Sami might be the best person to answer this, but KCFI (not CFI) tests are lowered by passes that are architecture specific (see https://reviews.llvm.org/D119296), so we'd need to add support for RISC-V. There is no additional work required in the Rust compiler besides enabling it for the new target.

Thanks a lot Ramon!

Then for RISC-V let's go for the `depends on` for the moment, and we
can remove when the support lands for RISC-V (ideally when someone has
managed to boot it at least under some configuration).

Cheers,
Miguel
