--- Comment #3 from Segher Boessenkool <segher at gcc dot gnu.org> --- The first testcase has (at expand time) if (_13 unord _14) which doesn't mean anything with -ffast-math (-Ofast): unordered does not *exist*. The second testcase is similar, but we generate that unordered from the builtin. Should we allow that builtin with -ffast-math at all? It makes no real sense.
