Perhaps I am missing something, but I don't know of any hardware that would
react differently to this two-instruction sequence:
movl i, %eax
cmpl $1, %eax
than it would to the following single instruction:
cmpl $1, j
Either way, there is a single memory reference, and for all hardware I know of,
it looks the same to both memory and external devices.
