note

mov dst, src

xchg dst, src ; 交换数据 dst <-> src

push src
pop dst

pushf         ; flag register 数值压栈
popf

add dst, src  ; dst = dst + src  可能影响到 C(carray flag 进位标志)
adc dst, src  ; dst = dst + src + C ; (Add withCarry)带进位加法指令 主要用于多字节运算, 比如 u128 类型的数相加
inc dst       ; dst += 1 不影响 C

sub dst, src  ; dst = dst - src
sbb dst, src  ; dst = dst - src -C ; (SubtractionwithBorrow)进位减法指令
dec dst       ; dst -= 1, decrement <oprand> by 1

neg dst       ; dst = -dst   ; (Negate) 求补指令
cmp dst, src  ; dst - src    ; (Compare)比较指令 用以影响标识位


and dst, src  ; dst = dst&src ; 按 bit 与
test dst, src ; dst&src       ; 不保存结果, 只用来影响标识位
or dst, src
xor dst, src
not dst

Unsigned Multiplicationn

mul <src>

Instruction	Explanation
mul <src> mul <op8> mul <op16> mul <op32> mul <op64>	Multiply A register (al, ax, eax, or rax) times the <src> operand. Byte: *ax = al <src> Word: dx:ax = ax * <src> Double: edx:eax = eax * <src> Quad: rdx:rax = rax * <src> Note, <src**> operand cannot be an immediate
Examples:	mul word [wVar] mul al mul dword [dVar] mul qword [qVar]
