Hi Fernando

i'm aware of the paper. For some time, i thought that it would make it to the
Trimaran newer releases (this was around 2002-2003). I don't know if this
approach to bitwidth analysis has made to Trimaran 4.0, but it looks like that
it is the basis of commercial technology (i can name the company that uses it,
if it is necessary).

You can ask Rodric Rabbah from MIT, i'm sure he keeps pace with something close
to Stephenson's implementation.

Kind regards
Nikolaos Kavvadias
