    v28 v29  
    1212 * GHC 6.10 will have nothing new at all 
    1313 
    14  * 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.  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 * Immediately after the code fork for 6.10 we'll commit the new stuff for Step 1 and Step 2 to the HEAD.

     16 * By the end of 2008 (and probably much earlier) 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.

    1618 * Work on Step 3 will proceed in 2009, but at a slower pace because John's internship ends in Oct 2008.
