Hi Christoffer, Marc - I just threw this test your way without any explanation. The test loops, does fp arithmetic and checks the truncated result. It could be a little more dynamic have an initial run to get the sum to compare against while looping, different fp hardware may come up with a

This is a 2nd itteration for arm64, v1 patches were posted by mistake from an older branch which included several bugs. Hopefully didn't waste too much of anyones time. This patch series is a followup to the armv7 fp/simd lazy switch implementation, uses similar approach and depends on the
