我正在尝试海湾合作委员会119来自GCC 编译农场。 GCC119 是一台大端 AIX 机器。我正在尝试找出使用 Power8 加密的 AES 性能缓慢的原因。
我认为配置有点不标准，但是 AIX 管理员维护得很好。反汇编程序位于/opt/IBM/xlc/13.1.3/exe/dis.
当我尝试运行反汇编程序或获取帮助时：
-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
在线搜索不会返回有用的结果。例如，IBM AIX 中 objdump 的等效命令是什么告诉我反汇编程序是dis但它没有说明如何使用它。
该机器有 Binutils objdump，但它不能很好地反汇编大端 AIX 目标文件。另请参阅 IBM 的用于探索目标文件的 UNIX 工具。
如何使用 IBMdis来反汇编目标文件？我特别想查看指令助记符和分解后的 C++ 名称。
下面是来自 的反汇编objdump。它还有很多不足之处。我应该看到诸如vcipher、vcipherlast vncipher和 之类的说明vncipherlast。
-bash-4.3$ /opt/cfarm/bi
binutils-latest/ bison-latest/
-bash-4.3$ /opt/cfarm/binutils-latest/bin/objdump --disassemble rijndael-simd.o
