Patch 2 doesn't handle DW_AT_GNU_addr_base, DW_FORM_GNU_addr_index and DW_FORM_GNU_str_index. But those are only used as extensions to DWARF4 with split-dwarf. Support could be added later if people really use pre-DWARF5 split-dwarf.

setup_cu_bases could check for cc->version >= 5 to prevent some work for older DWARF, but it is probably not noticeable.

Looks good. Pushed as:

    read dwarf5 DW_FORM_addrx* and DW_FORM_strx* as generated by Clang14

    DW_FORM_addrx* are offsets into .debug_addr containing addresses.
    DW_FORM_strx* are offsets into .debug_str_offsets, which contain
    offsets into .debug_str. Support for these also requires reading
    DW_AT_addr_base and DW_AT_str_offsets_base before any other field
    in the abbrev table entry, as those may use this form.
