#13570: CoreFVs patch makes n-body slower -------------------------------------+------------------------------------- Reporter: simonpj | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #13629 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by kavon): I'm surprised `n-body` doesn't improve after that patch. Could you attach the assembly file? I'm wondering if the stack save/restores are still being emitted around the `sqrtsd` instruction. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13570#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
