tcInstDeclsDeriv :: [DerivInfo] -> [LTyClDecl GhcRn] -> [LDerivDecl GhcRn] -> TcM (TcGblEnv, [InstInfo GhcRn], HsValBinds GhcRn) Source #
Use DerivInfo for data family instances (produced by tcInstDecls1), datatype declarations (TyClDecl), and standalone deriving declarations (DerivDecl) to check and process all derived class instances.
