Support non-masked epilogue vectoriziation
gcc/
2016-11-16 Yuri Rumyantsev <ysrumyan@gmail.com>
* params.def (PARAM_VECT_EPILOGUES_NOMASK): New.
* tree-if-conv.c (tree_if_conversion): Make public.
* * tree-if-conv.h: New file.
* tree-vect-data-refs.c (vect_analyze_data_ref_dependences) Avoid
dynamic alias checks for epilogues.
* tree-vect-loop-manip.c (vect_do_peeling): Return created epilog.
* tree-vect-loop.c: include tree-if-conv.h.
(new_loop_vec_info): Add zeroing orig_loop_info field.
(vect_analyze_loop_2): Don't try to enhance alignment for epilogues.
(vect_analyze_loop): Add argument ORIG_LOOP_INFO which is not NULL
if epilogue is vectorized, set up orig_loop_info field of loop_vinfo
using passed argument.
(vect_transform_loop): Check if created epilogue should be returned
for further vectorization with less vf. If-convert epilogue if
required. Print vectorization success for epilogue.
* tree-vectorizer.c (vectorize_loops): Add epilogue vectorization
if it is required, pass loop_vinfo produced during vectorization of
loop body to vect_analyze_loop.
* tree-vectorizer.h (struct _loop_vec_info): Add new field
orig_loop_info.
(LOOP_VINFO_ORIG_LOOP_INFO): New.
(LOOP_VINFO_EPILOGUE_P): New.
(LOOP_VINFO_ORIG_VECT_FACTOR): New.
(vect_do_peeling): Change prototype to return epilogue.
(vect_analyze_loop): Add argument of loop_vec_info type.
(vect_transform_loop): Return created loop.
