[Openmcl-devel] CCL on Big Sur and Apple M1 chips

[Gary Palter]

I have good news and bad news …

First, the good news — My M1 mini arrived early!

Now, the bad news — CCL does not work under Rosetta. Rosetta terminates CCL complaining about our use of the INT instruction. We use that instructions to communicate between Lisp and the kernel.

I will now try to figure out if this can be fixed.

However, as a prototype, it has hardware limitations which prevent CCL from running under Rosetta. Apple claims that those limitations do not exist in the shipping systems. But, of course, we’ll find out once I get my machine.
