2019-02-05gdbstub: Fix i386/x86_64 machine description and add control registersDoug Gale6-257/+387
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>

2017-06-07target/i386: Add GDB XML description for SSE registersAbdallah Bouassida4-0/+140
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.

2017-05-05target/i386: Add GDB XML register description supportAbdallah Bouassida2-0/+138
This patch implements XML target description support for X86 and X86-64 architectures in the GDB stub, as the way with ARM and PowerPC: - gdb-xml/32bit-core.xml & gdb-xml/64bit-core.xml: Adding the XML target description files, these files are picked from GDB source code. - configure: Define gdb_xml_files for X86 targets. - target/i386/cpu.c: Define gdb_core_xml_file and gdb_arch_name to add XML awareness for this architecture, modify the gdb_num_core_regs to fit the registers number defined in each XML file.

2009-07-12gdb-xml: fix hacks in powerpc register numberingNathan Froyd4-20/+2
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.

2009-03-07Work around QEMU GDB stub suboptimalityaurel322-0/+18
The current XML files claim, on floating point-supporting Power chips, that $f0 is register 70. This would be fine, except that register 70 for non-XML-aware GDB is FPSCR. More importantly, 70 is less than NUM_CORE_REGS (71) for Power, so a request for register 70 goes to the "core" register reading routines, rather than the floating-point register read routine we registered with gdb_register_coprocessor. Therefore, when we are talking to an XML-aware GDB, we claim that register has zero width, which causes the rest of QEMU's GDB stub to send an error back to GDB, which causes GDB to be unable to read the floating-point registers. (The problem is also present for SPE registers and occurs in a slightly different way for Altivec registers.) The best way to fix this is to have the "core register" XML files for PPC32 and PPC64 claim that there is a 4-byte register 70, which causes $f0 to be register 71, and everything works just fine from that point forward.

2009-01-24target-ppc: Add XML files for PowerPC registersaurel325-0/+244
These files are nearly identical to the XML files provided with GDB. The only difference is that power-{fpu,spe}.xml do not assign register numbers; the internal QEMU machinery takes care of that. Define gdb_xml_files for ppc targets in configure as well.
