  Log Message:
  -----------
  llvm-dwarfdump: Print warnings on invalid DWARF

llvm-dwarfdump was silent even when the format of DWARF was invalid
and/or llvm-dwarfdump did not understand/support some of the constructs.
This can be pretty confusing as llvm-dwarfdump is a tool for DWARF
producers+consumers development.
