+==================== work095, patch #9.
+
+Do not enable -mblock-ops-vector-pair.
+
+Testing has shown that using the load vector pair and store vector pair
+instructions for block moves has some performance issues on power10.
+
+A patch on June 11th modified the code so that GCC would not set
+-mblock-ops-vector-pair by default if we are tuning for power10, but it
+would set the option if we were tuning for a different machine and have
+load and store vector pair instructions enabled.
+
+This patch just eliminates the code setting -mblock-ops-vector-pair at
+all.

-==================== work095, patch #3.
-
-Make -mblock-ops-vector-pair option valid as an ISA option.
-
-I needed to turn off using load vector pair and store vector pair
-instructions on the power10 for performance reasons.  It is likely that in
-future machines, we will want to enable these instructions for block moves
-and copies.  This patch adds the -mblock-ops-vector-pair option mask to
-POWERPC_MASKS so that it is automatically set and cleared as we change the
-target cpu.
