--- Comment #8 from GCC 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:c81543b3379fa11742d2178b87edbf1e72799d61 commit r15-7020-gc81543b3379fa11742d2178b87edbf1e72799d61 Author: Richard Biener <rguent...@suse.de> Date: Fri Jan 17 15:41:19 2025 +0100 tree-optimization/118529 - ICE with condition vectorization On sparc we end up choosing vector(8) <signed-boolean:1> for the condition but vector(2) int for the value of a COND_EXPR but we fail to verify their shapes match and thus things go downhill. This is a missed-optimization on the pattern recognition side as well as unhandled vector decomposition in vectorizable_condition. The following plugs just the observed ICE for now. PR tree-optimization/118529 * tree-vect-stmts.cc (vectorizable_condition): Check the shape of the vector and condition vector type are compatible. * gcc.target/sparc/pr118529.c: New testcase.
