I would at least hope that if the issue is in ld64 itself and not LTO, that we are making sure that lld is not repeating the same choices here. FWIW, we have our own custom linker and LTO builds easily chews through memory into this peak size realm, way beyond what a non-LTO link would do.

Yes, absolutely. There are quite a few different aspects of improving LTO scalability. Most of them are not specific to a particular linker. This is just one of them. If you guys want to tackle other problems, feel free.
