That would be in the trace sent to the callback. We could add something like the '?' if it's not trusted. But for now, until we have a use case that we are implementing, I want to keep this simple, otherwise it will never get done. I don't want to add features for hypothetical scenarios. Currently, the traceback is just an array of addresses. But this could change in the future. What we are discussing right now is the internal functionality of the user unwind code where I have made most of theses functions static. The only external functions that get called during the iteration is the architecture specific code. If that code needs to know the difference between sframes and frame pointers then we can modify it, but until then, I rather keep this as is. Jens, is there something that the architecture code needs now? If so, then lets fix it, otherwise lets do it when there is something. This isn't user API, it can change in the future. -- Steve
