实用汇编指令

Posted 2023-04-08

参考技术A 1.跳转指令
B 无条件跳转
BL 带链接的无条件跳转
BX 带状态切换的无条件跳转 根据目标地址最低位切换状态（arm/thumb）
BLX 带链接和状态切换的无条件跳转
B loc_地址
BEQ,BNE

2.存储器与寄存器交互数据指令 核心

3.数据传送指令
MOV：将立即数或寄存器的数据传送到目标寄存器 ←
MOV R0, #8 R0=8

4.数据算术运算指令
←
ADD,SUB,MUL,DIV
有符号，无符号运算；带进位运算

5.数据逻辑运算指令
与：AND
或：ORR
异或：EOR
移位：实质是乘，除，类似于小数点移位，但相反。小数点左移，数变小；右移变大。
但逻辑移位，左移变大，右移变小，且按2的倍数进行，因为是2进制。
LSL：逻辑左移←
LSR：逻辑右移←

6.比较指令
CMP：比较
CMP R0 #0 R0寄存器中的值与0比较
标志位：如z位，这个都可以在动态调试时，寄存器窗口看到

7.其他指令
协处理器指令：SWT （切换用户模式）
伪指令：DCB

8.寄存器寻址方式
立即寻址：MOV R0,#1234 R0=0X1234
寄存器寻址：MOV R0,R1 R0=R1
寄存器移位寻址：MOV R0,R1,LSL #2 R0=R1*4
寄存器间接寻址：LDR R0,[R1] 将R1寄存器中的值作为地址，取出地址中的值赋予R0
寄存器间接基址偏移寻址：LDR R0,[R1，#-4]将R1寄存器的值-0x4的值作为地址，取出地址中的值给R0

对int a=0;这一句简单高级语言的汇编理解，首先会开辟一个内存存储单元，然后把0x0这个数放入R0寄存器，
然后再把R0寄存器的数据放入内存存储单元。所以：
MOV R0,#0
STR R0，[R11,#0x14+var_20]

汇编指令手册

请问哪位朋友有汇编指令手册
最好哪些指令有英文全称注释
这样好理解些
比如MOV是move
JNZ是jump if not zero

lad是load
