Fix some warnings about unused stuff. (#6290) 2022-08-21 12:39:30 -07:00
Nikolaj Bjorner 48b13291d1 add bv-size reduce #6137 
- add option smt.bv.reduce_size.
  - it allows to apply incremental pre-processing of bit-vectors by identifying ranges that are known to be constant.
    This rewrite is beneficial, for instance, when bit-vectors are constrained to have many high-level bits set to 0.

Nikolaj Bjorner e0aa32e6c5 fix #6270 
MBQI asserts auxiliary function definitions to handle models of arrays. This is unsound if the definition contains a model value.

Nikolaj Bjorner 5c2c0ae900 force-push on new_eq, new_diseq in user propagator, other fixes to Python bindings for user propagator 
This update allows the python bindings for user-propagator to handle functions that are declared to be registered with the user propagator plugin. It fixes a bug in UserPropagateBase.add to allow registering terms dynamically during search.
It also fixes a bug in theory_user_propagate as scopes were not fully pushed when the solver gets the callbacks for new equalities and new disequalities.
It also adds equality and disequality interfaces to the sat/smt solver version (which isn't being exercised in earnest yet)

Nikolaj Bjorner b68af0c1e5 working on reconciling perf for arithmetic solvers 
this update integrates inferences to smt.arith.solver=6 related to grobner basis computation and handling of div/mod axioms to reconcile performance with smt.arith.solver=2.

The default of smt.arth.nl.grobner_subs_fixed is changed to 1 to make comparison with solver=2 more direct.

The selection of cluster equalities for solver=6 was reconciled with how it is done for solver=2.

Nikolaj Bjorner d7472f0726 fix #6124 
expression pointers were changed within a function, but not pinned. So the pointers got stale. To enforce their life-time within the function body (for use in logging) pin the expressions.
