내가 컴파일하고 내 프로그램을 연결하고 난 다음과 같이 구축이다 ELF32 리틀 엔디안의 형식 거지 :objcopy 매개 변수 --strip-all이 제거하는 ELF 형식의 부분은 무엇입니까?

그런 다음 내가 진으로 내 형식을 변경하려면 아래 명령을 사용해야합니다. 그것이 제가들은 바입니다. 하지만 누구나 ELF32 형식의 어떤 부분을 정확하게 "--strip-all"매개 변수를 제거하고 ELF32 형식과 다른 이진 형식을 어떻게 사용하는지 알 수 있습니까?
arm-none-eabi-objcopy -I elf32-littlearm -O binary --strip-all --verbose foo1 foo2
위의 ELF32 형식 세부 정보를 포함하여 (가능한 경우) 색을 제거 할 수 있습니다.
대단히 감사합니다.
