We need extconf to detect which SIMD features the compiler and processor support, then we can compile in SIMD support for BLAKE3 ruby/digest@6865b37d30 Co-Authored-By: Jean Boussier <jean.boussier@gmail.com>
Instead of iterating over the bytes of the ar_table hints one by one, we can use a little bit of SWAR code to match them all at once and return the first matching byte index. In theory we could even re-use the mask to extract all matching position, however we can't do that because since `ar_equal` calls back into Ruby, the hints may change after every iteration. ``` compare-ruby: ruby 4.1.0dev (2026-08-06T14:05:57Z master 9658933) +YJIT +PRISM [arm64-darwin25] built-ruby: ruby 4.1.0dev (2026-08-06T16:42:50Z ar-find-entry-swar-2 723ff01) +YJIT +PRISM [arm64-darwin25] ``` | |compare-ruby|built-ruby| |:-----------|-----------:|---------:| |hit_first | 13.891M| 15.085M| | | -| 1.09x| |hit_third | 13.322M| 15.065M| | | -| 1.13x| |hit_fourth | 12.759M| 14.410M| | | -| 1.13x| |hit_last | 11.545M| 15.275M| | | -| 1.32x| |miss | 10.872M| 16.286M| | | -| 1.50x|
