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.
