#9136: Constant folding in Core could be better --------------------------------------------+------------------------------ Reporter: simonpj | Owner: nomeata Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime performance bug | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: --------------------------------------------+------------------------------ Changes (by nomeata): * status: new => patch Comment: Nofib shows that this optimization yields no measurable gain – most likely because later stages (maybe gcc) perform them anyways. So do we still want it, for the sake of pleasing Core, and maybe for the benefit of other backends like GHCJS? If yes, this can go in, so marking this as ready for review. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9136#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
