2010-12-16minor fixes for correct doxygen outputMorgan Deters
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.)
2010-10-28Changing NodeBuilder::debugCheckType() to maybeCheckType()Christopher L. Conway
Changing NodeManager/ExprManager constructors to take Options
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
2010-10-08* (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!)
2010-09-21Rm'ing automatic type check in NodeBuilder for vars/constantsChristopher L. Conway
2010-09-21Moving automatic type check to NodeBuilder (Fixes: #199)Christopher L. Conway
2010-09-20bitvector rewriting for the core theory and testcasesDejan Jovanović
2010-09-02"Leftist NodeBuilders" are now supported.Morgan Deters
That is, "nb << a << b << c << OR << d << AND" turns into (AND (OR a b c) d) The rule is: pushing a kind onto a NodeBuilder with a nonzero number of child Nodes in it, the action "collapses" it. If a kind is already associated to the NodeBuilder, it is an error. Thus: NodeBuilder<> nb(AND); nb << AND; and NodeBuilder<> nb; nb << AND << OR; are both errors (if assertions are on). In reality, though, the implementation is trickier, as the collapsing is done lazily on the following push. This complicates things a bit, but by placing an Assert(false), I found that we aren't depending on the old behavior (at least for any unit tests or regressions in the source tree). The Assert(false) is now removed and leftist NodeBuilders are in business. Fixes bug 101.
2010-08-17Merge from "cc" branch:Morgan Deters
CongruenceClosure implementation; CongruenceClosure white-box test. New UF theory implementation based on new CC module. This one supports predicates. The two UF implementations exist in parallel (they can be selected at runtime via the new command line option "--uf"). Added type infrastructure for TUPLE. Fixes to unit tests that failed in 16-August-2010 regressions. Needed to instantiate TheoryEngine with an Options structure, and explicitly call ->shutdown() on it before destruction (like the SMTEngine does). Fixed test makefiles to (1) perform all tests even in the presence of failures, (2) give proper summaries of subdirectory tests (e.g. regress0/uf and regress0/precedence) Other minor changes.
2010-07-02* Added white-box TheoryEngine test that tests the rewriterMorgan Deters
* Added regression documentation to test/regress/README * Added ability to print types of vars in expr printouts with iomanipulator Node::printtypes(true)... for example, Warning() << Node::printtypes(true) << n << std::endl; * Types-printing can be specified on the command line with --print-expr-types * Improved type handling facilities and theoryOf(). For now, SORT_TYPE moved from builtin theory to UF theory to match old behavior. * Additional gdb debug functionality. Now we have: debugPrintNode(Node) debugPrintRawNode(Node) debugPrintTNode(TNode) debugPrintRawTNode(TNode) debugPrintTypeNode(TypeNode) debugPrintRawTypeNode(TypeNode) debugPrintNodeValue(NodeValue*) debugPrintRawNodeValue(NodeValue*) they all print a {Node,TNode,NodeValue*} from the debugger. The "Raw" versions print a very low-level AST-like form. The regular versions do the same as operator<<, but force full printing on (no depth-limiting). * Other trivial fixes
2010-06-30* theory "tree" rewriting implemented and worksMorgan Deters
* added TheoryArith::preRewrite() to test and demonstrate the use of pre-rewriting. * array types and type checking now supported * array type checking now supported * theoryOf() dispatching properly to arrays now * theories now required to implement a (simple) identify() function that returns a string identifying them for debugging/user output purposes * added "builtin" theory to hold all built-in kinds and their type rules and rewriting (currently only exploding distinct) * fixed production build failure (regarding NodeSetDepth) * removed an errant "using namespace std" in util/bitvector.h (and made associated trivial fixes elsewhere) * fixes to make unexpected exceptions more verbose in debug builds * fixes to make multiple, cascading assertion fails simpler * minor other fixes to comments etc.
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.
2010-06-03* Added NodeBuilder<>::getChild() to make interface more consistentMorgan Deters
with that of Node. * If NodeBuilder<> hasn't yet been assigned a Kind, several member functions related to children now throw an IllegalArgumentException: * getNumChildren() * begin() * end() * operator[] * getChild() This is because if you later assign the NodeBuilder<> a PARAMETERIZED kind, the children are "reinterpreted" -- the first being an operator. Interface-wise, it doesn't make sense to return one thing for nb[0], then later, after setting the kind, to return another thing for nb[0]. * Fixed unit tests depending on this behavior. * Added a warning to the testing summary if unit tests didn't run (because this is likely due to compilation problems, and without a warning it looks kind of like a test success) * VERBOSE wasn't exported to the environment for unit test "make check." Fixed.
2010-06-01Fixed a bug in partial_model.cpp where the data was immediately deallocated ↵Tim King
before being used. Fixed a bug in node_builder.h's crop where a pointer is dereferenced after a realloc call.
2010-04-26Adding the intermediary TypeNode to represent (and separate) the Types at ↵Dejan Jovanović
the Node level.
2010-04-15Implementing missing NodeBuilder::constructNodeChristopher L. Conway
2010-04-14Marging from types 404:415, changes: MassiveDejan Jovanović
* Types are now represented as nodes in the attribute table and are managed, i.e. you can say Type booleanType = d_nodeManager->booleanType(); Type t = d_nodeManager->mkFunctionType(booleanType, booleanType); FunctionType ft = (FunctionType)t; Assert(ft.getArgTypes()[0], booleanType); * The attributes now have a table for Nodes and a table for TNodes (both should be used with caution) * Changes the way nodes are extracted from NodeBuilder, added several methods to extract a Node, NodeValue, or Node*, with corresponding methods for extraction * Used the above in the construction of Expr and Type objects * The NodeManager now destroys the attributes in the destructor by pausing the garbage collection * To achive destruction a flag d_inDesctruction has been added to loosen the assertion in NodeValue::dec() (there might be -refcount TNodes leftover) * Beginnings of the Bitvector constants using GMP Not yet in tiptop phase, needs more documentation, and Types should be pulled out to TypeNodes eventually. Also, the types are currently defined in the builting_kinds, and I need to add these to the theory specific definitions with special 'type' constructs. I hate branching and merging.
2010-04-14* Better dependency tracking for unit test building and linking, andMorgan Deters
auto-generated headers (metakind.h etc.), so they don't have to be recompiled every time. This drastically improves build time when only small updates are made. * Added "memory.h" unit test header for checking out-of-memory conditions. cdlist_black uses it. * Added helpful output when you "make lcov" in a non-coverage-enabled build. * Removed strict aliasing warning when compiling metakind.h header with optimization on. * Removed const version of NodeBuilder::operator Node()---it was poorly performing, better to not permit it---and fixed the convenience builders to use the non-const version (re: code review #63) * Color-coded test output on capable terminals. * Fixed some warnings in unit tests.
2010-04-04* Addressed issues brought up in Chris's review of Morgan'sMorgan Deters
NodeManager (bug #65). Better documentation, etc. * As part of this, removed NodeManager::mkVar() (which created a variable of unknown type). This requires changes to lots of unit tests, which were using this function. * Performed some review of parser code (my code review #73). + I changed the way exceptions were caught and rethrown in src/parser/input.cpp. + ParserExceptions weren't being properly constructed (d_line and d_column weren't intiialized and could contain junk, leading to weird error messages). Fixed. * Fix to the current working directory used by run_regression script. Makes exceptional output easier to match against (in expected error output). * (configure.ac) Ensure that CFLAGS has -fexceptions in it, in case we compile any C code and don't use the C++ compiler.
2010-04-01reran update-copyright.pl to get new contributors and add new header ↵Morgan Deters
comments to files without them
2010-03-30Highlights of this commit are:Morgan Deters
* add NodeManagerWhite unit test * change kind::APPLY to kind::APPLY_UF * better APPLY handling: operators are no longer considered children * more efficient pool lookup; the NodeValue doesn't have to be as fully constructed for the lookup to proceed * extend DSL for kind declarations + new "theory" command declares a theory and its header. theory_def.h no longer required. + arity enforced on operators + constant mapping, hashing, equality * CONSTANT metakinds supported (via Node::getConst<T>(), for example, Node::getConst<CVC4::Rational>() gets a Rational out of a Node (assuming it is of CONST_RATIONAL kind) * added CONST_RATIONAL and CONST_INTEGER kinds * builtin operators (AND, OR, PLUS, etc..) returned by Node::getOperator() are now CONSTANT metakind and are created by NodeManager * Pretty-printing of Nodes now has a depth limit settable by a stream manipulator (e.g. "cout << Node::setdepth(5) << m << endl;" prints DAG rooted at m to a depth of 5) * getters added to Node, TNode, NodeValue, etc., for operators and metakinds * build-time generators for kind.h, metakind.h, and theoryof_table.h headers now have a simpler design and flag errors better, and the templates (kind_template.h etc.) are easier to understand. * DISTINCT is now a kind, and the SMT parser now passes through DISTINCT nodes instead of blowing them up into ANDs. Until theory rewriting is online, though, DISTINCTs are directly blown up into conjunctions in TheoryEngine::rewrite(). * add gmpxx detection and inclusion * better Asserts throughout, some documentation, cleanup
2010-03-12* src/context/cdmap.h: rename orderedIterator to iterator, do awayMorgan Deters
with old iterator (closes bug #47). * src/context/cdset.h: implemented. * src/expr/node_builder.h: fixed all the strict-aliasing warnings. * Remove Node::hash() and Expr::hash() (they had been aliases for getId()). There's now a NodeValue::internalHash(), for internal expr package purposes only, that doesn't depend on the ID. That's the only hashing of Nodes or Exprs. * Automake-quiet generation of kind.h, theoryof_table.h, and CVC and SMT parsers. * various minor code cleanups.
2010-03-08This fixes regressions at levels >= 1 which were failingMorgan Deters
* implement zombification and garbage collection of NodeValues (but GC not turned on yet) * implement removal of key nodes from all attribute tables * audit NodeBuilder and fix memory leaks and improper reference-count management. This is in many places a re-write. Clearly documented invariants on NodeBuilder state. (Closes Bug 38) * created a "BackedNodeBuilder" that can be used to construct NodeBuilders with a stack-based backing store for a size that's not a compile-time constant. * NodeValues no longer depend on Node for toStream()'ing * make unit test-building "silent" with --enable-silent-rules * (Makefile.am, Makefile.builds.in) fix top-level build system so that "make regressN" works with unbuilt/out-of-date source trees in the expected way. * (various) code cleanup, documentation, formatting
2010-03-08Fixing Debug("prop") => Debug("node") typoDejan Jovanović
2010-03-05* public/private code untangled (smt/smt_engine.h no longer #includesMorgan Deters
expr/node.h). This removes the warnings we had during compilation, and heads off a number of potential linking errors due to improper inlining of private (library-only) stuff in client (out-of-library) code. * "configure" now takes some options as part of a "bare-option" build type (e.g., "./configure debug-coverage" or "./configure production-muzzle"). * split cdo.h, cdlist.h, cdmap.h, and cdset.h from context.h * split cdlist_black unit test from context_black * implement CDMap<>. * give ExprManagers ownership of the context (and have SmtEngine share that one) * fix main driver to properly report file-not-found * fix MemoryMappedInputBuffer class to report reasons for "errno"-returned system errors * src/expr/attribute.h: context-dependent attribute kinds now supported * test/unit/expr/node_white.h: context-dependent attribute tests * src/prop/cnf_conversion.h and associated parts of src/util/options.h and src/main/getopt.cpp: obsolete command-line option, removed. * src/util/Assert.h: assertions are now somewhat more useful (in debug builds, anyway) during stack unwinding. * test/unit/theory/theory_black.h: test context-dependent behavior of registerTerm() attribute for theories * src/expr/node_builder.h: formatting, fixes for arithmetic convenience node builders, check memory allocations * test/unit/expr/node_builder_black.h: add tessts for addition, subtraction, unary minus, and multiplication convenience node builders * src/expr/attribute.h: more comments * (various) code formatting, comment cleanup, added throws specifier to some destructors * contrib/code-checker: prototype perl script to test (some) code policy * contrib/indent-settings: command line for GNU indent to indent using CVC4 style (sort of; this is a work in progress) * COPYING: legal stuff * DESIGN_QUESTIONS: obsolete, removed
2010-03-02* NodeBuilder work: specifically, convenience builders. "a && b && c || d && e"Morgan Deters
(etc.) now work for Nodes a, b, c, d, e. Also refcounting fixes for NodeBuilder in certain cases * (various places) don't overload __gnu_cxx::hash<>, instead provide an explicit hash function to hash_maps and hash_sets. * add a new kind of assert, DtorAssert(), which doesn't throw exceptions (right now it operates like a usual C assert()). For use in destructors. * don't import NodeValue into CVC4 namespace (leave under CVC4::expr::). * fix some Make rule dependencies * reformat node.h as per code formatting policy * added Theory and NodeBuilder unit tests
2010-02-27A bag of unrelated fixes to bring trunk more in-line with recentMorgan Deters
policy discussion (no dead code, no unimplemented unit tests...), and other fixes: * src/expr/node_builder.h: uncomment AndNodeBuilder, OrNodeBuilder, PlusNodeBuilder, and MultNodeBuilder. (These had been dead code for awhile.) * src/expr/node_value.cpp: toString() is much more reasonable now, printing S-exprs and using variable names (instead of printing raw pointer values). Next, we'll want to define a pretty-printing theory interface and perhaps hook this up to that. * test/unit/expr/node_black.h: implement testIterator(), testToString(), and testToStream(). * test/unit/expr/node_builder_black.h: implement testIterator() and testAppend(), and add some code to avoid the warnings on clear() for unused NodeBuilders. * src/expr/node_builder.h: redefine "iterator" to be over Nodes rather than over NodeValues. Doesn't make sense to expose the underlying NodeValues. This shouldn't affect anyone, no one was using NodeBuilder iterators. * fix some comments in source code
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_builder.h: fixed some overly-aggressive refcount decrementing.Morgan Deters
There remain memory leaks (and some over-decrementing of refcounts) that I've identified; another commit forthcoming. * src/expr/attribute.h: keys are now NodeValue* instead of TNode * src/theory/output_channel.h: change OutputChannel::conflict() to the negation of what we had before: it now takes an AND of TRUE literals as a conflict clause rather than an OR of FALSE ones. * src/expr/node.cpp: (non-template) CVC4::expr::debugPrint() routine for use inside gdb * src/expr/node.h: remove Node::debugPrint() member (now a function instead of a member function, since Node is now a template it wasn't being properly instantiated(?) and couldn't be called from gdb) * src/expr/Makefile.am: add node.cpp * src/expr/node_manager.h: code formatting
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).
