Whoops.  Fixed thusly:

2014-11-20  Richard Earnshaw  <rearnsha@arm.com>

	* config/tc-aarch64.c (warn_unpredictable_ldst): Check that transfer
	registers are in the GP register set.  Adjust warnings.  Use correct
	field member for address register.
	* testsuite/gas/aarch64/diagnostic.l: Update.


Thanks for the fixup Richard. Sorry about the breakage.

Regards,

Ryan Mansfield
