+ Version 2, June 1991
+

+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) 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
+this service 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 make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. 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.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+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
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the 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 a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE 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.
+
+ END OF TERMS AND CONDITIONS
+\f
+ 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
+convey 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 2 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, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision 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, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+

+
+This 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 Library General
+Public License instead of this License.

+The configuration and build scripts for this package were generated by
+automake/autoconf. "configure --prefix=<install dir>; make; make install"
+in this directory should work.
+
+Note that much of the content of this library is in the header files.
+
+However two small libraries are built and installed:
+
+- libatomic_ops.a is a support library, which is not needed on some platforms.
+ This is intended to be usable, under some mild restrictions, in free or
+ proprietary code, as are all the header files. See doc/LICENSING.txt.
+- libatomic_ops_gpl.a contains some higher level facilities. This code is
+ currently covered by the GPL. The contents currently correspond to
+ the headers atomic_ops_stack.h and atomic_ops_malloc.h.

+- That does more interesting things in signal handlers.
+- Makes more effective use of multiprocessors by allowing you to write
+ clever lock-free code. Note that such code is very difficult to get
+ right, and will unavoidably be less portable than lock-based code. It
+ ia also not always faster than lock-based code. But it may occasionally
+ be a large performance win.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$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 $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# 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

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) 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
+this service 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 make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. 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.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+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
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the 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 a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE 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.
+
+ END OF TERMS AND CONDITIONS
+\f
+ 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
+convey 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 2 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, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision 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, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This 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 Library General
+Public License instead of this License.
--- /dev/null
+Our intent is to make it easy to use libatomic_ops, in
+both free and proprietary software. Hence most code that we expect to be
+linked into a client application is covered by an MIT-style license.
+
+A few library routines are covered by the GNU General Public License.
+These are put into a separate library, libatomic_ops_gpl.a .
+
+The low-level part of the library is mostly covered by the following
+license:
+
+----------------------------------------
+
+Copyright (c) ...
+
+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. IN NO EVENT SHALL THE
+AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER
+LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM,
+OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
+SOFTWARE.
+
+--------------------------------
+
+A few files in the sysdeps directory were inherited in part from the
+Boehm-Demers-Weiser conservative garbage collector, and are covered by
+its license, which is similar in spirit:
+
+--------------------------------
+
+Copyright (c) ...
+
+THIS MATERIAL IS PROVIDED AS IS, WITH ABSOLUTELY NO WARRANTY EXPRESSED
+OR IMPLIED. ANY USE IS AT YOUR OWN RISK.
+
+Permission is hereby granted to use or copy this program
+for any purpose, provided the above notices are retained on all copies.
+Permission to modify the code and to distribute modified code is granted,
+provided the above notices are retained, and a notice that the code was
+modified is included with the above copyright notice.
+
+----------------------------------
+
+A few files are covered by the GNU General Public License. (See file
+"COPYING".) This applies only to test code, sample applications,
+and the libatomic_ops_gpl portion of the library.
+Thus libatomic_ops_gpl should generally not be linked into proprietary code.
+(This distinction was motivated by patent considerations.)
+
+It is possible that the license of the GPL pieces may be changed for
+future versions to make them more consistent with the rest of the package.
+If you submit patches, and have strong preferences about licensing, please
+express them.

+.NOEXPORT:
--- /dev/null
+Usage:
+
+0) If possible, do this on a multiprocessor, especially if you are planning
+on modifying or enhancing the package. It will work on a uniprocessor,
+but the tests are much more likely to pass in the presence of serious problems.
+
+1) Type ./configure --prefix=<install dir>; make; make check
+in the directory containing unpacked source. The usual GNU build machinery
+is used, except that only static, but position-independent, libraries
+are normally built. On Windows, read README_win32.txt instead.
+
+2) Applications should include atomic_ops.h. Nearly all operations
+are implemented by header files included from it. It is sometimes
+necessary, and always recommended to also link against libatomic_ops.a.
+To use the almost non-blocking stack or malloc implementations,
+see the corresponding README files, and also link against libatomic_gpl.a
+before linking against libatomic_ops.a.
+
+OVERVIEW:
+Atomic_ops.h defines a large collection of operations, each one of which is
+a combination of an (optional) atomic memory operation, and a memory barrier.
+Also defines associated feature-test macros to determine whether a particular
+operation is available on the current target hardware (either directly or
+by synthesis). This is an attempt to replace various existing files with
+similar goals, since they usually do not handle differences in memory
+barrier styles with sufficient generality.
+
+If this is included after defining AO_REQUIRE_CAS, then the package
+will make an attempt to emulate compare-and-swap in a way that (at least
+on Linux) should still be async-signal-safe. As a result, most other
+atomic operations will then be defined using the compare-and-swap
+emulation. This emulation is slow, since it needs to disable signals.
+And it needs to block in case of contention. If you care about performance
+on a platform that can't directly provide compare-and-swap, there are
+probably better alternatives. But this allows easy ports to some such
+platforms (e.g. PA_RISC). The option is ignored if compare-and-swap
+can be implemented directly.
+
+If atomic_ops.h is included after defining AO_USE_PTHREAD_DEFS, then all
+atomic operations will be emulated with pthread locking. This is NOT
+async-signal-safe. And it is slow. It is intended primarily for debugging
+of the atomic_ops package itself.
+
+Note that the implementation reflects our understanding of real processor
+behavior. This occasionally diverges from the documented behavior. (E.g.
+the documented X86 behavior seems to be weak enough that it is impractical
+to use. Current real implementations appear to be much better behaved.)
+We of course are in no position to guarantee that future processors
+(even HPs) will continue to behave this way, though we hope they will.
+
+This is a work in progress. Corrections/additions for other platforms are
+greatly appreciated. It passes rudimentary tests on X86, Itanium, and
+Alpha.
+
+OPERATIONS:
+
+Most operations operate on values of type AO_t, which are unsigned integers
+whose size matches that of pointers on the given architecture. Exceptions
+are:
+
+- AO_test_and_set operates on AO_TS_t, which is whatever size the hardware
+supports with good performance. In some cases this is the length of a cache line.
+In some cases it is a byte. In many cases it is equivalent to AO_t.
+
+- A few operations are implemented on smaller or larger size integers.
+Such operations are indicated by the appropriate prefix:
+
+AO_char_... Operates on unsigned char values.
+AO_short_... Operates on unsigned short values.
+AO_int_... Operates on unsigned int values.
+
+(Currently a very limited selection of these is implemented. We're
+working on it.)
+
+The defined operations are all of the form AO_[<size>_]<op><barrier>(<args>).
+
+The <op> component specifies an atomic memory operation. It may be
+one of the following, where the corresponding argument and result types
+are also specified:
+
+void nop()
+ No atomic operation. The barrier may still be useful.
+AO_t load(volatile AO_t * addr)
+ Atomic load of *addr.
+void store(volatile AO_t * addr, AO_t new_val)
+ Atomically store new_val to *addr.
+AO_t fetch_and_add(volatile AO_t *addr, AO_t incr)
+ Atomically add incr to *addr, and return the original value of *addr.
+AO_t fetch_and_add1(volatile AO_t *addr)
+ Equivalent to AO_fetch_and_add(addr, 1).
+AO_t fetch_and_sub1(volatile AO_t *addr)
+ Equivalent to AO_fetch_and_add(addr, (AO_t)(-1)).
+void or(volatile AO_t *addr, AO_t incr)
+ Atomically or incr into *addr.
+int compare_and_swap(volatile AO_t * addr, AO_t old_val, AO_t new_val)
+ Atomically compare *addr to old_val, and replace *addr by new_val
+ if the first comparison succeeds. Returns nonzero if the comparison
+ succeeded and *addr was updated.
+AO_TS_VAL_t test_and_set(volatile AO_TS_t * addr)
+ Atomically read the binary value at *addr, and set it. AO_TS_VAL_t
+ is an enumeration type which includes the two values AO_TS_SET and
+ and AO_TS_CLEAR. An AO_TS_t location is capable of holding an
+ AO_TS_VAL_t, but may be much larger, as dictated by hardware
+ constraints. Test_and_set logically sets the value to AO_TS_SET.
+ It may be reset to AO_TS_CLEAR with the AO_CLEAR(AO_TS_t *) macro.
+ AO_TS_t locations should be initialized to AO_TS_INITIALIZER.
+ The values of AO_TS_SET and AO_TS_CLEAR are hardware dependent.
+ (On PA-RISC, AO_TS_SET is zero!)
+
+Test_and_set is a more limited version of compare_and_swap. Its only
+advantage is that it is more easily implementable on some hardware. It
+should thus be used if only binary test-and-set functionality is needed.
+
+If available, we also provide compare_and_swap operations that operate
+on wider values. Since standard data types for double width values
+may not be available, these explicitly take pairs of arguments for the
+new and/or old value. Unfortunately, there are two common variants,
+neither of which can easily and efficiently emulate the other.
+The first performs a comparison against the entire value being replaced,
+where the second replaces a double-width replacement, but performs
+a single-width comparison:
+
+int compare_double_and_swap_double(volatile AO_double_t * addr,
+ AO_t old_val1, AO_t old_val2,
+ AO_t new_val1, AO_t new_val2);
+
+int compare_and_swap_double(volatile AO_double_t * addr,
+ AO_t old_val1,
+ AO_t new_val1, AO_t new_val2);
+
+where AO_double_t is a structure containing AO_val1 and AO_val2 fields,
+both of type AO_t. For compare_and_swap_double, we compare against
+the val1 field. AO_double_t exists only if AO_HAVE_double_t
+is defined.
+
+ORDERING CONSTRAINTS:
+
+Each operation name also includes a suffix that specifies the associated
+ordering semantics. The ordering constraint limits reordering of this
+operation with repsect to other atomic operations and ordinary memory
+references. The current implementation assumes that all memory references
+are to ordinary cacheable memory; the ordering guarantee is with respect
+to other threads or processes, not I/O devices. (Whether or not this
+distinction is important is platform-dependent.)
+
+Ordering suffixes are one of the following:
+
+<none>: No memory barrier. A plain AO_nop() really does nothing.
+_release: Earlier operations must become visible to other threads
+ before the atomic operation.
+_acquire: Later operations must become visible after this operation.
+_read: Subsequent reads must become visible after reads included in
+ the atomic operation or preceding it. Rarely useful for clients?
+_write: Earlier writes become visible before writes during or after
+ the atomic operation. Rarely useful for clients?
+_full: Ordered with respect to both earlier and later memops.
+_release_write: Ordered with respect to earlier writes. This is
+ normally implemented as either a _write or _release
+ barrier.
+_dd_acquire_read: Ordered with respect to later reads that are data
+ dependent on this one. This is needed on
+ a pointer read, which is later dereferenced to read a
+ second value, with the expectation that the second
+ read is ordered after the first one. On most architectures,
+ this is equivalent to no barrier.
+_release_read: Ordered with respect to earlier reads. Useful for
+ implementing read locks. Can be implemented as _release,
+ but not as _read, since _read groups the current operation
+ with the earlier ones.
+
+We assume that if a store is data-dependent on an a previous load, then
+the two are always implicitly ordered.
+
+It is possible to test whether AO_<op><barrier> is available on the
+current platform by checking whether AO_HAVE_<op>_<barrier> is defined
+as a macro.
+
+Note that we generally don't implement operations that are either
+meaningless (e.g. AO_nop_acquire, AO_nop_release) or which appear to
+have no clear use (e.g. AO_load_release, AO_store_acquire, AO_load_write,
+AO_store_read). On some platforms (e.g. PA-RISC) many operations
+will remain undefined unless AO_REQUIRE_CAS is defined before including
+the package.
+
+When typed in the package build directory, the following command
+will print operations that are unimplemented on the platform:
+
+make test_atomic; ./test_atomic
+
+The following command generates a file "list_atomic.i" containing the
+macro expansions of all implemented operations on the platform:
+
+make list_atomic.i
+
+Future directions:
+
+We expect the list of memory barrier types to remain more or less fixed.
+However, it is likely that the list of underlying atomic operations will
+grow. It would also be useful to support double-wide and narrower operations
+when available.
+
+Example:
+
+If you want to initialize an object, and then "publish" a pointer to it
+in a global location p, such that other threads reading the new value of
+p are guaranteed to see an initialized object, it suffices to use
+AO_release_write(p, ...) to write the pointer to the object, and to
+retrieve it in other threads with AO_acquire_read(p).
+
+Platform notes:
+
+All X86: We quietly assume 486 or better.
+
+Windows:
+Currently AO_REQUIRE_CAS is not supported.
+
+Microsoft compilers:
+Define AO_ASSUME_WINDOWS98 to get access to hardware compare-and-swap
+functionality. This relies on the InterlockedCompareExchange() function
+which was apparently not supported in Windows95. (There may be a better
+way to get access to this.) Currently only X86(32 bit) is supported for
+Windows.
+
+Gcc on x86:
+Define AO_USE_PENTIUM4_INSTRS to use the Pentium 4 mfence instruction.
+Currently this is appears to be of marginal benefit.
--- /dev/null
+The libatomic_ops_gpl includes a simple almost-lock-free malloc implementation.
+
+This is intended as a safe way to allocate memory from a signal handler,
+or to allocate memory in the context of a library that does not know what
+thread library it will be used with. In either case locking is impossible.
+
+Note that the operations are only guaranteed to be 1-lock-free, i.e. a
+single blocked thread will not prevent progress, but multiple blocked
+threads may. To safely use these operations in a signal handler,
+the handler should be non-reentrant, i.e. it should not be interruptable
+by another handler using these operations. Furthermore use outside
+of signal handlers in a multithreaded application should be protected
+by a lock, so that at most one invocation may be interrupted by a signal.
+The header will define the macro "AO_MALLOC_IS_LOCK_FREE" on platforms
+on which malloc is completely lock-free, and hence these restrictions
+do not apply.
+
+In the presence of threads, but absence of contention, the time performance
+of this package should be as good, or slightly better than, most system
+malloc implementations. Its space performance
+is theoretically optimal (to within a constant factor), but probably
+quite poor in practice. In particular, no attempt is made to
+coalesce free small memory blocks. Something like Doug Lea's malloc is
+likely to use significantly less memory for complex applications.
+
+Perfomance on platforms without an efficient compare-and-swap implementation
+will be poor.
+
+This package was not designed for processor-scalability in the face of
+high allocation rates. If all threads happen to allocate different-sized
+objects, you might get lucky. Otherwise expect contention and false-sharing
+problems. If this is an issue, something like Maged Michael's algorithm
+(PLDI 2004) would be technically a far better choice. If you are concerned
+only with scalablity, and not signal-safety, you might also consider
+using Hoard instead. We have seen a factor of 3 to 4 slowdown from the
+standard glibc malloc implementation with contention, even when the
+performance without contention was faster. (To make the implementation
+more scalable, one would need to replicate at least the free list headers,
+so that concurrent access is possible without cache conflicts.)
+
+Unfortunately there is no portable async-signal-safe way to obtain large
+chunks of memory from the OS. Based on reading of the source code,
+mmap-based allocation appears safe under Linux, and probably BSD variants.
+It is probably unsafe for operating systems built on Mach, such as
+Apple's Darwin. Without use of mmap, the allocator is
+limited to a fixed size, statically preallocated heap (2MB by default),
+and will fail to allocate objects above a certain size (just under 64K
+by default). Use of mmap to circumvent these limitations requires an
+explicit call.
+
+The entire interface to the AO_malloc package currently consists of:
+
+#include <atomic_ops_malloc.h> /* includes atomic_ops.h */
+
+void *AO_malloc(size_t sz);
+void AO_free(void *p);
+void AO_malloc_enable_mmap(void);
--- /dev/null
+Note that the AO_stack implementation is licensed under the GPL,
+unlike the lower level routines.
+
+The header file atomic_ops_stack.h defines a linked stack abstraction.
+Stacks may be accessed by multiple concurrent threads. The implementation
+is 1-lock-free, i.e. it will continue to make progress if at most one
+thread becomes inactive while operating on the data structure.
+
+(The implementation can be built to be N-lock-free for any given N. But that
+seems to rarely be useful, especially since larger N involve some slowdown.)
+
+This makes it safe to access these data structures from non-reentrant
+signal handlers, provided at most one non-signal-handler thread is
+accessing the data structure at once. This latter condition can be
+ensured by acquiring an ordinary lock around the non-hndler accesses
+to the data structure.
+
+For details see:
+
+Hans-J. Boehm, "An Almost Non-Blocking Stack", PODC 2004,
+http://portal.acm.org/citation.cfm?doid=1011767.1011774, or
+http://www.hpl.hp.com/techreports/2004/HPL-2004-105.html
+(This is not exactly the implementation described there, since the
+interface was cleaned up in the interim. But it should perform
+very similarly.)
+
+We use a fully lock-free implementation when the underlying hardware
+makes that less expensive, i.e. when we have a double-wide compare-and-swap
+operation available. (The fully lock-free implementation uses an AO_t-
+sized version count, and assumes it does not wrap during the time any
+given operation is active. This seems reasonably safe on 32-bit hardware,
+and very safe on 64-bit hardware.) If a fully lock-free implementation
+is used, the macro AO_STACK_IS_LOCK_FREE will be defined.
+
+The implementation is interesting only because it allows reuse of
+existing nodes. This is necessary, for example, to implement a memory
+allocator.
+
+Since we want to leave the precise stack node type up to the client,
+we insist only that each stack node contains a link field of type AO_t.
+When a new node is pushed on the stack, the push operation expects to be
+passed the pointer to this link field, which will then be overwritten by
+this link field. Similarly, the pop operation returns a pointer to the
+link field of the object that previously was on the top of the stack.
+
+The cleanest way to use these routines is probably to define the stack node
+type with an initial AO_t link field, so that the conversion between the
+link-field pointer and the stack element pointer is just a compile-time
+cast. But other possibilities exist. (This would be cleaner in C++ with
+templates.)
+
+A stack is represented by an AO_stack_t structure. (This is normally
+2 or 3 times the size of a pointer.) It may be statically initialized
+by setting it to AO_STACK_INITIALIZER, or dynamically initialized to
+an empty stack with AO_stack_init. There are only three operations for
+accessing stacks:
+
+void AO_stack_init(AO_stack_t *list);
+void AO_stack_push_release(AO_stack_t *list, AO_t *new_element);
+AO_t * AO_stack_pop_acquire(volatile AO_stack_t *list);
+
+We require that the objects pushed as list elements remain addressable
+as long as any push or pop operation are in progress. (It is OK for an object
+to be "pop"ped off a stack and "deallocated" with a concurrent "pop" on
+the same stack still in progress, but only if "deallocation" leaves the
+object addressable. The second "pop" may still read the object, but
+the value it reads will not matter.)
+
+We require that the headers (AO_stack objects) remain allocated and
+valid as long as any operations on them are still in-flight.
+
+We also provide macros AO_REAL_HEAD_PTR that converts an AO_stack_t
+to a pointer to the link field in the next element, and AO_REAL_NEXT_PTR
+that converts a link field to a real, dereferencable, pointer to the link field
+in the next element. This is intended only for debugging, or to traverse
+the list after modification has ceased. There is otherwise no guarantee that
+walking a stack using this macro will produce any kind of consistent
+picture of the data structure.
--- /dev/null
+Most of the atomic_ops functionality is available under Win32 with
+the Microsoft tools, but the build process currently is considerably more
+primitive than on Linux/Unix platforms.
+
+To build:
+
+1) Go to the src directory in the distribution.
+2) Make sure the Microsoft command-line tools (e.g. nmake) are available.
+3) Run "nmake -f Makefile.msft". This should run some tests, which
+may print warnings about the types of the "Interlocked" functions.
+I haven't been able to make all versions of VC++ happy. If you know
+how to, please send a patch.
+4) To compile applications, you will need to retain or copy the following
+pieces from the resulting src directory contents:
+ "atomic_ops.h" - Header file defining low-level primitives. This
+ includes files from:
+ "atomic_ops"- Subdirectory containing implementation header files.
+ "atomic_ops_stack.h" - Header file describing almost lock-free stack.
+ "atomic_ops_malloc.h" - Header file describing almost lock-free malloc.
+ "libatomic_ops_gpl.lib" - Library containing implementation of the
+ above two. The atomic_ops.h implementation
+ is entirely in the header files in Win32.
+
+Most clients of atomic_ops.h will need to define AO_ASSUME_WINDOWS98 before
+including it. Compare_and_swap is otherwise not available.
+
+Note that the library is covered by the GNU General Public License, while
+the top 2 of these pieces allow use in proprietary code.
