From 4aab792de6d092becf03e1d23f74a1ec2047fc27 Mon Sep 17 00:00:00 2001 From: Kazu Hirata Date: Fri, 27 May 2005 22:06:46 +0000 Subject: basic-block.h (basic_block_def): Add phi_nodes and predictions. * basic-block.h (basic_block_def): Add phi_nodes and predictions. Remove tree_annotations. * predict.c (tree_predicted_by_p, tree_predict_edge, combine_predictions_for_bb): Adjust references to predictions. * tree-cfg.c (init_empty_tree_cfg, create_bb): Don't call create_block_annotation. (create_block_annotation, free_blocks_annotatios, clear_blocks_annotations): Remove. (dump_cfg_stats): Don't print out the memory spent on bb_ann_d. (delete_tree_cfg_annotations): Don't call free_blocks_annotations. * tree-flow-inline.h (bb_ann): Remove. (phi_nodes, set_phi_nodes): Update references to phi_nodes. * tree-flow.h (bb_ann_d): Remove. * tree-if-conv.c (process_phi_nodes): Update a reference to phi_nodes. * tree-phinodes.c (reserve_phi_args_for_new_edge, create_phi_node, remove_phi_node): Likewise. * tree-pretty-print.c (dump_generic_bb_buff): Don't call bb_ann. * tree-ssa-dom.c (threaded_blocks): New. (tree_ssa_dominator_optimize): Initialize, clear, and free threaded_blocks. Update a call to thread_through_all_blocks. (thread_across_edge): Use threaded_blocks instead of setting incoming_edge_threaded. * tree-ssa-threadupdate.c (threaded_through_all_blocks): Take a bitmap of blocks that are threaded through. * tree.h: Move the prototype of threaded_through_blocks to tree-flow.h.
