A small mistake

[miaoxw]

In the section '入门', we have an assembly program hello.asm. It seems that there is a small mistake in the translation of comments:

    ; write(1, message, 13)
    mov     rax, 1                  ; system call 1 is write
    mov     rdi, 1                  ; file handle 1 is stdout
    mov     rsi, message            ; address of string to output
    mov     rdx, 13                 ; number of bytes
    syscall                         ; invoke operating system to do the write

     ; exit(0)
    mov     eax, 60                 ; system call 60 is exit
    xor     rdi, rdi                ; exit code 0
    syscall                         ; invoke operating system to exit

The translation are:

    ; write(1, message, 13)
    mov     rax, 1                  ; 1号系统调用是写操作
    mov     rdi, 1                  ; 1号文件系统调用是标准输出
    mov     rsi, message            ; 输出字符串的地址
    mov     rdx, 13                 ; 字符串的长度
    syscall                         ; 调用系统执行写操作

    ; exit(0)
    mov     eax, 60                 ; 60号系统调用是退出
    xor     rdi, rdi                ; 0号系统调用作为退出
    syscall                         ; 调用系统执行退出

Here are the suggestions:

• Change the comment on line XOR to '0作为程序返回值';
• The term '系统执行' is a little strange. It may be better to replace it with '系统调用'.
