- add more simplifiers used by asserted_formulas
- improve diagnostics printing
 2022-11-30 13:41:40 +07:00
Nikolaj Bjorner bec3acd146 consolidate freeze functionality into dependent_expr_state 
rename size() to qtail() and introduce shortcuts
ensure tactic goals are not updated if they are in inconsistent state (because indices could be invalidated)

Nikolaj Bjorner 73a652cf4b some fixes to backtracking restore points in new solver 2022-11-29 16:42:42 +07:00
Nikolaj Bjorner dd1ca8f6bd move qhead to attribute on the state instead of the simplifier, 
- add sat.smt option to enable the new incremental core (it is not ready for mainstream consumption as cloning and other features are not implemented and it hasn't been tested in any detail yet).
- move "name" into attribute on simplifier so it can be reused for diagnostics by the seq-simplifier.

Nikolaj Bjorner ac023935a3 introduce sat-smt-solver 
in an iteration of inc-sat-solver introduce sat-smt-solver to allow incremental pre-processing.
The aim is to allow incrementally handling formulas while at the same time retaining the main benefits of global in/pre-processing that change models. Previous incremental solving capabilities have been limited to use pre-processing that does not require model conversion.

 2022-11-28 12:13:00 +07:00
Nikolaj Bjorner 85f9c7eefa replace restore_size_trail by more generic restore_vector 
other updates:
- change signature of advance_qhead to simplify call sites
- have model reconstruction replay work on a tail of dependent_expr state, while adding formulas to the tail.

Nikolaj Bjorner a152f9cfd6 port bit-blaster to simplifiers 
inc_sat_solver uses bit-blaster, card2bv and max_bv_sharing.
By turning these into simplifiers it will be possible to remove
dependencies on tactics and goals in inc_sat_simplifier and instead use a modular and general incremental pre-processing infrastructure.
