I've had a look to

https://launchpad.net/cortex-strings

and there downloaded

https://launchpad.net/cortex-strings/trunk/2013.01/+download/cortex-strings-1.0-2013.01.tar.bz2

(from the green download button on the right side).

The README mentions

src/neon  contains NEON based routines for AArch32.

but the cortex-strings-1.0-2013.01.tar.bz2 seems to contain an empty 
src/neon directory. Is this intended?

Best regards
