--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:04b4f3152593f85b05974528d1607619dd77d702 commit r12-2876-g04b4f3152593f85b05974528d1607619dd77d702 Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Aug 12 11:26:57 2021 +0200 i386: Fix up V32HImode permutations with -mno-avx512bw [PR101860] My patch from yesterday apparently broke some V32HImode permutations as the testcase shows. The first function assumed it would never be called in d->testing_p mode and so went right away into emitting the code. And the second one assumed V32HImode would never reach it, which now can for the !TARGET_AVX512BW case. We don't have a instruction in that case though. 2021-08-12 Jakub Jelinek <ja...@redhat.com> PR target/101860 * config/i386/i386-expand.c (ix86_expand_vec_one_operand_perm_avx512): If d->testing_p, return true after performing checks instead of actually expanding the insn. (expand_vec_perm_broadcast_1): Handle V32HImode - assert !TARGET_AVX512BW and return false. * gcc.target/i386/avx512f-pr101860.c: New test.
