From 873b5271f878a11729fb4602c6ce967d0ff81119 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 14 Dec 2009 13:55:20 -0800 Subject: x86: Regex support and known-movable symbols for relocs, fix _end This adds a new category of symbols to the relocs program: symbols which are known to be relative, even though the linker emits them as absolute; this is the case for symbols that live in the linker script, which currently applies to _end. Unfortunately the previous workaround of putting _end in its own empty section was defeated by newer binutils, which remove empty sections completely. This patch also changes the symbol matching to use regular expressions instead of hardcoded C for specific patterns. This is a decidedly non-minimal patch: a modified version of the relocs program is used as part of the Syslinux build, and this is basically a backport to Linux of some of those changes; they have thus been well tested.
