Hello, I have to add a data structure to cgraph_node structure. My data structure is a pointer to tree node. If I add tree* abc to cgraph_node, I get an error 'field `(*x).abc' is pointer to unimplemented type' Does this mean that I cannot add pointer-to pointer data structures to cgraph_node? If anyone faced a similar problem, any suggested workaround to alleviate this issue? Thanks!
