Modifying a TRAP Routine: For problem types (4), (5), and (6) in table 6.3, add code to the
TRAP routine to check the instruction and input data as indicated in table 6.7 and to write the
contents of qNaN to the destination register.
In this case the value of qNaN must always be H'7FF7FFFF_FFFFFFFF.
