complicated tests for unresolvable relocs with a simple direct
scheme using "unresolved_reloc" var. Report some detail on
bfd_reloc_outofrange and similar errors.

ELF_LINK_NON_GOT_REF from weakdef.
(elf_s390_copy_indirect_symbol): Test whether the weakdef sym has
already been adjusted before treating it specially.

non-default visibility, a) don't make them dynamic, b) discard
space for dynamic relocs.
(elf_s390_relocate_section): Initialize the GOT entries and skip
R_390_{8,16,32}/R_390_PC{16,16DBL,32DBL,32} for weak undefined
symbols with non-default visibility.
* elf64-s390.c: Likewise.
* elfxx-ia64.c (_bfd_elf_link_hash_hide_symbol): Also clear the
want_plt field.
(elfNN_ia64_relocate_section): Don't do dynamic symbol lookup
for symbols with non-default visibility.
* elflink.h (elf_link_check_versioned_symbol): Also handle the
case that a DSO references a hidden symbol which may be
satisfied by a versioned symbol in another DSO.
(elf_link_output_extsym): Check versioned definition for hidden
symbol referenced by a DSO.
non-default visibility, a) don't make them dynamic, b) discard
space for dynamic relocs.
* elf64-x86-64.c (allocate_dynrelocs): Likewise.
* elf32-ppc.c (allocate_dynrelocs): For undef weak syms with
non-default visibility, a) don't allocate plt entries, b) don't
allocate .got relocs, c) discard dyn rel space,
(ppc_elf_relocate_section): d) don't generate .got relocs, e)
don't generate dynamic relocs.
* elf64-ppc.c (allocate_dynrelocs): As above.
(ppc64_elf_relocate_section): As above.
relocation entries for weak undefined symbols with non-default
visibility.
(elf64_x86_64_relocate_section): Initialize the GOT entries and
skip R_386_32/R_386_PC32 for weak undefined symbols with
non-default visibility.
* elflink.h (elf_merge_symbol): Don't record a hidden/internal
symbol dynamic. Check indirection when removing the old
definition for symbols with non-default visibility.
(elf_add_default_symbol): Skip when told by elf_merge_symbol.
ELF_LINK_NON_GOT_REF for weakdefs when symbol already adjusted.
(ELIMINATE_COPY_RELOCS): Define as one. Use throughout.
(elf_x86_64_adjust_dynamic_symbol): For weak symbols, copy
ELF_LINK_NON_GOT_REF from weakdef.
weakdef sym has already been adjusted before treating it specially.
* elf32-i386.c (elf_i386_copy_indirect_symbol): Don't copy
ELF_LINK_NON_GOT_REF for weakdefs when symbol already adjusted.
* elf64-ppc.c (ppc64_elf_copy_indirect_symbol): Likewise.
(ppc64_elf_check_relocs): Set ELF_LINK_NON_GOT_REF.

* elflink.h (elf_merge_symbol): Call elf_backend_copy_indirect_symbol
to copy any information related to dynamic linking when we flip
the indirection.

* ld-elfvers/vers.exp (picflag): Set PIC flag for compiler.
(build_vers_lib): Support PIC.
(build_vers_lib_no_pic): New. Change all calls to build_vers_lib
to build_vers_lib_no_pic.
(build_vers_lib_pic): New.
Add tests vers26a, vers26b1, vers26b2 and vers26b3 for versioned
definition vs. normal definition in different files.
* ld-elfvers/vers26a.c: New file.
* ld-elfvers/vers26a.dsym: Likewise.
* ld-elfvers/vers26a.map: Likewise.
* ld-elfvers/vers26a.ver: Likewise.
* ld-elfvers/vers26b.c: Likewise.
* ld-elfvers/vers26b.dsym: New empty file.
* ld-elfvers/vers26b.ver: Likewise.
2003-04-27 H.J. Lu <hjl@gnu.org>
* elf-bfd.h (ELF_LINK_DYNAMIC_DEF): New.
(ELF_LINK_DYNAMIC_WEAK): New.
* elflink.h (elf_merge_symbol): Add one argument to indicate if
a symbol should be skipped. Ignore definitions in dynamic
objects for symbols with non-default visibility.
(elf_add_default_symbol): Adjusted.
(elf_link_add_object_symbols): Check if a symbol should be
skipped. Don't merge the visibility field with the one from
a dynamic object.
(elf_link_check_versioned_symbol): Use undef_bfd.
(elf_link_output_extsym): Warn if a forced local symbol is
referenced from dynamic objects. Make non-weak undefined symbol
with non-default visibility a fatal error.
