--- Comment #1 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
There is surprising group of issues with ipa-cp cost model and speculation I
have WIP patches for.
However there is also problem with vectorization of mc_chroma. We vectorized
w/o profile feedback but give up with profile feedback since the expected
number of iterations is lower then the min profitability.
With cascade epilogue it seems that vectorization is a win, so cost model
should consider vectorizatoin with smaller Vf...
