> So running with SVE enabled, we vectorize 7 loops in find-last.cpp from the test suite. I don't see any noticeable performance impact from the vectorization, but total execution time is on the order of a couple of milliseconds, so I maybe need to increase the amount of data for a microbenchmark to see anything.

Yes that is only intended to test correctness; as I mentioned earlier, it would be good to add some MicroBenchmarks, to make this easier to measure
