--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- If the strlen pass would handle if (__builtin_strlen (a)) return; if we disabled the early folding, then it should be taught to handle whatever it is folded to. Though, I'm not sure it can, there is no code to handle sizes only for certain parts of cfg and others for different ones.
