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.

(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.

Don't adjust line. (_cpp_scan_out_logical_line): Use CPP_INCREMENT_LINE. * cpphash.c (CPP_IN_SYSTEM_HEADER): Replaced macro by ...

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
