2012-08-07Some items from the CVC4 public interface review:Morgan Deters
* rename DeclarationScope to SymbolTable * rename all HashStrategy -> HashFunction (which we often have anyways) * remove CDCircList (no one is currently using it)
2012-08-03ArrayStoreAll infrastructureMorgan Deters
2012-08-03fix uses of getMetaKind() from outside the expr package. (they now use ↵Morgan Deters
isConst() and isVar() as appropriate) also some base infrastructure for the new ::isConst().

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.
2012-07-27Minor cleanup after today's commits:Morgan Deters
* change some uses of "std::cout" to "Message()" * change some files to use Unix newlines instead of DOS newlines * fix compiler warning

2012-07-27Merge quantifiers2-trunk:François Bobot
- new syntax for rewrite rules - better rewrite rules theory - remove the rewriting with rewrite rules during ppRewrite temporarily - theory can define their own candidate generator - define a general candidate generator (inefficient ask to every theory) - split inst_match between the pattern matching used for quantifiers (inst_match.*) and the one used for rewrite rules (rr_inst_match.*): - the pattern matching is less exhaustive for quantifiers, - the one for rewrite rules can use efficient-e-matching.
2012-07-18removing output operator for SExprTypes, which is never used (and SExprTypes ↵Morgan Deters
is not public-facing)---this fixes the language bindings, which fixes the broken debian build overnight
2012-07-17SMT-LIBv2 compliance updates:Morgan Deters
* more correct support for get-info responses * printer infrastructure extended to SExprs * parser updates to correctly handle symbols and strings (there were some minor differences from the spec)
2012-07-16Support for having two SmtEngines with the same ExprManager.Morgan Deters
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).
2012-07-14Type enumerator infrastructure and uninterpreted constant support. No ↵Morgan Deters
support yet for enumerating arrays, or for enumerating non-trivial datatypes.
2012-07-12merged fmf-devel branch, includes support for SMT2 command get-value and ↵Andrew Reynolds
(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.
2012-07-10small changes:Dejan Jovanović
* smtlib2 decimal constant can be "1.", i.e. doesn't need digits after the point * adding CVC4_PUBLIC to rational output operator, otherwise it's unusable for users
2012-07-08Bugs resolved by this commit: #314, #322, #359, #364, #365.Morgan Deters
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.
2012-07-07Various fixes to documentation---typos, some incomplete documentation fixed, ↵Morgan Deters
\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: http://church.cims.nyu.edu/regress-results/compare_jobs.php?job_id=4655&reference_id=4646&p=0
2012-06-22TPTP: add parser for cnf and fofFrançois Bobot
- include directive works - no keyword : 'fof', 'cnf', ... can be used for symbols name - real -> unsorted -> real (for the one that appear, so no bijection bitween real and unsorted) - same thing for string But: - string not distinct by projection to real, not sure if the current state of string theory make them distinct - filtering in include is not done - the result is not printed in the TPTP way (currently SMT2 way)

Adds TheoryQuantifiers and TheoryRewriteRules, QuantifiersEngine, and other infrastructure. Adds theory instantiators to many theories. Adds the UF strong solver.
2012-06-09Cleanup and comments for the dag-ifier. Also some unit testing for it.Morgan Deters
2012-06-09Dagification of output expressions.Morgan Deters
By default, common subexpressions are dagified if they appear > 1 time and are not constants or variables. This can be changed with --default-expr-dag=N --- N is a threshold such that if the subexpression occurs > N times, it is dagified; a setting of 0 turns off dagification entirely. If you notice strange dumping behavior (taking too long to print anything, e.g.), revert to the old behavior with --default-expr-dag=0 and let me know of the problem.
2012-06-08The option --arith-presolve-lemmas had previously been renamed --unate-lemmas.Morgan Deters
This commit just renames it in --help documentation, etc.
2012-06-08Extend Printer infrastructure also to the "Result" class, meaning that ↵Morgan Deters
different output languages can write "sat", "unsat", etc., in different ways. No output is changed by this commit, but the flexibility is added that Francois wanted at today's meeting.

the unconstrained examples in QF_AUFBV/brummayerbiere3 - should also help generally on at least BV and maybe others. Off by default for now - results are mixed and it's hard to evaluate with so many existing assertion failures and segfaults - will re-evaluate once those are fixed

2012-05-09* simplifying equality engine interfaceDejan Jovanović
* 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
2012-05-09Merge from decision branch (ITE support)Kshitij Bansal
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.
2012-05-09Fixing the debug tags generation and related methods in configuration.cpp ↵Dejan Jovanović
that disallowed me to debug my bugs by reporting that the debug tag doesn't exists, where in fact it was in the code. 1) The grep and sed for tags wasn't picking up on .isOn("tag") 2) The isDebugTag a) didn't take a parameter b) was using binary search using strcmp which is non-portable and didn't work for tags including special characters Morgan should vet this, since there is some crazy sed stuff going on
