    • calculateSpecificCallArity

      public int calculateSpecificCallArity()
      Returns a value useful for number of arguments we need for arity when generating call methods used by invokers and the JIT. Note: MAX_REQUIRED_UNBOXED_ARITY looks like some tweakable setting but it is merely for documentation. All our non-generated internal code is also locked to the same specific arities so we cannot just change this value and be happy.
      Returns:
      arity value of specific required arity which can be used as an unboxed call or -1 for all other cases.
