In other contexts you'd have to jump through some hoops to find it as local 0 and even then we might not consider it to be live so you might not be able to find it.  You'd have to use some code like the vframeStream or vframeArray logic to find the root method on the compiled method and look at local 0.
Thanks, Tom

In my case, it is inside the callee that I need to get its receiver. What if
the current method is guaranteed not to be inlined? Can I find the receiver
by directly looking at the callee's local 0, instead of walking vframes?
