--- Comment #3 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I looked into making loop optimizer to be initialized before all analysis hooks
so inliner can use SCEV.  The issue is that the analysis is organized as a
series of passes over whole program (something I mean to change back, we used
to do it per function that is friendlier to caches). We have no way to
initiazlie SCEV on all functions at once and I do not htink we want to.
We can just do the initialization and rely on fact that another initialization
should not affect code, but it seems hackish.

In any case I think it is something for next stage1, not for GCC 5.

I am assigning myself and setting target milestone.
