	    H.J. Lu  <hongjiu.lu@intel.com>

	PR gas/2117
	* config/tc-ia64.c (parse_operand): Use expression rather than
	expression_and_evalute.
	(parse_operand_and_eval): New function.  Replace all uses of
	parse_operand outside of parse_operands with this function.
	(parse_operans_maybe_eval): New function.  Replace uses of
	parse_operand in parse_operands, except for the dummy, with
	this function.
