Hi - I'm not sure if this sounds correct to me. Can you more concretely explain what you are trying to fix? A lot of instructions do get split up into multiple micro-ops. (Not all of them thought, and that isn't well modelled in llvm - there is no way to specify the individual operations and dependencies between them).
