Author: Karel Lejska a.k.a. MazeGen. This reference is intended to be precise opcode and instruction set reference ( including x86-64 ). Its principal aim is exact definition of instruction parameters and attributes. The reference is primarily based on Intel manuals as Intel is the originator of x86 architecture. Additionally, it describes undocumented instructions as well. On appropriate places, it gives a notice if an opcode act differently on AMD architecture. Support for Cyrix, NexGen etc. specific instructions is not scheduled at all.
