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)

2018-10-16Renamed klee/CommandLine.h to klee/SolverCmdLine.h, since this file is meant ↵Cristian Cadar
to have only solver options.

change)

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>

2017-10-04Remove Autoconf/Makefile build system and adjust the TravisCIDan Liew

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.

2016-11-18[CMake] Remove use of tabs in `CMakeLists.txt` files.Dan Liew
2016-11-18[CMake] Re-express LLVM and KLEE library dependencies asDan Liew
transitive dependencies on KLEE's libraries rather than on the final binaries. This is better because it means we can build other tools that use KLEE's libraries and not need to express the needed LLVM dependencies. It also makes it clearer what the dependencies are between KLEE libraries. This has illustrated a problem with the `kleeBasic` library. It contains `ConstructSolverChain.cpp` which clearly belongs in `kleaverSolver` not in `kleeBasic`. This will be fixed later.
