* elf32-ppc.c (struct elf_linker_section): Remove sym_hash and
sym_offset. Add name, bss_name, sym_name, sym_val.
(struct ppc_elf_link_hash_table): Remove sdata and sdata2 pointers.
Add sdata array of elf_linker_section_t.
(ppc_elf_link_hash_table_create): Set name, sym_name, and bss_name.
(enum elf_linker_section_enum): Delete.
(ppc_elf_create_linker_section): Rewrite. Don't create syms here.
(ppc_elf_check_relocs): Delay ppc_elf_create_linker_section until
the special sections are needed. Adjust htab->sdata refs.
Ensure dynobj is set in sreloc code.
(ppc_elf_size_dynamic_sections): Strip sdata sections.
(ppc_elf_set_sdata_syms): New function.
(elf_finish_pointer_linker_section): Use 0x8000 for sym_offset.
(ppc_elf_relocate_section): Adjust references to htab->sdata. Use
sym_val instead of sym_hash.
* elf32-ppc.h (ppc_elf_set_sdata_syms): Declare.
ld/
* emultempl/ppc32elf.em (gld${EMULATION_NAME}_after_allocation): New
function.
(LDEMUL_AFTER_ALLOCATION): Define.
