--- Comment #5 from Jan Hubicka <hubicka at ucw dot cz> --- Note that propagation of branch probabilities from callee to caller works only by kind of accident. I originally made branch prediction to be done after early inlining since it makes some patterns branch predictors looks for to appear. with the likely attribute it will only happen with early inlinng and not with late inlining, since there is a chicken-egg problem. To make good inline decisions you already need profile to be computed. So I am not sure we want to convince users these hints are going to be used. Pehraps with allways_inline functions.
