[LLVMdev] DSGraph questions

[Xiaodong Li]

1. What is the difference between DSNodeHandle and DSNode? What do the
functions getLink() and getSize() do?

2. In the previous email, you mentioned that we can use
DSNode::getPointerSize() to get the number of links, But I checked the
doxygen documentation, there is no such member for DSNode.

3. Previously I use the following code:
for( df_iterator<DSNode*> I = df_begin(pnode), E=df_end(pnode); I!=E; ++i)
{
  ...           ;
}
and got lots of error messages when I compile. And the reply was:
>What is the type of pnode?  Guessing from the error message, I would think
>it's a 'const DSNode*'.  You need to use either df_iterator<const DSNode*>
>or a DSNode* argument, you can't mix them.

I checked and found out that I was using
DSNode *pnode = dsg->getNodeforValue(fi).getNode() to get pnode.
So I think it's a DSNode.

Would you please answer these questions? Thanks,
Jerry
