15 /* The following tests optimise behaviour on little-endian
16 machines, where there is no need to reverse the byte order
17 of 32 bit words in the MD5 computation. By default,
18 HIGHFIRST is defined, which indicates we're running on a
19 big-endian (most significant byte first) machine, on which
20 the byteReverse function in md5.c must be invoked. However,
21 byteReverse is coded in such a way that it is an identity
22 function when run on a little-endian machine, so calling it
23 on such a platform causes no harm apart from wasting time.
24 If the platform is known to be little-endian, we speed
25 things up by undefining HIGHFIRST, which defines
26 byteReverse as a null macro. Doing things in this manner
27 insures we work on new platforms regardless of their byte
28 order. */
