            Bug ID: 18776
           Summary: AST printer doesn't handle conversion operators
                    correctly
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org

$ cat t.cc
struct A {
  operator void*();
  A operator &(A);
};

void bar(void *);

void foo() {
  A a, b;
  bar(a & b);
}

$ clang -cc1 -ast-print t.cc
struct A {
    void *operator void *();
    A operator&(A);
};
void bar(void *);
void foo() {
    A a, b;
    bar(a & b.operator void *());
}

===

1. Printing a return type on a conversion operator is invalid.
2. If we really want to print the conversion operator call it should emit "(a &
b).operator void *()" to avoid changing behavior.
