--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> --- If someone cares so much about the static branch predictor, they would be a compiler developer. This is the first time I have seen a non-compiler developer care about documenting gcc heuristics. Note there is no one paper. Also if branches are 50/50, the decision can change based on adding another statement and is hard to document otherwise.
