data Hooks #

emptyHooks :: Hooks #

Hooks can be used by GHC API clients to replace parts of the compiler pipeline. If a hook is not installed, GHC uses the default built-in behaviour

lookupHook :: (Hooks -> Maybe a) -> a -> DynFlags -> a #

getHooked :: (Functor f, HasDynFlags f) => (Hooks -> Maybe a) -> a -> f a #

dsForeignsHook :: Hooks -> Maybe ([LForeignDecl GhcTc] -> DsM (ForeignStubs, OrdList (Id, CoreExpr))) #

tcForeignImportsHook :: Hooks -> Maybe ([LForeignDecl GhcRn] -> TcM ([Id], [LForeignDecl GhcTc], Bag GlobalRdrElt)) #

tcForeignExportsHook :: Hooks -> Maybe ([LForeignDecl GhcRn] -> TcM (LHsBinds GhcTcId, [LForeignDecl GhcTcId], Bag GlobalRdrElt)) #

hscFrontendHook :: Hooks -> Maybe (ModSummary -> Hsc FrontendResult) #
