Change subject: base: add support for GDB's XML architecture definition
......................................................................
base: add support for GDB's XML architecture definition
This is done by implementing the Xfer:features:read packet of the GDB
remote protocol.
Before this commit, gem5 used the defaults of the GDB client.
With this commit, gem5 can inform the client which registers it knows
about. This allows in particular to support new registers which an older
GDB client does not yet know about.
The XML is not implemented in this commit for any arch, and falls back
almost exactly to previous behaviour. The only change is that now gem5
replies to the Supported: request which the GDB clients sends at the
beginning of the transaction with an empty feature list containing only
the mandatory PacketSize= argument.
Since the feature list does not contain qXfer:features:read, the GDB
client knows that the gem5 server does support the XML format and uses
its default registers as before.
