Please format the comment to make it more obvious what the input/
outputs are. Here are some good examples to follow:
// RESULT, OUTCHAIN = EXCEPTIONADDR(INCHAIN) - This node
// address of the exception block on entry to an landing pad block.
// RESULT, OUTCHAIN = EHSELECTION(INCHAIN, EXCEPTION) - This node
// the selection index of the exception thrown.
