* 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

* 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.

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.

consistency, error-reporting, and documentation.

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.

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

isConst() and isVar() as appropriate)

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.

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.

search early, not to make decisions
new options.h :)

get bitblasted, it would restart to add the clauses, and loose propagation information.
|
|
|
|
* enables decision heuristic (justification) for QF_BV and QF_AUFBV
* disables a failing regression in aufbv (because of equality engine
assert failure trigerred by above change)
* moves around the init procedure smt_engine
* destruction time issues because of moving this -- still to be fixed,
currently get around by not destucting stuff in driver

were seeing in quantifiers+decision stuff
|
|
* clauses shouldn't be erased when they could be a reason for outside propagation
* propagation of p and !p is ignored as this must lead to a conflict in the subtheory internally
|
|
Adds TheoryQuantifiers and TheoryRewriteRules, QuantifiersEngine, and other infrastructure.
Adds theory instantiators to many theories.
Adds the UF strong solver.
|
|
(no performace or search behavior changes expected)

SmtEngine resolved.
ALL_SUPPORTED and QF_ALL_SUPPORTED logics now supported by SMT-LIB parsers. In SMT-LIBv2, if a (set-logic..) command is missing, ALL_SUPPORTED is assumed, and a warning is issued, as discussed on the cvc4-devel mailing list.

the theory engine immediately. The queue is discharged just before a check().
|
|
* allowing propagation of false literals (handles conflict)
* allowing lemmas during BCP (bug 337)
* UF does direct propagation, without checking for literal value anymore
|
|
|
|
and now term notify handles boolean constants; fixed bug 328
|
|
|
|
* notifications are now through the interface subclass instead of a template
* notifications include constants being merged
* changed contextNotifyObj::notify to contextNotifyObj::contextNotifyPop so it's more descriptive and doesn't clutter methods when subclassed
* sat solver now has explicit methods to make true and false constants
* 0-level literals are removed from explanations of propagations
|
|
Major changes from last merge
* ITEs supported
* Don't share theory lemmas to DE, only assertions
Should probably be noted that 'make regress' doesn't quite
pass with --decision=justification. Throws off search in couple
of arith benchmarks.
No serious performance changes expected. Keep an eye.
|
|
This should also fix bug 325.
|
|
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
|
|
d_sharedTermsExist is now set based on logicInfo instead of dynamically when
shared terms are found.
