Thanks for testing!

The documentation wasn't clear whether ECX would be updated without
the REP prefix so I included it to be on the safe side. Unfortunately
my only VIA machine is on another continent at the moment so I can't
test it myself. Can you verify that ECX isn't changed without the
REP prefix?

According to my documentation EDX isn't be modified (nor would it
make sense as it would break REP XSTORE). Are you seeing anything
different?
Thanks,
