--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Andre Simoes Dias Vieira <avie...@gcc.gnu.org>: https://gcc.gnu.org/g:8b704ed0b8f35ec1a57e70bd8e6913ba0e9d1f24 commit r14-4765-g8b704ed0b8f35ec1a57e70bd8e6913ba0e9d1f24 Author: Andre Vieira <andre.simoesdiasvie...@arm.com> Date: Thu Oct 19 18:28:12 2023 +0100 vect: don't allow fully masked loops with non-masked simd clones [PR 110485] When analyzing a loop and choosing a simdclone to use it is possible to choose a simdclone that cannot be used 'inbranch' for a loop that can use partial vectors. This may lead to the vectorizer deciding to use partial vectors which are not supported for notinbranch simd clones. This patch fixes that by disabling the use of partial vectors once a notinbranch simd clone has been selected. gcc/ChangeLog: PR tree-optimization/110485 * tree-vect-stmts.cc (vectorizable_simd_clone_call): Disable partial vectors usage if a notinbranch simdclone has been selected. gcc/testsuite/ChangeLog: * gcc.dg/gomp/pr110485.c: New test.
