* LD/ST Immediate has no individual control over src/dest zeroing,
whereas LD/ST Indexed does.
* Post-Increment is not possible with Saturation or Data-Dependent Fail-First
-
-These are not insurmountable problems: there do exist workarounds.
-For example it is possible to set up Matrix REMAP to perform the same
-job as Pack/Unpack, at which point the LD/ST "Saturation" mode may
-be used, saving on costly intermediary registers *at double the LD
-width* if a Saturated MV had to be involved. Store on the other hand
-it is extremely likely that an arithmetic operation already computed
-a Saturated Vector of results, so is less of a problem than Load.
+* Element-Strided LD/ST Indexed is not possible with Data-Dependent Fail-First.
Also, the LD/ST Indexed Mode can be element-strided (RB as
a Scalar, times
