--- Comment #15 from Marc Glisse <glisse at gcc dot gnu.org> ---
Oups, sorry, or_ps may be harder, because representing it with vector
extensions requires casts to integer vectors, which makes it much harder to
actually generate or_ps in the backend (there is at least one PR about that),
so we probably won't do it soon.
