    gdb-xml: fix hacks in powerpc register numbering · 22555301
    Nathan Froyd authored
    The powerpc xml files contained a hack--an empty, non-existent
    register--for getting the register numbers to line up for
    newer (XML-aware) and older (non-XML-aware) GDB.  While this hack worked
    in some cases, it didn't work in all cases, notably when the user used
    `finish' or `continue': GDB would attempt to read the non-existent
    register and QEMU would complain.
    
    This patch fixes things up properly.  Instead of inserting a fake
    register, we explicitly declare the floating-point and SPE registers to
    start at 71.  This action accomplishes the same thing as the nasty hack,
    except that now GDB never tries to fetch the non-existant register 70.
