Rename the struct. * tree-vect-data-refs.c (comp_dr_with_seg_len_pair): Consider steps of data references during sort. (vect_prune_runtime_alias_test_list): Adjust with the change to struct dr_with_seg_len. * tree-vect-loop-manip.c (vect_create_cond_for_alias_checks): Adjust with the change to struct dr_with_seg_len. 2013-11-07 Cong Hou PR tree-optimization/56764 * tree-vect-loop-manip.c (vect_create_cond_for_alias_checks): Combine alias checks if it is possible to amortize the runtime overhead. Return the number of alias checks after merging. * tree-vect-data-refs.c (vect_prune_runtime_alias_test_list): Use the function vect_create_cond_for_alias_checks () to check the number of alias checks.
