--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <[email protected]>: https://gcc.gnu.org/g:793da440da5c84090af9e864b824157db02cdc82 commit r17-1389-g793da440da5c84090af9e864b824157db02cdc82 Author: Jakub Jelinek <[email protected]> Date: Sat Jun 6 09:50:35 2026 +0200 i386: Fix up predicates on <ssse3_avx2>_pmulhrsw<mode>3, smulhrs<mode>3 expanders [PR125611] The following testcase ICEs since r6-6060-gacf93f1edc9 aka PR68991 fix. THe problem is that the commit has changed the predicates on *<ssse3_avx2>_pmulhrsw<mode>3<mask_name> pattern from nonimmediate_operand to vector_operand but kept the old predicates on the corresponding expanders. With TARGET_AVX that makes no difference (so I've left the <ssse3_avx2>_pmulhrsw<mode>3_mask expander as is, that is only TARGET_AVX512BW && TARGET_AVX512VL), but without it if there is unaligned memory the expander can just expand it as memory without forcing into REG while the pattern will not match. 2026-06-06 Jakub Jelinek <[email protected]> PR target/125611 * config/i386/sse.md (<ssse3_avx2>_pmulhrsw<mode>3, smulhrs<mode>3): Use vector_operand instead of nonimmediate_operand. * gcc.target/i386/ssse3-pr125611.c: New test.
