2018-03-06Merge branch 'master' into cleanup_outputcleanup_outputMathias Preiner
2018-03-05Update semantics for string indexof and replace (#1630)Andrew Reynolds
2018-03-05Fix boost url in contrib/get-win-dependencies.Mathias Preiner
This fixes the broken windows nightly builds.
2018-03-05Enable -Wsuggest-override by default. (#1643)Mathias Preiner
Adds missing override keywords.
2018-03-05Fix for sampler. (#1639)Andrew Reynolds
2018-03-05Add support for check-sat-assuming. (#1637)Aina Niemetz
This adds support for check-sat-assuming. It further adds support for SmtEngine::query() over a vector of Expressions, e.g., smtEngine->query({a, b}); checks the validity (of the current input formula) under assumption (not (or a b)).
2018-03-05Add CVC4_PUBLIC keyword to overloads of << for Expr containers. (#1644)Aina Niemetz
2018-03-05Add uniform way to serialize containers of Expr to stream. (#1638)Aina Niemetz

2018-03-01Create infrastructure for sygus modules (#1632)Andrew Reynolds
2018-02-28SmtEngine::getAssignment now returns a vector of assignments. (#1628)Aina Niemetz
2018-02-27Remove printf from output utilitiesAndres Noetzli
This commit removes the unused printf functions from the output utilities. It also adds `const` keywords where possible. Finally, it removes overloaded `const char*` functions if the same function existed for `const std::string&` and the `const char*` version was only casting the `const char*` to an `std::string`. This conversion happens implicitly, so the `const char*` version is not needed. Note: this commit does not attempt to clean up the macros, something that we should consider in the future.

2018-02-27Remove unused code in pushDefineFunRecScop in smt2.cpp. (#1627)Aina Niemetz

2018-02-27Option to not use partial function semantics for arithmetic div by zero (#1620)Andrew Reynolds
2018-02-27Improvements to sygus sampling (#1621)Andrew Reynolds
2018-02-23Add unit tests for BitVector, minor BV rewrite fix (#1622)Andres Noetzli
This commit adds unit tests for the BitVector class and adds some additional argument checks. Additionally, it fixes a minor issue in the ZeroExtendUltConst rule if the zero_extend was by 0 bits. In that case, the rule was calling BitVector::extract() with high < low.
2018-02-23Split and document bitvector.h. (#1615)Aina Niemetz
2018-02-23Fix cd-simplification for strings (#1624)Andrew Reynolds
2018-02-22Minor improvements to string rewriter (#1572)Andrew Reynolds
2018-02-22Fixed disabling the BV equality slicer for quantifiers. (#1623)Aina Niemetz
This fixes an incorrect condition introduced in #1619 to disable the BV equality slicer.
2018-02-21Disable BV equality slicer if not pure QF_BV. (#1619)Aina Niemetz
2018-02-20Improve documentation of bv::utils::isCoreTerm (#1617)Aina Niemetz
2018-02-20Moved and simplified bv::utils::intersect. (#1614)Aina Niemetz
Tested against the recursive implementation with a temporary assertion on regression tests with --bv-eq-slicer=auto.
2018-02-20Minor fixes and additions for transcendental functions (#1612)Andrew Reynolds
Also adds parsing support for PI in smt2 with syntax "real.pi".
2018-02-20Unrecursified and merged bv::utils::is(Core|Equality)Term. (#1605)Aina Niemetz
This unrecursifies and merges bv::utils::isCoreTerm and bv::utils::isEqualityTerm to avoid code duplication. In the best case, the recursive implementation visits less nodes. This can be achieved with the non-recursive implementation, however, at the cost of increased code complexity. In practice, on QF_BV the new implementation slightly improves performance. Tested against the recursive implementation with a temporary assertion on regression tests (bv::utils::isCoreTerm was tested with --bv-eq-slicer=auto). Further tested on QF_BV with a TO of 300s (slight performance improvement).
2018-02-16bv::utils::mk(And|Or) Do not return true if size of vector is 0. (#1613)Aina Niemetz
2018-02-16Make regress1 default, only test regress0 on Travis. (#1611)Aina Niemetz
2018-02-15Removed bv::utils::mkConjunction (redundant). (#1610)Aina Niemetz
2018-02-15Fix corner case for rewrite of mult by pow 2 (#1601)Andrew Reynolds
2018-02-15Refactor regressions (#1581)Andrew Reynolds
2018-02-15Fix context memory manager unit test (#1609)Andres Noetzli
Commit 83f150c727f197c530d6f46a75b516eea52bed29 changed the flag that we use to determine whether to use the context memory manager or the debug version. However, the change was not reflected in the context memory manager unit test. This commit fixes the unit test to check the correct flag.

2018-02-12Minor improvements to sygus sampler (#1598)Andrew Reynolds
2018-02-11Move (unrecursified) bv::utils::numNodes to lazy_bitblaster.cpp. (#1594)Aina Niemetz
This unrecursifies and moves bv::utils::numNodes to an unnamed namespace in lazy_bitblaster.cpp (only place where it is used). Tested against the recursive implementation (with a temporary Assertion) on regression tests.
