1999-04-26 19:16 -0400 Zack Weinberg <zack@rabi.columbia.edu>
* cpphash.c (dump_definition): New function.
* cpphash.h: Prototype it.
* cpplib.c (handle_directive): Don't output anything here.
Streamline.
(pass_thru_directive): Take a length, not a pointer to the
end. All callers changed.
(do_define): Handle -dD, -dN, -g3 entirely here. Streamline.
(do_include): Handle -dI here.
(do_ident): Correct to match cccp.
(do_pragma): Copy the pragma through here.
(do_assert, do_unassert): Tidy.
* cppinit.c (cpp_finish): If -dM was specified, walk the macro
hash table and call dump_definition on all the entries.
* cppmain.c: cpp_finish may produce output.
From-SVN: r26659
1999-04-14 12:37 -0400 Zack Weinberg <zack@rabi.columbia.edu>
* cpperror.c, cppexp.c, cpplib.c: Never call abort.
* cpphash.c: Only call abort when we detect corruption of the
malloc arena.
* cppmain.c: Don't define fatal or fancy_abort.
From-SVN: r26442
1999-04-12 14:55 -0400 Zack Weinberg <zack@rabi.columbia.edu>
* cpphash.c (collect_expansion, macroexpand,
push_macro_expansion): Make the escape character in macro
buffers '\r', not '@'. Remove code to protect literal
occurences of the escape character; '\r' cannot appear
in a macro buffer unless we put it there.
* cpplib.c (skip_comment, copy_comment, cpp_skip_hspace,
copy_rest_of_line, cpp_get_token, parse_string,
parse_assertion): '\r' might be a backslash-newline marker, or
it might be a macro escape marker, depending on
CPP_BUFFER (pfile)->has_escapes. '@' is not a special
character.
* cpplib.h: Update commentary.
From-SVN: r26371
1999-04-09 22:58 -0400 Zack Weinberg <zack@rabi.columbia.edu>
* cpphash.c (special_symbol): When expanding __LINE__, use the
top file buffer, not the top buffer.
From-SVN: r26319
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.
From-SVN: r25802
1999-02-25 17:14 -0500 Zack Weinberg <zack@rabi.columbia.edu>
* cpphash.c (install): Rename to cpp_install, add cpp_reader*
first argument. All callers changed.
(hashtab): Removed.
(cpp_lookup, cpp_install): Change all refs to hashtab to
pfile->hashtab.
(cpp_hash_cleanup): Removed.
* cpphash.h: Adjust prototypes.
* cpplib.h (struct cpp_reader): Add hashtab pointer.
* cppinit.c (cpp_reader_init): Also allocate space for the
hashtab.
(cpp_cleanup): Delete all macros and free the hashtab.
From-SVN: r25441
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.
(eval_if_expression): Drop code to insert and remove the
"defined" special symbol.
* cpplib.h: Remove SELF_DIR_DUMMY (no longer used). Remove
T_*_TYPE and T_SPEC_DEFINED from enum node_type; add T_STDC.
* cpphash.c (install): Drop the `ivalue' parameter. Constify
the `value' parameter. All callers changed.
* cpphash.h (install): Change prototype to match.
(union hashval): Remove `ival' member.
* cppexp.c (cpp_lex): Handle `defined' here.
From-SVN: r25097
1998-12-15 Zack Weinberg <zack@rabi.phys.columbia.edu>
* cpphash.h (union hash_value): Remove `keydef' member, add a
`struct hashnode *aschain' member for #assert.
* cpplib.c (struct tokenlist_list, struct
assertion_hashnode): Delete structure definitions.
(assertion_install, assertion_lookup, delete_assertion,
check_assertion, compare_token_lists, reverse_token_list,
read_token_list, free_token_list): Delete functions.
(parse_assertion): New function.
(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.
From-SVN: r24325
* cppexp.c: When forcing unsigned comparisons, cast both sides
of the operation.
* cpphash.h: Move static declaration of hashtab[]...
* cpphash.c: ...here.
* cpplib.c: Cast difference of two pointers to size_t before
comparing it to size_t. Cast signed to unsigned
before comparing to size_t. (FIXME: struct argdata should use
unsigned buffer sizes.)
* cpplib.h (struct cpp_reader): Declare token_buffer_size as
unsigned int. (CPP_WRITTEN): Cast return value to size_t.
(CPP_RESERVE): Parenthesize N for evaluation order, cast to
size_t before comparison.
