You may need to downgrade rustc. I'll try adapting and testing this on latest rustc.

I have fixed the compile error of rustc in https://github.com/skyzh/core-os-riscv/pull/12. However, we are still blocked by https://github.com/rust-embedded/riscv/issues/69, where riscv would produce wrong float abi and would cause link error later.

If you really want to play with core-os-riscv, the best way to do for now is to use a nightly toolchain published in 2020.
