2 There are 8 registers available for arithmetic operations (r0-r7)
3 r7 is the frame pointer, and r0-r3 are used to pass arguments.
4 Combine was extending the lives of the arguments (in r0-r3) up until the
5 call to z. This leaves only 3 regs free which isn't enough to preform the
6 doubleword addition. */
