2012-10-03adding ::getBooleanVariables to the PropEngineDejan Jovanović
you can get the Boolean variables in the TheoryEngine now by using d_propEngine->getBooleanVariables
2012-07-31Options merge. This commit:Morgan Deters
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.
2012-06-11Merge from quantifiers2-trunkmerge branch.Morgan Deters
Adds TheoryQuantifiers and TheoryRewriteRules, QuantifiersEngine, and other infrastructure. Adds theory instantiators to many theories. Adds the UF strong solver.
2012-06-07LogicInfo locking implemented, and some initialization-order issues in ↵Morgan Deters
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.

2012-03-01Partial merge from kind-backend branch, including Minisat and CNF work toMorgan Deters
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: http://church.cims.nyu.edu/regress-results/compare_jobs.php?job_id=3705&reference_id=3697&mode=&category=&p=5 Note that there are crashes, but that these are exhibited in the nightly regression run too!
2012-02-25Refactored CnfStream to work with the bv theory Bitblaster:Liana Hadarean
* separated SatSolverInput interface class into two classes: - TheoryProxy for the sat solver to communicate with the theories - SatSolverInterface abstract class to communicate with the sat solver * instead of using #ifdef typedef for SatClauses and SatLiterals, now there are CVC4 SatLiteral/SatClause types and mappings between them and the internal sat solver clause/literal representation * added abstract classes for DPLLSatSolver and BVSatSolver different interfaces Replaced TheoryBV with bitblasting implementation: * all operators bitblasted * only operator elimination rewrite rules so far

2011-09-02Merge from my post-smtcomp branch. Includes:Morgan Deters
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.

2011-07-09surprize surprizeDejan Jovanović
2011-04-01This commit is a merge from the "betterstats" branch, which:Morgan Deters
* Makes Options an "omnipresent thread-local global" (like the notion of the "current NodeManager" was already). Options::current() accesses this structure. * Removes Options from constructors and data structures everywhere (this cleans up a lot of things). * No longer uses StatisticsRegistry statically. An instance of the registry is created and linked to a NodeManager. * StatisticsRegistry::current() is similar to Options::current(), but the pointer is stowed in the NodeManager (rather than stored) * The static functions of StatisticsRegistry have been left, for backward compatibility; they now use the "current" statistics registry. * SmtEngine::getStatisticsRegistry() is a public accessor for the registry; this is needed by main() to reach in and get the registry, for flushing statistics at the end.

2010-10-21* Option --no-type-checking now disables type checks in SmtEngineChristopher L. Conway
* Adding options --lazy-type-checking and --eager-type-checking to control type checking in NodeBuilder, which can now be enabled in production mode and disabled in debug mode * Option --no-checking implies --no-type-checking * Adding constructor SmtEngine(ExprManager* em) that uses default options
2010-10-10additional model gen and SMT-LIBv2 compliance work: (get-assignment) now ↵Morgan Deters
supported; work on Result type (biggest noticeable change is that CVC4 now outputs lowercase "sat" and "unsat"), Options class moved to src/smt, to allow for future work on runtime configuration via (set-option) command
2010-10-09Model generation for arith, boolean, and uf theories viaMorgan Deters
(get-value ...) SMT-LIBv2 command. As per SMT-LIBv2 spec, you must pass --interactive --produce-models on the command line (although they don't currently make us do any extra work). Closes bug #213.
2010-06-18Merging the statistics branch into the main trunk. I'll go over how to use ↵Tim King
this Tuesday during the meeting. You'll need to run autogen and receonfigure after updating.
2010-06-04** Don't fear the files-changed list, almost all changes are in the **Morgan Deters
** file-level documentation at the top of the sources. ** This is the "make bugzilla stop bugging me" bugfix commit. * Remove BackedNodeBuilder<> and collapse NodeBuilder<> hierarchy. Updated documentation in the file. Resolves bug #99. * Convenience NodeBuilders (PlusNodeBuilder, OrNodeBuilder, etc.) moved into a separate file. Partially resolves bug #100. * Moved isAssociative(Kind) into kind.h (and into the CVC4::kind namespace) instead of metakind.h (where it was in CVC4::metakind). This clears up a warning (private #inclusion) from the SMT and SMT2 parsers, and maybe makes more sense anyways, since this is based on the kind (and not the metakind) of an operator. * Documentation improvement; doxygen top-level \file gestures, \brief gestures for files, etc. Changed contrib/update-copyright.pl for this change, and post-processed to add \brief. Resolves bug #98. * Removed ExprManager::mkExpr(Kind) and NodeManager::mkNode(Kind). They no longer made sense. Resolves bug #91.
2010-05-25Some initial changes to allow for lemmas on demand. Dejan Jovanović
To be done: * Add erasable map Clause* to bool to minisat (backtracks with the solver) * Add map from Clause* to Node (clauses that came from a node) * Add reference counting Literal -> Node to CNFManager * If Literal -> Node refcount goes to zero, the clauses of Node can be erased (if eresable) * If clause is erased for each L in clause L -> Node refcount goes down
2010-05-14Adding debugging code in PropEngine/CnfStreamChristopher L. Conway
2010-04-01PARSER STUFF:Morgan Deters
* Other minor changes to the new parser to match coding guidelines, add documentation, .... * Add CFLAGS stuff to configure.ac parser Makefile.ams. This ensures that profiling, coverage, optimization, debugging, and warning level options will apply to the new parser as well (which is in C, not C++). This fixes the deprecated warning we were seeing this evening. * Now, if you have ANTLR_HOME set in your environment, you don't need to specify --with-antlr-dir to ./configure or have libantlr3c installed in standard places. --with-antlr-dir still overrides $ANTLR_HOME, and if the installation in $ANTLR_HOME is missing or doesn't work, the standard places are still tried. * Extend "silent make" to new parser stuff. * Added src/parser/bounded_token_buffer.{h,cpp} to the list of exclusions in contrib/update-copyright.pl and mention them as excluded from CVC4 copyright in COPYING. They are antlr3-derived works, covered under a BSD license. OTHER STUFF: * expr_manager.h, expr.h, expr_manager.cpp, and expr.cpp are now auto-generated by a "mkexpr" script. This provides the correct instantiations of mkConst() for public use, e.g., by the parser. * Fix doxygen documentation in expr, expr_manager.. closes bug #35 * Node::isAtomic() implemented in a better way, based on theory kinds files. Fixes bug #40. To support this, a "nonatomic_operator" command has been added. All other "parameterized" or "operator" kinds are atomic. * Added expr_black test * Remove kind::TRUE and kind::FALSE and make a new CONST_BOOLEAN kind that takes a "bool" payload; for example, to make "true" you now do nodeManager->mkConst(true). * Make new "cvc4_public.h" and "cvc4parser_public.h" headers. Private headers should include "cvc4_private.h" (resp. "cvc4parser_private.h"), which existed previously. Public headers should include the others. **No one** should include the autoheader #include (which has been renamed "cvc4autoconfig.h") directly, and public CVC4 headers can't access its #defines. This is to avoid us having the same distribution problem as libantlr3c. * Preliminary fixes based on Tim's code review of attributes (bug #61). This includes splitting hairy template internals into attribute_internals.h, for which another code review ticket will be opened. Bug is still outstanding, but pending further refactoring/documentation. * Some *HashFcns renamed to *HashStrategy to match refactoring done elsewhere (done by Chris?) earlier this week. * Simplified creation of make rules for generated files (expr.cpp, expr.h, expr_manager.cpp, expr_manager.h, theoryof_table.h, kind.h, metakind.h). * CVC4::Configuration interface and implementation split (so private stuff doesn't leak into public headers). * Some documentation/code formatting fixes. * Add required versions of autotools to autogen.sh. * src/expr/mkmetakind: fix a nonportable thing in invocation of "expr" that was causing warnings on Red Hat. * src/context/cdmap.h: add workaround to what appears to be a g++ 4.1 parsing bug.
2010-03-12* Added shutdown() functions to SmtEngine, TheoryEngine, PropEngine,Morgan Deters
DecisionEngine, and Theory. These are triggered from the SmtEngine dtor before the other engines are deleted. This is important because of potential issues with outstanding TNodes in Theory implementations (which fail if the destruction is done in the wrong order, in certain cases). * Favor "FactQueueResetter" instead of clearAssertionQueues() for resetting facts queue in Theory implementations. * Better theory-rewriting code. * Minor cleanups.

2010-03-03Some SAT stuff, not doing anything special yet, just to keep it in sync.Dejan Jovanović
2010-02-26* test/unit/context/context_black.h: Test CDList<>. In particular,Morgan Deters
test behavior of grow(), which was previously very broken, fixed by Tim earlier this afternoon. * add the notion of a "private header". Private header files (those not intended for distribution) should now #include "cvc4_private.h" (or "cvc4parser_private.h" for the parser code). When not actually building libcvc4 (resp. libcvc4parser), or associated unit tests, a warning is emitted by the preprocessor. This should make it easier to notice (and disentangle early) any unwanted public/private mixing. Currently the warning identifies a couple places where we need to fix things. * added directory infrastructure for arrays and BV theories. * the Theory inheritance hierarchy makes some assumptions about the way inheritance is done. These are checked at runtime when CVC4_ASSERTIONS is on. See src/theory/theory.h's TheoryImpl<> definition for details. * src/theory/booleans/theory_bool.h, src/theory/booleans/theory_def.h, src/theory/arith/theory_arith.h, src/theory/arith/theory_def.h, src/theory/uf/theory_uf.h, src/theory/uf/theory_def.h, src/parser/antlr_parser.h: minor code formatting fixes as per policy. * src/theory/uf/theory_uf.cpp: fix for non-debug builds. * src/util/options.h, src/util/model.h, src/util/result.h, src/expr/type.h: make CVC4_PUBLIC. * src/util/decision_engine.h: no longer CVC4_PUBLIC. * src/expr/expr_manager.cpp: ExprManager::booleanType() and ExprManager::kindType() weren't returning a value ?! Fixed. * src/expr/expr_manager.h, src/expr/node_manager.h: ExprManager no longer depends on NodeManager (public/private interface mixing). ExprManagerScope is an internal implementation detail, and is moved to node_manager.h. * src/expr/node.h: mark gdb debug routines as "used" so that GCC always emits code for them (even though its static analysis shows they're unused).
2010-02-25* src/expr/node.h: add a copy constructor. Apparently GCC doesn'tMorgan Deters
recognize an instantiation of the join conversion/copy ctor with ref_count = ref_count_1 as a copy constructor. Problems with reference counts ensue. * src/theory/theory.h, src/theory/theory.cpp: Theory base implementation work. Changed from continuation-style theory calls to having an data member for the output channel. registerTerm() and preRegisterTerm() work. * src/theory/output_channel.h, src/theory/theory.h, src/theory/theory.cpp, src/theory/uf/theory_uf.h, src/theory/uf/theory_uf.cpp: merged ExplainOutputChannel into OutputChannel. * test/unit/expr/node_black.h: remove testPlusNode(), testUMinusNode(), testMultNode(). * src/expr/attribute.h: new facilities ManagedAttribute<> and CDAttribute<>, and add new template parameters to Attribute<>. Make CDAttribute<>s work with context manager. * src/expr/attribute.h, src/expr/node_manager.h: VarNameAttr and TypeAttr are now "owned" (defined) by the NodeManager. The AttributeManager knows nothing of specific attributes, it just as all the code for dealing generically with attributes. * test/unit/expr/node_white.h: test new attribute facilities. * src/expr/soft_node.h: removed: We now have TNode, so SoftNode goes away. * src/theory/Makefile.am: fixed improper linking of theories * src/theory/theory_engine.h: some implementation work (mainly stubs for now, just to make sure TheoryUF can be instantiated properly, etc.) * src/expr/node_value.cpp, src/expr/node_value.h: move a number of function implementations to the header and make them inline * src/expr/node_manager.cpp, src/expr/node_manager.h: move a number of function implementations to the header and make them inline * src/theory/theoryof_table_prologue.h, src/theory/theoryof_table_epilogue.h, src/theory/mktheoryof, src/theory/Makefile.am: make the theoryOf() table from kinds and implement TheoryEngine::theoryOf(). * src/theory/arith/Makefile, src/theory/bool/Makefile: generated these stub Makefiles (with contrib/addsourcedir) as per policy * src/theory/arith, src/theory/bool [directory properties]: add .deps to svn:ignore. * contrib/configure-in-place: permit configuring "in-place" in the source directory. * contrib/get-authors, contrib/dimacs_to_smt.pl, contrib/update-copyright.pl, contrib/get-authors, contrib/addsourcedir, src/expr/mkkind: copyright notice * src/expr/node_manager.h, src/expr/node_builder.h, src/prop/prop_engine.h, src/prop/prop_engine.cpp, src/theory/theory_engine.h, src/smt/smt_engine.h, src/smt/smt_engine.cpp, src/theory/output_channel.h: turn "const Node&"-typed formal parameters into "TNode" * src/theory/bool, src/theory/booleans: "bool" directory renamed "booleans" to avoid keyword clash on containing namespace * src/theory/booleans/theory_def.h, src/theory/uf/theory_def.h, src/theory/arith/theory_def.h: "define" a theory simply (for automatic theoryOf() generator). * src/Makefile.am: build theory subdirectory before prop, smt, etc. so that src/theory/theoryof_table.h header gets generated before it's needed * src/expr/node_prologue.h, src/expr/node_middle.h: move "Kind" into a separate CVC4::kind namespace to avoid its contents from cluttering the CVC4 root namespace. Import the symbol "Kind" into the CVC4 namespace but not the enum values. * src/expr/node_manager.h, src/expr/node.h, src/expr/node_value.h, src/expr/node_value.cpp, src/expr/expr.cpp, src/theory/uf/theory_uf.cpp, src/prop/cnf_stream.cpp, src/parser/smt/smt_parser.g, src/parser/cvc/cvc_parser.g, src/parser/antlr_parser.cpp, test/unit/expr/node_white.h, test/unit/expr/node_black.h, test/unit/expr/kind_black.h, test/unit/expr/node_builder_black.h: update for having moved Kind into CVC4::kind. * src/parser/parser.cpp: added file-does-not-exist check (was failing silently).
2010-02-22* configure.ac: Remove doc/ from search path for Makefile.amsMorgan Deters
* configure.ac, test/unit/Makefile.am: Resolved an issue where even when not testing, one unit test was built. * Re-ran contrib/update-copyright.pl on all source files to ensure consistent and correct header comments. * contrib/get-authors: Change definition of "minor contributor" to >= 10% of lines (rather than strictly greater than 10% of lines)
2010-02-09Changes to the CNF conversion and the SAT solver. All regression pass now, ↵Dejan Jovanović
and we're ready for nightly testing. We should not add regression tests that test future behaviour, as the builds will nag for all failing regressions. Thus, I've separated the multi-query regressions into multiple regressions until the cnf/context/sat is able to handle it. Also, fixed a typo in the CVC parser.
