2009-11-22Fix LookupResult's sanity-check to handle shadow decls.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89624 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-22If a C++ qualified id is followed by a postfix suffix, it is never the directJohn McCall
operand of an addressof operator, and so we should not treat it as an abstract member-pointer expression and therefore suppress the implicit member access. This is really a well-formedness constraint on expressions: a DeclRefExpr of a FieldDecl or a non-static CXXMethodDecl (or template thereof, or unresolved collection thereof) should not be allowed in an arbitrary location in the AST. Arguably it shouldn't be allowed anywhere and we should have a different expr node type for this. But unfortunately we don't have a good way of enforcing this kind of constraint right now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89578 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-21This patch implements objective-c's 'SEL' type as a built-inFariborz Jahanian
type and fixes a long-standing code gen. crash reported in at least two PRs and a radar. (radar 7405040 and pr5025). There are couple of remaining issues that I would like for Ted. and Doug to look at: Ted, please look at failure in Analysis/MissingDealloc.m. I have temporarily added an expected-warning to make the test pass. This tests has a declaration of 'SEL' type which may not co-exist with the new changes. Doug, please look at a FIXME in PCHWriter.cpp/PCHReader.cpp. I think the changes which I have ifdef'ed out are correct. They need be considered for in a few Indexer/PCH test cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89561 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-21Overload resolution doesn't decide whether to do ADL or not anymore; stoppingJohn McCall
threading that state. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89557 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-21"Incremental" progress on using expressions, by which I mean totally rippingJohn McCall
into pretty much everything about overload resolution in order to wean BuildDeclarationNameExpr off LookupResult::getAsSingleDecl(). Replace UnresolvedFunctionNameExpr with UnresolvedLookupExpr, which generalizes the idea of a non-member lookup that we haven't totally resolved yet, whether by overloading, argument-dependent lookup, or (eventually) the presence of a function template in the lookup results. Incidentally fixes a problem with argument-dependent lookup where we were still performing ADL even when the lookup results contained something from a block scope. Incidentally improves a diagnostic when using an ObjC ivar from a class method. This just fell out from rewriting BuildDeclarationNameExpr's interaction with lookup, and I'm too apathetic to break it out. The only remaining uses of OverloadedFunctionDecl that I know of are in TemplateName and MemberExpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89544 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-21Added rudimentary C++0x attribute support.Sean Hunt
The following attributes are currently supported in C++0x attribute lists (and in GNU ones as well): - align() - semantics believed to be conformant to n3000, except for redeclarations and what entities it may apply to - final - semantics believed to be conformant to CWG issue 817's proposed wording, except for redeclarations - noreturn - semantics believed to be conformant to n3000, except for redeclarations - carries_dependency - currently ignored (this is an optimization hint) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89543 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-20Implement C++ [basic.lookup.classref]p3, which states how the typeDouglas Gregor
name 'T' is looked up in the expression t.~T() Previously, we weren't looking into the type of "t", and therefore would fail when T actually referred to an injected-class-name. Fixes PR5530. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89493 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-20When we have a non-dependent expression such asDouglas Gregor
A::f that occurs within a non-static member function with a type-dependent "this", don't consider this to be a case for introduction of an implicit "(*this)." to refer to a specific member function unless we know (at template definition time) that A is a base class of *this. There is some disagreement here between GCC, EDG, and Clang about the handling of this case. I believe that Clang now has the correct, literal interpretation of the standard, but have asked for clarification (c++std-core-15483). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89425 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-19Draw a brighter line between "unresolved" expressions, where we have done theJohn McCall
appropriate lookup and simply can't resolve the referrent yet, and "dependent scope" expressions, where we can't do the lookup yet because the entity we need to look into is a dependent type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89402 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-19Cope with an amusingly little anomaly with dependent types andDouglas Gregor
incomplete array initialization, where we have the following in a template: int a[] = { 1, 2, something-value-dependent }; // ... sizeof(a); The type of "a" appears to be a non-dependent IncompleteArrayType, but treating it as such makes the sizeof(a) fail at template definition time. We now correctly handle this by morphing the IncompleteArrayType into a DependentSizedArrayType with a NULL expression, indicating that its size has no corresponding expression (and, therefore, the type is distinct from others). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89366 91177308-0d34-0410-b5e6-96231b3b80d8
