For the time being, you also need to check that the current toolchain is clang-19 or higher and the arch is aarch64/x86_64. GCC doesn't support this.
Btw, not sure why Aarch64-linux-gnu is failing. It's using gcc but I was under the impression that had clang support. That's a separate thing altogether though.

I think we use gcc when we cross-compile — #484 tracks switching to native runners so we can use clang and PGO.

(there was some confusion about this in #484 (comment) so we'll see..)

LGTM, to my untrained eye at least.

If you want a quick and dirty test that it's doing something for performance. Try running alpha4 vs alpha5 on this short pystones benchmark script. I got a 25% speedup or so on my computer https://gist.github.com/Fidget-Spinner/e7bf204bf605680b0fc1540fe3777acf |
