--- Comment #154 from Teresa Johnson <tejohnson at google dot com> 2012-12-11 19:30:53 UTC --- What was the size of the gcc lto/pgo binary before the change to use the histogram? Was it close to the gcc 4.7 lto/pgo size? In that case that is a very large increase, ~25%. Markus, could you attach to the bug one of the gcda files so that I can see the program summary and figure out how far off the old hot bb threshold is from the new histogram-based one? Also, it would be good to see the -fdump-ipa-inline dumps before and after the regression (if necessary, the before one could be from 4_7).
