Slava Pestov 608fb054f2 compiler.cfg: Some code cleanups, update stack-analysis and phi-insertion to work on CFGs with critical edges 2009-07-12 22:22:46 -05:00
Slava Pestov 90daf6d03d compiler.cfg: change representation of ##phi nodes. The input slot of ##phi nodes is now an assoc mapping predecessors to values, rather than a sequence of values. This ensures that optimization which delete predecessors can be implemented 2009-07-02 17:10:50 -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
