Good patch, I am commenting here as other or more discussions may be better here. I wonder if either JIT could be used for the intrinsics support, adding neon, sse[2-4.2] or avc256/512 (the latter would basically allow most common strings to be converted in one go. If not, maybe split implementation however runtime cpu support would be better. Many distributions built with SSE2 flags but are actually ran on much recent CPUs, same for ARM (ie. graviton/neon f.e.). Thoughts? Maybe Dmitry has a better idea :) Best, -- Pierre @pierrejoye | http://www.libgd.org -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
