--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a better testcase which shows the issue all the way back to at least
4.4.7:
typedef short __attribute__((__vector_size__(16))) V;

long double t1;

void
foo(void)
{
  V t={1024>>1, 0, 0, 0, 32768>>1};
  long double tt = *(long double*)&t;
  t1 /= tt;
}
