--- Comment #3 from Marc Glisse <glisse at gcc dot gnu.org> ---
I guess it would be possible to have an optional warning, late in the
optimization process, when we see an empty infinite loop:

  <bb 3>:
  goto <bb 3>;

I don't know how many false positives we would get from that, but the
limitation to an empty block might make them rare enough.
