[Soot-list] fixing more equivTo methods...

[Michael Faes]

Hi Eric and everyone,

While messing around with the newest nightly build, I found something 
funny: The equivTo method of AbstractSpecialInvokeExpr, while looking 
very sophisticated, always returns false:

public boolean equivTo(Object o) {
   if (o instanceof AbstractSpecialInvokeExpr)
   {
     AbstractSpecialInvokeExpr ie = (AbstractSpecialInvokeExpr)o;
     if (!(baseBox.getValue().equivTo(ie.baseBox.getValue()) &&
         getMethod().equals(ie.getMethod()) &&
         argBoxes.length == ie.argBoxes.length))
       return false;
     for(int i=0; i< argBoxes.length; i++){
       if(!(argBoxes[i]).getValue().equivTo(ie.argBoxes[i].getValue()))
       return false;
     }
   }
   return false;
}

This change was made in the following commit ("fixing more equivTo 
methods"): 
https://github.com/Sable/soot/commit/0740ce06bace421870fe2cf00f7d1c3805e5f02d

I assume this is a bug. Is it possible to quickly fix this? Or should I 
just use the old version? It seemed to work for me so far...

Best regards,
Michael
