>From the Abstract
The new head-and-tails (HAT) format splits each instruction into a
fixed-length head and a variable-length tail, and packs heads and tails
in separate sections within a larger fixed-length instruction bundle.
The paper evaluated 128-bit and 256-bit instruction bundles.
As an idle question, how hard would it be for cgen to support this?
