11 | 12 | python脚本需从命令行调用，因使用了`prettytable`库以获得更规整的视觉效果，需要首先用pip安装： 13 | 14 | ````shell 15 | pip install prettytable 16 | ```` 17 | 18 | 然后指定python解释器调用该脚本，参数为对`.o`文件使用`objdump -D`命令生成的反汇编文件名，要求使用相对路径（因脚本中会拼接为绝对路径），同一目录下键入文件名即可。命令中`my_objdump.s`为示例的反汇编文件名。 19 | 20 | ```shell 21 | python3 decoder.py my_objdump.s 22 | ``` 23 | 24 | 该脚本使用输出的示例如下： 25 | 26 | ```assembly 27 | Disassembly of section .text: 28 | 29 | 0000000000000000 : 30 | 0: 00050793 mv a5,a0 31 | bit-level representation: 32 | 00000000000001010000011110010011 33 | +--------------+-------+--------+-------+---------+ 34 | | imm[11:0] | rs1 | funct3 | rd | opcode | 35 | +--------------+-------+--------+-------+---------+ 36 | | 000000000000 | 01010 | 000 | 01111 | 0010011 | 37 | +--------------+-------+--------+-------+---------+ 38 | ... 39 | ``` 40 | 41 | 可以在上述命令后添加重定向命令以直接获得完整的文本，如将命令更改为： 42 | 43 | ```shell 44 | python3 decoder.py my_objdump.s > my_decoder.s 45 | ``` 46 | 47 | 此时`my_decoder.s`文件中的文本，即如上述示例，已经插入了机器指令的二进制表示，以及各字段分解的表格。 48 | 49 | --- 50 | 51 | 目前已经支持的指令包括 `RV32I Base Instruction Set`(除去 `FENCE`，`ECALL`，`EBREAK`)，`RV64I Base Instruction Set`和各自的standard extension（可在此表中对照），暂不支持 16 位压缩指令。 52 | 53 | riscv64-linux-gnu-gcc 的 `-c` 指令会默认生成带压缩指令的机器码，可以使用如下编译指令使产生的`test.o`目标模块文件中`.text`代码段中只含32位指令： 54 | 55 | ``` 56 | riscv64-linux-gnu-gcc -c -march=rv64g test.s 57 | ``` 58 | 59 | ## 注意 60 | 61 | + release 中打包了经过编译、开箱即用的软件，如果没有 Qt 环境可以自取。 62 | + 对于`j`或是`li`这样的伪指令，本软件会按照其机器码对应的原指令直接拆分（即`jal`和`addi`） 63 | + 本软件并不能由机器码指令输出对应的汇编指令，这样设计是考虑到 `objdump` 已经完成了这一工作，因此，本软件应配合 `objdump` 使用。 64 | + 软件中 RV32I 和 RV64I 的主要区别在于，在 RV32I 中，`SLLI`，`SRLI`，`SRAI` 的 `shamt` 字段占 5 位，而在 RV64I 中占 6 位。具体数据来自于上面提到的表。 65 | + 如果您发现了错误，请在 Issues 中告知我，十分感谢；也欢迎您提交 pr 来丰富本软件的功能，或使其支持其他指令集。 66 | -------------------------------------------------------------------------------- /decoder.py:
