Slava Pestov e2044602aa compiler.cfg.linear-scan: debugging spilling, add more assertions 2009-07-07 13:01:27 -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
