           Summary: overflow builtins are not constexpr
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW

It would be beneficial if overflow builtins [1] could be used in constant
expressions. This would bring Clang in line with GCC 7.x [2].
