[PATCH v6 00/22] gdbstub refactor and SVE support

[Alex Bennée]

Hi,

The main change for the last iteration is the re-introduction of the
VG pseudo register. I've also applied review tags from the last post.
All that really needs looking over is the tests.

Please note that if your local GDB doesn't work the test will skip if
it fails to connect. I have to build --with-gdb pointing at a
relatively recent multiarch build.

This series is available from:

  github.com:stsquad/qemu.git gdbstub/sve-registers-v6

and is currently based of the in-flight testing PR.

The following patches need review
  08 - target i386 use gdb_get_reg helpers
  10 - target arm prepare for multiple dynamic XMLs (1 ack)
  13 - target arm generate xml description of our SVE re (1 ack)
  18 - tests tcg aarch64 add a gdbstub testcase for SVE 
  19 - tests tcg aarch64 add SVE iotcl test
  20 - tests tcg aarch64 add test sve ioctl guest debug
