Zydis is an x86 and x86-64 binary analysis library that provides a framework for decoding machine code and inspecting the technical attributes of processor instructions. It functions as an instruction disassembler that translates binary data into structured instruction metadata and human-readable assembly. The project includes a machine code encoder for converting assembly instructions and operands back into their binary representations. It also provides an assembly syntax formatter to transform decoded instruction structures into assembly text strings using configurable syntax styles. The l
Implements logic to identify processor extensions and addressing modes by analyzing x86 instruction prefixes.
