有没有人有龙芯扩展指令集的详细描述？

黑洞引擎

想写个汇编器来玩玩，目前只弄了MIPS32 R2的，想把龙芯扩展指令加进去，论坛里有人有吗？
源码贴上，欢迎有兴趣的小伙伴一起学习改进！

程序怎麼玩

make之后得到zhizhu主程序
然后就可以按照下面命令格式翻译汇编文件
./zhizhu -o test test.S
只支持mips文档里（mips32 r2）的指令和格式

報錯

1. $ Diligent\ Spider/zhizhu -o first first.s
   
2. 文件：first.s 第1行 错误码：-1  无法识别的命令！
   
3. .text

复制代码

1.                 .text
   
2.                 .global main
   
3.                 .ent main
   
4. main:                nop
   
5.                 li $v0, 8
   
6.                 jr $ra
   
7.                 .end main

目前只支持mips32 r2的指令格式，具体如下表
而且只实现单条指令的翻译，系统启动码跟接口都没有呢
