* 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.

attribute. There is now a priority queue for selecting the smallest inconsistent basic variable. normal.h has been removed. A large chunk of the registerTerm() stuff has been moved into preregister. The lazy splitting code is now been commented out so that it stops showing up in profiling.

** 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.

assignment for slack variables once solving has begun. (They cannot just be 0.) The second has to do with how assignments are backttacked. Assignments are now tracked all of the time, and are frozen once they are known to be consistent, i.e. after a successful updateInconsistentVars(). Also added a fuzz test that shows both of these problems to the regressions.

debugging statements. There is some evidence that these debugging statements were 20% of the running time for QF_LRA/miplib/fixnet-1000.smt in debug mode.
|
|
branch is a boolean should now be working. This fixes bug 138.

|
before being used. Fixed a bug in node_builder.h's crop where a pointer is dereferenced after a realloc call.
|
|
the tableau now simulates older pivots while adding a new row.
|
|
QF_LRA is now no longer complaining about seeing nodes that can be rewritten to CONST_BOOLEAN.
|
|
false. This is temporary and will be removed once TheoryEngine rewriting is more fully debugged.

debugging utility that prints out the lower bound, upper bound, assignment, and the constraints that were asserted that caused the lower bound and upperbound to be asserted.

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.

potential design for later. Resolves bug 113, invalidates bugs 93 and 94.
|
|
support has been added. Also a few bug fixes to Tableau.

rewriter.
|

Rational and Integer constructors are now explicit. This means that 'Integer = 3;' and so on are no longer permitted. This closes bug 121.
|
|
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

Real. See Bug 127 for a discussion of the hack. I am also adding a regression test that does not work (bug 128). It is not enabled so make check should still be fine.
|
|
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.

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.

This should not affect other parts of the system. This code is untested, and is volatile. It is going to be improved in the future so don't pick on it too much. I am merging this code in its current state back into the main trunk because it was getting unruly to keep merging the updated trunk back into the branch.
|
|
Also a bug fix to a couple of unit tests.
