For the MIPS assembly instructions below, what is the corresponding C statement? Assume that the variables f, g, h, i, and j are

assigned to registers $s0, $s1, $s2, $s3, and $s4, respectively. Assume that the base address of the arrays A and B are in registers $s6 and $s7, respectively. Assume that the elements of the arrays A and B are 4-byte words:

Answer:

lw $t0, 16($s7) // $t0 = B[4]

lw $t1, 12($s7) // $t1 = B[3]

sub $t0, $t0, $t1 // $t0 = B[4] – B[3]

sll $t0, $t0, 2 // $t0 = $t0 * 4

add $t0, $t0, $s6 // $t0 = &A[B[4] – B[3]]

lw $t1, 0($t0) // $t1 = A[B[4] – B[3]]

add $s0, $s1, $t1 // f = g + A[B[4] – B[3]
