This revision is now accepted and ready to land.

I'm not sure if we answered the original question about fast-math-flags, but that can be an independent patch if needed. This part LGTM with the dead code removed.



================
Comment at: llvm/lib/Transforms/Utils/SimplifyLibCalls.cpp:1592
 
 static Value *getPow(Value *InnerChain[33], unsigned Exp, IRBuilderBase &B) {
   // Multiplications calculated using Addition Chains.
----------------
This function is dead code now and should be removed.
