All test failures seem to involve LTO. I suspect that the __rdl_* symbols were internalized by LTO and thus can't be used by the linker to resolve the weak aliases for __rust_*.

@bjorn3
Maybe /alternatename isn't necessary after all?

And the weak symbol problem was caused by /export not being in an object file?
