use tmll?

[JaideepBajwa, 2017/04/11 22:45:01]

I tried changing to
  __ tmll(r5, Operand(static_cast<int>(SuspendFlags::kAsyncGeneratorAwait)));
  __ bne(&async_await);
But that is causing some failures, am I missing anything?

   __ CmpP(r5, Operand(static_cast<int>(SuspendFlags::kAsyncGeneratorAwait)));
   __ beq(&async_await);
