 912         (elf32_frv_relocate_section): Compute gprel_segment, and use it
 913         for GPREL relocs.  When linking relocatable FDPIC executables,

 923         computation of addends from section and global or local symbol
 924         value.  Change return type to bfd_boolean, and return a failure if
 925         a dynamic FUNCDESC or FUNCDESC_VALUE relocation that requires a
 926         nonzero addend is required.
 927         (elf32_frv_relocate_section): Likewise.  Print error for

 941         improve some ugly conditions.
 942         (elf32_frv_relocate_section): Likewise.  Reject inter-segment
 943         relocations in fdpic.
 944         (_frv_create_got_section): Create .rofixup.got section.
 945         (struct _frv_dynamic_got_info): Added fixups.
 946         (_frv_count_got_plt_entries): Account in-GOT relocations into
 947         relocs32, relocsfd and relocsfdv.  Account them into relocs or

 949         (elf32_frv_size_dynamic_sections): Size rofixup section.  Simplify
 950         sizing of gotrel.

 954         relocsfdv.
 955         * elf32-frv.c (FRV_SYM_LOCAL): New macro, used instead of
 956         SYMBOL_CALLS_LOCAL and SYMBOL_REFERENCES_LOCAL.
 957         (FRV_FUNCDESC_LOCAL): New macro, used to decide whether a function
 958         descriptor of a (formerly-)global symbol is local.

 964         symbol's value to addend in the common preamble.  Decay dynamic
 965         symbols to section+offset if they bind or call locally, for GOT
 966         and FUNCDESC_VALUE, respectively.
 967         (elf32_frv_relocate_section): Likewise.
 968         (elf32_frv_check_relocs): Don't register as dynamic symbols of

 971         * elf32-frv.c (_frv_emit_got_relocs_plt_entries): Get addend as
 972         argument, so as to not call _bfd_elf_rel_local_sym to compute it.
 973         (elf32_frv_relocate_section): Pass relocation addend in.  Use
 974         original relocation addend to look up the got relocs/plt entries
 975         table.  Do not call _bfd_elf_rel_local_sym.  Don't error out when
 976         processing relocations that reference .scommon symbols.
