From f574a76a3b19848ac61814756716e26f85f2c3f7 Mon Sep 17 00:00:00 2001 From: Robin Getz Date: Thu, 9 Jul 2009 15:11:52 +0000 Subject: Blackfin: work around anomaly 05000189 Similar to anomaly 05000281 but not as bad, we cannot return to the instruction causing a fault otherwise we'll trigger a second false exception. The system can still recover, but it isn't correct.
