genemit.c patch

[John Carr]

This patch allows a machine description to specifiy a mode in a split
mattern, as in this example:


(define_split
  [(set (match_operand:DI 0 "register_operand" "")
	(match_operator:DI 1 "logical_op"
			   [(match_operand:DI 2 "register_operand" "")
			    (match_operand:DI 3 "arith_double_operand" "")]))]
  "..."
  [(set (match_dup 4) (match_op_dup:SI 1 [(match_dup 6) (match_dup 8)]))
   (set (match_dup 5) (match_op_dup:SI 1 [(match_dup 7) (match_dup 9)]))]
  "...")

Without the ":SI" the mode of the operation remains DImode and the
resulting pattern is not recognized.

	* genemit.c (gen_exp): Allow machine description to set mode of
	MATCH_OP_DUP.
