--- Comment #2 from John Brawn <john.brawn.123 at gmail.com> ---
The shifted-register forms of MOV are aliases for various shift instructions.
The table in section A8.8.105 (of the ARMv7-A/R ARMARM revision C.c) does just
list the mnemonic as MOV{S}, but the intent is that the standard <c> and <q>
qualifiers are permitted - the ARMv8 ARMARM does explicitly list these
qualifiers (section F6.1.98 encoding T3).
