Cleanups to do:-
|
|
|
|
|
|
|
|
o -dM and with _cpp_dump_list: too many \n output.
|
|
|
|
o Put a printer object in cpp_reader?
|
|
|
|
o Check line numbers assigned to all errors.
|
|
|
|
o Replace strncmp with memcmp almost everywhere.
|
|
|
|
o lex_line's use of cur_token, flags and list->token_used is a bit opaque.
|
|
|
|
o Convert do_ functions to return void. Kaveh thinks its OK; and said he'll
|
|
|
|
give it a run when we've got some code.
|
|
|
|
o Distinguish integers, floats, and 'other' pp-numbers.
|
|
|
|
o Store ints and char constants as binary values.
|
|
|
|
o New command-line assertion syntax.
|
|
|
|
o Work towards functions in cpperror.c taking a message level parameter.
|
|
|
|
If we do this, merge the common code of do_warning and do_error.
|
|
|
|
o Comment all functions, and describe macro expansion algorithm.
|
|
|
|
o Move as much out of header files as possible.
|
|
|
|
o Remove single quote pairs `', and some '', from diagnostics.
|
|
|
|
o Correct pastability test for CPP_NAME and CPP_NUMBER.

cpplib.h (struct cpp_name): Now struct cpp_string.
* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

cpplib.h (struct cpp_name): Now struct cpp_string.
* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

cpplib.h (struct cpp_name): Now struct cpp_string.
* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,

cpplib.h (struct cpp_name): Now struct cpp_string.
* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

The original lexer in cpplib was made up of two passes: a first pass
|
|
|
|
that replaced trigraphs and deleted esacped newlines, and a second
|
|
|
|
pass that tokenized the result of the first pass. Tokenisation was
|
|
|
|
performed by peeking at the next character in the input stream. For
|
|
|
|
example, if the input stream contained "!=", the handler for the !
|
|
|
|
character would peek at the next character, and if it were a '='
|
|
|
|
would skip over it, and return a "!=" token, otherwise it would
|
|
|
|
return just the "!" token.

To implement a single-pass lexer, this peeking ahead is unworkable.
|
|
|
|
An arbitrary number of escaped newlines, and trigraphs (in particular
|
|
|
|
??/ which translates to the escape \), could separate the '!' and '='
|
|
|
|
in the input stream, yet the next token is still a "!=".

Suppose instead that we lex by one logical line at a time, producing
|
|
|
|
a token list or stack for each logical line, and when seeing the '!'
|
|
|
|
push a CPP_NOT token on the list. Then if the '!' is part of a
|
|
|
|
longer token ("!=") we know we must see the remainder of the token by
|
|
|
|
the time we reach the end of the logical line. Thus we can have the
|
|
|
|
'=' handler look at the previous token (at the end of the list / top
|
|
|
|
of the stack) and see if it is a "!" token, and if so, instead of
|
|
|
|
pushing a "=" token revise the existing token to be a "!=" token.

This works in the presence of escaped newlines, because the '\' would
|
|
|
|
have been pushed on the top of the stack as a CPP_BACKSLASH. The
|
|
|
|
newline ('\n' or '\r') handler looks at the token at the top of the
|
|
|
|
stack to see if it is a CPP_BACKSLASH, and if so discards both.
|
|
|
|
Otherwise it pushes the newline (CPP_VSPACE) token as normal. Hence
|
|
|
|
the '=' handler would never see any intervening escaped newlines.

To make trigraphs work in this context, as in precedence trigraphs
|
|
|
|
are highest and converted before anything else, the '?' handler does
|
|
|
|
lookahead to see if it is a trigraph, and if so skips the trigraph
|
|
|
|
and pushes the token it represents onto the top of the stack. This
|
|
|
|
also works in the particular case of a CPP_BACKSLASH trigraph.

To the preprocessor, whitespace is only significant to the point of
|
|
|
|
knowing whether whitespace precedes a particular token. For example,
|
|
|
|
the '=' handler needs to know whether there was whitespace between it
|
|
|
|
and a "!" token on the top of the stack, to make the token conversion
|
|
|
|
decision correctly. So each token has a PREV_WHITE flag to
|
|
|
|
indicate this - the standard permits consecutive whitespace to be
|
|
|
|
regarded as a single space. The compiler front ends are not
|
|
|
|
interested in whitespace at all; they just require a token stream.
|
|
|
|
Another place where whitespace is significant to the preprocessor is
|
|
|
|
a #define statment - if there is whitespace between the macro name
|
|
|
|
and an initial "(" token the macro is "object-like", otherwise it is
|
|
|
|
a function-like macro that takes arguments.
|
|
|
|
|
|
|
|
However, all is not rosy. Parsing of identifiers, numbers, comments
|
|
|
|
and strings becomes trickier because of the possibility of raw
|
|
|
|
trigraphs and escaped newlines in the input stream.
|
|
|
|
|
|
|
|
The trigraphs are three consecutive characters beginning with two
|
|
|
|
question marks. A question mark is not valid as part of a number or
|
|
|
|
identifier, so parsing of a number or identifier terminates normally
|
|
|
|
upon reaching it, returning to the mainloop which handles the
|
|
|
|
trigraph just like it would in any other position. Similarly for the
|
|
|
|
backslash of a backslash-newline combination. So we just need the
|
|
|
|
escaped-newline dropper in the mainloop to check if the token on the
|
|
|
|
top of the stack after dropping the escaped newline is a number or
|
|
|
|
identifier, and if so to continue the processing it as if nothing had
|
|
|
|
happened.
|
|
|
|
|
|
|
|
For strings, we replace trigraphs whenever we reach a quote or
|
|
|
|
newline, because there might be a backslash trigraph escaping them.
|
|
|
|
We need to be careful that we start trigraph replacing from where we
|
|
|
|
left off previously, because it is possible for a first scan to leave
|
|
|
|
"fake" trigraphs that a second scan would pick up as real (e.g. the
|
|
|
|
sequence "????/\n=" would find a fake ??= trigraph after removing the
|
|
|
|
escaped newline.)
|
|
|
|
|
|
|
|
For line comments, on reaching a newline we scan the previous
|
|
|
|
character(s) to see if it escaped, and continue if it is. Block
|
|
|
|
comments ignore everything and just focus on finding the comment
|
|
|
|
termination mark. The only difficult thing, and it is surprisingly
|
|
|
|
tricky, is checking if an asterisk precedes the final slash since
|
|
|
|
they could be separated by escaped newlines. If the preprocessor is
|
|
|
|
invoked with the output comments option, we don't bother removing
|
|
|
|
escaped newlines and replacing trigraphs for output.
|
|
|
|
|
|
|
|
Finally, numbers can begin with a period, which is pushed initially
|
|
|
|
as a CPP_DOT token in its own right. The digit handler checks if the
|
|
|
|
previous token was a CPP_DOT not separated by whitespace, and if so
|
|
|
|
pops it off the stack and pushes a period into the number's buffer
|
|
|
|
before calling the number parser.

cpplib.h (struct cpp_name): Now struct cpp_string.
* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

cpplib.h (struct cpp_name): Now struct cpp_string.
* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.

* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.

return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.

it returns VSPACE. Remove check for trailing space after
CPP_COMMENT.

checks. Don't push the buffer till after we're done with
them.

(cpp_push_buffer): Don't set new->alimit. Set new->mark
appropriately.

hspace before calling _cpp_parse_assertion. Remove all sets
of only_seen_white. Treat '\f' as hspace. Don't do anything
special with '\n' here.
(maybe_macroexpand): Handle T_EMPTY hash entries without
pushing a buffer at all.

incrementing the line number here. Clear
potential_control_macro as well as only_seen_white, if
appropriate.

(_cpp_get_define_token): New function, basically like
_cpp_get_directive_token was but doesn't eat horizontal space.
Don't do anything with only_seen_white here.

an error for a bogus directive, unless -lang-asm. Use
TRAD_DIRECT_P. Loop calling handler functions till one returns
zero.

Don't call _cpp_output_line_command.
(consider_directive_while_skipping): Use _cpp_get_directive_token.
Issue -Wtraditional warnings as appropriate. Don't complain
about unrecognized directives. If we are to stop skipping,
return the number of the directive that ended the skip.
(skip_if_group): Use _cpp_get_directive_token. Turn off macro
expansion and line commands while skipping. Return the result
of consider_directive_while_skipping, if nonzero.
(do_endif): Just set potential_control_macro here.
(validate_else): Use _cpp_get_directive_token.
(do_assert, do_unassert): Don't save pointers into the
token_buffer across calls to the lexer. Use
_cpp_get_directive_token.
* cpplib.h (cpp_buffer): Remove alimit and colno. Make mark a
pointer, not an offset. Replace 'data', which was a generic
pointer, with 'macro', which points to a struct hashnode.
(cpp_reader): Add 'potential_control_macro' pointer.
* cpphash.h (T_UNUSED): Replace with T_EMPTY.
(CPP_BUF_GET, CPP_FORWARD): Delete.

(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.

return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

cpphash.c (CPP_IS_MACRO_BUFFER, [...]): Delete.
* cpphash.c (CPP_IS_MACRO_BUFFER, FORWARD, PEEKC): Delete.
(macro_cleanup): No need to cast pbuf->macro.
(collect_expansion): Use _cpp_get_define_token. Goto done if
it returns VSPACE. Remove check for trailing space after
CPP_COMMENT.
(_cpp_create_definition): Don't diddle flags here. Return
directly on error.
(unsafe_chars): Handle c1 being EOF.
(push_macro_expansion): Use unsafe_chars for both accidental-paste
checks. Don't push the buffer till after we're done with
them.
* cpplex.c (PEEKBUF, GETBUF, FORWARDBUF): New.
(PEEKN, FORWARD, GETC, PEEKC): Use them.
(cpp_push_buffer): Don't set new->alimit. Set new->mark
appropriately.
(_cpp_parse_assertion): Don't NUL terminate.
(_cpp_lex_token): Fix -traditional macro handling. Don't skip
hspace before calling _cpp_parse_assertion. Remove all sets
of only_seen_white. Treat '\f' as hspace. Don't do anything
special with '\n' here.
(maybe_macroexpand): Handle T_EMPTY hash entries without
pushing a buffer at all.
(cpp_get_token): Handle clearing only_seen_white here. Handle
incrementing the line number here. Clear
potential_control_macro as well as only_seen_white, if
appropriate.
(cpp_get_non_space_token): Don't eat CPP_POP tokens.
(_cpp_get_define_token): New function, basically like
_cpp_get_directive_token was but doesn't eat horizontal space.
Don't do anything with only_seen_white here.
(_cpp_get_directive_token): Just call _cpp_get_define_token
repeatedly till it returns non-hspace.
* cpplib.c (PEEKN, FORWARD, GETC, PEEKC): Delete.
(conditional_skip, skip_if_group): Return int.
(DIRECTIVE_TABLE): Change origin of all conditional directives
to "COND".
(TRAD_DIRECT_P): New macro.
(_cpp_handle_directive): Use _cpp_get_directive_token. Issue
an error for a bogus directive, unless -lang-asm. Use
TRAD_DIRECT_P. Loop calling handler functions till one returns
zero.
(get_macro_name): Don't diddle flags here.
(do_define): Diddle flags here. Use _cpp_get_directive_token.
Create T_EMPTY nodes for #define macro /* nothing */.
(do_undef): Don't copy the name. Use _cpp_get_directive_token.
Use hp->name when calling pass_thru_directive.
(do_if, do_else, do_elif, do_ifdef, do_ifndef, conditional_skip):
Return the result of conditional_skip and/or skip_if_group.
Don't call _cpp_output_line_command.
(consider_directive_while_skipping): Use _cpp_get_directive_token.
Issue -Wtraditional warnings as appropriate. Don't complain
about unrecognized directives. If we are to stop skipping,
return the number of the directive that ended the skip.
(skip_if_group): Use _cpp_get_directive_token. Turn off macro
expansion and line commands while skipping. Return the result
of consider_directive_while_skipping, if nonzero.
(do_endif): Just set potential_control_macro here.
(validate_else): Use _cpp_get_directive_token.
(do_assert, do_unassert): Don't save pointers into the
token_buffer across calls to the lexer. Use
_cpp_get_directive_token.
* cpplib.h (cpp_buffer): Remove alimit and colno. Make mark a
pointer, not an offset. Replace 'data', which was a generic
pointer, with 'macro', which points to a struct hashnode.
(cpp_reader): Add 'potential_control_macro' pointer.
* cpphash.h (T_UNUSED): Replace with T_EMPTY.
(CPP_BUF_GET, CPP_FORWARD): Delete.
(CPP_IN_COLUMN_1, ADJACENT_TO_MARK): New macros.
(CPP_IS_MACRO_BUFFER, CPP_SET_BUF_MARK, CPP_GOTO_BUF_MARK,
ACTIVE_MARK_P): Update.
(_cpp_get_define_token): New internal function.
* cppfiles.c (read_include_file): Don't set fp->alimit or fp->colno.

field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.

token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,

(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.

to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

cpplib.h (struct cpp_name): Now struct cpp_string.
* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

field, a cpp_hashnode *. All references to val.name updated

val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.

return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.

token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.

match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

* cpplex.c (parse_name): No longer inline (premature optimization).
(do_pop_context): Fold into pop_context.
(pop_context): Returns int.
(lex_next): Hoist test for end of directive into pop_context.
(push_macro_context): Returns int; takes just reader and token.
Hoist test for excessive nesting to caller.
(push_arg_context): Returns void; takes just reader and token.

(cpp_get_token): Split out core into _cpp_get_token. Call
process_directive here. Throw away CPP_PLACEMARKER tokens.
(_cpp_get_token): Convert tail recursion through
push_macro_context to a loop at this level.
(_cpp_glue_header_name, is_macro_disabled, stringify_arg,
_cpp_get_raw_token): Use _cpp_get_token.

to push a buffer while macro expansions are stacked.
2000-07-11 Donn Terry <donnte@microsoft.com>
* cpplex.c (free_macro_args, save_token): Cast arg of free
and/or xrealloc to PTR.

* scan-decls.c (skip_to_closing_brace, scan_decls): Update for
new scheme.
* scan.h: Declare struct cpp_token. Update prototypes.

(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.

return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.

node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.

CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.

return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.

* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.

(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.

cpplib.h (struct cpp_name): Now struct cpp_string.
* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.

return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.
(cpp_idcmp): Now cpp_ideq; take a token * and a const char *;
return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.
* fix-header.c, scan-decls.c: Update for interface changes.

* cpplex.c (parse_name): No longer inline (premature optimization).
(do_pop_context): Fold into pop_context.
(pop_context): Returns int.
(lex_next): Hoist test for end of directive into pop_context.
(push_macro_context): Returns int; takes just reader and token.
Hoist test for excessive nesting to caller.
(push_arg_context): Returns void; takes just reader and token.
Do not call stringify_arg or get_raw_token.
(get_raw_token): Convert tail recursion through push_arg_context
to a loop at this level. Call stringify_arg here if appropriate.
(maybe_paste_with_next): Convert tail recursion to a while loop.
Hoist test of paste_level to caller.
(stringify_arg): Push arg context at beginning.
(cpp_get_token): Split out core into _cpp_get_token. Call
process_directive here. Throw away CPP_PLACEMARKER tokens.
(_cpp_get_token): Convert tail recursion through
push_macro_context to a loop at this level.
(_cpp_glue_header_name, is_macro_disabled, stringify_arg,
_cpp_get_raw_token): Use _cpp_get_token.
(_cpp_skip_rest_of_line): Drop the context stack directly; do
not call pop_context.
(_cpp_run_directive): Call lex_next directly.
* cpphash.h: Prototype _cpp_get_token.
* cppexp.c (lex): Use it.

read_line_number, do_line, do_ident, do_pragma, do_pragma_gcc,
do_pragma_implementation, do_pragma_poison, do_pragma_dependency,
parse_ifdef, validate_else): Use it.
(cpp_push_buffer): Tweak error message; abort if anyone tries
to push a buffer while macro expansions are stacked.
2000-07-11 Donn Terry <donnte@microsoft.com>
* cpplex.c (free_macro_args, save_token): Cast arg of free
and/or xrealloc to PTR.
(_cpp_init_input_buffer): Clear all fields of the base context.

field, a cpp_hashnode *. All references to val.name updated

val.str. All references to 'spelling > SPELL_NONE' updated to
match.

field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.

cpplib.h (struct cpp_name): Now struct cpp_string.
* cpplib.h (struct cpp_name): Now struct cpp_string.
(CPP_INT, CPP_FLOAT, CPP_NUMBER, CPP_COMMENT,
CPP_HEADER_NAME): Change to type S.
(struct cpp_token): Rename 'name' field to 'str'. Add 'node'
field, a cpp_hashnode *. All references to val.name updated
to use val.str or val.node as appropriate.
(struct cpp_reader): Add spec_nodes field.
(cpp_idcmp): Now cpp_ideq; takes a token * and a char *.
* cpphash.h (struct spec_nodes): New.
(enum spell_type): Reorder. Only SPELL_STRING tokens use
val.str. All references to 'spelling > SPELL_NONE' updated to
match.
(CPP_IN_SYSTEM_HEADER): Check pfile->buffer and
pfile->buffer->inc are not NULL before dereferencing them.
* cpplex.c (parse_name): Take a pointer to the current token,
plus current position and limit as args; return the new
position; don't copy the text of a name into the string
buffer, instead call cpp_lookup and store the node pointer.
If extending a token, copy out the text of the old into a
scratch buffer, append the new, look that up and store the new
node pointer. Inline.
(maybe_paste_with_next): If the result of paste is a NAME,
then look up the pasted text and store its node pointer.
(lex_line): Adjust for new parse_name interface.
Check for L"str", L'str' using spec_nodes->n_L.
(spell_token): SPELL_IDENT tokens have their spelling in
val.node->name. Handle SPELL_STRING tokens that don't have
string delimiters.
(_cpp_expand_name_space,
(can_paste): Check for L ## "str" using spec_nodes->n_L.
(cpp_get_token, special_symbol): No need to call cpp_lookup.

return 1=equal 0=not, not a tristate.
* cpphash.c (var_args_str): Delete.
(find_param): Compare node fields directly.
(is__va_args__): Use CPP_PEDANTIC. Just compare
token->val.node with spec_nodes->n__VA_ARGS__.
(dump_funlike_macro): Don't use var_args_str.
* cpplib.c (_cpp_check_directive): Just walk through
spec_nodes->dirs comparing pointers.
(get_define_node, do_pragma_poison, detect_if_not_defined,
parse_ifdef): The identifier has already been looked up.
(do_ifdef, do_ifndef): parse_ifdef won't return a poisoned
node.
(do_if): Only call detect_if_not_defined at beginning of file.
(_cpp_parse_assertion): Only copy string pointers for
SPELL_STRING tokens.
(pragma_dispatch): Take a node pointer and examine its name
field.
(_cpp_init_stacks): Also initialize the spec_nodes structure.
* cppinit.c (cpp_reader_init): Call _cpp_init_stacks after
_cpp_init_macros.
(cpp_cleanup): Free pfile->spec_nodes. Call _cpp_cleanup_* in
reverse order from the corresponding _cpp_init_* routines.
* cppexp.c (parse_number, parse_charconst, parse_defined,
lex): Check val.node->type instead of calling cpp_defined.
Use spec_nodes entries where appropriate.

* cpplex.c (parse_name): No longer inline (premature optimization).
(do_pop_context): Fold into pop_context.
(pop_context): Returns int.
(lex_next): Hoist test for end of directive into pop_context.
(push_macro_context): Returns int; takes just reader and token.
Hoist test for excessive nesting to caller.
(push_arg_context): Returns void; takes just reader and token.
Do not call stringify_arg or get_raw_token.
(get_raw_token): Convert tail recursion through push_arg_context
to a loop at this level. Call stringify_arg here if appropriate.
(maybe_paste_with_next): Convert tail recursion to a while loop.
Hoist test of paste_level to caller.
(stringify_arg): Push arg context at beginning.
(cpp_get_token): Split out core into _cpp_get_token. Call
process_directive here. Throw away CPP_PLACEMARKER tokens.
(_cpp_get_token): Convert tail recursion through
push_macro_context to a loop at this level.
(_cpp_glue_header_name, is_macro_disabled, stringify_arg,
_cpp_get_raw_token): Use _cpp_get_token.
(_cpp_skip_rest_of_line): Drop the context stack directly; do
not call pop_context.
(_cpp_run_directive): Call lex_next directly.
* cpphash.h: Prototype _cpp_get_token.

parse_ifdef, validate_else): Use it.
(cpp_push_buffer): Tweak error message; abort if anyone tries
to push a buffer while macro expansions are stacked.
2000-07-11 Donn Terry <donnte@microsoft.com>
* cpplex.c (free_macro_args, save_token): Cast arg of free
and/or xrealloc to PTR.
(_cpp_init_input_buffer): Clear all fields of the base context.
