The best resource to use when trying to figure out which byte correlates to which instruction is the X86 Opcode and Instruction Reference by MazeGen. Looking at the page, we see two sets of instructions: one byte instructions, or two byte instructions starting with the instruction expansion byte...

x86 操作码结构和指令表
Opcode suffixes of `b', `w', and `l' specify byte (8-bit), word (16-bit), and long (32-bit) memory references. //Intel 语法实现操作数的size通过,operand的前缀,如,byte ptr (byte, 8), word ptr(word,16), dword ptr(double word, 32) ...
A.2 Opcode描述此附录包含NASM对每个指令生成的opcodes. 16进制数,例如3F,代表包含此数字的固定字节。 16进制数,后面有+r, 例如3F+r, 代表指令的一个operands是寄存器,并且这个寄存器的“寄存器值”需要和这个1…
r/m field 范围0-7, 在最低3bit, spare field 在中间(bit3-5)。The spare field is not relevant to the effective address being encoded, and either contains an extension to the instructionopcodeor the register value of another operand.

(11)空白:直接类型说明,为0,与通用的一样,不过后面的opcode没有name (12)异常代码:例如UD0, 太少不放进去结构体了 加粗的都是关键,其他的只是说明注解。 那么应该怎么使用 OPCODE TABLES建议大家去看Intel文档的Volume 2 (2A, 2B, 2C & 2D):Instr...
