This commit adds a statistic that records the total size of all proofs
generated by an instance of `SmtEngine`. The commit also moves
`SmtEngine::checkProof()` into `smt_engine.cpp` because it needs to know
the complete type of `d_stats` (and the separate file for that method
didn't seem that useful). Additionally, it changes
`smt::SmtEngine::checkProofTime` to `smt::SmtEngine::lfscCheckProofTime`
that only measures the time spent in LFSC and adds a statistic
`proof::ProofManager::proofProductionTime` that measures the proof
production time separately (also works with `get-proof`/`--dump-proof`).

* Split BitvectorProof into a sub/superclass
The superclass contains general printing knowledge.
The subclass contains CNF or Resolution-specific knowledge.
* Renames & code moves
* Nits cleaned in prep for PR
* Moved CNF-proof from ResolutionBitVectorProof to BitVectorProof
Since DRAT BV proofs will also contain a CNF-proof, the CNF proof should
be stored in `BitVectorProof`.
* Unique pointers, comments, and code movement.
Adjusted the distribution of code between BVP and RBVP.
Notably, put the CNF proof in BVP because it isn't
resolution-specific.
Added comments to the headers of both files -- mostly BVP.
Changed two owned pointers into unique_ptr.
BVP's pointer to a CNF proof
RBVP's pointer to a resolution proof
BVP: `BitVectorProof`
RBVP: `ResolutionBitVectorProof`
* clang-format
* Undo manual copyright modification
* s/superclass/base class/

* make LFSCBitVectorProof::printOwnedSort public
* Andres's Comments
Mostly cleaning up (or trying to clean up) includes.
* Cleaned up one header cycle
However, this only allowed me to move the forward-decl, not eliminate
it, because there were actually two underlying include cycles that the
forward-decl solved.
* Added single _s to header gaurds
* Fix Class name in debug output

* Reordered methods in BitVectorProof per original ordering

Currently, we have an LFSCSatProof which inherits from TSatProof and
implements printing the proof. The seperation is not clean (e.g.
clauseName is used for printing only but is in TSatProof) and the
inheritance does not add any value while making dependencies more
confusing. The plan is that TSatProof becomes a self-contained part that
the MiniSat implementations generate and ProofManager prints out. This
commit is a first step in that direction. For SAT solvers with native
capabilities for producing proofs, we would simply implement a different
LFSC printer of their proof representation without changing the SAT
solver itself. The inheritance would make this awkward to deal with.
Additionally, the commit cleans up some unused functions and adjusts the
visibility of TSatProof methods and members.

This commit adds support for the --fewer-preprocessing-holes flag. This
flag changes the preprocessing part in proofs in two ways: it (1)
removes assertions that are just restating inputs and uses the inputs
directly instead and it (2) changes the form of the preprocessed
assertions to contain the input that they originate from.
The code in this commit is mostly taken from the proofs branch in Guy's
fork.

core. Currently, lemmas that are not conjunctions and their own weakest implicants; but for lemmas that *are* conjunctions, we may return only a subset of the conjuncts.
|
|
|
|
participate in the unsat cores.
Currently this is only limited to lemmas generated via the d_out->lemma() interface, i.e. no propagations
and conflict lemmas.

Added a flag to enable/disbale this feature (enabled by default).
Also, added some infrastructure for proving rewrite rules.

- Options
-- Added the new option attribute :notify. One can get a notify() call on the Listener after a the option's value is updated. This is the new preferred way to achieve dynamic dispatch for options.
-- Removed SmtOptionsHandler and pushed its functionality into OptionsHandler and Listeners.
-- Added functions to Options for registering listeners of the notify calls.
-- Changed a number of options to use the new listener infrastructure.
-- Fixed a number of warnings in options.
-- Added the ArgumentExtender class to better capture how arguments are inserted while parsing options and ease memory management. Previously this was the "preemptGetopt" procedure.
-- Moved options/options_handler_interface.{cpp,h} to options/options_handler.{cpp,h}.
- Theories
-- Reimplemented alternative theories to use a datastructure stored on TheoryEngine instead of on Options.
- Ostream Handling:
-- Added new functionality that generalized how ostreams are opened, options/open_stream.h.
-- Simplified the memory management for different ostreams, smt/managed_ostreams.h.
-- Had the SmtEnginePrivate manage the memory for the ostreams set by options.
-- Simplified how the setting of ostreams are updated, smt/update_ostream.h.
- Configuration and Tags:
-- Configuration can now be used during predicates and handlers for options.
-- Moved configuration.{cpp,h,i} and configuration_private.h from util/ into base/.
-- Moved {Debug,Trace}_tags.* from being generated in options/ into base/.
- cvc4_private.h
-- Upgraded #warning's in cvc4_private.h and cvc4_private_library.h to #error's.
-- Added public first-order (non-templatized) member functions for options get and set the value of options outside of libcvc4. Fixed all of the use locations.
-- Made lib/lib/clock_gettime.h a cvc4_private_library.h header.
- Antlr
-- Fixed antlr and cvc4 macro definition conflicts that caused warnings.
- SmtGlobals
-- Refactored replayStream and replayLog out of SmtGlobals.
-- Renamed SmtGlobals to LemmaChannels and moved the implementation into smt_util/lemma_channels.{h,cpp}.

- Splitting the two instances of CheckArgument. The template version is now always defined in base/exception.h and is available in a cvc4_public header. This version has lost its variadic version (due to swig not supporting va_list's). The CPP macro version has been renamed PrettyCheckArgument. (Taking suggestions for a better name.) This is now only defined in base/cvc4_assert.h. Only use this in cvc4_private headers and in .cpp files that can use cvc4_private headers. To use a variadic version of CheckArguments, outside of this scope, you need to duplicate this macro locally. See cvc3_compat.cpp for an example.
- Making fitsSignedInt() and fitsUnsignedInt() work more robustly for CLN on 32 bit systems.
- Refactoring ArrayStoreAll to avoid potential problems with circular header inclusions.
- Changing some headers to use iosfwd when possible.

This avoids conflicts when CVC4 is linked to an application that

generation; fix bug 285.
* segfaults/assert-fails in proof-generation fixed, including bug 285
* added --check-proofs to automatically check proofs, like --check-models (but only for UF/SAT at present)
* proof generation now works in portfolio (but *not* --check-proofs, since LFSC code uses globals)
* proofs are *not* yet supported in incremental mode
* added --dump-proofs to dump out proofs, like --dump-models
* run_regression script now runs with --check-proofs where appropriate
* options scripts now support :link-smt for SMT options, like :link for command-line

just the header comments at the top, though. Don't update to this rev if
you don't have time for a complete rebuild, and exclude this rev if you
want to see what's new across a range of commits.

- 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.
