--- Comment #10 from niXman <i.nixman at autistici dot org> ---
yes, fixed for the `master`.

```
foo:
.LFB6604:
        .cfi_startproc
        movdqu  (%rdi), %xmm1
        movdqa  .LC0(%rip), %xmm0
        pcmpgtb %xmm1, %xmm0
        ret
        .cfi_endproc
.LFE6604:
```

can it be applied at least for gcc-12 branch ?
