re PR rtl-optimization/40761 (IRA memory hog for insanely nested loops)
2012-01-19 Vladimir Makarov <vmakarov@redhat.com> PR rtl-optimization/40761 * ira-int.h (struct ira_loop_tree_node): Add comment for member loop. Add new member loop_num. (IRA_LOOP_NODE_BY_INDEX): Modify the check. (ira_build): Remove the parameter. * ira.c (ira_print_disposition): Use loop_num instead of loop->num. (ira.c): Do not build CFG loops for one region allocation. Remove argument from ira_build call. * ira-build.c (init_loop_tree_node): New function. (create_loop_tree_nodes): Use it. Separate the case when CFG loops are not built. (more_one_region_p): Check current_loops. (finish_loop_tree_nodes): Separate the case when CFG loops are not built. (add_loop_to_tree): Process loop equal to NULL too. (form_loop_tree): Separate the case when CFG loops are not built. Use explicitly number for the root. (rebuild_regno_allocno_maps, create_loop_tree_node_allocnos): Add an assertion. (ira_print_expanded_allocno, loop_compare_func): Use loop_num instead of loop->num. (mark_loops_for_removal): Ditto. Use loop_num instead of loop->num. (mark_all_loops_for_removal): Ditto. (remove_unnecessary_regions): Separate the case when CFG loops are not built. (ira_build): Remove the parameter. Use explicit number of regions when CFG loops are not built. * ira-color.c (print_loop_title): Separate the case for the root node. Use loop_num instead of loop->num. (move_spill_restore): Use loop_num instead of loop->num. * ira-emit.c (setup_entered_from_non_parent_p): Add an assertion. (change_loop): Ditto. (change_loop): Use loop_num instead of loop->num. * ira-lives.c (process_bb_node_lives): Ditto. * ira-costs.c (print_allocno_costs, find_costs_and_classes): Ditto. * ira-conflicts.c (print_allocno_conflicts): Ditto.
