There are unfortunately some inviolate requirements that directly place
pressure on the EXT000-EXT063 (32-bit) opcode space to such a degree that
it risks jeapordising the Power ISA. These requirements are:
it is a pure **Scalar-only** word-length PO Group. It may remain `RESERVED`.
* **`RESERVED1`:{EXT200-263}** is also a new set of 64 word-length Major
Opcodes.
- These opcodes do not *need* to be Simple-V-Augmented
- *but the option to do so exists* should an Implementor choose to do so.
- This is unlike `EXT300-363` which may **never** be Simple-V-Augmented
+ These opcodes would be Simple-V-Augmentable
+ unlike `EXT300-363` which may **never** be Simple-V-Augmented
under any circumstances.
* **RESERVED3:`SVP64-Single:{EXT200-263}`** - Major opcodes 200-263 with
Single-Augmentation, providing a one-bit predicate mask, element-width
