12	12	* GHC 6.10 will have nothing new at all
13		* Immediately after the code fork for 6.10 we'll commit the new stuff for Step 1 and Step 2. By the end of 2008 (latest) we hope to be using the Step 2 pipeline in anger, and can discard the existing code generator entirely.

By the end of 2008 (latest) we hope to be using the Step 2 pipeline in anger, and can discard the existing code generator entirely. To be fair, at this point you probably won't see any performance improvements; indeed compilation could be a bit slower. But the pipeline will be far more modular and flexible.
14	14	* Work on Step 3 will proceed in 2009.

16		Once Step 2 is done, others can help! For example, Cmm-to-Cmm optimisations will be easy.
	15	* At the same time, others can help! In particular, Cmm-to-Cmm optimisations will be easy. And some of them really should yield performance improvements.
