--- Comment #4 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
btw jacob the strategy for this one - shift-and-add - is to include
*both* shift-and-add *and* the alternatives (the LD-ST-indexed-shifted
group) and let the OPF ISA WG evaluate which is better.

they might actually decide LD-ST-indexed-shifted is better, we just
never know.  given that both ARM and x86 have them, it's not actually
as hard a sell as it might sound even though it's 37 (!) instructions
(excluding ld-st-indexed-shifted-postincrement)
