Well, we probably do not check the same ARM manual, because mine allows
adds with two arguments. Anyway, you can try to fix the assembly. I
guess you can repeat the first argument before each add. Otherwise, I
can send you a .o, which I will ask you to disassemble to know what your
version of binutils wants.
