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.
