【ASM】汇编常用指令

  由于内核代码中经常有汇编指令，于是上网赵了一篇我认为比较好的汇编常用指令的文章，和大家分享一下。
因为他把所有汇编指令的全称都给了出来，这样非常便于我们记忆和理解。

1.通用数据传送指令.

OUT---->output
3.目的地址传送指令.
LEA---->load effective address

AAM---->ascii adjust on multiplication
DIV---->divide
IDIV---->integer divide
AAD---->ascii adjust on divide
CBW---->change byte to word
CWD---->change word to double word
CWDE---->change word to double word with sign to EAX
CDQ---->change double word to quadrate word

三、逻辑运算指令

JNP---->jump when not has parity flag
JPO---->jump when parity flag is odd
JNS---->jump when not has sign flag
JO---->jump when has overflow flag
JP---->jump when has parity flag
JPE---->jump when parity flag is even
