ktkachov at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ktkachov at gcc dot gnu.org --- Comment #1 from ktkachov at gcc dot gnu.org --- Looks like we want to perform the folds when the exp/log operates on a constant but only when the value being compared to is not constant. If they're both constant the compiler will oscillate between the two at low optimisation levels.
