只需告诉NASM使用-g编译源代码以添加调试符号：

nasm -g -f elf64 -o hello.o hello.asm
gcc -m64 hello.o -o hello -no-pie
gdb hello

打开GDB后，您可以使用list显示源代码：

Reading symbols from hello...
(gdb) list
1           extern  printf          ; the C function, to be called
2   
3           section .data           ; Data section, initialized variables
4   msg:    db "Hello world", 0     ; C string needs 0
5   fmt:    db "%s", 10, 0          ; The printf format, "\n",'0'
6   
7           section .text           ; Code section.
8   
9           global main             ; the standard gcc entry point
10  main:                           ; the program label for the entry point

下面是一个source code示例：

; Declare needed C  functions
        extern  printf          ; the C function, to be called

        section .data           ; Data section, initialized variables
msg:    db "Hello world", 0     ; C string needs 0
fmt:    db "%s", 10, 0          ; The printf format, "\n",'0'

        section .text           ; Code section.

        global main             ; the standard gcc entry point
main:                           ; the program label for the entry point
        push    rbp             ; set up stack frame, must be aligned
    
        mov rdi,fmt
        mov rsi,msg
        mov rax,0               ; or can be  xor  rax,rax
        call    printf          ; Call C function

        pop     rbp             ; restore stack 

        mov rax,0               ; normal, no error, return value
        ret                     ; return
