From ffffcd15948d9d1081afd6f1215a9850bd9f4bd5 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Wed, 3 Aug 2016 20:45:22 +0300 Subject: [PATCH] arc: Add debug messages during relocation fixups This might be useful to make sure relocation fixups really happen. And since this info gets printed only in DEBUG build it doesn't really hurt normal execution.
