Towards disentangling Options / NodeManager / SmtEngine.
This PR removes options --use-theory=NAME and --replay/--replay-log. Both of these options are highly complex, unused, and lead to complications when implementing the way options and our build system work.
The first is motivated by making TheoryEngine use an "alternate" theory, which appears to e.g. make it so that TheoryIdl could entirely replace TheoryArith. I believe this is too heavy handed of a solution: there should a consistent TheoryArith class, and options should be used to enable/disable alternate modules within it.
The second attempts to replay low level decisions from the SAT solver. It is documented as not working (in 1.0). I do not believe this is worth salvaging.
It also removes the solver in src/theory/idl, which cannot be enabled after this commit.

Previously, the metakind header defined macros for the number of bits
reserved for fields in the NodeValue "header" (for the reference count,
the node kind, the number of children and the node id). These macros
were redundant, since the only one using them was the NodeValue itself,
which redefined them (while using them) as constants in the class.
Additionally, MAX_CHILDREN was defined (using these macros) not only
in the metakind header, but redefined in other places.
This commit defines the above values as constexpr members of the
NodeValue class and cleans up redundancy.

* This is a feature that Dejan and I want for the upcoming tutorial.
It allows rapid prototyping of new decision procedure implementations
(which we may choose to demonstrate), and a new --use-theory command-line
option to select from different available implementations. It has no
affect on the current set of theories, as no "alternates" are defined.
* Also update the new-theory script, which was broken and incomplete.

* update some copyrights for 2013
* cleaned up some comments/ifdefs, indentation

(this commit was certified error- and warning-free by the test-and-commit script.)
|

* --early-exit and --no-early-exit command line options (the former is default for all builds except debug builds)
* New SEXPR kind for doing lists of things (we previously used TUPLEs for this purpose, but TUPLEs will be used in future by the datatypes theory, and so cannot have function symbols in them, etc.).
* SMT-LIB compliant output for (set-option :produce-unsat-cores true) and (get-unsat-core)
(this commit was certified error- and warning-free by the test-and-commit script.)

* rename DeclarationScope to SymbolTable
* rename all HashStrategy -> HashFunction (which we often have anyways)
* remove CDCircList (no one is currently using it)

isConst() and isVar() as appropriate)
also some base infrastructure for the new ::isConst().

support yet for enumerating arrays, or for enumerating non-trivial datatypes.
|
|
Adds TheoryQuantifiers and TheoryRewriteRules, QuantifiersEngine, and other infrastructure.
Adds theory instantiators to many theories.
Adds the UF strong solver.

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.

* new "well-foundedness" type property (like cardinality) specified in
Theory kinds files; specifies well-foundedness and a ground term
* well-foundedness / finite checks in Datatypes now superseded by type
system isFinite(), isWellFounded(), mkGroundTerm().
* new "RecursionBreaker" template class, a convenient class that keeps
a "seen" trail without you having to pass it around (which is
difficult in cases of mutual recursion) of the idea of passing
around a "seen" trail
|
|
* 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

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!)

* added TheoryArith::preRewrite() to test and demonstrate
the use of pre-rewriting.
* array types and type checking now supported
* array type checking now supported
* theoryOf() dispatching properly to arrays now
* theories now required to implement a (simple) identify()
function that returns a string identifying them for
debugging/user output purposes
* added "builtin" theory to hold all built-in kinds and their
type rules and rewriting (currently only exploding distinct)
* fixed production build failure (regarding NodeSetDepth)
* removed an errant "using namespace std" in util/bitvector.h
(and made associated trivial fixes elsewhere)
* fixes to make unexpected exceptions more verbose in debug builds
* fixes to make multiple, cascading assertion fails simpler
* minor other fixes to comments etc.

potential design for later. Resolves bug 113, invalidates bugs 93 and 94.

instead of the kind, i.e.
Expr op = ..."f"...
em.mkExpr(op, children);
Operator kinds are automatically associated with the enclosing expression kind in the DSL and generated.
|
|
auto-generated headers (metakind.h etc.), so they don't have to be
recompiled every time. This drastically improves build time when
only small updates are made.
* Added "memory.h" unit test header for checking out-of-memory
conditions. cdlist_black uses it.
* Added helpful output when you "make lcov" in a non-coverage-enabled
build.
* Removed strict aliasing warning when compiling metakind.h header
with optimization on.
* Removed const version of NodeBuilder::operator Node()---it was
poorly performing, better to not permit it---and fixed the
convenience builders to use the non-const version
(re: code review #63)
* Color-coded test output on capable terminals.
* Fixed some warnings in unit tests.

instead of assuming it's atomic based on kind. Atomicity is
determined at node building time. Fixes bug #81. If this is
determined to make node building too slow, we can allocate another
attribute "AtomicHasBeenComputed" to lazily compute atomicity.
* TheoryImpl<> has gone away. Theory implementations now derive from
Theory directly and share a single RegisteredAttr attribute for term
registration (which shouldn't overlap: every term is "owned" by
exactly one Theory). Fixes bug #79.
* Additional atomicity tests in ExprBlack unit test.
* More appropriate whitebox testing for attribute ID assignment
(AttributeWhite unit test).
* Better (and more correct) assertion checking in NodeBuilderBlack.
* run-regression script now checks exit status against what's provided
in "% EXIT: " gesture in .cvc input files, and stderr against
"% EXPECT-ERROR: ". These can be used to support intended failures.
Fixes bug #84. Also add "% EXIT: " gestures to all .cvc regressions
in repository.
* Solved some "control reaches end of non-void function" warnings in
src/parser/bounded_token_buffer.cpp by replacing
"AlwaysAssert(false)" with "Unreachable()" (which is known
statically to never return normally).
* Regression tests now use the cvc4 binary under
builds/$(CURRENT_BUILD)/src/main instead of the one in bin/ which
may not be properly installed yet at that point of the build.
(Partially fixes bug #46.)
* -fvisibility=hidden is now included by configure.ac instead of each
Makefile.am, which will make it easier to support platforms
(e.g. cygwin) that do things a different way.
* TheoryUF code formatting. (re: my code review bug #64)
* CDMap<> is leaking memory again, pending a fix for bug #85 in the
context subsystem. (To avoid serious errors, can't free context
objects.)
* add ContextWhite unit test for bug #85 (though it's currently
"defanged," awaiting the bugfix)
* Minor documentation, other cleanup.
|
|
* Other minor changes to the new parser to match coding guidelines,
add documentation, ....
* Add CFLAGS stuff to configure.ac parser Makefile.ams. This ensures
that profiling, coverage, optimization, debugging, and warning
level options will apply to the new parser as well (which is in C,
not C++). This fixes the deprecated warning we were seeing this
evening.
* Now, if you have ANTLR_HOME set in your environment, you don't need
to specify --with-antlr-dir to ./configure or have libantlr3c
installed in standard places. --with-antlr-dir still overrides
$ANTLR_HOME, and if the installation in $ANTLR_HOME is missing or
doesn't work, the standard places are still tried.
* Extend "silent make" to new parser stuff.
* Added src/parser/bounded_token_buffer.{h,cpp} to the list of
exclusions in contrib/update-copyright.pl and mention them as
excluded from CVC4 copyright in COPYING. They are antlr3-derived
works, covered under a BSD license.
OTHER STUFF:
* expr_manager.h, expr.h, expr_manager.cpp, and expr.cpp are now
auto-generated by a "mkexpr" script. This provides the correct
instantiations of mkConst() for public use, e.g., by the parser.
* Fix doxygen documentation in expr, expr_manager.. closes bug #35
* Node::isAtomic() implemented in a better way, based on theory kinds
files. Fixes bug #40. To support this, a "nonatomic_operator"
command has been added. All other "parameterized" or "operator"
kinds are atomic.
* Added expr_black test
* Remove kind::TRUE and kind::FALSE and make a new CONST_BOOLEAN kind
that takes a "bool" payload; for example, to make "true" you now do
nodeManager->mkConst(true).
* Make new "cvc4_public.h" and "cvc4parser_public.h" headers. Private
headers should include "cvc4_private.h"
(resp. "cvc4parser_private.h"), which existed previously. Public
headers should include the others. **No one** should include the
autoheader #include (which has been renamed "cvc4autoconfig.h")
directly, and public CVC4 headers can't access its #defines. This
is to avoid us having the same distribution problem as libantlr3c.
* Preliminary fixes based on Tim's code review of attributes (bug #61).
This includes splitting hairy template internals into
attribute_internals.h, for which another code review ticket will be
opened. Bug is still outstanding, but pending further
refactoring/documentation.
* Some *HashFcns renamed to *HashStrategy to match refactoring done
elsewhere (done by Chris?) earlier this week.
* Simplified creation of make rules for generated files (expr.cpp,
expr.h, expr_manager.cpp, expr_manager.h, theoryof_table.h, kind.h,
metakind.h).
* CVC4::Configuration interface and implementation split (so private
stuff doesn't leak into public headers).
* Some documentation/code formatting fixes.
* Add required versions of autotools to autogen.sh.
* src/expr/mkmetakind: fix a nonportable thing in invocation of "expr"
that was causing warnings on Red Hat.
* src/context/cdmap.h: add workaround to what appears to be a g++ 4.1
parsing bug.

* add NodeManagerWhite unit test
* change kind::APPLY to kind::APPLY_UF
* better APPLY handling: operators are no longer considered children
* more efficient pool lookup; the NodeValue doesn't have to be as fully constructed for the lookup to proceed
* extend DSL for kind declarations
+ new "theory" command declares a theory and its header. theory_def.h no longer required.
+ arity enforced on operators
+ constant mapping, hashing, equality
* CONSTANT metakinds supported (via Node::getConst<T>(), for example, Node::getConst<CVC4::Rational>() gets a Rational out of a Node (assuming it is of CONST_RATIONAL kind)
* added CONST_RATIONAL and CONST_INTEGER kinds
* builtin operators (AND, OR, PLUS, etc..) returned by Node::getOperator() are now CONSTANT metakind and are created by NodeManager
* Pretty-printing of Nodes now has a depth limit settable by a stream manipulator (e.g. "cout << Node::setdepth(5) << m << endl;" prints DAG rooted at m to a depth of 5)
* getters added to Node, TNode, NodeValue, etc., for operators and metakinds
* build-time generators for kind.h, metakind.h, and theoryof_table.h headers now have a simpler design and flag errors better, and the templates (kind_template.h etc.) are easier to understand.
* DISTINCT is now a kind, and the SMT parser now passes through DISTINCT nodes instead of blowing them up into ANDs. Until theory rewriting is online, though, DISTINCTs are directly blown up into conjunctions in TheoryEngine::rewrite().
* add gmpxx detection and inclusion
* better Asserts throughout, some documentation, cleanup
