Slava Pestov	692b479302	Split off local-optimization combinator into compiler.cfg.local, factor out CFG -> MR into compiler.cfg.mr, split off GC check insertion into a new compiler.cfg.gc-checks pass	2009-05-31 12:20:46 -05:00
Slava Pestov	e04df76f60	Various codegen improvements: - new-insn word to construct instructions - cache RPO in the CFG - re-organize low-level optimizer so that MR is built after register allocation - register allocation now stores instruction numbers in the instructions themselves - split defs-vregs into defs-vregs and temp-vregs	2009-05-29 13:11:34 -05:00
