--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a "valid" x86_64 testcase:

```
typedef float __attribute__ ((vector_size (64))) vec;
register vec a asm("zmm2"), b asm("zmm0"), c asm("zmm1");

void
test (void)
{
  for (int i =3D 0; i < 8; i++)
    c[i] =3D a[i] < b[i] ? 0.1 : 0.2;
}
```
Which fails with `-O2  -g0 -mavx512f` which started in GCC 4.9 when -mavx51=
2f
support was added.=
