2017-02-07	Generalize finite bound inference to unifiable variables in set membership ↵	ajreynol
	literals.
2017-01-30	Fix regexp cache issue in strings, add regression.	ajreynol

2017-01-18	Fix non-idempotent rewrite in Array rewriter	Andres Noetzli
	This commit fixes bug 637 ( http://church.cims.nyu.edu/bugzilla3/show_bug.cgi?id=637 ) as proposed in Bugzilla and adds the minified test case to the regression tests.
2017-01-11	Merge pull request #129 from timothy-king/regression-scrubber	Clark Barrett
	Adding regression test scrubbing.
2017-01-11	Fix for when variables are (partially) bound in multiple ways, add ↵	ajreynol
	regression. Improve printing for bound int module. Track when relations are enabled in sets, set incomplete if card+rels are both enabled since model construction is not guaranteed to succeed.
2017-01-10	Adding regression test scrubbing.	Tim King

2017-01-05	Disabling a regression test that assumes CVC4 is configured with proofs on. ↵	Tim King
	Modifying the travis rules so there are instances with proofs disabled.
2017-01-04	Fix for tff type declarations inTPTP parser, fixes bug 748. Other minor ↵	ajreynol
	changes.
2017-01-04	Marking regression test files as non-executable.	Tim King

2017-01-04	Reverting two files encoding with DOS linebreaks back into using unix ↵	Tim King
	linebreaks.
2016-12-16	Fix dependency tracing for fewerPreprocessingHoles	Andres Notzli
	Previously, dependency tracing in `ite_removal.cpp` was only done with the `unsatCores` option but `fewerPreprocessingHoles` requires dependencies, too. This lead to errors during proof construction when `fewerPreprocessingHoles` was active. This commit fixes the condition and includes a test case that previously failed. Additionally, it fixes a similar issue in the theory engine. NOTE: this commit might not fix all instances of this problem. `smt_engine.cpp` turns certain flags off with `unsatCores`. Compatibility between those flags and `fewerPreprocessingHoles` needs to be checked separately.
2016-12-12	Fix split-find-unsat-w-emp test	Andres Notzli
	Commit 2f2e9fcf1fbb27f8e799aeac2372c0a9113f01aa did not update the split-find-unsat-w-emp test, this commit fixes that.
2016-12-08	Fix (inactive) `MultSlice` rewrite	Andres Notzli
	The `MultSlice` rewrite was previously accepting multiplications of three and more variables even though it was designed for multiplications of two variables only. Fortunately, the rewrite was not actively used in the bitvector solver. This commit strengthens the condition in `applies()` and adds a unit test that checks that x * y * z and x * y do not get rewritten to the same term.
2016-12-08	Enable remaining cardinality benchmarks	ajreynol

2016-12-07	Add missing regression	ajreynol

2016-12-02	Refactor preprocessing of models in fmf. Fix options --fmf-empty-sorts and ↵	ajreynol
	--fmf-fun-rlv, fixes bug 723.

	minor changes.
2016-11-30	Remove wrong `ExtractMultLeadingBit` rule	Andres Notzli
	The rule `ExtractMultLeadingBit` estimated the number of leading zeros wrong: when there were ones in the leading constant parts of the factors, it was using the length of the non-zero part instead of the length of the zero part. This commit includes an example for which the previous version of the rule would cause a wrong answer.

	Fix parsing of BVROTR by CVC parser
2016-11-30	Fix parsing of BVROTR by CVC parser	Andres Notzli
	This commit fixes Bugzilla bug 766 as proposed by jacobly.alt@gmail.com.
2016-11-30	Add unit test for `MultDistrib` rule	Andres Notzli
	This unit test checks that the issue fixed by commit c0c424283c12cfce2874ea92188487d91acecdf3 has been resolved.
2016-11-21	Remove unused, libstdc++-exclusive include	Andres Notzli
	The file `ext/stdio_filebuf.h` does not seem to be available in libc++, which made compilation of the unit tests for macOS unnecessarily complicated given that it is not used anyway.
2016-11-18	Fix for unit test after changing default "all supported" logic name.	Clark Barrett

2016-11-18	Merge pull request #110 from 4tXJ7f/fix_makefiles	Clark Barrett

2016-11-17	Fix Makefiles in test	Andres Notzli
	With the recent changes to the regress tests, some of the Makefiles were not in sync anymore. This commit fixes that.

2016-11-12	Fixed a bug in cdhashmap in which doubly-linked list was not properly ↵	Clark Barrett
	cleaned up on a call to obliterate. Also, removed some experimental code and a unit test from cdmap_black that used it. This test created a CDList in context memory which seems like a very bad idea (and it was improperly implemented resulting in a memory leak).
2016-11-11	Adding garbage collection for the CVC Parser for Commands when exceptions ↵	Tim King
	are thrown.
2016-11-11	Merge pull request #105 from timothy-king/delete-maxed-out	Tim King

2016-11-10	Adding garbage collection of nodes with maxed out reference counts.	Tim King

2016-11-08	Add a few options to separation logic and sets. Minor changes to separation ↵	ajreynol
	logic, change syntax for empty heap constraint.
2016-11-07	Disabling out of memory tests unit tests when ASAN is enabled. ASAN failures ↵	Tim King
	are too hard for the unit testing framework.
2016-11-07	Changing ArrayStoreAll's constructor to delay allocation until it is done ↵	Tim King
	checking error conditions. This prevents a memory leak in exception throwing branches.
2016-11-07	Fixing a memory leak in the CnfStream unit tests.	Tim King

2016-11-04	Fix three leaks in unit tests	Andres Notzli
	The `testMultipleCollection` test case was allocating a ListenerCollection without deleting it. The helper function `countCommands` was not deleting the `Command`s returned from `InteractiveShell::readCommand`. In the `testEmptyFileInput` and `testSimpleFileInput` tests, the `filename` string was not deleted. This commit fixes all issues.
