#9646: Simplifer non-determinism leading to 8 fold difference in run time performance -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: closed Priority: normal | Milestone: 7.10.1 Component: Compiler | Version: 7.8.3 Resolution: fixed | Keywords: Operating System: Linux | Architecture: x86_64 (amd64) Type of failure: Runtime | Difficulty: Unknown performance bug | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by jstolarek): It would be great if we could have a test for this so we're sure this does not regress again. I looked at the repo and the code to reproduce this is pretty big. I wonder if it could be reduced further to include it in the testsuite. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9646#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
