From 09af52f78e58d9aee0980276833bf3adee3ed07b Mon Sep 17 00:00:00 2001 From: Liu Yu Date: Mon, 5 Sep 2011 17:01:23 +0800 Subject: [PATCH] powerpc/math_emu/efp: Look for errata handler when type mismatches We already have cpu a005 errata handler when instruction cannot be recognized. Before we lookup the inst, there's type checking, and we also need to handle it in errata handler when the type checking failed.
