It's been a few years since I've seen clang/llvm fail to elide a memcpy used in place of type punning (it's an idiom that I use very frequently as a library writer, and care a lot about). If you have examples of cases where llvm fails to do this optimization, please file a bug report and I will be delighted to lean on the right folks to get it fixed. You shouldn't need to work around it.
