--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 34779 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=34779&action=edit gcc5-pr64963.patch Updated untested patch (well, tested with dg.exp=ipa/* ipa.exp so far), whcih doesn't introduce these regressions and I think roughly matches what we used to do with DECL_SECTION_NAME in the past. Another thing is DECL_COMDAT_GROUP, seems we used to copy that and only clear in some cases (non-local ones).
