// Test the following scenario:
// 1. Swift superclass with provably unused vtable methods eliminated by the optimizer.
// 2. Swift subclass dynamically set up at runtime.
// 3. Runtime copies the vtable when setting up the class.
// 4. Runtime encounters NULL entry for unused vtable method.
// 5. By random chance, the ptrauth signature for the NULL is 0.
// 6. The runtime checks for a pure, unsigned NULL and copies it verbatim.
// 7. Dynamically created subclass of Swift subclass.
// 8. Class copy fixup handler encounters the unsigned NULL and fails ptrauth.
// We should instead accept the unsigned NULL without faulting.

open class Sup<T>: NSObject {

  public func publicfunc() {}

  // Lots of unused internal functions makes this bug hit faster.
