gdbstub and plugin read register and windows support Here are my final updates for the 8.2 cycle which I can hopefully merge if we get enough review. Aside from the usual tweaks and fixes there are two new features: TCG Plugin Register Access This is based on Akihiko's previously posted series with some changes by myself. I wasn't keen on the plugin facing API so I've re-written it to use an opaque handle and hide the gdb details from the plugin. I think this allows for potential future improvements as well as being ready for up-coming heterogeneous support. The new API allowed for making the execlog register tracking a bit more flexible and able to track multiple registers. Windows Support This fairly late breaking patch finally adds support for Windows to the TCG plugins subsystem. I'm pretty pleased with Greg's approach which improves on previous attempts by avoiding re-implementing a linker for POSIX targets. I don't have access to Windows though so I'm calling on Windows users to test the solution. The following patches still need review: contrib/plugins: extend execlog to track register changes plugins: add an API to read registers gdbstub: expose api to find registers tests/avocado: update the tcg_plugins test tests/tcg: add an explicit gdbstub register tester target/arm: hide aliased MIDR from gdbstub target/arm: hide all versions of DBGD[RS]AR from gdbstub target/arm: hide the 32bit version of PAR from gdbstub gdb-xml: fix duplicate register in arm-neon.xml
