## Description

Retdec is an LLVM-based machine code decompiler and static binary analysis tool designed for binary reverse engineering. It translates binary executable code into high-level representations to facilitate the reconstruction of program logic from compiled machine code.

The system utilizes a retargetable frontend architecture and a multi-stage lifting pipeline to convert raw bytes into a common intermediate language. It differentiates custom program logic from known library code through signature-based identification and provides utilities for binary symbol demangling to restore human-readable names.

The toolkit covers a broad range of static analysis capabilities, including the reconstruction of high-level functions, types, and class hierarchies. It also provides visualization tools to generate call graphs and control-flow diagrams to map the execution structure of decompiled binaries.
