* bfd-in.h (_bfd_elf_fix_excluded_sec_syms): Declare. (_bfd_elf_provide_section_bound_symbols): Remove param name. Formatting. * bfd-in2.h: Regenerate. * elflink.c (bfd_elf_gc_sections): Don't call generic function. (_bfd_elf_provide_symbol): Formatting. (_bfd_elf_provide_section_bound_symbols): Remove all hacks, just create section relative syms. (fix_syms, _bfd_elf_fix_excluded_sec_syms): New functions. * elf32-ppc.c (ppc_elf_set_sdata_syms): Use _bfd_elf_provide_section_bound_symbols. * reloc.c (bfd_mark_used_section): Delete. (bfd_generic_gc_sections): Don't call the above. ld/ * ldlang.c (strip_excluded_output_sections): Don't call bfd_gc_sections. * emultempl/elf32.em (gld*_provide_bound_symbols): Move. (gld*_provide_init_fini_syms): Move. (gld*_before_allocation): Call the above from here.. (gld*_finish): ..not here.
