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.
|
|
|
|
For backward labels, set happens before write. For forward
|
|
labels, write happen before set. The write operation writes a
|
|
dummy placeholder, and then the set operation writes the offset
|
|
at that placeholder's address.
