--- Comment #4 from Tomasz Kamiński <tkaminsk at gcc dot gnu.org> ---
I have backported the test to GCC-13, so the failure will not occur for GCC-12
for obvious reason. I will double check if the test would fail if on 12 branch.

If so, I think I will simply remove the test case. The #pragma seem to be
sufficient to silence warnings for major architecture, so the change is useful
by itself. This way I will avoid breaking (unknown) list of targets, for which
it does not help.
