--- Comment #2 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Do we have other PRs reducing to this change?
The patch makes cuntroll to scale down previously incoherent profiles when loop
that does not loop is predicted to loop.
Common source of these loops are vectorized epilogues which I fixed yesterday.
With some luck this may fix fatigue.
