# A .gnu_debuglink section whose file name is empty or not NUL-terminated is
# not a debug link. `llvm-objcopy --only-keep-debug` leaves an empty one when it
# runs on a binary that already has a debug link.

# RUN: yaml2obj --docnum=1 %s -o %t.empty
# RUN: lldb-test object-file %t.empty | FileCheck %s
# RUN: yaml2obj --docnum=2 %s -o %t.unterminated
# RUN: lldb-test object-file %t.unterminated | FileCheck %s

# CHECK: Plugin name: pe-coff
