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.
