+# 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.
