2012-05-19	- The array type rules were fixed to use isSubtypeOf.	Tim King
	- The type of (kind::DIVISION x y) is RealType. - A reference to util/pseudoboolean.i was removed. - rec5.cvc is disabled for now. The type of 2 is Integer which is not a subtype of [0..11].
2012-05-18	This commit adds TypeNode::leastCommonTypeNode(). The special case for ↵	Tim King
	arithmetic in TypeNode::operator==() has been removed. A number of faulty type checking checks were switched to use isSubtypeOf. The resolves bug #339
2012-05-18	This commit removes the dead psuedoboolean code.	Tim King

2012-05-18	Removing long unsigned operator+ from CDList's const_iterator.	Tim King

2012-05-18	removing failing regression	Dejan Jovanović

2012-05-17	This fixes a fascinating segfault. This is the sequence of events:	Tim King
	1) A restart occurs 2) A shared term is registered to arithmetic. 3) Arithmetic sets this up. 4) No new linear relations are added to arithmetic. 5) Eventually a restart occurs. 6) Arithmetic resets the tableau as it has not had a row added since the last restart. 7) A new variable is added. 8) This exceeds the size of the column vector of the saved tableau by exactly one. 9) segfault

	QF_UF and maybe others
2012-05-17	Fixed bug 338:	Liana Hadarean

2012-05-17	Queueing up asserted literals in the proxy instead of sending them off to ↵	Dejan Jovanović

2012-05-16	Changes to SAT solver:	Dejan Jovanović
	* allowing propagation of false literals (handles conflict) * allowing lemmas during BCP (bug 337) * UF does direct propagation, without checking for literal value anymore
2012-05-16	equality status for bitvectors can now look into the sat solver to check for ↵	Dejan Jovanović
	IN_MODEL status

2012-05-15	Fixed several bugs in shared terms database	Clark Barrett

2012-05-15	This commit removes the CONST_INTEGER kind from nodes. This code comes from ↵	Tim King
	the branch arithmetic/remove_const_int.
2012-05-15	renamed bv_sat.h, bv_sat.cpp to bitblaster.h, bitblaster.cpp respectively	Liana Hadarean

2012-05-15	removing all extended commands (as inspired by the Z3 extended command set) ↵	Morgan Deters
	except for declare-datatypes
2012-05-15	Fix QF_AUFLIA (resolves bug #331).	Morgan Deters

2012-05-15	fixing warnings, grr	Dejan Jovanović

2012-05-15	several bug fixes: in TheoryBV::NotifyClass missing NOT in predicate notify ↵	Liana Hadarean
	and now term notify handles boolean constants; fixed bug 328
2012-05-14	fixes for shared term registration. previously the type was not considered ↵	Dejan Jovanović
	when looking at theories of the term and for a term like read(a, f(x)) the term f(x) would not be registered to arithmetic in AUFLIA. this fixies the issue of bug 330 and moves it to some other assertion fail.
2012-05-14	Fixed assertion failures in array theory	Clark Barrett
	This fixes bugs 335 and 333.
2012-05-14	in debug builds, -d can be used for trace tags that aren't also debug tags	Morgan Deters

	is created with a Boolean term inside it
2012-05-11	Disabled arith-rewrite-equalities by default unless in a pure arithmetic theory	Clark Barrett

2012-05-11	Added some ITE rewrites,	Clark Barrett
	Added ITE simplifier - on by default only for QF_LIA benchmarks Fixed one bug in arrays Added negate() to node.h - it returns kind == NOT ? kind[0] : kind.notNode()
2012-05-11	Partially fixes something-like-a-problem with TheoryArith::getDeltaValue().	Tim King

2012-05-10	Removing now unneeded (as of r3425) typenames from EqualityEngine. trunk now ↵	Tim King
	compiles on Debian.
2012-05-09	fix an issue which breaks language bindings (so this commit fixes debian ↵	Morgan Deters
	nightly builds)
2012-05-09	--disable-tracing at configure time now disables Trace() and Debug() ↵	Morgan Deters
	gestures both.
2012-05-09	* simplifying equality engine interface	Dejan Jovanović
	* notifications are now through the interface subclass instead of a template * notifications include constants being merged * changed contextNotifyObj::notify to contextNotifyObj::contextNotifyPop so it's more descriptive and doesn't clutter methods when subclassed * sat solver now has explicit methods to make true and false constants * 0-level literals are removed from explanations of propagations
2012-05-09	rm something for a future merge that sneaked in	Kshitij Bansal
	(gets rid of warning)
2012-05-09	Merge from decision branch (ITE support)	Kshitij Bansal
	Major changes from last merge * ITEs supported * Don't share theory lemmas to DE, only assertions Should probably be noted that 'make regress' doesn't quite pass with --decision=justification. Throws off search in couple of arith benchmarks. No serious performance changes expected. Keep an eye.
2012-05-09	Fixing the debug tags generation and related methods in configuration.cpp ↵	Dejan Jovanović
	that disallowed me to debug my bugs by reporting that the debug tag doesn't exists, where in fact it was in the code. 1) The grep and sed for tags wasn't picking up on .isOn("tag") 2) The isDebugTag a) didn't take a parameter b) was using binary search using strcmp which is non-portable and didn't work for tags including special characters Morgan should vet this, since there is some crazy sed stuff going on
2012-05-08	Merging in bvprop branch, with proper bit-vector propagation.	Liana Hadarean
	This should also fix bug 325.
2012-05-07	Fixing a bug with TheoryArith::ppAssert() and shared terms.	Tim King

2012-05-07	Fixes a sign bug in the DioSolver.	Tim King
