It doesn't need to eat opcode space if you only support one data type,
64-bit ints, and one address mode, [register].
Other address modes can be calculated using LEA.
Since these are rare instructions to solve a particular problem,
they won't be used that often, so a few extra instructions shouldn't matter.
You lost me here. Do you mean that a load with address mode
[register] is considered to be a non-address load and not followed by
the data-dependent prefetcher? So how would an address load be
encoded if the natural expression would be [register]?
