Comment (by rwbarton):

 Replying to [comment:2 nomeata]:
 > 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
 }}}
