[AI summary] The text provides an in-depth exploration of various x86-64 instruction set architectures, focusing on arithmetic operations (ADD, SUB, MUL, SMUL, DIV, SDIV), logical operations (AND, OR, XOR, NOT), and control flow instructions. It details the implementation of these instructions in the QBX virtual machine, emphasizing how they emulate real x86-64 instructions while managing the flags register and handling different operand sizes (8-bit and 16-bit). The text also discusses the nuances of flag handling, register operations, and macro-based code generation to streamline instruction implementation. |
