* separated SatSolverInput interface class into two classes:
- TheoryProxy for the sat solver to communicate with the theories
- SatSolverInterface abstract class to communicate with the sat solver
* instead of using #ifdef typedef for SatClauses and SatLiterals, now there are CVC4 SatLiteral/SatClause types and mappings between them and the internal sat solver clause/literal representation
* added abstract classes for DPLLSatSolver and BVSatSolver different interfaces
Replaced TheoryBV with bitblasting implementation:
* all operators bitblasted
* only operator elimination rewrite rules so far

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.

* 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>

SmtEngine::getProof(), a few other things..
|
|
Nodes---useful for debugging.
* language-dependent Node::toString()
* some minor proof-related cleanup

Details here: http://goedel.cims.nyu.edu/wiki/Meeting_Minutes_-_October_14,_2011#Resource.2Ftime_limiting_API
This will need more work, but it's a start.
Also implemented TheoryEngine::properPropagation().
Other minor things.

auto-detection of libantlr3c, I chose an innocent-looking function that was present in both versions. But it's signature had changed, breaking source compatibility in both directions. Just like the other function that started the whole mess. Silly me.

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.

minor fix-ups to documentation and some node stuff
|

* compilation fixes for GCC 4.6.x
+ ptrdiff_t is now in std::
* fix some make rules that are ok in Make 3.81 but broke in Make 3.82
* look for cxxtestgen.py as well as cxxtestgen.pl, and look for cxxtest headers in /usr/include

on some problems---valgrind gave many complaints): the problem was that calloc() (in the Backtracker) wasn't allocating enough space for the type located at the resulting address. Resolves bug #263.
Also, some debugging improvements.

datatypes review

review of Andy's earlier commit, with some minor code clean-up and documentation
|

parametric datatypes, type ascriptions are not implemented yet

* 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.
