--- Comment #41 from Andrew Pinski <pinskia at gcc dot gnu.org> 2011-12-01 22:30:26 UTC --- (In reply to comment #40) > OK, sounds good. I'll take this one. Interesting Jeff Law posted a different patch to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45685 which will also fix this issue but that one only handles constants. Though it handles slightly more than just redundant constant PHIs.
