"libcpu" is an open source library that emulates several CPU architectures, allowing itself to be used as the CPU core for different kinds of emulator projects. It uses its own frontends for the different CPU types, and uses LLVM for the backend. libcpu is supposed to be able to do user mode and system emulation, and dynamic as well as static recompilation.


CMake version 2.8 or higher is required.

On Ubuntu:

sudo apt-get install flex bison libreadline-dev

On Fedora:

sudo yum install flex bison readline-devel
