--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a better testcase which fails even at -O1 and does not depend on the
vectorizer:
```
typedef int v4si __attribute__ ((vector_size (4*sizeof(int))));
typedef short v4hi __attribute__ ((vector_size (4*sizeof(short))));

v4hi f(v4hi a, v4hi b)
{
        auto t =3D __builtin_convertvector (a, v4si);
        auto t1 =3D __builtin_convertvector (b, v4si);
        t ^=3D t1;
        return __builtin_convertvector (t, v4hi);
}
```=
