Backward jumps are trivial; the distance is known because the code has been generated. But how do you assess the jump distance for forward jumps without a second pass? This;

   jmp B
   ...code...
   jmp A
   ...code...
B: ...code...
A: ...code...

requires that the jump to B is dependant on the length of the jump to A opcode. Can you describe how you optimise this in one pass?
