Ok.

Hi All,
Here is updated patch containing missed change in
slpeel_tree_peel_loop_to_edge which prevents renaming of exit PHI uses
in inner loop.
ChangeLog:
2015-06-29 Yuri Rumyantsev
* tree-vect-loop-manip.c (rename_variables_in_bb): Add argument
to allow renaming of PHI arguments on edges inc
Richard,
I attached updated patch.
You asked me to explain why I did changes for renaming.
If we do not change PHI arguments for inner loop header we can get the
following IR:
source outer loop:
: outer-loop header
# i_45 = PHI <0(4), i_18(9)>
# .MEM_17 = PHI <.MEM_4(D)(4), .MEM_44(9)>

Thanks a lot Richard for your review.
I presented updated patch which is not gated by force_vectorize.
I added test on outer-loop in vect_enhance_data_refs_alignment
and it returns false for it because we can not improve dr alighment
through outer-loop peeling in general. So I assume that only
