* cpphash.h (HASHSTEP): Take character rather than pointer to character. (_cpp_check_directive, _cpp_check_linemarker): Update prototypes. * cpphash.c (cpp_loookup): Update for new HASHSTEP. * cpplex.c (auto_expand_name_space, trigraph_replace, backslash_start, handle_newline, parse_name, INIT_TOKEN_STR, IMMED_TOKEN, PREV_TOKEN_TYPE, PUSH_TOKEN, REVISE_TOKEN, BACKUP_TOKEN, BACKUP_TRIGRAPH, MIGHT_BE_DIRECTIVE, KNOWN_DIRECTIVE): Delete. (handle_newline, check_long_token, skip_escaped_newlines, unterminated): New functions. (ACCEPT_CHAR, SAVE_STATE, RESTORE_STATE): New macros. (parse_identifier): Was parse_name, new implementation. (skip_line_comment, skip_block_comment, skip_whitespace, parse_number, parse_string, trigraph_ok, save_comment, adjust_column, _cpp_get_line): New implementations. (lex_token): New function. Lexes a token at a time, looking forwards. Contains most of the guts of the old lex_line. (lex_line): New implementation, using lex_token to obtain individual tokens. (cpp_scan_buffer): Use the token's line, not the list's line. * cpplib.c (_cpp_check_directive, _cpp_check_linemarker): New implementations. (do_assert): Don't bother setting the answer's list's line. (cpp_push_buffer): Initialise new pfile and read_ahead members of struct cpp_buffer. * cpplib.h (cppchar_t): New typedef. (struct cpp_buffer): read_ahead, pfile and col_adjust are new members. (struct lexer_state): New structure that determines the state and behaviour of the lexer. (IN_DIRECTIVE, KNOWN_DIRECTIVE): New macros. (struct cpp_reader): New member "state". Rename multiline_string_line and multiline_string_column. Delete col_adjust, in_lex_line members. (CPP_BUF_COLUMN): Update. * gcc.dg/cpp/cmdlne-C.c: Remove bogus warning test. From-SVN: r36509
