The problem has been introduced by this (huge) changeset:
2008-08-07 Richard Sandiford <rdsandif...@googlemail.com>
* elf-bfd.h (elf_backend_data): Add a "rela_plts_and_copies_p" field.
* elfxx-target.h (elf_backend_rela_plts_and_copies_p): New macro.
(elfNN_bed): Use it.
* elf.c (_bfd_elf_get_synthetic_symtab): Use rela_plts_and_copies_p
instead of default_use_rela_p to choose between ".rel.plt" and
".rela.plt".
* elflink.c (_bfd_elf_create_dynamic_sections): Use
rela_plts_and_copies_p instead of default_use_rela_p to choose
between ".rel.plt" and ".rela.plt", and between ".rel.bss" and
".rela.bss".
2008-08-07 Richard Sandiford <rdsandif...@googlemail.com>
* elf-bfd.h (MIPS_ELF_TDATA): New elf_object_id.
* elf32-mips.c (bfd_elf32_mkobject): Define.
* elf64-mips.c (bfd_elf64_mkobject): Likewise.

2008-08-07 Richard Sandiford <rdsandif...@googlemail.com>
* elfxx-mips.c (mips_elf_record_relocs): Defer allocation of a
global GOT entry when deferring allocation of dynamic relocations.
(allocate_dynrelocs): When allocating deferred dynamic relocations,
also do the deferred allocation of a GOT entry.
2008-08-07 Richard Sandiford <rdsandif...@googlemail.com>
* elfxx-mips.c (mips_got_info): Add a "reloc_only_gotno" field.
(mips_elf_got_section): Delete.
(mips_elf_sort_hash_table): Use g->reloc_only_gotno to decide
how many reloc-only entries there are.
(mips_elf_count_got_symbols): Adjust g->reloc_only_gotno as
well as g->global_gotno.
(mips_elf_make_got_per_bfd): Initialize reloc_only_gotno.
(mips_elf_multi_got): Likewise. Use gg->reloc_only_gotno
rather than gg->assigned_gotno to store the number of
reloc-only GOT entries.
(mips_elf_create_got_section): Remove the MAYBE_EXCLUDE parameter.
Initialize reloc_only_gotno.
(mips_elf_calculate_relocation): Check htab->got_info instead of
dynobj when deciding whether to call mips_elf_adjust_gp,
(_bfd_mips_elf_create_dynamic_sections): Adjust the call
to mips_elf_create_got_section.
(mips_elf_record_relocs): Likewise. Remove redundant
"dynobj == NULL" code. Do not use mips_elf_create_got_section
or mips_elf_record_global_got_symbol for R_MIPS_32, R_MIPS_REL32
and R_MIPS_64; limit global_got_area to GGA_RELOC_ONLY instead.
(_bfd_mips_elf_finish_dynamic_symbol): Use htab->sgot instead
of mips_elf_got_section.
(_bfd_mips_vxworks_finish_dynamic_symbol): Likewise.
(_bfd_mips_elf_finish_dynamic_sections): Likewise.
Move the initial assignment of G to the block that uses it;
it is used for an unrelated purpose later.
2008-08-07 Richard Sandiford <rdsandif...@googlemail.com>
* elfxx-mips.c (count_section_dynsyms): Move before the new first use.
(mips_elf_sort_hash_table): Take the output bfd as a parameter.
Remove the MAX_LOCAL parameter. Exit early if there are no
dynamic symbols, if there is no dynobj, or if there is no
GOT section. Use count_section_dynsyms instead of MAX_LOCAL.
Assert == rather than <= when checking hsd.max_unref_got_dynindx.
Also assert that g->global_gotno is right.
(mips_elf_count_forced_local_got_symbols): Rename to...
(mips_elf_count_got_symbols): ...and count global GOT entries too.
Set the global_got_area of a forced-local GGA_RELOC_ONLY symbol
to GGA_NONE.
(mips_elf_multi_got): Don't sort the symbol table.
(mips_elf_lay_out_got): Likewise. Use mips_elf_count_got_symbols
to count the number of global GOT entries.
(_bfd_mips_elf_final_link): Unconditionally call
mips_elf_sort_hash_table.
2008-08-07 Richard Sandiford <rdsandif...@googlemail.com>
* elfxx-mips.c (GGA_NORMAL, GGA_RELOC_ONLY, GGA_NONE): New macros.
(mips_elf_link_hash_entry): Add a "global_got_area" field.
(mips_elf_link_hash_newfunc): Initialize it.
(mips_elf_sort_hash_table_f): Use h->global_got_area instead of
h->root.got.offset. Do not handle forced_local symbols specially.
(mips_elf_record_global_got_symbol): Set h->global_got_area
instead of h->root.got.offset.
(mips_elf_recreate_got): Assert that h->global_got_area == GGA_NONE
for indirect and warning symbols.
(mips_elf_count_forced_local_got_symbols): Change the argument
from a "elf_link_hash_entry" to "mips_elf_link_hash_entry".
Use and set h->global_got_area instead of h->root.got.offset.
Set it to GGA_NONE for all forced-local symbols.
(mips_elf_set_global_got_offset): Set h->global_got_area
instead of h->root.got.offset. Use g->global_got_area instead
of a combination of dynindx, forced_local and tls_type.
(mips_elf_multi_got): Remove disabled code. Pass GGA_* values to
mips_elf_set_global_got_offset.
(mips_elf_lay_out_got): Use mips_elf_link_hash_traverse instead
of elf_link_hash_traverse.
(_bfd_mips_elf_copy_indirect_symbol): Copy the indirect symbol's
global_got_area to the direct symbol if the latter's value is higher.
Set the indirect symbol's area to GGA_NONE.
2008-08-07 Richard Sandiford <rdsandif...@googlemail.com>
* elf32-mips.c (elf_backend_hide_symbol): Delete.
* elfn32-mips.c (elf_backend_hide_symbol): Likewise.
* elf64-mips.c (elf_backend_hide_symbol): Likewise.
* elfxx-mips.h (elf_backend_hide_symbol): Likewise.
* elfxx-mips.c (mips_elf_link_hash_entry): Remove "forced_local"
and add "needs_lazy_stub".
(mips_elf_link_hash_newfunc): Update accordingly.
(mips_elf_link_hash_table): Remove "computed_got_sizes" and
add "lazy_stub_count".
(_bfd_mips_elf_link_hash_table_create): Update accordingly.
(mips_elf_output_extsym): Use hd->needs_lazy_stub to detect
cases where a lazy stub is being used.
(mips_elf_sort_hash_table_f): Use h->root.forced_local instead
of h->forced_local.
(mips_elf_record_global_got_symbol): Use _bfd_elf_link_hash_hide_symbol
instead of _bfd_mips_elf_hide_symbol. Do not increment local_gotno
here.
(mips_elf_allocate_dynamic_relocations): Move before new first use.
(mips_elf_check_recreate_got, mips_elf_recreate_got): New functions.
(mips_elf_resolve_final_got_entries): Move earlier in file. Make at
most two passes over the hash table. Use mips_elf_check_recreate_got
to see if there are any indirect or warning entries and
mips_elf_recreate_got to create a new GOT without them.
Return a boolean success value.
(mips_elf_count_forced_local_got_entries): New function.
(mips_elf_make_got_per_bfd): Check h->root.forced_local instead of
h->forced_local.
(mips_elf_set_global_got_offset): Likewise.
(mips_elf_set_no_stub): Replace with...
(mips_elf_forbid_lazy_stubs): ...this new function.
(mips_elf_resolve_final_got_entry): Delete.
(mips_elf_multi_got): Fix formatting. Use mips_elf_forbid_lazy_stubs
instead of mips_elf_set_no_stub. Move the code that sets
global offsets and allocates dynamic relocations from the main
_bfd_mips_elf_size_dynamic_sections loop to here.
(_bfd_mips_elf_adjust_dynamic_symbol): Do not allocate room in
.MIPS.stubs here; just set hmips->needs_lazy_stub and increment
htab->lazy_stub_count.
(_bfd_mips_elf_always_size_sections): Move the stub-estimation
code to mips_elf_estimate_stub_size and the GOT-sizing code to
mips_elf_lay_out_got. Do not call these functions here.
(mips_elf_estimate_stub_size): New function, split
out from _bfd_mips_elf_always_size_sections. Call
mips_elf_resolve_final_got_entries earlier. Count the number
of forced-local entries. Do not add stub sizes to loadable_size;
after this patch, the stub sizes are already included in the main
estimate. Allocate dynamic relocations here rather than in the
main _bfd_mips_elf_size_dynamic_sections loop.
(mips_elf_estimate_stub_size): New function, split out from
_bfd_mips_elf_always_size_sections.
(mips_elf_allocate_lazy_stub): New function.
(mips_elf_lay_out_lazy_stubs): Likewise.
(_bfd_mips_elf_size_dynamic_sections): Call
mips_elf_estimate_stub_size,
mips_elf_lay_out_got and mips_elf_lay_out_lazy_stubs. Do not handle
the allocation of sreldyn specially.
(_bfd_mips_elf_hide_symbol): Delete.
2008-08-07 Richard Sandiford <rdsandif...@googlemail.com>
* elfxx-mips.c (allocate_dynrelocs): Ignore indirect and warning
symbols.
