[PATCH 0/5] target/arm: Support MVE in gdbstub

[Peter Maydell]

This patchset's aim is to report MVE to gdb via the gdbstub.
That is done by the final patch, which is an RFC because the
gdb patches to support it are not yet upstream and so the XML
format isn't final. (Sending the XML works fine with a GDB
without the MVE support; you just don't get the auto-generated
pseudo-registers that display the Q-regs, so all you see is the
S and D reg versions of the data.)

Patches 1 through 4 are cleanup of the arm gdbstub related code of
various kinds; this part of the series should be OK to go into QEMU
as soon as it's reviewed.

Luis: you'll find that with this entire patchset a GDB built with
your patches doesn't crash, because in patch 4 I stopped QEMU
reporting FPSID and FPEXC in the org.gnu.gdb.arm.vfp XML feature.

thanks
