--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:a73b65b74105e76473cc2825bb4e7253deaf18b3 commit r14-2338-ga73b65b74105e76473cc2825bb4e7253deaf18b3 Author: Andrew Pinski <apin...@marvell.com> Date: Tue Jul 4 20:38:06 2023 -0700 Fix PR 110554: vec lowering introduces scalar signed-boolean:32 comparisons So the problem is vector generic decided to do comparisons in signed-boolean:32 types but the rest of the middle-end was not ready for that. Since we are building the comparison which will feed into a cond_expr here, using boolean_type_node is better and also correct. The rest of the compiler thinks the ranges for comparison is always [0,1] too. Note this code does not currently lowers bigger vector sizes into smaller vector sizes so using boolean_type_node here is better. OK? bootstrapped and tested on x86_64-linux-gnu with no regressions. gcc/ChangeLog: PR middle-end/110554 * tree-vect-generic.cc (expand_vector_condition): For comparisons, just build using boolean_type_node instead of the cond_type. For non-comparisons/non-scalar-bitmask, build a ` != 0` gimple that will feed into the COND_EXPR.
