To my understanding, the values of "expedite" registers are always transferred
from the "server" to GDB client. With every step you take, or any stop you do,
GDB client will know about the value of "expedite" registers. In case of ARC,
those are the "program counter" and "stack pointer" registers.
I _think_ the "dat" files are the mechanism holding information about that.
After all it is generated from the XML and we also followed other targets
in doing so.
