llvm dev - Mar 2018 - [LLD] Mixing bitcode and native code

When having a project that's partially bitcode and partially native code,
should lld allow linking a native .o to a bitcode .o?

specifically in my case, I've got an stdcall function in bitcode, called by
native code, but it can't find the symbol (bitcode has it
unmangled, native code with _ and @20)

When having thinlto enabled in both ends the same thing happens (but bitcode on
both ends works fine)

Mixing native and bitcode files should just work, and that happens all the
time, as most programs need at least crt.o (which is a precompiled native
object file containing startup code).

Could you elaborate the issue a bit? It might be a bug in lld.
