From 6f762481a21f211c03b6eda416b5d5737c3ed4b7 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Mon, 2 Nov 2020 21:12:38 +0000 Subject: [PATCH] Objective-C/C++ (C-family) : Add missing 'atomic' property attribute. This is the default, but it is still legal in user code and therefore we should handle it in parsing. Fix whitespace issues in the lines affected. gcc/c-family/ChangeLog: * c-common.c (c_common_reswords): Add 'atomic' property attribute. * c-common.h (enum rid): Add RID_PROPATOMIC for atomic property attributes. gcc/objc/ChangeLog: * objc-act.c (objc_prop_attr_kind_for_rid): Handle RID_PROPATOMIC. gcc/testsuite/ChangeLog: * obj-c++.dg/property/at-property-4.mm: Test atomic property attribute. * objc.dg/property/at-property-4.m: Likewise. --- gcc/c-family/c-common.c | 17 +++++++++-------- gcc/c-family/c-common.h | 2 +- gcc/objc/objc-act.c | 1 + .../obj-c++.dg/property/at-property-4.mm | 3 +++ gcc/testsuite/objc.dg/property/at-property-4.m | 3 +++ 5 files changed, 17 insertions(+), 9 deletions(-) diff --git a/gcc/c-family/c-common.c b/gcc/c-family/c-common.c index 9302a2461d4..d4d3228b8f6 100644 --- a/gcc/c-family/c-common.c +++ b/gcc/c-family/c-common.c @@ -571,14 +571,15 @@ const struct c_common_resword c_common_reswords[] = { "oneway", RID_ONEWAY, D_OBJC }, { "out", RID_OUT, D_OBJC }, /* These are recognized inside a property attribute list */ - { "assign", RID_ASSIGN, D_OBJC }, - { "copy", RID_COPY, D_OBJC }, - { "getter", RID_GETTER, D_OBJC }, - { "nonatomic", RID_NONATOMIC, D_OBJC }, - { "readonly", RID_READONLY, D_OBJC }, - { "readwrite", RID_READWRITE, D_OBJC }, - { "retain", RID_RETAIN, D_OBJC }, - { "setter", RID_SETTER, D_OBJC }, + { "assign", RID_ASSIGN, D_OBJC }, + { "atomic", RID_PROPATOMIC, D_OBJC }, + { "copy", RID_COPY, D_OBJC }, + { "getter", RID_GETTER, D_OBJC }, + { "nonatomic", RID_NONATOMIC, D_OBJC }, + { "readonly", RID_READONLY, D_OBJC }, + { "readwrite", RID_READWRITE, D_OBJC }, + { "retain", RID_RETAIN, D_OBJC }, + { "setter", RID_SETTER, D_OBJC }, };
