首先，请注意，llc不会进行任何IR级优化.因此，您应该运行opt来运行IR级优化程序集.

First, note that llc does not do any IR-level optimizations. So, you should run opt to run the set of IR-level optimizers.

但是，opt对此无济于事.我希望标准的IR级优化程序可以将这些东西规范化为gep.

However, opt does not help in this. I'd expect that standard IR-level optimizers canonicalize the stuff into gep somehow.

请提交LLVM PR，这似乎错过了优化！

Please file a LLVM PR, this looks like a missed optimization!
