findRetainersOf :: Maybe Int -> [ClosurePtr] -> [ClosurePtr] -> DebugM [[ClosurePtr]] Source #
findRetainersOfConstructor :: Maybe Int -> [ClosurePtr] -> String -> DebugM [[ClosurePtr]] Source #

findRetainers :: Maybe Int -> [ClosurePtr] -> (ClosurePtr -> SizedClosure -> DebugM Bool) -> DebugM [[ClosurePtr]] Source #
From the given roots, find any path to one of the given pointers. Note: This function can be quite slow! The first argument is a limit to how many paths to find. You should normally set this to a small number such as 10.
