Question

Translate the following C code into MIPS code.

int test (int n)

{

if (n < 2 ) return (10);

else

{

k = 20 + test (n-1);

k=k + n;

return (k);

}

}

Assume variable k is assigned to register $s1. Note: your code should be complete.

please dont show me the software output,

Answer 1

MIPS Code:

    .file       1
        .previous
        .text
        .align  2
        .globl  test
        .ent    test
        .type   test, @function
test:
        .frame  $sp,0,$31
        move    $2,$0
$L3:
        slt     $3,$4,2
        bne     $3,$0,$L2
        addiu   $4,$4,-1

        addiu   $3,$4,21
        b       $L3
        addu    $2,$2,$3

$L2:
        j       $31
        addiu   $2,$2,10

        .end    test
        .size   test, .-test
