#8158: Replace IO manager's IntMap with a mutable hash table -------------------------------+------------------------------------------- Reporter: bos | Owner: Type: feature | Status: patch request | Milestone: 7.8.1 Priority: normal | Version: 7.7 Component: | Keywords: libraries/base | Architecture: Unknown/Multiple Resolution: | Difficulty: Easy (less than 1 hour) Operating System: | Blocked By: Unknown/Multiple | Related Tickets: Type of failure: Other | Test Case: | Blocking: | -------------------------------+------------------------------------------- Comment (by simonmar): @bos: GHC has a `FastMutInt` type for this purpose, which is a 1-element mutable unboxed array. I'd be interested to know whether performance differs between this and `ForeignPtr`. source:ghc/compiler/utils/FastMutInt.lhs -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8158#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
