5386 2004-02-11 Per Bothner <per@bothner.com>
5388 Represent column numbers using line-map's source_location.
5389 The "next available source_location" is now managed internally by
5390 line-maps.c rather than by clients.
5391 * line-map.h (struct line_map): New field column_bits.
5392 <from_line>: Rename field to start_location.
5393 (struct line_maps): New fields highest_location and max_column_hint.
5394 (linemap_check_files_exited): New declaration.
5395 (linemap_line_start): New declaration.
5396 (linemap_add): Remove from_line parameter; use highest_location field.
5397 (SOURCE_LINE, LAST_SOURCE_LINE): Modify to use column_bits.
5398 (SOURCE_COLUMN, LAST_SOURCE_LINE_LOCATION): New macros.
5399 (CURRENT_LINE_MAP): Remove macro.

5405 (linemap_line_start): New function.
5406 (linemap_lookeup): Update for new field names.
5407 * cpphash.h (struct cpp_reader) <map>: Field removed. Because
5408 linemap_position_for_column may unpredictably change the current map,
5409 it is cleaner and simpler for us to not cache it in cpp_reader.
5410 (struct cpp_buffer): New sysp field.
5411 Changed warned_cplusplus_comments and from_stage3 to bitfields.
5412 * cppinit.c (cpp_read_min_file): pfile->map no longer exists.
5413 * cpplib.c (do_line, do_linemarker, _cpp_do_file_change): Get
5414 current map using linemap_lookup.
5415 (do_linemarker): Also set buffer's sysp field.
5416 (destringize_and_run): No longer need to decrement current line.
5417 * cppfiles.c (_cpp_stack_file): Set sysp from and in buffer.

5422 * cpphash.h (CPP_INCREMENT_LINE): New macro.
5423 (struct cpp_buffer): Moved fields saved_cur, saved_rlimit to ...
5424 (struct cpp_reader): ... and adding saved_line_base field.

5426 Update accordingly. Don't adjust line.
5427 (_cpp_scan_out_logical_line): Use CPP_INCREMENT_LINE.
5428 * cpphash.c (CPP_IN_SYSTEM_HEADER): Replaced macro by ...
5429 (cpp_in_system_header): ... new inline function, using buffer's sysp.
5430 * cpperror.c (_cpp_begin_message): Update to use cpp_in_system_header.
5431 * cpplex.c (_cpp_lex_direct): Likewise.
5432 * cppmacro.c (_cpp_builtin_macro_text): Likewise.
5433 * cppmacro.c (_cpp_create_definition): Use buffer's sysp field.
5434 * cpplib.h (struct cpp_token): Rename line field to src_loc.
5435 Remove col field as it is now subsumed by src_loc.
5436 * cpperror.c: Update various field, parameter, and macro names.
5437 (print_location): If col==0, try SOURCE_COLUMN of line.
5438 (cpp_error): Use cur_token's src_loc field, rather than line+col.
5439 * cpplib.c (do_diagnostic): Token's src_loc fields replaces line+col.
5440 * cpplex.c (_cpp_process_line_notes, _cpp_lex_direct,
5441 _cpp_skip_block_comment): Use CPP_INCREMENT_LINE.
5442 (_cpp_temp_token): Replace cpp_token's line+col fields by src_loc.
5443 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
5444 (_cpp_lex_direct): Use linemap_position_for_column.
5445 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
5446 parameter. Instead get it from the line_table global. Adjust callers.
5447 (print): Remove map field. Replace line field to src_line.
5448 (init_pp_output, account_for_newlines, maybe_print_line): Adjust.
5449 (cb_line_change): Use SOURCE_COLUMN. Minor optimizations.
5450 (pp_file_change): Use MAIN_FILE_P since we cannot checked print.map.
5451 Use LAST_SOURCE_LINE_LOCATION to "catch up" after #include.
5452 * cpptrad.c (copy_comment): Rename variable.
5453 * c-lex.c (map): Remove static variable, for same reason we removed
5454 cpp_reader's map field.
5455 (cb_line_change, cb_def_pragma, cb_define, cb_undef): Hence we need
5456 to call linemap_lookup.
5457 (cb_line_change): Token's line field replaced by src_loc.
