>From what I understand, the way LTO works on LLD COFF and ELF is that the appropriate LLVM libraries are just (statically) linked into LLD itself, so there's no concept of an LTO library. I assume that LTO support in LLD Mach-O will work the same way when it's implemented, so the option should never be needed there either. I think it makes more sense to change the clang driver to not pass the option to LLD, but I'm adding @pcc to confirm that my understanding of LTO is correct.
