instruction unless this bit is set, in which case REMAP "persists".
Reset (cleared) on use of the `setvl` instruction if used to
alter VL or MVL.
-* Pack - if set then srcstep/substep VL/SUBVL loop-ordering is inverted.
-* UnPack - if set then dststep/substep VL/SUBVL loop-ordering is inverted.
+* Pack - if set then srcstep/ssubstep VL/SUBVL loop-ordering is inverted.
+* UnPack - if set then dststep/dsubstep VL/SUBVL loop-ordering is inverted.
* hphint - Horizontal Parallelism Hint. Indicates that
no Hazards exist between groups of elements in sequential multiples of this number
(before REMAP). By definition: elements for which `FLOOR(srcstep/hphint)` is
