--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The big question is how useful is this in real code?
ICC does it, then there must have been a benchmark where this improves but I
don't know which one.

Also it looks like ICC does:
int f(int x)
{
  const p *t = arr[x];
  if (t == square)
    return square(1);
  else
    return add(1);
}
