gdbstub: Fix i386/x86_64 machine description and add control registers
The machine description we send is being (silently) thrown on the floor by GDB and GDB silently uses the default machine description, because the xml parse fails on <feature> nested within <feature>. Changes to the xml in qemu source code have no effect. In addition, the default machine description has fs_base, which fails to be retrieved, which breaks the whole register window. Add it and the other control registers. Signed-off-by: Doug Gale <doug16k@gmail.com> Message-Id: <20190124040457.2546-1-doug16k@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
