Oh, good question -- what the TCG backend emits as vector
operations or not will depend on the host CPU (eg whether
it supports AVX1/AVX2/etc).
If the test case can be cut down to a Linux userspace
program that can be run under the qemu-arm single-binary
emulator that will probably also be easier to debug than
"boot whole guest kernel and wait for it to get to a selftest".
thanks
