* config/tc-ppc.h (tc_fix_adjustable): Don't let the assembler
calculate relocations to any external symbol, because we might be
linking a shared object and the symbol might be overriden or moved
(for instance, moved into a static executable's .bss section).
(GLOBAL_OFFSET_TABLE_NAME): Delete. This is an i386 wierdness.
* config/tc-ppc.h (tc_fix_adjustable): GOT-based relocations can't
be calculated by the assembler.
* config/tc-ppc.c (md_apply_fix3): Handle @plt or @local branch
whose destination lies in the same file, by ignoring the @plt or
@local and aiming the branch at its destination.
* 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.
signed operand, sign extend a 32 bit value to the host size.
Permits dubious usage like
addi %r6,%r6,0xfffffeff
to assemble on a 64 bit host as it does on a 32 bit host.
* 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.
cygwin32.
* Makefile.in (LD): New variable.
(EXTRA_HOST_FLAGS): Pass down LD.
($(DO_X)): Likewise.

* Makefile.in (INSTALL): Use $(SHELL) when executing install-sh.
Add missing return statements after finding an "add imm{16,32},sp"
instruction.
(mn10300_frame_chain): Add in size of our register save area to find
our caller's frame if our caller does not have a frame pointer.
Fixes some problems debugging optimized code.
(def_exports): Add data parameter. Change all callers.
(dump_def_info): Print data field.
(gen_def_file): Likewise.
(make_one_lib_file): Handle data field by not emitting simple
label and not emitting anything in SEC_TEXT.
(dtab): Print data field.
(process_duplicates): Merge data field.
* dlltool.h (def_exports): Update declaration.
* defparse.y (expline): Accept opt_DATA. Pass it to def_exports.
(opt_DATA): New non-terminal.
* deflex.l: Include dlltool.h and libiberty.h. Don't declare
strdup. Use xstrdup rather than strdup.
* defparse.y: Include bfd.h, bucomm.h, and dlltool.h.
* dlltool.c: Include dlltool.h and time.h. Make a lot of
variables and functions static. Make a lot of char * variables
and parameters const. Add declarations for static functions. Do
some reindenting. Hide more PowerPC stuff inside DLLTOOL_PPC.
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.
