From 8860955fbe0eaf412839ef492a67415613001ac5 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Sun, 19 Dec 2004 23:24:46 +0000 Subject: * 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.
