[Chuanqi Xu via Phabricator via llvm-commits]

ChuanqiXu added inline comments.


================
Comment at: llvm/lib/Transforms/IPO/FunctionSpecialization.cpp:274
+    auto LoopDepth = LI.getLoopDepth(I->getParent());
+    Cost *= std::pow((double)AvgLoopIterationCount, LoopDepth);
     return Cost;
----------------
Converting to double here is to reduce the ambitious reloading.
