2010-11-25  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (objc_build_struct): Install TYPE_OBJC_INTERFACE
	after finish_struct, not before, otherwise it may be wiped out by

	class is deprecated.
	(start_class): Added 'attributes' argument.  Emit a warning if
	using a deprecated class as superclass of a class, or original
	class of a category.  Recognize the 'deprecated' attribute when
	starting and interface, and mark the interface with
	TREE_DEPRECATED if present.  Store attributes in the interface.
	
2010-11-19  Nicola Pero  <nicola.pero@meta-innovation.com>

	statement.
	(objc_build_incr_expr_for_property_ref): Updated calls to
	objc_maybe_build_modify_expr to call objc_build_setter_call
	instead.  Use build_modify_expr () instead of build2 (MODIFY_EXPR,
	...).  Use convert () instead of build1 (NOP_EXPR, ...).  Use
	TREE_NO_WARNING on the final compound statement to silence C++
	warnings.

2010-11-15  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (objc_build_incr_expr_for_property_ref): New.
	(objc_create_temporary_var): Moved it towards the beginning of the

2010-11-14  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (objc_add_property_declaration): Check that the decl
	we received from the parser is a FIELD_DECL; reject array and
	bitfield properties.  Convert the warning when a property is
	readonly and a setter is specified into an error.  Convert errors
	when a property declaration does not match a property declaration
	in a superclass into warnings.
	(objc_add_synthesize_declaration_for_property): Use
	DECL_BIT_FIELD_TYPE to determine the type of an instance variable
	if it is a bitfield.  Throw an error if we are asked to synthesize
	setters/getters for a bitfield instance variable but the property
	is not appropriate - it must be assign and nonatomic.  If the
	property is readonly, allow the instance variable type to be a
	specialization of the property type.
	(objc_type_valid_for_messaging): Fixed returning 'false' for a
	Class qualified with a protocol when the 'accept_classes' argument
	is 'false'.

2010-11-13  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (objc_get_protocol_qualified_type): detect cases
	where we are asked to attach a protocol to something which is not

	* objc-act.c (objc_add_property_declaration): Check that the type
	of a property and of an inherited property match.
	(objc_maybe_build_component_ref): Tidied up indentation and
	comments.
	(objc_common_type): Added new type of check (-5).
	(objc_add_synthesize_declaration_for_property): Check that the
	property to synthesize and the instance variable to use have the
	same type.
	
2010-11-10  Joseph Myers  <joseph@codesourcery.com>

	* objc-act.c (objc_init): Use %' in diagnostic.

	* objc-act.c (objc_add_dynamic_declaration_for_property): Do not
	search for the @property declation only in the current context,
	but also in inherited properties.  Do not mark the original
	PROPERTY_DECL in the @interface or @protocol with
	PROPERTY_DYNAMIC.
	(check_methods): To check if a method is associated with a
	@dynamic property, search for the property in IMPL_PROPERTY_DECL.
	(check_accessible_methods): Same change.
	* objc-act.h: Updated comment.

2010-11-08  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (objc_add_synthesize_declaration_for_property):
	Iterate over IMPL_PROPERTY_DECL, not CLASS_PROPERTY_DECL, when
	checking for an existing @synthesize or @dynamic declaration.
	Search for an inherited @property declaration if none is found in
	the local interface.  If the required instance variable does not
	exist, return instead of trying to continue to prevent a compiler
	crash later.  Check that the instance variable is not already
	being used by another @synthesize.
	(objc_add_dynamic_declaration_for_property): Iterate over
	IMPL_PROPERTY_DECL, not CLASS_PROPERTY_DECL, when checking for an
	existing @synthesize or @dynamic declaration.
	(objc_synthesize_getter): Search for the getter declaration in
	protocols and superclasses as well.
	(objc_synthesize_setter): Search for the setter declaration in
	protocols and superclasses as well.
	
2010-11-08  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (lookup_property): When checking categories, also
	check the protocols attached to each.
	(objc_add_property_declaration): Determine the
	PROPERTY_SETTER_NAME and PROPERTY_GETTER_NAME here.  Tidied up
	error message.  Search for an existing property declaration with
	the same name which would be inherited from the class hiearchy,
	and produce an error if it has incompatible attributes.
	(check_methods): Changed second parameter.  If the method is a
	getter or setter for a property, do not warn if it is inherited as
	opposed to implemented directly in the class.
	(check_protocol): Updated calls to check_methods.
	(finish_class): Do not determine the PROPERTY_SETTER_NAME and
	PROPERTY_GETTER_NAME here; this is now done earlier, in
	objc_add_property_declaration.
	* objc-act.h (CLASS_NAME, CLASS_SUPER_NAME): Added comments.
	
2010-11-06  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (OBJC_LOOKUP_NO_INSTANCE_METHODS_OF_ROOT_CLASS): New.
	(maybe_make_artificial_property_decl): Added 'implementation'
	argument.  Use OBJC_LOOKUP_NO_INSTANCE_METHODS_OF_ROOT_CLASS when
	looking up getters or setters for a class.  If an implementation
	is specified, search it as well for a getter or setter.
	(objc_maybe_build_component_ref): Updated calls to
	maybe_make_artificial_property_decl; added code to deal with
	'self' and 'super' and with methods declared locally in the
	implementation.  Store the getter call expression in the
	PROPERTY_REF instead of throwing it away.
	(objc_build_class_component_ref): Updated calls to
	maybe_make_artificial_property_decl, and store the getter call
	expression in PROPERTY_REF instead of throwing it away.
	(lookup_method_static): Implemented
	OBJC_LOOKUP_NO_INSTANCE_METHODS_OF_ROOT_CLASS option.
	(objc_gimplify_property_ref): Do not build the getter method call
	here; instead use the one stored in the PROPERTY_REF.  If it's not
	there, produce helpful error messages.

	from 2 to 3.  Updated comments.
	* objc-act.h (PROPERTY_REF_GETTER_CALL): New.

	more than on pointer indirection.
	(objc_add_property_declaration): Only warn about 'assign'
	semantics for Objective-C objects if warn_property_assign_default;
	and do not warn if the property is readonly or if the type is a Class.

	warnings if the receiver is of type 'id'.
	(really_start_method): Install 'deprecation' and 'noreturn'
	attributes.
	(objc_decl_method_attributes): Carefully filter out the list of
	attributes, allowing only "noreturn", "format", "sentinel" and
	"deprecated".  In the case of "format", adjust the arguments.
	Always process the attributes in the same way no matter if
	"sentinel" is in the list or not.
	
2010-11-01  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (objc_maybe_build_component_ref): Warn about using

	and code supporting them.  Fixed recovering when readonly and
	setter attributes are specified.  Removed support for @property in
	@implementation context.  Updated error message.  Double-check
	that a property does not have a DECL_INITIAL.  Validate the
	property assign semantics and emit appropriate errors and

	DECL_SOURCE_LOCATION, TREE_DEPRECATED, PROPERTY_NONATOMIC,
	PROPERTY_ASSIGN_SEMANTICS and PROPERTY_DYNAMIC of the new
	PROPERTY_DECL.  Do not set PROPERTY_COPIES.  Set
	PROPERTY_IVAR_NAME to NULL_TREE.
	(objc_build_getter_call): Renamed to
	objc_maybe_build_component_ref.  If the property is not found in

	(objc_finish_message_expr): Removed check to produce "readonly
	property can not be set" error when
	in_objc_property_setter_name_context.  We now generate the error

	is instead of trying to guess what it should be.  Removed use of
	CLASS_IVARS.  Use the location of @synthesize for c_finish_return

	expected argument.
	(objc_add_synthesize_declaration_for_property): New.
	(objc_add_synthesize_declaration): Removed ATTRIBUTE_UNUSED from

	(finish_class): Added explicit switch cases for
	CLASS_INTERFACE_TYPE, CATEGORY_INTERFACE_TYPE and
	PROTOCOL_INTERFACE_TYPE.  Added a default switch case which is
	gcc_unreachable.  Rewritten the processing of properties, in
	particular to not synthesize prototypes for getters and setters if
	they already exist and to install the getter and setter names into
	PROPERTY_GETTER_NAME and PROPERTY_SETTER_NAME.  Do not generate
	warnings about setter, getter and ivar property attributes.
	(objc_lookup_ivar): Removed support for properties.
	(objc_gimplify_property_ref): New.
	(objc_gimplify_expr): Use a switch.  In case of a PROPERTY_REF, call

	* objc-act.c (objc_add_property_declaration): Added arguments to
	pass the various property attributes that were parsed with the
	property declaration.  Process arguments to determine the final
	property attributes and produce error messages as appropriate.
	Added temporary code to keep the compiler silent about variables
	set but not used - for new attributes that are only checked but
	have no effect yet.
	(property_readonly): Removed.
	(property_setter): Removed.

	implementation context.
	
2010-10-24  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (objc_build_keyword_decl): Updated comments.  Do not

	the corresponding PARM_DECL.
	(objc_warn_deprecated_use): Removed.
	(build_objc_method_call): Call warn_deprecated_use, not

	longer used.  Updated comments.
	
2010-10-23  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (OBJC_GEN_METHOD_LABEL): Updated comments.
	(objc_demangle): Return NULL if demangling can not be done because
	the string to demangle is not an Objective-C mangled method name.
	Be smarter in demangling method names so that at least for methods
	with no arguments we are able to almost always demangle '_' correctly.
	Updated comments.
	(objc_maybe_printable_name): New.
