Predicate abstraction checks for simple example on the slides in SMT2 syntax: pred0.smt, pred1.smt, pred2.smt, pred3.smt, pred4.smt, pred5.smt. All should be 'sat', except for the last one pred5.smt, where we assume i != INT_MAX. The check pred2.smt actually shows, that we would need "b = *;" instead of "if (b) b = *;" if we consider bit-precise reasoning (so 32 bit 2-complement int and not integers).

C32SAT is a satisfiability checker for boolean C expressions. It can check whether they can be satisfied, are tautological, or can potentially be undefined according to the C99 standard.
