But yes for v7 it might not help.The only way , from my experience, neon could be used effectively is a test/copy routine for all sizes. Most arm/arm64 libc do that. I would like to try this. But I have no Idea where to put the .s file in order to build it. I don't want to have it inline since it is quite big..
