Boomerang Decompiler is an open source machine code decompiler that converts compiled binary executables back into high-level C source code. The tool supports multiple processor architectures including x86 (IA-32), PowerPC (PPC), and ST20. It can process various executable file formats such as ELF, PE, DOS MZ, DOS/4GW LE, and Mach-O. The decompiler analyzes binary machine code and reconstructs the original program logic, control flow, and data structures to generate readable C code output. This reverse engineering capability assists security researchers and analysts in understanding the functionality of compiled programs without access to original source code. Boomerang requires a 64-bit operating system and depends on several development tools including a C++17 compiler, CMake, Qt5, Capstone disassembly framework, GNU bison, and GNU flex. The project is distributed under a BSD license and provides both pre-compiled packages and source code for building from the development branch. The tool includes optional components for documentation generation, regression testing, and build optimization through CCache integration.
