有没有关于优化不会出现在EXE中的DLL的警告？

Question

I am generally familiar with the sorts of optimizations performed by the -O2 or -O3 switches.

I have been bitten a couple of times now by issues that are specific to building a DLL that don't appear in writing a flat executable, so before I start turning on optimizations are there any "gotcha"s that I should be aware of?

EXE中的死代码消除基本上以main作为可达性的单个根开始，但DLL的每个导出函数都是单独的根。
