Better management of register data. Add struct hreg. 2016-10-05 19:00:28 +00:00			`#ifndef REG_H`

Calculate phi congruency groups; use them to solve the importing-hreg-from-the-future problem (probably poorly). 2016-10-09 20:04:20 +00:00			`struct phicongruence`

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 20:58:46 +00:00			`uint32_t type;`

Overhaul of everything phi related; critical edge splitting now happens before anything SSA happens; liveness calculations now look like they might be working. 2016-10-07 22:21:23 +00:00			`struct hop* defined;`

Basic register allocation works! 2016-10-08 21:32:54 +00:00			`typedef PMAPOF(struct hreg, struct vreg) register_assignment_t;`
