The monad
The monad used by Core-to-Core passes to access common state, register simplification statistics and so on
Instances
| Monad CoreM # | |
| Functor CoreM # | |
| Applicative CoreM # | |
| MonadIO CoreM # | |
| Alternative CoreM # | |
| MonadPlus CoreM # | |
| MonadUnique CoreM # | |
Defined in CoreMonad Methods getUniqueSupplyM :: CoreM UniqSupply Source # getUniqueM :: CoreM Unique Source # getUniquesM :: CoreM [Unique] Source # | |

runCoreM :: HscEnv -> RuleBase -> UniqSupply -> Module -> ModuleSet -> PrintUnqualified -> SrcSpan -> CoreM a -> IO (a, SimplCount) Source #
Reading from the monad
getDynFlags :: HasDynFlags m => m DynFlags Source #
getOrigNameCache :: CoreM OrigNameCache Source #
The original name cache is the current mapping from Module and
OccName to a compiler-wide unique Name
Writing to the monad
addSimplCount :: SimplCount -> CoreM () Source #
Lifting into the monad
liftIOWithCount :: IO (SimplCount, a) -> CoreM a Source #
Lift an IO operation into CoreM while consuming its SimplCount
liftIO1 :: MonadIO m => (a -> IO b) -> a -> m b Source #
Lift an IO operation with 1 argument into another monad
liftIO2 :: MonadIO m => (a -> b -> IO c) -> a -> b -> m c Source #
Lift an IO operation with 2 arguments into another monad
liftIO3 :: MonadIO m => (a -> b -> c -> IO d) -> a -> b -> c -> m d Source #
Lift an IO operation with 3 arguments into another monad
liftIO4 :: MonadIO m => (a -> b -> c -> d -> IO e) -> a -> b -> c -> d -> m e Source #
Lift an IO operation with 4 arguments into another monad
Global initialization
reinitializeGlobals :: CoreM () Source #
Deprecated: It is not necessary to call reinitializeGlobals. Since GHC 8.2, this function is a no-op and will be removed in GHC 8.4
Dealing with annotations
getAnnotations :: Typeable a => ([Word8] -> a) -> ModGuts -> CoreM (UniqFM [a]) Source #
Get all annotations of a given type. This happens lazily, that is no deserialization will take place until the [a] is actually demanded and the [a] can also be empty (the UniqFM is not filtered).
This should be done once at the start of a Core-to-Core pass that uses annotations.
See Note [Annotations]
getFirstAnnotations :: Typeable a => ([Word8] -> a) -> ModGuts -> CoreM (UniqFM a) Source #
Get at most one annotation of a given type per Unique.
Screen output
errorMsg :: SDoc -> CoreM () Source #
Output an error to the screen. Does not cause the compiler to die.
errorMsgS :: String -> CoreM () Source #
Output an error to the screen. Does not cause the compiler to die.
fatalErrorMsg :: SDoc -> CoreM () Source #
Output a fatal error to the screen. Does not cause the compiler to die.
fatalErrorMsgS :: String -> CoreM () Source #
Output a fatal error to the screen. Does not cause the compiler to die.
debugTraceMsg :: SDoc -> CoreM () Source #
Outputs a debugging message at verbosity level of -v or higher
debugTraceMsgS :: String -> CoreM () Source #
Output a string debugging message at verbosity level of -v or higher
