From d0b5d9da5de280120b73e776663f6a3024f225f4 Mon Sep 17 00:00:00 2001 From: Albert ARIBAUD Date: Sat, 22 Feb 2014 17:53:42 +0100 Subject: arm: make _end compiler-generated This prevents references to _end from generating absolute relocation records. This change is binary invariant for ARM targets.
