--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a reduced testcase that does not need -mno-sse or any other option but
fails everywhere:
```
typedef unsigned __attribute__((__vector_size__ (1*sizeof(unsigned)))) V;

V v;
unsigned char c;

int
main (void)
{
  V x = (v > 0) > (v != c);
  volatile signed int t = x[0];
  if (t)
    __builtin_abort ();
  return 0;
}
```

t in this case is -2
