[PATCH] D86025: [CodeGen] Respect libfunc availability when lowering intrinsic memcpy

[Amara Emerson via Phabricator via llvm-commits]

aemerson added a comment.

If we can’t lower it into a libcall, what *can* we do with it beyond optimizing into an unrolled in-line sequence? Just generate a whole memcpy implementation inline?
