From d4e72c58e36abe902834d122b291a91debd5625c Mon Sep 17 00:00:00 2001 From: Nicola Pero Date: Fri, 19 Nov 2010 22:23:22 +0000 Subject: In gcc/objc/: 2010-11-19 Nicola Pero In gcc/objc/: 2010-11-19 Nicola Pero * objc-act.c (objc_start_class_interface): Do not warn that class attributes are unimplemented. Pass the attributes to start_class. (objc_start_category_interface): Updated call to start_class. (objc_start_class_implementation): Same change. (objc_start_category_implementation): Same change. (objc_build_class_component_ref): Warn if the class is deprecated. (build_private_template): Mark the template as deprecated if the 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. In gcc/testsuite/: 2010-11-19 Nicola Pero * objc.dg/attributes/class-attribute-1.m: Rewritten. * objc.dg/attributes/class-attribute-2.m: Same change. * obj-c++.dg/attributes/class-attribute-1.mm: Same change. * obj-c++.dg/attributes/class-attribute-2.mm: Same change. * objc.dg/fobjc-std-1.m: Updated. * obj-c++.dg/fobjc-std-1.mm: Updated.
