How to quickly count bits in a series of ints?

http://stackoverflow.com/questions/7793997/how-to-quickly-count-bits-in-a-series-of-ints

with some clever assembler uint bit_counter 64 void Count uint64 bits bit_counter 0 bits 0 1 bit_counter 1 bits 1 1 .. bit_counter.. do 8 at once by taking 8 bits spaced 8 apart and keeping 8 uint64's for the counts. That's only 1 byte per single counter though..
