CVC4 is mostly SMT-LIB-conforming with --lang smt. With the --smtlib command line option, though, you get additional strictness and standards conformance.
There are areas where we don't support full functionality, or where we are not compliant:
- We do not yet support the to_real or to_int functions, nor the is_int predicate, from the Reals_Ints theory.
- We do not yet support unsat core extraction (the get-unsat-core command)
- We do not yet adequately support nonlinear-arithmetic (the QF_NIA, QF_NRA, QF_UFNRA, UFNRA, and AUFNIRA logics)
Also:
- We do not yet support Boolean terms, e.g., function symbols that take Boolean arguments or arrays of Boolean.
This limitation should be fixed by the 1.0 release.
- We do not yet support abstract values. An array can itself be printed as a term, and even a function can be printed (as a lambda).
We plan to support abstract values when running in --smtlib compliance mode, by the 1.0 release.
