Nikolaj Bjorner	cfc8e19baf	add more simplifiers, fix model reconstruction order for elim_unconstrained ... - enable sat.smt in smt_tactic that is invoked by default on first goals add flatten-clauses add push-ite have tptp5 front-end pretty print SMT2 formulas a little nicer.	2022-12-01 02:35:43 +09:00
Nikolaj Bjorner	b084821a0c	wip - dependent expr simpliifer ... - simplify iterator over current indices - 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)	2022-11-30 08:35:29 +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.	2022-11-29 16:36:02 +07:00
Nikolaj Bjorner	500626e814	add sat-smt-preprocess module ... self-contained pre-processing initialization	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.	2022-11-28 11:45:56 +07:00
Nikolaj Bjorner	4e9f21c2a1	add rewriter and seq simplifiers	2022-11-25 15:16:14 +07:00
