LLVM insertvalue bad optimized?

Question

Should I avoid using the \'insertvalue\' instruction combined with load and store when I emit LLVM code? I always get bad optimized native code when I use it. Look at the fo

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

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

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