--- Comment #1 from Drea Pinski <pinskia at gcc dot gnu.org> ---
Also missing it setting it for REF_REVERSE_STORAGE_ORDER:
```
int f2(void *a, bool b, bool bb)
{
  if (b)
  {
    union U1 t = *((union U1*)a);
    if (bb)
      return t.i[0];
    return t.s.a;
  }
  {
    union U1 t = *((union U1*)a);
    if (bb)
      return t.i[0];
    return t.s.a;
  }
}
```
