target/i386: Add GDB XML description for SSE registers Add an XML description for SSE registers (XMM+MXCSR) for both X86 and X86-64 architectures in the GDB stub: - configure: Define gdb_xml_files for the X86 targets (32 and 64bit). - gdb-xml/i386-32bit-sse.xml & gdb-xml/i386-64bit-sse.xml: The XML files that contain a description of the XMM + MXCSR registers. - gdb-xml/i386-32bit.xml & gdb-xml/i386-64bit.xml: wrappers that include the XML file of the core registers and the other XML file of the SSE registers. - target/i386/cpu.c: Modify the gdb_core_xml_file to the new XML wrapper, modify the gdb_num_core_regs to fit the registers number defined in each XML file.

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>
