Marc Glisse <glisse at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |diagnostic Severity|major |normal --- 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.
