<div>
<pre>StackProtector::HasAddressTaken has a whitelist of instructions that may
capture, and it is out of date. It assumes anything it doesn't know about
doesn't capture. Since this ancient pass was added, AddrSpaceCast and
AtomicCmpXChg have been added as new potential captures. This should use
CaptureTracking instead of maintaining its own capture detection</pre>
