2010-03-29When collecting virtual bases it's very important to use the canonical type ↵Anders Carlsson
of the base class. Otherwise, we might add the same virtual base class twice if the virtual base is an instantiated template. Fixes PR6251. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99829 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-11Split C++ friend declarations into their own header/implementation file.John McCall
I'm expecting this portion of the AST to grow and change, and I'd like to be able to do that with minimal recompilation. If this proves unnecessary when access control is fully-implemented, I'll fold the classes back into DeclCXX.h. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98249 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-10Create a new InjectedClassNameType to represent bare-word references to the John McCall
injected class name of a class template or class template partial specialization. This is a non-canonical type; the canonical type is still a template specialization type. This becomes the TypeForDecl of the pattern declaration, which cleans up some amount of code (and complicates some other parts, but whatever). Fixes PR6326 and probably a few others, primarily by re-establishing a few invariants about TypeLoc sizes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98134 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-26Implement semantic analysis for C++ [expr.new]p18-20, which describeDouglas Gregor
how we find the operator delete that matches withe operator new we found in a C++ new-expression. This will also need CodeGen support. On a happy note, we're now a "nans" away from building tramp3d-v4. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97209 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Perform two more constructor/destructor code-size optimizations:John McCall
1) emit base destructors as aliases to their unique base class destructors under some careful conditions. This is enabled for the same targets that can support complete-to-base aliases, i.e. not darwin. 2) Emit non-variadic complete constructors for classes with no virtual bases as calls to the base constructor. This is enabled on all targets and in theory can trigger in situations that the alias optimization can't (mostly involving virtual bases, mostly not yet supported). These are bundled together because I didn't think it worthwhile to split them, not because they really need to be. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96842 91177308-0d34-0410-b5e6-96231b3b80d8

Also cuts down on memory usage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95330 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-31Rework base and member initialization in constructors, with severalDouglas Gregor
(necessarily simultaneous) changes: - CXXBaseOrMemberInitializer now contains only a single initializer rather than a set of initialiation arguments + a constructor. The single initializer covers all aspects of initialization, including constructor calls as necessary but also cleanup of temporaries created by the initializer (which we never handled before!). - Rework + simplify code generation for CXXBaseOrMemberInitializers, since we can now just emit the initializer as an initializer. - Switched base and member initialization over to the new initialization code (InitializationSequence), so that it - Improved diagnostics for the new initialization code when initializing bases and members, to match the diagnostics produced by the previous (special-purpose) code. - Simplify the representation of type-checked constructor initializers in templates; instead of keeping the fully-type-checked AST, which is rather hard to undo at template instantiation time, throw away the type-checked AST and store the raw expressions in the AST. This simplifies instantiation, but loses a little but of information in the AST. - When type-checking implicit base or member initializers within a dependent context, don't add the generated initializers into the AST, because they'll look like they were explicit. - Record in CXXConstructExpr when the constructor call is to initialize a base class, so that CodeGen does not have to infer it from context. This ensures that we call the right kind of constructor. There are also a few "opportunity" fixes here that were needed to not regress, for example: - Diagnose default-initialization of a const-qualified class that does not have a user-declared default constructor. We had this diagnostic specifically for bases and members, but missed it for variables. That's fixed now. - When defining the implicit constructors, destructor, and copy-assignment operator, set the CurContext to that constructor when we're defining the body. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94952 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-14When qualified lookup into the current instantiation fails (because itDouglas Gregor
finds nothing), and the current instantiation has dependent base classes, treat the qualified lookup as if it referred to an unknown specialization. Fixes PR6031. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93433 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-05Improve key-function computation for templates. In particular:Douglas Gregor
- All classes can have a key function; templates don't change that. non-template classes when computing the key function. - We always mark all of the virtual member functions of class template instantiations. - The vtable for an instantiation of a class template has weak linkage. We could probably use available_externally linkage for vtables of classes instantiated by explicit instantiation declarations (extern templates), but GCC doesn't do this and I'm not 100% that the ABI permits it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92753 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
2009-11-18Incremental progress on using declarations. Split UnresolvedUsingDecl intoJohn McCall
two classes, one for typenames and one for values; this seems to have some support from Doug if not necessarily from the extremely-vague-on-this-point standard. Track the location of the 'typename' keyword in a using-typename decl.

2009-11-16First part of changes to eliminate problems with cv-qualifiers andDouglas Gregor
sugared types. The basic problem is that our qualifier accessors (getQualifiers, getCVRQualifiers, isConstQualified, etc.) only look at the current QualType and not at any qualifiers that come from sugared types, meaning that we won't see these qualifiers through, e.g., typedefs: typedef const int CInt; typedef CInt Self; Self.isConstQualified() currently returns false! Various bugs (e.g., PR5383) have cropped up all over the front end due to such problems. I'm addressing this problem by splitting each qualifier accessor into two versions: - the "local" version only returns qualifiers on this particular QualType instance - the "normal" version that will eventually combine qualifiers from this QualType instance with the qualifiers on the canonical type to produce the full set of qualifiers. This commit adds the local versions and switches a few callers from the "normal" version (e.g., isConstQualified) over to the "local" version (e.g., isLocalConstQualified) when that is the right thing to do, e.g., because we're printing or serializing the qualifiers. Also, switch a bunch of Context.getCanonicalType(T1).getUnqualifiedType() == Context.getCanonicalType(T2).getQualifiedType() expressions over to Context.hasSameUnqualifiedType(T1, T2) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88969 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-14If we attempt to add a constructor template specialization that looksDouglas Gregor
like a copy constructor to the overload set, just ignore it. This ensures that we don't try to use such a constructor as a copy constructor *without* triggering diagnostics at the point of declaration. Note that we *do* diagnose such copy constructors when explicitly written by the user (e.g., as an explicit specialization). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88733 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-07Make sure isCopyAssignment is only true for actual copy assignment operators,Eli Friedman
