2004-12-15  Ziemowit Laski  <[e-mail]>

	* 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.

	* objc-act.c (objc_lookup_ivar): The new OTHER parameter
	contains the result of the ID lookup by the C or C++
	front-end; in class methods, use OTHER if it exists;
	in instance methods, use OTHER only if it is locally
	declared.

2004-10-26  Ziemowit Laski  <[e-mail]>

	* objc-act.c (finish_class): Do not synthesize bogus
	'extern objc_object *_Foo;' declarations for @interface Foo.

	    David Ayers  <[e-mail]>

	* objc-act.c (objc_comptypes): Use IS_PROTOCOL_QUALIFIED_UNTYPED
	instead of IS_PROTOCOL_QUALIFIED_ID; add comparisons for:
	'Class <Protocol> != id <Protocol>'; 'Class <Protocol> != <class> *';
	'Class <Protocol> == id' and 'Class <Protocol> == Class'.
	(objc_is_id): Add test for 'super'.
	(objc_finish_message_expr): Allow for messaging of 'Class <Proto>'
	receivers; if class methods are not found in protocol lists, search
	for instance methods therein and warn if one is found.  Look in
	global hash tables for suitable method as a last resort when messaging
	'id <Proto>', 'Class <Proto>' and invalid receiver types.
	(objc_add_method): Insert instance methods listed in protocols into
	the global class method hash table.
	* objc-act.h (IS_PROTOCOL_QUALIFIED_ID): Rename to
	IS_PROTOCOL_QUALIFIED_UNTYPED and allow for 'Class <Proto>' in
	addition to 'id <Proto>'.

	throughout.
	(objc_init): Only set input_line to 0 #ifndef USE_MAPPED_LOCATION.
