Re: [cdt-dev] Parity features that don't work well (was: Signals view in CDT debugger)


>From my perspective the goal of the parity effort should be to insure that
people accustomed to using a CDI debugger don't find themselves missing
features when using a DSF debugger. If something isn't working well in CDI
then I doubt anyone will miss is very much.

It's interesting to track the other details but I think they should remain a
low priority for now. If they aren't working then they can't play much of a
part in workflow.

Although there are a few remaining things, overall I think the parity effort
is looking pretty good,
