KLEE is a symbolic virtual machine that operates on LLVM compiler infrastructure, designed to execute LLVM bitcode modules while supporting symbolic values. Its architecture includes a core symbolic virtual machine engine and a POSIX/Linux emulation layer that utilizes uClibc. The symbolic virtual machine engine is tasked with executing the LLVM bitcode, while the emulation layer allows for parts of the operating system environment to be treated symbolically. Additionally, KLEE features a library that enables the replay of computed inputs on native code, as well as a more intricate system for replaying inputs generated within the POSIX/Linux emulation context. For further details, users can refer to the KLEE webpage.
- KLEE is built on LLVM and supports symbolic execution of bitcode.
- It includes a POSIX/Linux emulation layer for enhanced functionality.
- The system allows for replaying computed inputs on both native code and emulated environments.
- KLEE is useful for testing and analyzing software through symbolic execution.
