The sbv package

[Tags: bsd3, library, program]

Express properties about bit-precise Haskell programs and automatically prove them using SMT solvers. Automatically generate C programs from Haskell functions. The SBV library adds support for symbolic bit vectors, allowing formal models of bit-precise programs to be created.

   $ ghci -XScopedTypeVariables
   Prelude> :m Data.SBV
   Prelude Data.SBV> prove $ \(x::SWord8) -> x `shiftL` 2 .== 4*x
   Q.E.D.
   Prelude Data.SBV> prove $ forAll ["x"] $ \(x::SWord8) -> x `shiftL` 2 .== x
   Falsifiable. Counter-example:
     x = 128 :: SWord8

The library introduces the following types and concepts:

Functions built out of these types can be:

Predicates can have both existential and universal variables. Use of alternating quantifiers provides considerable expressive power. Furthermore, existential variables allow synthesis via model generation.

The SBV library can also compile Haskell functions that manipulate symbolic values directly to C, rendering them as straight-line C programs.

In addition to the library, the installation will create the executable SBVUnitTests. You should run it once the installation is complete, to make sure the unit tests are run and all is well.
