-* This is the Firm interface to debugging support.
-*
-* @author Goetz Lindenmaier
-*
-* Firm requires a debugging module fulfilling this interface, else no
-* debugging information is passed to the backend.
-* The interface requires a datatype representing the debugging
-* information. Firm supports administrating a reference to the debug
-* information in every firm node. Further Firm optimizations call
-* routines to propagate debug information from old nodes to new nodes
-* if the optimization replaces the old ones by the new ones.
