riscv 汇编与反汇编

为了riscv指令集，我们需要汇编与反汇编工具来分析指令格式。

可以用下面的两个工具来汇编和反汇编，下载链接：https://pan.baidu.com/s/1eUbBlVc

riscv-none-embed-as.exe -c mm.s -o mm.o --march=rv32g

mm.s

addi x10, x6, 20
addi x11, x6, 20
addi x10, x6, 20
addi x10, x6, 20
beq  x10,x11,label
addi x12, x6, 20
addi x12, x6, 20
label:
addi x12, x6, 20
addi x12, x6, 20
addi x12, x6, 20

riscv-none-embed-objdump.exe -d mm.o -M no-aliases,numeric

反汇编后的代码为：

mm.o:     file format elf32-littleriscv
