            Bug ID: 30943
           Summary: __PRETTY_FUNCTION__ does not use the new c++11
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

When __PRETTY_FUNCTION__ creates the function signature, it should use the new
c++11 namespace.

Minimal test case:

#include <stdio.h>
#include <string>

std::string foo()
  printf("%s\n", __PRETTY_FUNCTION__);
  return "";

int main(int argc, char **argv)

When compiled and run with:
- g++ and -D_GLIBCXX_USE_CXX11_ABI=0:
std::string foo()

- g++ and -D_GLIBCXX_USE_CXX11_ABI=1 (default for g++):
std::__cxx11::string foo()

- clang++ (4.0.0-svn286079-1~exp1):
std::string foo()

I think clang should output "std::__cxx11::string foo()", at least for
compatibility with g++.
