b53da182b6 fix gen_assign_unroll_reg so that it does not assert a contradiction 2016-06-30 04:39:09 -04:00
Murphy Berzish
a2d6149df5 add general-case regex unroll model generation 
WIP as there is currently a SAT-as-UNSAT bug I'm trying to fix

This also changes the semantics of lower_bound and upper_bound,
no longer wrapping the expr that is passed in with mk_strlen().
This actually makes these methods useful for checking bounds
of things other than strings.
