--- Comment #12 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a testcase which shows the wrong code which was mentioned during the
review:
```
static int t;

int f (int *a)
{
  int t1, t2 =3D 0;
  asm ("shouldshowupstill %1" : "=3Dr" (t1), "=3Dm"(t2) : : );
  t =3D t1;
  return t2;
}
```=
