Thank you very much for your replay. I tried to do that, however, its print extract-bc: command not found.
I'm trying to extract the bc from SPEC cpu2006 Integer benchmarks. So I did the following. 1. sudo apt install wllvm 2. LLVM_COMPILER=clang CC=wllvm make --> here I use clang version 3.4 and I just write wllvm without a path. 3. Then, it generate the .o files and an executable program(mcf) 4. extract-bc mcf Thank you Nora On 4 July 2017 at 03:04, asantosa1...@gmail.com <asantosa1...@gmail.com> wrote: > I suppose what you want is to produce a bitcode for running with KLEE.
