David Given 4a3a9a98dc It doesn't really make a lot of sense to have BURG nonterminal names different
to register classes, so combine them. Refactor the map code.

David Given b32883b013 More properly keep track of register classes. 2016-09-29 22:32:43 +02:00
David Given 39aa672422 Sort of keep track of registers and register classes. Start walking the
generated instruction tree --- holy cow, they look like instructions!

David Given bcc74ba18d Stupid stringlist is stupid. Use a proper data structure, properly abstracted
out (so other things can use it).

David Given 9f78e0b36b Rethink the way patterns are mapped to rules; generate emitters (probably
badly).

David Given 7c028bdd45 We now record the code fragments to be emitted by each rule. 2016-09-25 00:21:46 +02:00
David Given 629e0ddfc6 Some instruction selection is now happening. 2016-09-24 22:46:08 +02:00
David Given c8fcbe282a More grammar changes. 2016-09-24 19:03:55 +02:00
David Given 2acc4ed29d IR codes are now owned by mcgg; ir terminals are inserted into the table during
compilation (so you can refer to them).

David Given 960259f0b0 Add support for labelled tree nodes. 2016-09-24 12:11:30 +02:00
David Given 4546dd5f22 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.
