[Adrian Prantl via Phabricator via llvm-commits]

aprantl added a comment.

a testcase would be nice, but generally this looks fine.



================
Comment at: include/llvm/CodeGen/SlotIndexes.h:416
       // Instructions inside a bundle have the same number as the bundle itself.
-      const MachineInstr &BundleStart = *getBundleStart(MI.getIterator());
-      assert(!BundleStart.isDebugInstr() &&
+      MachineBasicBlock::const_iterator BundleStart = getBundleStart(
+                                                          MI.getIterator());
----------------
please clang-format your patch.

Does `auto` work here? It might make the code easier to read.
