2000-07-08cpplib.h (struct cpp_name): Now struct cpp_string.Zack Weinberg1-34/+24
* 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. From-SVN: r34926
2000-07-08cpphash.c (is__va_args__): New function.Neil Booth1-29/+56
* cpphash.c (is__va_args__): New function. (count_params): Fix line reported in error messages. Use is__va_args__. Don't return ')' on error. Flag GNU style rest args macro definitions. (parse_define): Check macro name is not __VA_ARGS__. (save_expansion): Check identifier in non-varargs-macro is not __VA_ARGS__. Don't flag GNU_VARARGS. * cpplex.c (parse_args): Accept no argument iff GNU_REST_ARGS. (maybe_paste_with_next): Use per-macro GNU_REST_ARGS rather than per-token GNU_VARARGS. * cpplib.h (GNU_VARARGS): Remove. (GNU_REST_ARGS): New. * gcc.dg/cpp/macsyntx.c: New tests. From-SVN: r34919
