            Bug ID: 52067
           Summary: Failure to compile __builtin_bcopy
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P

#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
