--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
/* See PR63679, if the target forces the initializer to memory then
   DOM is not able to perform this optimization.  */

So most likely this should be xfailed for powerpc.  Not a regression because
this testcase is a new one.

--- 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.

Also FAILs on Solaris/SPARC, in the same way as on powerpc.

This is confirmed.  Do we have agreement to XFAIL the testcase on powerpc and
sparc?

Looks like aarch64*-*-* needs to be added also.  I will look into that next
week.

I see this test failing on arm too.
Should it be xfailed there as well?
