Could that be the case here? From:

{
...
if (! tdesc_has_registers (tdesc))
tdesc = tdesc_i386_linux;

order may be required for back compatibility. A deeper audit
with that in mind is in order.
Thanks,

Do you mean that this might impact backward compatibility with older gdbservers (or other remotes) that don't send XML target descriptions and just assume a certain "well-known" register numbering?
