[ri4pp:2005] - Ima li leka? (ponovo) by Pesic Ivan <pekic@yubc.net>

Nesto malo pre nije bilo u redu...

Javlja mi se shift/reduce konflikt na neobicnom mestu i nema sanse da ga
razresim:
.
.
.
Type ::= IDENT:id  {: RESULT = id; :};

rhs ::= NUMBER:n {: RESULT = n; :} |  CHARCONST:c {: RESULT = c; :} ;

ConstDecl ::= FINAL Type:t IDENT:id EQUAL rhs:val
 {: if(((String)t).equals("int"))
     RESULT = new Obj(Obj.Con, id, Tab.intType);
    else
     if(((String)t).equals("char"))
      RESULT = new Obj(Obj.Con, id, Tab.charType);
     else
      System.out.println("Greska u deklaraciji konstante!");
 :} ;
.
.
.

Inace sam pokusao sa savetima sa sajta, ali ne vredi. Ionako za Type
imam samo jednu smenu, pa nemam pojma otkud konflikt.

Ima li neko neki dobar savet?
