* Fix creation of bound variables in CVC native language parser
* This corrects a problem with misleading model output
(this commit was certified error- and warning-free by the test-and-commit script.)
|
|
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).

* 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.

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
|
|
* add support for mkBoundVar() (BOUND_VAR_LISTs in quantifiers must be bound vars)
|

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).

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.

(extended) SMT command get-model. added collectModelInfo and removed getValue from theory interface. merge also includes major updates to finite model finding module (from CASC), added fmf options, some updates to strong solver and quantifiers engine interface. The test recursion_breaker_black currently fails for me on production builds, Morgan is planning to look into this.

See below for details.
* Fix the "assert" name-collision bug (resolves bug #364).
Our identifiers should never be named "assert", as that's a preprocessor
definition in <assert.h>, which is often #included indirectly (so simply
having a policy of not including <assert.h> isn't good enough---one of
our dependences might include it). It was once the case that we didn't
have anything named "assert", but "assert()" has now crept back in.
Instead, name things "assertFoo()" or similar. Thanks to Tim for the
report.
To fix this, I've changed some of Dejan's circuit-propagator code from
"assert()" to "assertTrue()". Ditto for Andy's explanation manager.
Guys, if you prefer a different name in your code, please change it.
* Fix the incorrect parsing of lets in SMT-LIBv2 parser (resolves bug #365).
Inner lets now shadow outer lets (previously, they incorrectly gave an
error). Additionally, while looking at this, I found that a sequential let
was implemented rather than a parallel let. This is now fixed. Thanks to
Liana for the report.
* Remove ANTLR parser generation warnings in CVC parser (resolves bug #314).
* There were a lot of Debug lines in bitvectors that had embedded toString()
calls. This wasted a LOT of time in debug builds for BV benchmarks
(like in "make regress"). Added if(Debug.isOn(...)) guards; much faster
now.
* Support for building public-facing interface documentation only (as opposed
to all internals documentation). Now "make doc" does the public-facing and
"make doc-internals" does documentation of everything. (Along with changes
to the nightly build script---which will now build and publish both types
of Doxygen documentation---this resolves bug #359).
* Fix the lambda typechecking bug (resolves bug #322). Thanks to Andy for the
report (a long long time ago--sorry).
* The default output language for all streams is now based on the current set
of Options (if there is one). This has been a constant annoyance, especially
when stringstreams are used to construct output. However, it doesn't work
for calls from outside the library, so it's mainly an annoyance-fixer for
CVC4 library code itself.
* Add some CVC4_UNUSED markers to local variables in theory_arith.cpp that
are used only in assertions-enabled builds (and thus give warnings in
production builds). This was briefly discussed at the meeting this week.

condition when reading from stdin. This should completely resolve bug #319.
However, on large inputs especially (like the stp/testcase benchmarks), this inlining feature can speed parsing by 5-10%, at the cost of not supporting interactive sessions on stdin (like in the SMT-COMP application track).
So I updated the submission script and competition build so that
* a competition build with antlr-inlining is built for the main and parallel tracks
* a competition build without antlr-inlining is built for the application track
Again, the effect is only when reading the stdin stream (but that's how SMT-COMP works). For normal (non-competition) builds, we need to support interactive sessions (from e.g. KIND) on stdin, so this inlining is off for all builds except main- and parallel-track competition builds.
Also added a "get-antlr-3.4" script that automatically downloads and locally installs a copy of libantlr3c and the antlr parser generator inside the CVC4 source tree.
Closing bug #319.

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

* SMT-LIBv2 parser now supports (echo...).
* Dump() gestures can now dump EchoCommands in CVC and SMT-LIB formats.
This can make it much easier to interpret output.

the branch arithmetic/remove_const_int.
|
|
Changes include
* fixed term visitor from the bvprop branch
* removed all the warnings from builds -- warnings are there to be noted *NOT* to be used as scribbles
* moved the LogicInfo into the theory constructor
|
|
* Permit "BOOL = BOOL" in CVC language parser (auto-replaced with IFF
internally, except in strict mode).
* SExpr atoms now can be string-, integer-, or rational-valued.
* SmtEngine::setInfo(":status", ...) now properly dumps a
SetBenchmarkStatusCommand rather than a SetInfoCommand.
* Some dumping fixes (resolves bug 313)

support incrementality.
Some clean-up work will likely follow, but the CNF/Minisat stuff should be
left pretty much untouched.
Expected performance change negligible; slightly better on memory:

Note that there are crashes, but that these are exhibited in the nightly
regression run too!

lambdas; resolves bug 294

exceptions are not thrown outside the library. Reflect this in the exit code of the driver. Fixes a bug found by Tim among the nightly regressions.
Also improved error reporting if antlr is unavailable and the parsers need to be generated.

Dumping infrastructure. Can dump preprocessed queries and clauses. Can
also dump queries (for testing with another solver) to see if any conflicts
are missed, T-propagations are missed, all lemmas are T-valid, etc. For a
full list of options see --dump=help.
CUDD building much cleaner.
Documentation and assertion fixes.
Printer improvements, printing of commands in language-defined way, etc.
Typechecker stuff in expr package now autogenerated, no need to manually
edit the expr package when adding a new theory.
CVC3 compatibility layer (builds as libcompat).
SWIG detection and language binding support (infrastructure).
Support for some Z3 extended commands (like datatypes) in SMT-LIBv2 mode
(when not in compliance mode).
Copyright and file headers regenerated.

* Preprocessing-time, non-clausal, Boolean simplification round to
support "quasi-non-linear rewrites" as discussed at last few meetings.
* --simplification=none is the default for now, but we'll probably
change that to --simplification=incremental. --simplification=batch
is also a possibility. See --simplification=help for details.
* RecursionBreaker<T> now uses a hash set for the seen trail.
* Fixes to TLS stuff to support that.
* Fixes to theory and SmtEngine documentation.
* Fixes to stream indentation.
* Other miscellaneous stuff.

constructors for Type and Expr (which existed due to ANTLR limitations). These issues are now handled (as a hack, due to said limitations) in the parser rather than the CVC4 core.

* Type::getCardinality() returns the cardinality for for all types.
Theories give a cardinality in the their kinds file. For
cardinalities that depend on a type argument, a "cardinality
computer" function is named in the kinds file, which takes a
TypeNode and returns its cardinality.
* There's a bitmap for the set of "active theories" in the
TheoryEngine. Theories become "active" when a term that is owned by
them, or whose type is owned by them, is pre-registered (run CVC4
with --verbose to see theory activation). Non-active theories don't
get any calls for check() or propagate() or anything, and if we're
running in single-theory mode, the shared term manager doesn't have
to get involved. This is really important for get() performance
(which can only skimp on walking the entire sub-DAG only if the
theory doesn't require it AND the shared term manager doesn't
require it).
* TheoryEngine now does not call presolve(), registerTerm(),
notifyRestart(), etc., on a Theory if that theory doesn't declare
that property in its kinds file. To avoid coding errors,
mktheorytraits greps the theory header and gives warnings if:
+ the theory appears to declare one of the functions (check,
propagate, etc.) that isn't listed among its kinds file properties
(but probably should be)
+ the theory appears NOT to declare one of the functions listed in
its kinds file properties
* some bounded token stream work
