           Summary: anonymous namespace prevents codegen outside namespace
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: skabet at gmail.com
                CC: llvmbugs at cs.uiuc.edu, dgregor at apple.com

$ clang++ --version
clang version 2.9 (trunk 118011)
Target: x86_64-unknown-linux-gnu
Thread model: posix

$ clang++ -c bug.cpp -o out.o && nm out.o
(empty output)

$ cat bug.cpp
namespace { // removing namespace makes it work
  class Inner {

template<class D>
class _Outer{

  _Outer() {}

typedef _Outer<Inner> Outer;

class Foo {
  Outer bar() const;

Outer Foo::bar() const { // not emited. "nm out.o" is empty
  return Outer(); 


As seen, Foo::bar is not emited. Removing the anonymous namespace makes it
work. Changing the return type (Outer) to something not related the the
anonymous namespace also makes it work.
