--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Started with r10-3106-g46dfa8ad6c18feb45d35734eae38798edb7c38cd Anyway, I wonder if this isn't similar to the cases where the inliner optimistically assumed that __builtin_constant_p will fold to true but didn't actually fold it that way, and then later on that didn't happen?
