<p>
Branches and direct jumps are always written as offsets to the PC, or as
jumps to labels:
</p>

<pre>
label:
	MOVW $0, R1
	JMP label
</pre>

<p>
Each label is visible only within the function in which it is defined.
It is therefore permitted for multiple functions in a file to define
and use the same label names.
Direct jumps and call instructions can target text symbols,
