runtime: a better fallback hash 2014-12-22T22:41:01+00:00 Keith Randall khr@golang.org 2014-12-11T01:02:58+00:00 cda0ea1c0e06d1309f66423a8fd72e272d089b6c For arm and powerpc, as well as x86 without aes instructions. Contains a mixture of ideas from cityhash and xxhash. Compared to our old fallback on ARM, it's ~no slower on small objects and up to ~50% faster on large objects.

Contains a mixture of ideas from cityhash and xxhash.

Compared to our old fallback on ARM, it's ~no slower on
small objects and up to ~50% faster on large objects.  More
importantly, it is a much better hash function and thus has
less chance of bad behavior.

Fixes #8737
