Thanks for taking a look at the issue

Please could you remove unrelated formatting changes from the patch? It adds "noise" to reviews - typically we only format lines that are touched by the patch (git diff  -U0 | py -3 clang\tools\clang-format\clang-format-diff.py -p1 -binary "<path-to-llvm-build-dir>\bin\clang-format" -i).

> Test results: All 576 X86 DebugInfo tests pass.

As you're changing functionality, this patch will need to come with a/some new test/tests.

In the linked ticket it says

> There is one test related to prologue-end that seems to be testing that it's okay for prologue-end to be line 0, and I ran out of time to investigate any further.

Do you know which test that is? I wonder if there's any git-history which could be relevant
