------- Comment #3 from rth at gcc dot gnu dot org 2005-10-17 21:02 ------- If we decided this was not-a-bug, then there's a bug in __sync_synchronize, as that uses asm("") if there's no target fallback.
But personally I think this is a documentation bug. We should consider memory to be clobbered in old-style asms. Your pointer to the old PR is irrelevant; that was a new-style asm. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24414
