[Qemu-devel] [PATCH 3/3] target-ppc : Add PPC_FLOAT_64 type to fctid, fc


From: Pierre Mallard
Subject: [Qemu-devel] [PATCH 3/3] target-ppc : Add PPC_FLOAT_64 type to fctid, fctidz and fcfid and remove their TARGET_PPC64 restriction
Date: Wed, 10 Sep 2014 07:03:33 +0200

Apply the new PPC_FLOAT_64 flag to fctid[z] and fcfid. 
May also be applyed to fctidu[z] and fcfid[su][z], but since they are not 
mentionned in xilinx documentation it might not be needed yet.
