diagnostics over to it. There are a few differences between this diagnostic engine and Clang's engine: - Diagnostics are specified by a .def file (Diagnostics.def), rather than via tblgen, which drastically simplifies the build and makes code completion work when you add a new diagnostic. - Calls to the "diagnose()" method are safely typed based on the argument types specified in the .def file, so it's harder to write a diagnostic whose expected arguments (in the string) and whose actual arguments (in the code) don't match. - It uses variadic templates, so it hangs with the cool kids.
