I didn't know about that, thanks! It gives me hope that the final goal (fat binary, native ARM and native x64, all platforms on both architectures) is within reach. It looks like there are still some hiccups (the APE loader on M1) but they are much further along than I thought they were. Excellent!
Speaking about fat binaries; @jart posted this a day ago in the #ape channel on project discord:
Just created my first ever fat ape executable. I ran `apelink.com -o fat-ape-binary.com o/tiny/examples/hello2.com.dbg o/aarch64-tiny/examples/hello2.com.dbg` to create an executable that runs on Linux+OpenBSD+NetBSD+FreeBSD on x86_64+aarch64.
