// Klee Symbolic Virtual Machine

//===----------------------------------------------------------------------===//

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.
