* Updates to make non-inline assembly behave properly on AIX. This commit was SVN r4364. 2005-02-10 00:06:54 +00:00			`START_FILE`
* Update build system to support non-GCC inline assembly, including detection of assembler format * Fix minor bugs in AMD64, PPC, and IA32 assembly for atomic operations * Clean up the #defines to look for when examining level of atomic operation support This commit was SVN r4183. 2005-01-27 01:39:55 +00:00			`TEXT`

* sync opal_atomic_cmpset_{32,64} for AMD64 with the x86 32 bit version, as I understand how that one works and don't really understand what was in the amd64 code (which was copied from before I started working on the inline assembly). This fixes the race condition we were seeing on PGI causing test failures * sync non-inline assembly with inline assembly version This needs to go to the v1.0 branch This commit was SVN r9539. 2006-04-06 01:23:33 +00:00			`movl %esi, %eax`
