/* This structure defines one built-in identifier. A node will be
entered in the hash table under the name NAME, with value VALUE.
There are two tables of these. builtin_array holds all the
"builtin" macros: these are handled by builtin_macro() in
macro.c. Builtin is somewhat of a misnomer -- the property of
interest is that these macros require special code to compute their
expansions. The value is a "builtin_type" enumerator.
operator_array holds the C++ named operators. These are keywords
which act as aliases for punctuators. In C++, they cannot be
altered through #define, and #if recognizes them as operators. In
C, these are not entered into the hash table at all (but see
<iso646.h>). The value is a token-type enumerator. */

Represent column numbers using line-map's source_location. The "next available source_location" is now managed internally by line-maps.c rather than by clients. * line-map.h (struct line_map): New field column_bits. <from_line>: Rename field to start_location. (struct line_maps): New fields highest_location and max_column_hint. (linemap_check_files_exited): New declaration. (linemap_line_start): New declaration. (linemap_add): Remove from_line parameter; use highest_location field. (SOURCE_LINE, LAST_SOURCE_LINE): Modify to use column_bits. (SOURCE_COLUMN, LAST_SOURCE_LINE_LOCATION): New macros. (CURRENT_LINE_MAP): Remove macro. (linemap_position_for_column): New inline function. * line-map.c (linemap_init): Clear new fields. (linemap_check_files_exited): New function, extracted from ... (linemap_free): Use linemap_check_files_exited. (linemap_add): Remove from_line parameter. Various updates. (linemap_line_start): New function. (linemap_lookeup): Update for new field names. * cpphash.h (struct cpp_reader) <map>: Field removed. Because linemap_position_for_column may unpredictably change the current map, it is cleaner and simpler for us to not cache it in cpp_reader. (struct cpp_buffer): New sysp field. Changed warned_cplusplus_comments and from_stage3 to bitfields. * cppinit.c (cpp_read_min_file): pfile->map no longer exists. * cpplib.c (do_line, do_linemarker, _cpp_do_file_change): Get current map using linemap_lookup. (do_linemarker): Also set buffer's sysp field. (destringize_and_run): No longer need to decrement current line. * cppfiles.c (_cpp_stack_file): Set sysp from and in buffer. (search_path_head, open_file_failed): Use buffer's sysp. (cpp_make_system_header): Get current map using linemap_lookup. Also set buffer's sysp flag. * cppmacro.c (_cpp_builtin_macro_text): Likewise use linemap_lookup. * cpphash.h (CPP_INCREMENT_LINE): New macro. (struct cpp_buffer): Moved fields saved_cur, saved_rlimit to ... (struct cpp_reader): ... and adding saved_line_base field. * cpptrad.c (_cpp_overlay_buffer, _cpp_remove_overlay): Update accordingly. Don't adjust line. (_cpp_scan_out_logical_line): Use CPP_INCREMENT_LINE. * cpphash.c (CPP_IN_SYSTEM_HEADER): Replaced macro by ... (cpp_in_system_header): ... new inline function, using buffer's sysp. * cpperror.c (_cpp_begin_message): Update to use cpp_in_system_header. * cpplex.c (_cpp_lex_direct): Likewise. * cppmacro.c (_cpp_builtin_macro_text): Likewise. * cppmacro.c (_cpp_create_definition): Use buffer's sysp field. * cpplib.h (struct cpp_token): Rename line field to src_loc. Remove col field as it is now subsumed by src_loc. * cpperror.c: Update various field, parameter, and macro names. (print_location): If col==0, try SOURCE_COLUMN of line. (cpp_error): Use cur_token's src_loc field, rather than line+col. * cpplib.c (do_diagnostic): Token's src_loc fields replaces line+col. * cpplex.c (_cpp_process_line_notes, _cpp_lex_direct, _cpp_skip_block_comment): Use CPP_INCREMENT_LINE. (_cpp_temp_token): Replace cpp_token's line+col fields by src_loc. (_cpp_get_fresh_line): Don't need to adjust line for missing newline. (_cpp_lex_direct): Use linemap_position_for_column. * c-ppoutput.c (maybe_print_line, print_line): Don't take map parameter. Instead get it from the line_table global. Adjust callers. (print): Remove map field. Replace line field to src_line. (init_pp_output, account_for_newlines, maybe_print_line): Adjust. (cb_line_change): Use SOURCE_COLUMN. Minor optimizations. (pp_file_change): Use MAIN_FILE_P since we cannot checked print.map. Use LAST_SOURCE_LINE_LOCATION to "catch up" after #include. * cpptrad.c (copy_comment): Rename variable. * c-lex.c (map): Remove static variable, for same reason we removed cpp_reader's map field. (cb_line_change, cb_def_pragma, cb_define, cb_undef): Hence we need to call linemap_lookup. (cb_line_change): Token's line field replaced by src_loc. (fe_file_change): Use MAINFILE_P and LAST_SOURCE_LINE macros. Don't save new_map. * cpphash.h, cpperror.c, cpplib.h: Some renames of fileline to source_location. From-SVN: r77663

Partially revert/redo 2003-10-01 change; fix -fworking-directory. * c-ppoutput.c (pp_dir_change): New function. * c-common.h (pp_dir_change): New declaration. * cpplib.h (struct cpp_options): Remove working_directory field. * cppinit.c (cpp_find_main_file, cpp_push_main_file): Merge back to (cpp_read_main_file): as before 10-01. Call _cpp_stack_file. Don't handle -fworking_directory here, but in c_common_post_options. (read_original_directory): Don't back up when done.

(init_c_lex): Don't set dir_change callback here, since we want to set it even if flag_preprocess_only. * c-opts.c (cb_dir_change): Function moved from c-lex.c. (c_common_post_options): Set dir_change callback. Call pp_dir_change if approporiate. (finish_options): Don't call cpp_find_main_file here. Hence remove unneeded parameter and result. Do LC_RENAME for <built-in>. (c_common_post_options): Call cpp_read_main_file here instead. (c_common_init): Update accordingly. (push_command_line_include): Don't cpp_push_main_file.
