# commit 759cfef3ac4c07dba1ece0bbc1207e099348816d
# Author: Alan Modra <amodra@gmail.com>
# Date:   Sat Aug 17 18:47:22 2013 +0930
# 
#     PowerPC LE memcpy
#     http://sourceware.org/ml/libc-alpha/2013-08/msg00103.html
#     
#     LIttle-endian support for memcpy.  I spent some time cleaning up the
#     64-bit power7 memcpy, in order to avoid the extra alignment traps
#     power7 takes for little-endian.  It probably would have been better
#     to copy the linux kernel version of memcpy.
#     
#         * sysdeps/powerpc/powerpc32/power4/memcpy.S: Add little endian support.
#         * sysdeps/powerpc/powerpc32/power6/memcpy.S: Likewise.
#         * sysdeps/powerpc/powerpc32/power7/memcpy.S: Likewise.
#         * sysdeps/powerpc/powerpc32/power7/mempcpy.S: Likewise.
#         * sysdeps/powerpc/powerpc64/memcpy.S: Likewise.
#         * sysdeps/powerpc/powerpc64/power4/memcpy.S: Likewise.
#         * sysdeps/powerpc/powerpc64/power6/memcpy.S: Likewise.
#         * sysdeps/powerpc/powerpc64/power7/memcpy.S: Likewise.
#         * sysdeps/powerpc/powerpc64/power7/mempcpy.S: Likewise.  Make better
#         use of regs.  Use power7 mtocrf.  Tidy function tails.
