  1. ParMakeNumProcessors :: ParMakeCount

    ghc GHC.Driver.Session

    Use parallelism with as many processors as possible (-j flag without an argument).

  2. DsEmptyEnumeration :: DsMessage

    ghc GHC.HsToCore.Errors.Types

    DsEmptyEnumeration is a warning (controlled by the -Wempty-enumerations flag) that is emitted if an enumeration is empty. Example(s): main :: IO () main = do let enum = [5 .. 3] print enum Here enum would yield an empty list, because 5 is greater than 3.

  3. warnAboutEmptyEnumerations :: FamInstEnvs -> DynFlags -> LHsExpr GhcTc -> Maybe (LHsExpr GhcTc) -> LHsExpr GhcTc -> DsM ()

    ghc GHC.HsToCore.Match.Literal

    Warns about [2,3 .. 1] or [b .. a] which return the empty list. For numeric literals, only works for integral types, not floating point.

  4. IfaceNumTyLit :: Integer -> IfaceTyLit

    ghc GHC.Iface.Type

    No documentation available.

  5. fromEnum :: Enum a => a -> Int

    ghc GHC.Prelude.Basic

    No documentation available.

  6. toEnum :: Enum a => Int -> a

    ghc GHC.Prelude.Basic

    No documentation available.

  7. execLineNumber :: ExecOptions -> Int

    ghc GHC.Runtime.Eval

    line number (for errors)

  8. execLineNumber :: ExecOptions -> Int

    ghc GHC.Runtime.Eval.Types

    line number (for errors)

  9. gen_Enum_binds :: SrcSpan -> DerivInstTys -> TcM (LHsBinds GhcPs, Bag AuxBindSpec)

    ghc GHC.Tc.Deriv.Generate

    No documentation available.

  10. DerivErrEnumOrProduct :: DeriveInstanceErrReason -> DeriveInstanceErrReason -> DeriveInstanceErrReason

    ghc GHC.Tc.Errors.Types

    We couldn't derive an instance either because the type was not an enum type or because it did have more than one constructor.
