Dump("foo") << FooCommand(...);
now "dumps" the textual representation of the command (in the current
output language) to a file, IF dumping is on at configure-time, AND the
"muzzle" feature is off, AND the "foo" flag is turned on for the dump
stream during this run.
If it's a portfolio build, the above will also store the command in a
CommandSequence, IF the "foo" flag is turned on for the dump stream
during this run. This is done even if the muzzle is on.
This commit also cleans up some code that used the dump feature (in arrays,
particularly).

support incrementality.
Some clean-up work will likely follow, but the CNF/Minisat stuff should be
left pretty much untouched.
Expected performance change negligible; slightly better on memory:

Note that there are crashes, but that these are exhibited in the nightly
regression run too!

SMT-LIBv1 and SMT-LIBv2 input:
In SMT-LIBv1, you specify the "cvc4_logic" benchmark attribute; for instance:
(benchmark actually_a_sat_benchmark_but_looks_like_uf
:logic QF_UF
:cvc4_logic { QF_SAT }
[...]
In SMT-LIBv2, you use a set-info; for instance:
(set-logic QF_UF)
(set-info :cvc4-logic "QF_SAT")
[...]
Right now, the only thing this does is disable the symmetry breaker for
benchmarks like the above ones.
As part of this work, TheoryEngine::setLogic() was removed (the logic field there
wasn't actually used anywhere, its need disappeared when
Theory::setUninterpretedSortOwner() was provided).
Also, Theory::d_uninterpretedSortOwner got a name change to
Theory::s_uninterpretedSortOwner, to highlight that it is static to the Theory
class. This represents a breakage of our separation goals for CVC4, since it
means that two SmtEngines cannot be created separately to solve a QF_AX and
QF_UF problem. A bug report is pending.

and SMT-LIBv2).
There are --enable-symmetry-breaker and --disable-symmetry-breaker
options that are always respected regardless of this default.
Expected performance impact: positive
New default (UF only) compared to old default (always on):

Symmetry breaker remains a big win on UF:
http://church.cims.nyu.edu/regress-results/compare_jobs.php?job_id=3594&reference_id=3596&p=5
The last link to results looks at first that the symmetry breaker should
always be turned off, since its use loses more regressions than it gains.
*However*, the lost ones are only our "QF_SAT" benchmarks. For these, we
should indeed turn off the symmetry breaker, but that's impossible for
now because we tag them internally with the logic "QF_UF."

allows a (limited) form of error recovery, matching what we had previously

exceptions are not thrown outside the library. Reflect this in the exit code of the driver. Fixes a bug found by Tim among the nightly regressions.
Also improved error reporting if antlr is unavailable and the parsers need to be generated.

* with a patched SWIG, the ocaml bindings build correctly.
** I will provide my patch to the SWIG dev team.
* fixed some class interfaces to play more nicely with SWIG.
* php, perl, tcl now work; examples added.
* improved binding module building and installation.
Also:
Stop #defining NULL ((void*) 0). This has been in cvc4_public.h for
a long, long time, I forget why I added it in the first place, and
it's a very, very bad idea. In C++, certain things are permitted
for NULL that aren't permitted for ((void*) 0), like for instance
implicit conversion to any pointer type. We didn't see an issue
here (until now, when interfacing with SWIG), because GCC is usually
pretty smart at working around such a broken #definition of NULL.
But that's fragile.
New exception-free Command architecture. Previously, some command
invocations were wrapped in a try {} catch() {} and printed out an
error. This is much more consistent now. Each Command invocation
results in a CommandStatus. The status can be "unsupported",
"error", or "success" (these are each derived classes, though, not
strings, so that they can be easily printed in a language-specific
way... e.g., in SMT-LIBv2, they are printed in a manner consistent
with the spec, and "success" is not printed if the print-success
option is off.) All Command functionality are now no-throw
functions, which @cconway reports is a Good Thing for Google
(where all C++ exceptions are suspect), and also I think is much
cleaner than the old way in this instance.
Added an --smtlib2 option that enables an "SMT-LIBv2 compliance
mode"---really it just sets a few other options like strictParsing,
inputLanguage, and printSuccess. In the future we might put other
options into a compliance mode, or we might choose to make it the
default.

still write, for example:
#include "expr/node.h"
but public CVC4 headers, upon installation to /usr/include/cvc4 (or wherever),
have such #includes rewritten automatically to:
#include <cvc4/expr/node.h>
|
|
Nodes---useful for debugging.
* language-dependent Node::toString()
* some minor proof-related cleanup

- can now output LFSC checkable resolution proofs
- added configuration option --enable-proof
- added command line argument --proof
To turn proofs on build with proofs enabled and run with --proof.

I also expect this commit to fix bug #273.

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.

* add Theory::isSharedTermFact() -- it currently always returns false,
pending theory combination work
* Add "unknown" cardinalities to Cardinality class

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.

* Fixes to TLS stuff to support that.
* Fixes to theory and SmtEngine documentation.

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())
