Jean Boussier 9e9f1d9301 Precompute embedded string literals hash code ... With embedded strings we often have some space left in the slot, which we can use to store the string Hash code. It's probably only worth it for string literals, as they are the ones likely to be used as hash keys. We chose to store the Hash code right after the string terminator as to make it easy/fast to compute, and not require one more union in RString. ``` compare-ruby: ruby 3.4.0dev (2024-04-22T06:32:21Z main f77618c1fa) [arm64-darwin23] built-ruby: ruby 3.4.0dev (2024-04-22T10:13:03Z interned-string-ha.. 8a1a32331b) [arm64-darwin23] last_commit=Precompute embedded string literals hash code | |compare-ruby|built-ruby| |:-----------|-----------:|---------:| |symbol | 39.275M| 39.753M| | | -| 1.01x| |dyn_symbol | 37.348M| 37.704M| | | -| 1.01x| |small_lit | 29.514M| 33.948M| | | -| 1.15x| |frozen_lit | 27.180M| 33.056M| | | -| 1.22x| |iseq_lit | 27.391M| 32.242M| | | -| 1.18x| ``` Co-Authored-By: Étienne Barrié <etienne.barrie@gmail.com>		2024-05-28 07:32:41 +02:00
