--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Yeah, we do remove unused (as in unused from the source) memcpy implementations
early but then introduce uses ourselves.
I suppose we should avoid doing that with -ffreestanding, thus basically add
the used attribute on a select number of definitions automatically with this
option.
I wonder for example whether a static definition of memcpy would need to be
preserved since I think this isn't really special to LTO.
Joseph? Honza?
