Replace caching of external symbols with caching of internal symbols obtained
from calling bfd_elf_get_elf_syms().
Fixup problems with freeing cached allocated memory blocks.
(bfd_pj_arch): Use bfd_default_scan.
* cpu-v850.c (scan): Remove.
(N): Use bfd_default_scan.
* cpu-z8k.c (scan_mach): Remove.
(arch_info_struct, bfd_z8k_arch): Reorganize so that the default is
first. Use bfd_default_scan.
(create_got_section, allocate_dynrelocs, readonly_dynrelocs):
Likewise.
(struct elf_sh_pcrel_relocs_copied): Removed.
(struct elf_sh_dyn_relocs): New.
(struct elf_sh_link_hash_entry): Replace pcrel_relocs_copied
field with dyn_relocs.
(struct elf_sh_link_hash_table): Add short-cuts to get dynamic
sections and sym_sec.
(sh_elf_link_hash_newfunc): Clear dyn_relocs.
(sh_elf_link_hash_table_create): Clear shorts-cuts and sym_sec.
(sh_elf_create_dynamic_sections): Use create_got_section instead
of _bfd_elf_create_got_section.
(sh_elf_check_relocs): Likewise.
(sh_elf_create_dynamic_sections): Use short-cuts to the dynamic
sections.
(sh_elf_adjust_dynamic_symbol, sh_elf_size_dynamic_sections,
sh_elf_relocate_section, sh_elf_check_relocs,
sh_elf_finish_dynamic_symbol, sh_elf_finish_dynamic_sections):
Likewise.
(sh_elf_adjust_dynamic_symbol): Handle nocopyreloc. Keep the
dynamic relocations and avoiding the copy relocation when we
didn't find any dynamic relocations in the section which has
contents or is read-only.
(WILL_CALL_FINISH_DYNAMIC_SYMBOL): New.
(sh_elf_size_dynamic_sections): Don't reset the size of
.rela.got section even if dynamic_sections_created flag is off.
Don't use sh_elf_discard_copies. Scan all input bfd and use
allocate_dynrelocs. Call readonly_dynrelocs to determine
whether we need DT_TEXTREL.
(sh_elf_adjust_dynamic_symbol): Use plt.refcount to determine
whether the symbol was never referred to.
(sh_elf_relocate_section): Use WILL_CALL_FINISH_DYNAMIC_SYMBOL.
(sh_elf_gc_sweep_hook): Fill with the real sweep function.
(sh_elf_check_relocs): Call create_got_section if the short-cut
to .got is null. Increment reference counters only instead of
allocating space on dynamic sections here. Don't conditionalize
uninitialized got.offset value when marking the symbol as a
global offset table entry. Keep relocations for symbols satisfied
by a dynamic library to avoid copy relocations for the symbol.
Set dynobj field of an elf hash table if needed.
(sh_elf_finish_dynamic_sections): Handle null section pointer
correctly.
(elf_backend_copy_indirect_symbol): Defined.
(elf_backend_can_refcount): Defined.
contents of .got.plt[2] to tr0, not address of .got.plt.
(sh_elf_finish_dynamic_symbol): Do not apply GOT_BIAS when
patching absolute plt entry. For shmedia plt entry, set bottom bit
of branch to plt0 as this is a branch to an shmedia instruction.
* elf64-sh64.c (elf_sh64_plt0_entry_be, elf_sh64_plt0_entry_le):
Copy contents of .got.plt[2] to tr0, not address of .got.plt.
(elf_sh64_plt_entry_be, elf_sh64_plt_entry_le): Use ptrel to
branch to plt0.
(sh64_elf64_finish_dynamic_symbol): Do not apply GOT_BIAS when
patching absolute plt entry. For shmedia plt entry, branch to
plt0 is now ptrel, so use relative offset. Set bottom bit of
branch target as it is a branch to an shmedia instruction.
instructions.
(m68hc11_direct_relax): New to define table of relaxable instructions.
(find_relaxable_insn): New, find a relaxable insn.
(compare_reloc): New to compare two relocs.
(m68hc11_elf_relax_section): New, relax text sections.
(m68hc11_elf_relax_delete_bytes): New, delete bytes and adjust branchs.
(elf32_m68hc11_check_relocs): New function for GC support.
(elf32_m68hc11_relocate_section): New function for GC support.
(bfd_elf32_bfd_relax_section): Define to support linker relaxation.
(elf_backend_check_relocs): Likewise.
(elf_backend_relocate_section): Likewise.
(_bfd_m68hc11_elf_merge_private_bfd_data): New function.
(_bfd_m68hc11_elf_set_private_flags): New function.
Use them to set/check/print ELF flags specific to 68HC11.
* elf32-m68hc12.c (_bfd_m68hc12_elf_print_private_bfd_data): New.
(_bfd_m68hc12_elf_merge_private_bfd_data): New function.
(_bfd_m68hc12_elf_set_private_flags): New function.
Use them to set/check/print ELF flags specific to 68HC12.
fix masks for PC-rel relocs.
(m68hc11_elf_ignore_reloc): New function.
* elf32-m68hc12.c (m68hc12_elf_special_reloc): New to handle specific
68HC12 banked addressing relocs.
(m68hc12_phys_addr): New to compute physical address of banked memory.
(m68hc12_phys_page): Likewise for page.
(m68hc12_addr_is_banked): New to see if address is in banked area.
(elf_m68hc12_howto_table): Add new relocs and rename to xx12.
