In the past, it has taken about 3 wizard-months to port CCL to a new architecture. People not as wizardly as gb was would take somewhat longer.

I was basically new to the system back when I ported it to 32-bit x86, and that took me about 3 months or a bit more. I was able to take advantage of a lot of the existing 64-bit x86 port, too.

It’s a fair amount of work (and an awful lot of staring at a debugger prompt, trying to get enough of the system working to cons a hash-table, which is a major milestone), but it’s not impossible.
