Hi Honza, Regarding modern hash functions, as far as I understand the trend is to just stop doing anything fancy and just use the CRC instructions in modern CPUs (unless you need a somewhat cryto hash to guard against DoS attacks). spooky doesn't do that though, it's just a highly optimized classical hash. It's much more stream lined than the somewhat weird iterative hash construction that standard gcc uses, and I suspect has better avalance effect. Also it'll do much less work per bit (at the cost of larger code)

I sent you the spooky patches in separate mail. I did a quick test run and they don't seem to regress anything. -Andi
