+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.

+ 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++.
