phase opt and generate just combine all the optimization times together, so it is same 7 seconds as in the ICF pass :) 1GB of function bodies just to elimnate 2-3% of code seems quite alot. Do you have any idea how many of those turns out to be different? It would be nice to be able to release the duplicate bodies from memory after the equivalency was stablished.... Honza > > Martin
