+ # The v8.1M MVE shift insns overlap in encoding with MOVS/ORRS
+ # and are distinguished by having Rm==13 or 15. Those are UNPREDICTABLE
+ # cases for MOVS/ORRS. We decode the MVE cases first, ensuring that
+ # they explicitly call unallocated_encoding() for cases that must UNDEF
+ # (eg "using a new shift insn on a v8.1M CPU without MVE"), and letting
+ # the rest fall through (where ORR_rrri and MOV_rxri will end up
+ # handling them as r13 and r15 accesses with the same semantics as A32).
