            Bug ID: 30838
           Summary: [gdb/symtab] Support .debug_types section in
                    .gnu_debugaltlink file
           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: ---

There are two methods to factor out type information in a dwarf4 executable:
- use -fdebug-info-types to generate type units in a .debug_types section, and
- use dwz to create partial units.

The dwz method has an extra benefit: it also allows to factor out information
between executables into a newly created .dwz file, pointed to by a
.gnu_debugaltlink section.

There is nothing prohibiting a .gnu_debugaltlink file to contain a
.debug_types section.

It's just not generated by dwz atm, and consequently gdb has no support for it.
