If you look inside JavaScriptCore/heap/MachineStackMarker.h/cpp you<br class="">will see the code that does this. I’ve also written code that grabs PC and FP for other platforms. If you look at my WIP patch<br class="">you can see that code: <a href="https://bugs.webkit.org/show_bug.cgi?id=151713" class="">https://bugs.webkit.org/show_bug.cgi?id=151713</a>.<br class=""><br class="">I’d like to get this working on all ports before landing. Do people who maintain the gtk and efl ports<br class="">have an idea on how to do this? Or could you help me figure out a solution?<br class=""><br class="">Thanks,<br class="">Saam</body></html>
