[llvm-dev] Not to consolidate two structs with the same data types (but different names) in configure/make tool chain

I don't follow the above link. Could you help explain what it means?

If directly compile .c to .ll can preserve the original struct
information even they are essentially the same, why flto can not? It
seems to me that there must be a way to preserve such info if flto is
used.
