--- Comment #2 from Jan Hubicka <hubicka at ucw dot cz> --- > I suspect this is most likely the profile updates changes ... Quite possibly. The goal of this excercise is to figure out if there are some bugs in profile estimate or whether passes somehow preffer broken profile or if it is just back luck. Looking at sphinx and fatigue it seems that LRA really may preffer increased profile counts in peeled vectorized loop since it does not understand the fact that putting spill on critical path through the dependnecy graph of the code is not good for out of order execution.
