            Bug ID: 27009
           Summary: [ms] no matching member function for call when
                    argument has a __restrict qualifier
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org
          Reporter: andrey.kuleshov at intel.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

!- In this case clang cannot find matching function for a call, when an
argument that is passed to a function call is declared with a __restrict
qualifier.
This problem appears only with template classes. 
MSVC can compile such code without any errors. -!

========Environment=========
OS: Win
Language: c++
Version: trunk

========Reproducer==========
template< class T >
class C{
public:
  void foo();
  void foo(const T& src);
};

struct B{
  int a;
};

class A {
C<B *> m_t;
  void bar(){
     B *
       #ifndef OK // use "clang-cl -DOK test.cpp" to remove an error 
       __restrict
       #endif
     p;
     m_t.foo(p);
  }
};

==========Error============
>>>clang:
test.cpp(20,10) :  error: no matching member function for call to 'foo'
     m_t.foo(p);

>>>msvc:
<no diagnostics>
