+==================== 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.

-Make BLOCK_OPTS options settable with ISA flags.
-
-In wanting to turn off block moves from generating load and store vector
-pair operations on the power10, I noticed that the options for controlling
-the code block moves generate (OPTION_MASK_BLOCK_OPS_UNALIGNED_VSX and
-OPTION_MASK_BLOCK_OPS_VECTOR_PAIR) were not set in POWERPC_MASKS.  It is
-possible in future CPUs we might want to enable these options
-automatically.  This code moves these options to POWERPC_MASKS.
