Bug-related:
* ITE removal fixed to be context-dependent (on UserContext).
Resolves incrementality bugs 376 and 396 (which had given wrong answers).
* some bugfixes for incrementality that Dejan found (fixes bug 394)
* fix for bug in SmtEngine::getValue() where definitions weren't respected
(partially resolves bug 411, but get-model is still broken).
* change status of microwave21.ec.minimized.smt2 (it's actually unsat, but
was labeled sat); re-enable it for "make regress"
Also:
* --check-model doesn't fail if quantified assertions don't simplify away.
* fix some examples, and the Java system test, for the disappearance of the
BoolExpr class
* add copy constructor to array type enumerator (the type enumerator
framework requires copy ctors, and the automatically-generated copy ctor
was copying pointers that were then deleted, leaving dangling pointers in
the copy and causing segfaults)
* --dump=assertions now implies --dump=skolems
* --dump=assertions:pre-<PASS> and --dump=assertions:post-<PASS> now allow
you to dump before/after a particular preprocessing pass. E.g.,
--dump=assertions:pre-ite-removal or --dump=assertions:post-static-learning.
"--dump=assertions" by itself is after all preprocessing, just before CNF
conversion.
* minor fixes to dumping output
* include Model in language bindings
Minor refactoring/misc:
* fix compiler warning in src/theory/model.cpp
* remove unnecessary SmtEngine::printModel().
* mkoptions script doesn't give progress output if stdout isn't a terminal
(e.g., if it's written to a log, or piped through less(1), or whatever).
* add some type enumerator unit tests
* de-emphasize --parse-only and --preprocess-only (they aren't really "common"
options)
* fix some exception throw() specifications in SmtEngine
* minor documentation clarifications
