--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think at least x86 doesn't currently have instructions which would support
both, CCing Hongtao to verify that, but not sure if e.g. RISC-V won't have
something eventually for both. Don't we need to check the mode also somewhere
in the vectorizer (so that we don't happily try to vectorize using it only to
get it lowered later to scalar ops during generic vector lowering (or
forwprop?)?
