2011-01-18Add support for explicit constructor calls in Microsoft mode.Francois Pichet
For example: class A{ public: A& operator=(const A& that) { if (this != &that) { this->A::~A(); this->A::A(that); // <=== explicit constructor call. } return *this; } }; More work will be needed to support an explicit call to a template constructor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123735 91177308-0d34-0410-b5e6-96231b3b80d8

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3206.htm This lands support for parsing virt-specifier-seq after member functions, including the contextual keywords 'final', and 'override'.

2011-01-16Tweak the partial ordering rules for function templates to prefer aDouglas Gregor
non-variadic function template over a variadic one. This matches GCC and the intent of the C++0x wording, in a way that I think is likely to be acceptable to the committee. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123581 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-15Introduce a new kind of TemplateName that captures a substitutedDouglas Gregor
template template parameter pack that cannot be fully expanded because its enclosing pack expansion could not be expanded. This form of TemplateName plays the same role as SubstTemplateTypeParmPackType and SubstNonTypeTemplateParmPackExpr do for template type parameter packs and non-type template parameter packs, respectively. We should now handle these multi-level pack expansion substitutions anywhere. The largest remaining gap in our variadic-templates support is that we cannot cope with non-type template parameter packs whose type is a pack expansion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123521 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-14When we're instantiating a direct variable initializer that has a packDouglas Gregor
expansion in it, we may end up instantiating to an empty expression-list. In this case, the variable is uninitialized; tweak the instantiation logic to handle this case. Fixes PR8977. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123449 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-14Keep track of the number of expansions to be produced from a type packDouglas Gregor
expansion, when it is known due to the substitution of an out parameter pack. This allows us to properly handle substitution into pack expansions that involve multiple parameter packs at different template parameter levels, even when this substitution happens one level at a time (as with partial specializations of member class templates and the signatures of member function templates). Note that the diagnostic we provide when there is an arity mismatch between an outer parameter pack and an inner parameter pack in this case isn't as clear as the normal diagnostic for an arity mismatch. However, this doesn't matter because these cases are very, very rare and (even then) only typically occur in a SFINAE context. The other kinds of pack expansions (expression, template, etc.) still need to support optional tracking of the number of expansions, and we need the moral equivalent of SubstTemplateTypeParmPackType for substituted argument packs of template template and non-type template parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123448 91177308-0d34-0410-b5e6-96231b3b80d8
