tree-vectorizer.h (_loop_vec_info): Add scalar_cost_vec and single_scalar_iteration_cost members.
2015-06-22 Richard Biener <rguenther@suse.de>
* tree-vectorizer.h (_loop_vec_info): Add scalar_cost_vec
and single_scalar_iteration_cost members.
(LOOP_VINFO_SCALAR_ITERATION_COST): New.
(LOOP_VINFO_SINGLE_SCALAR_ITERATION_COST): Likewise.
(vect_get_single_scalar_iteration_cost): Remove.
* tree-vect-data-refs.c (vect_peeling_hash_get_lowest_cost):
Use LOOP_VINFO_SCALAR_ITERATION_COST.
* tree-vect-loop.c (destroy_loop_vec_info): Free
scalar_cost_vec.
(vect_get_single_scalar_iteration_cost): Compute result into
LOOP_VINFO_SINGLE_SCALAR_ITERATION_COST and
LOOP_VINFO_SCALAR_ITERATION_COST. Make static.
(vect_analyze_loop_2): Call vect_get_single_scalar_iteration_cost.
(vect_estimate_min_profitable_iters): Use them.
