Hi! I'm not a contributor or maintainer of this repo! But you can try these sollutions:

• remove #[naked] in function signature
• use naked_asm! instead of asm! and remove options(no_return) line, because it don't support naked_asm!.

But be careful because it's seriously modifying the actually program behavior so it will be great if an author/contributor/maintainer will pickup this issue. The deepened knowledge of this repo may be required. I plan of creating my own OS written in Rust and running on a riscv64GC board so I'm looking at existing implementations, and I have the constant frustration of non-compiling projects :(

I hope you'll be able to fix that issue or find a workaround! (If you follow one of my two proposed steps, you still get an error, not always the same: substraction overflow or an exception from kerneltrap)

Good luck!
