The monad
The monad used by Core-to-Core passes to access common state, register simplification statistics and so on
runCoreM :: HscEnv -> RuleBase -> UniqSupply -> Module -> ModuleSet -> PrintUnqualified -> SrcSpan -> CoreM a -> IO (a, SimplCount) Source #
Reading from the monad
getDynFlags :: HasDynFlags m => m DynFlags Source #
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 #
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
fatalErrorMsg :: SDoc -> CoreM () Source #
Output a fatal error to the screen. Note this does not by itself cause the compiler to die
fatalErrorMsgS :: String -> CoreM () Source #
Output a fatal string error to the screen. Note this does not by itself 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
dumpIfSet_dyn :: DumpFlag -> String -> SDoc -> CoreM () Source #
Show some labelled SDoc if a particular flag is set or at a verbosity level of -v -ddump-most or higher
Getting Names
thNameToGhcName :: Name -> CoreM (Maybe Name) Source #
Attempt to convert a Template Haskell name to one that GHC can
understand. Original TH names such as those you get when you use
the 'foo syntax will be translated to their equivalent GHC name
exactly. Qualified or unqualifed TH names will be dynamically bound
to names in the module being compiled, if possible. Exact TH names
will be bound to the name they represent, exactly.
