--- Comment #7 from Segher Boessenkool <segher at gcc dot gnu.org> --- When maybe_duplicate_computed_goto is asked to duplicate a block with 9189 successors, it damn well should! If that is a bad idea for the case at hand, just do not call maybe_duplicate_computed_goto on such a block! maybe_duplicate_computed_goto should never ever decide to know better than its caller. That way insanity lies.
