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.
