Anyways, with #10677 resp. D1137, the conditions should be `condition != 0`, which will hopefully be turned into `condition`.
Yes, I believe that case is handled already. Here is an example (build with `-O`): {{{ f :: Double -> Double f x = if x > 0 then 1 else 2 }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10750#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
