[PATCH] D79279: Add overloaded versions of builtin mem* functions

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

Is there a need for an atomic memcpy at all?  Why is it useful to allow this operation to take on "atomic" semantics — which aren't actually atomic because the loads and stores to elements are torn — with hardcoded memory ordering and somewhat arbitrary rules about what the atomic size is?
