static bool updateOperand	(	Instruction *	Inst,
		unsigned	Idx,
		Instruction *	Mat
	)		[static]

Updates the operand at Idx in instruction Inst with the result of instruction Mat. If the instruction is a PHI node then special handling for duplicate values form the same incomming basic block is required.

Returns:

The update will always succeed, but the return value indicated if Mat was used for the update or not.
