* target-arm: Add AArch64 gdbstub supportAlexander Graf2013-09-101-0/+46
| | | | | | | | | | | | | | | We want to be able to debug AArch64 guests. So let's add the respective gdb stub functions and xml descriptions that allow us to do so.

* gdb-xml: fix hacks in powerpc register numberingNathan Froyd2009-07-124-20/+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.

* Work around QEMU GDB stub suboptimalityaurel322009-03-072-0/+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.

* target-ppc: Add XML files for PowerPC registersaurel322009-01-245-0/+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.
