--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> 2011-11-22 03:44:39 UTC --- Created attachment 25877 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25877 Patch which improves the use of clobbers for toplevel BIND expressions. Though at -O0 we should not emit the clobbers at all. That can be cured by adding !optimize to the condition which includes !top_level.
