In addition, the macros `INSTPAT_START` and `INSTPAT_END` are defined in `nemu/include/cpu/decode.h`. `INSTPAT` uses two other macros, `INSTPAT_INST` and `INSTPAT_MATCH`, which are defined in `nemu/src/isa/$ISA/inst.c`. After expanding the above code with macros and simply organizing the code, you will end up with.
```c
{ const void ** __instpat_end = &&__instpat_end_;
{ const void * __instpat_end = &&__instpat_end_;

uint64_t key, mask, shift;

命令中的`./`是不能少的, 点代表了当前目录, 而`./hello`则表示当前目录下的`hello`文件.
与Windows不同, Linux系统默认情况下并不查找当前目录,
这是因为Linux下有大量的标准工具(如`test`等), 很容易与用户自己编写的程序重名, 不搜索当前目录消除了命令访问的歧义.
