The patch enhances ifcombine pass to recover some non short circuit branches. Basically, it will do the following transformation:Case 1: if (cond1) if (cond2) ==> if (cond1 && cond2)
Hello,it might be more clear if you wrote (cond1 & cond2) so it can't be confused with a short-circuit?
Using branch probabilities to guide the decision would be nice, don't know how hard that would be though.
