I committed the 128 bit version to arm/neon, making it become used for
all Neon capable processors. I put it there since it is a speedup for
A9 as

I did both a 128-bit aligned version,
$ ./speed-128 -p 10 -C -s 10,50,100,500,1000,5000,1 mpn_and_n
mpn_nand_n
clock_gettime is 1.000ns accurate
overhead 6.00 cycles, precision

Yes.
My guess for the jaggyness is that of two src ptrs, you rarely strike
a case where they are 256-bit aligned, in particular not when
