--- Comment #155 from Markus Trippelsdorf <markus at trippelsdorf dot de> 2012-12-11 22:57:14 UTC --- (In reply to comment #154) > 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%. With revision 193914 (before the change) the lto/pgo size is 42115424 bytes. So it looks like Theresa is off the hook. > 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). Will try to post them tomorrow .
