--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Vector testcases too:
```
#define vector __attribute__((vector_size(4*sizeof(int))))

vector int
signed_f1(vector int v)
{
  vector int b_5;
  vector int _7;
  vector int _9;

  b_5 =3D v>>(sizeof(int)*8 - 1);
  _9 =3D b_5 | 1;
  _7 =3D v * _9;
  return _7;
}

vector unsigned
unsigned_f1 (vector int v)
{
  vector unsigned int d_6;
  vector int b_5;
  vector unsigned int v1_2;
  vector unsigned int _7;
  vector int _9;

  b_5 =3D v>>(sizeof(int)*8 - 1);
  _9 =3D b_5 | 1;
  d_6 =3D (vector unsigned int) _9;
  v1_2 =3D (vector unsigned int) v;
  _7 =3D v1_2 * d_6;
  return _7;
}

```

Which does work with the match pattern in comment #5.=
