I don't see any obvious problem here. I am not familiar with rust. Is `riscv32i-unknown-none-elf` a valid target for `rustc`, it should be something like `riscv32-unknown-elf` in LLVM I think. And is `target-feature=+e,+c` the right way to specify features? Can you please provide the whole command/arguments passed to LLVM?
