2012-09-27* Rename SMT parts (printer, parser) to SMT1Morgan Deters
* Change --lang smt to mean SMT-LIBv2 * --lang smt1 now means SMT-LIBv1 * SMT-LIBv2 parser now gives helpful error if input looks like v1 * SMT-LIBv1 parser now gives helpful error if input looks like v2 * CVC presentation language parser now gives helpful error if input looks like either SMT-LIB v1 or v2 * Other associated changes (this commit was certified error- and warning-free by the test-and-commit script.)
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)
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.
2011-04-25Weekend 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
2011-04-20Minor mixed-bag commit. Expected performance impact negligible.Morgan 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.
2010-11-15Pretty-printer infrastructure created (in src/printer) and SMT-LIBv2 printerMorgan Deters
implemented. This new infrastructure removes support for pretty-printing (even in the AST language) an Expr with reference count 0. Previously, this was supported in a few places internally to the expr package, for example in NodeBuilder. (Now, a NodeBuilder cannot be prettyprinted, you must extract the Node before printing it.)
2010-10-08* (define-fun...) now has proper type checking in non-debug buildsMorgan Deters
(resolves bug #212) * also closed some other type checking loopholes in SmtEngine * small fixes to define-sort (resolves bug #214) * infrastructural support for printing expressions in languages other than the internal representation language using an IO manipulator, e.g.: cout << Expr::setlanguage(language::output::LANG_SMTLIB_V2) << expr; main() sets the output language for all streams to correspond to the input language * support delaying type checking in debug builds, so that one can debug the type checker itself (before it was difficult, because debug builds did all the type checking on Node creation!): new command-line flag --no-early-type-checking (only makes sense for debug builds) * disallowed copy-construction of ExprManager and NodeManager, and made other constructors explicit; previously it was easy to unintentionally create duplicate managers, with really weird results (i.e., disappearing attributes!)
