...h_combine may still produce different results if the size of an argument type differs between platforms). I suspect the negative performance impact on 32-bit platforms should be small, but I didn't do any benchmarking. With atomics one could probably replace the thread safe local static in get_execution_seed with something that has a little less overhead. The patch also removes a FIXME from the set_fixed_execution_seed implementation and rewords the documentation string a bit, since using this function in a multi-threaded program requires some kind of external synchronization anyway. Another attac...

Does the enclosed implementation implement this part of N3333: http://www.open-std.org/Jtc1/sc22/wg21/docs/papers/2012/n3333.html#per.process.seed ? That to me seems like potentially the most

Hi, Currently the hashing implementation in ADT/Hashing.h produces hash values on 32-bit platforms that differ from the lower 32-bits of the hash values produced on 64-bit platforms. It seems the only reason for this difference is that the uint64_t integer seed is truncated to size_t. Since the usage of uint64_t and size_t as types for seed values in the implementation is somewhat

Hello folks, TL;DR: This is my proposed hashing interface based on a proposed standard hashing interface. It also is implemented with a much faster and higher quality algorithm than the current one. This is an *early draft* of the code, looking for initial feedback. There has been recent interest in improving the quality and consistency of LLVM's approach to hashing. In particular, getting
