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

Rethink the way patterns are mapped to rules; generate emitters (probably
...
badly).

We now record the code fragments to be emitted by each rule.

Some instruction selection is now happening.

IR codes are now owned by mcgg; ir terminals are inserted into the table during
...
compilation (so you can refer to them).

Change the predicate stuff to use costs instead; now you can use when clauses
...
on leaves. Remove an iburg premature optimisation (required for above).

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.
