From c353e543fe20cb01262548486ee2c9af70608a01 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Wed, 15 Jan 2014 03:59:42 -0800 Subject: Revert the last change It has been fixed by commit 4199e3b8669d0a36448687850374fdc2ad7240b6 Author: Alan Modra Date: Wed Jan 15 21:50:55 2014 +1030 non-PIC references to __ehdr_start in pie and shared Rather than hacking every backend to not discard dynamic relocations against an undefined hidden __ehdr_start, make it appear to be defined early. We want __ehdr_start hidden before size_dynamic_sections so that it isn't put in .dynsym, but we do need the dynamic relocations for a PIE or shared library with a non-PIC reference. Defining it early is wrong if we don't actually define the symbol later to its proper value. (In some cases we want to leave the symbol undefined, for example, when the ELF header isn't loaded, and we don't have this infomation available in before_allocation.) * elf32-i386.c (elf_i386_allocate_dynrelocs): Revert the last change. * elf64-x86-64.c (elf_x86_64_allocate_dynrelocs): Likewise. --- bfd/elf64-x86-64.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) (limited to 'bfd/elf64-x86-64.c') diff --git a/bfd/elf64-x86-64.c b/bfd/elf64-x86-64.c index f364fe4..edee8ec 100644 --- a/bfd/elf64-x86-64.c +++ b/bfd/elf64-x86-64.c @@ -2473,12 +2473,9 @@ elf_x86_64_allocate_dynrelocs (struct elf_link_hash_entry *h, void * inf) } /* Also discard relocs on undefined weak syms with non-default - visibility.
