o-llvm (based on llvm3.4) emit obfuscated code

Question

I'm learning how to use o-llvm based on llvm 3.4.

I have a really simple c file, named "Example.c" that I'm obfuscating and compiling.

clang -mllvm -sub Example.c 

Is there a way to emit the obfuscated code as a .c file??

Answer 1

LLVM Obfuscation happens after the C code has been transformed to LLVM IR. There is not really a good way to convert IR directly back into C code either. You can have o-llvm output the obfuscated code as IR though by using the command line arguments
