Re: [PATCH] Teach -data-list-register-values to not include unavailable registers

Why a new argument rather than just having MI annotate unavailable

   -data-list-register-values x 0 8

The MI front-end doesn't parse the output like this, as each register is represented by "number-value" pair. 


Is it not useful to see the unavailable ones?
Processor may have a large number of registers, and users are only interested in collected or available registers in a traceframe. In this case, it is not useful to show (a large of number of) unavailable registers.
