example of a cheap print function

_print_foo:
    mov rdx, rsi    ; move size argument into rcx
    mov rsi, rdi    ; move the the text pointer to rsi for printing
    mov rax, 0x1    ; write stuff to stdout
    mov rdi, rax
    syscall
    xor rax, rax    ; return 0
    xor rdi, rdi
    ret

; void print_foo(const char* text, unsigned int size);
