> + static bool canGoAfterDWARF(const MCSectionMachO &MSec) {
> +  // These sections are created by the assembler itself after the end of
> +  // the .s file.
> +  StringRef SegName = MSec.getSegmentName();
> +  StringRef SecName = MSec.getSectionName();
> +
> +  if (SegName == "__LD" && SecName == "__compact_unwind")
