#16040: Unboxing-Related Performance Issue with Polymorphic Functions -------------------------------------+------------------------------------- Reporter: _recursion | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by _recursion): A cursory read looks like it would, yes! Nevertheless, this is pretty concerning. I now have no idea why most of our codebase isn't getting hit by this issue, and suddenly I've run into a place where it occurs. I'm a little afraid for the performance stability of our code across GHC upgrades now. Is it something that could only be fixed by nested CPR or could a band-aid fix be put in place, do you think? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16040#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
