#9659: Offer branchless conditional (CMOV) primop -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- I'd like to see something similar to C's `?:`, like {{{#!hs ifInt#, boolInt# :: Int# -> Int# -> Int# -> Int# }}} We could then write things like {{{#!hs ifInt# (x <# y) 12# (x +# 17#) boolInt# potato cannon (y ># 2) }}} When the value of the test is difficult to predict, this would be better than the usual branching `if` or `case`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9659 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
