* sched-rgn.c (haifa_edge, edge_table, NEXT_IN, NEXT_OUT, FROM_BLOCK, TO_BLOCK, nr_edges, in_edges, out_edges, IN_EDGES, OUT_EDGES, build_control_flow, new_edge): Remove. (schedule_insns): Remove edge_table/in_edges/out_edges cleanup. (bitlst, bitlst_table_last, bitlst_table): Remove. (bblst): Store basic_block pointer instead of block index. (bblst_table): Likewise. (edgelst): Store edge pointer instead of edge index. (edgelst_table, edgelst_last): New variables. (extract_bitlst): Rename to ... (extract_edgelst): ... this. Return edge pointers, not indices. (split_edges): Update call. (rgn_edges): Store edge pointers instead of indices. (edge_to_bit): Remove. (EDGE_TO_BIT): Store per-region edge index in edge->aux. (SET_EDGE_TO_BIT): New macro. (is_cfg_nonregular): Check for simple cases of unreachable blocks. (find_rgns): Remove edge_list parameter. Traverse standard CFG data structures instead of haifa_edge et al. Use edge pointers instead of edge indices everywhere. (compute_dom_prob_ps): Use standard CFG data structures. Account for exit edges. (compute_trg_info): Likewise. (propagate_deps): Likewise. (debug_candidate): Account for bblst data structure change. (check_live_1, update_live_1, is_pfree): Likewise. (IS_REACHABLE): Use standard CFG data structures. (init_ready_list): Update bblst_table/edgelst_table allocation. (schedule_region): Update alloc/cleanup code to data structure changes. Use edge->aux to store per-region edge index. (init_regions): No longer call build_control_flow. Do not create edge list any more. From-SVN: r88264
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
