[PATCH] D67028: Use musttail for variadic method thunks when possible

[Eli Friedman via Phabricator via cfe-commits]

efriedma added a comment.

Oops, meant to actually include the testcase in my last comment:

struct V1 { };
struct V2 : virtual V1 { };
struct A {

  virtual V1 *f(int,...);

};
struct B : A {

  virtual void b();
  virtual V2 *f(int,...);

};
B b;
