Change 66056 by peter at peter_daintree on 2004/11/29 20:58:09

	finish off gdb_machdep.c based on my understanding to date.
	We can only get the scratch registers from the trapframe since
	we do not save them in the pcb at context switch.
	Note to self: the register numbers are defined in gdb/amd64-tdep.c
