(VSX Rijndael and SHA primitives; VSX shuffle and bitpermute operations)
* register files above 128 entries
* Vector lengths over 64
-* Unit-strided LD/ST and other comprehensive memory operations
- (struct-based LD/ST from RVV for example)
-* 32-bit instruction lengths. [[svp64]] had to be added as 64 bit.
+* 32-bit instruction lengths. [[sv/svp64]] had to be added as 64 bit.
These limitations, which stem inherently from the adaptation process of
starting from a Scalar ISA, are not insurmountable. Over time, they may
