Translating Java to MIPS

For the Java statements on the left, provide the corresponding MIPS assembly code in the corresponding space on the right. Assume f, g, and j are assigned to registers $s0, $s1, and $s2 respectively, and h is assigned to register $v0. Also assume that the starting address of the array A (which is an array of 15 words) is in register $ra

C statements

MIPS Assembly code

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

A[12] = h + A[8]

if (f != 0) {

f = f + j;

j = j - 1;

}

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

f = f + A[2];

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

f = g + h;

THANKS IN ADVANCE!!

Explanation / Answer

Answer:

Assembly Language Code:

1)mov edx, DWORD PTR [rbp-4]
mov eax, DWORD PTR [rbp-8]
add edx, eax
mov eax, DWORD PTR [rbp-12]
add eax, 13
add eax, edx
mov DWORD PTR [rbp-16], eax

2)

mov edx, DWORD PTR [rbp-64]
mov eax, DWORD PTR [rbp-4]
add eax, edx
mov DWORD PTR [rbp-48], eax

3)

cmp DWORD PTR [rbp-4], 0
je .L2
mov eax, DWORD PTR [rbp-8]
add DWORD PTR [rbp-4], eax
sub DWORD PTR [rbp-8], 1

4)

mov eax, DWORD PTR [rbp-8]
cmp eax, DWORD PTR [rbp-12]
jne .L2
mov edx, DWORD PTR [rbp-16]
mov eax, DWORD PTR [rbp-12]
add eax, edx
mov DWORD PTR [rbp-4], eax
jmp .L3
.L2:
mov eax, DWORD PTR [rbp-16]
sub eax, DWORD PTR [rbp-12]
mov DWORD PTR [rbp-4], eax
.L3:
mov eax, DWORD PTR [rbp-136]
add DWORD PTR [rbp-4], eax

5)

mov eax, DWORD PTR [rbp-4]
cmp eax, DWORD PTR [rbp-8]
je .L2
add DWORD PTR [rbp-12], 1
.L2:
mov edx, DWORD PTR [rbp-16]
mov eax, DWORD PTR [rbp-8]
add eax, edx
mov DWORD PTR [rbp-12], eax
