Question

Problem 5. The given assembly code is not correct for a procedure. Write the corrected version of the following assembly code. Your corrected version should preserve the functions main, func1, and func2 and also ensure that their main operations do not change. Please pay special attention to the line comments below. main addi $ao, $0, 20 addi $a1, $0,45 addi $s3,$ad, 6 #do not change this line al func1 add $s1, $v0, $s3 #$s3 needs to be $a0+6 as in line3 funcl: addi $s3, $ad, 50 #do not change this line add $a2, $s3, $a1 #do not change this line jal func2 addi vo, $v1, $ao jr Sra addi $v1,$a2,100 r Sra

Explanation / Answer

Please find the code below:::::

main:

addi $a0,$0, 20 #load 20 in a0

addi $a1, $0,45 #load 45 in a1

addi $s3,$a0, 6 #do not change this line

jal func1 #call func1

add $s1, $v0, $s3 #$s3 needs to be $a0+6 as in line3

func1:

move $t7,$ra #save return address to t7

move $t6,$s3 #save value of s3 to t6

addi $s3, $a0, 50 #do not change this line

add $a2, $s3, $a1 #do not change this line

jal func2

add $v0, $v1, $a0

move $ra,$t7

move $s3,$t6 #save value back to s3 so that it will be a0+6

jr $ra

#need to terminate execution now

li $v0,11

syscall

func2:

addi $v1,$a2,100

jr $ra
