Hello haskell-cafe,
Page http://community.livejournal.com/ru_lambda/44716.html contains three very simple but long-working benchmark functions:
dummy :: [Int] -> [Int] dummy [] = [] dummy (x:xs) = x:dummy (dummy xs)
dummy2 :: [Int] -> [Int] dummy2 = dum [] where dum w [] = w dum w (x:xs) = dum (w++[x]) (dummy2 xs)
dummy3 :: [Int] -> [Int] dummy3 = dum [] where dum w [] = reverse w dum w (x:xs) = dum (x:w) (dummy3 xs)
*Main> dummy [1..21] [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21] (16.97 secs, 157120860 bytes) *Main> dummy2 [1..21] [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21] (2.42 secs, 151470452 bytes) *Main> dummy3 [1..21] [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21] (1.78 secs, 84642856 bytes) *Main>
Is it interesting for testing haskell compilers?
Nice, I've added this to 'nobench': http://www.cse.unsw.edu.au/~dons/code/nobench/imaginary/ru_list You can see what the different compilers do to it here: http://www.cse.unsw.edu.au/~dons/nobench/i686/results.html -- Don
