1999-03-16 16:06 -0500 Zack Weinberg <zack@rabi.columbia.edu> * cppfiles.c (read_and_prescan): Map backslash-newline to '\r' (which cannot otherwise appear in the processed buffer) and move it out of tokens that it appears in the middle of. Improve performance. (find_position): New function. * cpplib.c: \r (one character) indicates backslash newline, not \\\n (two characters). It cannot appear in the middle of a token. Call CPP_BUMP_LINE (pfile) whenever parsing moves past \n or \r. Increment pfile->lineno whenever a \n is placed into token_buffer. Only one mark can exist at a time, and CPP_BUMP_LINE must not be used while it is active. It is automatically cleared by cpp_pop_buffer and parse_goto_mark. \r is not in is_hor_space or is_space. (NEWLINE_FIX, NEWLINE_FIX1, adjust_position, update_position, count_newlines, parse_move_mark): Removed. (parse_string, copy_comment): New functions. (parse_name): Returns void. (parse_set_mark, parse_clear_mark, parse_goto_mark): Take only one argument, a cpp_reader *. Change for new marking scheme. (skip_comment): Handle CHILL line comments too. Second argument is now first character of comment marker; all callers changed. Issue error for unterminated block comment here. (cpp_skip_hspace): Recognize CHILL comments. (copy_rest_of_line): Likewise. Call skip_comment and parse_string directly, don't go through cpp_get_token. Emit "/**/" for block comments if -traditional (create_definition needs this). (do_define): Don't play with put_out_comments. (cpp_push_buffer): Initialize ->mark to -1. (cpp_buf_line_and_col): Just read out the values in the buffer structure. (output_line_command): Use cpp_buf_line_and_col. Fix formatting. Remove stale code. (cpp_get_token): Break out string parsing code to parse_string. Use skip_comment for CHILL comments too. Use copy_comment for put_out_comments instead of dinking with marks. Remove stale code. Don't call output_line_command unless it's necessary. * cpplib.h (parse_marker): Removed. (struct cpp_buffer): line_base is now a unsigned char *; add `mark' [long], remove `marks' [struct parse_marker *]. (parse_set_mark, parse_clear_mark, parse_goto_mark): Update prototypes. (CPP_BUMP_LINE, CPP_BUMP_BUFFER_LINE): New macros. * cppinit.c (is_hor_space, is_space): '\r' is not considered whitespace. * cppexp.c (cpp_parse_expression): Use cpp_skip_hspace, not SKIP_WHITE_SPACE. * cpphash.c (macarg): Disable line commands while expanding.
