Subject: * elf-bfd.h (struct elf_link_hash_entry): Remove
linker_section_pointer field. (enum elf_linker_section_enum):
Delete. (struct elf_linker_section): Delete. (struct
elf_linker_section_pointers): Delete. (struct elf_obj_tdata): Remove #if 0
chunk. Remove linker_section. Make linker_section_pointers a void**.
(elf_local_ptr_offsets, elf_linker_section): Don't define. *
elf32-ppc.c (enum elf_linker_section_enum): New, cut-down version of old
item in elf-bfd.h. (struct elf_linker_section): Likewise. (struct
elf_linker_section_pointers): Likewise. (elf_local_ptr_offsets):
Define. (struct ppc_elf_link_hash_entry): Add linker_section_pointer.
(ppc_elf_link_hash_newfunc): Init it. (struct ppc_elf_link_hash_table): Add
sbss. (ppc_elf_link_hash_table_create): zmalloc rather than clearing
individual fields. (elf_create_linker_section): Fold into..
(ppc_elf_create_linker_section): ..here. Remove hole_size code. Make
rela section here if shared. (elf_find_pointer_linker_section): Pass lsect
rather than enum. (elf_create_pointer_linker_section): Adjust. zalloc
rather than clearing in a loop. (elf_finish_pointer_linker_section):
Adjust. Don't make rela section here. (ppc_elf_check_relocs):
Adjust. (ppc_elf_add_symbol_hook): Tighten hash creator test. Remove
code creating .sbss by hand. * elf.c (_bfd_elf_link_hash_newfunc):
Adjust.
