--- Comment #24 from Jason Merrill <jason at gcc dot gnu.org> 2013-01-16 15:53:28 UTC --- (In reply to comment #23) > Merging of target attribute is what gcc/g++ did though, the function would get > then both target attributes (seems later decl's target wins), and the first > target attribute in DECL_ATTRIBUTES would be the one to be used. This seems like broken behavior that we don't need to preserve, in which case my suggestion in comment #8 could work.
