Simon Cruanes	d9b9f79b75	fix(smtlib/model): fix construction of models ... assign whole classes at once; make sure `compute_fixpoint` does not stop too early	2022-10-18 22:47:50 -04:00
Simon Cruanes	09d569ee68	fix test: restore printing for basic smt solver model	2022-10-15 23:17:49 -04:00
Simon Cruanes	4546b7cff2	feat(smt): produce better model, with eval function	2022-10-15 23:11:27 -04:00
Simon Cruanes	08541613af	refactor: model building in smtlib, for smtlib ... - sidekick.model removed, now just smtlib.Model (specific to it) - use function entries for models, not just term->term - re-building models in smtlib driver - asolver.solve, in Check_res.t, does not return a concrete model, but a bundle of functions to query the solver - store constants in smtlib typechecker AST (so we can directly map them to values in model construction)	2022-10-15 22:42:10 -04:00
Simon Cruanes	fb8614f304	feat: decode proofs from traces; print them in show_trace	2022-10-13 00:03:08 -04:00

Simon Cruanes	a47bbf45e8	refactor: use abstract-solver in smtlib driver; CDCL(T) implements asolver ... this way we can add new SMT techniques without changing (much) the driver.	2022-10-10 15:44:13 -04:00
Simon Cruanes	656d93d5fb	smt tracer is now a clause tracer	2022-10-02 23:23:34 -04:00
Simon Cruanes	96dddb5383	feat: show_trace, and trace_reader, can now display a QF_UF trace ... the trace can contain assertions.	2022-09-30 23:05:00 -04:00

Simon Cruanes	f7daf7e45e	wip: add theory combination to Preprocess, based on claim hooks ... theories must register hooks that specify what terms they claim for their own, so that preprocess (which look at all terms and has the global picture) can find where foreign terms are and give these to th combination.	2022-09-03 14:45:09 -04:00
