--- Comment #11 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:ffb092784fc2513c2944253efc57c27de068c8b9 commit r11-10737-gffb092784fc2513c2944253efc57c27de068c8b9 Author: Richard Biener <rguent...@suse.de> Date: Wed May 3 11:06:28 2023 +0200 tree-optimization/109473 - fix type mismatch in reduction vectorization When backporting the PR109473 fix I failed to realize its testcase will run into an unrelated similar bug. With GCC 12 the code has seen substantial refactoring so the following applies a local fix to make sure we are using the correct types when building initial values for reductions. PR tree-optimization/109473 * tree-vect-loop.c (get_initial_def_for_reduction): Convert the scalar values to the vector component type before using it to build the vector for the initial value.
