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.

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.

1999-03-15 21:39 -0500 Zack Weinberg <zack@rabi.columbia.edu> * cppinit.c: Instead of one pending list, keep separate lists for each category of pending option: -D/-U, -A, -include, -imacros. Move the four partial include-path lists into the pending block. Use head and tail pointers so we don't ever have to reverse the lists. (cpp_start_read): Break out blocks of code to their own functions: install_predefs and initialize_dependency_output. Use path_include for C_INCLUDE_PATH and friends as well as CPATH. Remove include_defaults gunk. Warn about the combination of -lang-chill and -trigraphs. Optimize string bashing. Walk each pending list once, deallocating as we go. (append_include_chain): Brought over from cppfiles.c. Mark dirs as system include dirs if and only if appending to system include path. If opts->verbose, print a notice when a dir is dropped from the include path because it doesn't exist. Fix memory leak: this function is not supposed to copy its DIR argument. (nreverse_pending, push_pending): Removed. (APPEND): New macro for adding to pending lists. (path_include): Can now add to any partial include path. (base_name): Bring over from cccp.c. (cpp_options_init): Allocate the pending block. (cpp_handle_option): Add --version. Exit after --help. Fix formatting. Order -ifoo options by frequency of usage.

(finclude): Fix excessive cleverness in setting fp->system_header_p. (actual_directory): Set x->sysp from CPP_BUFFER (pfile)->system_header_p so that one system header may include another with "". (deps_output): Fix double adjustment of deps_size which would cause all dependencies after the first two lines to be lost. * cpplib.c (cpp_unassert): New function. * cpplib.h: Lay out struct cpp_pending here.

1999-02-08 23:25 -0500 Zack Weinberg <zack@midnite.ec.rhno.columbia.edu> * cpplib.c (special_symbol): Rewrite. Don't copy things multiple times. Handle __STDC__ specially. T_CONST indicates a constant /string/. Don't handle T_*_TYPE and T_SPEC_DEFINED. Use cpp_buf_line_and_col instead of adjust_position. Determine the file buffer only if needed. (initialize_builtins): Handle __SIZE_TYPE__, __PTRDIFF_TYPE__, __WCHAR_TYPE__, __USER_LABEL_PREFIX__, and __REGISTER_PREFIX__ with T_CONST special hashtab entries. Don't provide __OBJC__; the driver does that. Provide __STDC_VERSION__, using T_CONST. Use T_STDC for __STDC__. Give install the length of all symbols defined.

(make_assertion): Rename cpp_assert, remove redundant syntax checks, export. (cpp_options_init): Don't init things to zero twice. (cpp_expand_to_buffer): Use memcpy, not a char-by-char loop.

(read_and_prescan): New function, replaces safe_read, converts and/or warns about trigraphs, silently converts odd line terminators (\r, \n\r, \r\n). Warns about no newline at EOF. (finclude): Use read_and_prescan; turn off nonblocking mode on the input descriptor; remove file-size-examination and no-newline-at-EOF gunk which is longer necessary; be more careful about checking that we've been handed a legitimate file to read (only real files, pipes, and ttys are acceptable). * cpplib.h (cpp_options): Rename no_trigraphs flag to `trigraphs' and invert its sense. (trigraph_table): Declare. (cpp_warning_with_line): Prototype. * cpplib.c: Remove all references to trigraph_pcp. Define trigraph_table; initialize it in initialize_char_syntax.

(new_include_prefix): Constify char* parameters. * cppfiles.c (read_name_map): Likewise. (append_include_chain): Likewise.

Don't use parse markers; use a bare pointer into the buffer. Use copy/skip_rest_of_line instead of doing it by hand. Remove `return on any directive' mode which was never used, and take only one argument. (consider_directive_while_skipping): New function, subroutine of skip_if_group. Logic streamlined a bit.

Pretty-print. (eval_if_expression, do_define, do_line, do_include, do_undef, do_error, do_pragma, do_ident, do_if, do_xifdef, do_else, do_elif, do_sccs, do_assert, do_unassert, do_warning): Take only two args.

(cpp_cleanup): Don't destroy the assertion_hashtable. (do_assert): Gut and rewrite. #assert foo (bar) places entries for `#foo' and `#foo(bar)' in the macro hash table, type T_ASSERT. The value union's `aschain' member is used to chain all answers for a given predicate together. (do_unassert): Also rewritten. Take an un-asserted answer off the chain from its predicate and call delete_macro on the hashnode, or walk a predicate chain calling delete_macro on all the entries. (cpp_read_check_assertion): Simply call parse_assertion to get the canonical assertion name, and look that up in the hash table. * cpplib.h (ASSERTION_HASHNODE,ASSERTION_HASHSIZE,assertion_hashtab): Removed. * cpphash.c (install): Use bcopy instead of an explicit loop to copy the macro name. * cppexp.c (cpp_lex): Convert the result of cpp_read_check_assertion to a `struct operation' directly; don't go through parse_number.

(struct cpp_reader): Add pointer to chain of `actual directory' include searchpath entries. (struct file_name_list): Add *alloc pointer for the sake of the actual-directory chain. Move definition of HOST_WIDE_INT here. (cpp_parse_escape): Change prototype to match changes in cppexp.c. * cppfiles.c (actual_directory): New function. (finclude): Use it to initialize the buffer's actual_dir entry. (find_include_file): We don't need to fix up max_include_len here. * cpplib.c (do_include): Don't allocate a file_name_list on the fly for current directory "" includes, use the one that's been preallocated in pfile->buffer->actual_dir. Hoist out duplicate code from the search_start selection logic. (cpp_reader_init): Initialize pfile->actual_dirs. Remove definition of HOST_WIDE_INT. Change calls to cpp_parse_escape to match changes in cppexp.c (note hardcoded MASK, which is safe since this is the source character set). * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c to handle wide character constants in #if directives. The function now returns a HOST_WIDE_INT, and takes a third argument which is a binary mask for all legal values (0x00ff for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK.
