C to MIPS Conversion

C variable	h	i	j	k	x	int a[] or &a[0]
MIPS register replacement	$s0	$s1	$s2	$s3	$s4	$a0

Translate to MIPS. DO NOT USE pseudo MIPS instructions (e.g., BGE). Answer MUST use true 32-bit MIPS instructions:

if(j < k )
  a[j] = 1;
else 
  j = a[j];

Answer #1

Note :- I have only used instead li I have used addi and instead of BGE I have used slt and beq. Please check and please change the rating in the previous one also please. Any issue please comment I can help you. And, if $zero gives compiler issues; then use $0 as it is depends on compiler

Given register file:
h = $s0
i = $s1
j = $s2
k = $s3
x = $s4
&a[0] = $a0

MIPS PROGRAM :-

IF_BLOCK:

#calculating address of a[j]
sll $t0, $s2, 2
add $t0, $t0, $a0

#if(j<k)
slt $t1, $s2, $s3 #checking for j<k;
beq $t1, $zero, ELSE_PART #if fails then else part

addi $t1, $zero, 1
sw $t1,0($t0) #a[j]=1

ELSE_PART:
lw $s2, 0($t0) #j=a[j]
