Thanks for confirming that.

> But an additional thing: if user sets "-XX:-UseUnalignedAccesses" I think that should be enought to stop all of them all. Also I'm doubt ful of the usefulness of Avoid flag. I don't see any case where I would have Avoid = false but also UseUnAl= false. Right now I always use Avoid = !UseUnal.

And I use it the same way as you do. `AvoidUnalignedAccesses` is derived from the aarch64 counterpart. I guess maybe it's time to let it go.
