Sort of keep track of registers and register classes. Start walking the
...
generated instruction tree --- holy cow, they look like instructions!

Stupid stringlist is stupid. Use a proper data structure, properly abstracted
...
out (so other things can use it).

Lots of exploratory new grammar for instruction definitions and string and
...
fragment emission (none of which is hooked up to anything yet).

Massive grammar overhaul and refactor. Hacked in support for predicates, where
...
instructions can be turned on and off based on their parameters. New lexer
using a lexer. Now quite a lot of the way towards being a real instruction
selector.
