Hi Marcelo,
as far as I remember, this is not possible in the released version of
LLBMC. The reason for this is that we use the SMT solvers' C APIs
directly.
In our current development version we added support for dumping to
SMTLIB and SMTLIB2 format. We hope to provide a new release of LLBMC
soon which will include this feature.
Bes regards,
Florian Merz
