Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Note you can only do it if the enum has enumerations from to 0 to power of 2 - 1, if you have say enum E { E0, E1, E2 } and switch (e) { case E0: ... case E1: ... case E2: ... } you can't remove the default case, because calling it with e == 3 is still valid.
