From 473a4325cc7635bc68482cb0236557d00a647be3 Mon Sep 17 00:00:00 2001 From: Diego Novillo Date: Fri, 9 Jul 2004 11:16:11 -0400 Subject: [PATCH] re PR tree-optimization/15555 (compute_may_alias failes when scheduled again) Fix PR tree-optimization/15555 * tree-dfa.c (dump_variable): If the variable is a pointer SSA_NAME, also dump its points-to information. * tree-flow.h (struct ptr_info_def): Add field is_dereferenced. (dump_points_to_info_for): Declare. (debug_points_to_info_for): Declare. * tree-optimize.c (init_tree_optimization_passes): Add a second alias analysis pass after DOM2. Move pass_del_pta to a later spot. * tree-ssa-alias.c (compute_points_to_and_addr_escape): Do not create a name tags when we find a dereferenced pointer. Just mark the pointer dereferenced. (collect_points_to_info_for): Move code to clear points-to information to create_name_tags. (create_name_tags): New function. (compute_flow_sensitive_aliasing): Call it. (setup_pointers_and_addressables): Mark type tags for renaming here instead of ... (create_memory_tag): ... here. (merge_pointed_to_info): Do not merge PT_MALLOC attributes. (dump_points_to_info_for): Declare extern. (debug_points_to_info_for): New function.
