From: Alan Modra Date: Thu, 12 Dec 2002 10:17:14 +0000 (+0000) Subject: * elf32-i386.c (elf_i386_finish_dynamic_sections): Add output_offset X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=9bf1ef982e078863bd4a6e5285c9a810f1317c71;p=pf3gnuchains%2Fpf3gnuchains3x.git * elf32-i386.c (elf_i386_finish_dynamic_sections): Add output_offset to DT_JMPREL. Use srelplt input section size for DT_PLTRELSZ and DT_RELSZ adjustment, not output section. Avoid writing tags when unchanged. Don't assume linker script is sane, adjust DT_REL too. * elf32-hppa.c (elf32_hppa_finish_dynamic_sections): Just use raw size of srelplt for DT_PLTRELSZ. Use srelplt input section size for DT_RELASZ adjustment, not output section. Avoid writing tags when unchanged. Adjust DT_RELA. * elf64-ppc.c (ppc64_elf_finish_dynamic_sections): Tweaks for better formatting. Avoid writing tags when unchanged. Adjust DT_RELA. --- diff --git a/bfd/ChangeLog b/bfd/ChangeLog index c78a2d79b0..89da4f21d9 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,16 @@ +2002-12-12 Alan Modra + + * elf32-i386.c (elf_i386_finish_dynamic_sections): Add output_offset + to DT_JMPREL.
