The latter. Personally I’m dubious on the entire idea of pp_hot. I don’t know if it *ever* made any sense (has anyone ever run any measurements on that?), but among other factors, compilers today have gotten a whole lot smarter in some ways, and just letting the compiler see everything at once and make its own calls is usually the best way to optimise (which is as it should be, thankfully).
