Ok, I have found a way, thanks to the c-- interpreter (here if someone
needs it http://www.antlr.org/share/1178224532340/cminus.zip).
It works pretty well, but isn't the old v2 syntax more concise?

^(IF condition .)
        {
          if ($condition.value) {
          CommonTree ifStmt = (CommonTree)$stat.start.getChild(1);
          stream.push(stream.getNodeIndex(ifStmt));
          stat();
          stream.pop();
          }
         }
