2011-12-15Keep track of all declarations of an Objective-C class (both forwardDouglas Gregor
declarations and definitions) as ObjCInterfaceDecls within the same redeclaration chain. This new representation matches what we do for C/C++ variables/functions/classes/templates/etc., and makes it possible to answer the query "where are all of the declarations of this class?" git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146679 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-15Move the definition-specific data of ObjCInterfaceDecl into aDouglas Gregor
separately-allocated DefinitionData structure, which we manage the same way as CXXRecordDecl::DefinitionData. This prepares the way for making ObjCInterfaceDecls redeclarable, to more accurately model forward declarations of Objective-C classes and eliminate the mutation of ObjCInterfaceDecl that causes us serious trouble in the AST reader. Note that ObjCInterfaceDecl's accessors are fairly robust against being applied to forward declarations, because Clang (and Sema in particular) doesn't perform RequireCompleteType/hasDefinition() checks everywhere it has to. Each of these overly-robust cases is marked with a FIXME, which we can tackle over time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146644 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-03Add a printing policy flag to suppress printing "<anonymous>::" priorDouglas Gregor

2011-04-08Use ExprResult& instead of Expr *& in SemaJohn Wiegley
This patch authored by Eric Niebler. Many methods on the Sema class (e.g. ConvertPropertyForRValue) take Expr pointers as in/out parameters (Expr *&). This is especially true for the routines that apply implicit conversions to nodes in-place. This design is workable only as long as those conversions cannot fail. If they are allowed to fail, they need a way to report their failures. The typical way of doing this in clang is to use an ExprResult, which has an extra bit to signal a valid/invalid state. Returning ExprResult is de riguour elsewhere in the Sema interface. We suggest changing the Expr *& parameters in the Sema interface to ExprResult &. This increases interface consistency and maintainability. This interface change is important for work supporting MS-style C++ properties. For reasons explained here <http://lists.cs.uiuc.edu/pipermail/cfe-dev/2011-February/013180.html>, seemingly trivial operations like rvalue/lvalue conversions that formerly could not fail now can. (The reason is that given the semantics of the feature, getter/setter method lookup cannot happen until the point of use, at which point it may be found that the method does not exist, or it may have the wrong type, or overload resolution may fail, or it may be inaccessible.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129143 91177308-0d34-0410-b5e6-96231b3b80d8
