Write your own exception handler as per the discussion in 2.4 Task 3:

2.4 Task 3 Write your own exception handler that prints the address of the instruction that caused the exception, the exception code and an accompanying message. Example outputs include: # w8overflow.asm Exception caused by instruction at Address: 0x0040000c Exception Code = 12 Ignore and continue program ... -- program is finished running -- A few important points to keep in mind: The exception handler must start at the fixed address 0x80000180. This address is in the kernel text segment. An exception handler can be written in the same file as the regular program, or in a separate file. Write your exception handler solution in a separate .asm file. Use the supplied w8zerodivide.asm file to invoke your exception handler. Submit this run and result for your lab deliverable (i.e. include snapshots of the MARS Message window and the MARS Run I/O window). (Be sure to upload your exception handler solution into MARS for your test run demonstration).

1. Use the provided w8zerodivide.asm file for your test run.

# Lab 7 CS10 w8zerodivide.asm

# Example program which causes an exception

# Use your lab8 exception handler

#

.text

.globl main

main: li $t1, 300

li $t0, 0

div $a0, $t1, $t0# Do $a0 = $t1 / $t0

li $v0, 1 # Print result as an integer

syscall

li $v0, 10 # and exit

syscall

2. Your handler should print the address of the instruction that causes the exception, the exception code and an accompanying message.
