--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> --- Created attachment 32736 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32736&action=edit hack patch that does the job (but has wrong-code issues, so I need to add a new hook to walk_non_aliased_vuses instead). _88 = 1; you might want to check whether that improves things and point me to stuff that is left (FRE related).
