--- Comment #39 from Andrew Pinski <pinskia at gcc dot gnu.org> 2012-11-02 02:41:37 UTC --- (In reply to comment #38) > Ah, the #c3 fail on powerpc was due to a powerpc glibc pthread_once bug. And > comment #36 should have read: > ..previous test was for *either* atomic bool or atomic int. Looks like the MIPS glibc pthread_once has the same issue too. I should have read the comments fully to see that.
