Yeah I will by the end of the week. I wrote that a few years ago so I need
to take some time to get back in the context.

BTW, that's quite a huge speed improvement you're bringing in, are you
sure you are always allowed to read up to filter[3]?

Last thing: this same optimization was also written for arm following the
same pattern. You may want to adjust that one as well while waiting for my
review :)
