--- Comment #6 from Jan Hubicka <hubicka at gcc dot gnu.org> --- This is all bit about luck. We have big_speedup hack that lets us to bypass inline-insns-auto when we know the combination caller+callee improve by given precentage. Because we inline more, caller is now bigger and slower and because we early optimize better callee is faster, so overall speedup is smaller. There are two extra issues with propagating. I will simply fix them and drop the big speedup percentage from 10% to 8%. Honza
