Individual Change Summary By Developer:
Dave Goodell (17):

AC_LANG_SOURCE" warnings

coverage" happy

* [svn-r137] improve opa_queue.h comments
* [svn-r138] add read barrier to opa_queue.h
* [svn-r140] build-sys: fixes for automake-1.12 compatibility
* [svn-r142] pkg-config: unconditionally add -lopa to Libs
* [svn-r147] Revert r145: "Since we now depend on automake-1.12.3
[...]"

* [svn-r152] fix incorrect PPC LL/SC comment
* add .gitignore file
* bump version number to 1.0.4 for a new release
Kazutomo Yoshii (1):
* [svn-r151] added preliminary ARM support. only tested it on panda
board(ARMv7) and gcc 4.6.3
Neil Fortner (3):
* [svn-r136] Fix problem in queue that manifested in an occasional
infinite loop on POWER7 machines. Added a write barrier to
OPA_Queue_enqueue() after the invocation of OPA_SHM_SET_REL_NULL to
prevent the "next" pointer from being set to NULL after the element
was enqueued (and possibly modified by another thread).
* [svn-r139] Add memory barriers to LL/SC ABA tests. Should fix
occasional failure on POWER7 systems.
* Add more memory barriers to LL/SC ABA tests. This should fix the
recent errors on POWER7.
Pavan Balaji (9):
* [svn-r127] Some x86 processors don't seem to like sfence either.
Making the write barrier even more stringent by forcing it to do a
full barrier.
* [svn-r128] Forgot to update the comment when we fixed the sfence
problem in r127.
* [svn-r135] configure.in --> configure.ac to match the naming
convention of newer autotools.
* [svn-r143] Propagate autoreconf errors upstream.
* [svn-r144] Remove internally maintained pgcc patch since
automake-1.12.3 fixes this.
* [svn-r145] Since we now depend on automake-1.12.3, we no longer need
to check if AM_PROG_AR is available.
* [svn-r146] svn:ignore.
* [svn-r148] svn:ignores.
* [svn-r150] IBM-contributed patch: Added support for non-versioned
libraries
William Gropp (1):
* [svn-r141] Added missing svn:ignore entries
=============
OpenPA v1.0.3

* pkg-config support
* Emulated atomics can now be detected by the presence of an OPA_EXPLICIT_EMULATION #define in opa_config.h.
* PPC types are now correctly aligned to 8 bytes instead of 16 bytes.
* many more tests for "make check", fixed missing memory barriers in one test
