util/options.h,cpp
|
|
* 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
|
|
notifies the theory engine through its output channel); some cleanup; add a regression for bug #216
|
|
* Add ContextMemoryAllocator<T> allocator type, conforming to
STL allocator requirements.
* Extend the CDList<> template to take an allocator (defaults
to std::allocator<T>).
* Add a specialized version of the CDList<> template (in
src/context/cdlist_context_memory.h) that allocates a list
in segments, in context memory.
* Add "forward" headers -- cdlist_forward.h, cdmap_forward.h,
and cdset_forward.h. Use these in public headers, and other
places where you don't need the full header (just the
forward-declaration). These types justify their own header
(instead of just forward-declaring yourself), because they
are complex templated types, with default template parameters,
specializations, etc.
* theory_engine.h no longer depends on individual theory headers.
(Instead it forward-declares Theory implementations.) This is
especially important now that theory .cpp files depend on
TheoryEngine (to implement Theory::getValue()). Previously,
any modification to any theory header file required *all*
theories, and the engine, to be completely rebuilt.
* Support memory cleanup for nontrivial CONSTANT kinds. This
resolves an issue with arithmetic where memory leaked for
each distinct Rational or Integer that was wrapped in a Node.

supported; work on Result type (biggest noticeable change is that CVC4 now outputs lowercase "sat" and "unsat"), Options class moved to src/smt, to allow for future work on runtime configuration via (set-option) command
|
|
(get-value ...) SMT-LIBv2 command. As per SMT-LIBv2 spec,
you must pass --interactive --produce-models on the command
line (although they don't currently make us do any extra
work). Closes bug #213.

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.

calling them directly. In tests this doesn't appear to
lead to slowdown.

bool); also make theoryOf(= t1 t2) return theoryOf(t1.getType()), rather than theoryOf(t1), as the latter gives different results for (= (geq x1 x2) (leq x2 x1)) and (= a (leq x2 x1)), which is strange and causes problems. should discuss at tuesday meeting. resolves bug 187.

post-rewrite, another full rewrite is performed and the results
compared).
Also added another response code to rewriters. Theories return a
CVC4::theory::RewriteResponse from preRewrite() and postRewrite().
This class has nice subclasses to make the theory rewriters somewhat
self-documenting in termination behavior. They look like
tail-recursive rewriting calls, but they're not; they are
instantiations of the RewriteResponse result code, which carries the
Node being returned:
// Flags the node as DONE pre- or post-rewriting, though this is
// ignored if n belongs to another theory.
//
// NOTE this just changed name from RewritingComplete(), which
// didn't match RewriteAgain().
//
return RewriteComplete(n);
// Flags the node as needing another pre-rewrite (if returned from a
// preRewrite()) or post-rewrite (if returned from a postRewrite()).
//
return RewriteAgain(n);
// Flags the node as needing another FULL rewrite. This is the same
// as RewriteAgain() if returned from preRewrite(). If it's returned
// from postRewrite(), however, this causes a full preRewrite() and
// postRewrite() of the Node and all its children (though the cache is
// still in effect, which might elide some rewriting calls).
//
// This would have been another fix for bug #168. Its use should be
// discouraged in practice, but there are places where it will
// probably be necessary, where a theory rewrites a Node into
// something in another theory about which it knows nothing.
// A common case is where the returned Node is expressed as a
// conjuction or disjunction of EQUALs, or a negation of EQUAL,
// where the EQUAL is across terms in another theory, and that EQUAL
// subterm should be seen by the owning theory.
//
return FullRewriteNeeded(n);

* 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
|
|
* 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.

expect a little turbulence. This commit will not compile. There will be a second commit that fixes this in a moment. I am delaying a change to avoid svn whining about a conflict.

** 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.

for it as well. make check should now work again.

to its final destination. Added a basic rewriter to TheoryUF. (x=x rewrites to true.) Added DIVISION to src/expr/node_manager.cpp's getType. Fixed the theory returned for variables in theoryOf() for bool and arith. Fixed TheoryEngine rewrite children to properly handle APPLY_UFs. Removed the special case for equality in TheoryEngine rewrite. A few tests are currently broken due to deallocation errors. Morgan and I will try to commit a fix to this in a little bit.
|
|
support has been added. Also a few bug fixes to Tableau.
|
|
To be done:
* Add erasable map Clause* to bool to minisat (backtracks with the solver)
* Add map from Clause* to Node (clauses that came from a node)
* Add reference counting Literal -> Node to CNFManager
* If Literal -> Node refcount goes to zero, the clauses of Node can be erased (if eresable)
* If clause is erased for each L in clause L -> Node refcount goes down
|
|
TheoryArith. Also directly hacked in support for theoryOf() to work for equalities where the left hand is a variable of type real.
|
|
fixes and organizational changes. The theory is now enabled to perform checking in the TheoryEngine. This draft can now solve 2 new regression tests test/regress/regress0/ineq_slack.smt and test/regress/regress0/ineq_basic.smt. There is also a small bug fix inside src/expr/attribute.h.
|
|
* 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.

comments to files without them

* Other minor changes to the new parser to match coding guidelines,
add documentation, ....
* Add CFLAGS stuff to configure.ac parser Makefile.ams. This ensures
that profiling, coverage, optimization, debugging, and warning
level options will apply to the new parser as well (which is in C,
not C++). This fixes the deprecated warning we were seeing this
evening.
* Now, if you have ANTLR_HOME set in your environment, you don't need
to specify --with-antlr-dir to ./configure or have libantlr3c
installed in standard places. --with-antlr-dir still overrides
$ANTLR_HOME, and if the installation in $ANTLR_HOME is missing or
doesn't work, the standard places are still tried.
* Extend "silent make" to new parser stuff.
* Added src/parser/bounded_token_buffer.{h,cpp} to the list of
exclusions in contrib/update-copyright.pl and mention them as
excluded from CVC4 copyright in COPYING. They are antlr3-derived
works, covered under a BSD license.
OTHER STUFF:
* expr_manager.h, expr.h, expr_manager.cpp, and expr.cpp are now
auto-generated by a "mkexpr" script. This provides the correct
instantiations of mkConst() for public use, e.g., by the parser.
* Fix doxygen documentation in expr, expr_manager.. closes bug #35
* Node::isAtomic() implemented in a better way, based on theory kinds
files. Fixes bug #40. To support this, a "nonatomic_operator"
command has been added. All other "parameterized" or "operator"
kinds are atomic.
* Added expr_black test
* Remove kind::TRUE and kind::FALSE and make a new CONST_BOOLEAN kind
that takes a "bool" payload; for example, to make "true" you now do
nodeManager->mkConst(true).
* Make new "cvc4_public.h" and "cvc4parser_public.h" headers. Private
headers should include "cvc4_private.h"
(resp. "cvc4parser_private.h"), which existed previously. Public
headers should include the others. **No one** should include the
autoheader #include (which has been renamed "cvc4autoconfig.h")
directly, and public CVC4 headers can't access its #defines. This
is to avoid us having the same distribution problem as libantlr3c.
* Preliminary fixes based on Tim's code review of attributes (bug #61).
This includes splitting hairy template internals into
attribute_internals.h, for which another code review ticket will be
opened. Bug is still outstanding, but pending further
refactoring/documentation.
* Some *HashFcns renamed to *HashStrategy to match refactoring done
elsewhere (done by Chris?) earlier this week.
* Simplified creation of make rules for generated files (expr.cpp,
expr.h, expr_manager.cpp, expr_manager.h, theoryof_table.h, kind.h,
metakind.h).
* CVC4::Configuration interface and implementation split (so private
stuff doesn't leak into public headers).
* Some documentation/code formatting fixes.
* Add required versions of autotools to autogen.sh.
* src/expr/mkmetakind: fix a nonportable thing in invocation of "expr"
that was causing warnings on Red Hat.
* src/context/cdmap.h: add workaround to what appears to be a g++ 4.1
parsing bug.
|
|
* 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
|
|
* CVC4::theory::Interrupted no longer derives CVC4::Exception.
* Interrupted is only thrown if "safe" parameter is TRUE !
* UF returns one conflict (instead of waiting for Interrupted to be thrown).
* Minor build system work (quieter builds if V=0, better handling of build
profiles in configure)
|
|
clauses and:
* adding the smallest test case (eq_diamond23.smt) that memouts in 50s
* adding the initial attributes black box test
|
|
DecisionEngine, and Theory. These are triggered from the SmtEngine
dtor before the other engines are deleted. This is important
because of potential issues with outstanding TNodes in Theory
implementations (which fail if the destruction is done in the wrong
order, in certain cases).
* Favor "FactQueueResetter" instead of clearAssertionQueues() for
resetting facts queue in Theory implementations.
* Better theory-rewriting code.
* Minor cleanups.
|

the theories didn't get cleared on SatSolver backtracking so there were unasserted literals being returned as part of some conflicts. Sat solver now explicitely calls in the theory engine after it backtracks in order to clear the queues (clearAssertionQueues).
Also, changed the let.smt as it used to exibit "single literal conflict" problem. The sat solve can not except conflicts similar to (x != x), these should be rewritten to false during pre-processing.
Adding 3 more small problems from the library that we can solve now to the regressions.

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).
|
|
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).
