2011-10-25Introduce a placeholder type for "pseudo object"John McCall
expressions: expressions which refer to a logical rather than a physical l-value, where the logical object is actually accessed via custom getter/setter code. A subsequent patch will generalize the AST for these so that arbitrary "implementing" sub-expressions can be provided. Right now the only client is ObjC properties, but this should be generalizable to similar language features, e.g. Managed C++'s __property methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142914 91177308-0d34-0410-b5e6-96231b3b80d8

But we should _not_ emit an error for the following cases, because we can get the ownership either from the declared ivar or from the property type: @interface Foo : NSObject { __weak id _myProp1; id myProp2; } @property (readonly) id myProp1; @property (readonly) id myProp2; @property (readonly) __strong id myProp3; @end @implementation Foo @synthesize myProp1 = _myProp1; @synthesize myProp2; @synthesize myProp3; @end  rdar://9844006. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136155 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-12[ARC] Complain about property without storage attribute when @synthesizing ↵Argyrios Kyrtzidis
it, not at its declaration. For this sample: @interface Foo @property id x; @end we get: t.m:2:1: error: ARC forbids properties of Objective-C objects with unspecified storage attribute @property id x; ^ 1 error generated. The error should be imposed on the implementor of the interface, not the user. If the user uses a header of a non-ARC library whose source code he does not have, we are basically asking him to go change the header of the library (bad in general), possible overriding how the property is implemented if he gets confused and says "Oh I'll just add 'copy' then" (even worse). Second issue is that we don't emit any error for 'readonly' properties, e.g: @interface Foo @property (readonly) id x; // no error here @end @implementation Foo @synthesize x; // no error here too @end We should give an error when the implementor is @synthesizing a property which doesn't have any storage specifier; this is when the explicit specifier is important, because we are going to create an ivar and we want its ownership to be explicit. Related improvements: -OBJC_PR_unsafe_unretained turned out to not fit in ObjCPropertyDecl's bitfields, fix it. -For properties of extension classes don't drop PropertyAttributesAsWritten values. -Have PropertyAttributesAsWritten actually only reflect what the user wrote rdar://9756610. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134960 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-06Change the driver's logic about Objective-C runtimes: abstract out aJohn McCall
structure to hold inferred information, then propagate each invididual bit down to -cc1. Separate the bits of "supports weak" and "has a native ARC runtime"; make the latter a CodeGenOption. The tool chain is still driving this decision, because it's the place that has the required deployment target information on Darwin, but at least it's better-factored now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134453 91177308-0d34-0410-b5e6-96231b3b80d8
