(dse_step0): Allocate the scratch bitmap on reg_obstack. Initialize the new bitmap obstack and normal obstack. Use XNEWVEC for bb_table. (record_store): Allocate regs_set on reg_obstack. (dse_step1): Allocate regs_live on reg_obstack. (dse_step2_init): Allocate offset_map_n and offset_map_p on the new obstack. (dse_step3_scan): Allocate bitmaps on the new bitmap obstack. (dse_step3): Likewise. (dse_confluence_0): Likewise. (dse_confluence_n): Likewise. (dse_transfer_function): Likewise. (dse_step7): Destroy the new obstacks, and everything allocated on them, in one big sweep. (rest_of_handle_dse): Update. * cfgexpand.c (stack_var_bitmap_obstack): New bitmap obstack. (add_stack_var_conflict): Allocate bitmaps on it. (add_scope_conflicts_1): Likewise. (add_scope_conflicts): Likewise. (update_alias_info_with_stack_vars): Likewise. (init_vars_expansion): Move TREE_USED fiddling expand_used_vars. Initialize the new bitmap obstack. (fini_vars_expansion): Release it. (estimated_stack_frame_size): Use init_vars_expansion to set things up and always clean up at the end. (expand_used_vars): Do the TREE_USED trickery here. Always call fini_vars_expansion. * tree-ssa-live.h (struct tree_live_info_d): Make livein and liveout arrays of bitmap_head to avoid one indirection per bitmap access. (live_on_entry, live_on_exit, live_var_map, live_merge_and_clear, make_live_on_entry): Update. * tree-ssa-live.c (partition_view_bitmap): Don't double-free 'used'. (liveness_bitmap_obstack): New bitmap obstack. (remove_unused_locals): Use it to allocate all bitmaps on. Update for livein/liveout changes in tree-ssa-live.h. (delete_tree_live_info): Release the bitmap obstack. (loe_visit_block, live_worklist, set_var_live_on_entry, calculate_live_on_exit, dump_live_info): Update. (calculate_live_ranges): Initialize the bitmap. * tree-ssa-ter.c (ter_bitmap_obstack): New bitmap obstack. (new_temp_expr_table): Allocate bitmap on it. (make_dependent_on_partition, add_to_partition_kill_list, add_dependence, process_replaceable): Likewise. (find_replaceable_exprs): Initialize and release the new obstack here. * df-problems.c (df_lr_add_problem): Allocate persistent bitmap for out_of_date_transfer_functions on df_bitmap_obstack.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with 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/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
