#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): There are no NOINLINE in code we are using in production but behavior is similar - works faster with unused field with ExistentialQuantification. So it disables not only CPR but some other optimizations as well. What's the conclusion then? Is that fixable or I need to look for other examples? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10069#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
