Jones - Secrets of the GHC Inliner
|
|
|
|
Inlining:
|
|
-- | Function composition.
|
|
{-# INLINE (.) #-}
|
|
-- Make sure it has TWO args only on the left, so that it inlines
|
|
-- when applied to two functions, even if there is no final argument
|
|
(.) :: (b -> c) -> (a -> b) -> a -> c
|
|
(.) f g = \x -> f (g x)
|
|
|
|
-- The following will not be inlined for 2 args available, since it has 3:
|
|
(.) f g x = f (g x)
|
|
|
|
INLINABLE pragma - for recommendation to inline, not a force
|
|
|
|
-funfolding-use-threshold=16
|
|
|
|
Note: not-exported functions are inlined by default within a module
|
|
|
|
-ddump-hi - to dump the hi-file (inlined functions should not be there).
