Author: mjg Date: Sat Oct 13 21:17:28 2018 New Revision: 339348 URL: https://svnweb.freebsd.org/changeset/base/339348 Log: amd64: convert libc bcopy to a C func to avoid future bloat The function is of limited use and is an almost a direct clone of memmove/memcpy (with arguments swapped). Introduction of ERMS variants of string routines would mean avoidable growth of libc. bcopy will get redefined to a __builtin_memmove later on with this symbol only left for compatibility.
