optimization - gcc 与 clang : symbol stripping

Question

gcc 和 AMD Open64 opencc 都有一个 -s “剥离符号表和重定位信息”的选项。到目前为止，我还没有在 Clang/LLVM 中找到相同的选项。它存在吗？

Answer 1

您可以使用 strip来自 binutils 的实用程序。

实际上，一个 llvm-ld 有这个选项 http://llvm.org/cmds/llvm-ld.html

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

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

选择也有一些东西:

-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.
