--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
It's already xfailed for hppa, so yes, likely (if you can verify the theory).
Note that there may be other reasons, like vectorizing using stmts that
we don't constant-fold or the inability to unroll the loop due to target
specific limits.

Needs investigation.

It's still a testsuite regression.
