The record

What it does: RetDec is a retargetable machine-code decompiler based on LLVM.
Supported formats: It supports ELF, PE, Mach-O, COFF, AR archives, Intel HEX, and raw machine code.
Supported architectures: It supports 32-bit Intel x86, ARM, MIPS, PIC32, and PowerPC, plus 64-bit x86-64 and ARM64 (AArch64).
Analysis features: Features include static executable analysis, compiler and packer detection, and loading and instruction decoding.
Debug data: It extracts and uses DWARF and PDB debugging information.
C++ analysis: It detects and reconstructs C++ class hierarchies using RTTI and vtables, and demangles GCC, MSVC, and Borland symbols.
Output: It reconstructs functions, types, and high-level constructs and outputs C or a Python-like language.
Graphs and disassembly: It includes an integrated disassembler and can generate call graphs, control-flow graphs, and statistics.
Integrations: Related repositories provide plugins that embed RetDec into IDA and Radare2.
Deployment: RetDec can be downloaded as a pre-built package, built from source, or run in a Docker container.
Platforms and storage: The project lists Windows 7 or later, Linux, macOS, and experimental FreeBSD support, and says an installation needs about 5 to 6 GB of free disk space.
License: The project states that it is licensed under the MIT license and also incorporates a modified PeLib library under the zlib/libpng license for its original sources.
Security: The repository links to a security policy, but its policy page displayed a loading error when opened.
Support and maintenance: The repository says the project is in limited maintenance mode: issues may receive responses with delays up to one quarter, and development is very limited.
