No explanation whatsoever. Why the branch predictor is not "invoked" in the first version of the function?

Because it's most likely using a conditional move.

But I don't see the post going into investigating this at all. Yes, most likely that is what is going on but I don't understand the point of the OP post is if the real reason of the difference in the branch predictor behavior is not explained.
