--- Comment #8 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I see. compute_uninlined_call_time uses counts when they are available and
frequencies when they are not. It makes sense that dropping count to 0 will
lead to change of compute_uninlined_call_time. I am bit surprised it is that
large (it would be nice to know why).
Otherwise I have WIP path that gets rid of frequencies completely, so it will
fix this problem. I will try to finish it soon.
Thanks a lot for looking into this!
