+Subject: [PATCH] Fix E500 with SPE errors with the _Decimal64 type
+
+[gcc]
+2014-04-21 Michael Meissner  <meissner@linux.vnet.ibm.com>
+
+	PR target/60735
+	* config/rs6000/rs6000.md (mov<mode>_softfloat32, FMOVE64 case):
+	If mode is DDmode and TARGET_E500_DOUBLE allow move.
+
+	* config/rs6000/rs6000.c (rs6000_debug_reg_global): Print some
+	more debug information for E500 if -mdebug=reg.
+
+[gcc/testsuite]
+2014-04-21  Michael Meissner  <meissner@linux.vnet.ibm.com>
+
+	PR target/60735
+	* gcc.target/powerpc/pr60735.c: New test.  Insure _Decimal64 does
+	not cause errors if -mspe.
+
+Upstream status: Accepted
+
+This solves upstream bug 60735 
+(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60735).
