 * byteswap.il -- definitions for .inline functions for little-endian loads.
 *
 * right now, this file is only used on UltraSPARC architectures,
 * which have a special address space identifier for loading 32 and 16 bit
 * integers in little-endian byte order.
 *
 * note: apparently these files are not preprocessed, so we cannot
 *       use `ASI_PL'.
 *
 * This file and common/crypto/md5/md5_byteswap.h implement the
 * same thing and must be changed together.
