示例1: solveMatch
void Operands::solveMatch(struct s_match m, struct s_operand *op, Labels labels, struct s_status *status)
{
op->name = m.element;
op->operation = m.operation;
op->aritOperand = m.operand;
op->aritOperandType = TYPE_NONE;
op->type = TYPE_LABEL;
// if the operand is a label
if((m.subtype[TYPE_ADDRESS] || m.subtype[TYPE_LABEL]) && labels.exists(op->name))
op->value = Number::toBin(labels.value(op->name));
// if not, it might be a number
else if (Number::exists(op->name))
op->value == Number::toBin(op->name);
else
throw(eUndefinedLabel);
// checks if there is an operation
if(op->operation.compare("") != 0)
Operands::solveOperation(op, labels, status);
