I have a code

#pragma omp for
for (i = 0; i < length; i++)
{
   A[i] = A[i] * B[i];
}

After I compile it to LLVM IR, I need to get the instructions only that is not inside the "for" part (incremental operation), because I only want to get the instructions that is related to A[i] = A[i] * B[i]. How do I do that?
