Also support array-store-all for Boolean terms (related to abstract values, since that's the only way for the user to include an array-store-all in an assertion).

output correct
models for such functions (though they are somewhat ugly at present).
There's still a problem with model extraction, but it's not Boolean terms' fault.
Sometimes checkModel() can report that the model is just fine, but if a user extracts
values with getValue(), they find problems with the model (i.e., it doesn't satisfy some
assertions). This appears to be due to an asymmetry between how checkModel() works and
how Model::getValue() works. I'll open a bugzilla report to discuss this after thinking
some more on it.

Passes simple tests and doesn't break existing functionality.
Still need some work merged in for models.
This version enables BV except for pure arithmetic (since we might otherwise need Boolean term support, which uses BV). Tonight's nightly regression run should tell us if/how that hurts performance.

Also some fixes to parametric datatypes I found, and fixes for a handful of bugs, including some observed with --check-models --incremental on together.

* remove from public interface (ExprManager, Type)
* CVC parser reports an unimplemented feature error if used
I didn't want to tear it out completely (from NodeManager, TypeNode,
type-checking, pre-processing, etc.) because that's a lot of hassle
and we'll add it back in after the release anyway. It *does* mean
that CVC4::Predicate is in the public interface, but that it can't be
used for anything (by users).

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
(this commit was certified error- and warning-free by the test-and-commit script.)
|
|
** remove a number of warnings in bindings generation
** give appropriate names for operator-overloading
** make sure Java language bindings are built with -fno-strict-aliasing, to ensure the optimizer doesn't produce bad code
* Also remove BitVector::equals(), which wasn't used and was inconsistently implemented (operator==() is still there).

* fixed TypeNode::getBaseType() for predicate subtypes
* added Type::getBaseType() for public interface
* added unit testing
To avoid confusion, also:
* renamed PredicateType::getBaseType() to "getParentType()"
* renamed TypeNode::getSubtypeBaseType() to "getSubtypeParentType()"

discovered (still outstanding). :-(
* Fix a documentation-building problem when building from tarballs (fixes distcheck build failure last night)
* Provide expected output for arith regression 'mod.01.smt2'
* Also, fix a compiler warning in inst_gen.cpp

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
want to see what's new across a range of commits.

Also fix bug 421 relating to incrementality and models.

|
|
* 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.)
|
|
* 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

* respect output lang
* fix export variable for BOUND_VARIABLE
* support export of SUBRANGE_TYPE
* statistic for lastWinner, other minor stat changes
* fix running of multiple threads on checsat/query
* changes of Assert -> assert which became private
* fix some destruction time order issues
* fix Pickler with AssertionException going private
Fixed by not fixing:
* portfolio+datatypes does not work
- added ExportUnsupportedException to more places, switches
to sequential
(still TODO / decide : not switch silently, but print error)
> note: this exception now needs to be (and is) defined in expr.h
Known issues:
* problems in portfolio+quantifiers
- at least some problems appear to be because of static variables
(will be later "fixed" like the datatypes)

* 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.

|
|
* --early-exit and --no-early-exit command line options (the former is default for all builds except debug builds)
* New SEXPR kind for doing lists of things (we previously used TUPLEs for this purpose, but TUPLEs will be used in future by the datatypes theory, and so cannot have function symbols in them, etc.).
* SMT-LIB compliant output for (set-option :produce-unsat-cores true) and (get-unsat-core)

The external interface (e.g., what's answered by ExprManager::getStatistics() and SmtEngine::getStatistics()) is a snapshot of the current statistics (rather than a reference to the actual StatisticsRegistry).
The StatisticsRegistry is now internal-only. However, it's built as a convenience library so that the parser and driver can use it too (by re-linking against it).
This is part of the ongoing effort to clean up the public interface.

meeting last week. The SmtEngine now subscribes to NodeManager events,
does appropriate dumping of variable declarations, and notifies the Model
class.
The way to create a skolem is now:
nodeManager->mkSkolem("myvar_$$", TypeNode, "is a variable created by the theory of Foo")
The first argument is the name of the skolem, and the (optional) "$$" is a
placeholder for the node id (to get a unique name). Without a "$$", a "_$$"
is automatically appended to the given name.
The second argument is the type.
The (optional, but recommended) third argument is a comment, used by the
dump infrastructure to indicate what the variable is for / who owns it.
An optional fourth argument (not shown) allows you to specify flags that
control the behavior (e.g., don't do notification, and/or don't make a
unique name). Look at the documentation for details on these.
In particular, the above means you can't just do a mkSkolem(boolType) for
example---you have to specify a name and (hopefully also,
but it's optional) a comment. This leads to easier debugging than the
anonymous skolems before, since we'll be able to track where the skolems
came from.
Much of the Model and Dump stuff, as well as some Command stuff, is cleaned up
by this commit. Some remains to be cleaned up.

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.
