Yes.  I've submitted another patch that does this.

Yes.  I've committed a change that does this.

The D10V no longer has any convertible registers, so those functions
certainly should never be called.  I just assumed I'd get a gdbarch
error if I didn't provide some value for them.  Are you saying I can
just delete the set_gdbarch_* calls altogether, and the dummy
functions they register?  (I guess since the corresponding macros are
optional, that would make sense...)

Thanks for looking it over!
