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.
2019-05-28Implement handling of the llvm.fabs intrinsicFelix Rath
2019-04-04some minor refactoringsFrank Busse
2019-04-04Clean klee-stats, StatsTracker and cmakeTimotej Kapus
2019-04-04Change the .stats format into sqlite3Timotej Kapus
Improves querying of the .stats file, reduces its size, speeds up reads and writes and has better defined fail behaviour.

2019-03-19Fix representation of ReadExpr of equivalent arraysMartin Nowack
ObjectStates can be shared between multiple states. A read expression of a symbolic object can be represented differently depending on previous read expression on the same object. If the read expression uses a symbolic index, all pending updates will become entries in the update list of the object state. If the same object state is read again, with a concrete index, the latest update list item will be referenced, even though it might contain more recent but non-essential updates. If, instead, a concrete read will be executed first, it does not contain the non-essential updates. For both executions, the ReadExpr with a constant index will have two different representations, which is not intented. This patch makes sure, we do not include more recent, non-essential updates for concrete reads. Fixes #921
2019-03-18Disable optimisation for functions that contain KLEE callsMartin Nowack
Compilers are allowed to hoist function calls and do GVE. This is currently done even without `--optimization` enabled. This is unfortunate in the context of KLEE function calls that might depend on specific code position without direct control flow dependencies. In such cases, function calls can be hoisted. To circumvent this, disallow to optimise functions that contain such calls by default. This might reduce optimisation for some functions containing such function calls but still allows it for all others. This patch adds an additional pass, that detects all functions starting with a prefix `klee_` and disable optimisations for functions containing such calls. This is enabled by default but can be disabled by `--klee-call-optimisation=false`.
