--- Comment #11 from Richard Biener <rguenth at gcc dot gnu.org> --- Created attachment 46880 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=46880&action=edit prototype This improves code-gen to use pextrw where possible but that doesn't make any measurable difference on runtime. Maybe the example loop isn't representative or the improvement isn't big enough.
