David Given	a8ee82d197	Stop passing proc around, and use a global instead --- much cleaner.	2016-10-15 23:19:44 +02:00
David Given	f06b51c981	Keep track of register types as well as attributes --- the type being how we ... find new registers when evicting values. Input constraints work (they were being ignored before). Various bug fixing so they actually work.	2016-10-12 22:58:46 +02:00
David Given	a3cfe6047f	More rigorous dealing of IR groups; no need for is_generated and is_root any ... more (but now passes are required to set IR roots properly when changing instructions).	2016-10-01 22:58:29 +02:00
