--- Comment #1 from sudi at gcc dot gnu.org ---
Ah I think I need a better effective target check. This test would only pass
for target that have a vector/scalar shift/rotate optab.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92870
--- Comment #2 from sudi at gcc dot gnu.org ---
So I am sure how to get a list of targets that would support a particular
optab. I guess I can introduce a new effective target check with only the
targets that I know pass? Would that be ok?

Haven't looked very closely to PR82564 but it was marked as a possible
duplicate to an already resolved ticket a year ago. In any case I can confirm
this failure is still occurring for aarch64
