Trouble with y86 bubble sort program - c

Question

So I am trying to convert a bubble sort program from assembly to Y86. I started with this C code and then converted it to assembly:
#include <stdio.h>
void bubble(int *, int);
int main(){
int count = 5;
int data[5]= {3, 2, 6, 1, 9,};
bubble(data, count);
return 0;
}
void bubble(int *data, int count){
int i, last;
for(last = count-1; last > 0; last--){
for (i=0; i < last; i++)
if (data[i+1] < data[i]){
/* Swap adjacent elements */
int t = data[i+1];
data[i+1] = data[i];
data[i] = t;
}
}
}
and this is my Y86 code:
init: irmovl Stack, %esp # Set up stack pointer
irmovl Stack, %ebp # Set up base pointer
call main # call main program
halt # Terminate program
main:
pushl %ebp

It seems as though the sign flag is never being raised, and I am not quite sure why this is. When I run the simulator, the elements of the array are never sorted, they just remain in the same position. Any tips on how to fix this would be much appreciated!
