[cfe-dev] A question related to bug 5866.

[Enea Zaffanella]

Hello.

I was struggling against friend declarations of template function 
specializations, i.e., something strongly related to the following 
(resolved) bug:

   http://llvm.org/bugs/show_bug.cgi?id=5866

The problem we have is the following: when visiting a friend declaration 
such as the one used in the bug report above

     friend streamsize
     __copy_streambufs_eof<>(__streambuf_type*,
                             __streambuf_type*, bool&);

we call method getFriendDecl() and obtain a FunctionDecl*,
but when querying this pointer using method
     bool FunctionDecl::isFunctionTemplateSpecialization()
the answer turns out to be negative.

Is this a bug, or are we just calling the method above out of its 
specification? Are there other ways to check if a friend declaration is 
referring to a template function specialization?

Regards,
Enea.
