I think all you want here is:
  await_expr = convert_from_reference (await_expr);

Thanks, I'll update it.

Hi nathan,
Here is the update.

   /* This will produce the value (if one is provided) from the co_await
      expression.  */
   tree resume_call = TREE_VEC_ELT (awaiter_calls, 2); /* await_resume().  */
+  if (TREE_CODE (resume_call) == INDIRECT_REF)
+    /* Sink to await_resume call_expr.  */
+    resume_call = TREE_OPERAND (resume_call, 0);

sorry, I should have realized you still needed this bit.  This too is 
stripping a reference access, right?  I.e. TYPE_REF_P (TREE_TYPE 
(resume_call)) is true. You should that as the condition too.

the other part of the patch is fine
