I'm new to this myself, but:

1. This sounds like a question better-suited for cfe-dev, not llvmdev.

2. NamedDecl::getNameAsString() is deprecated; use getName() instead.

3. NamedDecl also as getDeclName(), which is documented to return “the actual, stored name of the declaration, which may be a special name.”
