Hello,

thank you for considering the patches

I tried to get the Orc svolume to work; this is not possible for the 
moment since Orc lacks support for loadpq on ARM NEON -- so no comparison

I have been in contact with David Schleef but no progress there
I failed to implement the missing support myself in a reasonable time

ok, will try to make use of that
