2009-05-27Simplify, and improve the performance of, template instantiation forDouglas Gregor
declaration references. The key realization is that dependent Decls, which actually require instantiation, can only refer to the current instantiation or members thereof. And, since the current context during instantiation contains all of those members of the current instantiation, we can simply find the real instantiate that matches up with the "current instantiation" template. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72486 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Add some more tests for instantiation of declaration references. Also,Douglas Gregor
improve some error recovery with explicit template instantiation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72484 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Enumeration declarations that were instantiated from an enumerationDouglas Gregor
within a template now have a link back to the enumeration from which they were instantiated. This means that we can now find the instantiation of an anonymous enumeration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72482 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-27Improve name lookup for and template instantiation of declarationDouglas Gregor
references. There are several smallish fixes here: - Make sure we look through template parameter scope when determining whether we're parsing a nested class (or nested class *template*). This makes sure that we delay parsing the bodies of inline member functions until after we're out of the outermost class (template) scope. - Since the bodies of member functions are always parsed "out-of-line", even when they were declared in-line, teach unqualified name lookup to look into the (semantic) parents. - Use the new InstantiateDeclRef to handle the instantiation of a reference to a declaration (in DeclRefExpr), which drastically simplifies template instantiation for DeclRefExprs. - When we're instantiating a ParmVarDecl, it must be in the current instantiation scope, so only look there. Also, remove the #if 0's and FIXME's from the dynarray example, which now compiles and executes thanks to Anders and Eli. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72481 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-27Initial stab at a generalized operation for determining theDouglas Gregor
