Detailed Description

Debug hooks for GCC.

This structure contains hooks for the debug information output
functions, accessed through the global instance debug_hooks set in
toplev.cc according to command line options.   

WARNING: Do not add new debug hook targets - DWARF will be the only
way to speak debug to the middle-end once we are able to get rid of
the remaining targets.  If you need alternate output formats instead
generate them off the DWARF representation.
