  12 # There is a problem with the NOP value - it must work for both
  13 # big endian and little endian systems.  Unfortunately there is
  14 # no symmetrical mcore opcode that functions as a noop.  The
  15 # chosen solution is to use "tst r0, r14".  This is a symetrical
  16 # value, and apart from the corruption of the C bit, it has no other
  17 # side effects.  Since the carry bit is never tested without being
  18 # explicitly set first, and since the NOP code is only used as a
  19 # fill value between independantly viable peices of code, it should
  20 # not matter.
