and model gen also.
I also expect this commit to fix bug #273.
No performance change is expected on regressions with this commit, see

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.

branch)
* add Theory::isSharedTermFact() -- it currently always returns false,
pending theory combination work
* Add "unknown" cardinalities to Cardinality class
* Fix run_regression script to handle CRLF line terminators on Macs
(where sed is non-GNU)
* Convert CRLF line terminators in datatypes regressions to LF
|

* 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.

Also, only build doxygen documentation on stuff in src/,
not test/ or contrib/ or anywhere else. Hopefully this
turns our 3000+ page user manual into something a little
more useful!

* Makes Options an "omnipresent thread-local global" (like the notion
of the "current NodeManager" was already). Options::current() accesses
this structure.
* Removes Options from constructors and data structures everywhere
(this cleans up a lot of things).
* No longer uses StatisticsRegistry statically. An instance of the
registry is created and linked to a NodeManager.
* StatisticsRegistry::current() is similar to Options::current(), but
the pointer is stowed in the NodeManager (rather than stored)
* The static functions of StatisticsRegistry have been left, for backward
compatibility; they now use the "current" statistics registry.
* SmtEngine::getStatisticsRegistry() is a public accessor for the
registry; this is needed by main() to reach in and get the registry,
for flushing statistics at the end.

(propositional) assignment for theory atoms.
Fixed Debug/Trace as discussed in bug ticket #252 and on the mailing list.
This implementation leads to some compiler warnings in production builds,
but these will be corrected in coming days. There appears to be a small
speedup in the parser as a result of this fix:
http://goedel.cims.nyu.edu/regress-results/compare_jobs.php?job_id=1902&reference_id=1886&p=5
Cleaned up a few CD Boolean attribute things.
Various small fixes to coding guidelines / test coverage.
This commit:
* Resolves bug 252 (tracing not disabled in production builds)
* Resolves bug 254 (implement CDAttrHash<>::BitIterator::find())

* Adding options --lazy-type-checking and --eager-type-checking

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

(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!)

Enabled new UF theory by default.
Added some UF regressions.
Some work on the whole equality-over-bool-removed-in-favor-of-IFF
thing. (Congruence closure module and other things have to handle
IFF as a special case of equality, etc..)
Added pre-rewriting to TheoryBool which rewrites:
* (IFF true x) => x
* (IFF false x) => (NOT x)
* (IFF x true) => x
* (IFF x false) => (NOT x)
* (IFF x x) => true
* (IFF x (NOT x)) => false
* (IFF (NOT x) x) => false
* (ITE true x y) => x
* (ITE false x y) => y
* (ITE cond x x) => x
Added post-rewriting that does all of the above, plus normalize IFF and ITE:
* (IFF x y) => (IFF y x), if y < x
* (ITE (NOT cond) x y) => (ITE cond y x)
(Note: ITEs survive the removal-of-ITEs pass only if they are Boolean-valued.)
A little more debugging output from CNF stream, context pushes/pops,
ITE removal.
Some more documentation.
Fixed some typos.

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.
