示例1: statement
//-------------------------------------------------------------------------
//Function statement implements the rule
//statement -> WHILE expression DO statement
// whilebegin:
// expression
// fjp "whileend"
// body_statement
// ujp "whilebegin"
// whileend:
//-------------------------------------------------------------------------
List<Exp*>* statement(Exp* expression,List<Exp*>* body_statement)
{ PCode* P;
Exp* E;
string whilebegin=L.New(); //Create whilebegin label
string whileend=L.New(); //Create whileend label
P=new PCode(whilebegin,"","","");
E=new Exp(ST.TVoid(),P);
List<Exp*>* WS=new List<Exp*>;
WS->Insert(E); //Insert whilebegin label
P=new PCode("","fjp","",whileend);
E=new Exp(expression,0,ST.TVoid(),P);
WS->Insert(E); //Insert while-test expression and false-jump
WS->Append(body_statement); //Append the while-body-statement
P=new PCode("","ujp","",whilebegin);
E=new Exp(ST.TVoid(),P);
WS->Insert(E); //Insert unconditional jump to while-test
P=new PCode(whileend,"","","");
E=new Exp(ST.TVoid(),P);
WS->Insert(E); //Insert whileend label
WS->Print(tfs);
return WS;
