2011-09-29Some base infrastructure for user push/pop; a few bugfixes to user push/pop ↵Morgan Deters
and model gen also. I also expect this commit to fix bug #273. No performance change is expected on regressions with this commit, see http://goedel.cims.nyu.edu/regress-results/compare_jobs.php?job_id=2871&reference_id=2863

2011-09-15additional stuff for sharing, Dejan Jovanović
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.

* compilation fixes for GCC 4.6.x + ptrdiff_t is now in std:: * fix some make rules that are ok in Make 3.81 but broke in Make 3.82 * look for cxxtestgen.py as well as cxxtestgen.pl, and look for cxxtest headers in /usr/include

on some problems---valgrind gave many complaints): the problem was that calloc() (in the Backtracker) wasn't allocating enough space for the type located at the resulting address. Resolves bug #263. Also, some debugging improvements.

2011-05-05Merge from nonclausal-simplification-v2 branch:Morgan Deters
* 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.
2011-05-02Minor fixes to various parts of CVC4, including the removal of the uintptr_t ↵Morgan Deters
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.
2011-05-01minor fixes, plus experimental readline support in InteractiveShellMorgan Deters
2011-04-25Monday tasks:Morgan Deters
* new "well-foundedness" type property (like cardinality) specified in Theory kinds files; specifies well-foundedness and a ground term * well-foundedness / finite checks in Datatypes now superseded by type system isFinite(), isWellFounded(), mkGroundTerm(). * new "RecursionBreaker" template class, a convenient class that keeps a "seen" trail without you having to pass it around (which is difficult in cases of mutual recursion) of the idea of passing around a "seen" trail
2011-04-25Weekend work. The main points:Morgan Deters
* 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
2011-04-23* reviewed BooleanSimplification, added documentation & unit testMorgan Deters

* Fixed hole in arrays typechecking. * Fixed "make dist". * Better ouroborous test, and some printer fixes. * Continued cleanup in CVC parser, removed some warnings. * Better output.
2011-04-20Tuesday end-of-day commit.Morgan Deters
Expected performance impact outside of datatypes/CVC parser is negligible. * CVC language LAMBDA, functional LET, type LET, precedence fixes, bitvectors, and arrays, with partial parsing support also for quantifiers, tuples, subranges, subtypes, and records * support for complex recursive DATATYPE selectors, e.g. tree = node(children:ARRAY INT OF tree) | leaf(data:INT) these are complicated because they have to be left unresolved at parse time and dealt with in a second pass. * bugfix for Exprs/Types that occurred when setting them to null (not Nodes/TypeNodes, just Exprs/Types). * Cleanup/code review items

2011-04-18mostly CVC presentation language parsing and printingMorgan Deters
2011-04-18Partial merge from datatypes-merge branch:Morgan Deters
1. Defines a new type "DatatypeType", a type-constant that holds a Datatype, describing an inductive data type. 2. CVC language parser supports datatypes. 3. CVC language printer now functional. 4. Minor other cleanups. No performance impact is expected outside of datatypes. I'm verifying that that is the case with a cluster job this morning.
2011-04-15partial merge from portfolio branch, adding conversions ↵Morgan Deters

Also, only build doxygen documentation on stuff in src/, not test/ or contrib/ or anywhere else. Hopefully this turns our 3000+ page user manual into something a little more useful!
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.
2011-03-30Add Valuation::getSatValue() so that theories can access the currentMorgan Deters
(propositional) assignment for theory atoms. Fixed Debug/Trace as discussed in bug ticket #252 and on the mailing list. This implementation leads to some compiler warnings in production builds, but these will be corrected in coming days. There appears to be a small speedup in the parser as a result of this fix: http://goedel.cims.nyu.edu/regress-results/compare_jobs.php?job_id=1902&reference_id=1886&p=5 Cleaned up a few CD Boolean attribute things. Various small fixes to coding guidelines / test coverage. This commit: * Resolves bug 252 (tracing not disabled in production builds) * Resolves bug 254 (implement CDAttrHash<>::BitIterator::find())

2011-03-25This is a merge from the "theoryfixes+cdattrhash" branch. The changesMorgan Deters
are somewhat disparate but belonged on the same branch because they were held back from trunk all for the same reason (to keep the trunk stable for furious bitvector development). Dejan has now given me the go-ahead for a merge. ========================================= THIS COMMIT CHANGES THE THEORY INTERFACE! ========================================= Theory constructors are expected to take an additional "Valuation*" parameter that each Theory should send along to the base class constructor. The base class Theory keeps the Valuation* in a d_valuation field for use by it and by its derived classes. Theory::getValue() no longer takes a Valuation* (it is expected to use d_valuation instead). This allows other theory functions to take advantage of getValue() for debugging or heuristic purposes. TODO BEFORE MERGE TO TRUNK: ****implement BitIterator find() in CDAttrHash<bool>. Specifically: * Added QF_BV support for SMT-LIB v2. * Two adjustments to the theory interface as requested by Tim King: 1. As described above. 2. Theories now have const access to the fact queue through base class functions facts_begin() and facts_end(); useful for debugging. * Added an "Asserted" attribute so that theories can check if something has been asserted or not (and therefore not propagate it). However, this has been disabled for now, pending more data on the overhead of it, and pending discussion at the 3/25/2011 meeting. * Do not define NDEBUG in MiniSat in assertion-enabled builds (so that MiniSat asserts are evaluated). * As a result of the new MiniSat assertions, some --incremental regressions had to be disabled; also, some bitvectors ?!! * Bug 71 is resolved by adding a specialization for CDAttrHash<> in the attribute package. * Fixes for some warnings flagged by clang. * System tests have arrived! So far mainly infrastructure for having system tests, but there is a system test aimed at improving code coverage of the printer package. * Minor other adjustments to documentation and coding to be more conformant to CVC4 policy. Tests have been performed to demonstrate that these changes have no or negligible effect on performance. In particular, changing the CDAttrHash<> doesn't have any real effect on performance or memory right now, since there is only one context-dependent boolean flag (as soon as another is added, the effect is noticeable but probably still slight).
2011-03-15Merge from cudd branch. This mostly just adds support for linkingMorgan Deters
against cudd libraries, the propositional_query class (in util/), which uses cudd if it's available (and otherwise answers UNKNOWN for all queries), and the arith theory support for it (currently disabled per Tim's request, so he can clean it up). Other changes include: * contrib/debug-keys - script to print all used keys under Debug(), Trace() * test/regress/run_regression - minor fix (don't export a variable) * configure.ac - replace a comment removed by dejan's google perf commit * some minor copyright/documentation updates, and minor changes to source text to make 'clang --analyze' happy.
2011-03-14Fix to bug 251 (non-spurious warnings in builds) by shifting metakind array ↵Morgan Deters
by 1 to handle the UNDEFINED_KIND case.
2011-02-28Review of mktheorytraits, mkrewriter, and recent changes to other mk* ↵Morgan Deters
scripts. Minor changes only, correcting some documentation and fixing some warnings that were being issued about functions not existing.
