For the paper we can talk about the find dmd-anal pass, but in showing the payoff from single-entry etc we will have to compare like with like; i.e. not claim the big wins here as wins for single-entry- ness. We'd also flirted with `-flate-dmd-anal` (complete with worker/wrapper) which could show greater benefits still (from the w/w). I hypothesise that if we did `-flate-dmd-anal` then the final dmd-anal pass would buy very little except the correct single-entry info. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11731#comment:46 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
