--- Comment #6 from Segher Boessenkool <segher at gcc dot gnu.org> --- Author: segher Date: Wed May 31 20:58:59 2017 New Revision: 248763 URL: https://gcc.gnu.org/viewcvs?rev=248763&root=gcc&view=rev Log: rs6000: Don't write "nor" as (not (ior () ())) (PR80618) The canonical RTL for "nor" is (and (not ()) (not ())), and that is indeed what we use in boolccv2df3_internal1. So, the splitter for *vector_uneq<mode> should use that form, not (not (ior () ())), which does not match any pattern. PR target/80618 * config/rs6000/rs6000.md (*vector_uneq<mode>): Write the nor in the splitter result in the canonical way. Modified: trunk/gcc/ChangeLog trunk/gcc/config/rs6000/vector.md
