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.

Tactic Documentation:
## Tactic bv1-blast
### Short Description
Reduce bit-vector expressions into bit-vectors of size 1 (notes: only equality, extract and concat are supported).
### Long Description
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.
### Example
```z3
(declare-const x (_ BitVec 8))
(declare-const y (_ BitVec 4))
(declare-const z (_ BitVec 4))
(assert (= (concat y z) x))
(apply bv1-blast)
```
