NASM：搬迁截断以适应：R_386_PC8对`* UND *”

Question

我下面的代码链接时收到以下错误，但我不明白为什么：

ld -m elf_i386 shell.o -o test 
shell.o: In function `_start': 
shell.asm:(.text+0xbc): relocation truncated to fit: R_386_PC8 against `*UND*' 

代码：

SECTION .text 
global  _start        ;must be declared for linker (ld) 
_start: 
xor eax,eax 
push eax 
push 0x25722424 
push 0x73747670 
      push 0x24777470 
     push 0x75792278

    push esp

       mov edx,edi 
       cld 
     mov ecx,0x80 
      mov ebx,0x41 
       xor eax,eax 
        push eax 
        lodsb 
        xor eax,ebx 
        stosb 
       loop 0xb7 
        push esp 
        pop esi 
int3 

Answer 1

push eax 
michael: 
lodsb 
xor eax,ebx 
stosb 
loop michael 
push esp 
pop esi 
int3 

只需像我在前面的代码中那样使用循环标签即可。我把它叫做迈克尔，但记住你必须先像这样定义迈克尔：然后你可以使用它。
