--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
New testcase which shows this is indepdent of VRP, fails in GCC 12.x also:
```
static int t;

int f (int a)
{
  int t1;
  asm (" " : "=3Dr" (t1) : : "eax", "memory");
  t =3D t1;
  if (a)
    return 0;
  __builtin_unreachable();
}
```=
