* ipa-pure-const.c (state_from_flags, local_pure_const): Use current_function_name instead of lang_hooks.decl_printable_name. * function.h (fndecl_name): New prototype. * function.c (fndecl_name): New function. * vecir.h (cgraph_node_p): New standard IR VEC type. * trans-mem.c (cgraph_node_p): No need anymore to define it here. * ipa-utils.h (ipa_get_nodes_in_cycle): New prototype. * ipa-utils.c (ipa_get_nodes_in_cycle): New function. * ipa-reference.c: Don't include langhooks.h, and certainly not twice. Fix many formatting issues (long lines, short lines, spacing, etc.). (get_static_name): Use fndecl_name. (dump_static_vars_set_to_file): New function split out from propagate. (union_static_var_sets): New function, union two sets and collapse to all_module_statics as quickly as possible. (intersect_static_var_sets): New function, similar to above. (copy_static_var_set): Renamed from copy_global_bitmap and rewritten to allocate a copy on the same bitmap_obstack as the source set. (propagate_bits): Simplify, and clarify by using union_static_var_sets. (generate_summary): Remove bm_temp. Print UID of promotable globals. (read_write_all_from_decl): Use pass-by-reference, bless C++. (get_read_write_all_from_node): New function, split out from propagate. (propagate): Simplify and clarify with helper functions. Use ipa_get_nodes_in_cycle to walk all nodes in a reduced node. (ipa_reference_read_optimization_summary): Use fndecl_name instead of lang_hooks.decl_printable_name. * rtl.h (print_rtl_single_with_indent): New prototype. * print-rtl.c (print_rtl_single_with_indent): New function. * cfghooks.h (empty_block_p, split_block_before_cond_jump): New hooks. * cfghooks.c (empty_block_p, split_block_before_cond_jump): Implement. * cfgrtl.c (rtl_block_empty_p, rtl_split_block_before_cond_jump): Implement RTL specific hooks. (rtl_cfg_hooks, cfg_layout_rtl_cfg_hooks): Register the new hooks. * tree-cfg.c (gimple_empty_block_p, gimple_split_block_before_cond_jump): Implement GIMPLE specific hooks. (gimple_cfg_hooks): Register the new hooks. * tree-ssa-phiopt.c (empty_block_p): Remove in favor of new hook. From-SVN: r191255
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.
