[PATCH] D69606: [MachineBasicBlock] Skip over debug instructions in computeRegisterLiveness before checking for begin/end.

[Chris Ye via Phabricator via llvm-commits]

yechunliang added inline comments.


================
Comment at: llvm/lib/CodeGen/MachineBasicBlock.cpp:1410-1411
+  // Skip over debug instructions.
+  if (I != end() && I->isDebugInstr())
+    ++I;
+
----------------
Does this code duplicated with the line: 1392-1394?

```
 for (; I != end() && N > 0; ++I) {
    if (I->isDebugInstr())
      continue;
```
