Djordje Todorovic 1e88deac13 [Debugify][OriginalDIMode] Export the report into JSON file
By using the original-di check with debugify in the combination with
the llvm/utils/llvm-original-di-preservation.py it becomes very user
friendly tool. An example of the HTML page with the issues
related to debug info can be found at [0].
