Do I need to produce different branchless assembly? [...] Just a few war stories regarding this from the trenches (= Chrome's JavaScript JIT):

The conclusion I draw from your mail, at last for our case, is: Don’t bother (and keep the compiler code simple). Is that a correct reading?

Greetings, Joachim
