--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> --- Created attachment 42620 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42620&action=edit patch Otherwise untested patch. Note ivdep is mapped to safelen which isn't useful for parallelization given safelen perserves forward dependences.
