I have this simple code:
```c
#include <stdlib.h>
void foo()
{
int a = 1, b = 2;
}
int main()
{
atexit(foo);
return 0;
}
```
And I compiled with
```bash
clang t.c
```
then the output of comment in `<atexit>` with `llvm-objdump -D` and `objdump -D` below are different:
`llvm-objdump -D` :
```
0000000000001170 <atexit>:
1170: f3 0f 1e fa endbr64
1174: 48 8b 15 8d 2e 00 00 movq 0x2e8d(%rip), %rdx # 0x4008 <__dso_handle>
117b: 31 f6 xorl %esi, %esi
117d: ff 25 4d 2e 00 00 jmpq *0x2e4d(%rip) # 0x3fd0 <__libc_start_main@GLIBC_2.34+0x3fd0>
```
`objdump -D` :
```
0000000000001170 <atexit>:
1170: f3 0f 1e fa endbr64
1174: 48 8b 15 8d 2e 00 00 mov 0x2e8d(%rip),%rdx # 4008 <__dso_handle>
117b: 31 f6 xor %esi,%esi
117d: ff 25 4d 2e 00 00 jmp *0x2e4d(%rip) # 3fd0 <__cxa_atexit@GLIBC_2.2.5>
```
