#11668: SPEC has a runtime cost if constructor specialization isn't performed -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 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 bgamari): It seems that SPEC is correctly eliminated if `-fspec-constr` is used so this should only be a problem for code expecting constructor specialization that gets compiled with `-O1`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11668#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
