#9159: cmm case, binary search instead of jump table --------------------------------------------+------------------------------ Reporter: wojteknar | Owner: Type: feature request | Status: new Priority: lowest | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime performance bug | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: --------------------------------------------+------------------------------ Changes (by wojteknar): * priority: low => lowest Comment: Okay, this really is a corner case of case statement. For one range the heuristics could be "fill factor". For multiple ranges it gets really difficult. The workaround with Enum and tagToEnum# works fine. Perhaps I should just close this ticket? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9159#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
