Hi,
I'm trying to generate an executable riscv binary (kernel.bin) from a riscv assembly code (kernel.s).
- Using the riscv-none-embed-gcc toolchain, the binary is succesfully generated and I can run it on my device:
```sh
riscv-none-embed-as kernel.s -o kernel.o
riscv-none-embed-ld kernel.o -o kernel.elf
riscv-none-embed-objcopy -O binary kernel.elf kernel.bin
```
- But when I try to do the same process with Clang/LLVM (v17.0.5), the binary is not executed on my device:
```sh
clang -c -target riscv32 -march=rv32ia kernel.s -o kernel.elf
llvm-objcopy kernel.elf -O binary kernel.bin
```
Maybe I'm using the wrong Clang/LLVM commands, or with the wrong arguments? I see that the two .elf files are different.
Thanks !
