--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Ok, but please also during expansion try to detect the all ones mask case and already during expansion emit normal non-masked load (+ we need a define_insn_and_split for it with pre-reload splitting just in case it gets propagated in combine).
