            Bug ID: 29385
           Summary: [gdb, debug-types, debug-names, dwarf-5] Support
                    .debug_names section with TUs in .debug_info
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: symtab
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

[ spin-off of PR29381. ]

When running the test-case gdb.cp/cpexprs-debug-types.exp with target board
cc-with-debug-names on a system which defaults to dwarf5, gdb rejects the
.debug_names index because it cannot find a .debug_types section:
...
The .debug_names index is rejected in dwarf2_read_debug_names because:
...
  if (map->tu_count !=3D 0)
    {
      /* We can only handle a single .debug_types when we have an
         index.  */
      if (per_bfd->types.size () !=3D 1)
        return false;
...

The .debug_types section was eliminated in dwarf 5.
