2018-11-23Implemented memalign with alignmentLukas Wölfer
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.
2018-05-05Fix 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

2017-08-04Removed merging searchersLukas Wölfer
2015-06-03Added an option --readable-posix-inputs which is used to turn on/off the CEX ↵Cristian Cadar
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
2015-02-13Detect overflow of unsigned add, sub and mul operationsLuca Dariz
This requires clang with -fsanitize=unsigned-integer-overflow tested with clang and llvm 3.4.2
2015-02-13Revert "Merged @luckyluke's change for detecting overflow of unsigned add, sub"Cristian Cadar
Will redo the merge to preserve original commits. This reverts commit a743d7072d9ccf11f96e3df45f25ad07da6ad9d6.
2015-02-10Merged @luckyluke's change for detecting overflow of unsigned add, subCristian Cadar
and mul operations. Refactored tests into two main cases, and disabled them on LLVM 2.9, which does not support -fsanitized=*signed-integer-overflow.
2014-02-06Implement const_iterator interface for SpecialFunctionHandler soDan Liew
that clients can access HandlerInfo nicely.

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
