In this case the non-jump label -function is 80 bytes long. Thus, we have have saved 20% of the instruction +function is 80 bytes long. Thus, we have saved 20% of the instruction footprint. We can in fact improve this even further, since the 5-byte no-op really can be a 2-byte no-op since we can reach the branch with a 2-byte jmp. However, we have not yet implemented optimal no-op sizes (they are currently
