--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Eric Botcazou <ebotca...@gcc.gnu.org>: https://gcc.gnu.org/g:ab952929f7741998e3f28959c85e7abbf88ea79f commit r15-5632-gab952929f7741998e3f28959c85e7abbf88ea79f Author: Eric Botcazou <ebotca...@adacore.com> Date: Sun Nov 24 20:23:34 2024 +0100 Fix vectorization regressions on the SPARC This fixes the vectorization regressions present on the SPARC by switching from vcond[u] patterns to vec_cmp[u] + vcond_mask_ patterns. While I was at it, I merged the patterns for V4HI/V2SI and V8QI enabled with VIS 3/VIS 4 to follow the model of those enabled with VIS 4B, and standardized all the mnemonics to the version documented in the Oracle SPARC architecture 2015. gcc/ PR target/117715 * config/sparc/sparc-protos.h (sparc_expand_vcond): Rename to...
