4b4f92780e Shuffle extension word order. 
The primary objective here is simplifying index calculation, but as per the note it does also potentially open up options with regard to packing in the future.

dc1d1f132e Add one more address size modifier test. 2022-03-11 13:01:02 -05:00
Thomas Harte
9b4048ec6e The address size modifier doesn't seem to affect far address sizes. 
It's meant to affect only instructions with operands that reside in memory, I think. So probably only ::DirectAddress in my nomenclature. More research to do.
