difference of two symbols if the relocation size is 32 bits.

Useful stuff from one of the aborted attempts to fix 12912.

COFF_ADJUST_FILEHDR_IN_PRE and COFF_ADJUST_FILEHDR_IN_POST if they
are defined.
(coff_swap_filehdr_out): Invoke COFF_ADJUST_FILEHDR_OUT_PRE and
COFF_ADJUST_FILEHDR_OUT_POST if they are defined.

(coff_swap_scnhdr_out): Invoke COFF_ADJUST_SCNHDR_OUT_PRE and
COFF_ADJUST_SCNHDR_OUT_POST if they are defined.

rather than bfd.texi.
(DOCFILES): Change bfd.texi to bfdt.texi.
* bfd.texinfo: Include bfdt.texi, not bfd.texi.
target id field to TIC80_TARGET_ID.

if used.

symbol overriding an old defined symbol, return the hash table
entry which we modify, even if it is the target of an
indirection.
(elf_link_add_object_symbols): If the real name of the symbol gets
overridden, convert the versioned symbol into an indirect symbol
to the real symbol.
* elf32-ppc.c (ppc_elf_relocate_section): Don't emit R_PPC_REL*
relocs in shared libraries which refer to local symbols. Cope
with addend when processing a GOT relocation.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): Only create symbols
for sections that the linker didn't create.
(ppc_elf_finish_dynamic_sections): Only try to write out a section
symbol if it was created in ppc_elf_size_dynamic_sections.
(ppc_elf_relocate_section): Complain if we have to generate a reloc
relative to a section for which we didn't output a symbol.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): Clean up. PLT
relocs are 'rela' relocs, like everything else. .rela.plt is not
a read-only section, so we don't have to special-case it.
* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Entries in the
.rela.bss section are (of course) 'rela' relocs not 'rel' relocs.
* elf32-ppc.c (ppc_elf_check_relocs): Initialise srelgot.
(ppc_elf_relocate_section): @got offsets are 4 from start of the
actual .got section.
* elflink.c (_bfd_elf_create_got_section): The three reserved
words start from the symbol '_GLOBAL_OFFSET_TABLE_'.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): '.rela' is 5
characters, not 4.
* elf32-ppc.c (ppc_elf_check_relocs): Use
_bfd_elf_create_got_section to create the GOT rather than
ppc_elf_create_linker_section. Create the '.rela.got' section
ourselves.
(ppc_elf_finish_dynamic_symbol): Set up GOT relocations when a
symbol has a GOT entry.
(ppc_elf_relocate_section): Record when a symbol is used through
the GOT, and allocate space in the GOT for each such symbol.
(ppc_elf_adjust_dynamic_symbol): Delete unused .got.plt stuff.
(ppc_elf_create_linker_section): Delete unused LINKER_SECTION_GOT
stuff.
* elf32-ppc.c (ppc_elf_howto_raw): GOT16_HA relocs should be
treated in a similar way to ADDR16_HA relocs.
(ppc_elf_relocate_section): PLTREL24 relocs do not get copied into
shared objects; the linker must deal with them.
(ppc_elf_create_linker_section): Stop setting
_GLOBAL_OFFSET_TABLE_ to the wrong value; delete unused
LINKER_SECTION_PLT stuff.
(ppc_elf_check_relocs): Delete unused LINKER_SECTION_PLT stuff.
(ppc_elf_finish_dynamic_sections): Use BFD calls to get GOT
section, not ELF-specific calls.
(elf_backend_plt_not_loaded): Set to 1.
(elf_backend_got_symbol_offset): Set to 4.
* elf-bfd.h (elf_backend_data): Add 'plt_not_loaded' member
for when ld.so fills in the PLT; and 'got_symbol_offset' member.
* elflink.c (_bfd_elf_create_dynamic_sections): Apply
plt_not_loaded member.
(_bfd_elf_create_got_section): Apply got_symbol_offset.
* elfxx-target.h (elf_backend_plt_not_loaded): Set default to
'loaded'.
(elf_backend_G_O_T_offset): Set default to 0.
(elfNN_bed): Set added fields.
* elf32-ppc.c (ppc_elf_size_dynamic_sections): Was setting
DT_RELENT in shared objects; should be DT_RELAENT.
* elf32-ppc.c (ppc_elf_relocate_section): Propagate
R_PPC_ADDR16_HA relocs to shared objects. Cope with case where
such a reloc (in a non-shared object) refers to a symbol that's
not defined.
* elfcode.h (put_signed_word): Define.
(get_signed_word): Define.
(elf_swap_reloca_in): Use get_signed_word for the r_addend field.
(elf_swap_reloca_out): Use put_signed_word for the r_addend
field.
* elf32-m68k.c (elf_m68k_finish_dynamic_symbol): Use
bfd_get_signed_32 to set the r_addend field.
* elf64-mips.c (mips_elf64_swap_reloca_in): Use
bfd_h_get_signed_64 to set the r_addend field.
elf_link_assign_sym_version before elf_adjust_dynamic_symbol.
(elf_fix_symbol_flags): New static function, broken out of
elf_adjust_dynamic_symbol.
(elf_adjust_dynamic_symbol): Call elf_fix_symbol_flags.
(elf_link_assign_sym_version): Likewise. Permit a symbol to be
forced local even if NEEDS_PLT is set. When forcing a symbol to
be local, clear NEEDS_PLT.
(elf_link_output_extsym): Remove unused local bed.
for a symbol which is being forced to be local.
* elf32-i386.c (elf_i386_relocate_section): Write out the
relocation value for a GOT reloc for a symbol which is turning
into a local symbol.
(elf_i386_finish_dynamic_symbol): If a symbol is turning into a
local symbol, write out a RELATIVE reloc rather than a GLOB_DAT
reloc.
* elf32-m68k.c, elf32-sparc.c: Corresponding changes.
value if the symbol is turning into a local symbol.
* elf32-m68k.c (elf_m68k_relocate_section): Likewise.
* elf32-sparc.c (elf32_sparc_relocate_section): Likewise.
information by calling `_bfd_elf_slurp_version_tables'.
(elf_link_add_object_symbols): For undefined symbols look for
version informaiton in the verneed records.
(elf_link_add_object_symbols): Use soname of shared object
for verneed record if it is available.
for a section even if it is not loaded.
Otherwise compiling this
static char bar; char *foo() { return &bar; }

(_bfd_coff_link_input_bfd): Separate section VMA handling for
input and output files.
(_bfd_coff_generic_relocate_section): Check whether input file,
not output file, is a PE file.
