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.

Flow
|
|
|
|
There are 2 label types: backward and forward. For each type,
|
|
there are two actions: set and write. Setting a label is
|
|
declaring where it is. It has to be performed at the label's
|
|
destination. Writing a label is writing its offset difference
|
|
to the binary result. It has to be done right after a relative
|
|
jump operation. Yes, labels are only for relative jumps.
