Refactored CnfStream to work with the bv theory Bitblaster:
    * 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

12 years agoAdded ability to set a "cvc4-specific logic" in standards-compliant
Morgan Deters [Thu, 23 Feb 2012 23:08:03 +0000 (23:08 +0000)]
Added ability to set a "cvc4-specific logic" in standards-compliant
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.

Added OutputChannel::propagateAsDecision() functionality, allowing a theory
to request a decision on a literal.  All these theory requests are kept in a
context-dependent queue and serviced in order when the SAT solver goes to make a
decision.  Requests that don't have a SAT literal give an assert-fail.  Requests
for literals that already have an assignment are silently ignored.

Since the queue is CD, requests can actually be serviced more than once (e.g., if
a request is made at DL 5, but not serviced until DL 10, and later, a conflict
backtracks to level 7, the request may be serviced again).
