--- Comment #5 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Nick Desaulniers from comment #4) > Thanks for the feedback, in https://reviews.llvm.org/rL369791, Nathan made > [unsigned] char -> [unsigned]short warn only for -Wformat-pedantic, not > -Wformat. there's a request for GCC to support -Wformat-pedantic, too, in bug 67479, so IMO this bug should stay open as a reminder to make GCC's -Wformat-pedantic warn on this, too, once the flag is added.
