@Joachim: is this patchset still in limbo? If there's no measurable
#9136: Constant folding in Core could be better -------------------------------------+------------------------------------- Reporter: simonpj | Owner: nomeata Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: Runtime | Blocked By: performance bug | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by nomeata): performance impact, but it improves code and doesn't hurt performance, I don't see why you cannot merge it. Compiler code complexity would be one reason to not merge it. Other than that I mostly forgot about this... and so I’m not sure about the completeness of my work (and it needs more comments, as always). I’ll eventually return to it, but without high priority. Just leave it assigned to me. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9136#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
