             Bug #: 14129
           Summary: friend function is not marked with 'friend' in debug
           Product: clang
           Version: trunk
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: olga.a.chupina at gmail.com

Created attachment 9385
  --> http://llvm.org/bugs/attachment.cgi?id=9385
bitcode file

Consider following test:

$ cat test.cpp 
class X {
    int i;
    void m(int);         
    friend void f(X&);  

void X::m(int j) { i = j; }

void f(X& x) { x.i++; }

int main () 
    X x;
    return 0;

In debug info produced by the clang compiler (trunc and 3.1) the function f()
is a simple stand-alone function, class X has no member DW_AT_friend.

The bitcode file is attached.
