[gcc/objc/ChangeLog]
2004-12-15 Ziemowit Laski <zlaski@apple.com>
* objc-act.c (build_private_template): Change to return 'void'; do
not set ivar_context, uprivate_record or objc_instance_type.
(objc_comptypes, gen_type_name_0): For types 'id' and 'Class',
retrieve protocol list from the pointee rather than the pointer itself;
check TYPE_HAS_OBJC_INFO(...) precondition before accessing
TYPE_OBJC_PROTOCOL_LIST.
(objc_get_protocol_qualified_type): For types 'id' and 'Class',
construct a variant of the pointee as well as the pointer, and
store protocol information in the former. When creating variants
of RECORD_TYPEs, clone their TYPE_LANG_SPECIFIC fields and propagate
TYPE_OBJC_INTERFACE information.
(objc_declare_class): If a TYPE_DECL is looked up, retrieve the
underlying RECORD_TYPE to check for presence of TYPE_OBJC_INTERFACE;
for newly-created RECORD_TYPEs, create a tentative TYPE_OBJC_INTERFACE
holding an IDENTIFIER_NODE.
(objc_finish_message_expr): Check TYPE_HAS_OBJC_INFO(...) before
accessing TYPE_OBJC_PROTOCOL_LIST; Use TYPE_OBJC_INTERFACE instead
of calling lookup_interface(); allow for TYPE_OBJC_INTERFACE holding
an IDENTIFIER_NODE (meaning a @class forward-declaration only).
(objc_is_public): Check TYPE_OBJC_INTERFACE instead of calling
lookup_interface().
(continue_class): For @implementations, set ivar_context,
uprivate_record and objc_instance_type, for @interfaces, call
build_private_template().
(encode_pointer): Check TYPE_HAS_OBJC_INFO(...) before accessing
TYPE_OBJC_INTERFACE.
(objc_types_are_equivalent): Check TYPE_HAS_OBJC_INFO(...) before
accessing TYPE_OBJC_PROTOCOL_LIST.
* objc-act.h (OBJC_INFO_SLOT_ELTS, TYPE_OBJC_INFO, INIT_TYPE_OBJC_INFO,
DUP_TYPE_OBJC_INFO, ALLOC_OBJC_TYPE_LANG_SPECIFIC,
SIZEOF_OBJC_TYPE_LANG_SPECIFIC): New macros.
(TYPE_OBJC_INTERFACE): Replaces TREE_STATIC_INSTANCE and now points
to an actual @interface; stored in TYPE_LANG_SPECIFIC(...).
(TYPE_OBJC_PROTOCOL_LIST): Replaces TYPE_PROTOCOL_LIST; stored in
TYPE_LANG_SPECIFIC(...).
(TREE_STATIC_INSTANCE, TYPE_PROTOCOL_LIST): Delete.
(IS_ID, IS_CLASS, IS_PROTOCOL_QUALIFIED_UNTYPED, IS_SUPER,
TYPED_OBJECT): Check for POINTER_TYPE rather than POINTER_TYPE_P;
adjust for use of TYPE_OBJC_INTERFACE and TYPE_OBJC_PROTOCOL_LIST
instead of TREE_STATIC_INSTANCE and TYPE_PROTOCOL_LIST.
