2023-06-11SpecialFunctionHandler: use std::array for handlerInfoJulian Büning
2023-04-06Support disabling compiler warnings; Use with external headersMartin Nowack
2023-03-23stats: add termination class statsFrank Busse
2022-09-14Support UBSan-enabled binariesPavel Yatcheniy
2022-06-13Update SpecialFunctionHandler.cppChaoqi Zhang
use size() to get N in bind(), just like the way in prepare().
2022-01-05introduce BranchTypesFrank Busse
2022-01-05Remove outdated reference to klee_make_symbolic_nameCristian Cadar
2021-12-23Introduce termination categoriesFrank Busse
Track all path terminations: esp. for debugging or visualising a persistent process tree (with or without full MoKlee integration) it is helpful to know the exact reason (StateTerminationType) why a path terminated.

2020-10-12Implemented support for C++ ExceptionsFelix Rath
We implement the Itanium ABI unwinding base-API, and leave the C++-specific parts to libcxxabi. Co-authored-by: Lukas Wölfer <lukas.woelfer@rwth-aachen.de>
2020-07-01Use constraint sets and separate metadata for timing solver invocationMartin Nowack
Decouple ExecutionState from TimingSolver Instead of providing an execution state to the timing solver use a set of constraints and an additional object for metadata. Fixes: * correct accounting of metadata to a specific state * accounting of all solver invocations (e.g. solver-getRange was not accounted) * allows to invoke the solver without a state (avoids costly copying of states/constraints)
2020-04-30Moved header files that were placed directly in include/klee/ into ↵Cristian Cadar
appropriate existing directories and a new directory Statistics; a few missing renames.

2020-04-08readStringAtAddress: support pointer into objectsMarek Chalupa
The code assumed that the passed pointer points at the beginning of the object. Remove this assumption and support any (constant) pointer. The string is read util either the end of the object is hit (in which case a warning is issued as the string was not zero terminated) or until the terminating zero is found.
2020-04-08readStringAtAddress: use stringstream to obtain the stringMarek Chalupa
The code is simpler and more in the spirit of C++.

2019-09-03Moved solver-related header files into a separate klee/Solver/ directory.Cristian Cadar
2019-05-30remove klee_alias_function()Julian Büning
this function can be used to modify the control flow of the program on different paths, enabling self-modifying code.

2019-03-15Categorized the options in SpecialFunctionHandler.cppCristian Cadar
2018-11-23Implemented memalign with alignmentLukas Wölfer
2018-10-16Renamed klee/CommandLine.h to klee/SolverCmdLine.h, since this file is meant ↵Cristian Cadar
to have only solver options.
2018-07-11Removed support for klee_make_symbolic with 2 arguments. This has been ↵Cristian Cadar
deprecated for many years now and causes problems during replay. Changed and simplified affected test case.
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.

2018-05-15Implemented incomplete mergingLukas Wölfer
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

2017-11-24klee_make_symbolic: warn on deprecated usageFrank Busse
* terminates state instead of using assertion for illegal argument number * renames empty names to "unnamed" (otherwise test generation fails) * deprecates two argument version

2016-08-04klee: add exit-on-error-type parameterJiri Slaby
It allows stopping the execution on some conditions like assertions. The use is like: klee -exit-on-error-type=Assert -exit-on-error-type=External file.llvm This is especially useful in the SV-COMP. A test to cover the new parameter was added too. Signed-off-by: Jiri Slaby <jslaby@suse.cz>

preferences added in the POSIX model. Removed option --prefer-cex which controlled all CEX preferences.
2015-02-13refactor integer overflow detection, add signed intLuca Dariz
Instead of checking for every possible casse which result in overflow, it is much simpler to perform the operation using integers with bigger dimension and check if the result overflow
