Thank you! I just posted a rather unruly (but functional) set of patches with the cover letter title of "RFC: ARM Semihosting, PMU, and BBV Changes". These changes include support for collecting block vectors, which are nothing more than accumulating instruction counts broken per block (and interval). While I would guess there are probably much better ways to implement the same functionality, perhaps it's a starting point. Christopher Covington -- Qualcomm Innovation Center, Inc.
