@example
+%token START_FOO START_BAR;
+%start start;
+start:
+ START_FOO foo
+| START_BAR bar;
+@end example
+
+These tokens prevents the introduction of new conflicts. As far as the
+parser goes, that is all that is needed.
+
+Now the difficult part is ensuring that the scanner will send these
+tokens first. If your scanner is hand-written, that should be
+straightforward. If your scanner is generated by Lex, them there is
+simple means to do it: recall that anything between @samp{%@{ ... %@}}
+after the first @code{%%} is copied verbatim in the top of the generated
+@code{yylex} function. Make sure a variable @code{start_token} is
+available in the scanner (e.g., a global variable or using
+@code{%lex-param} etc.), and use the following:
+
+@example
+ /* @r{Prologue.} */
+%%
+%@{
+ if (start_token)
+ @{
+ int t = start_token;
+ start_token = 0;
+ return t;
+ @}
+%@}
+ /* @r{The rules.} */

+the bug is present in the latest version but not in a previous version,
+try to determine the most recent version which did not contain the bug.
+
+If the bug is parser-related, you should include the smallest grammar
+you can which demonstrates the bug. The grammar file should also be
+complete (i.e., I should be able to run it through Bison without having
+to edit or add anything). The smaller and simpler the grammar, the
+easier it will be to fix the bug.
+
+Include information about your compilation environment, including your
+operating system's name and version and your compiler's name and
+version. If you have trouble compiling, you should also include a
+transcript of the build session, starting with the invocation of
+`configure'. Depending on the nature of the bug, you may be asked to
+send additional files as well (such as `config.h' or `config.cache').

+
+It's not terribly involved. Basically, you would download a test

+that, you would submit either a bug report or a message saying that
+everything is okay. It is important to report successes as well as
+failures because test releases eventually become mainstream releases,
+but only if they are adequately tested. If no one tests, development is
+essentially halted.
+
+Beta testers are particularly needed for operating systems to which the

+The reduction that a parser should perform if the current parser state

+rules. @xref{Algorithm, ,The Bison Parser Algorithm}.
+
+@item Generalized LR (GLR)
+A parsing algorithm that can handle all context-free grammars, including those

+A minimal LR(1) parser table construction algorithm. That is, given any
+context-free grammar, IELR(1) generates parser tables with the full
+language-recognition power of canonical LR(1) but with nearly the same
+number of parser states as LALR(1). This reduction in parser states is
+often an order of magnitude. More importantly, because canonical LR(1)'s
+extra parser states may contain duplicate conflicts in the case of non-LR(1)
+grammars, the number of conflicts for IELR(1) is often an order of magnitude
+less as well. This can significantly reduce the complexity of developing a

+A parsing mechanism that fixes the problem of delayed syntax error
+detection, which is caused by LR state merging, default reductions, and the

+In computer languages, the semantics are specified by the actions

+An error encountered during parsing of an input stream due to invalid

+A basic, grammatically indivisible unit of a language. The symbol

+bison \- GNU Project parser generator (yacc replacement)
+
+[description]
+.I Bison
+is a parser generator in the style of
+.IR yacc (1).
+It should be upwardly compatible with input files designed
+for
+.IR yacc .
+.PP
+Input files should follow the
+.I yacc
+convention of ending in
+.BR .y .
+Unlike
+.IR yacc ,
+the generated files do not have fixed names, but instead use the prefix
+of the input file.
+Moreover, if you need to put
+.I C++
+code in the input file, you can end his name by a C++-like extension
+(.ypp or .y++), then bison will follow your extension to name the
+output file (.cpp or .c++).
+For instance, a grammar description file named
+.B parse.yxx
+would produce the generated parser in a file named
+.BR parse.tab.cxx ,
+instead of
+.IR yacc 's
+.B y.tab.c
+or old
+.I Bison
+version's
+.BR parse.tab.c .
+.PP
+This description of the options that can be given to
+.I bison
+is adapted from the node
+.B Invocation
+in the
+.B bison.texinfo
+manual, which should be taken as authoritative.
+.PP
+.I Bison
+supports both traditional single-letter options and mnemonic long
+option names. Long option names are indicated with
+.B \-\-
+instead of
+.BR \- .
+Abbreviations for option names are allowed as long as they
+are unique. When a long option takes an argument, like
+.BR \-\-file-prefix ,
+connect the option name and the argument with
+.BR = .

+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The ``Document'', below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as ``you''. You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject. (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, La@TeX{} input
+format, SGML or XML using a publicly available
+DTD, and standard-conforming simple HTML,
+PostScript or PDF designed for human modification. Examples
+of transparent image formats include PNG, XCF and
+JPG. Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, SGML or
+XML for which the DTD and/or processing tools are
+not generally available, and the machine-generated HTML,
+PostScript or PDF produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document). You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page. If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on. These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles. Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''. Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''. You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the

+
+@heading Preamble
+
+The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom
+to share and change all versions of a program---to make sure it remains
+free software for all its users. We, the Free Software Foundation,
+use the GNU General Public License for most of our software; it
+applies also to any other work released this way by its authors. You
+can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you
+have certain responsibilities if you distribute copies of the
+software, or if you modify it: responsibilities to respect the freedom
+of others.
+
+For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too,
+receive or can get the source code. And you must show them these
+terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the
+manufacturer can do so. This is fundamentally incompatible with the
+aim of protecting users' freedom to change the software. The
+systematic pattern of such abuse occurs in the area of products for
+individuals to use, which is precisely where it is most unacceptable.
+Therefore, we have designed this version of the GPL to prohibit the
+practice for those products. If such problems arise substantially in
+other domains, we stand ready to extend this provision to those
+domains in future versions of the GPL, as needed to protect the
+freedom of users.
+
+Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish
+to avoid the special danger that patents applied to a free program
+could make it effectively proprietary. To prevent this, the GPL
+assures that patents cannot be used to render the program non-free.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+@heading TERMS AND CONDITIONS
+
+@enumerate 0
+@item Definitions.
+
+``This License'' refers to version 3 of the GNU General Public License.
+
+``Copyright'' also means copyright-like laws that apply to other kinds
+of works, such as semiconductor masks.
+
+``The Program'' refers to any copyrightable work licensed under this
+License. Each licensee is addressed as ``you''. ``Licensees'' and
+``recipients'' may be individuals or organizations.
+
+To ``modify'' a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of
+an exact copy. The resulting work is called a ``modified version'' of
+the earlier work or a work ``based on'' the earlier work.
+
+A ``covered work'' means either the unmodified Program or a work based
+on the Program.
+
+To ``propagate'' a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+To ``convey'' a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user
+through a computer network, with no transfer of a copy, is not
+conveying.
+
+An interactive user interface displays ``Appropriate Legal Notices'' to
+the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+@item Source Code.
+
+The ``source code'' for a work means the preferred form of the work for
+making modifications to it. ``Object code'' means any non-source form
+of a work.
+
+A ``Standard Interface'' means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+The ``System Libraries'' of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+``Major Component'', in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+The ``Corresponding Source'' for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users can
+regenerate automatically from other parts of the Corresponding Source.
+
+The Corresponding Source for a work in source code form is that same
+work.
+
+@item Basic Permissions.
+
+All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not convey,
+without conditions so long as your license otherwise remains in force.
+You may convey covered works to others for the sole purpose of having
+them make modifications exclusively for you, or provide you with
+facilities for running those works, provided that you comply with the
+terms of this License in conveying all material for which you do not
+control copyright. Those thus making or running the covered works for
+you must do so exclusively on your behalf, under your direction and
+control, on terms that prohibit them from making any copies of your
+copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the
+conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+@item Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such
+circumvention is effected by exercising rights under this License with
+respect to the covered work, and you disclaim any intention to limit
+operation or modification of the work as a means of enforcing, against
+the work's users, your or third parties' legal rights to forbid
+circumvention of technological measures.
+
+@item Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+@item Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these
+conditions:
+
+@enumerate a
+@item
+The work must carry prominent notices stating that you modified it,
+and giving a relevant date.
+
+@item
+The work must carry prominent notices stating that it is released
+under this License and any conditions added under section 7. This
+requirement modifies the requirement in section 4 to ``keep intact all
+notices''.
+
+@item
+You must license the entire work, as a whole, under this License to
+anyone who comes into possession of a copy. This License will
+therefore apply, along with any applicable section 7 additional terms,
+to the whole of the work, and all its parts, regardless of how they
+are packaged. This License gives no permission to license the work in
+any other way, but it does not invalidate such permission if you have
+separately received it.
+
+@item
+If the work has interactive user interfaces, each must display
+Appropriate Legal Notices; however, if the Program has interactive
+interfaces that do not display Appropriate Legal Notices, your work
+need not make them do so.
+@end enumerate
+
+A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+``aggregate'' if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+@item Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of
+sections 4 and 5, provided that you also convey the machine-readable
+Corresponding Source under the terms of this License, in one of these
+ways:
+
+@enumerate a
+@item
+Convey the object code in, or embodied in, a physical product
+(including a physical distribution medium), accompanied by the
+Corresponding Source fixed on a durable physical medium customarily
+used for software interchange.
+
+@item
+Convey the object code in, or embodied in, a physical product
+(including a physical distribution medium), accompanied by a written
+offer, valid for at least three years and valid for as long as you
+offer spare parts or customer support for that product model, to give
+anyone who possesses the object code either (1) a copy of the
+Corresponding Source for all the software in the product that is
+covered by this License, on a durable physical medium customarily used
+for software interchange, for a price no more than your reasonable
+cost of physically performing this conveying of source, or (2) access
+to copy the Corresponding Source from a network server at no charge.
+
+@item
+Convey individual copies of the object code with a copy of the written
+offer to provide the Corresponding Source. This alternative is
+allowed only occasionally and noncommercially, and only if you
+received the object code with such an offer, in accord with subsection
+6b.
+
+@item
+Convey the object code by offering access from a designated place
+(gratis or for a charge), and offer equivalent access to the
+Corresponding Source in the same way through the same place at no
+further charge. You need not require recipients to copy the
+Corresponding Source along with the object code. If the place to copy
+the object code is a network server, the Corresponding Source may be
+on a different server (operated by you or a third party) that supports
+equivalent copying facilities, provided you maintain clear directions
+next to the object code saying where to find the Corresponding Source.
+Regardless of what server hosts the Corresponding Source, you remain
+obligated to ensure that it is available for as long as needed to
+satisfy these requirements.
+
+@item
+Convey the object code using peer-to-peer transmission, provided you
+inform other peers where the object code and Corresponding Source of
+the work are being offered to the general public at no charge under
+subsection 6d.
+
+@end enumerate
+
+A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+A ``User Product'' is either (1) a ``consumer product'', which means any
+tangible personal property which is normally used for personal,
+family, or household purposes, or (2) anything designed or sold for
+incorporation into a dwelling. In determining whether a product is a
+consumer product, doubtful cases shall be resolved in favor of
+coverage. For a particular product received by a particular user,
+``normally used'' refers to a typical or common use of that class of
+product, regardless of the status of the particular user or of the way
+in which the particular user actually uses, or expects or is expected
+to use, the product. A product is a consumer product regardless of
+whether the product has substantial commercial, industrial or
+non-consumer uses, unless such uses represent the only significant
+mode of use of the product.
+
+``Installation Information'' for a User Product means any methods,
+procedures, authorization keys, or other information required to
+install and execute modified versions of a covered work in that User
+Product from a modified version of its Corresponding Source. The
+information must suffice to ensure that the continued functioning of
+the modified object code is in no case prevented or interfered with
+solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or
+updates for a work that has been modified or installed by the
+recipient, or for the User Product in which it has been modified or
+installed. Access to a network may be denied when the modification
+itself materially and adversely affects the operation of the network
+or violates the rules and protocols for communication across the
+network.
+
+Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+@item Additional Terms.
+
+``Additional permissions'' are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders
+of that material) supplement the terms of this License with terms:
+
+@enumerate a
+@item
+Disclaiming warranty or limiting liability differently from the terms
+of sections 15 and 16 of this License; or
+
+@item
+Requiring preservation of specified reasonable legal notices or author
+attributions in that material or in the Appropriate Legal Notices
+displayed by works containing it; or
+
+@item
+Prohibiting misrepresentation of the origin of that material, or
+requiring that modified versions of such material be marked in
+reasonable ways as different from the original version; or
+
+@item
+Limiting the use for publicity purposes of names of licensors or
+authors of the material; or
+
+@item
+Declining to grant rights under trademark law for use of some trade
+names, trademarks, or service marks; or
+
+@item
+Requiring indemnification of licensors and authors of that material by
+anyone who conveys the material (or modified versions of it) with
+contractual assumptions of liability to the recipient, for any
+liability that these contractual assumptions directly impose on those
+licensors and authors.
+@end enumerate
+
+All other non-permissive additional terms are considered ``further
+restrictions'' within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions; the
+above requirements apply either way.
+
+@item Termination.
+
+You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+@item Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run
+a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+@item Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+An ``entity transaction'' is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+@item Patents.
+
+A ``contributor'' is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's ``contributor version''.
+
+A contributor's ``essential patent claims'' are all patent claims owned
+or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, ``control'' includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+In the following three paragraphs, a ``patent license'' is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To ``grant'' such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. ``Knowingly relying'' means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+A patent license is ``discriminatory'' if it does not include within the
+scope of its coverage, prohibits the exercise of, or is conditioned on
+the non-exercise of one or more of the rights that are specifically
+granted under this License. You may not convey a covered work if you
+are a party to an arrangement with a third party that is in the
+business of distributing software, under which you make payment to the
+third party based on the extent of your activity of conveying the
+work, and under which the third party grants, to any of the parties
+who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by
+you (or copies made from those copies), or (b) primarily for and in
+connection with specific products or compilations that contain the
+covered work, unless you entered into that arrangement, or that patent
+license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+@item No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey
+a covered work so as to satisfy simultaneously your obligations under
+this License and any other pertinent obligations, then as a
+consequence you may not convey it at all. For example, if you agree
+to terms that obligate you to collect a royalty for further conveying
+from those to whom you convey the Program, the only way you could
+satisfy both those terms and this License would be to refrain entirely
+from conveying the Program.
+
+@item Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+@item Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions
+of the GNU General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies that a certain numbered version of the GNU General Public
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that numbered version or
+of any later version published by the Free Software Foundation. If
+the Program does not specify a version number of the GNU General
+Public License, you may choose any version ever published by the Free
+Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions
+of the GNU General Public License can be used, that proxy's public
+statement of acceptance of a version permanently authorizes you to
+choose that version for the Program.
+
+Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+@item Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT
+WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
+LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
+A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
+PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
+DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+@item Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
+CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
+ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
+NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
+LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
+TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+@item Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+

+
+@heading END OF TERMS AND CONDITIONS
+
+@heading How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the ``copyright'' line and a pointer to where the full notice is found.
+
+@smallexample
+@var{one line to give the program's name and a brief idea of what it does.}
+Copyright (C) @var{year} @var{name of author}
+
+This program is free software: you can redistribute it and/or modify
+it under the terms of the GNU General Public License as published by
+the Free Software Foundation, either version 3 of the License, or (at
+your option) any later version.
+
+This program is distributed in the hope that it will be useful, but
+WITHOUT ANY WARRANTY; without even the implied warranty of
+MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+General Public License for more details.
+
+You should have received a copy of the GNU General Public License
+along with this program. If not, see @url{http://www.gnu.org/licenses/}.
+@end smallexample
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+@smallexample
+@var{program} Copyright (C) @var{year} @var{name of author}
+This program comes with ABSOLUTELY NO WARRANTY; for details type @samp{show w}.
+This is free software, and you are welcome to redistribute it
+under certain conditions; type @samp{show c} for details.
+@end smallexample
+
+The hypothetical commands @samp{show w} and @samp{show c} should show
+the appropriate parts of the General Public License. Of course, your
+program's commands might be different; for a GUI interface, you would
+use an ``about box''.
+
+You should also get your employer (if you work as a programmer) or school,
+if any, to sign a ``copyright disclaimer'' for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+@url{http://www.gnu.org/licenses/}.
+
+The GNU General Public License does not permit incorporating your
+program into proprietary programs. If your program is a subroutine
+library, you may consider it more useful to permit linking proprietary
+applications with the library. If this is what you want to do, use
+the GNU Lesser General Public License instead of this License. But
+first, please read @url{http://www.gnu.org/philosophy/why-not-lgpl.html}.

+%***********************
+
+To use Bison, type: \kbd{bison {\it filename}}
+
+Options can be used as: \kbd{bison {\it options} {\it filename}}
+
+\section{Command Line Options}
+%*****************************
+
+\key{Display usage information.} {-h}
+\key{Display version information.} {-V}
+\key{Generate token and {\tt YYSTYPE} definitions.} {-d}
+\key{Prepend a prefix to external symbols.} {-p {\it prefix}}

+\key{Verbose description of the parser.} {-v}
+\key{Emulate {\tt yacc} (generate {\tt y.tab.*} files).} {-y}
+
+\vskip .10truein
+{\bf Note:} The token and {\tt YYSTYPE} definitions are generated
+to a file called {\tt y.tab.h} if the {\tt -y} option is used,
+otherwise it will have the format {\tt {\it name}.tab.h}, where
+{\it name} is the leading part of the parser definition filename.
+
+\section{Definitions}
+%********************
+
+\key{Declare a terminal symbol.}{\%token <{\it t\/}>

+
+\key{Tell {\tt bison} the data type of symbols.}
+ {\%type <{\it t\/}> {\it s1}\dots{\it sn}}
+
+\vskip .10truein
+
+In the above, {\it t} is a {\it type} defined in the {\tt \%union}
+definition, {\it n} is a {\it terminal} symbol name, {\it m} is a
+{\it non-terminal} symbol name, and {\it association} can be one of
+{\tt \%left}, {\tt \%right}, or {\tt \%nonassoc}.
+
+\vskip .10truein
+
+The {\tt <{\it t\/}>} after {\tt \%token, \%left, \%right} and {\tt
+ \%nonassoc} is optional. Additionally, precedence may be overridden
+in the rules with {\tt \%prec} commands.
+
+\section{Parser Definition Files}
+%*********************************
+
+The general form for a parser definition is:
+
+\begincexample
+\{\%
+ /* Initial C code. */
+\%\}
+
+ {\it Token and type definitions}
+
+\%\%
+
+ Rule definition 1
+ \vdots
+ Rule definition {\it n}
+
+\%\%
+
+ /* Other C code. */
+\endcexample
+
+
+% Decrease standard baselineskip for the second page
+ \baselineskip = .9\baselineskip
+
+\section {Rule definitions}
+%**************************
+
+Rules take the form:
+
+\vskip -\baselineskip
+\beginexample
+ non-terminal : {\it statement} 1
+ | {\it statement} 2
+ \vdots
+ | {\it statement n}
+ ;
+\endexample
+
+Where {\it statements} can be either empty, or contain
+a mixture of C code (enclosed in {\tt \{...\}}), and the
+symbols that make up the non-terminal. For example:
+
+\vskip -\baselineskip
+\beginexample
+ expression : number '$+$' number \{ \$\$ $=$ \$1 $+$ \$3 \}
+ | number '$-$' number \{ \$\$ $=$ \$1 $-$ \$3 \}
+ | number '$/$' number \{ \$\$ $=$ \$1 $/$ \$3 \}
+ | number '$*$' number \{ \$\$ $=$ \$1 $*$ \$3 \}
+ ;
+\endexample
+
+For altering the precedence of a symbol use:
+\vskip -\baselineskip
+
+\beginexample
+ \%prec name
+\endexample
+
+For example:
+\vskip -\baselineskip
+\beginexample
+ foo : gnu bar gnu \%prec bar

+.NOEXPORT:

+* bench.pl
+A primitive Perl script to run benches. Currently its only bench is
+the usual calculator: it has a lightweight processing part (but not
+null), so it is really emphasizing the cost of the whole parsing
+(including scanning and I/O).
+
+Set the envvars BISON and CC to the programs and flags you want to
+use. They default to bison and gcc. To run a non-installed bison
+from a tarball built in _build, I suggest the following.
+
+ BISON=_build/tests/bison CC='gcc -O2' ./bench.pl
+
+(The _build/tests/bison wrapper makes sure that _build/src/bison will
+use the tarballs' skeletons, not those already installed as a
+straightforward use of _build/src/bison would.)

+ # Darwin 7.5 has nl_langinfo(CODESET), but sometimes its value is
+ # useless:
+ # - It returns the empty string when LANG is set to a locale of the
+ # form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
+ # LC_CTYPE file.
+ # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
+ # the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
+ # - The documentation says:
+ # "... all code that calls BSD system routines should ensure
+ # that the const *char parameters of these routines are in UTF-8
+ # encoding. All BSD system functions expect their string
+ # parameters to be in UTF-8 encoding and nothing else."
+ # It also says
+ # "An additional caveat is that string parameters for files,
+ # paths, and other file-system entities must be in canonical
+ # UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+ # characters are decomposed ..."
+ # but this is not true: You can pass non-decomposed UTF-8 strings
+ # to file system functions, and it is the OS which will convert
+ # them to decomposed UTF-8 before accessing the file system.
+ # - The Apple Terminal application displays UTF-8 by default.
+ # - However, other applications are free to use different encodings:
+ # - xterm uses ISO-8859-1 by default.
+ # - TextEdit uses MacRoman by default.
+ # We prefer UTF-8 over decomposed UTF-8-MAC because one should
+ # minimize the use of decomposed Unicode. Unfortunately, through the
+ # Darwin file system, decomposed UTF-8 strings are leaked into user
+ # space nevertheless.
+ # Then there are also the locales with encodings other than US-ASCII
+ # and UTF-8. These locales can be occasionally useful to users (e.g.
+ # when grepping through ISO-8859-1 encoded text files), when all their

+/* The i386 floating point hardware (the 387 compatible FPU, not the modern
+ SSE/SSE2 hardware) has a controllable rounding precision. It is specified
+ through the 'PC' bits in the FPU control word ('fctrl' register). (See
+ the GNU libc i386 <fpu_control.h> header for details.)
+
+ On some platforms, such as Linux or Solaris, the default precision setting
+ is set to "extended precision". This means that 'long double' instructions
+ operate correctly, but 'double' computations often produce slightly
+ different results as on strictly IEEE 754 conforming systems.
+
+ On some platforms, such as NetBSD, the default precision is set to
+ "double precision". This means that 'long double' instructions will operate
+ only as 'double', i.e. lead to wrong results. Similarly on FreeBSD 6.4, at
+ least for the division of 'long double' numbers.
+
+ The FPU control word is under control of the application, i.e. it is
+ not required to be set either way by the ABI. (In fact, the i386 ABI
+ http://refspecs.freestandards.org/elf/abi386-4.pdf page 3-12 = page 38
+ is not clear about it. But in any case, gcc treats the control word
+ like a "preserved" register: it emits code that assumes that the control
+ word is preserved across calls, and it restores the control word at the
+ end of functions that modify it.)
+
+ See Vincent Lefèvre's page http://www.vinc17.org/research/extended.en.html
+ for a good explanation.
+ See http://www.uwsg.iu.edu/hypermail/linux/kernel/0103.0/0453.html for

+
+ If an element of ARGV starts with '-', and is not exactly "-" or "--",
+ then it is an option element. The characters of this element
+ (aside from the initial '-') are option characters. If 'getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If 'getopt' finds another option character, it returns that character,
+ updating 'optind' and 'nextchar' so that the next call to 'getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, 'getopt' returns -1.
+ Then 'optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set 'opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in 'optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in 'optarg', otherwise 'optarg' is set to zero.
+
+ If OPTSTRING starts with '-' or '+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ Long-named options begin with '--' instead of '-'.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the same ARGV-element, separated
+ from the option name by a '=', or else the in next ARGV-element.
+ When 'getopt' finds a long-named option, it returns 0 if that option's
+ 'flag' field is nonzero, the value of the option's 'val' field
+ if the 'flag' field is zero.
+
+ The elements of ARGV aren't really const, because we permute them.
+ But we pretend they're const in the prototype to be compatible
+ with other systems.
+
+ LONGOPTS is a vector of 'struct option' terminated by an
+ element containing a name which is zero.
+
+ LONGIND returns the index in LONGOPT of the long-named option found.
+ It is only valid when a long-named option has been found by the most
+ recent call.

+ function, or just "hasher" for short) into a number (or "slot") between 0

+ A good "hasher" function will distribute entries rather evenly in buckets.
+ In the ideal case, the length of each bucket is roughly the number of

+ yielding shorter chains, *given* the "hasher" function behaves properly.
+
+ Long buckets slow down the lookup algorithm. One might use big hash table
+ sizes in hope to reduce the average length of buckets, but this might
+ become inordinate, as unused slots in the hash table take some space. The

+ 2) ease of maintenance, i.e. the maintainer needs not know all details
+ of the ISO C 99 standard,
+ 3) don't fail grossly if the input is not in the encoding set by the
+ locale, because often different encodings are in use in the same
+ countries (ISO-8859-1/UTF-8, EUC-JP/Shift_JIS, ...),
+ 4) fast in the case of ASCII characters,
+ 5) portability, i.e. don't make unportable assumptions about wchar_t.
+
+ Multibyte characters are only accessed through the mb* macros.
+
+ mb_ptr (mbc)

+
+ mb_equal (mbc1, mbc2)
+ returns true if mbc1 and mbc2 are equal.

+/* The macros in this file implement forward iteration through a
+ multi-byte string, without knowing its length a-priori.
+
+ With these macros, an iteration loop that looks like
+
+ char *iter;
+ for (iter = buf; *iter != '\0'; iter++)
+ {
+ do_something (*iter);
+ }
+
+ becomes
+
+ mbui_iterator_t iter;
+ for (mbui_init (iter, buf); mbui_avail (iter); mbui_advance (iter))
+ {
+ do_something (mbui_cur_ptr (iter), mb_len (mbui_cur (iter)));
+ }
+
+ The benefit of these macros over plain use of mbrtowc is:
+ - Handling of invalid multibyte sequences is possible without
+ making the code more complicated, while still preserving the
+ invalid multibyte sequences.
+
+ Compared to mbiter.h, the macros here don't need to know the string's
+ length a-priori. The downside is that at each step, the look-ahead
+ that guards against overrunning the terminating '\0' is more expensive.
+ The mbui_* macros are therefore suitable when there is a high probability
+ that only the first few multibyte characters need to be inspected.
+ Whereas the mbi_* macros are better if usually the iteration runs
+ through the entire string.
+
+ mbui_iterator_t
+ is a type usable for variable declarations.
+
+ mbui_init (iter, startptr)
+ initializes the iterator, starting at startptr.
+
+ mbui_avail (iter)
+ returns true if there are more multibyte characters available before
+ the end of string is reached. In this case, mbui_cur (iter) is
+ initialized to the next multibyte character.
+
+ mbui_advance (iter)
+ advances the iterator by one multibyte character.
+
+ mbui_cur (iter)
+ returns the current multibyte character, of type mbchar_t. All the
+ macros defined in mbchar.h can be used on it.
+
+ mbui_cur_ptr (iter)
+ return a pointer to the beginning of the current multibyte character.
+
+ mbui_reloc (iter, ptrdiff)
+ relocates iterator when the string is moved by ptrdiff bytes.
+
+ mbui_copy (&destiter, &srciter)
+ copies srciter to destiter.
+
+ Here are the function prototypes of the macros.

+ 2. & ~longword1.
+ 3. & a mask consisting of 0x80 in every byte.
+ Consider what happens in each byte:
+ - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+ and step 3 transforms it into 0x80. A carry can also be propagated
+ to more significant bytes.
+ - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+ position k (0 <= k <= 7); so the lowest k bits are 0. After step 1,
+ the byte ends in a single bit of value 0 and k bits of value 1.
+ After step 2, the result is just k bits of value 1: 2^k - 1. After
+ step 3, the result is 0. And no carry is produced.
+ So, if longword1 has only non-zero bytes, tmp is zero.
+ Whereas if longword1 has a zero byte, call j the position of the least
+ significant zero byte. Then the result has a zero at positions 0, ...,
+ j-1 and a 0x80 at position j. We cannot predict the result at the more
+ significant bytes (positions j+1..3), but it does not matter since we
+ already have a non-zero bit at position 8*j+7.

+/* Summary:
+
+All the apparent functions defined here are macros. The idea
+is that you would use these pre-tested macros to solve a
+very specific set of problems, and they would run fast.
+Caution: no side-effects in arguments please!! They may be
+evaluated MANY times!!
+
+These macros operate a stack of objects. Each object starts life
+small, and may grow to maturity. (Consider building a word syllable
+by syllable.) An object can move while it is growing. Once it has
+been "finished" it never changes address again. So the "top of the
+stack" is typically an immature growing object, while the rest of the
+stack is of mature, fixed size and fixed address objects.
+
+These routines grab large chunks of memory, using a function you
+supply, called 'obstack_chunk_alloc'. On occasion, they free chunks,
+by calling 'obstack_chunk_free'. You must define them and declare
+them before using any obstack macros.
+
+Each independent stack is represented by a 'struct obstack'.
+Each of the obstack macros expects a pointer to such a structure
+as the first argument.
+
+One motivation for this package is the problem of growing char strings
+in symbol tables. Unless you are "fascist pig with a read-only mind"
+--Gosper's immortal quote from HAKMEM item 154, out of context--you
+would not like to put any arbitrary upper limit on the length of your
+symbols.
+
+In practice this often means you will build many short symbols and a
+few long symbols. At the time you are reading a symbol you don't know
+how long it is. One traditional method is to read a symbol into a
+buffer, realloc()ating the buffer every time you try to read a symbol
+that is longer than the buffer. This is beaut, but you still will
+want to copy the symbol from the buffer to a more permanent
+symbol-table entry say about half the time.
+
+With obstacks, you can work differently. Use one obstack for all symbol
+names. As you read a symbol, grow the name in the obstack gradually.
+When the name is complete, finalize it. Then, if the symbol exists already,
+free the newly read name.
+
+The way we do this is to take a large chunk, allocating memory from
+low addresses. When you want to build a symbol in the chunk you just
+add chars above the current "high water mark" in the chunk. When you
+have finished adding chars, because you got to the end of the symbol,
+you know how long the chars are, and you can create a new object.
+Mostly the chars will not burst over the highest address of the chunk,
+because you would typically expect a chunk to be (say) 100 times as
+long as an average object.
+
+In case that isn't clear, when we have enough chars to make up
+the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
+so we just point to it where it lies. No moving of chars is
+needed and this is the second win: potentially long strings need
+never be explicitly shuffled. Once an object is formed, it does not
+change its address during its lifetime.
+
+When the chars burst over a chunk boundary, we allocate a larger
+chunk, and then copy the partly formed object from the end of the old
+chunk to the beginning of the new larger chunk. We then carry on
+accreting characters to the end of the object as we normally would.
+
+A special macro is provided to add a single char at a time to a
+growing object. This allows the use of register variables, which
+break the ordinary 'growth' macro.
+
+Summary:
+ We allocate large chunks.
+ We carve out one object at a time from the current chunk.
+ Once carved, an object never moves.
+ We are free to append data of any size to the currently
+ growing object.
+ Exactly one object is growing in an obstack at any one time.
+ You can run one obstack per control block.
+ You may have as many control blocks as you dare.
+ Because of the way we do it, you can "unwind" an obstack
+ back to a previous state. (You may remove objects much
+ as you would with a stack.)

+ - We don't implement SA_ONSTACK, because sigaltstack() is not present.
+ - We ignore SA_RESTART, because blocking native Windows API calls are

+ - We don't implement SA_SIGINFO because it is impossible to do so

+ They return the process id of the subprocess. They also return in fd[]
+ one or two file descriptors for communication with the subprocess.
+ If the subprocess creation fails: if exit_on_error is true, the main
+ process exits with an error message; otherwise, an error message is given
+ if null_stderr is false, then -1 is returned, with errno set, and fd[]
+ remain uninitialized.
+
+ After finishing communication, the caller should call wait_subprocess()
+ to get rid of the subprocess in the process table.
+
+ If slave_process is true, the child process will be terminated when its
+ creator receives a catchable fatal signal or exits normally. If
+ slave_process is false, the child process will continue running in this
+ case, until it is lucky enough to attempt to communicate with its creator
+ and thus get a SIGPIPE signal.
+
+ If exit_on_error is false, a child process id of -1 should be treated the
+ same way as a subprocess which accepts no input, produces no output and
+ terminates with exit code 127. Why? Some errors during posix_spawnp()
+ cause the function posix_spawnp() to return an error code; some other
+ errors cause the subprocess to exit with return code 127. It is
+ implementation dependent which error is reported which way. The caller
+ must treat both cases as equivalent.
+
+ It is recommended that no signal is blocked or ignored (i.e. have a
+ signal handler with value SIG_IGN) while any of these functions is called.
+ The reason is that child processes inherit the mask of blocked signals
+ from their parent (both through posix_spawn() and fork()/exec());
+ likewise, signals ignored in the parent are also ignored in the child
+ (except possibly for SIGCHLD). And POSIX:2001 says [in the description
+ of exec()]:
+ "it should be noted that many existing applications wrongly
+ assume that they start with certain signals set to the default
+ action and/or unblocked. In particular, applications written
+ with a simpler signal model that does not include blocking of
+ signals, such as the one in the ISO C standard, may not behave
+ properly if invoked with some signals blocked. Therefore, it is
+ best not to block or ignore signals across execs without explicit
+ reason to do so, and especially not to block signals across execs
+ of arbitrary (not closely co-operating) programs." */

+/* Usage suggestions:
+
+ Programs that use <stdbool.h> should be aware of some limitations
+ and standards compliance issues.
+
+ Standards compliance:
+
+ - <stdbool.h> must be #included before 'bool', 'false', 'true'
+ can be used.
+
+ - You cannot assume that sizeof (bool) == 1.
+
+ - Programs should not undefine the macros bool, true, and false,
+ as C99 lists that as an "obsolescent feature".
+
+ Limitations of this substitute, when used in a C89 environment:
+
+ - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+ - You cannot assume that _Bool is a typedef; it might be a macro.
+
+ - Bit-fields of type 'bool' are not supported. Portable code
+ should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+ - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+ performed in such a way that every nonzero value gets converted
+ to 'true', and zero gets converted to 'false'. This doesn't work
+ with this substitute. With this substitute, only the values 0 and 1
+ give the expected result when converted to _Bool' or 'bool'.
+
+ - C99 allows the use of (_Bool)0.0 in constant expressions, but
+ this substitute cannot always provide this property.
+
+ Also, it is suggested that programs use 'bool' rather than '_Bool';
+ this isn't required, but 'bool' is more common. */

+/* Set up the following warnings, based on which modules are in use.
+ GNU Coding Standards discourage the use of fseek, since it imposes
+ an arbitrary limitation on some 32-bit hosts. Remember that the
+ fseek module depends on the fseeko module, so we only have three
+ cases to consider:
+
+ 1. The developer is not using either module. Issue a warning under
+ GNULIB_POSIXCHECK for both functions, to remind them that both
+ functions have bugs on some systems. _GL_NO_LARGE_FILES has no
+ impact on this warning.
+
+ 2. The developer is using both modules. They may be unaware of the
+ arbitrary limitations of fseek, so issue a warning under
+ GNULIB_POSIXCHECK. On the other hand, they may be using both
+ modules intentionally, so the developer can define
+ _GL_NO_LARGE_FILES in the compilation units where the use of fseek
+ is safe, to silence the warning.
+
+ 3. The developer is using the fseeko module, but not fseek. Gnulib
+ guarantees that fseek will still work around platform bugs in that
+ case, but we presume that the developer is aware of the pitfalls of
+ fseek and was trying to avoid it, so issue a warning even when
+ GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
+ defined to silence the warning in particular compilation units.
+ In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
+ fseek gets defined as a macro, it is recommended that the developer
+ uses the fseek module, even if he is not calling the fseek function.
+
+ Most gnulib clients that perform stream operations should fall into

+ the four* bytes in the longword in question are equal to NUL or
+ c. We first use an xor with repeated_c. This reduces the task
+ to testing whether *any of the four* bytes in longword1 or
+ longword2 is zero.
+
+ Let's consider longword1. We compute tmp =
+ ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
+ That is, we perform the following operations:
+ 1. Subtract repeated_one.
+ 2. & ~longword1.
+ 3. & a mask consisting of 0x80 in every byte.
+ Consider what happens in each byte:
+ - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+ and step 3 transforms it into 0x80. A carry can also be propagated
+ to more significant bytes.
+ - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+ position k (0 <= k <= 7); so the lowest k bits are 0. After step 1,
+ the byte ends in a single bit of value 0 and k bits of value 1.
+ After step 2, the result is just k bits of value 1: 2^k - 1. After
+ step 3, the result is 0. And no carry is produced.
+ So, if longword1 has only non-zero bytes, tmp is zero.
+ Whereas if longword1 has a zero byte, call j the position of the least
+ significant zero byte. Then the result has a zero at positions 0, ...,
+ j-1 and a 0x80 at position j. We cannot predict the result at the more
+ significant bytes (positions j+1..3), but it does not matter since we
+ already have a non-zero bit at position 8*j+7.
+
+ The test whether any byte in longword1 or longword2 is zero is equivalent
+ to testing whether tmp1 is nonzero or tmp2 is nonzero. We can combine
+ this into a single test, whether (tmp1 | tmp2) is nonzero.
+
+ This test can read more than one byte beyond the end of a string,
+ depending on where the terminating NUL is encountered. However,
+ this is considered safe since the initialization phase ensured
+ that the read will be aligned, therefore, the read will not cross
+ page boundaries and will not cause a fault. */

+/* Each of these macros verifies that its argument R is nonzero. To
+ be portable, R should be an integer constant expression. Unlike
+ assert (R), there is no run-time overhead.
+
+ If _Static_assert works, verify (R) uses it directly. Similarly,
+ _GL_VERIFY_TRUE works by packaging a _Static_assert inside a struct
+ that is an operand of sizeof.
+
+ The code below uses several ideas for C++ compilers, and for C
+ compilers that do not support _Static_assert:
+
+ * The first step is ((R) ? 1 : -1). Given an expression R, of
+ integral or boolean or floating-point type, this yields an
+ expression of integral type, whose value is later verified to be
+ constant and nonnegative.
+
+ * Next this expression W is wrapped in a type
+ struct _gl_verify_type {
+ unsigned int _gl_verify_error_if_negative: W;
+ }.
+ If W is negative, this yields a compile-time error. No compiler can
+ deal with a bit-field of negative size.
+
+ One might think that an array size check would have the same
+ effect, that is, that the type struct { unsigned int dummy[W]; }
+ would work as well. However, inside a function, some compilers
+ (such as C++ compilers and GNU C) allow local parameters and
+ variables inside array size expressions. With these compilers,
+ an array size check would not properly diagnose this misuse of
+ the verify macro:
+
+ void function (int n) { verify (n < 0); }
+
+ * For the verify macro, the struct _gl_verify_type will need to
+ somehow be embedded into a declaration. To be portable, this
+ declaration must declare an object, a constant, a function, or a
+ typedef name. If the declared entity uses the type directly,
+ such as in
+
+ struct dummy {...};
+ typedef struct {...} dummy;
+ extern struct {...} *dummy;
+ extern void dummy (struct {...} *);
+ extern struct {...} *dummy (void);
+
+ two uses of the verify macro would yield colliding declarations
+ if the entity names are not disambiguated. A workaround is to
+ attach the current line number to the entity name:
+
+ #define _GL_CONCAT0(x, y) x##y
+ #define _GL_CONCAT(x, y) _GL_CONCAT0 (x, y)
+ extern struct {...} * _GL_CONCAT (dummy, __LINE__);
+
+ But this has the problem that two invocations of verify from
+ within the same macro would collide, since the __LINE__ value
+ would be the same for both invocations. (The GCC __COUNTER__
+ macro solves this problem, but is not portable.)
+
+ A solution is to use the sizeof operator. It yields a number,
+ getting rid of the identity of the type. Declarations like
+
+ extern int dummy [sizeof (struct {...})];
+ extern void dummy (int [sizeof (struct {...})]);
+ extern int (*dummy (void)) [sizeof (struct {...})];
+
+ can be repeated.
+
+ * Should the implementation use a named struct or an unnamed struct?
+ Which of the following alternatives can be used?
+
+ extern int dummy [sizeof (struct {...})];
+ extern int dummy [sizeof (struct _gl_verify_type {...})];
+ extern void dummy (int [sizeof (struct {...})]);
+ extern void dummy (int [sizeof (struct _gl_verify_type {...})]);
+ extern int (*dummy (void)) [sizeof (struct {...})];
+ extern int (*dummy (void)) [sizeof (struct _gl_verify_type {...})];
+
+ In the second and sixth case, the struct type is exported to the
+ outer scope; two such declarations therefore collide. GCC warns
+ about the first, third, and fourth cases. So the only remaining
+ possibility is the fifth case:
+
+ extern int (*dummy (void)) [sizeof (struct {...})];
+
+ * GCC warns about duplicate declarations of the dummy function if
+ -Wredundant_decls is used. GCC 4.3 and later have a builtin
+ __COUNTER__ macro that can let us generate unique identifiers for
+ each dummy function, to suppress this warning.
+
+ * This implementation exploits the fact that older versions of GCC,
+ which do not support _Static_assert, also do not warn about the
+ last declaration mentioned above.
+
+ * In C++, any struct definition inside sizeof is invalid.
+ Use a template type to work around the problem. */

+
+ This causes x2nrealloc to allocate a block of some nonzero size the
+ first time it is called.
+
+ To have finer-grained control over the initial size, set *PN to a
+ nonzero value before calling this function with P == NULL. For
+ example:
+
+ int *p = NULL;
+ size_t used = 0;
+ size_t allocated = 0;
+ size_t allocated1 = 1000;
+
+ void
+ append_int (int value)
+ {
+ if (used == allocated)
+ {

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl default (if it is not specified or empty) is 'no-libtool'.
+dnl INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl depending on --{enable,disable}-{shared,static} and on the presence of
+dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl implementations (in libc or libintl) without the ngettext() function
+dnl will be ignored. If NEEDSYMBOL is specified and is
+dnl 'need-formatstring-macros', then GNU gettext implementations that don't
+dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries. If empty,
+dnl the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl and used.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl Catalog format: none
+dnl Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+dnl Sets INCLUDE_NEXT and PRAGMA_SYSTEM_HEADER.
+dnl
+dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
+dnl 'include' otherwise.
+dnl
+dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
+dnl supports it in the special case that it is the first include directive in
+dnl the given file, or to 'include' otherwise.
+dnl
+dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
+dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
+dnl '#pragma GCC system_header' has the same effect as if the file was found
+dnl through the include search path specified with '-isystem' options (as
+dnl opposed to the search path specified with '-I' options). Namely, gcc
+dnl does not warn about some things, and on some systems (Solaris and Interix)
+dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
+dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
+dnl of plain '__STDC__'.
+dnl
+dnl PRAGMA_COLUMNS can be used in files that override system header files, so
+dnl as to avoid compilation errors on HP NonStop systems when the gnulib file
+dnl is included by a system header file that does a "#pragma COLUMNS 80" (which
+dnl has the effect of truncating the lines of that file and all files that it
+dnl includes to 80 columns) and the gnulib file has lines longer than 80

+# target-version format.
+#
+# source-version can be: support for
+# 1.3 inner classes
+# 1.4 assert keyword
+# 1.5 generic classes and methods
+# 1.6 (not yet supported)
+#
+# target-version can be: classfile version:

+# 1.2 46.0
+# 1.3 47.0
+# 1.4 48.0
+# 1.5 49.0
+# 1.6 50.0
+# The classfile version of a .class file can be determined through the "file"
+# command. More portably, the classfile major version can be determined through
+# "od -A n -t d1 -j 7 -N 1 classfile".
+# target-version can also be omitted. In this case, the required target-version
+# is determined from the found JVM (see macro gt_JAVAEXEC):
+# target-version for JVM
+# 1.1 JDK 1.1, jview
+# 1.2 JDK/JRE 1.2
+# 1.3 JDK/JRE 1.3, gij 3.3, 3.4
+# 1.4 JDK/JRE 1.4, gij 4.0, 4.1
+# 1.5 JDK/JRE 1.5
+# 1.6 JDK/JRE 1.6
+# Note: gij >= 3.3 can in some cases handle classes compiled with -target 1.4,
+# and gij >= 4.1 can in some cases partially handle classes compiled with
+# -target 1.5, but I have no idea how complete this support is.
+#
+# Specifying target-version is useful when building a library (.jar) that is
+# useful outside the given package. Omitting target-version is useful when
+# building an application.
+#
+# It is unreasonable to ask for:
+# - target-version < 1.4 with source-version >= 1.4, or
+# - target-version < 1.5 with source-version >= 1.5, or
+# - target-version < 1.6 with source-version >= 1.6,
+# because even Sun's javac doesn't support these combinations.
+#
+# It is redundant to ask for a target-version > source-version, since the
+# smaller target-version = source-version will also always work and newer JVMs
+# support the older target-versions too. Except for the case

+dnl 2) The posix_spawn_file_actions_addopen function does not support file

+dnl posix_spawn on AIX 5.3..6.1 has also a third bug: It does not work

+dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak

+# Parameters (shell variables):
+#
+# prohibit | require
+#
+# Regular expression (ERE) denoting either a forbidden construct
+# or a required construct. Those arguments are exclusive.
+#
+# exclude
+#
+# Regular expression (ERE) denoting lines to ignore that matched
+# a prohibit construct. For example, this can be used to exclude
+# comments that mention why the nearby code uses an alternative
+# construct instead of the simpler prohibited construct.
+#
+# in_vc_files | in_files
+#
+# grep-E-style regexp selecting the files to check. For in_vc_files,
+# the regexp is used to select matching files from the list of all
+# version-controlled files; for in_files, it's from the names printed
+# by "find $(srcdir)". When neither is specified, use all files that
+# are under version control.
+#
+# containing | non_containing
+#
+# Select the files (non) containing strings matching this regexp.
+# If both arguments are specified then CONTAINING takes
+# precedence.
+#
+# with_grep_options
+#
+# Extra options for grep.
+#
+# ignore_case
+#
+# Ignore case.
+#
+# halt
+#
+# Message to display before to halting execution.
+#
+# Finally, you may exempt files based on an ERE matching file names.
+# For example, to exempt from the sc_space_tab check all files with the
+# .diff suffix, set this Make variable:
+#
+# exclude_file_name_regexp--sc_space_tab = \.diff$

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'". For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK). If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this". You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <http://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'". For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK). If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this". You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'". For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK). If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this". You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <http://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'". For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK). If the

+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this". You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.

+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'". For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'". For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK). If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this". You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <http://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>
+#. and use glyphs suitable for your language.

+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'". For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK). If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this". You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.

+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'". For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK). If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this". You should always include translations

+#. for your locale.
+#.
+#. If you don't know what to put here, please see

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'". For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to

+#. TRANSLATORS:
+#. Get translations for open and closing quotation marks.
+#. The message catalog should translate "`" to a left
+#. quotation mark suitable for the locale, and similarly for
+#. "'". For example, a French Unicode local should translate
+#. these to U+00AB (LEFT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), and U+00BB (RIGHT-POINTING DOUBLE ANGLE
+#. QUOTATION MARK), respectively.
+#.
+#. If the catalog has no translation, we will try to
+#. use Unicode U+2018 (LEFT SINGLE QUOTATION MARK) and
+#. Unicode U+2019 (RIGHT SINGLE QUOTATION MARK). If the
+#. current locale is not Unicode, locale_quoting_style
+#. will quote 'like this', and clocale_quoting_style will
+#. quote "like this". You should always include translations
+#. for "`" and "'" even if U+2018 and U+2019 are appropriate
+#. for your locale.
+#.
+#. If you don't know what to put here, please see
+#. <http://en.wikipedia.org/wiki/Quotation_marks_in_other_languages>

+# define GRAM_H_
+
+/* Representation of the grammar rules:
+
+ NTOKENS is the number of tokens, and NVARS is the number of
+ variables (nonterminals). NSYMS is the total number, ntokens +
+ nvars.
+
+ Each symbol (either token or variable) receives a symbol number.
+ Numbers 0 to NTOKENS - 1 are for tokens, and NTOKENS to NSYMS - 1
+ are for variables. Symbol number zero is the end-of-input token.
+ This token is counted in ntokens. The true number of token values
+ assigned is NTOKENS reduced by one for each alias declaration.
+
+ The rules receive rule numbers 1 to NRULES in the order they are
+ written. More precisely Bison augments the grammar with the
+ initial rule, `$accept: START-SYMBOL $end', which is numbered 1,
+ all the user rules are 2, 3 etc. Each time a rule number is
+ presented to the user, we subtract 1, so *displayed* rule numbers
+ are 0, 1, 2...
+
+ Internally, we cannot use the number 0 for a rule because for
+ instance RITEM stores both symbol (the RHS) and rule numbers: the
+ symbols are shorts >= 0, and rule number are stored negative.
+ Therefore 0 cannot be used, since it would be both the rule number
+ 0, and the token $end).
+
+ Actions are accessed via the rule number.
+
+ The rules themselves are described by several arrays: amongst which
+ RITEM, and RULES.
+
+ RULES is an array of rules, whose members are:
+
+ RULES[R].lhs -- the symbol of the left hand side of rule R.
+
+ RULES[R].rhs -- the index in RITEM of the beginning of the portion
+ for rule R.
+
+ RULES[R].prec -- the symbol providing the precedence level of R.
+
+ RULES[R].precsym -- the symbol attached (via %prec) to give its
+ precedence to R. Of course, if set, it is equal to `prec', but we
+ need to distinguish one from the other when reducing: a symbol used
+ in a %prec is not useless.
+
+ RULES[R].assoc -- the associativity of R.
+
+ RULES[R].dprec -- the dynamic precedence level of R (for GLR
+ parsing).
+
+ RULES[R].merger -- index of merging function for R (for GLR
+ parsing).
+
+ RULES[R].line -- the line where R was defined.
+
+ RULES[R].useful -- true iff the rule is used (i.e., false if thrown
+ away by reduce).
+
+ The right hand side is stored as symbol numbers in a portion of
+ RITEM.
+
+ The length of the portion is one greater than the number of symbols
+ in the rule's right hand side. The last element in the portion
+ contains minus R, which identifies it as the end of a portion and
+ says which rule it is for.
+
+ The portions of RITEM come in order of increasing rule number.
+ NRITEMS is the total length of RITEM. Each element of RITEM is
+ called an "item" and its index in RITEM is an item number.
+
+ Item numbers are used in the finite state machine to represent
+ places that parsing can get to.
+
+ SYMBOLS[I]->prec records the precedence level of each symbol.
+
+ Precedence levels are assigned in increasing order starting with 1
+ so that numerically higher precedence values mean tighter binding
+ as they ought to. Zero as a symbol or rule's precedence means none
+ is assigned.
+
+ Associativities are recorded similarly in SYMBOLS[I]->assoc. */

+ their default reductions have been disabled). Iff there is a
+ lookahead token, it should also be invoked before reporting a syntax
+ error. This latter case is for the sake of the debugging output.
+
+ For parse.lac=full, the implementation of YY_LAC_ESTABLISH is as

+
+/* These type definitions are used to represent a nondeterministic
+ finite state machine that parses the specified grammar. This
+ information is generated by the function generate_states in the
+ file LR0.
+
+ Each state of the machine is described by a set of items --
+ particular positions in particular rules -- that are the possible
+ places where parsing could continue when the machine is in this
+ state. These symbols at these items are the allowable inputs that
+ can follow now.
+
+ A core represents one state. States are numbered in the NUMBER
+ field. When generate_states is finished, the starting state is
+ state 0 and NSTATES is the number of states. (FIXME: This sentence
+ is no longer true: A transition to a state whose state number is
+ NSTATES indicates termination.) All the cores are chained together
+ and FIRST_STATE points to the first one (state 0).
+
+ For each state there is a particular symbol which must have been
+ the last thing accepted to reach that state. It is the
+ ACCESSING_SYMBOL of the core.
+
+ Each core contains a vector of NITEMS items which are the indices
+ in the RITEM vector of the items that are selected in this state.
+
+ The two types of actions are shifts/gotos (push the lookahead token
+ and read another/goto to the state designated by a nterm) and
+ reductions (combine the last n things on the stack via a rule,
+ replace them with the symbol that the rule derives, and leave the
+ lookahead token alone). When the states are generated, these
+ actions are represented in two other lists.
+
+ Each transition structure describes the possible transitions out
+ of one state, the state whose number is in the number field. Each
+ contains a vector of numbers of the states that transitions can go
+ to. The accessing_symbol fields of those states' cores say what
+ kind of input leads to them.
+
+ A transition to state zero should be ignored: conflict resolution
+ deletes transitions by having them point to zero.
+
+ Each reductions structure describes the possible reductions at the
+ state whose number is in the number field. rules is an array of
+ num rules. lookahead_tokens is an array of bitsets, one per rule.
+
+ Conflict resolution can decide that certain tokens in certain
+ states should explicitly be errors (for implementing %nonassoc).
+ For each state, the tokens that are errors for this reason are
+ recorded in an errs structure, which holds the token numbers.
+
+ There is at least one goto transition present in state zero. It
+ leads to a next-to-final state whose accessing_symbol is the
+ grammar's start symbol. The next-to-final state has one shift to
+ the final state, whose accessing_symbol is zero (end of input).
+ The final state has one shift, which goes to the termination state.
+ The reason for the extra state at the end is to placate the
+ parser's strategy of making all decisions one token ahead of its
+ actions. */

+/* The parser tables consist of these tables.
+
+ YYTRANSLATE = vector mapping yylex's token numbers into bison's
+ token numbers.
+
+ YYTNAME = vector of string-names indexed by bison token number.
+
+ YYTOKNUM = vector of yylex token numbers corresponding to entries
+ in YYTNAME.
+
+ YYRLINE = vector of line-numbers of all rules. For yydebug
+ printouts.
+
+ YYRHS = vector of items of all rules. This is exactly what RITEMS
+ contains. For yydebug and for semantic parser.
+
+ YYPRHS[R] = index in YYRHS of first item for rule R.
+
+ YYR1[R] = symbol number of symbol that rule R derives.
+
+ YYR2[R] = number of symbols composing right hand side of rule R.
+
+ YYSTOS[S] = the symbol number of the symbol that leads to state S.
+
+ YYFINAL = the state number of the termination state.
+
+ YYTABLE = a vector filled with portions for different uses, found
+ via YYPACT and YYPGOTO, described below.
+
+ YYLAST ( = high) the number of the last element of YYTABLE, i.e.,
+ sizeof (YYTABLE) - 1.
+
+ YYCHECK = a vector indexed in parallel with YYTABLE. It indicates,
+ in a roundabout way, the bounds of the portion you are trying to
+ examine.
+
+ Suppose that the portion of YYTABLE starts at index P and the index
+ to be examined within the portion is I. Then if YYCHECK[P+I] != I,
+ I is outside the bounds of what is actually allocated, and the
+ default (from YYDEFACT or YYDEFGOTO) should be used. Otherwise,
+ YYTABLE[P+I] should be used.
+
+ YYDEFACT[S] = default reduction number in state s. Performed when
+ YYTABLE doesn't specify something else to do. Zero means the default
+ is an error.
+
+ YYDEFGOTO[I] = default state to go to after a reduction of a rule
+ that generates variable NTOKENS + I, except when YYTABLE specifies
+ something else to do.
+
+ YYPACT[S] = index in YYTABLE of the portion describing state S.
+ The lookahead token's number, I, is used to index that portion of
+ YYTABLE to find out what action to perform.
+
+ If YYPACT[S] == YYPACT_NINF, if YYPACT[S] + I is outside the bounds
+ of YYTABLE (from 0 to YYLAST), or I is outside the bounds for portion
+ S (that is, YYCHECK[YYPACT[S] + I] != I), then the default action
+ (that is, YYDEFACT[S]) should be used instead of YYTABLE. Otherwise,
+ the value YYTABLE[YYPACT[S] + I] should be used even if
+ YYPACT[S] < 0.
+
+ If the value in YYTABLE is positive, we shift the token and go to
+ that state.
+
+ If the value is negative, it is minus a rule number to reduce by.
+
+ If the value is YYTABLE_NINF, it's a syntax error.
+
+ YYPGOTO[I] = the index in YYTABLE of the portion describing what to
+ do after reducing a rule that derives variable I + NTOKENS. This
+ portion is indexed by the parser state number, S, as of before the
+ text for this nonterminal was read.
+
+ If YYPGOTO[I] + S is outside the bounds of YYTABLE (from 0 to YYLAST)
+ or if S is outside the bounds of the portion for I (that is,
+ YYCHECK[YYPGOTO[I] + S] != S), then the default state (that is,
+ YYDEFGOTO[I]) should be used instead of YYTABLE. Otherwise,
+ YYTABLE[YYPGOTO[I] + S] is the state to go to even if YYPGOTO[I] < 0.
+
+ When the above YYPACT, YYPGOTO, and YYCHECK tests determine that a
+ value from YYTABLE should be used, that value is never zero, so it is
+ useless to check for zero. When those tests indicate that the value
+ from YYDEFACT or YYDEFGOTO should be used instead, the value from
+ YYTABLE *might* be zero, which, as a consequence of the way in which
+ the tables are constructed, also happens to indicate that YYDEFACT or
+ YYDEFGOTO should be used. However, the YYTABLE value cannot be
+ trusted when the YYDEFACT or YYDEFGOTO value should be used. In
+ summary, forget about zero values in YYTABLE.

+dnl For example, in AWK:
+dnl
+dnl getline $!4*0;
+dnl
+dnl The grammar below (from GNU AWK 3.1.0) using canonical LR(1) or IELR(1)
+dnl parses it as:
+dnl
+dnl getline $!(4*0);
+dnl
+dnl That is, they shift `*' immediately and make it part of the getline
+dnl argument.
+dnl
+dnl The grammar below using LALR(1) parses it as a syntax error. So does
+dnl GNU AWK 3.0.6, 3.1.0, and 3.1.1. They reduce the full getline expression
+dnl before shifting `*' even though `*' is not a valid lookahead.
+dnl
+dnl GNU AWK 3.1.2, 3.1.3, 3.1.4, and 3.1.5 parse it as:
+dnl
+dnl (getline $!4)*0;
+dnl
+dnl That is, like the other versions of GNU AWK, they reduce the full getline
+dnl expression before shifting `*'. However, because of a different LHS on the
+dnl getline rule, `*' actually is a valid lookahead. Solaris /usr/xpg4/bin/awk
+dnl and the Open Group awk specification seem to agree:
+dnl
+dnl http://www.opengroup.org/pubs/online/7908799/xcu/awk.html
+dnl
+dnl /bin/nawk and /bin/awk on Solaris 10 report it as a syntax error, but they
+dnl don't like even `print $!4;'.

+#
+# If TEST-SPEC contains the attribute no-xml, then invoke bison using

+# Otherwise, check that everything in the `.output' file starting with
+# the definition of state 0 is the same as the entire value of
+# TABLES-OR-LAST-STATE.
+#
+# Expand the M4 in OTHER-CHECKS to perform additional checks of the
+# `.output' file, which is named `input.output', and/or grammar file,
+# which is named `input.y'.

+
+ State 13 has a R/R conflict that cannot be predicted by Bison's LR(1)
+ algorithm using annotations alone. That is, when state 11's successor on
+ 'd' is merged with state 5 (which is originally just state 1's successor on
+ 'd'), state 5's successor on 'e' must then be changed because the resulting

+ This grammar is designed carefully to make sure that, despite Bison's LR(1)

+ Otherwise (for example, if you remove the first 'c' in each of rules 6 and
+ 7), state 5's successor on 'e' would never be merged with state 8's, so the

+ algorithm using annotations alone. That is, when state 11's successor on
+ 'd' is merged with state 5 (which is originally just state 1's successor on
+ 'd'), state 5's successor on 'e' must then be changed because the resulting

+ Otherwise (for example, if you remove the first 'c' in each of rules 6 and
