deagwon97/riscv-gnu-toolchain repository overview

⁠riscv-gnu-toolchain

This is "riscv gnu toolchain" container image. It has tags corresponding to both the arm64(apple silicon) and amd64(intel, amd) architectures.

You could cross-compile your C code to RISC-V binary. Use the appropriate tag depending on the device you are using.

⁠How to use

⁠1. docker run

>> docker run -it deagwon97/riscv-gnu-toolchain:amd64 # for intel, amd
or
>> docker run -it deagwon97/riscv-gnu-toolchain:arm64 # for apple silicon

⁠2. create example code

# root@776c53f76757:~# cat << EOF > main.c
> long A[10] = { -1, -2, -3, 1, 2, 3, 4, 5, 6, 7 };
> long sum = 0;
> int i;
>
> int main (void) {
>    for (i=0; i<10; i++) {
>       if (A[i]>0)
>          sum += A[i];
>    }
>    return 0;
> }
>
> EOF
# root@776c53f76757:~# ls
main.c

⁠3. compile main.c by riscv64-unknown-elf-gcc

# root@776c53f76757:~# riscv64-unknown-elf-gcc main.c -o main.out
# root@776c53f76757:~# ls
main.c  main.out

⁠4. disassemble main.out by riscv64-unknown-elf-objdump

root@776c53f76757:~# riscv64-unknown-elf-objdump --disassemble=main --visualize-jumps --disassembler-color=extended -M numeric,no-aliases main.out

main.out:     file format elf64-littleriscv
