+       * elf32-hppa.c (elf32_hppa_link_hash_table): Add text_segment_base,
+       and data_segment_base fields.
+       (elf32_hppa_link_hash_table_create ): Init them.
+       (elf32_hppa_check_relocs): Update comments.
+       (hppa_record_segment_addr): New function.
+       (elf32_hppa_relocate_section): Call it.
+       (final_link_relocate): Handle R_PARISC_SEGREL32.
+       (elf32_hppa_final_link): New function.
+       (bfd_elf32_bfd_final_link): Define to call it.
+       (hppa_unwind_entry_compare): New function.
+       * cache.c (bfd_open_file): Create files in write+read mode.
+
+       * elf-hppa.h (elf_hppa_howto_table): Set bitsize value for
+       SEGREL32 and numerous other relocs.  Change duplicate
+       R_PARISC_NONE relocs to R_PARISC_UNIMPLEMENTED.
+
        * opncls.c (bfd_fdopenr): Add parens like the comment says around
        O_ACCMODE.

+       * config/tc-hppa.c (pa_build_unwind_subspace): Use SEGREL32 for

        * config/tc-hppa.c (pa_ip): Store `a' flag in bit zero of operand
        and don't bother storing `m' for "ce" completer.  Tidy handling of
        'J' and 'K' operands to suit.  Handle '<' and '>' operands.
