        <pre>Hi Jiangning,

I reported this issue on Friday in bug
<a class="bz_bug_link 
          bz_status_NEW "
   title="NEW --- - [AArch64] Assertion `!DefI.atEnd() && "Register has no defs"' in MachineTraceMetrics.cpp"
   href="show_bug.cgi?id=20598">http://llvm.org/bugs/show_bug.cgi?id=20598</a>.

I have noted it happens after commit r215151.

I will mark yours as a duplicate.
