* elf64-ppc.c (ppc64_elf_get_synthetic_symtab): Do not check for
SEC_LOAD.
gdb/
Fix convert_code_addr_to_desc_addr for ppc64 files after eu-strip.
* elfread.c (elf_symfile_read): New variable synth_abfd, pass it to
bfd_get_synthetic_symtab.
* jit.c (jit_register_code): Pass NULL to the new parameter parent.
* machoread.c (macho_add_oso_symfile): Pass main_objfile to the new
parameter parent, remove the call to add_separate_debug_objfile.

* symfile-mem.c (symbol_file_add_from_memory): Likewise.
* symfile.c (symbol_file_add_with_addrs_or_offsets): New parameter
parent, new comment for it, call add_separate_debug_objfile for it.
(symbol_file_add_separate): Pass objfile as the parameter parent,
remove the call to add_separate_debug_objfile.
(symbol_file_add_from_bfd): New parameter parent, pass it.
(symbol_file_add): Pass NULL to the new parameter parent.
* symfile.h (symbol_file_add_from_bfd): New parameter parent.
