  1. splitLookup :: Key -> Word64Map a -> (Word64Map a, Maybe a, Word64Map a)

    ghc GHC.Data.Word64Map.Strict.Internal

    Performs a split but also returns whether the pivot key was found in the original map. 

    splitLookup 2 (fromList [(5,"a"), (3,"b")]) == (empty, Nothing, fromList [(3,"b"), (5,"a")])
splitLookup 3 (fromList [(5,"a"), (3,"b")]) == (empty, Just "b", singleton 5 "a")
splitLookup 4 (fromList [(5,"a"), (3,"b")]) == (singleton 3 "b", Nothing, singleton 5 "a")
splitLookup 5 (fromList [(5,"a"), (3,"b")]) == (singleton 3 "b", Just "a", empty)
splitLookup 6 (fromList [(5,"a"), (3,"b")]) == (fromList [(3,"b"), (5,"a")], Nothing, empty)

  2. updateLookupWithKey :: (Key -> a -> Maybe a) -> Key -> Word64Map a -> (Maybe a, Word64Map a)

    ghc GHC.Data.Word64Map.Strict.Internal

    Lookup and update. The function returns original value, if it is updated. This is different behavior than updateLookupWithKey. Returns the original key value if the map entry is deleted. 

    let f k x = if x == "a" then Just ((show k) ++ ":new a") else Nothing
updateLookupWithKey f 5 (fromList [(5,"a"), (3,"b")]) == (Just "a", fromList [(3, "b"), (5, "5:new a")])
updateLookupWithKey f 7 (fromList [(5,"a"), (3,"b")]) == (Nothing,  fromList [(3, "b"), (5, "a")])
updateLookupWithKey f 3 (fromList [(5,"a"), (3,"b")]) == (Just "b", singleton 5 "a")

  3. finder_lookupHomeInterfaces :: FinderOpts -> Bool

    ghc GHC.Driver.Config.Finder

    When looking up a home module:

    • True: search interface files (e.g. in '-c' mode)
    • False: search source files (e.g. in '--make' mode)
