Update.
2000-12-27 Ulrich Drepper <drepper@redhat.com> * sysdeps/alpha/alphaev6/memcpy.S: Don't go through unrolled loop if we would go through it only once. Patch by Rick Gorton <rick.gorton@api-networks.com>. * sysdeps/alpha/alphaev67/strncat.S: Fix handling of numeric parameter. Patch by Richard Henderson <rth@redhat.com>. 2000-12-27 Jakub Jelinek <jakub@redhat.com> * malloc/malloc.c (memmove): Add prototypes. (MALLOC_MEMMOVE): Define. (chunk_realloc): Use it instead of MALLOC_COPY if source and destination might overlap.
