2007-06-15 Kenneth Zadeck <zadeck@naturalbridge.com> * df.h (DF_FIRST_OPTIONAL_PROBLEM): Removed. (struct df_problem.free_blocks_on_set_blocks): New field. (struct dataflow.optional_p): New field. (df_bb_regno_last_use_find, df_insn_regno_def_p): Removed. (df_live_set_all_dirty): New function. * df-scan.c (df_scan_alloc): Initialize optional_p. (problem_SCAN): Initialize free_blocks_on_set_blocks. * df-core.c (df_set_blocks): Removed use of DF_FIRST_OPTIONAL_PROBLEM. Now uses df_problem.free_blocks_on_set_blocks to determine which blocks are recycled. (df_remove_problem): Removed use of DF_FIRST_OPTIONAL_PROBLEM. (df_finish_pass): Removed use of DF_FIRST_OPTIONAL_PROBLEM. Now uses dataflow.optional_p to determine if problem should be deleted. (rest_of_handle_df_initialize): Only start live problem if -02 or above. (df_bb_regno_last_use_find, df_insn_regno_def_p): Removed. * df-problems.c (df_ru_alloc, df_rd_alloc, df_lr_alloc, df_live_alloc, df_urec_alloc, df_note_alloc): set optional_p. (problem_RU, problem_RD, problem_LR, problem_UREC, problem_CHAIN, problem_NOTE): Initialize free_blocks_on_set_blocks. (df_lr_bb_local_compute): Recompute luids if df_live problem is not active. (df_live_set_all_dirty, df_note_alloc): New function. * regrename.c (merge_overlapping_regs): Change DF_LIVE_* to df_get_live_*. * sched_ebb.c (compute_jump_reg_dependencies): Ditto. * postreload.c (reload_combine): Ditto. * cse.c (cse_extended_basic_block): Ditto. * regmove.c (mark_flags_life_zones): Ditto. * rtlfactoring.c (split_blocks_after_seqs, split_pattern_seq, erase_matching_seqs): Ditto. * bt-load.c (compute_defs_uses_and_gen): Ditto. * integrate (allocate_initial_values): Ditto. * combine.c (reg_dead_at_p): Ditto. * resource.c (mark_target_live_regs): Ditto. * sched-rgn.c (check_live_1, update_live_1): Ditto. * config/sh/sh.c (find_r0_life_regions): Ditto. * global.c (rest_of_handle_global_alloc): Only add back df_live for -O > 1. * local-alloc.c (rest_of_handle_local_alloc): Only remove df_live for -O > 1. * ifcvt.c (dead_or_predicable): Change DF_LIVE_* to df_get_live_*. (if_convert): Make sure df_live is there at -O == 1. (pass_if_after_combine): Cleanup flags. * init-regs.c (initialize_uninitialized_regs): Make sure df_live is there at -O == 1. From-SVN: r125857 |

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.
