Question

Help me translate this C code into MIPS

int set(int n, int a[], int v)

{

int i;

for (i=4; i < (n-1); i++){

a[i] = v;

}

return i;

}

Answer 1

Given, Convert the given c code to the MIPS assembly code

C Code:

int set(int n, int a[], int v)
{
int i;
for (i=4; i < (n-1); i++)
{
a[i] = v;
}
return i;
}

Please check the below MIPS code which gives the proper functionality of the given c code.

MIPS Code:

set:
addiu $sp,$sp,-24
sw $fp,20($sp)
move $fp,$sp
sw $4,24($fp)
sw $5,28($fp)
sw $6,32($fp)
li $2,4 # 0x4
sw $2,8($fp)
b $L2
nop

$L3:
lw $2,8($fp)
nop
sll $2,$2,2
lw $3,28($fp)
nop
addu $2,$3,$2
lw $3,32($fp)
nop
sw $3,0($2)
lw $2,8($fp)
nop
addiu $2,$2,1
sw $2,8($fp)
$L2:
lw $2,24($fp)
nop
addiu $3,$2,-1
lw $2,8($fp)
nop
slt $2,$2,$3
bne $2,$0,$L3
nop

lw $2,8($fp)
move $sp,$fp
lw $fp,20($sp)
addiu $sp,$sp,24
j $31
nop
