[llvm-objdump] llvm-objdump cannot disassemble __stack_chk_* symbol

[CoTinker]

demo.c

#include <string.h>

void func() {
	char c = 'b';
	char str1[1];
	memset(str1, c, 1);
}

compile command

% clang demo.c -c -o demo.o -fstack-protector-strong
% objdump -d demo.o | grep __stack_chk*
   c:   90000008        adrp    x8, 0 <__stack_chk_guard>
  30:   90000008        adrp    x8, 0 <__stack_chk_guard>
  48:   94000000        bl      0 <__stack_chk_fail>
-------------------------------------------------------
% llvm-objdump -d demo.o | grep __stack_chk*
NULL

we can see that binutils objdump can get __stack_chk* symbol, while llvm-objdump can not.

% llvm-objdump -d demo.o | grep __stack_chk*
NULL

we can see that binutils `objdump `can get __stack_chk* symbol, while `llvm-objdump` can not.
