--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
We need to guard the patterns.  Handling V1 modes in the expanders is possible
but it doesn't fix the root cause (there's also vector-by-scalar shifts).

Maybe we should define/document a set of arithmetics we assume available
for all vector modes (including bitwise and) and make this one a target bug?
