[PATCH] D70240: [ARM][ReachingDefs] Remove dead code in loloops.

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer added inline comments.


================
Comment at: llvm/lib/CodeGen/ReachingDefAnalysis.cpp:234
+ 
+      if (getReachingMIDef(&*MI, PhysReg) != Def)
+        return;
----------------
Just a quick question on this. 
At this point, I think we have found an instruction that defines PhysReg, so I was looking into why we need to call getReachingMIDef , but perhaps you can help me, and/or place a comment if you think that is useful.
