Cortex-M CPUs with MVE should advertise this fact to gdb, using the org.gnu.gdb.arm.m-profile-mve XML feature, which defines the VPR register. Presence of this feature also tells gdb to create pseudo-registers Q0..Q7, so we do not need to tell gdb about them separately. Note that unless you have a very recent GDB that includes this fix: http://patches-tcwg.linaro.org/patch/58133/ gdb will mis-print the individual fields of the VPR register as zero (but showing the whole thing as hex, eg with "print /x $vpr" will give the correct value).
