================
Comment at: llvm/lib/Transforms/Utils/LoopUtils.cpp:1257-1259
+  if (!InductionDescriptor::isInductionPHI(Phi, L, SE, ID))
+    return false;
+  return true;
----------------
could these three statements simply be:
```
return InductionDescriptor::isInductionPHI(Phi, L, SE, ID));
```
?
