> I could always write a conditional for the hot path up front, but code is for human readers, right? Does C or C++ actually make any promises that it’ll assume the “true” branch of the conditional will be taken? I always assumed that the compiler could make whatever weird decision it wants for that sort of thing. TBH I’d probably just write normal stuff as a function, and then call that function directly in cases where performance is really crucial, if it can be done safely… if such a case exists… |
