# There is a problem with the NOP value - it must work for both

# big endian and little endian systems.  Unfortunately there is

# no symmetrical mcore opcode that functions as a noop.  The

# chosen solution is to use "tst r0, r14".  This is a symetrical

# value, and apart from the corruption of the C bit, it has no other

# side effects.  Since the carry bit is never tested without being

# explicitly set first, and since the NOP code is only used as a

# fill value between independantly viable peices of code, it should

# not matter.
