* Fixed hole in arrays typechecking.
* Fixed "make dist".
* Better ouroborous test, and some printer fixes.
* Continued cleanup in CVC parser, removed some warnings.
* Better output.

Expected performance impact outside of datatypes/CVC parser is
negligible.
* CVC language LAMBDA, functional LET, type LET, precedence fixes,
bitvectors, and arrays, with partial parsing support also for
quantifiers, tuples, subranges, subtypes, and records
* support for complex recursive DATATYPE selectors, e.g.
tree = node(children:ARRAY INT OF tree) | leaf(data:INT)
these are complicated because they have to be left unresolved
at parse time and dealt with in a second pass.
* bugfix for Exprs/Types that occurred when setting them to null
(not Nodes/TypeNodes, just Exprs/Types).
* Cleanup/code review items

* Makes Options an "omnipresent thread-local global" (like the notion
of the "current NodeManager" was already). Options::current() accesses
this structure.
* Removes Options from constructors and data structures everywhere
(this cleans up a lot of things).
* No longer uses StatisticsRegistry statically. An instance of the
registry is created and linked to a NodeManager.
* StatisticsRegistry::current() is similar to Options::current(), but
the pointer is stowed in the NodeManager (rather than stored)
* The static functions of StatisticsRegistry have been left, for backward
compatibility; they now use the "current" statistics registry.
* SmtEngine::getStatisticsRegistry() is a public accessor for the
registry; this is needed by main() to reach in and get the registry,
for flushing statistics at the end.

are somewhat disparate but belonged on the same branch because they were
held back from trunk all for the same reason (to keep the trunk stable
for furious bitvector development). Dejan has now given me the go-ahead
for a merge.
=========================================
THIS COMMIT CHANGES THE THEORY INTERFACE!
=========================================
Theory constructors are expected to take an additional "Valuation*"
parameter that each Theory should send along to the base class
constructor. The base class Theory keeps the Valuation* in a
d_valuation field for use by it and by its derived classes.
Theory::getValue() no longer takes a Valuation* (it is expected
to use d_valuation instead). This allows other theory functions
to take advantage of getValue() for debugging or heuristic
purposes.
TODO BEFORE MERGE TO TRUNK:
****implement BitIterator find() in CDAttrHash<bool>.
Specifically:
* Added QF_BV support for SMT-LIB v2.
* Two adjustments to the theory interface as requested by Tim King:
1. As described above.
2. Theories now have const access to the fact queue through base
class functions facts_begin() and facts_end(); useful for
debugging.
* Added an "Asserted" attribute so that theories can check if something
has been asserted or not (and therefore not propagate it). However, this
has been disabled for now, pending more data on the overhead of it, and
pending discussion at the 3/25/2011 meeting.
* Do not define NDEBUG in MiniSat in assertion-enabled builds (so
that MiniSat asserts are evaluated).
* As a result of the new MiniSat assertions, some --incremental
regressions had to be disabled; also, some bitvectors ?!!
* Bug 71 is resolved by adding a specialization for CDAttrHash<> in the
attribute package.
* Fixes for some warnings flagged by clang.
* System tests have arrived! So far mainly infrastructure for having
system tests, but there is a system test aimed at improving code
coverage of the printer package.
* Minor other adjustments to documentation and coding to be more
conformant to CVC4 policy.
Tests have been performed to demonstrate that these changes have no or
negligible effect on performance. In particular, changing the
CDAttrHash<> doesn't have any real effect on performance or memory right
now, since there is only one context-dependent boolean flag (as soon
as another is added, the effect is noticeable but probably still slight).

bug217.smt2 as regressions; fix to build system to only run regressions (not units) if you "make -C test regress", for example (this matches behavior elsewhere)
|
|
* add Stats black-box unit test
* new make target: "make units" now runs unit tests only
* revised make target: "make regress" now runs regressions only
* configure.ac: pull in librt for clock_gettime()

* implement zombification and garbage collection of NodeValues
(but GC not turned on yet)
* implement removal of key nodes from all attribute tables
* audit NodeBuilder and fix memory leaks and improper reference-count
management. This is in many places a re-write. Clearly documented
invariants on NodeBuilder state. (Closes Bug 38)
* created a "BackedNodeBuilder" that can be used to construct
NodeBuilders with a stack-based backing store for a size that's not
a compile-time constant.
* NodeValues no longer depend on Node for toStream()'ing
* make unit test-building "silent" with --enable-silent-rules
* (Makefile.am, Makefile.builds.in) fix top-level build system so that
"make regressN" works with unbuilt/out-of-date source trees in the
expected way.
* (various) code cleanup, documentation, formatting
