actual implementations of this function do not incur the overhead or double copying or extra memory. A common approach (glibc and bsd libc) is to copy bytes forwards from the beginning of the buffer if the destination starts before the source, and backwards from the end otherwise, with a fa...
The LLVM passes confirm that LLVM continues to consider good a memcpy until code is emitted. I also believe that this invalidates your claim that the check for src != dst needs to be made in the source code, otherwise goods body of ptr[dst] = ptr[src] would be UB! surely clang ...
