They must be preserved.

The problem is how to compute f3(x,y,z) = (x & y) | (z & (x | y)), where x, y and z are in registers, and the result should be stored in my *only* temporary register.
That may be tricky if x, y and z all have to be preserved. (If any one of them can be overwritten, it's easy.)
