From b642fca1c31b2e2175e0860daf32b4ee0d918085 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Wed, 4 Nov 2020 23:52:12 +0000 Subject: Objective-C/C++ : Handle parsing @property 'class' attribute. This attribute states that a property is one manipulated by class methods (it requires a static variable and the setter and getter must be provided explicitly, they cannot be @synthesized). gcc/c-family/ChangeLog: * c-common.h (OBJC_IS_PATTR_KEYWORD): Add class to the list of keywords accepted in @property attribute contexts. * c-objc.h (enum objc_property_attribute_group): Add OBJC_PROPATTR_GROUP_CLASS. (enum objc_property_attribute_kind): Add OBJC_PROPERTY_ATTR_CLASS. gcc/cp/ChangeLog: * parser.c (cp_parser_objc_at_property_declaration): Handle class keywords in @property attribute context. gcc/objc/ChangeLog: * objc-act.c (objc_prop_attr_kind_for_rid): Handle class attribute. (objc_add_property_declaration): Likewise. * objc-act.h (PROPERTY_CLASS): Record class attribute state. gcc/testsuite/ChangeLog: * obj-c++.dg/property/at-property-4.mm: Test handling class attributes. * objc.dg/property/at-property-4.m: Likewise. --- gcc/objc/objc-act.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'gcc/objc/objc-act.h') diff --git a/gcc/objc/objc-act.h b/gcc/objc/objc-act.h index db71b6a..5b0433f 100644 --- a/gcc/objc/objc-act.h +++ b/gcc/objc/objc-act.h @@ -137,6 +137,10 @@ enum objc_property_assign_semantics { #define PROPERTY_OPTIONAL(DECL) \ DECL_LANG_FLAG_5 (PROPERTY_DECL_CHECK (DECL)) +/* PROPERTY_CLASS can be 0 or 1. */ +#define PROPERTY_CLASS(DECL) \ + DECL_LANG_FLAG_6 (PROPERTY_DECL_CHECK (DECL)) + /* PROPERTY_REF.
