loads the updated stack pointer into the address register. Finally, adds the
displacement value to the stack pointer. For word-size operation, the displacement is
the sign-extended word following the operation word. For long size operation, the
displacement is the long word following the operation word. The address register
occupies one long word on the stack. The user should specify a negative displacement
in order to allocate stack area.
