Substantial Changes:
-ITE Simplification
-- Moved the utilities in src/theory/ite_simplifier.{h,cpp} to ite_utilities.
-- Separated simpWithCare from simpITE.
-- Disabled ite simplification on repeat simplification by default. Currently, ite simplification cannot help unless we internally make new constant leaf ites equal to constants.
-- simplifyWithCare() is now only run on QF_AUFBV by default. Speeds up nec benchmarks dramatically.
-- Added a new compress ites pass that is only run on QF_LIA by default. This targets the perverse structure of ites generated during ite simplification on nec benchmarks.
-- After ite simplification, if the ite simplifier was used many times and the NodeManager's node pool is large enough, this garbage collects: zombies from the NodeManager repeatedly, the ite simplification caches, and the theory rewrite caches.
- TheoryEngine
-- Added TheoryEngine::donePPSimpITE() which orchestrates a number of ite simplifications above.
-- Switched UnconstrainedSimplifier to a pointer.
- RemoveITEs
-- Added a heuristic for checking whether or not a node contains term ites and if not, not bothering to invoke the rest of RemoveITE::run(). This safely changes the type of the cache used on misses of run. This cache can be cleared in the future. Currently disabled pending additional testing.
- TypeChecker
-- added a neverIsConst() rule to the typechecker. Operators that cannot be used in constructing constant expressions by computeIsConst() can now avoid caching on Node::isConst() calls.
- Theory Bool Rewriter
-- Added additional simplifications for boolean ites.
Minor Changes:
- TheoryModel
-- Removed vestigial copy of the ITESimplifier.
- AttributeManager
-- Fixed a garbage collection bug when deleting the node table caused the NodeManager to reclaimZombies() which caused memory corruption by deleting from the attributeManager.
- TypeChecker
-- added a neverIsConst() rule to the typechecker. Operators that cannot be used in constructing constant expressions by computeIsConst() can now avoid caching on Node::isConst() calls.
-NodeManager
-- Added additional functions for reclaiming zombies.
-- Exposed the size of the node pool for heuristics that worry about memory consumption.
- NaryBuilder
-- Added convenience classes for constructing associative and commutative n-ary operators.
-- Added a pass that turns associative and commutative n-ary operators into binary operators. (Mostly for printing expressions for strict parsers.)
