1. Is it possible to modify gdb to support architectures with multiple
memory spaces in a "user friendly" way (where "user friendly" is
something like what David Taylor described in
http://sources.redhat.com/ml/gdb/2001-02/msg00090.html)? So far my
impression is yes.
Yes --- with the understanding that it's restricted to just distinct
code and data spaces at the moment --- you can say:
x/i (@code char *) 0x1234
x/i (@data char *) 0x1234
and it'll do the right thing, if you define the ADDRESS_TO_POINTER and
POINTER_TO_ADDRESS methods appropriately.
(Hey, this isn't in the GDB manual anywhere!)
But you've actually got a case where this needs to be extended to
support an arbitrary set of architecture-defined spaces, which the
current code does not support. If I recall correctly, this was
discussed when the current @code and @data support went in, but it was
left as a future extension, since we didn't know of any architectures
that actually wanted it. Now we do.
