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.)
|
|
* ALL_SUPPORTED/QF_ALL_SUPPORTED don't include nonlinear
* Change "Notice" to "Warning" when produce-models turned off due to non-linear
(this commit was certified error- and warning-free by the test-and-commit script.)
|
|
* 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()"
(this commit was certified error- and warning-free by the test-and-commit script.)

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.

* Ensure Rewriter::init() is called before ::rewrite().
The array type enumerator recently gave us an end-run around
::init(). TheoryEngine no longer calls these, they're done
via static initialization.
* Respect scope for declare-sort/declare-fun/define-sort/define-fun... (resolves bug 412).
(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
|
|
make it unambiguous for case-insensitive filesystems like on Mac. Fixes Mac builds
|
|
* 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.
|
|
* Change --lang smt to mean SMT-LIBv2
* --lang smt1 now means SMT-LIBv1
* SMT-LIBv2 parser now gives helpful error if input looks like v1
* SMT-LIBv1 parser now gives helpful error if input looks like v2
* CVC presentation language parser now gives helpful error if input
looks like either SMT-LIB v1 or v2
* Other associated changes

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.

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
|

* 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.

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).

itself a CONSTANT.
|

* 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)
|
|
* rename DeclarationScope to SymbolTable
* rename all HashStrategy -> HashFunction (which we often have anyways)
* remove CDCircList (no one is currently using it)

1. changes the way options are declared (see http://church.cims.nyu.edu/wiki/Options)
2. moves module-specific options enumerations (SimplificationMode, DecisionMode, ArithUnateLemmaMode, etc.) to their own header files, also they are no longer inside the Options:: class namespace.
3. includes many SMT-LIBv2 compliance fixes, especially to (set-option..) and (get-option..)
The biggest syntactical changes (outside of adding new options) you'll notice are in accessing and setting options:
* to access an option, write (e.g.) options::unconstrainedSimp() instead of Options::current()->unconstrainedSimp.
* to determine if an option value was set by the user, check (e.g.) options::unconstrainedSimp.wasSetByUser().
* ensure that you have the option available (you have to #include the right module's options.h file, e.g. #include "theory/uf/options.h" for UF options)
*** this point is important. If you access an option and it tells you the option doesn't exist, you aren't #including the appropriate options.h header file ***
Note that if you want an option to be directly set (i.e., other than via command-line parsing or SmtEngine::setOption()), you need to mark the option :read-write in its options file (otherwise it's read-only), and you then write (e.g.) options::unconstrainedSimp.set(true).
Adding new options is incredibly simple for primitive types (int, unsigned, bool, string, double). For option settings that you need to turn into a member of an enumerated type, you write a custom "handler" for the option---this is no additional work than it was before, and there are many examples to copy from (a good one is stringToSimplificationMode() in src/smt/options_handlers.h).
Benefits of the new options system include:
1. changes to options declarations don't require a full-source rebuild (you only have to rebuild those sources that depend on the set of options that changed).
2. lots of sanity checks (that the same option isn't declared twice, that option values are in range for their type, that all options are documented properly, etc.)
3. consistency: Boolean-valued option --foo gets a --no-foo automatically, documentation is generated consistently, the option-parsing matches the documented option name, etc.
4. setting options programmatically via SmtEngine::setOption() is enabled, and behaves the same as command-line equivalents (including checking the value is in range, etc.)
5. the notion of options being "set by the user" is now primitive; you can use (e.g.) options::unconstrainedSimp.wasSetByUser() instead of having to use (and maintain) a separate Boolean option for the purpose
I've taken lots of care not to break anything. Hopefully, I've succeeded in that.

got it in quickly for Andy.
A "fair" version forthcoming.
|
|
(e.g., "make dist" produces a distribution that passes "make dist" and "make check", "make uninstall" actually uninstalls, "make distclean" actually cleans, ...)

Basically, this involves creating a separate StatisticsRegistry for the
ExprManager and for the SmtEngine. Otherwise, theories register the
same statistic twice. This is a larger problem, though, for creating
multiple instances of theories, and that is unaddressed. Still,
separating out the expr statistics into a separate registry is probably
a good idea, since the expr package is somewhat separate anyway (and in
the short term it allows two SmtEngines to co-exist).

support yet for enumerating arrays, or for enumerating non-trivial datatypes.

\file tags corrected, copyright added to files that had it missing, etc.
I ensured that I didn't change any code with this commit, and even tested on the cluster to be doubly sure:

Adds TheoryQuantifiers and TheoryRewriteRules, QuantifiersEngine, and other infrastructure.
Adds theory instantiators to many theories.
Adds the UF strong solver.
