--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---


On the output side:
#ifdef HAVE_ZSTD_H
  lto_compression compression = ZSTD;
#else
  lto_compression compression = ZLIB;
#endif

  bool slim_object = flag_generate_lto && !flag_fat_lto_objects;
  lto_section s
    = { LTO_major_version, LTO_minor_version, slim_object, 0, 0 };
  s.set_compression (compression);

(flags of lto_section is just set to compression)


On the input side:
Wait this should not happen.

      lto_end_uncompression (stream,
                             file_data->lto_section_header.get_compression ());
