Hi there

Just wondering if anybody knows anything about this. I'm using Eclipse 4.15 and CDT 9.11.

I've played around with defining some additional register groups in the Register view and they work well. However because I am using an embedded target (RISC-V) over openocd/JTAG debug launch failures are common - e.g. when I forget to switch the board on! ;-)

When I use a debug launch configuration with register groups defined and the debug launch succeeds then everything works great. But if at any stage the debug launch configuration fails then the register groups are removed from the debug launch configuration and any subsequent use of this debug launch configuration has no register groups and just displays the default "General Registers" list of all registers.

Is this the intendend behaviour here and, if so, why?
If not then does it sound like a bug and would anybody be able to point me at the relevant code that might need to be tweaked?

If you need any further information to understand my question then please don't hesitate to ask.

Thanks a lot
Regards
Tommy Murphy

In the debug launch configuration XML file register groups, if defined, are stored here:

<stringAttribute key="org.eclipse.cdt.launch.DEBUGGER_REGISTER_GROUPS" value=""/>

The code that persist this is here:

https://git.eclipse.org/c/cdt/org.eclipse.cdt.git/tree/debug/org.eclipse.cdt.debug.core/src/org/eclipse/cdt/debug/internal/core/RegisterGroupsPersistance.java#n211

However I wonder if, in the case of a failed debug launch. is groups perhaps not initialized so that the default (blank string) get stored thus losing the register group configuration details?
