The UNROLL pragma allows the loop to be fully or partially unrolled. Fully unrolling the loop creates a copy of the loop body in the RTL for each loop iteration, so the entire loop can be run concurrently. Partially unrolling a loop lets you specify a factor N, to create N copies of the loop body and reduce the loop iterations accordingly. To unroll a loop completely, the loop bounds must be known at compile time. This is not required for partial unrolling.
