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. From-SVN: r224723
