I noticed this when looking into Ganapat's fix to arm-cs-trace-disasm.py. I assumed that seeing this in the output was a bug and went to investigate why it happened in some cases and not others.
It turned out to not actually be a bug, but I think it doesn't look right. In the end this change doesn't really accomplish anything and I'm not sure if it's worth putting it in or not?
Maybe it will save someone doing the same thing as me, or maybe it will actually break something if someones script is looking for 0xdeadbeef?
