I feel like I have an even stronger “claim”: independent of any
OS/architecture, unless you are developing a freestanding libc for an
embedded device, you will need this at some point and you cannot borrow
them from another source (which has long been the point of contention about
adding these files to the compiler-rt project - they are tied entirely to
the libc implementation). As a result, the fact that they will exist is
not important to the discussion, it is a given and an implementation detail
of the runtime.
