I think Alexiev is off to see Santa 'til January .. but
this is a not from a patch he dropped to the CDT mailing list
it should give you a rough idea of his way of thinking.
The part about a default "Main" group is probably CDT specific
and there for backward compatibility.
/**
* Custom command for requesting the register groups.
* It is not yet in the GDB stream.
*
* -data-list-register-groups
*
* The format of the command is:
* IN:(gdb)-data-list-register-groups
* OUT:^done,register-groups= [{name="r0", group="GRP1"},{name="r8",group="GRP2"}]
*
* It is similar of the command: "-data-list-register-values".
*
* The register group names are case sensitive.
* * The register groups appear in the Register View in order they are returns from
* the command "-data-list-register-groups".
*
* The registers appear in the groups in the order they are returned from the
* command "-data-list-register-names".
* The register names are case sensitive.
*
* If the debugger doesn<92>t support the command "-data-list-register-groups" all
* registers are added to the "Main" group.
* If there is a register returned by the command "-data-list-register-names" but not
* in the command "-data-list-register-groups" it is added to the "Main" group.
* The main group itself is added first to the Register view.
* If there is a register returned by the command "-data-list-register-groups" but not in
* the command "-data-list-register-names" the register is ignored.
