Hi,

Bfd is throwing errors for programs compiled with -gsplit-dwarf with clang and dwarf-5.  Made the code changes skipping DWO_id while reading debug_info header. Can you review the code changes and send in your comments/suggestions?

Inline Patch:


Skip dwo_id for split dwarf.
* dwarf2.c (parse_comp_unit): Skip DWO_id for DW_UT_skeleton.
