	;movgen expects entries for at least two operands on eop stack.
	;Phase D has made one entry for the condition-name. This has
	;to be moved down in eoptab so the source operand can be build first,
	;and it has to be modified to be a datab operand, not a contab operand.
	;First, compute the size of the contab operand and move it.
