Right, but the simplest code is the code that doesn't exist: if the option doesn't exist, there's no need to diagnose anything. The rest of the "C++ ABIs" aren't really their own C++ ABIs, they are just a reflection of the target triple. What is the actual use case? I read the RFC, but ever since I became a manager, my reading comprehension level dropped back to grade school, and I apologize for that. As I understood it, you need a flag that enables all the Itanium ABI extensions (relative vtables, and others) used in Fuchsia, at once. A single relative vtable ABI flag isn't sufficient (would it be?).
