equality engine through the setMasterEqualityEngine method. This is a read-only equality engine, so nothing should be added to it directly. Instead each equality engine that is of interest should have the master equality engine attached to it. To set when to use the master equality engine see TheoryEngine::finishInit().

ALL_SUPPORTED logic
* Java bindings fixes: fixed access to ostreams, iterators
* Make SmtEngine::setUserAttribute() (and others) take a const string&
* Also a few compliance fixes

unknown because of incompleteness. Other unknown results are not safe to build models for, timeout, interrupted, etc.

CVC4 now produces equivalent output when dumping the SMT1 and SMT2 attachments to that bug report.
This also fixes a memory leak in the new-variable-notification mechanism.

explains why my build was giving different answers from Dejan's build).
Problem was that if you run:
cvc4 --check-models foo.smt
it would fail, but if you run
cvc4 --check-models --produce-models foo.smt
it would succeed. Even though produce-models is supposed to be automatically
set when you set check-models, it seems this was happening too late. Fixed by
removing any distinction between produce-models and check-models in the
heuristic setting code. Kind of ugly though.
Also, disable models if nonlinear arithmetic is on.

LogicException for errors where the user uses a feature not permitted in the current logic (e.g., a quantifier in a QF logic)

ITEs of the form:
IF (denom = 0) THEN divByZero(num) ELSE (DIVISION_TOTAL num denom) ENDIF
where divByZero is an uninterpreted function symbol (there's one for each of the partial operators).
In linear logics, don't do any of this.
Bitvector partial functions to come, if this is successful for Tim.

with --check-models (which caused the same bug, for a different reason,
due to some unintended interaction between the checkModel() function and
the UserContext, which rolled back the Model object. (Groan...)

just the header comments at the top, though. Don't update to this rev if
you don't have time for a complete rebuild, and exclude this rev if you

Also fix bug 421 relating to incrementality and models.
(this commit was certified error- and warning-free by the test-and-commit script.)
|

* fix minor issue with s-expr parsing in CVC and SMT grammars
* other minor things
(this commit was certified error- and warning-free by the test-and-commit script.)

(rather than SAT context)
* Enable part of CVC3 system test (resolves bug 375)
* Fix infinite recursion in beta reduction code (resolves bug 417)
* Some model-building assertions have been added
* Other minor changes
(this commit was certified error- and warning-free by the test-and-commit script.)
|
|
* more minor cleanup/doc
(this commit was certified error- and warning-free by the test-and-commit script.)
|
|
* Remove defunct --no-theory-registration option
* Point people to Wiki tutorial
* Modernize the cut-release script
* Misc cleanup, documentation
(this commit was certified error- and warning-free by the test-and-commit script.)
|
|
* Fix error message if you POP beyond the bottom user stack frame.
(this commit was certified error- and warning-free by the test-and-commit script.)
|
|
* ITE removal fixed to be context-dependent (on UserContext).
Resolves incrementality bugs 376 and 396 (which had given wrong answers).
* some bugfixes for incrementality that Dejan found (fixes bug 394)
* fix for bug in SmtEngine::getValue() where definitions weren't respected
(partially resolves bug 411, but get-model is still broken).
* change status of microwave21.ec.minimized.smt2 (it's actually unsat, but
was labeled sat); re-enable it for "make regress"
Also:
* --check-model doesn't fail if quantified assertions don't simplify away.
* fix some examples, and the Java system test, for the disappearance of the
BoolExpr class
* add copy constructor to array type enumerator (the type enumerator
framework requires copy ctors, and the automatically-generated copy ctor
was copying pointers that were then deleted, leaving dangling pointers in
the copy and causing segfaults)
* --dump=assertions now implies --dump=skolems
* --dump=assertions:pre-<PASS> and --dump=assertions:post-<PASS> now allow
you to dump before/after a particular preprocessing pass. E.g.,
--dump=assertions:pre-ite-removal or --dump=assertions:post-static-learning.
"--dump=assertions" by itself is after all preprocessing, just before CNF
conversion.
* minor fixes to dumping output
* include Model in language bindings
Minor refactoring/misc:
* fix compiler warning in src/theory/model.cpp
* remove unnecessary SmtEngine::printModel().
* mkoptions script doesn't give progress output if stdout isn't a terminal
(e.g., if it's written to a log, or piped through less(1), or whatever).
* add some type enumerator unit tests
* de-emphasize --parse-only and --preprocess-only (they aren't really "common"
options)
* fix some exception throw() specifications in SmtEngine
* minor documentation clarifications

you can get the Boolean variables in the TheoryEngine now by using d_propEngine->getBooleanVariables

declare-const
declare-funs
declare-preds
define
simplify
* don't output --help on bad options, just invite user to try --help
* Datatypes from SMT2 parser now name the tester is-cons (e.g.)
* unknown results produce models, --check-model doesn't fail hard for
incorrect unknown models. removed the assert that kept arithmetic
from producing models if it saw nonlinear

Other changes:

|
* Internal uses of CheckArgument changed to AssertArgument/AlwaysAssertArgument()
* Make util/Assert.h cvc4_private instead of public, so AssertionException and friends are now internal-only
* CheckArgument() throws non-AssertionException
* things outside the core library (parsers, driver) use regular C-style assert,
or a public exception type.
* auto-generated documentation for Smt options and internal options
Also, a small fix to SMT-LIBv1 QF_ABV and QF_AUFBV definitions, which were nonstandard.
