#6135: Unboxed Booleans ---------------------------------+------------------------------------------ Reporter: benl | Owner: jstolarek Type: feature request | Status: new Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.4.1 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: #605 | ---------------------------------+------------------------------------------ Comment(by tibbe): One possible use of unboxed booleans is branchless search. There are some algorithms where you can replace branches (e.g. case statements) with bit twiddling operators. I believe Gregory Collins used one such trick in the hashtables package. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/6135#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
