gcc与clang:符号剥离 [英] gcc vs. clang: symbol stripping

问题描述

gcc和AMD Open64 opencc都具有-s选项来剥离符号表和重定位信息".到目前为止，我还没有在Clang/LLVM中找到相同的选项.它存在吗?

gcc and AMD Open64 opencc both have a -s option to "strip symbol table and relocation information". So far I haven't been able to find the same option in Clang/LLVM. Does it exist?

推荐答案

您可以使用binutils中的strip实用程序.

You can use a strip utility from binutils.

实际上，llvm-ld具有此选项 http://llvm.org/cmds/llvm -ld.html

Actually, a llvm-ld has this options http://llvm.org/cmds/llvm-ld.html

-strip-all，-s 从可执行文件中剥离所有调试和符号信息 使其更小.

-strip-all, -s Strip all debug and symbol information from the executable to make it smaller.

-strip-debug，-S 将所有调试信息从可执行文件剥离到 缩小它.

-strip-debug, -S Strip all debug information from the executable to make it smaller.

选择也有一些东西:

-strip-debug 此选项导致选择在应用其他模块之前从模块中剥离调试信息 优化.它与-strip本质上相同，但可确保剥离调试 信息首先完成.

-strip-debug This option causes opt to strip debug information from the module before applying other optimizations. It is essentially the same as -strip but it ensures that stripping of debug information is done first.
