# 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.
