* [ObjC] Check that a subscript methods is declared for a qualified id typeAlex Lorenz2017-07-111-7/+2
| | | | | | | | | | | | | Objective-C subscript expressions report errors when a subscript method is not declared in the base class. However, prior to this commit, qualified id types were not checked. This commit ensures that an appropriate error is reported when a subscript method is not declared in any of the protocols that are included in the qualified id type. rdar://33213924 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@307642 91177308-0d34-0410-b5e6-96231b3b80d8

* Encapsulate FPOptions and use it consistentlyAdam Nemet2017-03-271-5/+8
| | | | | | | | | | | | | | | | | | Sema holds the current FPOptions which is adjusted by 'pragma STDC FP_CONTRACT'. This then gets propagated into expression nodes as they are built. This encapsulates FPOptions so that this propagation happens opaquely rather than directly with the fp_contractable on/off bit. This allows controlled transitioning of fp_contractable to a ternary value (off, on, fast). It will also allow adding more fast-math flags later. This is toward moving fp-contraction=fast from an LLVM TargetOption to a FastMathFlag in order to fix PR25721.

* arc-repeated-use-of-weak should not warn about IBOutlet propertiesBob Wilson2016-05-251-1/+1
| | | | | | | | | | | | | | Revision r211132 was supposed to disable -Warc-repeated-use-of-weak for Objective-C properties marked with the IBOutlet attribute. Those properties are supposed to be weak but they are only accessed from the main thread so there is no risk of asynchronous updates setting them to nil. That combination makes -Warc-repeated-use-of-weak very noisy. The previous change only handled one kind of access to weak IBOutlet properties. Instead of trying to add checks for all the different kinds of property accesses, this patch removes the previous special case check and adds a check at the point where the diagnostic is reported. rdar://21366461 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@270665 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | MSVC supports 'property' attribute and allows to apply it to the declaration of an empty array in a class or structure definition. For example: ``` __declspec(property(get=GetX, put=PutX)) int x[]; ``` The above statement indicates that x[] can be used with one or more array indices. In this case, i=p->x[a][b] will be turned into i=p->GetX(a, b), and p->x[a][b] = i will be turned into p->PutX(a, b, i); Differential Revision: http://reviews.llvm.org/D13336 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@254067 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | a contextually-typed expression that semantic analysis will probably need to invasively rewrite, don't include the RHS OVE as a separate semantic expression, and check the operation with the original RHS expression. There are two contextually-typed expressions that can survive to here: overloaded function references, which are at least safe to double-emit, and C++11 initializer list expressions, which are not at all safe to double-emit and which often don't update the original syntactic InitListExpr with implicit conversions to member types, etc. This means that the original RHS may appear, undecorated by an OVE, in the semantic expressions. Fortunately, it will only ever be used in a single place there, and I don't believe there are clients that rely on being able to pick out the original RHS from the semantic expressions. But this could be problematic if there are clients that do visit the entire tree and rely on not seeing the same expression multiple times, once in the syntactic and once in the semantic expressions. This is a very fiddly part of the compiler. rdar://21801088 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@245771 91177308-0d34-0410-b5e6-96231b3b80d8
* Substitute type arguments into uses of Objective-C interface members.Douglas Gregor2015-07-071-26/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When messaging a method that was defined in an Objective-C class (or category or extension thereof) that has type parameters, substitute the type arguments for those type parameters. Similarly, substitute into property accesses, instance variables, and other references. This includes general infrastructure for substituting the type arguments associated with an ObjCObject(Pointer)Type into a type referenced within a particular context, handling all of the substitutions required to deal with (e.g.) inheritance involving parameterized classes. In cases where no type arguments are available (e.g., because we're messaging via some unspecialized type, id, etc.), we substitute in the type bounds for the type parameters instead. Example: @interface NSSet<T : id<NSCopying>> : NSObject <NSCopying> - (T)firstObject; @end void f(NSSet<NSString *> *stringSet, NSSet *anySet) { [stringSet firstObject]; // produces NSString* [anySet firstObject]; // produces id<NSCopying> (the bound) } When substituting for the type parameters given an unspecialized context (i.e., no specific type arguments were given), substituting the type bounds unconditionally produces type signatures that are too strong compared to the pre-generics signatures. Instead, use the following rule: - In covariant positions, such as method return types, replace type parameters with “id” or “Class” (the latter only when the type parameter bound is “Class” or qualified class, e.g, “Class<NSCopying>”) - In other positions (e.g., parameter types), replace type parameters with their type bounds. - When a specialized Objective-C object or object pointer type contains a type parameter in its type arguments (e.g., NSArray<T>*, but not NSArray<NSString *> *), replace the entire object/object pointer type with its unspecialized version (e.g., NSArray *). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@241543 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | The compilation pipeline doesn't actually need to know about the high-level concept of diagnostic mappings, and hiding the final computed level presents several simplifications and other potential benefits.
