The only way to make this happens seems to somehow get the stuff into  
the actions, as Bison uses an algorithm, a form of LALR(1), to  
translate the input grammar to instructions for a so called push-down  
automaton. So the problem is similar to generate the language code  
from the binary. But if you can automate another semantic value  
component for the parse tree, plus actions for it, it might be an  
interesting addition to the Bison project.
