[Bug target/42869] GOMP_critical_start wrong on Itanium due to __sync miscompilation

[jakub at gcc dot gnu dot org]

------- Comment #3 from jakub at gcc dot gnu dot org  2010-03-09 23:33 -------
__sync_bool_compare_and_swap is documented to be a full barrier, so I think the
bug must be on the ia64/sync.md side.
