farmhash's Issues

Add documentation on the hash algorithm

As far as I can see, there's no documentation on how the thing actually works. 
The source code is rather complex. Are there any Google-internal docs? If so, 
is there any chance of releasing them? Implementations in different languages 
would be so much easier to write...

Compiler warnings when 64-bit size_t is squashed to 32-bits

What steps will reproduce the problem?
1. Try compiling farmhash on a 64-bit Mac using Xcode 6.x

What is the expected output? What do you see instead?
I expect it to compile clean. Instead I get a ton of warnings:
farmhash.cc:995:26: Implicit conversion loses integer precision: 'size_t' (aka 
'unsigned long') to 'uint32_t' (aka 'unsigned int')

What version of the product are you using? On what operating system?
farmhash-1.1.0

Please provide any additional information below.

Not that anybody would try to hash 4+ gigabytes of data, but if they do, will 
it still work?

If you feel that losing precision is intentional, then a bunch of 
static_cast<uint32_t>(len) would do the trick.
