* VBLOCK sub-execution context (PCVBLK increments whilst PC is paused).
* VL element loops (STATE srcoffs and destoffs increment, PC and PCVBLK pause).
Predication bits may be individually applied per element.
-* SUBVL element loops (STATE svsrcoffs/svdestoffs increment, VL pauses).
+* SUBVL element loops (STATE svdestoffs increments, VL pauses).
Individual predicate bits from VL loops apply to the *group* of SUBVL
elements.
