From c9e266b8cf4abd43167b70609df6039da3ecd9b4 Mon Sep 17 00:00:00 2001 From: Fariborz Jahanian Date: Thu, 11 Dec 2014 22:56:26 +0000 Subject: [Objective-C]. This patch extends objc_bridge attribute to support objc_bridge(id). This means that a pointer to the struct type to which the attribute appertains is a CF type (and therefore an Objective-C object of some type), but not of any specific class. rdar://19157264 llvm-svn: 224072 --- clang/test/SemaObjC/objcbridge-attribute-arc.m | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'clang/test/SemaObjC') diff --git a/clang/test/SemaObjC/objcbridge-attribute-arc.m b/clang/test/SemaObjC/objcbridge-attribute-arc.m index ee2bf07ed47..ab8cab8d191 100644 --- a/clang/test/SemaObjC/objcbridge-attribute-arc.m +++ b/clang/test/SemaObjC/objcbridge-attribute-arc.m @@ -221,3 +221,19 @@ void Test9(CFErrorRef2 cf, NSError *ns, NSString *str, Class c, CFUColor2Ref cf2 (void)(__bridge Class)cf; // expected-warning {{'CFErrorRef2' (aka 'struct __CFErrorRef *') bridges to NSError, not 'Class'}} (void)(__bridge CFErrorRef)c; // expected-warning {{'__unsafe_unretained Class' cannot bridge to 'CFErrorRef' (aka 'struct __CFErrorRef *')}} } + +// rdar://19157264 +#if __has_feature(objc_bridge_id) +typedef struct __attribute__((objc_bridge(id))) __CFFoo *CFFooRef; +#endif + +id convert(CFFooRef obj) { + (void)(NSError *)obj; // expected-error {{cast of C pointer type 'CFFooRef' (aka 'struct __CFFoo *') to Objective-C pointer type 'NSError *' requires a bridged cast}} \ + // expected-note {{use __bridge to convert directly (no change in ownership)}} \ + // expected-note {{use __bridge_transfer to transfer ownership of a +1 'CFFooRef' (aka 'struct __CFFoo *') into ARC}} + (void) (__bridge NSError *)obj; + (void) (id)obj; // expected-error {{cast of C pointer type 'CFFooRef' (aka 'struct __CFFoo *') to Objective-C pointer type 'id' requires a bridged cast}} \ + // expected-note {{use __bridge to convert directly (no change in ownership)}} \ + // expected-note {{use __bridge_transfer to transfer ownership of a +1 'CFFooRef' (aka 'struct __CFFoo *') into ARC}} + return (__bridge id)obj; +} -- cgit v1.2.3
