* 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.
