I commented on this already in various other places. NEON only offers
32-bit non-IEEE floats, so it's only applicable with manual tweaking
(even auto-vectorization at -O3 wouldn't use it due to the non-IEEE nature).
I don't think it's worth making the switch, even if we could somehow
verify that it wouldn't impact board support.
Thanks,
