--- Comment #17 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-01-14 18:32:44 UTC --- Actually, what you'd merge is everything as usually if mv attribute isn't on either of the decls, or if mv attribute is present on either one, and both decls have either the same target attribute, or no target attribute at all. If mv attribute is on newdecl or olddecl, and target attribute is either present on just one of the decls, or on both, but with different argument, it would treat them as decls that mangle differently and won't be merged.
