--- Comment #16 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to David Edelsohn from comment #15) > Another option is to force the COMDAT group to NULL in set_comdat_group() if > !HAVE_COMDAT_GROUP. That would allow the rest of the COMDAT functionality to > continue to work. Does that make any sense to try? Not really -- setting the comdat group is the only thing set_comdat_group does. So what do the FAILs look like? They ICE with the new assert? What is the other caller(s) that call set_comdat_group with a non-NULL group besides make_decl_one_only?
