[Bug libgomp/45025] Memory ordering issues with libgomp critical sections and __sync

[jakub at gcc dot gnu dot org]

------- Comment #2 from jakub at gcc dot gnu dot org  2010-07-22 07:59 -------
So, 1. is fixed.  If __sync_*compare_and_swap on PowerPC doesn't act as full
barrier, that would be a target bug, not libgomp bug.

Unless separate __sync_*_acq/__sync_*_rel builtins are added, I'm afraid the
only option for libgomp would be on the weakly ordered targets to use inline
asm instead, which wouldn't be very pretty.
