14 * Grab the register values as they are now.
15 * This won't do a particularly good job because we really
16 * want our caller's caller's registers, and our caller has

18 * ToDo: We could reach back into the caller's save area to do
19 * a better job of representing the caller's state (note that
20 * that will be different for 32-bit and 64-bit, because of the
21 * different ABIs, though).
