| # 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. |
