--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:b789c44c6463452900f7b1e6d2a0af6567534bfc commit r12-8054-gb789c44c6463452900f7b1e6d2a0af6567534bfc Author: Richard Biener <rguent...@suse.de> Date: Wed Apr 6 11:18:12 2022 +0200 tree-optimization/105175 - avoid -Wvector-operation-performance This avoids -Wvector-operation-performance diagnostics for vectorizer produced code. It's unfortunate the warning_at code in tree-vect-generic.cc needs adjustments but the diagnostic suppression code doesn't magically suppress those otherwise. 2022-04-06 Richard Biener <rguent...@suse.de> PR tree-optimization/105175 * tree-vect-stmts.cc (vectorizable_operation): Suppress -Wvector-operation-performance if using emulated vectors. * tree-vect-generic.cc (expand_vector_piecewise): Do not diagnose -Wvector-operation-performance when suppressed. (expand_vector_parallel): Likewise. (expand_vector_comparison): Likewise. (expand_vector_condition): Likewise. (lower_vec_perm): Likewise. (expand_vector_conversion): Likewise. * gcc.dg/pr105175.c: New testcase.
