--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
As a consequence of the
andl    $1, %eax
we produce 1 for odd numbers only:

enum E : bool { One, Two };

int
f1 (int x)
{
  return (E) x;
}

int
main ()
{
  if (f1 (6) != 1)
    __builtin_abort ();
  if (f1 (7) != 1)
    __builtin_abort ();
}
