Looks very reasonable to me.



================
Comment at: lib/Target/ARM/ARMTargetTransformInfo.cpp:815
+      case Intrinsic::loop_decrement_reg:
+        LLVM_DEBUG(dbgs() << "Found intrinsic.\n");
+        return true;
----------------
nitpick: perhaps "found hwloop intrinsic"


================
Comment at: test/Transforms/HardwareLoops/ARM/structure.ll:138
+
+; Function Attrs: noduplicate nounwind
+declare void @llvm.set.loop.iterations.i32(i32) #0
----------------
another nit: don't need the comments
