1. mkOpFormRn :: LHsCmdTop GhcRn -> LHsExpr GhcRn -> Fixity -> LHsCmdTop GhcRn -> RnM (HsCmd GhcRn)

2. data LookingFor

   ghc	GHC.Rename.Unbound

   No documentation available.

3. addNoNestedForallsContextsErr :: HsDocContext -> NestedForallsContextsIn -> LHsType GhcRn -> RnM ()

   ghc	GHC.Rename.Utils

   A common way to invoke noNestedForallsContextsErr.

4. noNestedForallsContextsErr :: NestedForallsContextsIn -> LHsType GhcRn -> Maybe (SrcSpan, TcRnMessage)

   ghc	GHC.Rename.Utils

   Examines a non-outermost type for foralls or contexts, which are assumed to be nested. For example, in the following declaration:

   instance forall a. forall b. C (Either a b)
   

   The outermost forall a is fine, but the nested forall b is not. We invoke noNestedForallsContextsErr on the type forall b. C (Either a b) to catch the nested forall and create a suitable error message. noNestedForallsContextsErr returns Just err_msg if such a forall or context is found, and returns Nothing otherwise. This is currently used in the following places:
   • In GADT constructor types (in rnConDecl). See Note [GADT abstract syntax] (Wrinkle: No nested foralls or contexts) in GHC.Hs.Type.
   • In instance declaration types (in rnClsIntDecl and rnSrcDerivDecl in GHC.Rename.Module and renameSig in GHC.Rename.Bind). See Note [No nested foralls or contexts in instance types] in GHC.Hs.Type.

5. getInstancesForType :: GhcMonad m => Type -> m [ClsInst]

   ghc	GHC.Runtime.Eval

   No documentation available.

6. lookupRdrNameInModuleForPlugins :: HasDebugCallStack => HscEnv -> ModuleName -> RdrName -> IO (Maybe (Name, ModIface))

   ghc	GHC.Runtime.Loader

   Finds the Name corresponding to the given RdrName in the context of the ModuleName. Returns Nothing if no such Name could be found. Any other condition results in an exception:

   • If the module could not be found
   • If we could not determine the imports of the module
   Can only be used for looking up names while loading plugins (and is *not* suitable for use within plugins). The interface file is loaded very partially: just enough that it can be used, without its rules and instances affecting (and being linked from!) the module being compiled. This was introduced by 57d6798. Need the module as well to record information in the interface file

7. data Platform

   ghc	GHC.Settings

   Platform description This is used to describe platforms so that we can generate code for them.

8. Platform :: ArchOS -> PlatformWordSize -> ByteOrder -> Bool -> Bool -> Bool -> Bool -> Bool -> Bool -> Bool -> Bool -> !Maybe PlatformConstants -> Platform

   ghc	GHC.Settings

   No documentation available.

9. data PlatformMisc

   ghc	GHC.Settings

   Platform-specific settings formerly hard-coded in Config.hs. These should probably be all be triaged whether they can be computed from other settings or belong in another another place (like Platform above).

10. PlatformMisc :: String -> Bool -> Bool -> String -> PlatformMisc

    ghc	GHC.Settings

    No documentation available.
