I have some code that needs to be translated into Assembly. I am new to Assembly and I get confused and I think its pretty hard to write. I've gone through some tutorials but I am still getting problems when I compile the code. I need some help - Here is the original code and my code in Assembly. I am sure how to fix the issues: I gave some explanation of what I am trying to do in the Assembly code - I need to know if I am way off
Original Code:
int A[4] = {0, 1, 2, 3};
int x;
for ( int i = 0; i < 4; i++ )
{
if ( A[i] < 1 )
x = 1;
else
{
switch ( A[i] )
{
case 0:
x = 2;
case 1:
x = 3;
case 2:
x = 5;
case 3:
x = 7;
}
}
printf(“%d ”, x);
}
My Assembly Code
.data
jumpTab: .word lab0, lab1, lab2, lab3 #Jumptable
nums: .word 0,1,2,3 #array declaration of integers
numberx: .ascii "X equals: "
.text
main:
addi $t0, $0, 0 #Declare I
addi $t1, $0, 0 #Declare X
ori $t2, $t0, 4 # Constant Value 4
ori $t4, $t0, 1 # Constant Value 1
la $t3, nums #initialize Array Nums
forloop: bgt $t0, $t2 end #branch if i > four to end:
add $t0, $t0, $t0 Loop: #add i++ and go to loop:
loop: bgt $t3, $t4 Else #if Array Index (i) is more than 1 constant 1 branch
add $t1, $t1, 1
Else:
la $t5, JumpTable
sll $t5, $t6, 2 #offset
jr $t7
lab0:
la $t1, 2 #load address set x=2
j Print
lab1:
la $t1, 3 #load address set x=3
j Print
lab2:
la $t1, 5 #load address set x=5
j Print
lab3:
la $t1, 7 #load address set x=7
j Print
print: #print out X =
li $v0, 4
syscall
end:
