Yes, it is, it's missing all of them. Any clang/llvm version 3.5 and above. So it's been broken for a while. We inherit from a clang class that processes preprocessing statements. If we override virtual functions of a certain signature, we can inject our code into the preprocessing process. In this case we're looking for the use of TRICK_ICG. Clang changed the function signature in version 3.5. From 3.5 on our functions were never called, so we never would find TRICK_ICG. I created new signatures for the functions post 3.5 so they will work again.
