            Bug ID: 28497
           Summary: lld does not support --gdb-index option
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: ELF

gold linker supports this option:

Use the gold linker's --gdb-index option (-Wl,--gdb-index when linking with gcc
or g++) at link time to create the .gdb_index section that allows GDB to locate
and read the .dwo files as it needs them.

It is used in combination with gcc -gsplit-dwarf option to enable the
generation of split DWARF at compile time.
