From 47bd65ef057fb71b02b32741d5cfcaf03e2f0918 Mon Sep 17 00:00:00 2001 From: Albert ARIBAUD Date: Tue, 11 Jun 2013 14:17:34 +0200 Subject: [PATCH] arm: make __rel_dyn_{start, end} compiler-generated MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This change is only done where needed: some linker scripts may contain relocation symbols yet remain unchanged. __rel_dyn_start and __rel_dyn_end each requires its own output section; putting them in relocation sections changes their flags and breaks relocation.
