and arith.
|
|
instantiation strategies moved from instantiators to central instantiation engine, removed instantiator objects, simplified rewrite rules candidate generator to use central equality engine, efficient e-matching now uses central equality engine
|
|
|
|
numerous bugfixes, and the cvc3 system test is enabled.
|
|
* arrays now uses the new approach by using a CDQueue<>
* uf strong solver has had the feature disabled, pending a merge from Andy
* theory kinds files now have a getNextDecisionRequest property (if you want to take part in such decision requests you have to list that property)
* the staticLearning property has been renamed ppStaticLearn to match the function name
* theory kinds files are now checked again for correctly-declared properties (this had been disabled)
* minor documentation and other fixups
|
|
* rename DeclarationScope to SymbolTable
* rename all HashStrategy -> HashFunction (which we often have anyways)
* remove CDCircList (no one is currently using it)

support yet for enumerating arrays, or for enumerating non-trivial datatypes.
|
|
Adds TheoryQuantifiers and TheoryRewriteRules, QuantifiersEngine, and other infrastructure.
Adds theory instantiators to many theories.
Adds the UF strong solver.

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.

* 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* well-foundedness / finite checks in Datatypes now superseded by type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

* 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

and not yet finalized but I need to put it in to work further with the theory writers. Please check the files that you 'own'. Any comments or discussion is welcome. Further details will be coming in a follow up email later.

get-option, get-assertions, get-value, define-sort, define-fun, and declare-sort with arity > 0; SmtEngine doesn't yet support most of these, but will shortly...

* 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.

* 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

different "kinds of kinds" (special, operator, parameterized, and constant), and permits doxygen comments on them
|
|
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).
