--- Comment #2 from Richard Henderson <rth at gcc dot gnu.org> 2011-10-10 16:51:19 UTC --- (In reply to comment #1) > Git bisect points to Rev179701: ... > Rename vshuffle/vec_shuffle to vec_perm. > > * doc/extend.texi (__builtin_shuffle): Improve the description to > include the modulus of the selector. Mention OpenCL. > * doc/md.texi (vec_perm, vec_perm_const): Document named patterns. Are you sure about those bisect results? I admit that md.texi did have a typo that broke "make pdf", but I cannot imagine this code being involved in a bootstrap at all, much less affecting profiledbootstrap.
