    [**LoopFlatten-L787**](https://github.com/llvm/llvm-project/blob/76c8e1d8575fbeebdc0e18e0792e8f0a623834b3/llvm/lib/Transforms/Scalar/LoopFlatten.cpp#L787)

The new branch instruction created in `InnerExitingBlock` replacing the original terminator has no debug location.

```cpp
 InnerExitingBlock->getTerminator()->eraseFromParent();
->BranchInst::Create(InnerExitBlock, InnerExitingBlock);
```
