However, the situation is more complex than that. On 32bit CPUs, L=1
instructions are either treated identical to L=0 instructions (G4) or
treated as illegal instructions (e500mc). Differenciating these cases

just treat the 32bit CPU, 64bit cmp case as undefined.

Ah ha.  Interesting g4/e500 difference.
