What are you trying to accomplish with this? The SPRs are not accessible via instrumentation, which is why the BPatch registers method didn't return them.

This register patch was brought up a while ago, and I admit I still
haven't gotten around to using it. Real Soon Now (TM).
But I'd much rather have this functionality included in Dyninst, rather
than patching it ourselves. Can this be evaluated and applied please?
I mentioned before when I looked at this, I don't see much reason to
have it guarded by the includeSPRs boolean - just enumerate all
available registers all the time. But that's your call...
Thanks,
Josh

Josh,
I'm attaching the patch. It adds a boolean parameter to
BPatch_addressSpace::getRegisters that allows you to specify whether
you'd like the special-purpose registers returned in the vector along
with the standard registers. It's also online in my git repository for
CRAFT:

Hi Michael,
You mentioned to me at pdweek that you had a Dyninst patch which allowed
access to the special purpose registers on x86 (IP, SP, etc). Could you
share that patch? And I'd like to propose as well that this be added to
Dyninst proper, as we prefer not to carry extra patches when possible.
Thanks,
Josh
