2019-09-03Moved solver-related header files into a separate klee/Solver/ directory.Cristian Cadar
2019-07-30Consolidated Expr-related include files into a single include/klee/Expr ↵Cristian Cadar
directory. This improves the organization of the code, and also makes it easier to reuse Expr outside KLEE.
2018-10-30Base time API upon std::chronoFrank Busse
This should not change the behaviour of KLEE and mimics the old API. - functions moved from util into time namespace - uses time points and time spans instead of double - CLI arguments now have the form "3h5min8us" Changed command line parameters: - batch-time (double to string) - istats-write-interval (double to string) - max-instruction-time (double to string) - max-solver-time (double to string) - max-time (double to string) - min-query-time-to-log (double to string) - seed-time (double to string) - stats-write-interval (double to string) - uncovered-update-interval (double to string) - added: log-timed-out-queries (replaces negative max-solver-time)
2016-01-12Drop unnecessary ``#include``s from Solver.cpp.Dan Liew
2016-01-12Refactor MetaSMTSolver and MetaSMTSolverImpl out of Solver.cpp intoDan Liew
their own file ``MetaSMTSolver.cpp``. Whilst I'm here also clang-format the modified code. This might not be a NFC (non functional change) as there's a good chance this has broken the MetaSMT build of KLEE. I don't have a build of MetaSMT to hand and there is no TravisCI build. At this point because there is no maintainer for this code I think we should consider removing it as it is going bitrot.
2016-01-12[NFC] Refactor STPSolver and STPSolverImpl out of Solver.cpp into theirDan Liew
own file ``STPSolver.cpp``. Whilst I'm here also clang-format the modified code.
2016-01-12[NFC] Refactor DummySolver out of Solver.cpp into its own fileDan Liew
``DummySolver.cpp``. Whilst I'm here also clang-format the modified code.
2016-01-12[NFC] Refactor ValidatingSolver out of Solver.cpp into its own fileDan Liew
``ValidatingSolver.cpp``. Whilst I'm here also clang-format the modified code.
2016-01-07[NFC] Refactor SolverImpl out of Solver.cpp into its own fileDan Liew
(SolverImpl.cpp). Whilst I'm here also clang-format the modified code.
2015-12-18Move lib/Solver/SolverStats.h -> include/klee/SolverStats.hDan Liew
so that it is possible to ``#include "klee/util/ArrayExprHash.h"``
2015-12-17[Solver]Add support to dump STP qeries usingMartin Nowack
Use "-debug-dump-stp-queries" argument for KLEE/Kleaver to print out each STP query sent to the STP Solver. Queries have the format which `stp` frontend can understand.
2015-12-17[Solver]Add simple option to dump queriesMartin Nowack
2014-09-13[Solver] Tune down the shared memory region size on Darwin.Daniel Dunbar
- See comment, this is a gross workaround for Darwin's very small default limit on shared memory size. I'm not sure how big of a counterexample users can actually expect STP to solve in practice -- if there is a practical use for larger ones it would probably be good for us to write a fallback strategy.
2014-09-13[Solver] Ensure shared memory allocation failures are reported as errors, ↵Daniel Dunbar
not asserts.
2014-05-29Remove #include <iostream> to avoid static constructorsMartin Nowack
iostream injects static constructor function into every compilation unit. Remove this to avoid it.
2014-04-24Remove unused pointer to STPSolver in STPSolverImpl to silence clangDan Liew
warning.
2014-04-16Removing a few more hard-coded values for domains and ranges of Array objectsHristina Palikareva
2013-10-11getConstraintLog() of MetaSMTSolver explicitly states that this feature is ↵Hristina Palikareva
not supported; a test case modified to not fail because of this.
2013-10-11MetaSMT builder, solver and command-line options.Hristina Palikareva
2013-08-06Methods getConstraintLog() and setTimeout() made virtual and moved from ↵Hristina Palikareva
STPSolver to base Solver and SolverImpl classes, and consequently redefined in derived classes to call the corresponding methods down the solver chain. Method setTimeout() renamed to setCoreSolverTimeout().
2013-01-22Added a new option --ignore-solver-failures, disabled by default, toCristian Cadar
cause KLEE to terminate on fatal solver errors. Better documented the ulimit issue when STP seg faults. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@173187 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Patch by Tomasz Kuchta adding more detailed information on query failures.Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@171391 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Patch by Tomasz Kuchta adding a new option (min-query-time-to-log) that ↵Cristian Cadar
enables KLEE to log only the queries exceeding a certain duration, or only those that time out. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@171385 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-31Patch by Dan Liew that removes our internal copy of STP, and makes the ↵Cristian Cadar
--with-stp option mandatory: "1. At configure time the --with-stp= option is now mandatory. 2. The HAVE_EXT_STP macro has been removed. 3. The ENABLE_EXT_STP autoconf replacement variable has been removed and consequently the Makefile variable of the same name has been removed." git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@161055 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-11Patch by Ben Gras fixing a few minor issues: adds missing includes,Cristian Cadar
fixes the ntohs prototype in klee-libc, and removes some unused code. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@146352 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-14Add option to use an external version of STPPeter Collingbourne
This patch adds a new configure option, --with-stp, which configures KLEE to use an external version of STP instead of the version in the source tree. It includes documentation referring users to the STP download location. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@108347 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-22Added --stp-optimize-divides flag. Patch submitted by PeterCristian Cadar
Collingbourne: "This flag controls whether constant divides are optimized into add/shift/multiplies before passing to STP, and is set by default. In some circumstances the use of this optimisation can actually slow the solver down, so it is best to allow the user to disable it." git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@102069 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-24Applied the patch submitted by Robby Cochran that fixes an arithmetic ↵Cristian Cadar
overflow in Solver::getRange(). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@79945 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-01Avoid failing if waitpid fails with EINTR, patch by Vladimir Kuznetsov.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77770 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10Replaced createNot() by createIsZero() and "Not" macro by "Nz". Cristian Cadar
Not will become bitwise not. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@75224 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Add ConstantExpr::{getLimitedValue,getZExtValue}.Daniel Dunbar
- For use in situations where the range of the constant is known to fit in a uint64 (or smaller), or the extra bits don't matter. - No (intended) functionality change. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73326 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Add several ConstantExpr utility functions and move clients over.Daniel Dunbar
- Reducing uses of getConstantValue() so we can move to arbitrary precision constants. - No (intended) functionality change. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73324 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09More constant Array support.Daniel Dunbar
- The are parsed, printed, and solved now. - Remove some members of ArrayDecl which are only duplicates of Array members. - KLEE still doesn't create these, but you can write them by hand. The EXE style constant array optimization for STP (turning the initial writes into asserts) is now only a stones throw away, but I need to leave something fun to do tomorrow. :) git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73133 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Kill off UpdateList::isRooted flag.Daniel Dunbar
- The right way to handle this is by using constant arrays, where the semantics are easier to define and implement. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73124 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08Add klee::createDummySolver, the dummy solver always fails.Daniel Dunbar
- Useful as an alternative backend to STP for testing. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73048 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-05Clean up a number of unused variable warnings when building w/oDaniel Dunbar
asserts. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72924 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Change Solver::getValue to make explicit that result is a ConstantExpr.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72860 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Finish removing uses of Expr::isConstant.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72859 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Start removing uses of Expr::isConstant.Daniel Dunbar
- These should use cast<>, isa<>, or dyn_cast<> as appropriate (or better yet, changed to use ref<ConstantExpr> when the type is known). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72857 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Move isConstant from ref<> to Expr::Daniel Dunbar
- Ref.h is now freestanding. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72824 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-03Kill off specialized ref<> forwarding methods, in the interest of making it aDaniel Dunbar
more standard reference counting wrapper. - The only interesting changes here are in Ref.h, everything else is just updating foo.method to use foo->method instead. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72777 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-02Use ConstantExpr::alloc instead of ref<Expr> directlyDaniel Dunbar
- The "constant optimization" embedded inside ref<Expr> is going away. - No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72730 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-25Add includes to get sprintf (STPBuilder) andDuncan Sands
fprintf, stderr etc (Solver) when compiling with gcc-4.4. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72381 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-22Add missing include (for FreeBSD build)Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72270 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-21Initial KLEE checkin.Daniel Dunbar
- Lots more tweaks, documentation, and web page content is needed, but this should compile & work on OS X & Linux. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72205 91177308-0d34-0410-b5e6-96231b3b80d8
