mips_elf_output_dynamic_relocation accordingly.
(mips_elf_multi_got): Use htab->reserved_gotno instead of
MIPS_RESERVED_GOTNO.
(mips_elf_create_got_section): Don't allocate reserved GOT
entries here. Unconditionally create .got.plt, but don't
set its alignment here.
(mips_elf_relocation_needs_la25_stub): New function.
(mips_elf_calculate_relocation): Redirect branches and jumps to
a non-PIC stub if one exists. Check !h->has_static_relocs instead
of !htab->is_vxworks when deciding whether to create dynamic
relocations for R_MIPS_32, R_MIPS_REL32 and R_MIPS_64.
(_bfd_mips_elf_create_dynamic_sections): Unconditionally call
_bfd_elf_create_dynamic_sections. Unconditionally set up
htab->splt and htab->sdynbss. Set htab->srelplt to ".rel.plt"
if !htab->is_vxworks. Add non-VxWorks values of
htab->plt_header_size and htab->plt_entry_size.
(_bfd_mips_elf_check_relocs): Set pointer_equality_needed for
non-branch static relocations. Set has_nonpic_branches when an la25
stub might be required. Set can_make_dynamic_p to TRUE if R_MIPS_32,
R_MIPS_REL32 and R_MIPS_64 relocations can be made dynamic,
rather than duplicating the condition. Do not make them dynamic
for read-only sections in non-PIC executable objects.
Do not protect this code with dynobj == NULL || htab->sgot == NULL;
handle each group of cases separately. Add a default case that
sets has_static_relocs for non-GOT relocations that cannot be
made dynamic. Don't set is_relocation_target and is_branch_target.
Reject non-PIC static relocations in shared objects.
(_bfd_mips_vxworks_adjust_dynamic_symbol): Fold into...
(_bfd_mips_elf_adjust_dynamic_symbol): ...here, using
htab->use_plts_and_copy_relocs instead of htab->is_vxworks
to select PLT and copy-reloc handling. Set the alignment of
.plt and .got.plt when allocating the first entry. Generalize
code to handle REL as well as RELA sections and 64-bit as well as
32-bit GOT entries. Complain if we find a static-only reloc
against an externally-defined symbol and if we cannot create
dynamic relocations for it. Allocate copy relocs using
mips_elf_allocate_dynamic_relocations on non-VxWorks targets.
Set possibly_dynamic_relocs to 0 when using PLTs or copy relocs.
Skip reserved .got.plt entries.
(_bfd_mips_elf_always_size_sections): Use mips_elf_check_symbols
instead of mips_elf_check_mips16_stubs to process each symbol.
Do the traversal for relocatable objects too.
(mips_elf_lay_out_got): Use htab->reserved_gotno instead of
MIPS_RESERVED_GOTNO.
(_bfd_mips_elf_size_dynamic_sections): Exclude sdynbss if it
is empty. Extend the DT_PLTREL, DT_JMPREL and DT_PLTRELSZ handling
to non-VxWorks targets. Only add DT_REL{,A}, DT_REL{,A}SZ and
DT_REL{,A}ENT if .rel.dyn is nonempty. Create a symbol for the
PLT. Allocate a nop at the end of the PLT. Allocate DT_MIPS_PLTGOT.
(mips_elf_create_la25_stub_info): New function.
(_bfd_mips_elf_finish_dynamic_symbol): Write out PLT entries
and copy relocs where necessary. Check pointer_equality_needed.
(mips_finish_exec_plt): New function.
(_bfd_mips_elf_finish_dynamic_sections): Always set DT_PLTGOT
to the beginning of htab->sgot. Use htab->reserved_gotno instead
of MIPS_RESERVED_GOTNO. Assert htab->use_plts_and_copy_relocs
instead of htab->is_vxworks for DT_PLTREL, DT_PLTRELSZ and DT_JMPREL.
Set DT_PLTREL to DT_REL instead of DT_RELA on non-VxWorks targets.
Use mips_finish_exec_plt to create non-VxWorks PLT headers. Set
DT_MIPS_PLTGOT.
(_bfd_mips_elf_copy_indirect_symbol): Copy has_static_relocs
from the indirect symbol to the direct symbol. Also copy
has_nonpic_branches for indirect symbols.
(_bfd_mips_elf_get_target_dtag): Handle DT_MIPS_PLTGOT and
DT_MIPS_RWPLT.
(_bfd_mips_elf_link_hash_table_create): Initialize the new
mips_elf_link_hash_table fields.
(_bfd_mips_vxworks_link_hash_table_create): Set
use_plts_and_copy_relocs to TRUE. Use TRUE rather than 1
when setting is_vxworks.
(_bfd_mips_elf_use_plts_and_copy_relocs): New function.
(_bfd_mips_elf_final_link): Call mips_elf_create_la25_stub for
each la25_stub.
(_bfd_mips_elf_merge_private_bfd_data): Treat dynamic objects
as PIC. Generalize message about linking PIC and non-PIC.
(_bfd_mips_elf_plt_sym_val, _bfd_mips_post_process_headers): New
functions.

entries here. Unconditionally create .got.plt, but don't
set its alignment here.
(mips_elf_relocation_needs_la25_stub): New function.

.plt and .got.plt when allocating the first entry. Generalize
code to handle REL as well as RELA sections and 64-bit as well as
32-bit GOT entries. Complain if we find a static-only reloc
against an externally-defined symbol and if we cannot create
dynamic relocations for it. Allocate copy relocs using
mips_elf_allocate_dynamic_relocations on non-VxWorks targets.
Set possibly_dynamic_relocs to 0 when using PLTs or copy relocs.
Skip reserved .got.plt entries.
(_bfd_mips_elf_always_size_sections): Use mips_elf_check_symbols
instead of mips_elf_check_mips16_stubs to process each symbol.
Do the traversal for relocatable objects too.
(mips_elf_lay_out_got): Use htab->reserved_gotno instead of
MIPS_RESERVED_GOTNO.
(_bfd_mips_elf_size_dynamic_sections): Exclude sdynbss if it
is empty. Extend the DT_PLTREL, DT_JMPREL and DT_PLTRELSZ handling
to non-VxWorks targets. Only add DT_REL{,A}, DT_REL{,A}SZ and
DT_REL{,A}ENT if .rel.dyn is nonempty. Create a symbol for the
PLT. Allocate a nop at the end of the PLT. Allocate DT_MIPS_PLTGOT.

to the beginning of htab->sgot. Use htab->reserved_gotno instead
of MIPS_RESERVED_GOTNO. Assert htab->use_plts_and_copy_relocs
instead of htab->is_vxworks for DT_PLTREL, DT_PLTRELSZ and DT_JMPREL.
Set DT_PLTREL to DT_REL instead of DT_RELA on non-VxWorks targets.
Use mips_finish_exec_plt to create non-VxWorks PLT headers. Set
DT_MIPS_PLTGOT.
(_bfd_mips_elf_copy_indirect_symbol): Copy has_static_relocs
from the indirect symbol to the direct symbol. Also copy
has_nonpic_branches for indirect symbols.

a non-PIC stub if one exists. Check !h->has_static_relocs instead
of !htab->is_vxworks when deciding whether to create dynamic
relocations for R_MIPS_32, R_MIPS_REL32 and R_MIPS_64.
(_bfd_mips_elf_create_dynamic_sections): Unconditionally call
_bfd_elf_create_dynamic_sections. Unconditionally set up
htab->splt and htab->sdynbss. Set htab->srelplt to ".rel.plt"

stub might be required. Set can_make_dynamic_p to TRUE if R_MIPS_32,
R_MIPS_REL32 and R_MIPS_64 relocations can be made dynamic,
rather than duplicating the condition. Do not make them dynamic
for read-only sections in non-PIC executable objects.
Do not protect this code with dynobj == NULL || htab->sgot == NULL;
handle each group of cases separately. Add a default case that
sets has_static_relocs for non-GOT relocations that cannot be
made dynamic. Don't set is_relocation_target and is_branch_target.

.plt and .got.plt when allocating the first entry. Generalize
code to handle REL as well as RELA sections and 64-bit as well as
32-bit GOT entries. Complain if we find a static-only reloc
against an externally-defined symbol and if we cannot create
dynamic relocations for it. Allocate copy relocs using
mips_elf_allocate_dynamic_relocations on non-VxWorks targets.
Set possibly_dynamic_relocs to 0 when using PLTs or copy relocs.
Skip reserved .got.plt entries.
(_bfd_mips_elf_always_size_sections): Use mips_elf_check_symbols
instead of mips_elf_check_mips16_stubs to process each symbol.
Do the traversal for relocatable objects too.
(mips_elf_lay_out_got): Use htab->reserved_gotno instead of
MIPS_RESERVED_GOTNO.
(_bfd_mips_elf_size_dynamic_sections): Exclude sdynbss if it
is empty. Extend the DT_PLTREL, DT_JMPREL and DT_PLTRELSZ handling
to non-VxWorks targets. Only add DT_REL{,A}, DT_REL{,A}SZ and
DT_REL{,A}ENT if .rel.dyn is nonempty. Create a symbol for the
PLT. Allocate a nop at the end of the PLT. Allocate DT_MIPS_PLTGOT.
(mips_elf_create_la25_stub_info): New function.
(_bfd_mips_elf_finish_dynamic_symbol): Write out PLT entries
and copy relocs where necessary. Check pointer_equality_needed.
(mips_finish_exec_plt): New function.
(_bfd_mips_elf_finish_dynamic_sections): Always set DT_PLTGOT
to the beginning of htab->sgot. Use htab->reserved_gotno instead
of MIPS_RESERVED_GOTNO. Assert htab->use_plts_and_copy_relocs
instead of htab->is_vxworks for DT_PLTREL, DT_PLTRELSZ and DT_JMPREL.
Set DT_PLTREL to DT_REL instead of DT_RELA on non-VxWorks targets.
Use mips_finish_exec_plt to create non-VxWorks PLT headers. Set
DT_MIPS_PLTGOT.
(_bfd_mips_elf_copy_indirect_symbol): Copy has_static_relocs
from the indirect symbol to the direct symbol. Also copy
has_nonpic_branches for indirect symbols.
(_bfd_mips_elf_get_target_dtag): Handle DT_MIPS_PLTGOT and
DT_MIPS_RWPLT.

use_plts_and_copy_relocs to TRUE. Use TRUE rather than 1
when setting is_vxworks.
(_bfd_mips_elf_use_plts_and_copy_relocs): New function.
(_bfd_mips_elf_final_link): Call mips_elf_create_la25_stub for
each la25_stub.

against an externally-defined symbol and if we cannot create
dynamic relocations for it. Allocate copy relocs using
mips_elf_allocate_dynamic_relocations on non-VxWorks targets.
Set possibly_dynamic_relocs to 0 when using PLTs or copy relocs.
Skip reserved .got.plt entries.
(_bfd_mips_elf_always_size_sections): Use mips_elf_check_symbols
instead of mips_elf_check_mips16_stubs to process each symbol.
Do the traversal for relocatable objects too.
(mips_elf_lay_out_got): Use htab->reserved_gotno instead of
MIPS_RESERVED_GOTNO.
(_bfd_mips_elf_size_dynamic_sections): Exclude sdynbss if it
is empty. Extend the DT_PLTREL, DT_JMPREL and DT_PLTRELSZ handling
to non-VxWorks targets. Only add DT_REL{,A}, DT_REL{,A}SZ and
DT_REL{,A}ENT if .rel.dyn is nonempty. Create a symbol for the
PLT. Allocate a nop at the end of the PLT. Allocate DT_MIPS_PLTGOT.
(mips_elf_create_la25_stub_info): New function.
(_bfd_mips_elf_finish_dynamic_symbol): Write out PLT entries
and copy relocs where necessary. Check pointer_equality_needed.
(mips_finish_exec_plt): New function.

to the beginning of htab->sgot. Use htab->reserved_gotno instead
of MIPS_RESERVED_GOTNO. Assert htab->use_plts_and_copy_relocs
instead of htab->is_vxworks for DT_PLTREL, DT_PLTRELSZ and DT_JMPREL.
Set DT_PLTREL to DT_REL instead of DT_RELA on non-VxWorks targets.
Use mips_finish_exec_plt to create non-VxWorks PLT headers. Set
DT_MIPS_PLTGOT.
(_bfd_mips_elf_copy_indirect_symbol): Copy has_static_relocs
from the indirect symbol to the direct symbol. Also copy
has_nonpic_branches for indirect symbols.
(_bfd_mips_elf_get_target_dtag): Handle DT_MIPS_PLTGOT and
DT_MIPS_RWPLT.
(_bfd_mips_elf_link_hash_table_create): Initialize the new
mips_elf_link_hash_table fields.

MIPS_RESERVED_GOTNO.
(mips_elf_create_got_section): Don't allocate reserved GOT
entries here. Unconditionally create .got.plt, but don't
set its alignment here.
(mips_elf_relocation_needs_la25_stub): New function.
(mips_elf_calculate_relocation): Redirect branches and jumps to
a non-PIC stub if one exists. Check !h->has_static_relocs instead
of !htab->is_vxworks when deciding whether to create dynamic
relocations for R_MIPS_32, R_MIPS_REL32 and R_MIPS_64.
(_bfd_mips_elf_create_dynamic_sections): Unconditionally call
_bfd_elf_create_dynamic_sections. Unconditionally set up
htab->splt and htab->sdynbss. Set htab->srelplt to ".rel.plt"
if !htab->is_vxworks. Add non-VxWorks values of
htab->plt_header_size and htab->plt_entry_size.
(_bfd_mips_elf_check_relocs): Set pointer_equality_needed for
non-branch static relocations. Set has_nonpic_branches when an la25
stub might be required. Set can_make_dynamic_p to TRUE if R_MIPS_32,
R_MIPS_REL32 and R_MIPS_64 relocations can be made dynamic,
rather than duplicating the condition. Do not make them dynamic
for read-only sections in non-PIC executable objects.
Do not protect this code with dynobj == NULL || htab->sgot == NULL;
handle each group of cases separately. Add a default case that
sets has_static_relocs for non-GOT relocations that cannot be
made dynamic. Don't set is_relocation_target and is_branch_target.

htab->use_plts_and_copy_relocs instead of htab->is_vxworks
to select PLT and copy-reloc handling. Set the alignment of
.plt and .got.plt when allocating the first entry. Generalize
code to handle REL as well as RELA sections and 64-bit as well as
32-bit GOT entries. Complain if we find a static-only reloc
against an externally-defined symbol and if we cannot create
dynamic relocations for it. Allocate copy relocs using
mips_elf_allocate_dynamic_relocations on non-VxWorks targets.
Set possibly_dynamic_relocs to 0 when using PLTs or copy relocs.
Skip reserved .got.plt entries.
(_bfd_mips_elf_always_size_sections): Use mips_elf_check_symbols
instead of mips_elf_check_mips16_stubs to process each symbol.
Do the traversal for relocatable objects too.
(mips_elf_lay_out_got): Use htab->reserved_gotno instead of
MIPS_RESERVED_GOTNO.
(_bfd_mips_elf_size_dynamic_sections): Exclude sdynbss if it
is empty. Extend the DT_PLTREL, DT_JMPREL and DT_PLTRELSZ handling
to non-VxWorks targets. Only add DT_REL{,A}, DT_REL{,A}SZ and
DT_REL{,A}ENT if .rel.dyn is nonempty. Create a symbol for the
PLT. Allocate a nop at the end of the PLT. Allocate DT_MIPS_PLTGOT.
(mips_elf_create_la25_stub_info): New function.
(_bfd_mips_elf_finish_dynamic_symbol): Write out PLT entries
and copy relocs where necessary. Check pointer_equality_needed.
(mips_finish_exec_plt): New function.
(_bfd_mips_elf_finish_dynamic_sections): Always set DT_PLTGOT
to the beginning of htab->sgot. Use htab->reserved_gotno instead
of MIPS_RESERVED_GOTNO. Assert htab->use_plts_and_copy_relocs
instead of htab->is_vxworks for DT_PLTREL, DT_PLTRELSZ and DT_JMPREL.
Set DT_PLTREL to DT_REL instead of DT_RELA on non-VxWorks targets.
Use mips_finish_exec_plt to create non-VxWorks PLT headers. Set
DT_MIPS_PLTGOT.
(_bfd_mips_elf_copy_indirect_symbol): Copy has_static_relocs
from the indirect symbol to the direct symbol. Also copy
has_nonpic_branches for indirect symbols.
(_bfd_mips_elf_get_target_dtag): Handle DT_MIPS_PLTGOT and
DT_MIPS_RWPLT.
(_bfd_mips_elf_link_hash_table_create): Initialize the new
mips_elf_link_hash_table fields.
(_bfd_mips_vxworks_link_hash_table_create): Set
use_plts_and_copy_relocs to TRUE. Use TRUE rather than 1
when setting is_vxworks.
(_bfd_mips_elf_use_plts_and_copy_relocs): New function.
(_bfd_mips_elf_final_link): Call mips_elf_create_la25_stub for
each la25_stub.
