2019-03-05workaround for LLVM PR39177Julian Büning
provides a workaround for LLVM bug PR39177, which affects LLVM versions 3.9 - 7.0.0: https://bugs.llvm.org/show_bug.cgi?id=39177 This commit is intended to be reverted once support for LLVM versions <= 7 is dropped from KLEE.
2018-11-02Introduced a constraint solving option category to which all the options in ↵Cristian Cadar
CmdLineOptions.cpp are currently added.
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)
2018-10-26llvm6: SetVersionPrinter now passes down a streamJiri Slaby
I.e. klee::printVersion should now have a parameter -- the output stream. Change both the prototype and the implementation to handle this properly. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-26llvm5: handle getOrInsertFunction terminatorJiri Slaby
llvm 5 does not terminate getOrInsertFunction parameters with NULL, take care of that. Since commit 9d54400bba7eb04bca80fce97fa170452d19eaf1. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
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
2018-10-23Move unrelated function from ReadExpr classMartin Nowack
2018-10-23Move optimization specific headers away from the project include directoryMartin Nowack
Don't pollute the project include directory with optimization specific headers.
2018-10-23Clean-up headersMartin Nowack
Remove unneeded headers from include files
2018-10-23Use std::unordered collections as we use C++11Martin Nowack
2018-10-23Remove unneeded externsMartin Nowack
2018-10-23optimizeExpr: return the result as return value instead as function argumentMartin Nowack
simplifies code a lot.
2018-10-23Make valueOnly parameter of optimizeExpr explicitMartin Nowack
avoid ambiguity of valueOnly parameter
2018-10-23Fixed compilation of array optimization patch with LLVM >= 4.0Cristian Cadar
2018-10-23Added missing headers and clang-format the filesCristian Cadar
2018-10-23Added support for KLEE value-based array optimizationAndrea Mattavelli
2018-10-23Added support for KLEE index-based array optimizationAndrea Mattavelli
2018-10-16Small changes to commentsCristian Cadar
2018-10-16Added missing header to SolverCmdLine.h and clang-format itCristian Cadar
2018-10-16Renamed klee/CommandLine.h to klee/SolverCmdLine.h, since this file is meant ↵Cristian Cadar
to have only solver options.
2018-10-08add support for klee-replay on OSXFrank Busse
* also adds klee-replay as dependency for systemtests
2018-10-04config.h.cmin: remove obsolete cmakedefineJulian Büning
2018-09-18llvm4: PointerType is not SequentialTypeJiri Slaby
So handle the type specially whenever needed. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-09-18llvm4: use chrono helpers from LLVMJiri Slaby
LLVM 4 removes the old time interface and starts using the C++11's chrono. So switch to that in klee for LLVM 4 too. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-09-06Fix missing includes and declarationsMartin Nowack
2018-07-04Fix uninitialized memory: enums have to be initializedMartin Nowack
2018-07-04Reorder linking and optimizationsMartin Nowack
Link intrinsic library before executing optimizations. This makes sure that any optimization run by KLEE on the module is executed for the intrinsic library as well. Support .ll files as input for KLEE as well.

2018-05-24llvm37: handle GetElementPtrInst::Create's new parameterJiri Slaby
LLVM 3.7 added a PointeeType parameter to GetElementPtrInst::Create. Let's handle that by a macro called KLEE_LLVM_GEP_TYPE, defined in Version.h. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-05-22Renamed printFileLine to getSourceLocation (as suggested by @delcypher) to ↵Cristian Cadar
reflect the fact that it simply returns a string
2018-05-22Simplified printFileLine by using std::to_string, and removed unneeded ↵Cristian Cadar
version that takes an argument a stream
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>

2018-05-09Fix include filesMartin Nowack
2018-05-05Fix handling of errno if external functions are invokedMartin Nowack
If an external function in KLEE is invoked, it might update errno. Previously, the errno specific variable in a state was only updated if it was part of the executed instructions. That opened up a timeframe that increased the likelihood of errno being overwritten by another method call. This patch fixes two issues: * the errno of the KLEE process state is updated before the external function call allowing to detect changes to it later on * after the external call, the memory object of errno is directly updated with its new value, reducing the likelihood to be overwritten by another call Additional features: * Add support for `errno()` for Darwin as well. * Simplified errno handling in POSIX layer
