- *Note that the new code generator appears about 10x slower than the old. Slowdown attributed to Hoopl dataflow.* See [ Google Plus post by Simon Marlow](https://plus.google.com/107890464054636586545/posts/dBbewpRfw6R).

- Fixed-point algorithm rewritten to reduce duplicate computation. (Simon Marlow in late 2011. Also Edward Yang \[circa Summer 2011?\]. There is still some work to be done here (easily seen if you try tracing some of the simple examples in the Hoopl repository) but a more clever iterative sweeping algorithm languishing in my repository suffers from a subtle bug that surfaces when tested on GHC. -- ezyang

- Fixed-point algorithm rewritten to reduce duplicate computation. (Simon Marlow in late 2011. Also Edward Yang in spring 2011.) Is there any more? I suggest looking at traces in the simple cases.

- Change in representation of blocks, Simon Marlow, late 2011. (Details?) Performance difference almost too small to be measurable, but Simon M likes the new rep anyway.
