Simple AArch64 Bare Metal

• Toolchain： Arm GNU Toolchain Downloads
• About rdimon.spec: nosys nano rdimon

C code example:

#include <stdio.h>
int main() { printf("Hello world!\n"); }

Compile it with rdimon.specs:

$ aarch64-none-elf-gcc -static -specs=rdimon.specs hello.c
$ qemu-8.2.6/bin/qemu-aarch64 ./a.out

In this way, we get a bare metal executable which only require ARM semihosting support (no OS needed).
