This is the "library" that only contains the minikernel and the required build-system for SystemC in LLVM Bitcode. For some experiments/examples, see symsysc-experiments
clang, llvm-link, libc++ (get by installing g++) or libcxx-devel, also libc++abi-dev.
Optional, but nice: wllvm (pip install wllvm)
If klee not available, build it yourself (warn: Will take some time)
