An Object Oriented CHILL debugger

We present the design and implementation of a debugger for Object-Oriented CHILL that has three object models: module, region and task modes. Besides basic facilities for general debugging, the Object-Oriented CHILL debugger provides facilities for showing information of object types (modes), inheritance, visibility and dynamic bindings. To provide debugging facilities for these object-oriented properties we have newly designed or extended the GNU debugger, GDB. Since our implementation is based on the translator, the additional considerations such as investigating original line numbers for source level debugging are supported.
