Author: victork Date: Mon Sep 17 09:37:31 2007 New Revision: 128539 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=128539 Log: PR tree-optimization/33319 * tree-vect-analyze.c (vect_same_range_drs): New. (vect_vfa_range_equal): New. (vect_is_duplicate_ddr): Removed. (vect_mark_for_runtime_alias_test): Do not perform marking when optimizing for size or max_param for alias checking is zero. Move the function before vect_analyze_data_ref_dependence. (vect_analyze_data_ref_dependence): Add call to vect_mark_for_runtime_alias_test in two cases when dependence is not clear. (vect_analyze_data_ref_dependences): Do not call to vect_mark_for_runtime_alias_test. (vect_prune_runtime_alias_test_list): New. (vect_analyze_loop): Add call to vect_prune_runtime_alias_test_list. * tree-vect-transform.c (vect_estimate_min_profitable_iters): Update vec_outside_cost. (vect_vfa_segment_size): More compact code, use TYPE_SIZE_UNIT. (vect_create_cond_for_alias_checks): Build the base address of data reference from DR_GROUP_FIRST_DR. (vect_loop_versioning): New. (vect_transform_loop): Add a call to vect_loop_versioning. Remove factored out code.
