That's the point of the warning, an operand written as register but isn't
one.

Is there any place/document I can check that's saying %r0 can not be used in
this way?

For the second line, the second operand is not a register but the constant 0
(equivalent to lis %r5,2).

Do you mean even it is written as %r0 it is treated as constant 0?
if so in line 3, the second operand is written explicity as constant 0, why it
is OK?
