Alex Crichton bec7b766fb rustc: Move to FNV hashing for node/def ids ... This leverages the new hashing framework and hashmap implementation to provide a much speedier hashing algorithm for node ids and def ids. The hash algorithm used is currentl FNV hashing, but it's quite easy to swap out. I originally implemented hashing as the identity function, but this actually ended up in slowing down rustc compiling libstd from 8s to 13s. I would suspect that this is a result of a large number of collisions. With FNV hashing, we get these timings (compiling with --no-trans, in seconds): | | before | after | |-----------|---------:|--------:| | libstd | 8.324 | 6.703 | | stdtest | 47.674 | 46.857 | | libsyntax | 9.918 | 8.400 |		2014-03-06 17:45:48 -08:00
