I will take a look. Also could you please make a patch to make maybe_hot_count_p to use hitogram driven cutoff? Otherwise the histograms would be completely unused for 4.8 and it would be stupid to carry all the extra data for no use. I would like this to be done soon, since I plan to base some of inliner re-tunning to be based on this. The mismatch is independent problem, yes. Honza
