2010-11-15Pretty-printer infrastructure created (in src/printer) and SMT-LIBv2 printerMorgan Deters
implemented. This new infrastructure removes support for pretty-printing (even in the AST language) an Expr with reference count 0. Previously, this was supported in a few places internally to the expr package, for example in NodeBuilder. (Now, a NodeBuilder cannot be prettyprinted, you must extract the Node before printing it.)
2010-11-15This commit merges the arith-prop-opt branch into the main trunk. This was ↵Tim King
done by way of the intermediate branch arith-prop-tmp. Both arith-prop-opt and arith-prop-tmp will now be phased out.

2010-10-31small fix to debug segfaultsMorgan Deters
2010-10-31enable dependence graphs in doxygen; fix lots of doxygen warnings, fix some ↵Morgan Deters
documentation, and make it possible to "make doc" on a clean source tree (post-configure)
2010-10-31maximize stack limit, handle SEGV signals on an alternate signal stack, and ↵Morgan Deters
try to diagnose stack overflow
2010-10-30Adds a hueristic from Alberto's thesis. For a fixed window the row count is ↵Tim King
used to select which non-basic variable is a row in made basic.
2010-10-29Fix for a problem caused by using a != instead of == in ↵Tim King
generateConflictBelow(). Resolves a bug introduced in -r1063.
2010-10-29portability updates to build systemMorgan Deters
2010-10-29Adds a very small test that triggers a bug. The bug is from the commit for ↵Tim King
-r1063.
2010-10-29minor fixes as a result of review of Chris's getType() rewrite; also fix ↵Morgan Deters
some macros to make various GCC versions happy
2010-10-29Fixes RowVector::has().Tim King
2010-10-29Factors out the QF_LRA decision procedure from TheoryArith and puts this ↵Tim King
into its own class SimplexDecisionProcedure. Implements about 1/2 of the pivoting rule from Alberto's thesis (section2.5.3).
2010-10-28The Row implementation has no been replaced by RowVector and ↵Tim King
ReducedRowVector. A RowVector is an array of ArithVar and Rational pairs. (This replaces a map based implementation in Row.) ReducedRowVector is a RowVector with a notion of having a basic variable. The Tableau is now a collection of ReduceRowVector's. A major difference between ReducedRowVectors and Rows is that the iterator now includes the basic variable and its coefficient (always -1). Before only nonbasic members were accessible by the iterator.

2010-10-27fix test MakefileMorgan Deters
2010-10-27"make dist" fixes; a distribution tarball can now build and pass tests. ↵Morgan Deters
"make distcheck" fails only because one of the "clean" targets needs work in test/unit

input expression and the second the value (resolves bug 227)

2010-10-24Adding unit test for InteractiveShellChristopher L. Conway
2010-10-24add a CVC4_UNDEFINED keyword, for intentionally undefined functions (like ↵Morgan Deters
private copy constructors and assignment, for instance) that generates better, compile-time error messages if the function is used (before, you'd have to wait until link time); also some minor cleanup
2010-10-23Removed slack.h, and arith_activity.h. Replaced IsBasicManager with the more ↵Tim King
general ArithVarDenseSet. Renamed NextArithRewriter to ArithRewriter.
