/*

* Grab the register values as they are now.
|
|
* This won't do a particularly good job because we really
|
|
* want our caller's caller's registers, and our caller has
|
|
* already executed its prologue.
|
|
* ToDo: We could reach back into the caller's save area to do
|
|
* a better job of representing the caller's state (note that
|
|
* that will be different for 32-bit and 64-bit, because of the
|
|
* different ABIs, though).
