	protocols.

2010-12-30  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (objc_add_method): When emitting an error because a
	method with the same name but conflicting types is found in the
	same class or category interface, print a note with the location
	of the original method.  Also, improved the error message to
	clearly state that the conflict is due to conflicting types, and
	produce it for protocols as well.  Emit an error if two identical
	methods are declared in a protocol, but one is @required and the
	other one is @optional.

2010-12-30  Nicola Pero  <nicola.pero@meta-innovation.com>

	* objc-act.c (start_class): Warn when a class attribute is

	PR objc/47118
	* objc-act.c (objc_build_synchronized): Check the argument of

	allowing to return the deprecated method prototype for deprecated
	methods, instead of immediately emitting the deprecation warning.
	(objc_maybe_build_component_ref): Do not warn for a deprecated
	property.  When building the getter call, get the deprecated
	method prototype from objc_finish_message_expr() and put it into

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

	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'.

2010-11-08  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.

	(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

2010-10-30  Nicola Pero  <nicola.pero@meta-innovation.com>

	Implemented Objective-C 2.0 @property, @synthesize and @dynamic.
	* objc-tree.def (PROPERTY_REF): New.
	* objc-act.h: Added comments for all the PROPERTY_ macros.
	(PROPERTY_NAME): Use DECL_NAME.
	(PROPERTY_COPIES): Removed.
	(PROPERTY_READONLY): Use DECL_LANG_FLAG_0 for it.
	(PROPERTY_NONATOMIC): New.
	(objc_property_assign_semantics): Make it a typedef.
	(PROPERTY_ASSIGN_SEMANTICS): New.
	(PROPERTY_DYNAMIC): New.
	(PROPERTY_REF_OBJECT): New.
	(PROPERTY_REF_PROPERTY_DECL): New.
	* objc-act.c (CALL_EXPR_OBJC_PROPERTY_GETTER): Removed.
	(in_objc_property_setter_name_context): Removed.
	(objc_add_property_declaration): Removed copies and ivar arguments
	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
	warnings.  Check for duplicate property declarations.  Set
	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
	the interface, search in the protocol list.  Do not generate the
	getter call; instead, build and return a PROPERTY_REF.
	(objc_is_property_ref): New.
	(objc_setter_func_call): Removed.
	(get_selector_from_reference): Removed.
	(is_property): Removed.
	(objc_build_setter_call): Renamed to objc_maybe_build_modify_expr.
	Updated to work on a PROPERTY_REF and use the PROPERTY_DECL from
	the PROPERTY_REF.  Generate an error if the property is read-only.
	(build_property_reference): Removed.
	(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
	earlier, in objc_maybe_build_modify_expr, which will only generate
	the setter call if the property is readwrite.
	(check_methods): Recognize dynamic properties.
	(check_methods_accessible): Same change.
	(objc_build_property_ivar_name): Removed.
	(objc_build_property_setter_name): Dropped bool argument.  Always
	add the ':' at the end.
	(objc_gen_one_property_datum): Removed.
	(objc_process_getter_setter): Removed.
	(objc_synthesize_getter): Mark 'klass' argument as unused.  Use
	PROPERTY_GETTER_NAME instead of PROPERTY_NAME.  Set the
	DECL_SOURCE_LOCATION of the new method to be the same as the one
	for the @synthesize.  Always use PROPERTY_IVAR_NAME as it is
	instead of trying to guess what it should be.  Removed use of
	CLASS_IVARS.  Use the location of @synthesize for c_finish_return
	and c_end_compound_statement.
	(objc_synthesize_setter): Mark 'klass' argument as unused.  Use
	PROPERTY_SETTER_NAME instead of trying to guess what it should be.
	Set the DECL_SOURCE_LOCATION of the new method to be the same as
	the one for the @synthesize.  Always use PROPERTY_IVAR_NAME as it
	is instead of trying to guess what it should be.  Removed use of
	CLASS_IVARS.  Use the location of @synthesize for c_finish_return
	and c_end_compound_statement.  Emit an error and keep going,
	instead of aborting, if the setter prototype does not have the
	expected argument.
	(objc_add_synthesize_declaration_for_property): New.
	(objc_add_synthesize_declaration): Removed ATTRIBUTE_UNUSED from
	all arguments.  Improved error message.  Filled in the rest of the
	function, which used to be a placeholder, with an actual
	implementation.
	(objc_add_dynamic_declaration_for_property): New.
	(objc_add_dynamic_declaration): Removed ATTRIBUTE_UNUSED from all
	arguments.  Improved error message.  Filled in the rest of the
	function, which used to be a placeholder, with an actual
	implementation.
	(objc_gen_property_data): Rewritten.
	(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_gimplify_property_ref.

2010-10-27  Nicola Pero  <nicola.pero@meta-innovation.com>

	* 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.

	warnings and errors to use it.  Use error, not fatal_error, if a
	property declaration is found outside an interface or
	implementation context.

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

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

	Instead, store them into DECL_ATTRIBUTES of the KEYWORD_DECL.
	(start_method_def): Copy attributes from each KEYWORD_DECL into
	the corresponding PARM_DECL.
	(objc_warn_deprecated_use): Removed.
	(build_objc_method_call): Call warn_deprecated_use, not
	objc_warn_deprecated_use.
	(objc_maybe_printable_name): Do not try to get the identifier name
	of DECLs that we don't recognize.  Immediately return NULL for them.
	(objc_printable_name): Removed C++-specific case, which is no
	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.
	(objc_printable_name): Call objc_maybe_printable_name.  If it
	returns NULL, call cxx_printable_name in Objective-C++.
