> Note that multi-arch builds are an open question (just like multi-arch .pcm files are I believe); the format could support it as two reports on provides/reqs, but the merged object file complicates things.

BTW, we decide to forbid multiple-arch .pcm files in https://reviews.llvm.org/D137058 now since we don't know how to handle it properly.
