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)

hscCompileCoreExprHook :: Hooks -> Maybe (HscEnv -> SrcSpan -> CoreExpr -> IO ForeignHValue)

ghcPrimIfaceHook :: Hooks -> Maybe ModIface

runPhaseHook :: Hooks -> Maybe (PhasePlus -> FilePath -> DynFlags -> CompPipeline (PhasePlus, FilePath))

runMetaHook :: Hooks -> Maybe (MetaHook TcM)

linkHook :: Hooks -> Maybe (GhcLink -> DynFlags -> Bool -> HomePackageTable -> IO SuccessFlag)

runRnSpliceHook :: Hooks -> Maybe (HsSplice GhcRn -> RnM (HsSplice GhcRn))

getValueSafelyHook :: Hooks -> Maybe (HscEnv -> Name -> Type -> IO (Maybe HValue))

createIservProcessHook :: Hooks -> Maybe (CreateProcess -> IO ProcessHandle)
