 	* optabs.c (emit_conditional_add): Correct comment about the arguments.
	Remove code which might swap op2 and op3 since they cannot be swapped.
	* doc/md.texi (add@var{mode}cc): Fix document about how the arguments
	are used.

@item @samp{add@var{mode}cc}
Similar to @samp{mov@var{mode}cc} but for conditional addition. Conditionally
move operand 2 or (operands 2 + operand 3) into operand 0 according to the
comparison in operand 1. If the comparison is true, operand 2 is moved into
comparison in operand 1. If the comparison is false, operand 2 is moved into
operand 0, otherwise (operand 2 + operand 3) is moved.
