  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.
MOV----> move
MOVSX---->extended move with sign data
MOVZX---->extended move with zero data
PUSH---->push
POP---->pop
PUSHA---->push all
POPA---->pop all
PUSHAD---->push all data
POPAD---->pop all data
BSWAP---->byte swap
XCHG---->exchange
CMPXCHG---->compare and change
XADD---->exchange and add
XLAT---->translate
2.输入输出端口传送指令.
IN---->input
OUT---->output
3.目的地址传送指令.
LEA---->load effective address
LDS---->load DS
LES---->load ES
LFS---->load FS
LGS---->load GS
LSS---->load SS
4.标志传送指令.
LAHF---->load AH from flag
SAHF---->save AH to flag
PUSHF---->push flag
POPF---->pop flag
PUSHD---->push dflag
POPD---->pop dflag

二、算术运算指令
ADD---->add
ADC---->add with carry
INC---->increase 1
AAA---->ascii add with adjust
DAA---->decimal add with adjust
SUB---->substract
SBB---->substract with borrow
DEC---->decrease 1
NEC---->negative
CMP---->compare
AAS---->ascii adjust on substract
DAS---->decimal adjust on substract
MUL---->multiplication
IMUL---->integer multiplication
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
———————————————————————————————————————

TEST---->test
SHL---->shift left
SAL---->arithmatic shift left
SHR---->shift right

RCL---->rotate left with carry
RCR---->rotate right with carry

四、串指令
———————————————————————————————————————
MOVS---->move string

STOS---->store string
REP---->repeat
REPE---->repeat when equal
REPZ---->repeat when zero flag
REPNE---->repeat when not equal
REPNZ---->repeat when zero flag

REPNC---->repeat when not carry flag

五、程序转移指令
———————————————————————————————————————
1>无条件转移指令(长转移)
JMP---->jump

JNA---->jump when not above
JG---->jump when greater
JNLE---->jump when not less or equal
JGE---->jump when greater or equal
JNL---->jump when not less
JL---->jump when less
JNGE---->jump when not greater or equal
JLE---->jump when less or equal
JNG---->jump when not greater
JE---->jump when equal
JZ---->jump when has zero flag
JNE---->jump when not equal
JNZ---->jump when not has zero flag
JC---->jump when has carry flag
JNC---->jump when not has carry flag
JNO---->jump when not has overflow flag
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
JS---->jump when has sign flag
3>循环控制指令(短转移)
LOOP---->loop
LOOPE---->loop equal
LOOPZ---->loop zero
LOOPNE---->loop not equal
LOOPNZ---->loop not zero
JCXZ---->jump when CX is zero
