--- Comment #15 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Eric Botcazou <ebotca...@gcc.gnu.org>: https://gcc.gnu.org/g:6f2bb57f909014618aaf770bfaaf49e28e410311 commit r12-9324-g6f2bb57f909014618aaf770bfaaf49e28e410311 Author: Eric Botcazou <ebotca...@adacore.com> Date: Tue Mar 28 10:13:24 2023 +0200 Fix PR target/109140 This is a regression present on the mainline and 12 branch at -O2, but the issue is related to vectorization so was present at -O3 in earlier versions. The vcondu expander that was added for VIS 3 more than a decade ago does not fully work, because it does not filter out the unsigned condition codes (the instruction is an UNSPEC that accepts only signed condition codes). While I was at it, I also added the missing vcond and vcondu expanders for the new comparison instructions that were added in VIS 4. gcc/ PR target/109140 * config/sparc/sparc.cc (sparc_expand_vcond): Call signed_condition on operand #3 to get the final condition code. Use std::swap. * config/sparc/sparc.md (vcondv8qiv8qi): New VIS 4 expander. (fucmp<gcond:code>8<P:mode>_vis): Move around. (fpcmpu<gcond:code><GCM:gcm_name><P:mode>_vis): Likewise. (vcondu<GCM:mode><GCM:mode>): New VIS 4 expander. gcc/testsuite/ * gcc.target/sparc/20230328-1.c: New test. * gcc.target/sparc/20230328-2.c: Likewise. * gcc.target/sparc/20230328-3.c: Likewise. * gcc.target/sparc/20230328-4.c: Likewise.
