 * identify the scalar primitive
 * assume that longer runs of scalars will have Simple-V vectorisatin applied
-* assume that "swizzle" may be applied at the (vec2 - SUBVL=2) Vector level
+* assume that "swizzle" may be applied at the (vec2 - SUBVL=2) Vector level,

 Thus for example, where OpenPOWER VSX has vpkswss, this would be achieved in SV with simply:
