Arithmetic on such types is a perfectly reasonable notion to have in language-independent code and carry out language-independent optimizations on. There may well be a case for lowering such arithmetic earlier than the present point at which it's lowered (expand), but it isn't obvious that gimplification is the right point for that lowering either. -- Joseph S.
