Module Name:

    bv_size_reduction.h

Abstract:

    Reduce the number of bits used to encode constants, by using signed bounds.
    Example: suppose x is a bit-vector of size 8, and we have
    signed bounds for x such that:
        -2 <= x <= 2
    Then, x can be replaced by  ((sign-extend 5) k)
    where k is a fresh bit-vector constant of size 3.
