--- Comment #3 from GCC 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:a3ff76278efe006dc0b50249c8e5baf565bff56b commit r14-6752-ga3ff76278efe006dc0b50249c8e5baf565bff56b Author: Andre Vieira <andre.simoesdiasvie...@arm.com> Date: Wed Dec 20 16:41:52 2023 +0000 veclower: improve selection of vector mode when lowering [PR 112787] This patch addresses the issue reported in PR target/112787 by improving the compute type selection. We do this by not considering types with more elements than the type we are lowering since we'd reject such types anyway. gcc/ChangeLog: PR target/112787 * tree-vect-generic.cc (type_for_widest_vector_mode): Change function to use original vector type and check widest vector mode has at most the same number of elements. (get_compute_type): Pass original vector type rather than the element type to type_for_widest_vector_mode and remove now obsolete check for the number of elements. gcc/testsuite/ChangeLog: * gcc.target/aarch64/pr112787.c: New test.
