77 * Grab the register values as they are now.
78 * This won't do a particularily good job because we really
79 * want our caller's caller's registers, and our caller has
80 * already executed its prologue.
81 * ToDo: We could reach back into the caller's save area to do
82 * a better job of representing the caller's state (note that
83 * that will be different for 32-bit and 64-bit, because of the
84 * different ABIs, though).
