나는 노력하고있다GCC 119~에서GCC 컴파일 팜. GCC119는 빅엔디안 AIX 머신입니다. Power8을 사용하는 AES 암호화로 인해 성능이 저하되는 이유를 알아내려고 합니다.
구성이 좀 표준적이지 않은 것 같은데 AIX 관리자들이 잘 관리하고 있습니다. 디스어셈블러는 에 있습니다 /opt/IBM/xlc/13.1.3/exe/dis.
디스어셈블러를 실행하거나 도움을 얻으려고 할 때:
-bash-4.3$ dis
-bash: dis: command not found
-bash-4.3$ /opt/IBM/xlc/13.1.3/exe/dis rijndael-simd.o
-bash-4.3$ /opt/IBM/xlc/13.1.3/exe/dis -d rijndael-simd.o
-bash-4.3$ /opt/IBM/xlc/13.1.3/exe/dis -help
-bash-4.3$ /opt/IBM/xlc/13.1.3/exe/dis /help
-bash-4.3$ man dis
Manual entry for dis not found or not installed.
-bash-4.3$ man -k disassemble
man: 0703-310 file man not found.
Create the whatis database using the <catman -w> command
온라인 검색은 유용한 결과를 반환하지 않습니다. 예를 들어,IBM AIX에서 objdump와 동등한 명령은 무엇입니까디스어셈블러가 무엇인지 알려주지 dis만 사용법은 알려주지 않습니다.
머신에는 Binutils가 있지만 objdump빅엔디안 AIX 개체 파일을 잘 분해하지 못합니다. IBM의 제품도 참조하세요.객체 파일 탐색을 위한 UNIX 도구.
IBM을 사용하여 dis개체 파일을 분해하는 방법은 무엇입니까? 특히 명령어 니모닉과 분해된 C++ 이름을 보고 싶습니다.
아래는 에서 분해한 내용입니다 objdump. 아쉬운 점이 많습니다. vcipher, vcipherlast vncipher및 와 같은 지침이 표시되어야 합니다 vncipherlast.
