[PATCH] D86993: Document Clang's expectations of the C standard library.

[Stephen Peckham via Phabricator via cfe-commits]

stephenpeckham added a comment.

Is memmove() expected to perform a lot worse than memcpy()?  Why not just use memmove() all the time.  In some library implementations, memcpy() and memmove() are the same function.
