Port sbcl to ppc64el

[Fernando Seiti Furusato]

Hello.
Currently, SBCL does not support ppc64le. I was not able to build it either.
It would need to be bootstrapped which does not seem to be very simple.
Would it be possible to port it to linux on ppc64le?

Thanks and regards.

Bootstrapping is the easy part. But we don't have a ppc64 backend to bootstrap to. Fortunately, ppc64 shares the same instruction encoding (at least from my cursory research) as ppc32. So it wouldn't need a new backend from scratch, just the existing one would have to respect different word widths. Which is tedious, but much easier than a new port.

Among other options, it is possible to request ppc64 vms to use:

Also, please consider the fact that, unlike big endian, ppc64 little
endian uses ABI ELFv2.

SBCL doesn't deal with ELF directly, GCC does that job.
I'm using the GCC compiler farm for ppc64le linux.

Any word on this?

No. There's no work being done and no plans to do any.
