[LLVMdev] No SSE instructions

Hello.
I have compiled the simple program:

#include <stdio.h>
#include <stdlib.h>

int v1[10000];

int main()
{
        int i;

        for (i = 0; i < 10000; i++) {
                v1[i] = i;
        }

        for (i = 0; i < 10000; i++) {
                printf("%d ", v1[i]);
        }

        return 0;
}

Next, I disasseble the executable file and have not found any SSE
instructions.
I know that LLVM support SSE.
So my questions:
  1. It is occur only in my computer?
  2. If it is not only my bug, then there are not SSE optimizations in
LLVM?
  3. Have anyone, already worked on this problem?
