    v27 v28  
    1111In timescale terms it looks like this: 
    1212 * GHC 6.10 will have nothing new at all 
     13 
    1314 * 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  * Work on Step 3 will proceed in 2009. 
     15 
     16 * Work on Step 3 will proceed in 2009, but at a slower pace because John's internship ends in Oct 2008. 
     17 
    1518 * 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.
