The following patch optimizes that by using the right iterator on those 4 patterns. 2021-04-27 Jakub Jelinek <ja...@redhat.com> PR target/99405 * config/i386/i386.md (*<insn><mode>3_mask, *<insn><mode>3_mask_1): For any_rotate define_insn_split and following splitters, use SWI iterator instead of SWI48. * gcc.target/i386/pr99405.c: New test.
