cvc5.git - CVC4 is an efficient open-source automatic theorem prover for satisfiability modulo theories (SMT) problems.

2012-08-22	Cap finite cardinalities at 2^64, as discussed in the meeting last week.	Morgan Deters
	Replace all cardinality comparison functions <=, ==, !=, >=, <, >, with a single compare() function that can return UNKNOWN in the case of unknown (or large-finite and thus not precisely known) cardinalities.
2012-08-22	fix some build dependencies in options-building; should fix a strange bug ↵	Morgan Deters
	Andy saw when adding options & re-making, which was caused by sources not being properly recompiled when they should be
2012-08-22	More progress on array constants.	Clark Barrett
	Here's a fun way to give yourself a week-long headache: try to figure out how to write efficient code to normalize array constants. It's mostly there now - just need to figure out how to use type enumerators and update once the new cardinality stuff is in place.
2012-08-21	add some incremental in-tree regressions	Morgan Deters

2012-08-21	rewriterules: fix a correction bug with --simplification=batch	François Bobot
	Rewriterules used ppAssert to obtain early the rewriterules in order to use them in ppRewrite. But all the simplifications (ex. f x = b : [f x/b]) are not done at that point. Since --simplification=batch remove the equality (unlike =incremental), for reachability_bbttf_eT_arrays.smt2 the answer was sat instead of unsat (thx Andy). Partial fix: don't take the rewriterules during ppAssert. That changes nothing since early rewrite was already disabled. But the complete fix (when early rewrite will be enabled again) will need to take the rewriterules more than once.
2012-08-20	remove duplicate function TheoryEngine::getTheory(TheoryId). It was a ↵	Morgan Deters
	duplicate of TheoryEngine::theoryOf(TheoryId)

2012-08-20	fixes for java bindings	Morgan Deters

2012-08-19	1. Fix for inst_match.cpp to allow compilation on fedora	Clark Barrett
	2. Initial implementation of computeIsConst for arrays - still needs additional checks based on cardinality 3. Finally fixed pre-competition bug in array rewriter 4. Still to come: array rewrites for constants and STORE_ALL
2012-08-16	The SmtEngine now ensures that setLogicInternal() is called even if there is ↵	Morgan Deters
	no explicit setLogic(). This is important for the CVC language, where the parser doesn't ensure that setLogic() is called, and for API uses. setLogicInternal() should be called in order to properly set up heuristics, even if the logic is just ALL_SUPPORTED. This means that the CVC language can now take advantage of statistics. Also added the ability to set the logic from CVC presentation language via (e.g.) OPTION "logic" "QF_UFLIA"; Disabled the justification decision heuristic for ALL_SUPPORTED, as it interferes with incrementality. Kshitij may have a fix (I warned him about this commit).
2012-08-16	Replace propagateAsDecision() with Theory::getNextDecisionRequest():	Morgan Deters
	* arrays now uses the new approach by using a CDQueue<> * uf strong solver has had the feature disabled, pending a merge from Andy * theory kinds files now have a getNextDecisionRequest property (if you want to take part in such decision requests you have to list that property) * the staticLearning property has been renamed ppStaticLearn to match the function name * theory kinds files are now checked again for correctly-declared properties (this had been disabled) * minor documentation and other fixups
2012-08-16	ArrayStoreAll should (for now) only allow constant expressions, as it is ↵	Morgan Deters
	itself a CONSTANT.

2012-08-16	some fixes for language bindings	Morgan Deters

2012-08-14	Fixes to integer wrapper classes:	Morgan Deters
	* more uniform interface between the CLN and GMP wrappers * support base inference (base == 0) on parsing strings with the CLN wrapper; this was a difference from the GMP wrapper (resolves bug #372)
2012-08-14	Implements TheoryArith::collectModelInfo(). The current implementation is ↵	Tim King
	quite basic. This may need to be revisited.
2012-08-14	Adds substituteDelta() to DeltaRational which given a value for delta ↵	Tim King
	returns the corresponding rational value.
2012-08-14	Switched TheoryModel assertEqualityEngine to use const Equality Engine pointers.	Tim King

2012-08-14	Switched a number of EqClassIterator operations to const as well as the ↵	Tim King
	internal EqualityEngine pointer.
2012-08-13	fix integer parsing error.. thanks dejan for the report. this indicates ↵	Morgan Deters
	that we have a problem with our Integer class though; it appears to behave differently for GMP and CLN

2012-08-08	Public interface review items:	Morgan Deters
