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`

Register spilling to the stack frame works, more or less. 2016-10-15 20:53:56 +00:00			`uint32_t type;`
Precisely one stack hreg gets allocated for each vreg/congruence group for eviction; this prevents us from having to worry about moving values from stack slot to stack slot, which is hard. 2018-09-08 16:59:55 +00:00			`struct hreg* evicted; /* stack slot to evict to */`

Add (pretty crummy) support for register aliases and static pairs of registers. We should have enough functionality now for rather buggy 8-bit ints and doubles. Rework the table and the platform.c to match. 2016-10-21 21:31:00 +00:00			`const char* id;`

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;`
