Clang (and GCC) compilation errors can come with suggestions on how to fix them: "Fix-it Hints". Does Clang (or maybe another LLVM tool) have an option which would apply these hints? I don't see one in https://clang.llvm.org/docs/UsersManual.html. Obviously such a program could be written using -fdiagnostics-parseable-fixits; that's not what I am asking about.
Yes.
