--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-06-25 08:48:50 UTC --- Created attachment 27699 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27699 gcc48-pr53759.patch Sounds like an obvious typo in that change, the x, x, x alternative is already earlier and shouldn't use vmovlps insn, so that obviously should have been x, m, x.
