            Bug ID: 32645
           Summary: fixit hint for missing
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: nlewycky at google.com
                CC: dgregor at apple.com, llvm-bugs at lists.llvm.org

We do typo correction for . vs -> but we should also do "turn 'foo' into
'(*foo)'.

Testcase:

struct X { void foo(); };
void f() {
  X x1;
  X *x2 = &x1;
  X **x3 = &x2;
  x3->foo();
  *x3->foo();
}

$ clang++ b13503858.cc 
b13503858.cc:6:5: error: member reference base type 'X *' is not a structure or
      union
  x3->foo();
  ~~^ ~~~
b13503858.cc:7:6: error: member reference base type 'X *' is not a structure or
      union
  *x3->foo();
   ~~^ ~~~
2 errors generated.

Both of those should read "(*x3)->foo();", in both cases we're missing
parentheses and in the first case we're missing the * to dereference too.
