--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #5) > Ugh, slp creates here V1QImode vectors? Why? That can't be ever faster > than just scalar QImode, no? We do not reject single-lane vectors iff the target happily supports them. It definitely would have avoided some bugs if we did - but it's also good we fix those.
