2010-05-31First draft implementation of mkAssociativeChristopher L. Conway
2010-05-29Adding a couple of example from fuzzsmt to regress1.Tim King
2010-05-29Couple of fixes to theory arith. pivotAndUpdate now multiplies by a_kj. And ↵Tim King
the tableau now simulates older pivots while adding a new row.
2010-05-29After blasting the disjuncts, TheoryEngine rewrite needs to reinvoke itself. ↵Tim King
QF_LRA is now no longer complaining about seeing nodes that can be rewritten to CONST_BOOLEAN.
2010-05-28This update enables TheoryArith to accept assertions that rewrite to true or ↵Tim King
false. This is temporary and will be removed once TheoryEngine rewriting is more fully debugged.
2010-05-28Bug fixes for combining coefficients of rewritten nodes.Tim King
2010-05-28Added printModel() to src/theory/arith/partial_model.cpp. This is a ↵Tim King
debugging utility that prints out the lower bound, upper bound, assignment, and the constraints that were asserted that caused the lower bound and upperbound to be asserted.
2010-05-28A few changes to the organization of TheoryEngine rewriting. A few bug fixes ↵Tim King
for it as well. make check should now work again.
2010-05-28Moving the ITE removal from CnfStream to TheoryEngine, which is a bit closer ↵Tim King
to its final destination. Added a basic rewriter to TheoryUF. (x=x rewrites to true.) Added DIVISION to src/expr/node_manager.cpp's getType. Fixed the theory returned for variables in theoryOf() for bool and arith. Fixed TheoryEngine rewrite children to properly handle APPLY_UFs. Removed the special case for equality in TheoryEngine rewrite. A few tests are currently broken due to deallocation errors. Morgan and I will try to commit a fix to this in a little bit.

potential design for later. Resolves bug 113, invalidates bugs 93 and 94.
2010-05-27fix compiler comparison-signedness warningsMorgan Deters
2010-05-27Reverting this file to not include any comments. (Morgan's revision and my ↵Tim King
revision were in conflict.)
2010-05-27added the ability to add custom expected stdout, stderr, and exit codes to ↵Morgan Deters
smt and smt2 regressions; resolves bug 132
2010-05-27Preregistration has been turned on. Highly experimental eager splitting ↵Tim King
support has been added. Also a few bug fixes to Tableau.
2010-05-27Use the newer automake test driver "parallel-tests". This driver:Morgan Deters
* keeps test logs around * provides parallel testing functionality (with make -jN). I've also added new functionality in test/Makefile.am which deletes old test logs, ensures that ALL tests are tried (even if units fail), and provides a color-coded summary at the end of the test run, which shows how many units, regressions (per level), and system tests failed (or passed), and provides a link to the log file for further information. Resolves bug 117.

2010-05-26CDMap<> and CDOmap<> fixes to resolve bug 123Morgan Deters
2010-05-26Fix for bug 131. Added some additional debugging assertions for the arith ↵Tim King
rewriter.
2010-05-26CDMap: fix bug 130Morgan Deters
2010-05-26Prevent lexer errors being raised if a parser error is pending.Christopher L. Conway
This fixes a bug Dejan has often whined about but never filed.
2010-05-25Added Rational constructors that only take a numerator. The const char* ↵Tim King
Rational and Integer constructors are now explicit. This means that 'Integer = 3;' and so on are no longer permitted. This closes bug 121.
2010-05-25Some initial changes to allow for lemmas on demand. Dejan Jovanović
To be done: * Add erasable map Clause* to bool to minisat (backtracks with the solver) * Add map from Clause* to Node (clauses that came from a node) * Add reference counting Literal -> Node to CNFManager * If Literal -> Node refcount goes to zero, the clauses of Node can be erased (if eresable) * If clause is erased for each L in clause L -> Node refcount goes down
2010-05-21Small fixes to TheoryArith. Added a hack to make Integers a subtype of ↵Tim King
Real. See Bug 127 for a discussion of the hack. I am also adding a regression test that does not work (bug 128). It is not enabled so make check should still be fine.
2010-05-20Added the division symbol to the parser, and minimal support for it in ↵Tim King
TheoryArith. Also directly hacked in support for theoryOf() to work for equalities where the left hand is a variable of type real.
2010-05-19Significant revision to theory/arith. The new draft has a lot of small bug ↵Tim King
fixes and organizational changes. The theory is now enabled to perform checking in the TheoryEngine. This draft can now solve 2 new regression tests test/regress/regress0/ineq_slack.smt and test/regress/regress0/ineq_basic.smt. There is also a small bug fix inside src/expr/attribute.h.
