Re: ARM: where are special registers?

[Dmitry Smirnov <divis1969@mail.ru>]

I've found in ch.11.1 at http://sourceware.org/gdb/current/onlinedocs/gdbint_11.html#SEC89 :
<quote>
A description may come from a user specified file (XML), the remote `qXfer:features:read' packet (also XML), or from any custom to_read_description routine in the target vector. For instance, the remote target supports guessing whether a MIPS target is 32-bit or 64-bit based on the size of the `g' packet.
<quote/>

Is there any example of this XML?
What remote stub shall respond to "qXfer:features:read"? Just this XML content?
Am I right that before GDB asks for "qXfer:features:read", I shall implement "qSupported" handling in a stub with this "qXfer:features:read" as a response?
