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. Make a new lookup result for unresolved values and deal with it in most places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89184 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-17Do not register ObjCInterfaceDecls implicitly created by @class in theTed Kremenek
current DeclContext. These "imaginary" declarations pose issues for clients searching DeclContext for actual declarations. Instead, register them for name lookup, and add the ObjCInterfaceDecl later to the DeclContext when we hit an actual @interface declaration. This also fixes a bug where the invariant that the Decls in a DeclContext are sorted in order of their appearance is no longer violated. What could happen is that an @class causes an ObjCInterfaceDecl to get added first to the DeclContext, then the ObjCClassDecl itself is added, and then later the SourceLocation of the ObjCInterfaceDecl is updated with the correct location (which is later in the file). This breaks an assumed invariant in ResolveLocation.cpp (and possibly other clients). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89160 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-17When querying type qualifiers on QualType via one of the "non-local"Douglas Gregor
interfaces (which are used throughout the front end), combine the qualifiers on the QualType instance with the qualifiers on the canonical type to produce the set of qualifiers that, semantically, apply to that type. This should design away a large category of "qualifier-hidden-behind-a-typedef" buts like we saw in PR5383. Performance-wise, this caused a regression of ~0.5% on Cocoa.h, but it's totally worth it. We may actually be able to get a little more performance back by using CanQualType more often. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89018 91177308-0d34-0410-b5e6-96231b3b80d8
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

2009-11-12When comparing template parameter lists, distinguish between three cases:Douglas Gregor
- Comparing template parameter lists to determine if we have a redeclaration - Comparing template parameter lists to determine if we have equivalent template template parameters - Comparing template parameter lists to determine whether a template template argument is valid for a given template template parameter. Previously, we did not distinguish between the last two cases, which got us into trouble when we were looking for exact type matches between the types of non-type template parameters that were dependent types. Now we do, so we properly delay checking of template template arguments until instantiation time. Also, fix an accidental fall-through in a case statement that was causing crashes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86992 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-11Template argument deduction for template template parameters. ThisDouglas Gregor
permits, among other things, ripping apart and reconstructing templates via partial specialization: template<typename T> struct DeepRemoveConst { typedef T type; }; template<typename T> struct DeepRemoveConst<const T> { typedef typename DeepRemoveConst<T>::type type; }; template<template<typename> class TT, typename T> struct DeepRemoveConst<TT<T> > { typedef TT<typename DeepRemoveConst<T>::type> type; }; Also, fix a longstanding thinko in the code handling partial ordering of class template partial specializations. We were performing the second deduction without clearing out the results of the first deduction. It's amazing we got through so much code with such a horrendous error :( git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86893 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Fix speculative parsing of dependent template names inDouglas Gregor
nested-name-specifiers so that they don't gobble the template name (or operator-function-id) unless there is also a template-argument-list. For example, given T::template apply we would previously consume both "template" and "apply" as part of parsing the nested-name-specifier, then error when we see that there is no "<" starting a template argument list. Now, we parse such constructs tentatively, and back off if the "<" is not present. This allows us to parse dependent template names as one would use them for, e.g., template template parameters: template<typename T, template<class> class X = T::template apply> struct MetaSomething; Also, test default arguments for template template parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86841 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-11Introduce a new representation for template templateDouglas Gregor
parameters. Rather than storing them as either declarations (for the non-dependent case) or expressions (for the dependent case), we now (always) store them as TemplateNames. The primary change here is to add a new kind of TemplateArgument, which stores a TemplateName. However, making that change ripples to every switch on a TemplateArgument's kind, also affecting TemplateArgumentLocInfo/TemplateArgumentLoc, default template arguments for template template parameters, type-checking of template template arguments, etc. This change is light on testing. It should fix several pre-existing problems with template template parameters, such as: - the inability to use dependent template names as template template arguments - template template parameter default arguments cannot be instantiation However, there are enough pieces missing that more implementation is required before we can adequately test template template parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86777 91177308-0d34-0410-b5e6-96231b3b80d8
