Missing comment on the predicate.
Ok, please queue this for GCC 7 with a comment adde
New patch that adds the predicate "reg_or_arm_rhs_operand" as suggested
by Richard. Tested on all arm and thumb targets as before.
Okay for trunk?

I have attached a new patch which hopefully address Richard's concerns.
I modified the predicate on operand 1 to to "arm_rhs_operand" to be
consistent with the constraints. I retained the split into two patterns;

Okay for trunk?
Hi Richard,
I think we could incorporate your feedback by changing the predicate on
operand 1 to "arm_rhs_operand" which allows "s_register_operand" or
"arm_immediate_operand". Everything else in my patch would stay the same
including splitting the thumb2 pattern out into it's own insn. I'm
