--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
x86_64 Testcase (which invokes undefined behavior) which has been failing since
at least 4.9.1 even:
```
typedef double __attribute__ ((vector_size (16))) vec;
register vec a asm("ymm2"), b asm("ymm0"), c asm("ymm1");

void
test (void)
{
  for (int i = 0; i < 4; i++)
    c[i] = a[i] < b[i] ? 0.1 : 0.2;
}
```
