Obfuscator-LLVM
Obfuscator-LLVM is a free, open-source LLVM fork for Linux that applies obfuscation while software is compiled. It is intended to make programs harder to reverse engineer or modify. Listed passes include instruction substitution, bogus control flow, and control-flow flattening, with function annotations also available. Its intermediate-representation approach covers languages supported by LLVM, including C, C++, Objective-C, Ada, and Fortran. Listed targets include x86, x86-64, PowerPC, ARM, Thumb, SPARC, Alpha, CellSPU, MIPS, MSP430, SystemZ, and XCore. Installation involves cloning the source repository, then building with CMake and make; binaries are placed in build/bin. The guide describes compiler use through Clang, autotools, and a custom Xcode plugin. The latest official non-development branch is llvm-4.0, based on LLVM 4.0.1. The project says obfuscated code can be slower and larger, and describes itself as an advanced prototype needing more testing before production use.
