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