Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think it returns false if it is has a type which isn't representable with the particular range. Which isn't the case here. The type is representable, just the range is undefined_p ().
