2011-11-25In Microsoft mode, make "Unqualified lookup into dependent bases of class ↵Francois Pichet
templates" works inside a friend function definition at class scope. Basically we have to look into the parent *lexical* DeclContext for friend functions at class scope. That's because calling GetParent() return the namespace or file DeclContext. This fixes all remaining cases of "Unqualified lookup into dependent bases of class templates" when parsing MFC code with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145127 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-23Add feature to diagnostics that will provide more information on functionRichard Trieu
pointer mismatch. Cases covered are: initialization, assignment, and function arguments. Additional text will give the extra information about the nature of the mismatch: different classes for member functions, wrong number of parameters, different parameter type, different return type, and function qualifier mismatch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145114 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-17In Microsoft mode, make "Unqualified lookup into dependent bases of class ↵Francois Pichet
templates" works inside default argument instantiation. This is a little bit tricky because during default argument instantiation the CurContext points to a CXXMethodDecl but we can't use the keyword this or have an implicit member call generated. This fixes 2 errors when parsing MFC code with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144881 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-10There's no good reason to track temporaries in ExprWithCleanups,John McCall

2011-11-06Change the AST representation of operations on Objective-CJohn McCall
property references to use a new PseudoObjectExpr expression which pairs a syntactic form of the expression with a set of semantic expressions implementing it. This should significantly reduce the complexity required elsewhere in the compiler to deal with these kinds of expressions (e.g. IR generation's special l-value kind, the static analyzer's Message abstraction), at the lower cost of specifically dealing with the odd AST structure of these expressions. It should also greatly simplify efforts to implement similar language features in the future, most notably Managed C++'s properties and indexed properties. Most of the effort here is in dealing with the various clients of the AST. I've gone ahead and simplified the ObjC rewriter's use of properties; other clients, like IR-gen and the static analyzer, have all the old complexity *and* all the new complexity, at least temporarily. Many thanks to Ted for writing and advising on the necessary changes to the static analyzer. I've xfailed a small diagnostics regression in the static analyzer at Ted's request. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143867 91177308-0d34-0410-b5e6-96231b3b80d8

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

2011-10-17The comparison of two vectors should return a signed result. ↵Tanya Lattner
hasIntegerRepresentation() used to always return false for vectors, but since it was changed, it also changed the return type of a compare of two unsigned vectors to be unsigned. This patch removes the check for hasIntegerRepresentation since its not needed and returns the appropriate signed type. I added a new test case and updated exisiting test cases that assumed an unsigned result. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142250 91177308-0d34-0410-b5e6-96231b3b80d8
