The monad
The monad used by Core-to-Core passes to register simplification statistics. Also used to have common state (in the form of UniqueSupply) for generating Uniques.

Dealing with annotations
getAnnotations :: Typeable a => ([Word8] -> a) -> ModGuts -> CoreM (ModuleEnv [a], NameEnv [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 (ModuleEnv a, NameEnv a) Source #
Get at most one annotation of a given type per annotatable item.
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
dumpIfSet_dyn :: DumpFlag -> String -> DumpFormat -> SDoc -> CoreM () Source #
Show some labelled SDoc
if a particular flag is set or at a verbosity level of -v -ddump-most
or higher
