2012-04-11merge from arrays-clark branchMorgan Deters
2012-04-04 * added propagation as lemmas to TheoryBV:Liana Hadarean
* modified BVMinisat to work incrementally * added more bv regressions
2012-03-22Merged updated version of the bitvector theory:Liana Hadarean
* added simplification rewrites
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
2012-02-15This commit merges into trunk the branch branches/arithmetic/integers2 from ↵Tim King
r2650 to r2779. - This excludes revision 2777. This revision had some strange performance implications and was delaying the merge. - This includes the new DioSolver. The DioSolver can discover conflicts, produce substitutions, and produce cuts. - The DioSolver can be disabled at command line using --disable-dio-solver. - This includes a number of changes to the arithmetic normal form. - The Integer class features a number of new number theoretic function. - This commit includes a few rather loud warning. I will do my best to take care of them today.
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.
2011-04-18Partial 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.
2011-03-20commit for the version of bitvectors that passes all the unit testsDejan Jovanović
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.)

2010-07-03With this commit come a number of changes to build system to supportMorgan Deters
building with CLN or with GMP, the contrib/switch-config script (enabling "fast switching" of different configurations in the same builds/ directory), and also some minor changes. ./configure --with-gmp (or --without-cln) forces building with GMP and doesn't even look for CLN. Configure fails if GMP isn't installed. ./configure --with-cln (or --without-gmp) forces building with CLN and doesn't even look for GMP. Configure fails if CLN isn't installed. ./configure [no arguments] will detect what's installed. CLN is default, if it isn't installed, or is too old, GMP is looked for (and configure fails if neither is available). It is an error to specify --with-gmp --with-cln (or --without-* for both) at the same time. Building with CLN (whether forced or detected) adds a note to the configure output mentioning the fact that the build of CVC4 will be linked against a GPLed library and notifying the user of the --without-cln option. Building with GMP (whether forced or detected) affects the build directory, so CLN and GMP builds are kept separate. ./configure --with-cln debug builds in builds/$arch/debug ./configure --with-gmp debug builds in builds/$arch/debug-gmp The final binaries are linked explicitly against either gmp or cln, but not both. If linked against cln, cln pulls in gmp as a dependency, so the result will be linked against both. === Details that you probably don't care about === The headers src/util/{integer,rational}.h are generated from the corresponding .in versions. A user installing a CVC4-devel package will get the headers for rational and integer that match the library that s/he installs. The preprocessor #defines CVC4_GMP_IMP and CVC4_CLN_IMP are added to cvc4autoconfig.h. Only one is ever #defined. cvc4autoconfig.h doesn't need to be #included directly; you get it through #including cvc4_private.h (or the parser version). AM_CONDITIONALs are also defined so that Makefiles get the cln/gmp configuration. AC_SUBSTs are defined so that public headers (see src/util/{integer,rational}.h.in) can use the setting. *Public* headers that need to depend on the cln/gmp configuration can't use cvc4autoconfig.h, because we're keeping that in the private, internal-only space, never to be installed on users' machines. Here, something special is required, like the configure-level generation of headers that I used for src/util/{integer,rational}.h.in. Tim's Integer and Rational wrappers are the only bits of code that should care which library is used (and also src/util/configuration.h, which gives the user of the library information about how CVC4 is built), and possibly some unit tests (?).
2010-07-02re-generated comment headers of source filesMorgan Deters
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.
2010-06-18Merging 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.

instead of the kind, i.e. Expr op = ..."f"... em.mkExpr(op, children); Operator kinds are automatically associated with the enclosing expression kind in the DSL and generated.
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.
