e500mc is. e500v1 and v2 aren't even user-space compatible because Ruiz-era Motorola was cheap and wanted SMD w/o Altivec, so they replaced the FPU...

Both run the standard Debian powerpc port with a kernel with FPU emulation enabled.

There used to be a powerpcspe in Debian which I maintained where even Rust worked after I added target support to the Rust compiler (and one very talented FreeBSD developer improved the LLVM backend).

However, GCC upstream decided to kill off the powerpcspe port for GCC 9, so we had to drop it in Debian.

They're not user space compatible, but they're very, very similar uarchs as you can tell from the supervisor SPRs.
