================
Comment at: test/Transforms/LoopDeletion/no-sideeffect-call.ll:26
+if.then:
+  %call = call float @sqrtf(float %x) #0
+  br label %if.end
----------------
mayHaveSideEffects isn't returning the expected result on your testcase because this call isn't marked nounwind.  (I suspect your patch isn't actually doing anything useful.)
