Labels are a convenient way of managing relative jump
|
|
calculations. Backward labels are easy. It is only a matter or
|
|
recording "HERE" and do subtractions. Forward labels record the
|
|
place where we should write the offset, and then when we get to
|
|
that point later on, the label records the offset there.
|
|
|
|
To avoid using dict memory in compilation targets, we
|
|
pre-declare label variables here, which means we have a limited
|
|
number of it. For now, 4 ought to be enough.
