Jan, I'm converting the call graph builder code for tuples and in the process I ran into calls to lang_hooks.callgraph.analyze_expr(). From what I've seen:
1- The third argument to that function (DECL), is not used by any callback. 2- In fact, if it was used, we'd ICE because the function signature expects a tree and we are calling it with a callgraph node. I'm tempted to just delete the argument. Unless you have a future use for it? Thanks.
