                        IRET/IRETD - Interrupt Return

       Usage:  IRET
               IRETD  (386+ only)
       Modifies flags: AF CF DF IF PF SF TF ZF

       Returns control to point of interruption by popping IP, CS
       and then the Flags from the stack and continues execution at
       this location.  CPU exception interrupts will return to the
       instruction that cause the exception because the CS:IP placed
       on the stack during the interrupt is the address of the offending
       instruction.
