-- The new register allocator in 4.08 had a bug wherein -- flow edges away from an insn which does a jump through -- a switch table were not being added to the flow graph, -- which causes computation of live ranges and thus register -- assignment to be wrong in the alternatives and default. -- This was fixed properly in the head branch (pre 4.09) -- and avoided in 4.08.1 by disabling jump table generation -- in the NCG -- it generates trees of ifs instead. module Main ( main ) where main = print (map f [1 .. 7]) {-# NOINLINE f #-} f :: Int -> Bool f 7 = False f 1 = False f 4 = False f 6 = False f 5 = False f x = if x * 10 == 20 then True else False
