This file is offered as-is, +without warranty of any kind. + +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 `' 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 bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /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. + diff --git a/LICENSE b/LICENSE new file mode 100644 index 0000000..c9b44cb --- /dev/null +++ b/LICENSE @@ -0,0 +1,18 @@ +Permission is hereby granted, free of charge, to any person obtaining +a copy of this software and associated documentation files (the +"Software"), to deal in the Software without restriction, including +without limitation the rights to use, copy, modify, merge, publish, +distribute, sublicense, and/or sell copies of the Software, and to +permit persons to whom the Software is furnished to do so, subject to +the following conditions: + +The above copyright notice and this permission notice shall be +included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, +EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND +NONINFRINGEMENT.

Once we have such counters, + we can use them in libunwind to implement an efficient version of a + cache-validation routine. + Once this has been fixed, update the libunwind man page accordingly. + Effectively, what this means is that unw_flush_cache() doesn't have + to be called by applications except for extraordinary circumstances + (e.g., if application implements its own runtime loader). ++ man-page for unw_is_fpreg() ++ man-page for _U_dyn_cancel() ++ man-page for _U_dyn_register() ++ global data is not protected by a lock; causes problems if two threads + call ia64_init() at almost the same time ++ cache the value of *cfm_loc; each rotate_FOO() call needs it! ++ implement the remote-lookup of the dynamic registration list ++ when doing sigreturn, must restore fp regs (and perhaps other regs) the same + way as the (user-level) gate.S sigreturn path does! ++ unw_resume() must at least restore gp (r1)! consider restoring all + scratch regs (but what's the performance impact on exception handling?); + alternative: restore scratch regs that may be used during procedure + call/return (e.g., r8-r11, f8-f11) ++ implement unw_resume() for the case where the current register frame is split + across multiple backing stores ++ document restricions on using unw_resume(): ++ implement remote cases of unw_resume() ++ test both with UNW_LOCAL_ONLY and without where this makes sense ++ allow region-length (insn_count) in unw_dyn_region_info_t to be negative + to indicate counting from the end of the procedure (to make it possible + for differently-sized procedures to share the same region list if they + share the same prologue/epilogue). ++ it appears that it is currently not possible to read register UNW_IA64_TP; + fix that => no, attempts to access r13 will result in access_reg() callbacks, + as desired; for local-case, access to r13 will fail though (since + getcontext() doesn't, and shouldn't, capture r13) ++ document the special nature of UNW_IA64_GP: read-only, but adjusted + automatically if the IP is changed ++ use pthread-mutexes where necessary, atomic ops where possible ++ man-page for unw_init_local() ++ man-page for unw_init_remote() ++ man-page for unw_create_addr_space() ++ man-page for unw_destroy_addr_space() ++ man-page for unw_get_proc_info() ++ man-page for unw_get_proc_name() ++ man-page for unw_get_accessors() ++ man-page for unw_regname() ++ man-page for unw_flush_cache() ++ man-page for unw_set_caching_policy() ++ man-page for unw_getcontext() ++ man-page for unw_is_signal_frame() ++ man-page for unw_step() ++ man-page for unw_get_reg() ++ man-page for unw_set_reg() ++ man-page for unw_get_fpreg() ++ man-page for unw_set_fpreg() ++ test with Intel compiler diff --git a/acinclude.m4 b/acinclude.m4 new file mode 100644 index 0000000..497f7c2 --- /dev/null +++ b/acinclude.m4 @@ -0,0 +1,32 @@ +AC_DEFUN([LIBUNWIND___THREAD], +[dnl Check whether the compiler supports the __thread keyword. +if test "x$enable___thread" != xno; then + AC_CACHE_CHECK([for __thread], libc_cv_gcc___thread, + [cat > conftest.c <<\EOF + __thread int a = 42; +EOF + if AC_TRY_COMMAND([${CC-cc} $CFLAGS -c conftest.c >&AS_MESSAGE_LOG_FD]); then + libc_cv_gcc___thread=yes + else + libc_cv_gcc___thread=no + fi + rm -f conftest*]) + if test "$libc_cv_gcc___thread" = yes; then + AC_DEFINE(HAVE___THREAD, 1, + [Define to 1 if __thread keyword is supported by the C compiler.]) + fi +else + libc_cv_gcc___thread=no +fi]) + +AC_DEFUN([CHECK_ATOMIC_OPS], +[dnl Check whether the system has the atomic_ops package installed. + AC_CHECK_HEADERS(atomic_ops.h) +# +# Don't link against libatomic_ops for now.

In the local case, the initial machine +state is captured by an unwind context (currently the same as +ucontext_t). In the remote case, the initial machine state is +captured by an unwind accessor structure, which provides callback +routines for reading/writing memory and registers and for obtaining +unwind information. + +Once a cursor has been initialized, you can step through the call +chain with the unw_step() routine. The frame registers and the +preserved state can then be accessed with unw_get_reg() or modified +with unw_set_reg(). For floating-point registers, there are separate +unw_get_fpreg() and unw_set_fpreg() routines (on some arches, e.g., +Alpha, these could be just aliases for unw_{g,s}et_reg()). The +unw_resume() routine can be used to resume execution at an arbitrary +point in the call-chain (as identified by an unwind cursor).

The frame state +describes the subset of the machine\-state that consists of the +\fIframe registers\fP +(typically the instruction\-pointer and the +stack\-pointer) and all callee\-saved registers (preserved registers). +The frame state describes each register either by providing its +current value (for frame registers) or by providing the location at +which the current value is stored (callee\-saved registers). +.PP +For statically generated code, the compiler normally takes care of +emitting \fIunwind\-info\fP +which provides the minimum amount of +information needed to reconstruct the frame\-state for each instruction +in a procedure. For dynamically generated code, the runtime code +generator must use the dynamic unwind\-info interface provided by +libunwind +to supply the equivalent information. This manual +page describes the format of this information in detail. +.PP +For the purpose of this discussion, a \fIprocedure\fP +is defined to +be an arbitrary piece of \fIcontiguous\fP +code. Normally, each +procedure directly corresponds to a function in the source\-language +but this is not strictly required. For example, a runtime +code\-generator could translate a given function into two separate +(discontiguous) procedures: one for frequently\-executed (hot) code and +one for rarely\-executed (cold) code. Similarly, simple +source\-language functions (usually leaf functions) may get translated +into code for which the default unwind\-conventions apply and for such +code, it is not strictly necessary to register dynamic unwind\-info. +.PP +A procedure logically consists of a sequence of \fIregions\fP\&. +Regions are nested in the sense that the frame state at the end of one +region is, by default, assumed to be the frame state for the next +region. Each region is thought of as being divided into a +\fIprologue\fP, +a \fIbody\fP, +and an \fIepilogue\fP\&. +Each of them +can be empty. If non\-empty, the prologue sets up the frame state for +the body. For example, the prologue may need to allocate some space +on the stack and save certain callee\-saved registers. The body +performs the actual work of the procedure but does not change the +frame state in any way. If non\-empty, the epilogue restores the +previous frame state and as such it undoes or cancels the effect of +the prologue. In fact, a single epilogue may undo the effect of the +prologues of several (nested) regions. +.PP +We should point out that even though the prologue, body, and epilogue +are logically separate entities, optimizing code\-generators will +generally interleave instructions from all three entities. For this +reason, the dynamic unwind\-info interface of libunwind +makes no +distinction whatsoever between prologue and body. Similarly, the +exact set of instructions that make up an epilogue is also irrelevant. +The only point in the epilogue that needs to be described explicitly +by the dynamic unwind\-info is the point at which the stack\-pointer +gets restored. The reason this point needs to be described is that +once the stack\-pointer is restored, all values saved in the +deallocated portion of the stack frame become invalid and hence +libunwind +needs to know about it. The portion of the frame +state not saved on the stack is assume to remain valid through the end +of the region. For this reason, there is usually no need to describe +instructions which restore the contents of callee\-saved registers. +.PP +Within a region, each instruction that affects the frame state in some +fashion needs to be described with an operation descriptor. For this +purpose, each instruction in the region is assigned a unique index. +Exactly how this index is derived depends on the architecture. For +example, on RISC and EPIC\-style architecture, instructions have a +fixed size so it\&'s possible to simply number the instructions. In +contrast, most CISC use variable\-length instruction encodings, so it +is usually necessary to use a byte\-offset as the index. Given the +instruction index, the operation descriptor specifies the effect of +the instruction in an abstract manner. For example, it might express +that the instruction stores calle\-saved register r1 +at offset 16 +in the stack frame. +.PP +.SH PROCEDURES + +.PP +A runtime code\-generator registers the dynamic unwind\-info of a +procedure by setting up a structure of type unw_dyn_info_t +and calling _U_dyn_register(), +passing the address of the +structure as the sole argument. The members of the +unw_dyn_info_t +structure are described below: +.TP +void *next + Private to libunwind\&. +Must not be used +by the application. +.TP +void *prev + Private to libunwind\&. +Must not be used +by the application. +.TP +unw_word_t start_ip + The start\-address of the +instructions of the procedure (remember: procedure are defined to be +contiguous pieces of code, so a single code\-range is sufficient). +.TP +unw_word_t end_ip + The end\-address of the +instructions of the procedure (non\-inclusive, that is, +end_ip\-start_ip +is the size of the procedure in +bytes). +.TP +unw_word_t gp + The global\-pointer value in use +for this procedure. The exact meaing of the global\-pointer is +architecture\-specific and on some architecture, it is not used at +all. +.TP +int32_t format + The format of the unwind\-info. +This member can be one of UNW_INFO_FORMAT_DYNAMIC, +UNW_INFO_FORMAT_TABLE, +or +UNW_INFO_FORMAT_REMOTE_TABLE\&. +.TP +union u + This union contains one sub\-member +structure for every possible unwind\-info format: +.RS +.TP +unw_dyn_proc_info_t pi + This member is used +for format UNW_INFO_FORMAT_DYNAMIC\&. +.TP +unw_dyn_table_info_t ti + This member is used +for format UNW_INFO_FORMAT_TABLE\&. +.TP +unw_dyn_remote_table_info_t rti + This member +is used for format UNW_INFO_FORMAT_REMOTE_TABLE\&. +.RE +.RS +.PP +The format of these sub\-members is described in detail below. +.RE +.PP +.SS PROC\-INFO FORMAT +.PP +This is the preferred dynamic unwind\-info format and it is generally +the one used by full\-blown runtime code\-generators. In this format, +the details of a procedure are described by a structure of type +unw_dyn_proc_info_t\&. +This structure contains the following +members: +.PP +.RE +.TP +unw_word_t name_ptr + The address of a +(human\-readable) name of the procedure or 0 if no such name is +available. If non\-zero, The string stored at this address must be +ASCII NUL terminated. For source languages that use name\-mangling +(such as C++ or Java) the string stored at this address should be +the \fIdemangled\fP +version of the name. +.PP +.TP +unw_word_t handler + The address of the +personality\-routine for this procedure. Personality\-routines are +used in conjunction with exception handling. See the C++ ABI draft +(http://www.codesourcery.com/cxx\-abi/) for an overview and a +description of the personality routine. If the procedure has no +personality routine, handler +must be set to 0. +.PP +.TP +uint32_t flags + A bitmask of flags. At the +moment, no flags have been defined and this member must be +set to 0. +.PP +.TP +unw_dyn_region_info_t *regions + A NULL\-terminated +linked list of region\-descriptors. See section ``Region +descriptors\&'' below for more details. +.PP +.SS TABLE\-INFO FORMAT +.PP +This format is generally used when the dynamically generated code was +derived from static code and the unwind\-info for the dynamic and the +static versions is identical. For example, this format can be useful +when loading statically\-generated code into an address\-space in a +non\-standard fashion (i.e., through some means other than +dlopen()). +In this format, the details of a group of procedures +is described by a structure of type unw_dyn_table_info\&. +This structure contains the following members: +.PP +.TP +unw_word_t name_ptr + The address of a +(human\-readable) name of the procedure or 0 if no such name is +available. If non\-zero, The string stored at this address must be +ASCII NUL terminated. For source languages that use name\-mangling +(such as C++ or Java) the string stored at this address should be +the \fIdemangled\fP +version of the name. +.PP +.TP +unw_word_t segbase + The segment\-base value +that needs to be added to the segment\-relative values stored in the +unwind\-info. The exact meaning of this value is +architecture\-specific. +.PP +.TP +unw_word_t table_len + The length of the +unwind\-info (table_data) +counted in units of words +(unw_word_t). +.PP +.TP +unw_word_t table_data + A pointer to the actual +data encoding the unwind\-info. The exact format is +architecture\-specific (see architecture\-specific sections below). +.PP +.SS REMOTE TABLE\-INFO FORMAT +.PP +The remote table\-info format has the same basic purpose as the regular +table\-info format. The only difference is that when libunwind +uses the unwind\-info, it will keep the table data in the target +address\-space (which may be remote). Consequently, the type of the +table_data +member is unw_word_t +rather than a pointer. +This implies that libunwind +will have to access the table\-data +via the address\-space\&'s access_mem() +call\-back, rather than +through a direct memory reference. +.PP +From the point of view of a runtime\-code generator, the remote +table\-info format offers no advantage and it is expected that such +generators will describe their procedures either with the proc\-info +format or the normal table\-info format. The main reason that the +remote table\-info format exists is to enable the +address\-space\-specific find_proc_info() +callback (see +unw_create_addr_space(3)) +to return unwind tables whose +data remains in remote memory. This can speed up unwinding (e.g., for +a debugger) because it reduces the amount of data that needs to be +loaded from remote memory. +.PP +.SH REGIONS DESCRIPTORS + +.PP +A region descriptor is a variable length structure that describes how +each instruction in the region affects the frame state. Of course, +most instructions in a region usualy do not change the frame state and +for those, nothing needs to be recorded in the region descriptor. A +region descriptor is a structure of type +unw_dyn_region_info_t +and has the following members: +.TP +unw_dyn_region_info_t *next + A pointer to the +next region. If this is the last region, next +is NULL\&. +.TP +int32_t insn_count + The length of the region in +instructions. Each instruction is assumed to have a fixed size (see +architecture\-specific sections for details). The value of +insn_count +may be negative in the last region of a procedure +(i.e., it may be negative only if next +is NULL). +A +negative value indicates that the region covers the last \fIN\fP +instructions of the procedure, where \fIN\fP +is the absolute value +of insn_count\&. +.TP +uint32_t op_count + The (allocated) length of +the op_count +array. +.TP +unw_dyn_op_t op + An array of dynamic unwind +directives. See Section ``Dynamic unwind directives\&'' for a +description of the directives. +.PP +A region descriptor with an insn_count +of zero is an +\fIempty region\fP +and such regions are perfectly legal. In fact, +empty regions can be useful to establish a particular frame state +before the start of another region. +.PP +A single region list can be shared across multiple procedures provided +those procedures share a common prologue and epilogue (their bodies +may differ, of course). Normally, such procedures consist of a canned +prologue, the body, and a canned epilogue. This could be described by +two regions: one covering the prologue and one covering the epilogue. +Since the body length is variable, the latter region would need to +specify a negative value in insn_count +such that +libunwind +knows that the region covers the end of the procedure +(up to the address specified by end_ip). +.PP +The region descriptor is a variable length structure to make it +possible to allocate all the necessary memory with a single +memory\-allocation request. To facilitate the allocation of a region +descriptors libunwind +provides a helper routine with the +following synopsis: +.PP +size_t +_U_dyn_region_size(int +op_count); +.PP +This routine returns the number of bytes needed to hold a region +descriptor with space for op_count +unwind directives. Note +that the length of the op +array does not have to match exactly +with the number of directives in a region. Instead, it is sufficient +if the op +array contains at least as many entries as there are +directives, since the end of the directives can always be indicated +with the UNW_DYN_STOP +directive. +.PP +.SH DYNAMIC UNWIND DIRECTIVES + +.PP +A dynamic unwind directive describes how the frame state changes +at a particular point within a region. The description is in +the form of a structure of type unw_dyn_op_t\&. +This +structure has the following members: +.TP +int8_t tag + The operation tag. Must be one +of the unw_dyn_operation_t +values described below. +.TP +int8_t qp + The qualifying predicate that controls +whether or not this directive is active. This is useful for +predicated architecturs such as IA\-64 or ARM, where the contents of +another (callee\-saved) register determines whether or not an +instruction is executed (takes effect). If the directive is always +active, this member should be set to the manifest constant +_U_QP_TRUE +(this constant is defined for all +architectures, predicated or not). +.TP +int16_t reg + The number of the register affected +by the instruction. +.TP +int32_t when + The region\-relative number of +the instruction to which this directive applies. For example, +a value of 0 means that the effect described by this directive +has taken place once the first instruction in the region has +executed. +.TP +unw_word_t val + The value to be applied by the +operation tag. The exact meaning of this value varies by tag. See +Section ``Operation tags\&'' below. +.PP +It is perfectly legitimate to specify multiple dynamic unwind +directives with the same when +value, if a particular instruction +has a complex effect on the frame state. +.PP +Empty regions by definition contain no actual instructions and as such +the directives are not tied to a particular instruction. By +convention, the when +member should be set to 0, however. +.PP +There is no need for the dynamic unwind directives to appear +in order of increasing when +values. If the directives happen to +be sorted in that order, it may result in slightly faster execution, +but a runtime code\-generator should not go to extra lengths just to +ensure that the directives are sorted. +.PP +IMPLEMENTATION NOTE: should libunwind +implementations for +certain architectures prefer the list of unwind directives to be +sorted, it is recommended that such implementations first check +whether the list happens to be sorted already and, if not, sort the +directives explicitly before the first use. With this approach, the +overhead of explicit sorting is only paid when there is a real benefit +and if the runtime code\-generator happens to generated sorted lists +naturally, the performance penalty is limited to a simple O(N) check. +.PP +.SS OPERATIONS TAGS +.PP +The possible operation tags are defined by enumeration type +unw_dyn_operation_t +which defines the following +values: +.PP +.TP +UNW_DYN_STOP + Marks the end of the dynamic unwind +directive list.

The frame state +describes the subset of the machine-state that consists of the +\emph{frame registers} (typically the instruction-pointer and the +stack-pointer) and all callee-saved registers (preserved registers). +The frame state describes each register either by providing its +current value (for frame registers) or by providing the location at +which the current value is stored (callee-saved registers). + +For statically generated code, the compiler normally takes care of +emitting \emph{unwind-info} which provides the minimum amount of +information needed to reconstruct the frame-state for each instruction +in a procedure. For dynamically generated code, the runtime code +generator must use the dynamic unwind-info interface provided by +\Prog{libunwind} to supply the equivalent information. This manual +page describes the format of this information in detail. + +For the purpose of this discussion, a \emph{procedure} is defined to +be an arbitrary piece of \emph{contiguous} code. Normally, each +procedure directly corresponds to a function in the source-language +but this is not strictly required. For example, a runtime +code-generator could translate a given function into two separate +(discontiguous) procedures: one for frequently-executed (hot) code and +one for rarely-executed (cold) code. Similarly, simple +source-language functions (usually leaf functions) may get translated +into code for which the default unwind-conventions apply and for such +code, it is not strictly necessary to register dynamic unwind-info. + +A procedure logically consists of a sequence of \emph{regions}. +Regions are nested in the sense that the frame state at the end of one +region is, by default, assumed to be the frame state for the next +region. Each region is thought of as being divided into a +\emph{prologue}, a \emph{body}, and an \emph{epilogue}. Each of them +can be empty. If non-empty, the prologue sets up the frame state for +the body. For example, the prologue may need to allocate some space +on the stack and save certain callee-saved registers. The body +performs the actual work of the procedure but does not change the +frame state in any way. If non-empty, the epilogue restores the +previous frame state and as such it undoes or cancels the effect of +the prologue. In fact, a single epilogue may undo the effect of the +prologues of several (nested) regions. + +We should point out that even though the prologue, body, and epilogue +are logically separate entities, optimizing code-generators will +generally interleave instructions from all three entities. For this +reason, the dynamic unwind-info interface of \Prog{libunwind} makes no +distinction whatsoever between prologue and body. Similarly, the +exact set of instructions that make up an epilogue is also irrelevant. +The only point in the epilogue that needs to be described explicitly +by the dynamic unwind-info is the point at which the stack-pointer +gets restored. The reason this point needs to be described is that +once the stack-pointer is restored, all values saved in the +deallocated portion of the stack frame become invalid and hence +\Prog{libunwind} needs to know about it. The portion of the frame +state not saved on the stack is assume to remain valid through the end +of the region. For this reason, there is usually no need to describe +instructions which restore the contents of callee-saved registers. + +Within a region, each instruction that affects the frame state in some +fashion needs to be described with an operation descriptor. For this +purpose, each instruction in the region is assigned a unique index. +Exactly how this index is derived depends on the architecture. For +example, on RISC and EPIC-style architecture, instructions have a +fixed size so it's possible to simply number the instructions. In +contrast, most CISC use variable-length instruction encodings, so it +is usually necessary to use a byte-offset as the index. Given the +instruction index, the operation descriptor specifies the effect of +the instruction in an abstract manner. For example, it might express +that the instruction stores calle-saved register \Var{r1} at offset 16 +in the stack frame. + +\section{Procedures} + +A runtime code-generator registers the dynamic unwind-info of a +procedure by setting up a structure of type \Type{unw\_dyn\_info\_t} +and calling \Func{\_U\_dyn\_register}(), passing the address of the +structure as the sole argument. The members of the +\Type{unw\_dyn\_info\_t} structure are described below: +\begin{itemize} +\item[\Type{void~*}next] Private to \Prog{libunwind}. Must not be used + by the application. +\item[\Type{void~*}prev] Private to \Prog{libunwind}. Must not be used + by the application. +\item[\Type{unw\_word\_t} \Var{start\_ip}] The start-address of the + instructions of the procedure (remember: procedure are defined to be + contiguous pieces of code, so a single code-range is sufficient). +\item[\Type{unw\_word\_t} \Var{end\_ip}] The end-address of the + instructions of the procedure (non-inclusive, that is, + \Var{end\_ip}-\Var{start\_ip} is the size of the procedure in + bytes). +\item[\Type{unw\_word\_t} \Var{gp}] The global-pointer value in use + for this procedure. The exact meaing of the global-pointer is + architecture-specific and on some architecture, it is not used at + all. +\item[\Type{int32\_t} \Var{format}] The format of the unwind-info. + This member can be one of \Const{UNW\_INFO\_FORMAT\_DYNAMIC}, + \Const{UNW\_INFO\_FORMAT\_TABLE}, or + \Const{UNW\_INFO\_FORMAT\_REMOTE\_TABLE}. +\item[\Type{union} \Var{u}] This union contains one sub-member + structure for every possible unwind-info format: + \begin{description} + \item[\Type{unw\_dyn\_proc\_info\_t} \Var{pi}] This member is used + for format \Const{UNW\_INFO\_FORMAT\_DYNAMIC}. + \item[\Type{unw\_dyn\_table\_info\_t} \Var{ti}] This member is used + for format \Const{UNW\_INFO\_FORMAT\_TABLE}. + \item[\Type{unw\_dyn\_remote\_table\_info\_t} \Var{rti}] This member + is used for format \Const{UNW\_INFO\_FORMAT\_REMOTE\_TABLE}. + \end{description}\ + The format of these sub-members is described in detail below. +\end{itemize} + +\subsection{Proc-info format} + +This is the preferred dynamic unwind-info format and it is generally +the one used by full-blown runtime code-generators. In this format, +the details of a procedure are described by a structure of type +\Type{unw\_dyn\_proc\_info\_t}. This structure contains the following +members: +\begin{description} + +\item[\Type{unw\_word\_t} \Var{name\_ptr}] The address of a + (human-readable) name of the procedure or 0 if no such name is + available. If non-zero, The string stored at this address must be + ASCII NUL terminated. For source languages that use name-mangling + (such as C++ or Java) the string stored at this address should be + the \emph{demangled} version of the name. + +\item[\Type{unw\_word\_t} \Var{handler}] The address of the + personality-routine for this procedure. Personality-routines are + used in conjunction with exception handling. See the C++ ABI draft + (http://www.codesourcery.com/cxx-abi/) for an overview and a + description of the personality routine. If the procedure has no + personality routine, \Var{handler} must be set to 0. + +\item[\Type{uint32\_t} \Var{flags}] A bitmask of flags. At the + moment, no flags have been defined and this member must be + set to 0. + +\item[\Type{unw\_dyn\_region\_info\_t~*}\Var{regions}] A NULL-terminated + linked list of region-descriptors. See section ``Region + descriptors'' below for more details. + +\end{description} + +\subsection{Table-info format} + +This format is generally used when the dynamically generated code was +derived from static code and the unwind-info for the dynamic and the +static versions is identical. For example, this format can be useful +when loading statically-generated code into an address-space in a +non-standard fashion (i.e., through some means other than +\Func{dlopen}()). In this format, the details of a group of procedures +is described by a structure of type \Type{unw\_dyn\_table\_info}. +This structure contains the following members: +\begin{description} + +\item[\Type{unw\_word\_t} \Var{name\_ptr}] The address of a + (human-readable) name of the procedure or 0 if no such name is + available. If non-zero, The string stored at this address must be + ASCII NUL terminated. For source languages that use name-mangling + (such as C++ or Java) the string stored at this address should be + the \emph{demangled} version of the name. + +\item[\Type{unw\_word\_t} \Var{segbase}] The segment-base value + that needs to be added to the segment-relative values stored in the + unwind-info. The exact meaning of this value is + architecture-specific. + +\item[\Type{unw\_word\_t} \Var{table\_len}] The length of the + unwind-info (\Var{table\_data}) counted in units of words + (\Type{unw\_word\_t}). + +\item[\Type{unw\_word\_t} \Var{table\_data}] A pointer to the actual + data encoding the unwind-info. The exact format is + architecture-specific (see architecture-specific sections below). + +\end{description} + +\subsection{Remote table-info format} + +The remote table-info format has the same basic purpose as the regular +table-info format. The only difference is that when \Prog{libunwind} +uses the unwind-info, it will keep the table data in the target +address-space (which may be remote). Consequently, the type of the +\Var{table\_data} member is \Type{unw\_word\_t} rather than a pointer. +This implies that \Prog{libunwind} will have to access the table-data +via the address-space's \Func{access\_mem}() call-back, rather than +through a direct memory reference. + +From the point of view of a runtime-code generator, the remote +table-info format offers no advantage and it is expected that such +generators will describe their procedures either with the proc-info +format or the normal table-info format. The main reason that the +remote table-info format exists is to enable the +address-space-specific \Func{find\_proc\_info}() callback (see +\SeeAlso{unw\_create\_addr\_space}(3)) to return unwind tables whose +data remains in remote memory. This can speed up unwinding (e.g., for +a debugger) because it reduces the amount of data that needs to be +loaded from remote memory. + +\section{Regions descriptors} + +A region descriptor is a variable length structure that describes how +each instruction in the region affects the frame state. Of course, +most instructions in a region usualy do not change the frame state and +for those, nothing needs to be recorded in the region descriptor. A +region descriptor is a structure of type +\Type{unw\_dyn\_region\_info\_t} and has the following members: +\begin{description} +\item[\Type{unw\_dyn\_region\_info\_t~*}\Var{next}] A pointer to the + next region. If this is the last region, \Var{next} is \Const{NULL}. +\item[\Type{int32\_t} \Var{insn\_count}] The length of the region in + instructions. Each instruction is assumed to have a fixed size (see + architecture-specific sections for details). The value of + \Var{insn\_count} may be negative in the last region of a procedure + (i.e., it may be negative only if \Var{next} is \Const{NULL}). A + negative value indicates that the region covers the last \emph{N} + instructions of the procedure, where \emph{N} is the absolute value + of \Var{insn\_count}. +\item[\Type{uint32\_t} \Var{op\_count}] The (allocated) length of + the \Var{op\_count} array. +\item[\Type{unw\_dyn\_op\_t} \Var{op}] An array of dynamic unwind + directives. See Section ``Dynamic unwind directives'' for a + description of the directives. +\end{description} +A region descriptor with an \Var{insn\_count} of zero is an +\emph{empty region} and such regions are perfectly legal. In fact, +empty regions can be useful to establish a particular frame state +before the start of another region. + +A single region list can be shared across multiple procedures provided +those procedures share a common prologue and epilogue (their bodies +may differ, of course). Normally, such procedures consist of a canned +prologue, the body, and a canned epilogue. This could be described by +two regions: one covering the prologue and one covering the epilogue. +Since the body length is variable, the latter region would need to +specify a negative value in \Var{insn\_count} such that +\Prog{libunwind} knows that the region covers the end of the procedure +(up to the address specified by \Var{end\_ip}). + +The region descriptor is a variable length structure to make it +possible to allocate all the necessary memory with a single +memory-allocation request. To facilitate the allocation of a region +descriptors \Prog{libunwind} provides a helper routine with the +following synopsis: + +\noindent +\Type{size\_t} \Func{\_U\_dyn\_region\_size}(\Type{int} \Var{op\_count}); + +This routine returns the number of bytes needed to hold a region +descriptor with space for \Var{op\_count} unwind directives. Note +that the length of the \Var{op} array does not have to match exactly +with the number of directives in a region. Instead, it is sufficient +if the \Var{op} array contains at least as many entries as there are +directives, since the end of the directives can always be indicated +with the \Const{UNW\_DYN\_STOP} directive. + +\section{Dynamic unwind directives} + +A dynamic unwind directive describes how the frame state changes +at a particular point within a region. The description is in +the form of a structure of type \Type{unw\_dyn\_op\_t}. This +structure has the following members: +\begin{description} +\item[\Type{int8\_t} \Var{tag}] The operation tag.

If the directive is always + active, this member should be set to the manifest constant + \Const{\_U\_QP\_TRUE} (this constant is defined for all + architectures, predicated or not). +\item[\Type{int16\_t} \Var{reg}] The number of the register affected + by the instruction. +\item[\Type{int32\_t} \Var{when}] The region-relative number of + the instruction to which this directive applies. For example, + a value of 0 means that the effect described by this directive + has taken place once the first instruction in the region has + executed. +\item[\Type{unw\_word\_t} \Var{val}] The value to be applied by the + operation tag. The exact meaning of this value varies by tag. See + Section ``Operation tags'' below. +\end{description} +It is perfectly legitimate to specify multiple dynamic unwind +directives with the same \Var{when} value, if a particular instruction +has a complex effect on the frame state. + +Empty regions by definition contain no actual instructions and as such +the directives are not tied to a particular instruction.

This includes both little\-endian Linux +and big\-endian HP\-UX. Furthermore, to make it possible for a single +library to unwind both 32\- and 64\-bit targets, the type +unw_word_t +is always defined to be 64 bits wide (independent +of the natural word\-size of the host). Having said that, the current +implementation has been tested only with IA\-64 Linux. +.PP +When targeting IA\-64, the libunwind +header file defines the +macro UNW_TARGET_IA64 +as 1 and the macro UNW_TARGET +as ``ia64\&'' (without the quotation marks). The former makes it +possible for platform\-dependent unwind code to use +conditional\-compilation to select an appropriate implementation. The +latter is useful for stringification purposes and to construct +target\-platform\-specific symbols. +.PP +One special feature of IA\-64 is the use of NaT bits to support +speculative execution. Often, NaT bits are thought of as the ``65\-th +bit\&'' of a general register. However, to make everything fit into +64\-bit wide unw_word_t +values, libunwind +treats the +NaT\-bits like separate boolean registers, whose 64\-bit value is either +TRUE (non\-zero) or FALSE (zero). +.PP +.SH MACHINE\-STATE + +.PP +The machine\-state (set of registers) that is accessible through +libunwind +depends on the type of stack frame that a cursor +points to. For normal frames, all ``preserved\&'' (callee\-saved) +registers are accessible. For signal\-trampoline frames, all registers +(including ``scratch\&'' (caller\-saved) registers) are accessible. Most +applications do not have to worry a\-priori about which registers are +accessible when. In case of doubt, it is always safe to \fItry\fP +to +access a register (via unw_get_reg() +or +unw_get_fpreg()) +and if the register isn\&'t accessible, the +call will fail with a return\-value of \-UNW_EBADREG\&. +.PP +As a special exception to the above general rule, scratch registers +r15\-r18 +are always accessible, even in normal +frames.

Moreover, the set of frame register values uniquely +identifies a stack frame. The IA\-64 architecture defines two stacks +(a memory and a register stack). Including the instruction\-pointer +(IP), this means there are three frame registers: +.TP +UNW_IA64_IP: + Contains the instruction pointer (IP, or +``program counter\&'') of the current stack frame. Given this value, +the remaining machine\-state corresponds to the register\-values that +were present in the CPU when it was just about to execute the +instruction pointed to by UNW_IA64_IP\&. +Bits 0 and 1 of +this frame\-register encode the slot number of the instruction. +\fBNote:\fP +Due to the way the call instruction works on IA\-64, +the slot number is usually zero, but can be non\-zero, e.g., in the +stack\-frame of a signal\-handler trampoline. +.TP +UNW_IA64_SP: + Contains the (memory) stack\-pointer +value (SP). +.TP +UNW_IA64_BSP: + Contains the register backing\-store +pointer (BSP). \fBNote:\fP +the value in this register is equal +to the contents of register ar.bsp +at the time the +instruction at UNW_IA64_IP +was about to begin execution. +.PP +.SS NORMAL REGISTER MACROS +.PP +The following normal register name macros are available: +.TP +UNW_IA64_GR: + The base\-index for general (integer) +registers.

This includes both little-endian Linux +and big-endian HP-UX. Furthermore, to make it possible for a single +library to unwind both 32- and 64-bit targets, the type +\Type{unw\_word\_t} is always defined to be 64 bits wide (independent +of the natural word-size of the host). Having said that, the current +implementation has been tested only with IA-64 Linux. + +When targeting IA-64, the \Prog{libunwind} header file defines the +macro \Const{UNW\_TARGET\_IA64} as 1 and the macro \Const{UNW\_TARGET} +as ``ia64'' (without the quotation marks). The former makes it +possible for platform-dependent unwind code to use +conditional-compilation to select an appropriate implementation. The +latter is useful for stringification purposes and to construct +target-platform-specific symbols. + +One special feature of IA-64 is the use of NaT bits to support +speculative execution. Often, NaT bits are thought of as the ``65-th +bit'' of a general register. However, to make everything fit into +64-bit wide \Type{unw\_word\_t} values, \Prog{libunwind} treats the +NaT-bits like separate boolean registers, whose 64-bit value is either +TRUE (non-zero) or FALSE (zero). + + +\section{Machine-State} + +The machine-state (set of registers) that is accessible through +\Prog{libunwind} depends on the type of stack frame that a cursor +points to. For normal frames, all ``preserved'' (callee-saved) +registers are accessible. For signal-trampoline frames, all registers +(including ``scratch'' (caller-saved) registers) are accessible. Most +applications do not have to worry a-priori about which registers are +accessible when. In case of doubt, it is always safe to \emph{try} to +access a register (via \Func{unw\_get\_reg}() or +\Func{unw\_get\_fpreg}()) and if the register isn't accessible, the +call will fail with a return-value of \texttt{-}\Const{UNW\_EBADREG}. + +As a special exception to the above general rule, scratch registers +\texttt{r15}-\texttt{r18} are always accessible, even in normal +frames. This makes it possible to pass arguments, e.g., to exception +handlers. + +For a detailed description of the IA-64 register usage convention, +please see the ``Itanium Software Conventions and Runtime Architecture +Guide'', available at: +\begin{center} + \URL{http://www.intel.com/design/itanium/downloads/245358.htm} +\end{center} + + +\section{Register Names} + +The IA-64-version of \Prog{libunwind} defines three kinds of register +name macros: frame-register macros, normal register macros, and +convenience macros.

Also, when using \Var{\_UPT\_accessors}, \emph{all} +the callback routines will be linked into the application, even if +they are never actually called. + +Next, the application can turn on ptrace-mode on the target process, +either by forking a new process, invoking \Const{PTRACE\_TRACEME}, and +then starting the target program (via \Func{execve}(2)), or by +directly attaching to an already running process (via +\Const{PTRACE\_ATTACH}). Either way, once the process-ID (pid) of the +target process is known, a \Prog{\_UPT}-info-structure can be created +by calling \Func{\_UPT\_create}(), passing the pid of the target process +as the only argument. The returned void-pointer then needs to be +passed as the ``argument'' pointer (third argument) to +\Func{unw\_init\_remote}(). + +The \Func{\_UPT\_resume}() routine can be used to resume execution of +the target process. It simply invokes \Func{ptrace}(2) with a command +value of \Const{PTRACE\_CONT}. + +When the application is done using \Prog{libunwind} on the target +process, \Func{\_UPT\_destroy}() needs to be called, passing it the +void-pointer that was returned by the corresponding call to +\Func{\_UPT\_create}(). This ensures that all memory and other +resources are freed up. + +\section{Availability} + +Since \Func{ptrace}(2) works within a single machine only, the +\Prog{\_UPT}-facility by definition is not available in +\Prog{libunwind}-versions configured for cross-unwinding. + +\section{Thread Safety} + +The \Prog{\_UPT}-facility assumes that a single \Prog{\_UPT}-info +structure is never shared between threads.

This is called \fIlocal\fP +unwinding. Say +you want to unwind the stack while executing in some function +F(). +In this function, you would call unw_getcontext() +to get a snapshot of the CPU registers (machine\-state). Then you +initialize an \fIunwind cursor\fP +based on this snapshot. This is +done with a call to unw_init_local(). +The cursor now points +to the current frame, that is, the stack frame that corresponds to the +current activation of function F(). +The unwind cursor can then +be moved ``up\&'' (towards earlier stack frames) by calling +unw_step(). +By repeatedly calling this routine, you can +uncover the entire call\-chain that led to the activation of function +F(). +A positive return value from unw_step() +indicates +that there are more frames in the chain, zero indicates that the end +of the chain has been reached, and any negative value indicates that +some sort of error has occurred. +.PP +While it is not possible to directly move the unwind cursor in the +``down\&'' direction (towards newer stack frames), this effect can be +achieved by making copies of an unwind cursor. For example, a program +that sometimes has to move ``down\&'' by one stack frame could maintain +two cursor variables: ``curr\&'' +and ``prev\&''\&. +The former +would be used as the current cursor and prev +would be maintained +as the ``previous frame\&'' cursor by copying the contents of curr +to prev +right before calling unw_step(). +With this +approach, the program could move one step ``down\&'' simply by copying +back prev +to curr +whenever that is necessary. In the most +extreme case, a program could maintain a separate cursor for each call +frame and that way it could move up and down the callframe\-chain at +will. +.PP +Given an unwind cursor, it is possible to read and write the CPU +registers that were preserved for the current stack frame (as +identified by the cursor). Libunwind +provides several routines +for this purpose: unw_get_reg() +reads an integer (general) +register, unw_get_fpreg() +reads a floating\-point register, +unw_set_reg() +writes an integer register, and +unw_set_fpreg() +writes a floating\-point register. Note that, +by definition, only the \fIpreserved\fP +machine state can be accessed +during an unwind operation. Normally, this state consists of the +\fIcallee\-saved\fP +(``preserved\&'') registers. However, in some +special circumstances (e.g., in a signal handler trampoline), even the +\fIcaller\-saved\fP +(``scratch\&'') registers are preserved in the stack +frame and, in those cases, libunwind +will grant access to them +as well. The exact set of registers that can be accessed via the +cursor depends, of course, on the platform. However, there are two +registers that can be read on all platforms: the instruction pointer +(IP), sometimes also known as the ``program counter\&'', and the stack +pointer (SP). In libunwind, +these registers are identified by +the macros UNW_REG_IP +and UNW_REG_SP, +respectively. +.PP +Besides just moving the unwind cursor and reading/writing saved +registers, libunwind +also provides the ability to resume +execution at an arbitrary stack frame. As you might guess, this is +useful for implementing non\-local gotos and the exception handling +needed by some high\-level languages such as Java. Resuming execution +with a particular stack frame simply requires calling +unw_resume() +and passing the cursor identifying the target +frame as the only argument. +.PP +Normally, libunwind +supports both local and remote unwinding +(the latter will be explained in the next section). However, if you +tell libunwind that your program only needs local unwinding, then a +special implementation can be selected which may run much faster than +the generic implementation which supports both kinds of unwinding. To +select this optimized version, simply define the macro +UNW_LOCAL_ONLY +before including the headerfile +\&. +It is perfectly OK for a single program to +employ both local\-only and generic unwinding. That is, whether or not +UNW_LOCAL_ONLY +is defined is a choice that each source\-file +(compilation\-unit) can make on its own. Independent of the setting(s) +of UNW_LOCAL_ONLY, +you\&'ll always link the same library into +the program (normally \fB\-l\fPunwind). +Furthermore, the +portion of libunwind +that manages unwind\-info for dynamically +generated code is not affected by the setting of +UNW_LOCAL_ONLY\&. +.PP +If we put all of the above together, here is how we could use +libunwind +to write a function ``show_backtrace()\&'' +which prints a classic stack trace: +.PP +.Vb +#define UNW_LOCAL_ONLY +#include + +void show_backtrace (void) { + unw_cursor_t cursor; unw_context_t uc; + unw_word_t ip, sp; + + unw_getcontext(&uc); + unw_init_local(&cursor, &uc); + while (unw_step(&cursor) > 0) { + unw_get_reg(&cursor, UNW_REG_IP, &ip); + unw_get_reg(&cursor, UNW_REG_SP, &sp); + printf ("ip = %lx, sp = %lx\\n", (long) ip, (long) sp); + } +} +.Ve +.PP +.SH REMOTE UNWINDING + +.PP +Libunwind +can also be used to unwind a stack in a ``remote\&'' +process. Here, ``remote\&'' may mean another process on the same +machine or even a process on a completely different machine from the +one that is running libunwind\&. +Remote unwinding is typically +used by debuggers and instruction\-set simulators, for example. +.PP +Before you can unwind a remote process, you need to create a new +address\-space object for that process. This is achieved with the +unw_create_addr_space() +routine. The routine takes two +arguments: a pointer to a set of \fIaccessor\fP +routines and an +integer that specifies the byte\-order of the target process. The +accessor routines provide libunwind +with the means to +communicate with the remote process. In particular, there are +callbacks to read and write the process\&'s memory, its registers, and +to access unwind information which may be needed by libunwind\&. +.PP +With the address space created, unwinding can be initiated by a call +to unw_init_remote(). +This routine is very similar to +unw_init_local(), +except that it takes an address\-space +object and an opaque pointer as arguments. The routine uses these +arguments to fetch the initial machine state. Libunwind +never +uses the opaque pointer on its own, but instead just passes it on to +the accessor (callback) routines. Typically, this pointer is used to +select, e.g., the thread within a process that is to be unwound. +.PP +Once a cursor has been initialized with unw_init_remote(), +unwinding works exactly like in the local case. That is, you can use +unw_step() +to move ``up\&'' in the call\-chain, read and write +registers, or resume execution at a particular stack frame by calling +unw_resume\&. +.PP +.SH CROSS\-PLATFORM AND MULTI\-PLATFORM UNWINDING + +.PP +Libunwind +has been designed to enable unwinding across +platforms (architectures). Indeed, a single program can use +libunwind +to unwind an arbitrary number of target platforms, +all at the same time! +.PP +We call the machine that is running libunwind +the \fIhost\fP +and the machine that is running the process being unwound the +\fItarget\fP\&. +If the host and the target platform are the same, we +call it \fInative\fP +unwinding. If they differ, we call it +\fIcross\-platform\fP +unwinding. +.PP +The principle behind supporting native, cross\-platform, and +multi\-platform unwinding is very simple: for native unwinding, a +program includes +and uses the linker switch +\fB\-l\fPunwind\&. +For cross\-platform unwinding, a program +includes +and uses the linker +switch \fB\-l\fPunwind\-PLAT, +where PLAT +is the name +of the target platform (e.g., ia64 +for IA\-64, hppa\-elf +for ELF\-based HP PA\-RISC, or x86 +for 80386). Multi\-platform +unwinding works exactly like cross\-platform unwinding, the only +limitation is that a single source file (compilation unit) can include +at most one libunwind +header file. In other words, the +platform\-specific support for each supported target needs to be +isolated in separate source files\-\-\-a limitation that shouldn\&'t be an +issue in practice. +.PP +Note that, by definition, local unwinding is possible only for the +native case. Attempting to call, e.g., unw_local_init() +when +targeting a cross\-platform will result in a link\-time error +(unresolved references). +.PP +.SH THREAD\- AND SIGNAL\-SAFETY + +.PP +All libunwind +routines are thread\-safe. What this means is +that multiple threads may use libunwind +simulatenously. +However, any given cursor may be accessed by only one thread at +any given time. +.PP +To ensure thread\-safety, some libunwind +routines may have to +use locking. Such routines \fImust not\fP +be called from signal +handlers (directly or indirectly) and are therefore \fInot\fP +signal\-safe. The manual page for each libunwind +routine +identifies whether or not it is signal\-safe, but as a general rule, +any routine that may be needed for \fIlocal\fP +unwinding is +signal\-safe (e.g., unw_step() +for local unwinding is +signal\-safe). For remote\-unwinding, \fInone\fP +of the +libunwind +routines are guaranteed to be signal\-safe. +.PP +.SH UNWINDING THROUGH DYNAMICALLY GENERATED CODE + +.PP +Libunwind +provides the routines _U_dyn_register() +and +_U_dyn_cancel() +to register/cancel the information required to +unwind through code that has been generated at runtime (e.g., by a +just\-in\-time (JIT) compiler). It is important to register the +information for \fIall\fP +dynamically generated code because +otherwise, a debugger may not be able to function properly or +high\-level language exception handling may not work as expected. +.PP +The interface for registering and canceling dynamic unwind info has +been designed for maximum efficiency, so as to minimize the +performance impact on JIT\-compilers. In particular, both routines are +guaranteed to execute in ``constant time\&'' (O(1)) and the +data\-structure encapsulating the dynamic unwind info has been designed +to facilitate sharing, such that similar procedures can share much of +the underlying information. +.PP +For more information on the libunwind +support for dynamically +generated code, see libunwind\-dynamic(3)\&. +.PP +.SH CACHING OF UNWIND INFO + +.PP +To speed up execution, libunwind +may aggressively cache the +information it needs to perform unwinding. If a process changes +during its lifetime, this creates a risk of libunwind +using +stale data. For example, this would happen if libunwind +were +to cache information about a shared library which later on gets +unloaded (e.g., via \fIdlclose\fP(3)). +.PP +To prevent the risk of using stale data, libunwind +provides two +facilities: first, it is possible to flush the cached information +associated with a specific address range in the target process (or the +entire address space, if desired). This functionality is provided by +unw_flush_cache(). +The second facility is provided by +unw_set_caching_policy(), +which lets a program +select the exact caching policy in use for a given address\-space +object.

This is called \emph{local} unwinding. Say +you want to unwind the stack while executing in some function +\Func{F}(). In this function, you would call \Func{unw\_getcontext}() +to get a snapshot of the CPU registers (machine-state). Then you +initialize an \emph{unwind~cursor} based on this snapshot. This is +done with a call to \Func{unw\_init\_local}(). The cursor now points +to the current frame, that is, the stack frame that corresponds to the +current activation of function \Func{F}(). The unwind cursor can then +be moved ``up'' (towards earlier stack frames) by calling +\Func{unw\_step}(). By repeatedly calling this routine, you can +uncover the entire call-chain that led to the activation of function +\Func{F}(). A positive return value from \Func{unw\_step}() indicates +that there are more frames in the chain, zero indicates that the end +of the chain has been reached, and any negative value indicates that +some sort of error has occurred. + +While it is not possible to directly move the unwind cursor in the +``down'' direction (towards newer stack frames), this effect can be +achieved by making copies of an unwind cursor. For example, a program +that sometimes has to move ``down'' by one stack frame could maintain +two cursor variables: ``\Var{curr}'' and ``\Var{prev}''. The former +would be used as the current cursor and \Var{prev} would be maintained +as the ``previous frame'' cursor by copying the contents of \Var{curr} +to \Var{prev} right before calling \Func{unw\_step}(). With this +approach, the program could move one step ``down'' simply by copying +back \Var{prev} to \Var{curr} whenever that is necessary. In the most +extreme case, a program could maintain a separate cursor for each call +frame and that way it could move up and down the callframe-chain at +will. + +Given an unwind cursor, it is possible to read and write the CPU +registers that were preserved for the current stack frame (as +identified by the cursor). \Prog{Libunwind} provides several routines +for this purpose: \Func{unw\_get\_reg}() reads an integer (general) +register, \Func{unw\_get\_fpreg}() reads a floating-point register, +\Func{unw\_set\_reg}() writes an integer register, and +\Func{unw\_set\_fpreg}() writes a floating-point register. Note that, +by definition, only the \emph{preserved} machine state can be accessed +during an unwind operation. Normally, this state consists of the +\emph{callee-saved} (``preserved'') registers. However, in some +special circumstances (e.g., in a signal handler trampoline), even the +\emph{caller-saved} (``scratch'') registers are preserved in the stack +frame and, in those cases, \Prog{libunwind} will grant access to them +as well. The exact set of registers that can be accessed via the +cursor depends, of course, on the platform. However, there are two +registers that can be read on all platforms: the instruction pointer +(IP), sometimes also known as the ``program counter'', and the stack +pointer (SP). In \Prog{libunwind}, these registers are identified by +the macros \Const{UNW\_REG\_IP} and \Const{UNW\_REG\_SP}, +respectively. + +Besides just moving the unwind cursor and reading/writing saved +registers, \Prog{libunwind} also provides the ability to resume +execution at an arbitrary stack frame. As you might guess, this is +useful for implementing non-local gotos and the exception handling +needed by some high-level languages such as Java. Resuming execution +with a particular stack frame simply requires calling +\Func{unw\_resume}() and passing the cursor identifying the target +frame as the only argument. + +Normally, \Prog{libunwind} supports both local and remote unwinding +(the latter will be explained in the next section). However, if you +tell libunwind that your program only needs local unwinding, then a +special implementation can be selected which may run much faster than +the generic implementation which supports both kinds of unwinding. To +select this optimized version, simply define the macro +\Const{UNW\_LOCAL\_ONLY} before including the headerfile +\File{$<$libunwind.h$>$}. It is perfectly OK for a single program to +employ both local-only and generic unwinding. That is, whether or not +\Const{UNW\_LOCAL\_ONLY} is defined is a choice that each source-file +(compilation-unit) can make on its own. Independent of the setting(s) +of \Const{UNW\_LOCAL\_ONLY}, you'll always link the same library into +the program (normally \Opt{-l}\File{unwind}). Furthermore, the +portion of \Prog{libunwind} that manages unwind-info for dynamically +generated code is not affected by the setting of +\Const{UNW\_LOCAL\_ONLY}. + +If we put all of the above together, here is how we could use +\Prog{libunwind} to write a function ``\Func{show\_backtrace}()'' +which prints a classic stack trace: + +\begin{verbatim} +#define UNW_LOCAL_ONLY +#include + +void show_backtrace (void) { + unw_cursor_t cursor; unw_context_t uc; + unw_word_t ip, sp; + + unw_getcontext(&uc); + unw_init_local(&cursor, &uc); + while (unw_step(&cursor) > 0) { + unw_get_reg(&cursor, UNW_REG_IP, &ip); + unw_get_reg(&cursor, UNW_REG_SP, &sp); + printf ("ip = %lx, sp = %lx\n", (long) ip, (long) sp); + } +} +\end{verbatim} + + +\section{Remote Unwinding} + +\Prog{Libunwind} can also be used to unwind a stack in a ``remote'' +process. Here, ``remote'' may mean another process on the same +machine or even a process on a completely different machine from the +one that is running \Prog{libunwind}. Remote unwinding is typically +used by debuggers and instruction-set simulators, for example. + +Before you can unwind a remote process, you need to create a new +address-space object for that process. This is achieved with the +\Func{unw\_create\_addr\_space}() routine. The routine takes two +arguments: a pointer to a set of \emph{accessor} routines and an +integer that specifies the byte-order of the target process. The +accessor routines provide \Func{libunwind} with the means to +communicate with the remote process. In particular, there are +callbacks to read and write the process's memory, its registers, and +to access unwind information which may be needed by \Func{libunwind}. + +With the address space created, unwinding can be initiated by a call +to \Func{unw\_init\_remote}(). This routine is very similar to +\Func{unw\_init\_local}(), except that it takes an address-space +object and an opaque pointer as arguments. The routine uses these +arguments to fetch the initial machine state. \Prog{Libunwind} never +uses the opaque pointer on its own, but instead just passes it on to +the accessor (callback) routines. Typically, this pointer is used to +select, e.g., the thread within a process that is to be unwound. + +Once a cursor has been initialized with \Func{unw\_init\_remote}(), +unwinding works exactly like in the local case. That is, you can use +\Func{unw\_step}() to move ``up'' in the call-chain, read and write +registers, or resume execution at a particular stack frame by calling +\Func{unw\_resume}. + + +\section{Cross-platform and Multi-platform Unwinding} + +\Prog{Libunwind} has been designed to enable unwinding across +platforms (architectures). Indeed, a single program can use +\Prog{libunwind} to unwind an arbitrary number of target platforms, +all at the same time! + +We call the machine that is running \Prog{libunwind} the \emph{host} +and the machine that is running the process being unwound the +\emph{target}. If the host and the target platform are the same, we +call it \emph{native} unwinding. If they differ, we call it +\emph{cross-platform} unwinding. + +The principle behind supporting native, cross-platform, and +multi-platform unwinding is very simple: for native unwinding, a +program includes \File{$<$libunwind.h$>$} and uses the linker switch +\Opt{-l}\File{unwind}. For cross-platform unwinding, a program +includes \File{$<$libunwind-}\Var{PLAT}\File{.h$>$} and uses the linker +switch \Opt{-l}\File{unwind-}\Var{PLAT}, where \Var{PLAT} is the name +of the target platform (e.g., \File{ia64} for IA-64, \File{hppa-elf} +for ELF-based HP PA-RISC, or \File{x86} for 80386). Multi-platform +unwinding works exactly like cross-platform unwinding, the only +limitation is that a single source file (compilation unit) can include +at most one \Prog{libunwind} header file. In other words, the +platform-specific support for each supported target needs to be +isolated in separate source files---a limitation that shouldn't be an +issue in practice. + +Note that, by definition, local unwinding is possible only for the +native case. Attempting to call, e.g., \Func{unw\_local\_init}() when +targeting a cross-platform will result in a link-time error +(unresolved references). + + +\section{Thread- and Signal-Safety} + + +All \Prog{libunwind} routines are thread-safe. What this means is +that multiple threads may use \Prog{libunwind} simulatenously. +However, any given cursor may be accessed by only one thread at +any given time. + +To ensure thread-safety, some \Prog{libunwind} routines may have to +use locking. Such routines \emph{must~not} be called from signal +handlers (directly or indirectly) and are therefore \emph{not} +signal-safe. The manual page for each \Prog{libunwind} routine +identifies whether or not it is signal-safe, but as a general rule, +any routine that may be needed for \emph{local} unwinding is +signal-safe (e.g., \Func{unw\_step}() for local unwinding is +signal-safe). For remote-unwinding, \emph{none} of the +\Prog{libunwind} routines are guaranteed to be signal-safe. + + +\section{Unwinding Through Dynamically Generated Code} + +\Func{Libunwind} provides the routines \Func{\_U\_dyn\_register}() and +\Func{\_U\_dyn\_cancel}() to register/cancel the information required to +unwind through code that has been generated at runtime (e.g., by a +just-in-time (JIT) compiler). It is important to register the +information for \emph{all} dynamically generated code because +otherwise, a debugger may not be able to function properly or +high-level language exception handling may not work as expected. + +The interface for registering and canceling dynamic unwind info has +been designed for maximum efficiency, so as to minimize the +performance impact on JIT-compilers. In particular, both routines are +guaranteed to execute in ``constant time'' (O(1)) and the +data-structure encapsulating the dynamic unwind info has been designed +to facilitate sharing, such that similar procedures can share much of +the underlying information. + +For more information on the \Prog{libunwind} support for dynamically +generated code, see \SeeAlso{libunwind-dynamic(3)}. + + +\section{Caching of Unwind Info} + +To speed up execution, \Prog{libunwind} may aggressively cache the +information it needs to perform unwinding. If a process changes +during its lifetime, this creates a risk of \Prog{libunwind} using +stale data. For example, this would happen if \Prog{libunwind} were +to cache information about a shared library which later on gets +unloaded (e.g., via \Cmd{dlclose}{3}). + +To prevent the risk of using stale data, \Prog{libunwind} provides two +facilities: first, it is possible to flush the cached information +associated with a specific address range in the target process (or the +entire address space, if desired). This functionality is provided by +\Func{unw\_flush\_cache}(). The second facility is provided by +\Func{unw\_set\_caching\_policy}(), which lets a program +select the exact caching policy in use for a given address-space +object. In particular, by selecting the policy +\Const{UNW\_CACHE\_NONE}, it is possible to turn off caching +completely, therefore eliminating the risk of stale data alltogether +(at the cost of slower execution). By default, caching is enabled for +local unwinding only. + + +\section{Files} + +\begin{Description} +\item[\File{libunwind.h}] Headerfile to include for native (same + platform) unwinding. +\item[\File{libunwind-}\Var{PLAT}\File{.h}] Headerfile to include when + the unwind target runs on platform \Var{PLAT}.

Thus +unw_resume() +does not return in this case. Restoring the +machine state normally involves restoring the ``preserved\&'' +(callee\-saved) registers. However, if execution in any of the stack +frames younger (more deeply nested) than the one identified by +cp +was interrupted by a signal, then unw_resume() +will +restore all registers as well as the signal mask. Attempting to call +unw_resume() +on a cursor which identifies the stack frame of +another thread results in undefined behavior (e.g., the program may +crash). +.PP +For remote unwinding, unw_resume() +installs the machine state +identified by the cursor by calling the access_reg +and +access_fpreg +accessor callbacks as needed. Once that is +accomplished, the resume +accessor callback is invoked. The +unw_resume +routine then returns normally (that is, unlikely +for local unwinding, unw_resume +will always return for remote +unwinding). +.PP +Most platforms reserve some registers to pass arguments to exception +handlers (e.g., IA\-64 uses r15\-r18 +for this +purpose). These registers are normally treated like ``scratch\&'' +registers. However, if libunwind +is used to set an exception +argument register to a particular value (e.g., via +unw_set_reg()), +then unw_resume() +will install this +value as the contents of the register. In other words, the exception +handling arguments are installed even in cases where normally only the +``preserved\&'' registers are restored. +.PP +Note that unw_resume() +does \fInot\fP +invoke any unwind +handlers (aka, ``personality routines\&''). If a program needs this, it +will have to do so on its own by obtaining the unw_proc_info_t +of each unwound frame and appropriately processing its unwind handler +and language\-specific data area (lsda).

The behavior of this routine differs +slightly for local and remote unwinding. + +For local unwinding, \Func{unw\_resume}() restores the machine state +and then directly resumes execution in the target stack frame. Thus +\Func{unw\_resume}() does not return in this case. Restoring the +machine state normally involves restoring the ``preserved'' +(callee-saved) registers. However, if execution in any of the stack +frames younger (more deeply nested) than the one identified by +\Var{cp} was interrupted by a signal, then \Func{unw\_resume}() will +restore all registers as well as the signal mask. Attempting to call +\Func{unw\_resume}() on a cursor which identifies the stack frame of +another thread results in undefined behavior (e.g., the program may +crash). + +For remote unwinding, \Func{unw\_resume}() installs the machine state +identified by the cursor by calling the \Func{access\_reg} and +\Func{access\_fpreg} accessor callbacks as needed. Once that is +accomplished, the \Func{resume} accessor callback is invoked. The +\Func{unw\_resume} routine then returns normally (that is, unlikely +for local unwinding, \Func{unw\_resume} will always return for remote +unwinding). + +Most platforms reserve some registers to pass arguments to exception +handlers (e.g., IA-64 uses \texttt{r15}-\texttt{r18} for this +purpose). These registers are normally treated like ``scratch'' +registers. However, if \Prog{libunwind} is used to set an exception +argument register to a particular value (e.g., via +\Func{unw\_set\_reg}()), then \Func{unw\_resume}() will install this +value as the contents of the register. In other words, the exception +handling arguments are installed even in cases where normally only the +``preserved'' registers are restored. + +Note that \Func{unw\_resume}() does \emph{not} invoke any unwind +handlers (aka, ``personality routines''). If a program needs this, it +will have to do so on its own by obtaining the \Type{unw\_proc\_info\_t} +of each unwound frame and appropriately processing its unwind handler +and language-specific data area (lsda).

The exception-header is self-describing in the + sense that the format of the addresses contained in it is expressed + as a one-byte type-descriptor called a "pointer-encoding" (PE). + + The exception header encodes the address of the .eh_frame section + and optionally contains a binary search table for the + Frame Descriptor Entries (FDEs) in the .eh_frame. The contents of + .eh_frame has the format described by the DWARF v3 standard + (http://www.eagercon.com/dwarf/dwarf3std.htm), except that code + addresses may be encoded in different ways. Also, .eh_frame has + augmentations that allow encoding a language-specific data-area + (LSDA) pointer and a pointer to a personality-routine. + + Details: + + The Common Information Entry (CIE) associated with an FDE may + contain an augmentation string. Each character in this string has + a specific meaning and either one or two associated operands. The + operands are stored in an augmentation body which appears right + after the "return_address_register" member and before the + "initial_instructions" member. The operands appear in the order + in which the characters appear in the string. For example, if the + augmentation string is "zL", the operand for 'z' would be first in + the augmentation body and the operand for 'L' would be second. + The following characters are supported for the CIE augmentation + string: + + 'z': The operand for this character is a uleb128 value that gives the + length of the CIE augmentation body, not counting the length + of the uleb128 operand itself. If present, this code must + appear as the first character in the augmentation body. + + 'L': Indicates that the FDE's augmentation body contains an LSDA + pointer. The operand for this character is a single byte + that specifies the pointer-encoding (PE) that is used for + the LSDA pointer. + + 'R': Indicates that the code-pointers (FDE members + "initial_location" and "address_range" and the operand for + DW_CFA_set_loc) in the FDE have a non-default encoding. The + operand for this character is a single byte that specifies + the pointer-encoding (PE) that is used for the + code-pointers. Note: the "address_range" member is always + encoded as an absolute value. Apart from that, the specified + FDE pointer-encoding applies. + + 'P': Indicates the presence of a personality routine (handler). + The first operand for this character specifies the + pointer-encoding (PE) that is used for the second operand, + which specifies the address of the personality routine. + + If the augmentation string contains any other characters, the + remainder of the augmentation string should be ignored. + Furthermore, if the size of the augmentation body is unknown + (i.e., 'z' is not the first character of the augmentation string), + then the entire CIE as well all associated FDEs must be ignored. + + A Frame Descriptor Entries (FDE) may contain an augmentation body + which, if present, appears right after the "address_range" member + and before the "instructions" member.

If any interfaces have been added, removed, or changed since the +# last update, increment current, and set revision to 0. + +# 5. If any interfaces have been added since the last public release, +# then increment age. + +# 6.
