dschuff added a comment. Yeah. Or not; I think you can still use `__float128` types in clang, so if you did that then it would use these methods too. And as long as `long double` is f64 then none of these functions would get pulled into every program that uses printf (which is the case now), so it wouldn't impose any cost on anyone that doesn't actually use f128. So in that case there's not really a reason not to have it.
