  Changed paths:
    M llvm/lib/DebugInfo/DWARF/DWARFDebugLine.cpp
    A llvm/test/tools/llvm-dwarfdump/X86/debug_line_short_prologue.s

  Log Message:
  -----------
  [DWARFDebugLine] Check for (EOF) errors when parsing v5 content descriptors

Summary:
Without that we could be silently reading zeroes, as that's the default
DataExtractor behavior. The entire parse would still most likely fail,
but it would do that with a seemingly unrelated/nonsensical error
message.
