2019-10-31support compilation against LLVM 9.0Julian Büning
2019-09-03Moved solver-related header files into a separate klee/Solver/ directory.Cristian Cadar
2019-09-03Moved ConstructSolverChain.cpp to the Solver library.Cristian Cadar
2019-09-03Renamed CmdLineOptions.cpp to SolverCmdLine.cpp (in line with the associated ↵Cristian Cadar
header SolverCmdLine.h) and moved it to the Solver library.
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)
2018-10-23refactor klee_open_output_file to return std::unique_ptrJulian Büning
and introduce klee_open_compressed_output_file with similar behavior along some other minor improvements
2018-10-23use klee_open_output_file for uncompressed logsJulian Büning
2018-10-16Renamed klee/CommandLine.h to klee/SolverCmdLine.h, since this file is meant ↵Cristian Cadar
to have only solver options.
2018-09-20Silence an uninitialized variable compiler warning (and a tiny formatting ↵Cristian Cadar
change)
2018-07-04Fix compiler warnings if assertions are disabledMartin Nowack
2018-05-21stop using DEBUG macro nameJiri Slaby
This is too generic and llvm 6.0 defines DEBUG as follows: #define DEBUG(X) DEBUG_WITH_TYPE(DEBUG_TYPE, X) This then results in various build failures where once the macro is defined, once it is not. So rename this generic macro to KLEE_ARRAY_DEBUG. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>

2018-05-09Improve handling of constant array in Z3Timotej Kapus
2017-10-17[cmake] detect available metaSMT backends using a pre-defined flag and raise ↵Hoang M. Le
compile flags accordingly
2017-10-17add support for CVC4 and Yices2 via metaSMTHoang M. Le
2017-10-04Remove Autoconf/Makefile build system and adjust the TravisCIDan Liew
configuration, TravisCI scripts and Dockerfile build appropriately. There are a bunch of clean ups this enables but this commit doesn't attempt them. We can do that in future commits.
2017-07-08Corrected comment of Z3Solver classAndrew Santosa
2017-06-02hide backend solver declarations from public includeHoang M. Le
2017-06-02replace handleMetaSMT() with klee::createMetaSMTSolver() and move it into ↵Hoang M. Le
MetaSMTSolver.cpp so that the backend headers only need to be included once there
2017-06-01[Z3] Remove unused include.Dan Liew
2017-06-01[Z3] Add `-debug-z3-verbosity=<N>` option which behaves like Z3's `-v:<N>` ↵Dan Liew
option. This lets us see what Z3 is doing execution (e.g. which tactic is being applied) which is very useful for debugging.
2017-06-01[Z3] Switch from `Z3_mk_simple_solver()` to `Z3_mk_solver()`.Dan Liew
My discussions [1] with the Z3 team have revealed that `Z3_mk_simple_solver()` is the wrong solver to use. That solver basically runs the `simplify` tactic and then the `smt` tactic. This by-passes Z3's attempt to probe for different logics and apply its own specialized tactic. Using `Z3_mk_solver()` should be closer to the behaviour of the Z3 binary. This partially addresses #653. We still need to try rolling our own custom tactic. [1] https://github.com/Z3Prover/z3/issues/1035
2017-06-01[Z3] In `getConstraintLog()` use a separate builder from that of theDan Liew
solver. This is to avoid tampering with the cache of the builder the solver is using.
2017-06-01[Z3] Implement API logging.Dan Liew
Add `-debug-z3-log-api-interaction` option to allow Z3 API calls to be logged to a file. The files logged by this option can be replayed by the `z3` binary (using its `-log` option). This is incredibly useful because it allows to exactly replay Z3's behaviour outside of KLEE.
2017-06-01[Z3] Add option to manually validate Z3 models.Dan Liew
This can be enabled by passing the command line option `-debug-z3-validate-models`. Although Z3 has a global parameter `model_validate` (off by default) I don't trust it so do the validation manually. This also means we can potentially do validation on a per Z3Solver instance basis rather than globally. When failing to validate a Z3 model the solver state and model are dumped to standard error.
2017-06-01[Z3] Add the `-debug-z3-dump-queries=<path>` command line option. ThisDan Liew
is useful for getting access to the constraints being stored in the Z3 solver in the SMT-LIBv2.5 format.
2017-06-01[Z3] Move the `dump()` methods of the Z3NodeHandle<> specializationsDan Liew
into `Z3Builder.cpp` so they can be called from in gdb.
2017-06-01[Z3] Add assertions in Z3 builder to catch underflow with bad widths.Dan Liew
2017-06-01[Z3] Support another solver failure reason that Z3 might give. I'm goingDan Liew
to guess it means timeout but I'm not 100% sure about this.
2017-05-24llvm: make KLEE compile against LLVM 3.5 and 3.6Richard Trembecký
Based on work by @ccadeptic23 and @delcypher. Formatting fixed by @snf. Fix compiler warning by @martijnthe. Further fixes by @mchalupa. Refactored, so that changes can be reviewed -- no massive changes in whitespace and in the surrounding code. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2017-03-23[CMake] Unbreak build due to not adding AssignmentValidatingSolver.cppDan Liew
to list of source files. The cause of the breakage was me being to eager and merging #468 before forcing tests to re-run. That PR was written before the CMake build system existed.
2017-03-23Add `AssignmentValidatingSolver`. It's purpose is to check any computedDan Liew
assignments against the corresponding `Query` object and check the assignment evaluates correctly. This can be switched on using `-debug-assignment-validating-solver` on the command line.

2017-02-22klee: remove use of deprecated 'register'Jiri Slaby
New compilers warn about using 'register' as follows: ConstantDivision.cpp:66:3: warning: 'register' storage class specifier is deprecated and incompatible with C++1z [-Wdeprecated-register] Remove the register specifier -- the compilers are clever enough to know what to do.
