            Bug ID: 27440
           Summary: [dwz, dwarf5] Add --dwarf-5 flag to generate
                    .debug_sup, ref_sup and strp_sup
           Product: dwz
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: default
          Assignee: nobody at sourceware dot org

  Target Milestone: ---

Currently the dwz multi-files are really DWARF4 + GNU extensions. Since the
format and references were formalized in the DWARF5 spec as DWARF Supplementary
Object Files (DWARF5 section 7.3.6) it would be nice to have a way to generate
this format with a --dwarf-5 flag:

- Use DW_FORM_ref_sup[48] and DW_FORM_strp_sup instead of
  DW_FORM_GNU_ref_alt and DW_FORM_GNU_strp_alt

- Generate .debug_sup section (standardized variant of .gnu_debugaltlink)
