ghc-lib GHC.Driver.Main Write interface files
ioMsgMaybe :: IO (Messages GhcMessage, Maybe a) -> Hsc aghc-lib GHC.Driver.Main Deal with errors and warnings returned by a compilation step In order to reduce dependencies to other parts of the compiler, functions outside the "main" parts of GHC return warnings and errors as a parameter and signal success via by wrapping the result in a Maybe type. This function logs the returned warnings and propagates errors as exceptions (of type SourceError). This function assumes the following invariants:
- If the second result indicates success (is of the form 'Just x'), there must be no error messages in the first result.
- If there are no error messages, but the second result indicates failure there should be warnings in the first result. That is, if the action failed, it must have been due to the warnings (i.e., -Werror).
