-  <!-- HACK: The way the QEMU GDB stub code is currently written requires
-       the "integer" registers from the XML file to span the entirety of
-       NUM_CORE_REGS that non-XML-aware GDB requires.  Otherwise, XML-aware
-       GDB thinks that "coprocessor" registers from XML, such as the
-       floating-point registers, have register numbers less than
-       NUM_CORE_REGS.  This can lead to problems.  Work around it by using
-       an unnamed register as padding; NUM_CORE_REGS on Power is 71 and
-       this register is 70.  It would be fpscr for non-XML-aware GDB.  -->
