minor fix-ups to documentation and some node stuff

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())

(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.

resolves bug 175. also newer URL for config/pkg.m4

building with CLN or with GMP, the contrib/switch-config script
(enabling "fast switching" of different configurations in the same
builds/ directory), and also some minor changes.
./configure --with-gmp (or --without-cln) forces building with GMP
and doesn't even look for CLN. Configure fails if GMP isn't installed.
./configure --with-cln (or --without-gmp) forces building with CLN
and doesn't even look for GMP. Configure fails if CLN isn't installed.
./configure [no arguments] will detect what's installed. CLN is
default, if it isn't installed, or is too old, GMP is looked for (and
configure fails if neither is available).
It is an error to specify --with-gmp --with-cln (or --without-* for
both) at the same time.
Building with CLN (whether forced or detected) adds a note to the
configure output mentioning the fact that the build of CVC4 will be
linked against a GPLed library and notifying the user of the
--without-cln option.
Building with GMP (whether forced or detected) affects the build
directory, so CLN and GMP builds are kept separate.
./configure --with-cln debug builds in builds/$arch/debug
./configure --with-gmp debug builds in builds/$arch/debug-gmp
The final binaries are linked explicitly against either gmp or cln,
but not both. If linked against cln, cln pulls in gmp as a
dependency, so the result will be linked against both.
=== Details that you probably don't care about ===
The headers src/util/{integer,rational}.h are generated from the
corresponding .in versions. A user installing a CVC4-devel package
will get the headers for rational and integer that match the library
that s/he installs.
The preprocessor #defines CVC4_GMP_IMP and CVC4_CLN_IMP are added to
cvc4autoconfig.h. Only one is ever #defined. cvc4autoconfig.h
doesn't need to be #included directly; you get it through #including
cvc4_private.h (or the parser version).
AM_CONDITIONALs are also defined so that Makefiles get the cln/gmp
configuration. AC_SUBSTs are defined so that public headers (see
src/util/{integer,rational}.h.in) can use the setting.
*Public* headers that need to depend on the cln/gmp configuration
can't use cvc4autoconfig.h, because we're keeping that in the private,
internal-only space, never to be installed on users' machines. Here,
something special is required, like the configure-level generation of
headers that I used for src/util/{integer,rational}.h.in.
Tim's Integer and Rational wrappers are the only bits of code that
should care which library is used (and also src/util/configuration.h,
which gives the user of the library information about how CVC4 is
built), and possibly some unit tests (?).
