2009-10-08Improve checking for specializations of member classes of classDouglas Gregor
templates, and keep track of how those member classes were instantiated or specialized. Make sure that we don't try to instantiate an explicitly-specialized member class of a class template, when that explicit specialization was a declaration rather than a definition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83547 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-26Rework the Parse-Sema interaction for friends to better support friendDouglas Gregor
class templates. We now treat friend class templates much more like normal class templates, except that they still get special name lookup rules.

Something strange is going on here; this test randomly started failing after unrelated changes to TestRunner.py (even though it runs the same script). Argiris or Doug, can one of you investigate? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77063 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22Implement support for out-of-line definitions of the class members of classDouglas Gregor
templates, e.g., template<typename T> struct Outer { struct Inner; }; template<typename T> struct Outer<T>::Inner { // ... }; Implementing this feature required some extensions to ActOnTag, which now takes a set of template parameter lists, and is the precursor to removing the ActOnClassTemplate function from the parser Action interface. The reason for this approach is simple: the parser cannot tell the difference between a class template definition and the definition of a member of a class template; both have template parameter lists, and semantic analysis determines what that template parameter list means. There is still some cleanup to do with ActOnTag and ActOnClassTemplate. This commit provides the basic functionality we need, however. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76820 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-25Improved semantic analysis and AST respresentation for functionDouglas Gregor
templates. For example, this now type-checks (but does not instantiate the body of deref<int>): template<typename T> T& deref(T* t) { return *t; } void test(int *ip) { int &ir = deref(ip); } Specific changes/additions: * Template argument deduction from a call to a function template. * Instantiation of a function template specializations (just the declarations) from the template arguments deduced from a call. * FunctionTemplateDecls are stored directly in declaration contexts and found via name lookup (all forms), rather than finding the FunctionDecl and then realizing it is a template. This is responsible for most of the churn, since some of the core declaration matching and lookup code assumes that all functions are FunctionDecls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74213 91177308-0d34-0410-b5e6-96231b3b80d8
