Slava Pestov 2e07fcdd6d compiler.cfg: Fix unit tests 2009-07-21 22:25:19 -05:00
Daniel Ehrenberg 9ae962ded6 Phi elimination doesn't have the swap problem now 2009-07-16 22:42:13 -05:00
Slava Pestov a17293a828 compiler.cfg: update unit tests for compiler.cfg.comparisons 2009-07-14 12:06:55 -05:00
Slava Pestov 07d8bed106 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 2a63722c91 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 968a9bb666 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
