That is actually a pretty ugly version of word-at-a-time strlen here is my version: http://sprunge.us/VZFF http://sprunge.us/VZFF. Compilers can (and do) vector

That is actually a pretty ugly version of word-at-a-time strlen here is my version: http://sprunge.us/VZFF http://sprunge.us/VZFF. Compilers can (and do) vectorize char-at-a-time functions, ICC especially does some weird magic.

The first for-loop looks like it only stops if s* is zero or the pointer s is zero. Also you need to calculate size from the byte in the word that is zero, not the word itself.
