Hello Vadim, That sounds like fine work for improving efficiency on ARM. Pls feel free to send me a patch, perhaps including a patch for README that describes the ./configure options.
I am not very good at ./configure (autoconf/configure.in to autogen.sh/configure.ac) but I am happy to follow your lead.
