All the core tools are now also available for M1 Mac (arm64). The script https://apertium.projectjj.com/osx/install-nightly.sh is updated to fetch the correct arch. Also left a symlink to the x86_64 bundle in the old place because it'll still work thanks to Rosetta.
Speaking of, the performance of native vs. emulated is that native arm64 is 25% faster. Building giella-kal on M1 with x86_64 tools takes 775 real (889 user, 15.5 sys) seconds, but with arm64 tools it takes 598 real (664 user, 30 sys) seconds. And 16 GB RAM is definitely needed. It would've swapped with less, and I had nothing else running. With the 8 GB models I can't imagine how much it would thrash if one had some IDEs, browsers, etc, open while building a language. The only code adjustment needed was in CG-3, and wasn't even arch-portability related - was just a C++20 quirk. -- Tino Didriksen
