please use imperative, present tense in logs.  Also in the $subject
line when that gets into the commit log: s/Implements/Implement/.

And, updated how?  What changed?  Please write something
like:

	* arm-tdep.c (arm_record_coproc_data_proc): Handle foo instructions.

with 'foo' replaced, of course.  :-)

'Add'.

Likewise, updated how?

>>>         (decode_insn): Updated.

Say something like:
	
	(decode_insn): Install arm_record_asimd_vfp_coproc as handler for
	opcode 110 insns.

I didn't see a reply to Will's comment.  Should op1_sbit haven been used?

This patch is OK once Will is happy with it.
