================
Comment at: llvm/include/llvm/Transforms/InstCombine/InstCombiner.h:492
+  bool isVScaleKnownToBeAPowerOfTwo() {
+    return TTI.isVScaleKnownToBeAPowerOfTwo();
+  }
----------------
This needs to be either a data layout property or a function attribute. Though it would probably best to change LangRef to require that vscale is //always// a power of two -- I think consensus has shifted towards non-pow2 vscales not being necessary.
