[Evandro Menezes via Phabricator via llvm-commits]

evandro added inline comments.


================
Comment at: lib/Transforms/Utils/SimplifyLibCalls.cpp:1355
+    if (Ty->isFloatTy())
+      Log = ConstantFP::get(Ty, std::log(BaseF->convertToFloat()));
+    else if (Ty->isDoubleTy())
----------------
Shouldn't this call and the one below be to `log2()`?
