--- Comment #28 from Jan Hubicka <hubicka at ucw dot cz> --- > On SPEC2000 the latest changes look good, compared to the old predictor gap > improved by 10% and INT/FP by 0.8%/0.6%. I'll run SPEC2006 tonight. It is rather surprising you are seeing such large changes for one branch predictor change. Is most of it really comming just from the bb-reorder changes? On x86 the effect is mostly within noise and on Itanium Gap improve by 2-3%. It may be interesting to experiment with reorderin and prediction more on this target. Honza
