--- Comment #25 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jan Hubicka <hubi...@gcc.gnu.org>: https://gcc.gnu.org/g:9075b0f19eece7d5ddf948204507b5dae9d292c4 commit r12-9400-g9075b0f19eece7d5ddf948204507b5dae9d292c4 Author: Jan Hubicka <j...@suse.cz> Date: Fri Apr 14 19:18:24 2023 +0200 Disable X86_TUNE_AVX256_MOVE_BY_PIECES and STORE_BY_PIECES for znver1-3 I have enabled SSE moves for znver1-3 since they are performance win on this machine too (we avoid using loops or string operations which are more costy). However as discussed in the PR log, this triggers bug in IRA and it was decided it is better to not backport the fix. gcc/ChangeLog: 2023-04-14 Jan Hubicka <hubi...@ucw.cz> PR target/109137 * config/i386/x86-tune.def (X86_TUNE_AVX256_MOVE_BY_PIECES): Remove znver1-3. (X86_TUNE_AVX256_STORE_BY_PIECES): Remove znver1-3.
