Subject: 	* elf64-ppc.c (struct ppc64_elf_obj_tdata): Add opd_relocs.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8860955fbe0eaf412839ef492a67415613001ac5;p=binutils-gdb.git

	* elf64-ppc.c (struct ppc64_elf_obj_tdata): Add opd_relocs.
	(opd_entry_value): Use opd_relocs if available.
	(ppc64_elf_relocate_section): Don't set reloc_done.  Instead
	copy .opd relocations to opd_relocs.
	(ppc64_elf_edit_toc): Set rel_hdr.sh_size after editing relocs.
