Created attachment 176295 [details]
patch containing code to allow getDescription() to use different formats when being retrieved as an editor name

context: at times, multiple "CSourceNotFound" editors will be opened when viewing frames in the Debug "stack" and then leaving them open during further execution and later viewing, or even at times when disassembly-stepping such contexts.

the problem is exacerbated when the StackFrameDMC objects held by various VM objects have the instruction pointer address associated with them updated; this seems especially prevalent with recent EDC changes to prevent the instruction pointer address from getting stale so that nested variable scoping and variable change highlighting perform correctly, but can be reproduced with DSF-GDB as well.

the attached patch EditorNameForFrameWithoutFilename.patch contains changes for org.eclipse.cdt.debug.core, org.eclipse.cdt.debug.ui and org.eclipse.cdt.dsf.ui that together help create a description name for a frame VM that can be used by the editor so that the name remains the same for the editor even when the address changes.  this allows later editor comparisons to re-find such "CSourceNotFound" editors and re-use them, rather than opening new ones.
