Using the RISC-V toolchain

The toolchain is installed in Cloud Ubuntu VM.

Creating a “Hello World” program:

tatarnikov@akos:~/hello$ cat hello.c
#include <stdio.h>
int main() {
  printf("Hello World!\n");
  return 0;
}

Compiling a C program to RISC-V executable:

tatarnikov@akos:~/hello$ riscv64-unknown-linux-gnu-gcc hello.c -o hello -static

Compiling a C program to RISC-V assembly:

tatarnikov@akos:~/hello$ riscv64-unknown-linux-gnu-gcc hello.c -S

Assembling and linking a RISC-V assembly program to executable:

tatarnikov@akos:~/hello$ riscv64-unknown-linux-gnu-gcc hello.s -o hello -static

Disassembling a compiled executable file:

tatarnikov@akos:~/hello$ riscv64-unknown-linux-gnu-objdump hello -S

Running the compiled program with the Spike RISC-V simulator:

tatarnikov@akos:~/hello$ spike $RISCV/riscv64-unknown-linux-gnu/bin/pk hello
bbl loader
Hello, world!
