    • cleanup

    • supportsLanguageFrontend

      public boolean supportsLanguageFrontend​(LanguageFrontend lang)
      Specifies, whether this pass supports this particular language frontend. This defaults to true and needs to be overridden if a different behaviour is wanted.

      Note: this is not yet used, since we do not have an easy way at the moment to find out which language frontend a result used.

      Parameters:
      lang - the language frontend
      Returns:
      true by default
