Module Name:

    bv1_blaster_tactic.h

Abstract:

    Rewriter for "blasting" bit-vectors of size n into bit-vectors of size 1.
    This rewriter only supports concat and extract operators.
    This transformation is useful for handling benchmarks that contain
    many BV equalities. 

    Remark: other operators can be mapped into concat/extract by using
    the simplifiers.
