--- Comment #28 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Uros Bizjak <u...@gcc.gnu.org>: https://gcc.gnu.org/g:74e8cc28eda9b1d75588fcd4017a735911b9d2b4 commit r14-9346-g74e8cc28eda9b1d75588fcd4017a735911b9d2b4 Author: Uros Bizjak <ubiz...@gmail.com> Date: Wed Mar 6 20:53:50 2024 +0100 i386: Fix and improve insn constraint for V2QI arithmetic/shift insns optimize_function_for_size_p predicate is not stable during optab selection, because it also depends on node->count/node->frequency of the current function, which are updated during IPA, so they may change between early opts and late opts. Use optimize_size instead - optimize_size implies optimize_function_for_size_p (cfun), so if a named pattern uses "&& optimize_size" and the insn it splits into uses optimize_function_for_size_p (cfun), it shouldn't fail. PR target/114232 gcc/ChangeLog: * config/i386/mmx.md (negv2qi2): Enable for optimize_size instead of optimize_function_for_size_p. Explictily enable for TARGET_SSE2. (negv2qi SSE reg splitter): Enable for TARGET_SSE2 only. (<plusminus:insn>v2qi3): Enable for optimize_size instead of optimize_function_for_size_p. Explictily enable for TARGET_SSE2. (<plusminus:insn>v2qi SSE reg splitter): Enable for TARGET_SSE2 only. (<any_shift:insn>v2qi3): Enable for optimize_size instead of optimize_function_for_size_p.
