From 4bdd44c4bc5ec2f3655e47cc56a3ade55fed2d26 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Mon, 18 Mar 2013 13:57:33 +0000 Subject: [PATCH] tree-vect-loop-manip.c (vect_create_cond_for_alias_checks): Remove cond_expr_stmt_list argument and do not gimplify the built expression. 2013-03-18 Richard Biener * tree-vect-loop-manip.c (vect_create_cond_for_alias_checks): Remove cond_expr_stmt_list argument and do not gimplify the built expression. (vect_loop_versioning): Adjust. * tree-vect-data-refs.c (vect_create_addr_base_for_vector_ref): Cleanup to use less temporaries. (vect_create_data_ref_ptr): Cleanup.
