To enable, use --check-models. Turning on the option can be done in debug or optimized builds, regardless of whether normal assertions are on or not. This is to allow us to check the generated models in long-running queries, and might be useful to end users as a double-check too.
By default, --check-models is quiet (no output unless it detects a problem). That allows regression runs to pass unless there are problems:
make regress CVC4_REGRESSION_ARGS=--check-models
To see it work, use -v in addition to --check-models.
There may still be bugs in the feature itself, but already I've found some apparent model-generation bugs (and discussed with Andy) from this feature, so it seems useful in its current state.
--check-models turns on what SMT-LIBv2 calls "interactive mode" (which keeps the list of user assertions around), and also implies --produce-models. This version does NOT require incremental-mode, which one design did (the one mentioned in yesterday's meeting).
Also:
* TheoryUF::collectModelInfo() now generates UninterpretedConstants (rather than non-constants)
* The UF rewriter now reduces (APPLY_UF (LAMBDA...) args...), and treats uninterpreted constants correctly (e.g. uc_U_1 != uc_U_2)
* The SubstitutionMap now supports substitutions of operators for paramaterized kinds (e.g., function symbols)

A "command executer" layer between parsing commands and invoking them.
New implementation of portfolio driver splits only when check-sat or query
command is encountered, and then switches back to sequential till the next
one. As side effect, restores functionality of interactive mode and
push/pops.

Make SmtEngine::internalPop() delay popping. This fixes a bug in model generation.

collectModelInfo with fullModel argument, most theory-specific implementation out of the model class, model printer relegated to printer classes. Also updates to finite mode finding, modifications to datatypes making them compatible with theory combination, support for theory-specific handling of user attributes, refactoring of uf models

* Remove sat_module.cpp, which was no longer used (was previously refactored?)
|
|
* Fix "make distclean." This should fix the "local regressions fail"
that caused documentation, debian, and "distcheck" nightly build targets
to fail.
* "make clean" now removes some options stuff that previously required a
"make distclean."
* Cosmetic and portability adjustments.

Replace all cardinality comparison functions <=, ==, !=, >=, <, >, with a single compare() function that can return UNKNOWN in the case of unknown (or large-finite and thus not *precisely* known) cardinalities.

Andy saw when adding options & re-making, which was caused by sources not being properly recompiled when they should be

Here's a fun way to give yourself a week-long headache: try to figure out how
to write efficient code to normalize array constants.
It's mostly there now - just need to figure out how to use type enumerators and
update once the new cardinality stuff is in place.

Rewriterules used ppAssert to obtain early the rewriterules in order
to use them in ppRewrite. But all the simplifications (ex. f x = b :
[f x/b]) are not done at that point. Since --simplification=batch
remove the equality (unlike =incremental), for
reachability_bbttf_eT_arrays.smt2 the answer was sat instead of
unsat (thx Andy).
Partial fix: don't take the rewriterules during ppAssert. That changes
nothing since early rewrite was already disabled. But the complete
fix (when early rewrite will be enabled again) will need to take the
rewriterules more than once.

2. Initial implementation of computeIsConst for arrays - still needs
additional checks based on cardinality
3. Finally fixed pre-competition bug in array rewriter
4. Still to come: array rewrites for constants and STORE_ALL

no explicit setLogic(). This is important for the CVC language, where the parser doesn't ensure that setLogic() is called, and for API uses. setLogicInternal() should be called in order to properly set up heuristics, even if the logic is just ALL_SUPPORTED.
This means that the CVC language can now take advantage of statistics.
Also added the ability to set the logic from CVC presentation language via (e.g.)
OPTION "logic" "QF_UFLIA";
Disabled the justification decision heuristic for ALL_SUPPORTED, as it interferes with incrementality. Kshitij may have a fix (I warned him about this commit).

* arrays now uses the new approach by using a CDQueue<>
* uf strong solver has had the feature disabled, pending a merge from Andy
* theory kinds files now have a getNextDecisionRequest property (if you want to take part in such decision requests you have to list that property)
* the staticLearning property has been renamed ppStaticLearn to match the function name
* theory kinds files are now checked again for correctly-declared properties (this had been disabled)
* minor documentation and other fixups

* more uniform interface between the CLN and GMP wrappers
* support base inference (base == 0) on parsing strings with the CLN wrapper; this was a difference from the GMP wrapper (resolves bug #372)
