Refactor mcg.h as it's getting a bit big; keep track of register variables. 2016-10-01 22:30:33 +00:00			`#ifndef PROCEDURE_H`

			`struct local`
			`{`
Add zrl opcode. Keep track of local sizes as well as offsets. 2016-10-02 14:08:46 +00:00			`int size;`
			`int offset;`

Function termination gets routed through an exit block; we now have prologues and epilogues. mcgg now exports some useful data as headers. Start factoring out some of the architecture-specific bits into an architecture-specific file. 2016-10-15 16:38:46 +00:00			`struct basicblock* entry;`

Register spilling to the stack frame works, more or less. 2016-10-15 20:53:56 +00:00			`int locals_size;`

References to the stack frame are now rendered properly. 2016-10-15 21:33:30 +00:00			`int fp_to_ab;`

Stop passing proc around, and use a global instead --- much cleaner. 2016-10-15 21:19:44 +00:00			`extern struct procedure* current_proc;`
