    mov rcx, 0xC0FFEE
    mov rdx, 0b110000001111111111101110

    cmp rax, "Goodbye, world"
    je string_equality_true
    jne string_equality_false
    :_ret_string_equality ; the ret operator isn't supported yet

    cmp rcx, rdx
    je int64_equality_true
    jne int64_equality_false

:string_equality_true
    dmp "Strings are equal!"
    jmp _ret_string_equality

:string_equality_false
    dmp "Strings are different!"
    jmp _ret_string_equality

:int64_equality_true
    dmp "Int64 are equal :)"
    jmp end

:int64_equality_false
    dmp "Int64 are different :("
    jmp end

:end
    dmp "Bye!"
