Extended Description

#include <stddef.h>

void f(const void *s, void *d, size_t n)
{
    __builtin_bcopy((void *)s, d, n);
}

Trying to compile this with Clang results in this error:

<source>:5:5: error: cannot compile this builtin function yet
    __builtin_bcopy((void *)s, d, n);
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I would assume implementing this is as simple as having it do __builtin_memmove(d, s, n), so it seems odd that this isn't implemented

PS: Also, __builtin_bcopy seems to have an incorrect prototype, which is why the cast is there.
