--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
So it seems the target can handle the vector code as written but cannot handle
the requested simplification.

It works fine on x86_64 even with AVX512 which also uses similar masks.

So it looks like missed MVE patterns.

Confirmed.
