Arc is a toy operating system for modern PCs with amd64 processors. It is written mostly in C11, with small amounts of Intel-style assembly where required. It can be loaded by any Multiboot 2-compliant boot loader, such as GNU GRUB.
The current set of features, at a high level, is roughly:
Currently these are enough to boot up and execute some simple programs written in assembly language that directly make system calls to the kernel (there’s no C library yet!)
For example, the following ‘Hello, world!’ program can be seen running in the screenshot at the top of the page:
[section .text] [global _start] _start: ; sys_trace mov rax, 0 mov rdi, hello_str syscall ; sys_exit mov rax, 1 syscall jmp $ [section .data] hello_str: db "hello, world" db 33, 10, 0
Arc is open-source software available under the terms of the ISC license, which
is similar to the 2-clause BSD license. The source code is hosted on
