+# DP: Proposed patch for PR target/67211
+
+2015-08-19  Michael Meissner  <meissner@linux.vnet.ibm.com>
+
+	PR target/67211
+	* config/rs6000/rs6000-cpus.def (ISA_2_7_MASKS_SERVER): Set
+	-mefficient-unaligned-vsx on ISA 2.7.
+
+	* config/rs6000/rs6000.opt (-mefficient-unaligned-vsx): Convert
+	option to a masked option.
+
+	* config/rs6000/rs6000.c (rs6000_option_override_internal): Rework
+	logic for -mefficient-unaligned-vsx so that it is set via an arch
+	ISA option, instead of being set if -mtune=power8 is set.
