I remember seeing some assembly that had the following sequence in the
middle thereof (not for gcc but you can probably decode it):
LOCK
SEG ES
MOV DI,DI
The first time I read through that, I wondered what on earth it was
supposed to do, and only later did I realise it was effectively a
rather verbose NOP instruction...
