--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The powerpc issue was fixed in GCC 13 (most likely by
r13-220-g067fe66c8ba9b16feacf66fce9ae668091e42821 ).

s390 most likely needs the same treatment:
```

```

I cannot test this at all, and a similar testcase in PR 101168 should be ad=
ded
for s390.=
