More like history, where the call comes from.
Oddly enough the price of branch misdirection has become lower as not the entire pipeline needs to be thrown away but also due to hyper threading taking the slack.
Flip note: with 'recent' developments of Spectre, one'd think branch prediction got into the lime light. Truth be told, though, not many would be able to write constant time 'fizz buzz' (can try it on your own, bonus points to having constant time int->string conversion)
