|
|
KLEE is a symbolic virtual machine built on top of the LLVM compiler
|
|
infrastructure. Currently, there are two primary components:
|
|
|
|
1. The core symbolic virtual machine engine; this is responsible for
|
|
executing LLVM bitcode modules with support for symbolic values. This
|
|
is comprised of the code in lib/.
|
|
|
|
2. A POSIX/Linux emulation layer oriented towards supporting uClibc, with
|
|
additional support for making parts of the operating system environment
|
|
symbolic.
|
|
|
|
Additionally, there is a simple library for replaying computed inputs on
|
|
native code (for closed programs). There is also a more complicated
|
|
infrastructure for replaying the inputs generated for the POSIX/Linux
|
|
emulation layer, which handles running native programs in an environment
|
|
that matches a computed test input, including setting up files, pipes,
|
|
environment variables, and passing command line arguments.
