Hi,
This is the current iteration of gdbstub refactoring and SVE support.
I've fixed a few of the bugs caught up in review and dropped the
pseudo VG register. You can still read the state of zcr_el1 via the
existing sysreg support (which doesn't allow writing). I've also
included a couple of Damian's fixes to the gdbstub which I'll include
in the final PR.
The following patches need review
08 - gdbstub extend GByteArray to read register helper
09 - target arm prepare for multiple dynamic XMLs
12 - target arm generate xml description of our SVE re
13 - tests tcg add a configure compiler check for ARMv
15 - tests tcg aarch64 userspace system register test
16 - tests guest debug add a simple test runner
17 - tests tcg aarch64 add a gdbstub testcase for SVE
18 - tests tcg aarch64 add SVE iotcl test
19 - tests tcg aarch64 add test sve ioctl guest debug
