#10069: CPR related performance issue -------------------------------------+------------------------------------- Reporter: pacak | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1-rc2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by pacak): Those NOINLINE pragmas are required to replicate the behavior I'm getting in the production code. Generated core looks the same, generated assembly code is different though. With more fields added (see attachment) performance difference is 4x, goes away as soon as I get rid of forall'ed field. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10069#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
