f = (g + h) + (j + 13)

A[12] = h + A[8]

if (f != 0) {

}

if (j==h) f = g+h;

Solution

a)

add t0, g, h

add f, g, h

add t1, i, j

b)lw $t0, 32($s3)

add $t0, $s2, $t0

sw $t0, 48($s3)

c)

Let $s3->f

$s2->j

bne $s3,0,Else

Else:

add $s3, $s3, $s2

sub $s2,$2,1

Exit

d)

if (j !=h ) f = f + 1;

Let $s1=j,$s2=h,$s3=f,$s4=g

bne $s1,$s2,Else

add $s3,$s3,1

Else:add $s3,$s4,$s2

Exit

=====================================================

Let
$s1=j,$s2=h,$s3=f,$s4=g,$s5=address of A,
