Question $1)$ Using MIPS$($MARS $4\mathrm{.}5)$ Assembly language. Please comment and screenshot the code. Change the PrintIntArray subprogram so that it prints the array from the last element to the first element. Please answer the two exercise questions at the end of Ch $9.$ Just in case I took a screenshot of the code and will copy and paste it$.$

Heres the code:

$.$text

$.$globl main

main:

la $a$0,$ array$\_$base

lw $a$1,$ array$\_$size

jal PrintIntArray

jal Exit

$.$data

array$\_$size: $.$word $5$

array$\_$base:

$.$word $12$

$.$word $7$

$.$word $3$

$.$word $5$

$.$word $11$

# Subprogram: PrintIntArray# Purpose: print an array of ints# inputs:

$a$0-$ the base address of the array

# $a$1-$ the size of the array

$.$text

PrintIntArray:

addi $sp$,$ $sp$,-16$ # Stack record

sw $ra$,0($$sp$)$

sw $s$0,4($$sp$)$

sw $s$1,8($$sp$)$

sw $s$2,12($$sp$)$

move $s$0,$ $a$0$ # save the base of the array to $s$0$

# initialization for counter loop # $s$1$ is the ending index of the

loop

# $s$2$ is the loop counter

move $s$1,$ $a$1$ move $s$2,$ $zero la $a$0$ open$\_$bracket #

print open bracket jal PrintString

loop: # check ending condition

sge $t$0,$ $s$2,$ $s$1$bnez $t$0,$ end$\_$loop

sll $t$0,$ $s$2,2$ # Multiply the loop counter by $4$ to get

# offset

$($each element is $4$ big$)$

add $t$0,$ $t$0,$ $s$0$ # address of next array element

lw $a$1,0($$t$0)$ # Next array element

la $a$0,$ comma

jal PrintInt # print the integer from array

addi $s$2,$ $s$2,1$ #increment $s$0$

b loop

end$\_$loop:

li $v$0,4$ # print close bracket la $a$0,$

close$\_$bracket

syscall

lw $ra$,0($$sp$)$

lw $s$0,4($$sp$)$

lw $s$1,8($$sp$)$

lw $s$2,12($$sp$)$ # restore stack and return

addi $sp$,$ $sp$,16$
