--- Comment #18 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Andreas Schwab from comment #17) > FAIL -> UNSUPPORTED That is expected on targets that don't provide compute_vecsize_and_simdlen target hook. If it is a target with reasonable vector support (not really counting here ia64 or alpha, but e.g. powerpc*, s390*, aarch64, arm etc. should), then declare simd is not creating any simd clones. I'll commit the change.
