Hi Jan,
I am not 100% sure but I am concerned about the above output having 'enum uenum' --
which is essentially the type of the variable. And MI already reports type separately.
I recall I've made some changed before to specifically stop GDB from including the
type of variable inside value field when the type is function. So, I suggest that
this output is not included for MI. It might be OK to output a separate
field, e.g. "enum_integer_value" -- with the integer value as printed above -- but
I don't have a feeling if frontends really need that at this point.
Thanks,
