--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> ---
And for a condition:

typedef double aligned_double __attribute__((aligned(2*sizeof(double))));
void __attribute__((noipa))
bar (int aligned, double *p)
{
  if (aligned)
    {
      *(aligned_double *)p =3D 3.;
      p[1] =3D 4.;
    }
  else
    {
      p[2] =3D 0.;
      p[3] =3D 1.;
    }
}
double x[8] __attribute__((aligned(2*sizeof (double))));
int main()
{
  bar (0, &x[1]);
  return 0;
}=
