--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-01-31 11:36:24 UTC --- Created attachment 23177 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23177 gcc46-pr47538.patch The #c8 patch doesn't bootstrap, agree with Richard this is not stage4ish. Another alternative patch, which just reverts the patch that caused it and limits it to comparisons (where lhs type is always unrelated to the comparison type).
