- 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.
-
- 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.
