Bansidhar, DDD simply runs on top of the command line debugger. While it may not always graphically support every feature that each command line debugger supports, you have full access to the command line debugger from the DDD console window - just as though you were running the command line debugger at the terminal. From there, you should have access to all the features of the underlying command line debugger. If features don't seem to be available to you from there, then I would suspect that the problem is not with DDD, but with your debugger. If you can run the debugger alone and do have access to these features, then it would be a subject that would be better taken up with the maintainers of DDD, rather than on the GCC list.

I want to know are there any architectural dependencies which could restrict some of the functionalities of ddd. According to my knowledge ddd is target independent and the only thing it does is it places a bridge between the user and the debugger. But if ddd is being used with debugger for target 'x' then it does not enable few features e.g. memory and registers. What can be the problem . Please help me .. Thanks in advance, --Bansidhar
