--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 51278 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51278&action=edit gcc12-pr80355-2.patch And this incremental patch makes it handle even similar V32HImode/V64QImode permutations with -mavx512f -mno-avx512bw.
