Assembly (GAS, ARM, Linux, no libc), score: 7, safe

Textual assembly, not machine code.

This makes it so you can't use bx, bl blx, push, pop, svc, swi, str, stm, syscall, mrs, or any assembler directives. Good luck trying to run a syscall or switch to Thumb. 😈

You can assume your code is placed under this exact header, so don't worry about declaring the function.

        .text
        .arch armv5te
        .arm
        .globl _start
_start:

Should be pretty easy for those who are familiar with ARM's assembler. 🙂

My solution I can't get code blocks to work properly in spoilers, so here's a GitHub gist.
