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.

* Preprocessing-time, non-clausal, Boolean simplification round to
support "quasi-non-linear rewrites" as discussed at last few meetings.
* --simplification=none is the default for now, but we'll probably
change that to --simplification=incremental. --simplification=batch
is also a possibility. See --simplification=help for details.
* RecursionBreaker<T> now uses a hash set for the seen trail.
* Fixes to TLS stuff to support that.
* Fixes to theory and SmtEngine documentation.
* Fixes to stream indentation.
* Other miscellaneous stuff.

constructors for Type and Expr (which existed due to ANTLR limitations). These issues are now handled (as a hack, due to said limitations) in the parser rather than the CVC4 core.

* 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

Expected performance impact outside of datatypes/CVC parser is
negligible.
* CVC language LAMBDA, functional LET, type LET, precedence fixes,
bitvectors, and arrays, with partial parsing support also for
quantifiers, tuples, subranges, subtypes, and records
* support for complex recursive DATATYPE selectors, e.g.
tree = node(children:ARRAY INT OF tree) | leaf(data:INT)
these are complicated because they have to be left unresolved
at parse time and dealt with in a second pass.
* bugfix for Exprs/Types that occurred when setting them to null
(not Nodes/TypeNodes, just Exprs/Types).
* Cleanup/code review items

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.

are somewhat disparate but belonged on the same branch because they were
held back from trunk all for the same reason (to keep the trunk stable
for furious bitvector development). Dejan has now given me the go-ahead
for a merge.
=========================================
THIS COMMIT CHANGES THE THEORY INTERFACE!
=========================================
Theory constructors are expected to take an additional "Valuation*"
parameter that each Theory should send along to the base class
constructor. The base class Theory keeps the Valuation* in a
d_valuation field for use by it and by its derived classes.
Theory::getValue() no longer takes a Valuation* (it is expected
to use d_valuation instead). This allows other theory functions
to take advantage of getValue() for debugging or heuristic
purposes.
TODO BEFORE MERGE TO TRUNK:
****implement BitIterator find() in CDAttrHash<bool>.
Specifically:
* Added QF_BV support for SMT-LIB v2.
* Two adjustments to the theory interface as requested by Tim King:
1. As described above.
2. Theories now have const access to the fact queue through base
class functions facts_begin() and facts_end(); useful for
debugging.
* Added an "Asserted" attribute so that theories can check if something
has been asserted or not (and therefore not propagate it). However, this
has been disabled for now, pending more data on the overhead of it, and
pending discussion at the 3/25/2011 meeting.
* Do not define NDEBUG in MiniSat in assertion-enabled builds (so
that MiniSat asserts are evaluated).
* As a result of the new MiniSat assertions, some --incremental
regressions had to be disabled; also, some bitvectors ?!!
* Bug 71 is resolved by adding a specialization for CDAttrHash<> in the
attribute package.
* Fixes for some warnings flagged by clang.
* System tests have arrived! So far mainly infrastructure for having
system tests, but there is a system test aimed at improving code
coverage of the printer package.
* Minor other adjustments to documentation and coding to be more
conformant to CVC4 policy.
Tests have been performed to demonstrate that these changes have no or
negligible effect on performance. In particular, changing the
CDAttrHash<> doesn't have any real effect on performance or memory right
now, since there is only one context-dependent boolean flag (as soon
as another is added, the effect is noticeable but probably still slight).

the language: LET now supported (but not "type-lets" yet), OPTION now supported, and ^ operator (exponentiation) supported for nonnegative integer exponents. The latter simply expands to MULT, and of course fails assertions in arithmetic if a variable is raised to n >= 2. Also other CVC parser clean-up.

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.

* 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.

(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!)
