findRetainersOf :: Maybe Int -> [ClosurePtr] -> [ClosurePtr] -> DebugM [[ClosurePtr]]

findRetainersOfConstructor :: Maybe Int -> [ClosurePtr] -> String -> DebugM [[ClosurePtr]]

findRetainersOfConstructorExact :: Maybe Int -> [ClosurePtr] -> String -> DebugM [[ClosurePtr]]

findRetainers :: Maybe Int -> [ClosurePtr] -> (ClosurePtr -> SizedClosure -> DebugM Bool) -> DebugM [[ClosurePtr]]

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.

addLocationToStack :: [ClosurePtr] -> DebugM [(SizedClosureC, Maybe SourceInformation)]
