+The LD/ST-Immediate-Post-Increment instructions are all Primary
+Opcode: there are 13 of these.  LD/ST-Indexed-Post-Increment
+are all effectively 9-bit XO and consequently may easily
+fit into one single Primary Opcode.  EXT2xx is recommended.
+
+One alternative idea is that bit 31 could be allocated (retrospectively)
+to Post-Increment.  Although it may be too late for Scalar Power ISA
+it **may** be possible to consider for SVP64Single and/or SVP64-Vector
