The part I saw that looked interesting to me was: https://github.com/llvm-mirror/clang/blob/master/utils/TableGen/ClangDiagnosticsEmitter.cpp#L1786 but I see now that's only for diagnostic groups. You may need to extend this functionality to get the behavior we want, but that can always be done in a follow-up patch which also adds the documentation to the diagnostic flag.
